Q6600+MSI P35 Neo2 FR PSU problems

atmadden · 21 Dec 2007 at 12:38

I have the following setup
Q6600 GO
MSI P35 Neo2 FR bios 1.6
2x1GB corsair xms2 cas4 at 800
PSU'S 2x coolermaster M700w and akasa paxpower 460w
MSI 8800GTS 512

I am having major problems with this setup it wont boot with either of the above coolermaster psu's both brand new from different etailers both of the the fans and led's come on for a split second then nothing. The akasa psu will boot the system fine but when it comes to overclocking I can't get it much past stock it will just reboot when stress testing. Temps go to about 65c under load have tried a sycthe ninja and a swiftech watercooling kit. I suspect the akasa psu can't cope hence purchasing the coolermaster. I am a fairly experienced overclocker. Any ideas?

I have a Q6600 SLACR & MSI Neo2 FR and have had no problems at all with it.

Spec below

q6600 @ 3.4
Neo2 FR
8800GTS 640mb
4x1gb Crucial Ballistix PC6400 @ 1100mhz
Noctua NF-U12

X-Fi Fatality
5 USB port PCI card
2 x Pioneer 109 DVD-RW
Akasa Eclipse Case

Have you tried re-seating the CPU?

Running memtest?

What voltage is the CPU & Ram at?

Slacken the ram timings to 5-5-5-15 for booting purposes as well. The corsair is not the greatest ram OC'ing as well.

What thermal paste are you using for the CPU? Also check that the coolermaster PSU are delivering enough juice on the rails for that system (I doubt that though)

Have you tried going back a bios version. I'm on 1.5 and see no reason to change currently.

Let us know bud.

im running the same MB and CPU (with 4 gig ram and 8800gtx).. I have only spent an hour playing with the clocking since I installed it last week, but have had no problems with PSU and am running at 3.3GHz using a rather old 650W Enermax.. I am using 1.2 bios and have no trouble..

I would also recommend running memtest and fiddling with memory settings as I have mixed up PSU and memory problems in the past!

I have tried it at 400x9 and x8 and x7 and x6. It is only stable at x6 setting so it can't be the memory. I am only raising the multiplyer at the moment and the ram is running at spec.
