Your running just a single card or sli/xfire?
Trying to figure out what kinda load your putting on that to need such a hefty supply?
Time to test mine and see if i need something more beefy.
single X1800XT @816/981 with gpu at 1.575v and mem underclocked 1.985v with watercooling which is the only thing in my rig able to push my 1KW psu's 12v rail down from 12.19v to 12.15v while under load! cpu dual core @2.9ghz at 1.6v 12v rail is steady at 12.19v
also have 2x 256MB BFG 7800GTX SLI @558/1386 stock heatsink air
3dmark05 = 12,111 single card

suicide on water :)
What do you mean "or"? You were using both at different times and you still couldn't OC that high? It has been suggested that my modstream 520W is holding back the OC on my 170 0550upmw but i was pretty skeptical of that since I measured the rails etc and it appears to be rock solid. Very nice OC BTW.Quote:

But now with the Zippy 700w....priming @3.30Ghz only result in one core error out but the other core kept going, and can boot straight into windows at 3.40Ghz so yea these Dual opty draw mucho power so a beefier powersupply is pretty much one of the major key for stability at high overclock. Cooling the pwmic area also help with stability big time as mine would get random prime error or game crashes if the pwmic get to around 65'C.
Hmmmm...5 skins for a PSU is a lot:hm:
5 skins?
You can get the 850ssi for $400.00.
I dont completely understand this, if your rails are solid under full load then your not being limited by psu?
If they flucuate its time for a new one?
My little 520 power stream powers everything in my rig, and under dual prime the 12v=12.05, 5v=5.05 and the others are dead on.
According to one of those sketchy psu calculators i need a 600watt psu for my rig. hmm
Finally had a bit time to tweak down the needed VCore for 10x300 on my Opteron 170 0550 VPMW ... 10x300@1,360V@h2o :woot:

Maybe i get a Titan 1500 chiller (to keep the water around 15c or so) and keep cpu temps low and also use the advantage of the lower watertemps for the rest of my setup. Chiller is usable 24/7 and can easy be used to cool down also chipset/gfx etc. :toast: Vapo is basically CPU only :nono: and the Cold-Bug is always around :eek: :eek: :eek: ....
that is magic Pete..........really good results
did you pop the IHS yet :p:
Nopes - IHS still were it was ... right now i prime 10x305@1,392 :woot:Quote:

Just got my new CCB1E 0550 from ebay ($328 shipped!! you guys should have jumped on that!) It's looking much much better than my 0534, which I thought was already great to begin with (2700@1.475).
This one wouldn't do 2700 with 1.35v stock voltage, but it looks like it will do 297/298x9 at stock. I decided to try 2808MHz@1.4v, just failed after 3mins.. going to ~2770 now in clockgen. This one's looking great! all with Big typhoon air BTW
165? or 170
and umpw or vpmw
165 CCB1E 0550 VPMW. It was an OEM chip off ebay
I just rebooted and set 309x9 with 133 divider so it's at 2780MHz 1.40v set in BIOS. :woot: Priming it now!
I'm with you. They are completely stable at load, idle, etc. so I wouldn't expect it to be hurting my OC but Eva2000 sems to have benefited and his were prolly stable too.Quote:

I got my CCB1E 550 VPMW dual prime stable at 10x280 with 1.55v. Dunno if thats good or what. Seems avg to me:confused: .
Hey Pete@X those are fantastic results,
you German guys must be using some high powered pumps or/and are really lucky as you seem to consistantly be getting amazing chips! :slobber:
I have a question as I should be receiving my Opty 170 anytime soon (thanks XS member, u know who you are :)). When you use two prime95 to load the CPU, should they be showing loaded at 100% or 50%, because your screenshot has them loaded at 50%.
