Ideapad Y510P

@unclewebb

Unfortunately in XTU you cant unlock OC bins.
I'm using unlocked bios, and even when OC is enabled in bios, multis set over default, in XTU it is still showing default values.
Tried different versions, reinstalled many times, no success.
So, the bios is not fully compatible, even unlocked ones, with XTU. You cant set OC bin multis, current limitations, and memory ratios, and timings is missing too.

Not just they not using BD prochot, throttling is based on GPUs temperature.
Because GPU0 has a common heatsink with CPU, eventually it will reach 65C, then EC shuts off turbo.( or setting direct 24 multi)

What happens when forcing turbo multi, TS and EC is trying to override each other?

Edit: Did a quick try, setting FLEX ratio to 22 makes throttling going back to that multi. So it could be, they are forcing FLEX, or turning turbo off.

Thanks in advance!

 

@TheSonu as i see it a lot of people got also lucky with their CPUs..mine is crashing on -100mV with default multipliers even though it can handle the intel stress test as soon as i run guild wars 2 on ultra setings on that voltage it crashes so im running at -80mV with temperatures under 81 degrees C on what i suppose is max load so i suppose it should be ok..but the ultrabay GPU goes up to 95 C so im currently deciding what paste should i put on

 

Pssh,

I called Monday and told them "My Ultrabay video card is bad so I need you to send me a new one". 15 minutes later, I had one on the way. So far, Lenovo's support has been good to me.

 

ghoula - My new Y510P came from Lenovo with bios 3.05 installed. It doesn't have any useful looking options in the bios but the most recent version of XTU works and allows me to access the +2 bins of overclocking on my 4700MQ. Recently I uninstalled XTU and I have been using a separate little overclocking tool that I wrote. If you would like to help me test it, send me a PM and I will send you a link tomorrow so you can download it. This program accesses the CPU directly so bios or XTU support should not be necessary to overclock and under volt.

There is a register in the CPU that can be used to change or limit the maximum multiplier. Lenovo is changing this register to 24 to limit the speed of the CPU during some high load situations. Users have noticed this when both the CPU and GPU are active such as when gaming. I learned tonight that a stressful task like the latest version of Prime95 is enough to quickly force the CPU down to 2400 MHz even when the Nvidia GPU is not being stressed at all.

The GPU is only at 40C while the CPU is being throttled to 2394 MHz.

dtmwerks - Most laptops slow down significantly as soon as you switch to battery power so your laptop is acting normally. The guys in white coats haven't figured out how to power a high performance CPU and GPU at full speed with today's battery technology. The CPU and GPU are usually both speed limited to reduce power consumption when running on battery power.

 

Mine is not matte...why?

Yes, there are no unlock for the new versions, and cannot downgrade bios. It is exactly what I wanted to offer, to assist development, because i can help testing out stuff with unlocked options.

That is weird, because with prime and linpack i could only make it throttle down to 3.0,and probably it is related to current limit @default 85A. Time to do more testing, but only after work.

 

Still no word on GT755M ultrabays I take it ?

 

They still don't have a working 750m ultrabay for the Y510P so I wouldn't think the 755 will be out anytime soon.

 

They are sending me a replacement 755M Ultrabay and it should be here tomorrow. Is that what you are talking about?

 

Hi..some more questions

Question 1: Anyone else undervolt their y510p? Mine is crashing during sc2 after like an hour of play even though temps are around 60-65. And I take breaks between.

Values
Dynamic CPU Voltage Offset: -113mV
Processor Cache Voltage Offset: -80mV
Processor Graphics Voltage Offset: -80mV

I used to run it at -120 mV for the cpu but that crashed too often. Should I keep "raising" that value? Do the other values matter much for gaming?

I also seem to recall being able to run sc2 fine for an hour or so at -118. Why can my CPU not handle this anymore?

Question 2: Do you guys follow the suggested resolution when you game? I heard you should run games at native resolution of the monitor, which in our case, is 1920x1080 correct? Should I run sc2 as that? Because it suggests something MUCH lower: 1280 x 720 ><

I've been playing at 1920x1080 but realize I get some framerate issues during the biggest games/battles and decided to tweek some graphics. Unless anyone else has some suggestions to improve framerate for our laptop..

Question 3: Related to Q2...I assume the biggest factor is my graphics card. Is there a way to make sure it's running at full capacity? I'm worried it might just be using the integrated card and not the 750m. Would my underclocking the CPU be a factor as well? It's at 28x right now as mentioned before, but it seems it the game only uses 1-2 cores (i think just one actually). I just did a graphics stress test in XTU and graphics frequency maxes out at 1148MHz. Is this normal?

Question 4: Should I be tinkering with any other settings in XTU? Everything I've been told to change is an "offset". But things like core voltage, processor cache voltage, and processor graphics voltage, are at default. What do those do vs the "offset" option?

Hello I am new here and i Just bought my lenovo y510p from Bangladesh.
I am having some problems when updating my nvidia drivers also i have the GT-755m GPU.
When i try to update it to the latest 332.21 driver while installation at the end the laptop restarts and it no longer turns on only a black screen flickers on and off,what should i do?
But if i use the update from lenovos site no problem occurs.

 

there is no point in keeping your temps so low if your system is crashing...you can up the voltage for more stability if you care more for performance then battery life..temps arount 70-75 are still acceptable..I'm running on 76-81 with -80mV on the CPU without underclocking..also as was mentioned earlier underclocking CPU is higly ineffective if your goal is not to save as much energy as possible

to your second question..gaming on native resolution is best for the quality..but is useless if you cant enjoy the game because of the lag..try to tinker with visual effects and if it wont help then lower the resolution...nvidia experience tuning might do that automatically for you..but generally if you play single player games like RPGs lower FPS wont hurt you so much and better visuals up the enjoyment from the game a lot..in multiplayer RTS or MOBA on the other hand you should focus on maxing FPS and response times which means lower the visual quality

Q3..in nvidia settings there is an option to configure graphic cards and settings for individual programs so if you are not sure which one is turned automatically in SC2 then do it manually

cant help with Q4..I only played with CPU voltage offset..nothing else was reducing temperatures significantly

 

How long did it take them to give you your refund? They received my return on Dec. 20th. its now jan 17th and still no refund posted to my CC. I called them 3 days ago. Going to have to call them again. :S

Edit: Just called them again. They have some other companies phone number on their website, how nice. Anyways, finally closed today but still have to wait up to another 7 business days for it to post to my CC. Ridiculous. I think they forget about it since it wen back during the holidays. That's what it seems like. Silliness!

 

Sorry!
Found the solution.
SLI was disabled in nvidia settings, no idea how!

 

Could you expand on this? Underclocking CPU won't help temps?

Also, I read about defragging for windows 8.1 will help performance, but apparently it does it automatically. Sure enough, everything is "ok" status in defrag settings, but there is a drive called //?/Volume{5b9ea64e-7526-4add-bf7b-c0f9efdd0d69}/ that "needs optimization (36% fragmented). I click "optimize" but it doesn't do anything. What is this drive and how do I defrag it?

 

It will, but you can only undervolt so far until system stability takes a toll.

 

I've noticed a few things, but correct me if I'm wrong. I run HWmonitor since realtemp doesn't show GPU temps.

GPU stress test doesn't raise temps of my GPU much or at all...is it just reading it wrong? In fact, GPU stress test raises CPU temps. If I'm having FPS issues and performance issues with some games, it's pretty safe to assume it's my GPU doing the bottlenecking as you call it, since my CPU never runs even close to max when gaming. Would it be a good idea to overclock the GPU a bit? Especially since the temps on the GPU seem to be fine? Or should I use another program to monitor GPU.

Or do I need to gather more information. Maybe my GPU isn't working to it's full potential during gaming? I haven't touched much of those settings except "processor graphics voltage offset -77mV

Laptop still occasionally doing that thing where it maxes processor frequency for no reason. 1 active core. It's showing this on both XTU and realtmp 3.7.

Last 5 minutes nothing on except firefox with couple tabs, all text based. 2.79 GHz and temps 10 degrees above idle at 50. Maybe a backgroudn task is going on? But max frequency really?

 

dtmwerks it was already answered to you by unclewebs
"dtmwerks - Lowering your multipliers is underclocking your CPU. What most people don't realize is that a slow CPU is an inefficient CPU. The ideal CPU runs fast when it has a task to complete, gets its work done as fast as possible and then immediately goes back into one of the low power C States, preferably C6 or C7 where voltage and power consumption approach zero. As soon as the CPU has more work to do, it should instantly get back up to full speed. This is exactly how Intel has designed their CPUs to operate. With each generation, the amount of time to go from idle back to full speed has been reduced. Running a low multiplier when lightly loaded is the last thing you want to do. It doesn't save power because you are forcing the CPU to spend more time in the C0 state as it slowly works to complete a task. More time in C0 means less time in C6/C7 where the CPU saves power.

Here's a good paper from some smart guys at Berkeley that explains this further.

Power Optimization – a Reality Check
http://www.cs.berkeley.edu/~krioukov/realityCheck.pdf"

so in short:
undervolting = lowering your CPU voltage - affects temps, affects stability, no effect on performance
underclocking = lowering max multiplier for different core load scenarios - lower performance, no stability issues, BUT becuase power draw = temperatures and as unclewebb states - with lower clocks finishing the task takes longer compared to default settings - power saved by lower clocks is lower than power consumed by longer C0 state (max perf state) and more power draw = more generated heat
undervolting + underclocking - lowering multipliers allows you to undervolt further and keep it stable..but why would you do that to this beast?
surprisingly cooling system of this notebook is quite capable or at least i think (someone let mi know if 81C is too much ) so simple undervolting should be enough if you don't expect mirracles from it..compare your systems performance with notebookcheck database if you have a feeling that your system is undeperforming

and to the last one
"Last 5 minutes nothing on except firefox with couple tabs, all text based. 2.79 GHz and temps 10 degrees above idle at 50. Maybe a backgroudn task is going on? But max frequency really?" again if something demands it you can see short max fequency spikes that are better than continuous mid range clocks

 

Hmm I think I sort of know the answer to my question, which is throttlestop...but, I think this was sort of addressed as well...

I put everything back to default in XTU, run a stress test, and yeah my CPU is running at 3.2GHz, but it quickly gets too hot and goes down to 2.4, even lower than my consistent 2.8 when I underclocked..

So what are my options to get temps under control, yet have the most performance when gaming. Undervolt CPU, overclock GPU?

And just did a bit of a read on notebookcheck and they are mostly talking about the SLI. What should of numbers should I be expecting with just one 750m? 1148 MHz for graphics frequency sound about right during a GPU stress test?

edit: Just did another mini test. Was playing sc2 4v4 and my fps drops from 60 to 20 ish during the later stages with the big battles. Curious, I check XTU and change my multiplier from 28x to 32x as you guys suggested. Still didn't help FPS. I undervolted less, still didn't help. I notice my GPU frequency is only at 600mhz during all this and CPU utilization never goes above 25% (not the hardest game to run) So...if my GPU and CPU aren't working as hard as they can and it clearly isn't an issue with my ram, why am I still getting such low FPS?

Also...there is a drive called //?/Volume{5b9ea64e-7526-4add-bf7b-c0f9efdd0d69}/ that needs optimization (36% fragmented). I click "optimize" but it doesn't do anything. What is this drive and how do I defrag it?

Sorry for all the questions...I'm not really sure where else to ask

 

I've been reading around for a bit about the Y510P and finally decided to go with this model: Lenovo IdeaPad Y510p (59375345-16) - ComputerPirates.com (the specs are at the bottom of the page, it uses double GT755M). I've read about some issues with the SLI card though, so now i'm starting to doubt wether i should buy it. Any recent info on this? Did these issues get resolved yet?

 

My 2 cents: SLI models are hit/miss. Going Non-SLI is the safer option, you lose extra GPU power and stuff like Shadowplay, but you can battery life, better thermals, no micro-stuttering and lose half a pound of weight.

Feel free to disagree.

 

I agree Jobine, but I thought the whole idea of the Y510p is the SLI. If you don't get SLI, then there are probably other options out there to save weight, battery, etc over a single GPU y510p, and same or lower cost. Besides the SLI, why would people buy a Y510P over other models? The screen? The speakers? I know that I was looking at the Acer V7-482PG before (when I was thinking of just single GPU).

 

Well, the Acer has only dual-core ULV CPU and DDR3 750M, not to mention the fact that it runs just as hot as the SLI Y510p due to it's thinness.

I bought mine before the Acer came out, it was basically this or the Dell 14z.

 

It's mainly the price vs quality that makes the y510p with SLI attractive to me. As you said, without it, there's better options around. But i haven't found any great alternatives for the same price. If you have any suggestions, they're always welcome!

 

If you're not going SLI, the N550JV is the way to go. Incredible IPS display and great sound, on top of the 4700MQ and 750M.

N56JR has a better GPU if you don't mind a TN panel. Also the N550JV throttles even worse than the Y510p.

/thread derailed

 

I would go with the N56JR like Jobine said. The Y510P blows the 55 out of the water on the benchmark tests.

However, I have the 755m SLI and it doesn't work that great at all. One 755 is great and will run anything you can throw at it. SLI on the other hand, that is a mixed bag.

 

Hey guys. Looking to purchase the y510p to replace my aging asus n61jq. Going to get the sli configuration as it's a great deal with some extra specs put in (16 gigs and higher end wireless card). I'm going to be using this laptop for some video editing and heavy gaming.

I'd like to find out how long the battery this last if I'm doing idle stuff like typing documents in word, playing a 5 minute video clip or browsing the Web.

Also, I'm looking to getting an ultra Bay accessory which is the ultrabay dvd drive for when I'm going out on the road and don't need the sli setup. I see lenovo selling a ultrabay drive for the y500 laptop. Would this work with the y510?

Any answers or suggestions would be appreciated. The deal on the lenovo ends Wednesday so I hope I can decided by then on this laptop based on your responses.

 

5-6 hours is the battery runtime w/o SLI doing light tasks.

 

Im using the y510p whit premiere pro and davinci resolve and works very good. But gets easy hot and the fans are loud.

Thanks for the responses Guys. I'm guesing with the SLI I should be looking at 3 hours max for battery life and the laptop is more than capable handling video editing etc.

What about the y500 dvd drive that lenovo is selling.

Y500 Removable DVD Burner DB36 | Lenovo | (US)

Should this work with the y510p?

 

Yes. It will even allow you to use Optimus when the 2nd GPU is out.

 

Excellent to know.

I have one more question. I see that it comes with a 24GB Msata SSD. Is it possible to upgrade this to a 120GB Msata SSD


such as this one: Amazon.com: MyDigitalSSD 128GB (120GB) 50mm Bullet Proof 4 BP4 50mm mSATA Solid State Drive SSD SATA III 6G (120GB)(128GB): Electronics

and then place my Operating system and frequently run programs on it whilst leaving the primary disk (1 TB 5400 RPM) for data?

If this is the case, and the MSata has at least Sata 2 speeds. Then I will definitely be very happy.

 

First of all, it's not an Msata drive. It's an M.2 drive, which is based of PCIe x1 instead of Sata 3 (however it uses a Sata Disk Controller, giving it Sata 3 speeds). The drive you would want to buy is this one:

Amazon.com: MyDigitalSSD SC2 Super Cache 2 42mm SATA III 6G M.2 NGFF M2 SSD Solid State Drive (128GB): Computers & Accessories

With this said, when looking at SSD speeds, the speed of the actual NAND itself is generally more important that the speed of it's bus.

Also be warned that if you buy the Y510p from a source other than Lenovo.com, it will not come with the m2 connector period. So buy the 1199$ fully featured SLI 755/7260/16GB model from Lenovo, maybe throw in 3 year accidental damage if that suits your fancy.

 

You can buy from any sources. As long as the Y510P model has 24GB SSHD, it will have M.2 connector installed. Having said that I did buy Y510P with exactly the same configuration (16GB/ SLI 755/ 7260)from Lenovo. I plan to use the 24GB SSHD as cache drive and may eventually upgrade it once 250GB or bigger M.2 drive is available. 128GB is a little too small for me.

 

I bought the single GPU y510p. I looked at other options and in terms of price/value, the y510p still came out on top. The 2 ASUS machines listed above are really good machines, but the y510p i bought from Lenovo is comparable in every way and cost me about $170 less (including taxes) and came with a 30day no hassle return policy. So is the single GPU model worth it, absolutely!

 

Anyone know the cheapest place to pick up the y510p with an i7 and SLI 750m's?
Cheapest I've seen is $999 at Newegg.

 

After lurking this forum for weeks I finally pulled the trigger and bought the Y510P about two weeks back and I absolutely love this thing. Got the Dual GT750M SLI with the 16gb of RAM and 1tb hd plus 8gb SSHD for $1050 from tigerdirect.ca (was on boxing week sale). Would've really preferred the 24gb ssd, but at the time could not for the life of me find it anywhere and didn't want to pass up this deal. Start up for me is still relatively quick at 30 seconds.

I'm coming from an almost six year old macbook (blackbook) so you can imagine what the performance upgrade is like for me hahaha, although I can't stand Windows 8. Haven't tried any crazy games, but I can play Assassins Creed and Batman: Arkham Asylum on max settings and get awesome fps readings even with SLI turned off. I had the common issue of the ultrabay card burning my hand, but its gotten better over time (maybe my hand is losing feeling? lol), besides, I've added a cooling pad which really helps.

 

Whichever model you buy, make sure that you get Intel 7260 WIFI instead of Centrino.

 

hello everybody,

Does anyone know where i can find the Azerty y510p or y510 keyboard ( i have the qwertz one ),
i tried to call lenovo but they don't sell the part alone .

thanks

 

Actually, it doesn't make much of a difference, both the 7260 and 2230 operate in single-band N mode.

 

Yep and I haven't had any wifi issues what so ever with my 2230.

 

And just for comparison sake, I haven't had any issues whatsoever with my 7260.

FYI. There is a 7260AC model available, but Lenovo hasn't been using that one.

 

Apparently under linux the 7260AN can use the AC channel.

PS if you guys need help running your Y510p under linux, i'll do my best to help.

 

I'm thinking about installing linux, but from what I've read, it's difficult to get it to even boot properly and not all the drivers work.

 

Dual booting it with windows 8 is a pain in the @$$ but i recommend using your 24GB M.2 SSD as your Linux drive then you won't have any issues multibooting.

For drivers, i know how to get most hardware to work. Tell me which piece of hardware you have issues with and i can help you. I have gotten Debian to work on my Y410p will almost no issues.

 

My suggestion was not about N band. There have been complaints all over this and the Lenovo forum about poor performance of the Centrino 2230 card. People were begging for solutions to fix or to replace the card, which is not possible without hacking BIOS. Lenovo did not offer workable solution but instead replaced the 2230 with 7260 in newer models. So, what does that tell you?

Granted that there are lucky users who have not had problem with the Centrino card. But why risk it? I would avoid the 2230 like a plague.

7260 card has been out for a little while now. I have not seen complaint anywhere. I specifically ordered a model with 7260 card.

 

I need to dual boot because of games . I'm currently running linux in a vm which isn't that bad.

 

Yeah, exactly. Games and productivity software are the reason i'm sticking with Windows for the time being.
