Intel Core 2 Quad Q9300 @ 2.5 ghz
Corsair TWIN2X4096-8500C5DF memory
BFG GeForce 8800GTS (BFG88512GTSE)
A pair of Seagate 640 GB (ST640323AS)
Corsair TX750W power supply
Lite-On 52X ATAPI/E-IDE DH53R2P-08
Samsung 22X DVD +/- R SATA SH-S223!
Also a RAID 10 array of 4 360 gbyte Hitachi's (not my boot partition)
I built this system last November (2008). Its been rock solid running XP-Pro 32 bit, Win7 RC1 32bit and Win7 RC1 64 - its a tri-boot system.
A few weeks ago I started to get BSOD's across all three OS's. Chased windows issues around for a while but finally booted memtest v4 and it showed the memory failed in certain locations.
The memory was 4 gbyte of TWIN2X4096-8500C5D F.
Returned the RAM under RMA and received a new set.
Not sure but I think the revison was higher than what I RMA'd, its now 1.2.
Installed the memory taking all due static precautions and then nothing worked. Zero, zip, nada. No post, nothing on the screen, absolutely nothing.
I tried one stick at a time, no change. I removed all the memory and got a 10 beep post with the unit shutting down after that.
I've removed all connections from the power supply except the MB and GPU.
Still nothing.
I reset the MB's CMOS both by jumper and by removing and reinstalling the CMOS battery. I reseated the GPU card. I tried another monitor.
I then gave up, and went to Corsair for another RMA.
In the meantime I put a single stick of Kingston 800Mhz RAM in there and can't kill it. Memtest runs forever, and prime95 ran until I stopped it after about 8 hours.
I've now received and installed the second set of RMA'd Corsair memory and got exactly the same results - no video, no POST, no BIOS screen, nada.
The system was never overclocked, everything left in auto, and the BIOS screen reported everything correctly from the SPD data - the timing was 5-5-5-15 and the voltage was 2.1v. That's from the original set I had there. Since I can't ever get a display with the new sets I can only guess its working. It does report the correct numbers for the 800mhz stick.
Before I RMA the motherboard, anyone got any ideas? Or does it really sound like the mobo just doesn't like the Corsair anymore? I wish the Corsair versions hadn't changed, one more variable to the pot.
Bios is still at F4.
All help welcome. Thanks.
TIA
