I cant seem to get my E6300 fully stable at 3.013Ghz (430x7).
I have had it up to 3.2Ghz before - POSTING and would boot windows (just) at 3.15Ghz.
I know its not my ram giving out, because its Crucial Ballistix Micron D9 DDR800 stuff....and I've had it boot to windows at 4-4-4-12 @ 1080mhz 2.3v...
Current settings are as follows:
Intel Core 2 Duo E6300 @ 430 FSB (3.013Mhz)
2x1024Mb Crucial Ballistix PC2-6400 CL4 Micron D9 (1:1 @ 430Mhz)
Intel BadAxe2 D975XBX2 Rev 503 2507 BIOS
V-MCH @ 1.7v (max allowable on unmodded board in BIOS)
VCore @ 1.425v (bios)
VFSB @ 1.375v (bios)
RAM @ 2.4v (bios)
Currently running 1066 Strap - "266mhz reference" in BIOS - 1333 strap is unstable as hell, and slooooowww with around 7.7gb/s throughput vs 9.8gb/s on RAM - latency is also 65.7 vs 49.x.
Have read all the info I can possibly read on this board, both here in these forums, and elsewhere.
I have managed to do 28hrs straight Dual-Prime with no errors (stopped after that) using only small FFTs.
Windows Memtest however picked up errors at 775% coverage on first 850mb and 163% coverage on remaining 850mb of RAM.
Also Prime95 ran into rounding errors after 14hrs Dual-Prime under equivalent of Blend test (manual RAM settings to 900/900mb).
Also have seen the odd bluescreen (like...2) and had a couple of games just crash to desktop for no reason (F.E.A.R a couple of times).
System can complete 3dMark no problem, and SuperPI not a worry. I just really want the system 100% stable.
Have tried lower voltages and looser RAM timings, no avail. Not keen on running 2.5v into the sticks, and that sure shouldnt be needed for such a marginal (30mhz) OC on them. With the VMCH at any lower than 1.7v, Prime etc error faster. Not sure on the vFSB and CPU can probably run a little lower voltage.
Using Zalman CNPS-9700NT on CPU - and max temps hit 56*C under full load on both CPUs, fan @ 1800RPM (can spin up to around 2200+).
Any suggestions from the guru's here would be awesome :).
I'm not new to overclocking, but Intel and Core2 are new to me.
Thanks in advance guys :)
