After reading bryanyeo's article, I messed around and got these 3 results (I did a few other FSBs, but let's settle on 3).

The usual speed running at 12:8 ratio -

[attachmentid=395215]

Highest FSB so far (1:1), too bad crashes instantly on Orthos....

[attachmentid=395216]

And the current 1:1 24/7 setup

[attachmentid=395217]

1.344v vcore, DIMMS @ 2.00v, rest on stock.

OMG.. poisoned.. clean it away..

Just a small update, got it running 430x7 @ 1:1 now. RAMs at 4-4-4-12 @ 2.1V. Vcore @ 1.360v. Vtt and vNb at stock.
Crashes at ~ 5mins mark in Orthos blend. But hasn't crashed yet in 3dmark06, World In Conflict, UT3 or Crysis.  smile.gif

take memtest windows and run..256mb would do..lets say 20 mins??

or 512mb for one hour..

willing to bet ure NB is undervolted.
and ure fsb termination voltage is not optimal for that bus.

i don't think your NB is undervolted unless your FSB is 500 and since your on a dfi mobo, it should be alright. but if your system crashes, what you could do at most is just increse the NB to +0.1

comment on NB.. tsk tsk tsk

Hmmm, with 4 sticks, my tRFC is pretty high, and performance level is at 12. I'll get a memset shot in later.

ezinger : My temps are 47-48 idle, and 65-68c load. Using the stock cooler with AS5. I have a fan over the northbridge so it's at 38-41c. SB temps are higher at 51c under load, which is about 3-4c higher than my 8800GTX ambient temp. The GTX sits right above the SB, so can't do much about cooling.

dont worry about SB.. they dont get stressed much.. and temps dont fluctuate

try memtest windows.. and run 256mb .. u will see ure nb temps go up..

and dude 4 sticks u need to keep that tRFC high.. better .. not much performance gain.. my sticks are rated at 23..
ocz fans are petitioning against asus mobo's who keeps tRFC lower than 42. which is causing a lot of problem for 4 sticks. in XS
most NB is advisable to keep it lower than 60C..

oh yeah another secret of the ancients a pretty important one

Alas, 430x7 was shorlived, it BSOD on me while playing WiC last night, funny (or not).  doh.gif

So it's back to 380x8 for now. Screens as attached.

[attachmentid=397662]

And Orthos past the 30min mark

[attachmentid=397663]

Gonna try to hit higher this weekend perhaps.... unsure.gif
