Hmm.default vcore on Opteron 170 is 1.38v???

[nealh]

I popped in a 0em 170 0546 xpmw and at auto settings my bios reports 1.38v...my opteron 165 was 1.33

this is on DFI SLI DR

what default vcore are you getting..I thought opterons were 1.3-1.35v???

It is probably "physcially" in the 1.3 - 1.35 range but the voltage is being reported inaccurately by whatever software proggy you are using to view it (even the BIOS won't necessarily report it accurately). Only way to be sure is to test with a VMM.

 

[nealh]

no I understand accuracy is off except via VMM

However my Opteron 165 reports 1.33, the 170 1.38....it clearly is defaulting to higher voltage

place chip in socket..set auto...and vcore is higher on the 170 vs 165

put both chips in the same physical motherboard, and then tell us what it says.

i think that's what he did... ?

 

[nealh]

both were put in same mobo...DFI SLI DR..bios 623-2

opteron 165 defaults to 1.33
opteron 170 defaults to 1.38

Might as well OC it until 1.38v isn't enough.

It does not appear to be as good as a chip as my 165..which did 2400 at stock..600mhz

I slapped it in...after 2 hrs crashed dual prime 95 at 1.46vcore @2700..winxp locked up
it had been installed only for about 15min

I was slower and more methodical on my 165 OCing..started at stock prime95 for a few hrs then moved to speed it failed increased vcore and prime 95 for few ..etc

But I wanted to see if I got a good chip..I am going to go back and move more slowly but it appears 2800 will require 1.55v(1.375*113) at least..not(I doubt it) sure if this will run dual prime95

what I found was if I post slowly and load xp slowly..not enough vcore at that speed...if it does a crisp post and load..usually I am close to needed vcore to Prime95
