Gigabyte EP45 Extreme + E8400 under my -60ish CO2 Cascade
First of all thank you for Gigabyte Indonesia especially Sir Benny Lodewijk that let me borrow this great mobo
well my main purpose here is to test how high FSB she can achieve. my 2nd purpose is to test my beast E8400 since i dont any board so far that can break 620 fsb and my E8400 dont even sweat because its just need 1.6v to suicide at 9x620 and needs only 1.64v to bench on 9x600
System Details:
Intel C2D E8400 Q810A156
Gigabyte EP45 Extreme (bios F6a)
Team Xtreem PC8500 Black PCB D9GKX
Palit 8600GT DDR3
Silverstone OP 1Kw
CPU Cooled with my CO2 Cascade (temp range between -65c to -70c idle)
Memory was ALL Auto execept main timings
first, i tested this mobo on air cooling on CPU and i hit hard wall on 634fsb, adding more volts wont help. after few hours learning about the bios i decided to put it under my Cascade and here some nice results:
booted easily on 9x600 @ 1.66v, after that i start to climb up the fsb using EasyTune 6... my first stop was 5607mhz. next target was 5.7ghz. well its not really that hard to break it...(5700mhz Validation link)
not satisfy on 5.7ghz i decided to put some more voltages on cpu, vtt and mch... well, fsb 642 and 5778mhz broke easily. temperatures still hanging on -65c then i push more the fsb and hit 5832mhz. im struggling start from here... bump more vtt and vmch and finally i hit hard wall at 5886mhz
well, after few more test looks like its not my CPU limiting here. using lower multi wont help to gain more fsb....... need some pointers here
im curious on the board performance so i test super pi 1m and 32m
first i try to test on what cpu mhz it can do sub 9s
well, i think its not bad, with crappy OS (previous DFI installation), loose timings it still manage to do sub 9s at reasonable speed
next i try max stable superpi 1m i can do with this system.
only 5535mhz, even push the Vcore wont help stabilze for more mhz, but the results look good... superpi 1m performance looks fine so far with this mobo
next i try superpi 32m... i found out 600fsb wont stable even using lower multiplier, needs more pointer here...
hmm... the results isn too good... i tried few times and it still just finished arround there.. it should be arround 9min 0xxx to 9min 1xxx zone... maybe the PL would help. its on auto now. i'll try again later...
thats all for now...
