Coolermaster 1000 Case
Antec Real Power 850w PSU
eVGA 680i LT MB but I was able to flash the BIOS to 680i P31
Q6600 G0
Thermalright Ultra Extreme 120 HSF
G.Skill 4GB PC6400 5-5-5-15 RAM
eVGA 8800GT x 2 SLI
WD Raptor 150X
Second, this is what I have my system overclocked and stable at:
3.3Ghz with the following setup:
9 multiplier with a 1480QDR linked and synced with my RAM
Core Voltage = 1.36
FSB Voltage = 1.3
RAM Voltage = 1.8
SPP Voltage = 1.3
MCP Voltage = 1.5
HT SPP <-> MCP Voltage = 1.2
OK, the past couple of days I have been experimenting with trying to get my system to overclock higher.
I can say that whenever I try 1500QDR - 1599QDR the computer wont post.
When I try 1600QDR - 1710QDR the system will post and almost reach into Windows.
Now when I try 1711QDR and higher, the system will get into windows with the following voltages:
When you get bus speeds that high try increasing the FSB Termination a bit.
Part of your problem is that chipset as FSB holes. It just won't post at certain speeds, obviously you've run into that some. It's a quirky chipset with a Q6600 over 3.0 GHz.
So i take it that giving too much voltage may be a problem and I should try going up and down on each voltage settings?
Mostly up.. honestly reading through again I think vCore should be up to around 1.4ish or so. Give that a shot and see if it'll boot.
Sorry I'm a bit tired and wasn't thinking straight.. Basically you hit a FSB hole and haven't really increased vCore since 3.3 GHz. Moving up to 3.6+ GHz requires a lot more vCore and if it gets into Windows and just randomly restarts I'd try to bump the vCore.
My CPU personally needs 1.4vCore to get stable in Windows at 3.6 GHz. At 3.3 GHz it only needed something like 1.312. Basically the voltage needs go through the roof as you get that high.
