Hia all..

my cpu has a max vcore voltage of 1.125. the bios is set to 1.125. cpu-z, the bios and sandra all say its 1.144.
A.O.D. tells me its 1.125. which do i believe ? btw everything is running fine and cpu temp is usually under 40c.

Thanks !

That is VDroop it is normal google it.

Confirming that SAAIELLO is correct about vDroop.

This is a design principal that allows them to create boards with fewer costly capacitors.

hiya's and thanks for the tip on vdroop. i think what i have is 'vhike' lol. i want to run my vcore(1.125v) and whole system at spec. everything ive read on vdroop says it drops your vcore. mine is up by 0.019v.
maybe its just that its impossible to get every make and model combo to work/read right.
like my lone stick of pc2 6400 ram. cpuz show it running at only 371mhz x2, instead of 400, with my old cpu - athlon64x2 5000+ AM2. when i went to the phenom, it fixed the problem. but then i noticed my memory score in passmark dropped by 100+ points with the phenom chip ! so what gives ! 9800 gt should be scoring higher.

peace.

^ vDrop can also increase vCore when not at 100%. Try running Prime95 and see what happens to the vCore.

I'm unaware of any benchmarking software that computes the system memory score with your graphical adapter. That would be a bit silly. =)

Your memory was acting fine, it's the way the memory controller in K8 processors worked, they had some sort of multiplier related divider for ram speed. Ram only ran at full speed with certain cpu clocks, and ran at a divided speed at other clocks. K10 doesn't have that divider, so ram always runs full speed with k10 processors.

cool.. good to know ! thx loneninga !

i was referring to my system ram and those stats show it. windows 7 aero assessment seems most accurate. constant 5.5 and 5.9 memory score when im running vista 64 ultimate.
about the 9800 gt.. what i meant was, i noticed it too was getting low scores 'in general'. it should own a 7900 gtx. i was not comparing it to my memory.

shadow.....i ran it for almost 2 hrs.. 42 tests completed, no errors. i checked cpuz part way and it still read 1.144.
ive notice too that some system devices are using microsoft drivers, smbus ect... any tips there?
