i7 temps, anymore room for improvement or are they ok?

Nocky24 · 30 Jan 2010 at 14:02

Just ran a small fft test for around 12 minutes- only ran it this long as apparently the chip will reach 97% thermal saturation when ran for 7 or 8 minutes. I've ran longer blend tests to ensure stability as well though.

Are those temps ok for these settings:

Ambient Room Temp: 20.6c
Push/Pull scythe 1900rpm fans @ 1650rpm Exhaust (Have found no improvement with intake as i have good airflow so having it this way just saves on the dust intake)
vcore at around 1.29v and qpi/vtt at just over 1.3v
(The full spec is in sig)

Also would altering other voltages such as CPU PLL, etc help with temps? I've just got it set to auto right now so god knows what its overvolting it to for a 4GHz overclock.

Cheers

You probably don' need the vcore so high, I have my 920 running 4GHz at 1.25, probably could go lower but haven't tried. Mine came set at 1.36 and it was doing upto 89 at full load, but having lowered it to 1.25 now doesnt go above 80 with a H50 using stock fan on intake.

I am planning on going push/pull exhaust with a couple of 1900 Scythes like you. I did have two fitted but accidently broke a fin on one, with that setup I was saving about 4-5 degrees off the above temps. Didn't have to run them at full speed around 1500-1600 was sufficient.

Sound like more or less the same setup as me then with same temps. I did try it at 1.248 (in cpuz under load, llc enabled) and it just crashes. I have to keep it above 1.264 in cpuz for under load conditions which amounts to about 1.29ish in the bios.

for the voltage and cooler your using those temps are OK. I would try save those settings as a base line and try and get volts down though as most D0 i've used (not many!) / come across need less for 4ghz. Iirc mines at lower atm running at 4.2 turbo & ht on.

What other voltages did you set though? Is there anything else i can increase to help compensate for a decreaing cpu vcore? As i can't really get it any lower than what its at now :/ unless its the qpi/vtt voltage which is causing the bsods and not the vcore.

Your temps look fine to me, turbo stays enabled up to 80C so anything lower than that is perfectly fine.

As long as it's Linx/Prime95 stable don't worry about the voltage, 1.28v is nothing.

CPU PLL should be left alone (usually 1.8V).

lowering pll below 1.8 can help increase stability iirc. mines at 1.7 i think.

Temps are OK.

my temps are running higher than yours shown is that down to the cooling your using i am using a zalman whats your cooling?

I've noticed that your sig says 2000MHz RAM - What speed are you actually running it at? 1910, 1528, something else?

I may be drunk as I type this but I seem to remember that the faster the speed that the RAM is running at, the harder the IMC (Internal Memory Controller) works and thus generates more heat through constantly beasting the QPI. Try knocking the memory multiplier down by a notch and see if that helps with temps (which seem fine btw). It may a knock degree or 2 off on it's own, it may not - let me know the outcome if you try it. However, what would defo shave some degrees off would be to start your OC from scratch.

Again, drop the mem back - as slow as possible this time - so as to exclude the worry of QPI voltages until later (set to something like 1.20 - 1.25). Then start OC'ing the CPU to find out just how few volts you can get away with for the OC you want/can achieve. Then concentrate on QPI with increases to the mem multi and voltages as necessary. In short, try and find your CPU volts first with your RAM running slowly, then throw QPI volts & faster RAM into the mix..

I have got RAM rated to run at 2000MHz but can not for the life of me get it to run at that speed with any sort of decent OC. I suspect that with water or phase cooling it could be achieved but its not happening for me and my Megahalems as it stands (I have settled for 4.2GHz and 1600MHz).

Sorry if this didn't make much sense. Cider makes my thought process somewhat blurry.

This is a very good suggestion

Using a Corsair H50 with MX3. Which Zalman are you using?

Well my memory is at 1528 i think with x8 multi. Managed to get the vcore down to stock, which shows up as 1.248 under load (with llc enabled). QPI is down to 1.235 and IOH upto 1.14 i think. Max temps with small fft and 23.5c room temp now max out at 76c.

I've tried various different ways though trying to get the vcore down lower by messing with other voltages, but with no real luck. Its weird though because most of the bsods i've had have been 124 errors, which has something to do with the qpi voltage i believe?
