What software do you guys recommend to stress-test the cpu?. I have been using Prime95 for ages now and want to use something else. Maybe something new "on the marked"...I feel that running small fft is just overkill and not beeing nice to me at all
Or is it still Prime95 wich is the main test software?

stick with prime 95 and linx

between both of those you should be good

[gjeewaytee]

Ok, but is small fft the way to go?....I never let it run for more than a an hour or two

[Leeghoofd]

There is no such thing as the ultimate stress test... if there no signs of instability during daily use, eg corrupt extraction of RAR files, errors while copying, abnormal program terminations you are fine....

some prefer LInX ( linpack stress tool ) but for SB you need to install SP1 for Win7 for proper testing. Some prefer Prime95 small and blend, some do hyperpi32 ( all cores selected ) FYI I can pass all of them yet still crash during online gaming lol...

I demand rock solid stability personally. I have been going with:
avx linx 20 pass (use most/all ram); easiest to pass but finds bad oc fastest
then p95 6-8hr small fft; hard to pass
then p95 6-8hr blend; hardest to pass when playing with ram
then 3dmark01 extreme 2ish hr loop; watch your temps on gpu

After I passed all that I haven't had a single oddity or crash excepting one application freeze in SC2 which I attribute to solely SC2 or realtek audio drivers.

Hi

no answer for me ?

Thanks

I have SP1 for W7 installed.
That is my issue aswell. I can get pass different stress testing and som benchmarks like 3DMark series, but when playing BFBC2 its all a gigant crash lol. But i know that BFBC2 is abit unstable itself sometimes

Here is my Linx result, but i have no idea what settings to use and what to look for. No errors is all i can read/understand


EDIT: What settings is common thinking about : Problem size, Memory and run (Times or Minutes?? )

Same here. I pass all the usual testing and bluescreen while rendering in 3ds Max. If 3ds Max shows stable I have found no real program that will crash. So Max has become my stability test on this platform.

Re: stress testing:

I beleive most use Intel Burn Test these days:

http://www.ultimate-filez.com/forum/showthread.php?t=9

You'll need to update it with the latest dll but i cant seem to find those instructions at the moment. Perhaps someone else can assist?

Your gflops are a bit odd for a AVX windows (SP1), make sure you download the latest linpack for absolute stability testing . And yes you should you [all] memory selected.

What do you mean by odd...What should they look like and what can be wrong maybe?
I just downloaded from the link in the first post of this thread, maybe old one then?

You should hit 100+

[gjeewaytee]

Just so i understand it right you/TheHardCase says it should hit 100+ and from what i can see i only got 59 right??

[deachus]

Your gflops are a bit odd for a AVX windows (SP1), make sure you download the latest linpack for absolute stability testing . And yes you should you [all] memory selected.

His GLOPS are low because he is running 8 threads (has hyper threading on). You put more stress on your CPU with LinX and SB and Win7 SP1 if you turn Hyper threading off or in the LinX settings select 4 cores instead of 8. Make sure you watch your temps, they will be hotter than that 8 thread run you just posted and your gflops should be around 100Gflops or higher at that speed. I am getting around 130Gflops at 5Ghz right now and get around 120-125 at 4.8Ghz.

@deachus

Lateste linpack will give you more then 100Gflops while runing 8threads, this is the hardest test you can throw at a SB with HT on

[gjeewaytee]

Ahh....thx for helping out guys
I just did a new run with 4.6Ghz and 8Mb of ram at 2133Mhz to see if that could end up different, but it didnt.
Anyway i will now do a test with 4 cores selected in LinX. Is that going to be the same or end up the same thinking about the results choosing 4 cores in the LinX rather than turning off Hyperthreading in bios?

[st0ned]

If you wanna test for stability with HT, download this linx but watch out the temps. It will be harder to pass then linx at 4threads with HT off. I can run HT off at 5 with as low as 1.376 but with HT on I need around 1.392v to make it passe . It will also give you ~100Gflops or very near that, it changes with Ghz and mem frequency/timmings

[gjeewaytee]

Here is my run with 4.6Ghz and 8Gb mem 2133Mhz:


I now chose 4 cores in LinX. Does the result look like they should with those settings? Cause there is no different in the temps when chosing 8 or 4 cores in LinX. The temps are stable around 59-60 Celcius

[PytonOrm]

what linx for AVX ??? i just get new 2600K again most test it

I haven't tested 4 threads vs 8 threads gflops results since the last week of March 2011 but here are my results 4 thread vs 8 thread LinX max mem at 5GHz. Seems 4.5Ghz Club thread was updated 4/18/11 as follows "(Update: 18 Apr, 2011) Run LinX on all the available threads from now on. This is mandatory. It appears that the new Linpack libraries fix this bug. I will test latest LinX tonight and post new results as well.

5GHz - HT On 8 Threads - Sub 100 GFLOPS



5GHz HT Off 4 Threads - 130+GFLOPS

That still doesn't look right. See my screenshots above. I get 130+ GFLOPS at 5Ghz 4 threads and 118-120 gflops at 4.8Ghz so you should be getting around 100 or more.

[gjeewaytee]

I will now do a run with HT off in bios. Chose 4 threads in Linx and 4.7Ghz... How much does the ram do on the result btw ??...I guess i have some crappy sets of Xms3 2000Mhz with 9-10-9-27 2T default. They now run at 10-11-11-24 2T

[st0ned]

You aren't use AVX, use the linX I linked above...

@Deachus

Ahrm pls pls research 1st... I sad last linX, if you did a bit of research you would have noticed that it brought a new HT implementation that gave a pretty nice boost with the whole 8 threads.

My post in LinX club...

For the 1st time 2600K HT ON running all 8 threads hits 100GFlops and kiss 100C in Win7 SP1.

Indeed true, as I like to test everything by myself I went out for some tests.

Ambient temp were 21ºC. I had the AC on so ambient temp didn't change.

OPT1 = Temp from the last Rad [TPA120.3]
Water temp in the res ( It's after the CPU OUT ) = 23~24ºC

Cooling is made by a costum WC setup:

Feser Xchanger 360
TPA120.3
Swiftech 655

The rads are in a cake, like
[fans push][Xchange][fans2][TPA][fans pull]

push/pull by Enermax Magma(69CFM) , fans2 are the TFC midspeed (1800rpm ~88CFM).

Old Linx (==New Linx ) with no HT runing in 4T, voltage 1.408~1.416v

~141w


New Linx with HT , 8T, voltage 1.424~1.432v

~143w







Desclaimer: I had to bump the volts from 1.420v to 1.44v ( in bios ) in order to run HT on without freezes/BSOD. 1.420v freezed after few seconds, 1.435 BSOD after the 2nd run. Also keep in mind that I'vent yet been working in to optimizations for HT on voltages, so what did was just work the vCore out until I got it stable, more can be done to bring vCore to around 1.435 at least, I'm sure.

[gjeewaytee]

I will do a last run on with the LinX you just linked to with HT on and 8 threads. Why dont the my temps change with or without HT disabled/enabled in bios on 4 thread in Linx( the old one i guess) ?? Its not going over 60 Celsius whatsoever
And again...does the timings and Mhz on ram affect the score/result in Linx?

[gjeewaytee]

This one was quite more heavy, but the result is now what it should look like...I needed 1.4V to get 4.6Ghz running that test
EDIT: Trying for 4.7Ghz and now im doing 1.45v...dont like my chip at all
EDIT: Even at 1.5V 4.7Ghz it will not complete 1 run in the Linx, but it passes Prime95 1st selftest. I dont get any BSOD or freeze while doing Linx, but some error messages and Linx continues running at half speed or tourch cause the temp drops from 75C to 60 after about 1.5 minutes in Linx
I dont know whats wrong...

Hi All,

I'm on my 2nd MIVE B3 and seems to have the same issue as the first . Has anyone installed the latest (or any) RST driver successfully? I've tried the ones on the Asus website, but they don't work (stall on restart). Current bios is 1101, but I'll be trying 1485 tonight .. hopefully that works.
