Stability issues, where to start ??

Hi all !

I´ve been doing some OCing to my Q6600. I´ve pretty much used a "template" I´ve created using all the info I´ve read about similar setups. The sistem boots, its OK at idle (hotter than before of course), but I get errors when running prime95. I might even get a blue screen when running two or more times...

Since I´ve used settings I´ve "borrowed" from other people I don´t really know where I should start increasing voltages (if I have to...). Any suggestions ??

Here is my sistem running prime95 (and sistem info):

I forgot to include realtemp temps on the screenshot, but its 63-65ºC on all 4 cores (its actually realtemp the only temps app I´ve calibrated a bit). Room temp is 25-26.

Here are my BIOS settings:

AI Overclock tuner: Manual
CPU Ratio Setting: 8
FSB Strap to North Bridge: AUTO
FSB Frequency: 400
PCI-E Frequency: 100
DRAM Frequency: 800
DRAM CLK Skew on Channel A1: AUTO
DRAM CLK Skew on Channel A2: AUTO
DRAM CLK Skew on Channel B1: AUTO
DRAM CLK Skew on Channel B2: AUTO
DRAM Timing Control: Manual

1st Information:
CAS# Latency: 4
DRAM RAS# to CAS# Delay: 4
DRAM RAS# Precharge: 4
DRAM RAS# Activate to Precharge: 12

Any comments are welcome. Thanks for reading !

Thanks richardscott.

I was using 8x since I felt like 3,2 GHz was enough ! I dont want more heat, or at least rise it as little as possible, cos I think this is already quite hot (so I wanted to rise voltages as little as possible too). My goal was to be able to run the memory on 1:1 and with 400Mhz FSB

Thanks again ! I dont think I´ll go that high :p but I´ll keep it in mind. Regarding the temps/cooler issue.. I guess there is no other answer
