Hi Everyone,
I recently bought components for a new computer and started to attempt my first overclock. From what I've read, a 4.0 Ghz overclock on an E8600 is almost automatic, with 4.4-4.5 being very achievable with most chips. Well, I can't get mine stable, even at 4.0. I did memtest and ran Prime95 for 20 hours on stock everything, no errors. I have tried two different kinds of RAM, both Mushkin and Patriot Viper PC8500 1066 2x2GB. I have been able to boot with a processor speed of up to 4.65, and able to boot at 4.5 with a VCore as low as 1.32 and as high as 1.36, and @ 4.0 with a VCore much lower. But stability is the issue. I can run Prime95 with small FFT's @ 4.4 Ghz and 1.36 VCore for 10 hours, but Large FFT's is the problem. I can't get it to pass Large FFT's any higher than 4.1 Ghz, and I get blue screens running FSX and just browsing the Web with iTunes @4.0, 1.33 VCore. the issue does not seem to be a FSB issue; I have been able to boot into Windows and function @ a 525 FSB. Most of my overclocking has been attempted with a x9 or x10 multiplier. I have been conscious of DRAM speed, testing it at well below stock speed, mostly between 900 and 1000. I measure CPU temps with Real-Temp, and they have been staying mostly below 60C under load, highest temp ever reached under load being 64, and staying mostly in the 54-58 range. BIOS is the most current one, 2301. Blue screens I get are mostly PAGE_FAULT_IN_NOT_PAGED_AREA and IRQL_NOT_LESS_OR_EQUAL, with a few others mixed in. I have been at this for awhile and have messed with a lot of things, including NB Voltage (trying 1.4 and 1.5), and DRAM voltage (setting to 2.1), and manually setting timings, at least the first part of them. I don't think I should be having this much difficulty, even with this being my first overclocking attempt. I believe all my main drivers are current, although if it was a hardware or driver issue, I would be getting instability even at stock settings, right? I'm hoping there is something I've overlooked, and somebody can point me in the direction. Here are my specs and BIOS settings:
Western Digital 500GB 7200 RPM
Superclocked EVGA GeForce GTX 260 896MB Core 216
COOLER MASTER Silent Pro 700
Patriot Viper PC8500 1066 2x2GB
ASUS P5Q Deluxe LGA 775 Intel P45 Intel Motherboard
Intel Core 2 Duo E8600
Noctua NH-D14
And most recent BIOS settings resulting in BSOD:
AI Tweaker:
Ai overclock Tuner: manual
CPU ratio setting: 9.0
FSB frequency: 444
PCIE freq: 100
FSB strap to NB: Auto
DRAM freq: 889
everything Auto then

Thanks again for the help. At this point I'm very frustrated and I'm hoping someone can guide me in the right direction.
