Ideapad Y510P

is it normal for the ship date to be delayed an extra two months...?

 

Anyone see an issue with using one of those china made HDD caddies that supposedly fit in the ultrabay to fill the empty slot when I remove the extra 750 from the slot? The caddy will be empty and just a placeholder to keep dust out. I wonder if it will cause any errors since it will be plugged in to the slot but with no actual drive in it. I rarely run SLI and my battery life increases dramatically when I remove the second card. Just don't like the hole in the side.

 

Anyone seen this? Buy Lenovo IdeaPad Y510p Touchscreen Laptop - Microsoft Store

Saw this through a post on the Lenovo forums ( IdeaPad Y510p Touchscreen version? - Lenovo Community).

Now I don't know what to do....I just got mine and I like it. I don't really care about the touch screen, but it's better to have it than not. Wonder if I should return mine and wait...(since I'm still within the return period).

 

I doubt the touchscreen is worth 190$, as you can get the same config from newegg for 1060$.

 

@ohfoohy: its about 10-30 frames less..

10 watts is a guess but the entire CPU only uses something like 50 or 60 watts so 10 watts is pretty good. There really isn't a guide but I used Intel XTU utility and just used the core voltage offset and started at -75mV and went from there (stress test, change voltage, repeat). The max people are seeing is about -120mV. You can also do the same to the iGPU and CPU cache.

 

Ok...had to look up differences between watts and voltage but I think I understand. ><
I'm gonna lower the voltage...which is how fast the amps are going through my system, which will lower the overall watts.

So what area am I looking at in CPUID HWMonitor (free version). Does this log it also? I have Voltages for "VID" at 0.677 min and 1.090V max and another area "VIN0" at a steady 0.825V.

I'll go download intel XTU utility and do what you said in the meantime.

What's this about iGPU and CPU cache? What is that and how does it help to lower it?

 

If you don't know what those things are then I suggest to do a bit or reading before trying to undervolt your CPU.

 

Ok. IGPU = integrated graphics card and cpu cache is like a temp file kinda thing that stores things that you access a lot...

So I should undervolt those things too? (undervolt = underclock?)

Btw...I understand lowering by 75mV, seeing how it works, then 80...90...100, but let's say I undervolt by 150mv and it's too much. What happens? Computer won't turn on? If so, how would I undo that...

 

Does anyone here run a triple screen with this laptop, i.e. 2 external monitors + the laptop screen? I plan on buying 2 24" 1920x1200 Dell monitor to hook up to my Y510p but I'm not sure if that's feasible.

Thanks,
Joe

 

Undervolting does not equal underclocking. Undervolting just lowers the voltage a processor runs on (think of it as using a lower octane level of gas then what the car manufacturer recommends). Some CPUs can run on lower voltage and still run at the same speed without problems. This is a side effect of the manufacturing process and it is totally different for each chip (some may undervolt, some won't and some require MORE voltage and those are then underclocked and sold as slower binned chips wtih different names). Underclocking runs a CPU at a slower speed (lower Mhz) and not only will this reduce temperature but it will also allow you to undervolt it more. I would start with just the CPU and then maybe try the iGPU or cache. If you are running SLI then undervolting the iGPU won't help since it isn't used anyways. You can also overvolt a CPU in order to overclock it higher (but some chips will also overclock with no additional voltage needed)

The intel program works on the fly so when you drop the voltage and run the stress test it will either complete the test (and you know it is working then) or it will crash and reboot the laptop (this will cause all your changes to reset back to default). I would recommend running the test for 1 hour when you get close to the limit (I found several voltages that ran fine for 5 minutes but would crash after 45 mins).

You CAN damage your computer if you select a voltage that is too high (or possibly too low) so stay within the boundries of +/- 120 mV.

 

Alright. Was also reading this guide so I think I understand what's going on.

Downloading XTU now.

 

"core voltage" in xtu can't be lowered? It's at "default" but can't go lower. It can go higher though...

There's "dynamic CPU voltage offset". That's what I want to tinker with?

 

Yes, that is a slider and you can just move it to the negative side and then go to the stress test (on the left) and run the stress for core for a while. Once you found one that works for you make sure to save those settings so you can reload them after a crash occurs. Then play around with your iGPU and CPU cache voltage offset but I found at least that those don't help as much as the CPU.

 

Hi,

I'm planning on picking up the SLI verison from Frys and the website says that the y510p comes with an 8GB SSD, not the 24GB listed on Lenovo's website. Can anyone who's purchased this machine at Fry's confirm that it comes with the 24GB SSD? Also I'm assuming (from reading the forum) that it comes with the 4702 not the 4700.

Thanks,

-Ben

 

No idea but if it does come with the 8GB then it isn't the SSD model, it is just the SSHD Seagate drive with the 8 GB SSD cache built into the HDD. It also might not have the M.2. socket on the motherboard which will limit your future upgrade options.

 

Thanks.

That's what I thought, but I wanted to confirm. It's listed as "1TB HDD storage + 8GB SSHD Hybrid" So it looks like the 8GB is the cache.
Guess I need to order from Lenovo to get the 24GB SSD.

Ok, didn't realize it had stress test built in. Was using prime95. So why do we have to play around with it if we all have the same CPU and laptop. Shouldn't we all be able to undervolt to the same amount?

After several tests, I've run into some odd results. At just 5 minutes each, the CPU core temp as reported by XTU is giving the opposite results I would've expected.

Default voltage stress test: ~75 degrees very steady
-82mV (sliding it to the left...) stress test ~ 80 degrees celcius
default voltage stress test: ~75 degrees very steady
-100mV stress test: ~ 82 degrees, but fluctuating quite a bit, with it usually between 80-90 degrees
default voltage stress test: ~75 degrees very steady
Anddd just to check
+80mV stress test: ~75-80 degrees, quite steady


Shouldn't less voltage lower the temperatures?

edit:
stress test -100mV - 28-32 watts under "package" and 3.19ghz processor frequency
stress test +100mV - 35-40 watts, 2.39ghz

Am I doing this backwords???

 

Microcenter advertised my model as having only an 8GB SSD also but it appears I have the 24GB SSD model according to the drives listed. Either that, or they just added a second partition that just happens to be around the 24Gb size. I have not removed the bottom cover as of yet to see if the SSD is there or not.

 

Hi all! I have been doing research for quite a while and have become quite convinced that the y510p is the right laptop for me, but I do have a couple of questions that I was hoping I could have answered before I jump the gun:

1) I noticed that one of the non-SLI versions houses a gtx 755m. Are there plans to release an SLI gtx 755m model in the US? I have seen that some other countries already carry it, so perhaps one is coming to the USA soon?
2) Where on earth can I find ultrabay accessories for the laptop? All I have been able to find is the ultrabay gtx755m. I was really hoping to be able to get a bluray reader and extra battery, but cannot find them anywhere.
3) I noticed that the more expensive models have the 24gb SSD for caching. If I was to buy a bigger M2 SSD, could I use it as a HD seperate from the terabyte and technically have 2 hard drives, or do they have to be used together with caching?
4) I have seen quite a lot of discussion about the processor, the 4700mq, and its turbo mode. Can I enable the turbo (up to 3.4 ghz) in the default bios or do I have to use a custom bios or something?
5) Is the CPU soldered onto the motherboard, or is it removable? I ask because I might eventually want to upgrade it.


Thanks for the help everyone!

 

1. Lenovo rep said this November
2. Look for y500 ones. They are pretty rare.
3. You can boot off an M.2, so you can use it as your OS drive. However 24GB is way too small, you will need a 3rd party one (try: MyDigitalSSD)
4. Turbo is enabled by default. However if you push this system too hard, it might disable turbo (called throttling) to prevent from frying itself. Undervolting is a solution to this.
5. CPU is not soldered, since it is an "M" CPU. However replacing your CPU voids your warranty, unless you buy from XoticPC, they can ship the model with up to 4930MX.

 

That is just another partition on the hard disk. If you have the M.2 SSD cache, it's not viewable in Windows Explorer, only in Disk Management and in DiskPart in Command Prompt.

 

I haven't ordered the laptop yet, but is it not possible to use the M.2 as its own hard drive? Does it have to be cache? I was considering getting a larger capacity M.2 drive and using it as an OS and gaming drive and having the terabyte for other data. Is this not possible?

 

Thanks for the info. I removed the bottom cover and indeed the M.2 slot is not there nor a connector on the MB for one such as was the case with many Newegg models as well. I'm not concerned as I wasn't planning any upgrades anyway.

 

CPUs are all different because of the manufacturing process (picture dropping a scoop of cookie dough onto a cookie sheet and baking the cookies, they will all have a slightly different shape once they are cooked even if they use the same amount of dough). If they ALL could be undervolted then they would sell them at that voltage. From the looks of yours your undervolt is allowing it to turbo higher because of the lower thermal load (which is good) so you are probably doing it right. Your laptop is probably doing a lot of throttling of the CPU at default voltage to control the heat (the same as when you increased your voltage). You can adjust your turbo levels of well (I did) and that will reduce heat and allow it to run in turbo mod for longer.

 

Anyone here is able to help me out? Much appreciated.

 

Sorry no idea but if you look up the specs for the iGPU and the video card then that will tell you if it is theoretically possible (but doesn't mean the laptop itself will support it)

At work I have a thinkpad and we can only use 2 monitors at a time (external plus laptop screen or two external screens) but we are using a dock as well.

 

So guys, currently wich site is the best option to buy?

Lenovo, Amazon, Fry, Newegg, XoticPC? Other?

I want: i7, SLI, 16GB RAM, 24GB SDD, 1080p.

 

Sorry I did that backwords.

stress test -100mV - 28-30 watts under (under "ia cores") and 3.19ghz processor frequency
stress test +100mV - 21-24 watts, 2.39ghz

And I'm assuming ia cores are the cpu

Shouldn't the CPU be using less watts since I've undervolted?

Hmm XTU shows 0% under CPU throttling during stress test at default voltage,, and even +90mV

Is it throttling without showing it there?

"From the looks of yours your undervolt is allowing it to turbo higher because of the lower thermal load (which is good) so you are probably doing it right. Your laptop is probably doing a lot of throttling of the CPU at default voltage to control the heat (the same as when you increased your voltage). You can adjust your turbo levels of well (I did) and that will reduce heat and allow it to run in turbo mod for longer. "

So...paraphrasing what you said: lowering voltage means less thermal load, which means computer thinks hey I can turbo more, which raises temperature -.-

If that's true, how do I adjust turbo levels? Is that the multipliers active core 1 through 4? If so, recommend any levels?

 

Shop around and compare, Lenovo is pretty cheap though since its straight from the manufacturer..

 

Yes, I am using 32x/31x/30x/29x for my turbo ratios. It runs a tad slower but because of the lower heat it runs at these speeds much longer so I am reallying getting better performance out of the processor. I was able to run mine at 100% load for 1 hour at 2.9 ghz after undervolting (stock speed is 2.4 before turbo) compare to before were it would drop down to 2.4 Ghz after 1 min of full CPU load.

I guess you could set them to something like 30x/25x/25x/25x and it would run really cool because it would run at basically 2.5 Ghz all the time and you would produce much lower heat.

But again I will stress that each CPU is different and some with respond better than others to undervolting.

 

Cool, tried it. getting 2.89 GHz but still getting ~80 degrees. What's next to tinker with?
Processor Graphics voltage offset and processor cache voltage offset? If so, any recommendations?

 

Yep, I am getting about 77c after a 1 hour test. I lowered my iGPU and processor cache by -75mV as well. I think I have more room to lower mine but I haven't had the time to play around with those.

 

Oh, are you using the iGPU for your day to day video or are you using the Nvidia GPU? To check right click on your desktop, go to the Nvidia Control panel, then go to 3D settings and make sure that the preferred graphics card is either set to auto or integrated. That will lower you temps a bunch as well. If set to integrated then you have to make sure to switch it before gaming but otherwise it will be plenty powerful for day to day stuff.

 

My Y510P SLI is on its way

If I just wanted to use it for the weekend as a business laptop, e.g. ditched the 2nd graphics card, do Lenovo supply a cover, or are your left with a big hole?
Not that I will be doing that very often, but it would be nice to have the choice.

 

Hello guys. Could you tell please, if I use on my Y510p in a special program only CPU, without GPU, but with 100% load of 4 cores, would it throttle?

 

No cover as far as I know unless you buy a ultrabay accessory to replace it (live the DVD drive or the fan).

 

Amazon.com. They have absolutely fantastic customer support and return policies, and they have pre-assembled units in-stock and ready to ship immediately. If you have Amazon Prime, you can get next-day shipping for $4. You can order the laptop now, and have it in-hand by tomorrow evening.

Big hole.

Official Lenovo parts for that slot are the 2nd GPU, optical drive, drive caddy, or a cooling fan. That "cooling fan" is probably the closest thing Lenovo has to just a plain slot cover.

There are some people that have had success buying standard drive caddies, and putting them in that slot. You could always buy one of those for about $12 and just stick it in that slot (even without a drive in it). It will at least cover that hole, and give that side of your laptop a bit more structural rigidity.

 

Unlikely.

Intel CPUs by themselves don't really generate all that much heat. Especially in a laptop like the Lenovo Y510, where the cooling system is engineered to cool both a CPU and high-powered GPU as well.

Running CPU alone will not cause any thermal problems on this laptop.

 

Okay, cool thanks.

 

I read that Y510p has some turbo boost problems, but in my case I guess it will be okay?

 

It won't "throttle" but it will only run at 2.4 Ghz if you run all cores at 100% unless you are running something for only a few seconds. At stock voltage the CPU can only turbo for maybe less than a minute before it drops back down to 2.4 Ghz. If you do some tweaking with the voltages and turbo ratio you can get it to run at 2.9 Ghz on all 4 cores with 100% CPU load.

 

Basically the heating solution is inadequate and it can only turbo for a few seconds before it overheats and drops back down to 2.4Ghz. I undervolted mine and changed the turbo ratio and I can turbo for 1 hour at 2.9Ghz.

 

What do you think about this advice? Short & useful notice for Y510p owners / wishers about CPU turbo boost throttling and solution

 

Yes that is well known. You can't really look at the I5 results because that is a dual core chip but the I7 certainly will throttle when the Nvidia GPU is loaded. Throttlestop works well but it will also cause A LOT more heat as a result. Others (like me) got for undervolting and adjusting the turbo ratio to get more performance out of their laptops.

There is an entire 100+ thread about throttle stop in these forums you can read if you like as well.

 

Thanks. And one more question about undervolting - is it safe for the laptop, are there some risks? e.g. to burn the cpu putting wrong voltage lol.

 

There is always some risk when you do something like this but if you look back at my previous 10 or so posts in this thread you can see that I walked somebody through the process who had little experience with this sort of thing.

I think it starts on page 217.

 

If you shut off a core on your i7 it will stop throttling

 

Any y510p owners playing BF4?

I wish they would patch the damn game already.

When the game works properly it runs great. Pretty sure everything is on high as default.

 

I am playing it on a y410p with a gt755m OC by 10% and I get great frames @900p 50-55 most of the time.
