Opteron 170 Overclocking question

[Strife2101]

I got a 5hr 20min dual prime stable running a Opteron 170 (546XPMW)
at 2700mhz = 9 CPU Multi x 300mhz fsb on a DFI LAN Party UT SLI-DR Expert. This is with the RAM out of the equation.

I have the voltage on the Processor at 1.4v x 104.8% = 1.4672V
Temps: 21C idle, 33C load, I would add 10 more degrees to each of these because I here the sensor is inaccurate, I'm using a thermalright SI-120 with panaflo fan.

Now in the Bios its telling me the voltage is running at 1.48V, but when I use smart guardian or Everest in Windows XP its telling me its running at 1.46V, which should I believe?

I dont think I have hit the wall yet that starts increasing temps a large amount because there has only been a slight variation in temps as I have went up in MHZ. I got 2500mhz prime stable using stock voltage. If the reading are correct in windows then I might try to push for 2.8ghz. Do you guys recommend a voltage to stay under, if I am going to use this as a everyday gaming machine?

1.46 volts is safe.

try up to 1.5 to 1.55.

with my old 3700+ SD chip, i ran it daily at 1.65 volts with no problems.

my new 170 i run with 1.5 volts.

Yea but do you know if its running at 1.46 or 1.48 I cant tell which one of the readings is accurate the bios or Safe guardian in windows

 

[Shimmishim]

does .02 volts make that big of a difference? IMHO, not really.

the ONLY way tto verify what it is, is to get a DMM and physically measure it yourself

Okay Ill give it a try when I get home from work

I have asked this at extremesystems..the DFI expert temps readings are borked...you get what set in the bios with respect to vcore at idle...not sure if the Expert overvolts like the DFI Ultra D and SLI DR
