Hey all,
I have really enjoyed catching up with this thread! Thanks for sharing...
After all the great tips i got here, it would only be appropriate to share the fruits!
for me, 450x9 is the sweet spot. FAST, but not, imo, too much juice. (orthos/everest/occt stable) Striker/8400 with the following settings:
vcore=1.43750v
nb=1.5v
sb=1.6v
cpuvtt=1.2v
cpupll=1.6v
8GB Mushkin #996599 @ 900 (1:1) 5-5-5-15 2.00v
(it works equally well with 8GB of Hyper-X)
At above 4.05Ghz, core temp's will MAX out around 64-65c under orthos/occt, and this is after a few hours. during Crysis they will not reach 50c...
Regarding the latency issue: Does this only apply to 8GB? I know with 4gb @ 475 I do not experience it. I will double check with 8gb. (most attached pics are with 4GB)
I just got the system stable @ 4275Mhz...
vcore=1.52500v (too much for 24/7)
vram=2.2v
cpugtl=+110
nbgtl=+110
nb=1.52v
sb=1.60v
cpuvtt=1.30v
cpupll=1.60v
it is perfectly stable, however will run too hot under stress (occt=74-75c!). I am Air cooling with a Noctua NHU-12P. Stays under 65c in Crysis.
I have not done any sort of lapping... I am sure that would be a huge heat/power improvement. That project is on the to-do list...
500x9 boots and runs windows fine. it can handle Everest benchmark, but no stress tests. it takes1.6v to do it!
3x 8800GTX's + overclocked cpu/nb/sb (a notoriously HOT nb at that) = serious heat management issues. but it can be done effectively with a little work. I can post a follow-up on this w/pics if anyone is interested.
Thanks to all for the great advice/research!
Sam
