new results.
Again, my Opteron 175 CCBWE 0534SPMW, now at higher volts.
I have it at 1.6V, Big Typhoon.
It has been dual-priming all night.
I have been initially disappointed, it doesn't clock well at lower volts. But it seems that this one really likes mid-high volts. Power consumption and heat indicate that the load is not insane, so I might very well settle for this 24/7 and see what happens long-term.

Going to try your suggestion, kinda risky since I do not have an accurate tempature monitor. (SLI-DR Expert is way off on Opterons) I believe its reading around 20c low. Assuming this is true Dual Priming at 1.568 is still keeping me at ~55c. PWMIC is 41c and Chipset is 43c.
I have everything running smooth at 2.6ghz with stock voltage on my opteron 170. Much more than that and it will become unstable but does not scale at all with voltage. It seems like I just can't get it to play nice with my memory even though all of the timings are really lose. Once I figure it out Ill post some results.
Nobody can tell you how much volts is safe.Quote:

As for temperatures, get a fan controller with thermal probes. If you insert the probe under the heatsink's base plate right next to the IHS on the chip, with contact to the IHS, you come very close to accurate readings. Just mentally add 5 degrees, or "calibrate" by using it on a board with working monitoring first.
Another thing to do is get a power meter and observe how much it is drawing. To produce excessive amounts of heat it would also have to draw a lot of power. This is the main reason why I trust my overclock above, the 1.6 volts dual-core with dual prime does not draw more than my 1.6 volts single-core CABYE.
(disclaimer: yes I know volts kill independently of heat, this is why I say I take my chances)
Well so far,
Raised the Vcore to 1.568
Just passed 2 hours Dual Prime at 10x250 1:1 4x HT
Moving up to 10x255 and trying that.. So Far So Good.
Seems you were correct that this stepping like some voltage.
Judging from my experiance on how warm my HSF gets at a specific temp Im estimating around low to mid 50s for temps..

well got the cpu stable 23hrs+ primex2 small ftts @2650Mhz 1.48V CPUx10 HTx3 (600 in Bios) HTT650 but due to mobo not liking TCCD mem its only at 176.7MHz 1T 2 2 2 5 relaxing the mem timings doesnt help to get the mem above 200MHz stable (unless u count 2200MHz htt220 1:1) Hoping for a bios update to improve compatability with TCCD mem - untill then I am stuck out off syn with poorish bandwidth :slapass:
Edit typo error
Do you have your other memory timings set to Auto, and just have the divider and 2225 set? Or do you have other manual settings as well?Quote:

This is the first positive sign I have had out of this processor, maybe this stepping just requires some burn-in to work well. I'm just hoping for 2.6 (Don't think its worth the effort to go any higher with this proc)

Back to the drawing board I guess...

:p:
after 20 hours? Dude, i think its plenty stable for daily use if it goes that long.
I was messing with the new ASUS A8N32 SLI board..

I thought my DFI board PWMIC temps were holding me back but i basically capped out at the same speeds with the ASUS board.
I just can't get 2.9 GHz primestable. (dual SuperPi 32mb is fine)
2.8 GHz @ 1.4V seems to be the sweet spot..
You think my 12V rail going down to 11.72 could be effecting my overclock?
Anyway, going to be keeping the DFI board.. the Asus board does have some nice features but it was way too expensive ($270). I prefer the DFI bios and I won't be using SLI so it is kind of a waste.
12V goes to 11.72... what did it start at? 12? 11.9? etc.

I've seen it drop to 11.72 underload.
It's a Fortron AX450
I have a 7800GT, 2xSATA HDs, DVDRW, and four 120mm case fans.

You are pushing it for a 450w imo. But hell Im pushing my PCP&C 510 ATX-SLI :P
2x7800GT
2xWD Raptors
2xWD 400GB
2xHitachi 160GB
2x120MM Fans
DVDRW, DVD, CDRW :P
But PCP&C tend to underrate thier Powersupplies. I go from 12.09 Idle to 12.04 load..
I went with the Enermax liberty and that powersupply has really suprised me.
I just got the 500watt version and i was running 7800gtx SLI's, amd opteron 165 w/ 1.55Vcore and some bh memory running at 3.5Vdimm.
My ATX +12V always stays at 12.22, seems like a very strong 12v rail.
ATX +5.0V sits at 4.97-4.99 according to smart gaurdian under CPU load, and 5.02 at idle.
Not for me :(Quote:

So more volts or settle for 2650 MHz?
that's a pretty decent drop IMO.Quote:

The GT's and devices have their own rails, as does the 4Pin CPU connector...

2650 @ 1.4 seems to be great for me, runs nice and cool anyway.
According to this DFI board, it runs at 23C lol while the PWMIC is 36 and chipset is 39.
DFI REALLY needs to fix that.
Glad to see someone else with some GEIL. My memory wont do past 255 ARGE! and it wont even take more than 3.52Vdimm! ARRRGE!
