crapcrasher you haven't put up any updates in almost 2 weeks, not had any further luck?
I've put those settings into mine to see if I have any luck. just started prime95, hope it runs fine without any problems.

Yeah I had to stop, after last post I was close to have stable setting for 8x440 (3520mhz) but the day after where I was close at it, the summer literally exploded here, we passed from 27-28 degree to 34-36 degree now and since I am on air I was unable to push it any further, I even had to go back to a stable 3400mhz, its simple too hot atm to try more experiments on it, so well lets wait when temperatures will go down again a bit.

prime95 has been running for ~4 1/2hrs without any problems so far, temps are into the low 60oCs tho(this is watercooled(not ThermoChill PA120.3 radiator tho, prob be lower temps if it was), hate to see it on air ).

crapcrasher might be time you invested in watercooling ).

for everyday use I'll prob stick it down to 3.2/3.4Ghz, just trying to see if I can get it to 3.6Ghz+ or not(so far the answer has been not).

[fowler003]

~6 1/2 hrs and so far so good, if prime95 can go for anothr 30mins at least(I've found that if t runs for at least 7hrs then its usually good to run 12hrs+) then I can start thinking about trying 3.504Ghz(438Mhz x 8 ) again(didn't have luck before).

[fowler003]

well it went on for 23hrs before I turned it off, going to try upping the cpu clock to 438mhz(3.504Ghz) to see if it works(hope it does as its only a 3mhz, ~20mhz increase).

[fowler003]

for 3.504Ghz(438Mhz x 8 ) had prime95 running for 9 1/2hrs before I turned the pc off(couldn't be bothered to leave running overnight), was playing around with 3.6Ghz(450Mhz x 8 ) yesterday but the pc keeps freezing after a few hrs of prime95. currently trying 3.552Ghz(444Mhz x 8, gives ram 1066Mhz on 333/800 strap), only had prime95 running for 15-20mins so far.

edit: pc froze after ~23mins

Hi Fowler, what voltages are you laying down for those temps ??

[fowler003]

for 3.504Ghz I'm using what crapcrasher put up in his last stable setting(so vcore/vid of 1.325v, but the motherboard adds some so its ~1.37v underload after vdroop), just upped the nb voltage to 1.504v rather than the 1.405v that crapcrasher has.

istn the q9450 varinty limited to 1,3V??
