Opteron 170 - burn in weaker cpu0 core ?

[nop]

sorry for my question, but, how do you set CPUBurn to run at both cores? I'm burning my Core 1 now, tried to burn on both cores but my system just freeze. Want to run my165@2880 with 1.57v. from 1.64v. Thanks for any help.

Eva2000, when I say I ran CpuBurn for two nights, I don't mean 48 hours straight. But 2nights each about 7-8 hours while sleeping, shutting system down while I go to work.

Just wanted to clarify...

thanks for the clarification

From a scientific aspect, you are trying to heat cycle the silicon transistors to improve their performance? Do I understand that right?

[eva2000]

well first 13hr dual cpuburn K7 run helped a tad as 2700mhz at 1.504v cpu0 would error smallFFTs in 3min but now run for 42mins



Looks like it will be a long burn in process

This is interesting

[eva2000]

yes interesting thanks Jochenp

From my experience, the only program that will heat a cpu more than CpuBurn is S&M.
But I can't figure out how to get it to run that certain test continually.

[eva2000]

yay much better now

[nop]

Seem like CPU Burn K7 make a trick for me

Used to need 1.64v. in Bios to prime stable, now 1.57V. In my case, core1 is the weak one. Before burn in my core1 failed prime in 16 min. but now....



will continue prime to see how lond it'll go.

Thanks Plywood99 for the programe and Thanks eva for help me through the setting.

I'm glad to see it is working for everyone. I mentioned doing this on another site and they said I was full of Crapolla...

nop congrats... naked core helps for you i guess

yeah i'm noticing slight improvements as well

[nop]

Thanks eva.

For me, IHS off helped me with the temp, reduce. As for the o/c, it helped me to get a bit more Mhz. That's in my case only, other may vary.

Edit, prime passed 2.30 hrs. on both cores, still going

[eva2000]

yes cpuburn K7 has made a difference i've only done one session of cpuburn K7 for 13hrs and this is what i can do now on cpu0

before cpu0 at such clock would fail stressprime instantly and now

[nop]

very nice eva.

My latest development so far.



Considering went from 16 mins of core1 before it failed to this is a huge difference.

[Repoman]

Hmm, so it actually works.. I really didn't expect it to but I'm burning in my 165 anyway

[nop]

well.....it failed after 6.20 hrs.



Time to burn again

[mag|c]

this is quite impressive, perhaps i should try running cpuburnk7 for a night or two, maybe i could lower my vcore a bit after that?

[nop]

well, after the 2nd burn of core1 for 8 hours



finally i got this...



In my case, CPU Burn K7 did help my opty. I can decrease my vcore from 1.64 to 1.57 with the same Mhz. and did pass prime for 9 hours like it did with 1.64 vcore.

[eva2000]

looking good about to run my 2nd cpuburn k7 session now

[dnottis]

Ok, help me understand how this could possibly help?

Is it a permanent solution? will the chip need to burn in at a later time? Would it help an opty 146?

I mean I can see beating the p1ss out of a chip for 8 hours just to push and punish it but I dont see how that would help with prime stability?

[Haltech]

Does anyone have a working link to that CPUburnK7? I cant find a working link anywhere for it. Thanks.

[nop]

Haltech, i downloaded from here. http://pages.sbcglobal.net/redelm/

It is a permanent solution, at least it has been for me. Iv'e used it on three different cpu's, winnie, clawhammer, Venus opty, and have had good results. I have no clue what it does, or how it does it to the chip. But an unstable cpu can be made more stable using this process...

I'll give it a go. 2.95 at less than 1.63v would be great - 3.0 would rock but I just dont see that happening.
