Stock voltages and frequencies?

[AD-15]

I'll see if it calms down over the next few days.

I'm off to see how low I can take down the volts.

[GoNz0]

oh, dont forget to chkdsk the drives when you crash it !

[AD-15]

To speed things up, is there any way I can test only the CPU under linpack (intel burn test)? So far, I've just been using small memory sizes (500 megs) once I know the memory subsystem is stable, to stress only the CPU. Is this the correct thing to do?

[GoNz0]

intel burn test 2.3

run on 16 cores (there is a bug using 8 cores on I7 CPU's stopping it from using 100% CPU across all 8, 16 cores is a work around)

run a small 500mb test to check for initial stability on 5 runs then run another for all availible ram on a 20 pass.

if it pass's 20 using all ram and you are happy set it for 100 and go to bed.

if its still running in the morning your stable.

[AD-15]

Thanks dude.

For all my testing so far, I've been using 32 threads, not 16 (I did notice the 8 threads not using 100%). Is this just as good?

[GoNz0]

yeh same thing, 8 don't work

[AD-15]

Well, it's doing well so far. 1.33V I think. Once I'm done with all the tinkering and am fully stable, I'll post on here with my results.

Thanks again man!

[AD-15]

OK, all done. Took me ages.

End result:

CPU Vcore: 1.35V
CPU PLL: 1.815V
CPU VTT / "QPI/DRAM CORE": 1.25V <----- Was going to go lower, but due to it dropping under load, I feared this would put a difference of more than .5V between it and the DRAM bus voltage

Bclck: 211MHz
Multi: x21

DRAM Speed: 1688MHz, 6-7-6-18 2T (1.64V)

Hyperthreading disabled

70C max temp under a few hours of intel burn test

I am a little disappointed it took so much voltage for 4.43GHz to be achieved without even having HT enabled. I was expecting D0 to perform considerably better.

Anyways, thanks for all your help guys!

Well done. Good temps. What is your cooling solution by the way?

[AD-15]

They're not so good when you consider it's under water cooling.

I have a Laing d5 pump, TFC 360 rad + 6 GELID fans, swiftech apogee CPU and NB blocks.

Do you reckon 1.35V is a little high for 4.4GHz without HT?

Nah. Sounds about right. I needed 1.3V to get 4GHz, and that wasn't even prime stable.

[GoNz0]

nah ur voltage is fine, and considering each chip is its own entity its whatever it runs at !

BTW, I asked Asus about the problem with my keyboard locking up when using the keyboard control for the LCD panel, and this is what I got in response:

It seems to be a problem with the LCD panel keyboard control. I am afraid to say that we do not have such information for it.

[GoNz0]

well my new revision board packed up today, same as last time (same as your last problem)

it didnt wake up from sleep (1st time i used it) so i forced a shutdown by holding the power button and the rest is history.

really pissed off with it now.

[AD-15]

Sorry to hear that dude. How many boards have you experienced this problem with now?

[GoNz0]

this is the 3rd board thats gone tits up, iirc all 3 have done the same.

this has lived for about 100 hours use
