4710HQ Overclocking

Hi All,

So I have been looking into overclocking and I have had some success. Can someone tell me what slider in intel XTU controls the voltage? as I am running out of power before I am running out of Temps

 

Managed to get 767 points in XTU so far

 

Running out of what power?

You should be able to overclock 2 bins higher that stock. Basically if you can boost at stock all 4 cores at 3.3.GHz, then you should be able to boost after using Intel XTU at 3.5GHz all 4 cores.
From what I understand it all useless, as the processor will throttle down at a certain time and temperature limit before you can sustain load on all 4 core for anything worth while. Meaning that you will just end back at stock, or lower if go over the max TDP.
There is something you can do, but there isn't much in it, maybe undervolt half a 0.1 of a volt, something like 0.05v before it becomes unstable, this might be enough to allow an extra 100-200MHz on current throttling point. Use something like trottlestop to monitor the TDP draw level in real time and HWinfo for the clocks.
Sometime I have found it helps to just under volt the CPU without any overclocking, sometime can allow the CPU to run faster before it hits the TDP wall.

 

You should only really hit the TDP under extreme load. Like running prime95. Even using XTU stess test you never get close to 42w out of 47w. Set the Turbo Boost Power Time Window to 1 second. It will help keep the cpu locked at 3.5ghz on all 4 under load. Depending on your luck, you can overclock and undervolt your CPU. I have mine undervolted by 95mv and still overclocked to 3.5 on all four. Rock stable on my rig. Dynamic CPU Voltage offset controls voltage. -50mv on that setting means the CPU will always be 50mv lower than stock.

 

Yes the overclock/undervolt combo is the best for the 47xx series, helps keep the TDP down and speed up

 

well Hello throttle stop. I have managed to sustain some settings. Also please note that if you battery is charge there is not enough power in order for the system to boost. I have tested this on 240w adaptor
I am now running

37/36/35/33. with a -60mv change in dynamic voltage on XTU. I also have throttle stop running. it seems that this holds the system where it should be!

 

You can bypass the 47watt power limit also by increasing the Turbo Boost Power Limit. I have mine set to 70W and never get throttled.

 

Though that non-extreme editions cannot be bypassed for these types of settings?

In anycase if any of this work, then will be some way around the throttling issues. Lets hope this work for 180W PSU, if it does then that thing might cook.

 

You can bypass those settings. Though you need to restart for the setting to take place. It will increase your temps quite a bit though. Prime95 went from pulling 47W max to 68W. Max temps on my rig went from 75-78C to 80-85C.

 

Okay so I tried your settings and I ran a quick XTU benchmark

Throttle stop was not on.
Settings 37/36/35/35
-60mv
70watt Turbo boost power max.

The bench mark showed 0% throttle on power or thermal.
Score 757, Highest temp 84c, highest clock 3.54Ghz
I hit a max of 53w tdp

So I ran the test again with the -60mv removed
I ran into some issue.
Score 753, Max TDP 57w, Highest temp 92c, highest clock 3.54ghz
I did have Current limit throttle hit 3%

Seems you do need a slight voltage adjustment
Okay so with a -60mv I managed 3.5ghz stable with no throttling at all present. Infact on a -30mv it was the same just the temps were higher

 

Hi guys, just seems you guys know what your talking about so i might ask a few questions,

in the bios this model says enable overclocking when connected to graphics amplifier, i assume this is because the videocard turns off and both fans are dedicated to cpu.

if i enable overclock to level 1, it seems the cpu locks itself to 2.5GHz and intel speedstep gets disable (so no turbo) and it actually underperforms than when not on amp (i.e. overlocking disabled)

can someone guide me for the simplest way (preferably from bios) what settings i should use for a 24x7 overclock for gaming.

i was initially thinking of changing baseclock higher than the 100 to compensate for the 1GHz less, but dont want to do it without some guidance.

Thanks

 

ok, after mucking around with the settings i have some more info.
Alienware 17R2
On bios A06
without AMP, XTU bench highest freq 3.22 score 703
with AMP (default settings) highest freq 2.5 score 617

with AMP with overclock enabled
speedstep enabled
non turbo flex disabled (this is important)
OC level 1 (like default settings)
override turbo enabled
graphics turbo enabled
memory override enabled

I get max freq 3.5 score 733

So its alot better than default settings, alittle better than scores without amp, are there any other settings i should change? or leave it as is.

I also noticed in xtu turbo boost short power max changes from 47 to 72W with these settings

 

That 72W is pointless, the CPU will limit itself to 47W under sustained load on matter what you do

 

That's sad, if you know any other changes I should make please let me know

I would have expected to get more from it

 

Nope, never. All H and HQ CPUs to my knowledge have this limitation. I'm trying to find out if Skylake's HQ/HK chips do, but it's hard to find people who have them so soon.

 

I know intels presentation of the 6820 series was on YouTube and it was mainly showing off how good it overclocked with minimal effort

 

Yes, that's a HK chip. I still do not know if it can hold its load under a long time when overclocked. All HQ chips above x7xxHQ can hold an indefinite amount of power... for exactly 2.5 minutes. I've seen 4.1GHz 4980HQs complete benchmarks like 3DMark Firestrike easily, but these benchmarks run under the 2.5 minute time window, so it's easy to "show off" but absolutely garbage for things like rendering, or unlocked-FPS gaming, etc.

 

Yeah, it almost equates to false advertising if it doesn't hold up for at least a few hours

 

A few hours? If I want to run folding@home for 3 days straight at 4.9GHz and I have the power, it's stable and I don't overheat, an overclockable chip HAD BETTER WELL DO IT.

I haven't for a while, but I used to stream for 8-14 hours in a row. My CPU has never dropped its clockspeeds on me and it's always used quite a bit of power. I don't know a single thing about this "for a few hours at least". I know "it better do whatever I ask of it whenever I ask of it as long as I am within deliverable power and thermal constraints".

 

Agreed

 

I have my i7-4710HQ overclocked to x35 x36 x37 with -20mV on the core and -10mV cache offset.
The only other setting I have changed is the Processor Cache Frequency to x37.
It's been rock solid like this for a couple of months now. I went lower on the undervolt but was getting some blue screens on idle, so this is the sweet spot for me. It sticks at 3.5Ghz constantly when gaming.

My best XTU bench score is 759 marks with the current limit increased from 85A to 95A.

I'm not sure if it's OK to leave the current limit at 95A long term so I set it at stock 85A and my XTU bench score is 745 marks.

I can get a better undervolt at stock clocks, but I decided I wanted to run it overclocked and just went about trying to find the best undervolt that I could get while running the highest multipliers.

I started off with just the overclock and no undervolt and ran it like that for a few days. Just doing my normal stuff, gaming, browsing the web, editing some pictures and video's.
Once I felt it was stable I did a -5mV undervolt and left that for a few days doing the same thing, just running my normal stuff. Then I did a further -5mV undervolt and so on....

This takes a bit of time to find the stable combination of overclock and undervolt, but you end up with a stable system for most of the time while you are doing it.

At the start I was going for a bigger undervolt and was getting a lot of random crashes, so taking the longer approach worked better for me.

I hope that helps!

 

Edit....double post.

 

This is the first time im overclocking a laptop cpu, and i dont understand the gains your getting,

Just with OC level 1 in BIOS on my alienware 17 R2 and no other changes i consistently get between 750 and 765 in XTU and i believe the BIOS overclock doesnt do anything.

Im assuming the undervolt is for temps because with or without throttlestop i dont see any issues with it holding 3.5GHz+ for sustained periods of time

I just thought there would be more performance boost or something, even changing the processor cache to x37 like yours seemed to yield no difference, the first few benchmarks seemed to show slightly lower scores, but how can we trust XTU benchmark when it doesn't fully utilize CPU, isnt there a benchmark that maxes out CPU usage in order to take throttling/heat into account when seeing if an overclock is working?

 

cpu cache oc indeed does very little in terms of performance gains

after modding bios i could to unlock 80x multipiler. thanks a lot DUFUS for his help.
here is 42x,42x,42x,42x:

can you please explain me how to do this ? i have an AW 15 R1 and i want to make a 4Ghz overlock on 4 cores... i made a repaste with liquid ultra

 

follow instruction @ http://donovan6000.blogspot.com/2013/06/insyde-bios-modding-cpu-microcodes.html

Use this microcode: https://www.sendspace.com/file/c40ey5

 

do you have any problem ??? overheating ? blue screen ? the process is reversible?

 

you must risk to do.
yes overheating occurred because of bad cooling in y50. bulescreen occurred because of low voltage/current.

 

can you test please if is stable at 4Ghz??

 

last night i played bf4 multi player @ 4.2 Ghz but during gaming i saw some tdp throttling and clock down to 4 GHz and uncore ratio clock down to 2.1 Ghz.

now i am playing bf4 without issue @ 3.8 GHZ
