Erratic boot behavior
I'm having strange behavior at POST after a cold boot since I've upgraded my Q6700 to a Q9550. Occasionally (about 1 in 10 times) the machine will begin to POST, then suddenly turn off and then back on again. Every time this happens the clock in windows is incorrect and I am forced to change it (incorrect in BIOS as well, not a windows bug). Slightly less frequently (maybe 1 in 20) there is no POST at all: the machine just hangs and I get no video output. I also once got a BSOD at the Win7 welcome screen. I cannot reproduce these issues with a reboot, but only with a fresh boot of the machine. The overclock seems stable, I have already let it run 23 hrs 50 mins in prime (got impatient at the end), it passes many passes of intel burn test, and it passes many passes of memtest and linx. There has been no change to my machine save for a new processor and new overclock settings to match. My specs and settings are below:
MSi Neo 3 FR (P45) @400FSB, Q9550 @3400mhz (400x8.5) with 1.1675V, 6GB Corsair XMS2-6400 (2x1GB, 2x2GB) @ 960mhz (1:1.2) 5-5-5-12 with 1.908V, Zotac GTX570 @stock, Intel 330 series 120GB SSD, OCZ ModXstream Pro 600W. I don’t think I need to list my case, optical drives etc… My MCH, VTT, and ICH voltages have always remained at AUTO and my former overclock with my Q6700 was at 320FSB and identical RAM settings (just a higher RAM ratio before) and was previously perfectly stable and predictable.
I have no interest in building a new machine, and any suggestions to that effect will be ignored. This machine is dated, I realize, but I like it and I want to figure this thing out. I have a read-only OS, so I highly doubt something windows related. My temps were monitored during all my initial stress tests and CPU never peaked 61C on the hottest core, and I have checked all connections within the mobo. I’m really hoping one of my AUTO settings just needs adjustment. I look forward to any advice,
