Hello, I followed these exact instructions to OC my e6600:

to OC this board easily: Here is an example using a e6600 CPU. With DDR2 800 memory at 5,5,5,15 Make sure these 6 things are DISABLED in Bios - CPU Enhanced Halt (C1E) - CPU Thermal Monitor 2(TM2) - CPU EIST Function -No-execute memory protect -Limit CPUID Max to 3 -Virtualization Technology - Set Voltage Control set to manual. - bump Vcore to 1.4 < if needed - Set Clock Multipler to 8 down from 9 - Set CPU Host Clock Control to Enabled - Set CPU Host Frequency (MHz) to 400 - Set PCI Express Frequency(MHz) to 100 - Set System Memory Multiplier to 2.00 - Set DRAM Timing Selectable to Manual - Set CAS Latency Time to 5 - Set DRAM RAS# to CAS# Delay to 5 - Set DRAM RAS# Precharge to 5 - Set Precharge dealy (tRAS) to 15 The CPU then boots at a very nice 3.2 GHz.

And it booted just like it said, 3.2GHz. I did a stress test with TAT and when the heat got up to around 51 computer rebooted. Is this a common problem? What should I do? Raise my vcore?

you have a 9x multi USE IT

also what are your specs???

board
ram
etc....

Hi, thanks for the replies, CPU e6600 mobo is gigabyte 965p-DS3 rev 3 geforce 8600GTS (i know, stepping up to 8800 soon) zalman 9700 heatsink and a 500 watt atx PSU memory CORSAIR XMS2 2GB (240-Pin DDR2 SDRAM DDR2 800) and an evercool NB cooler . Its my first build and im looking to get the most out of it!


What is it set at now?

I reset the bios and running it on stock settings.


you have a 9x multi USE IT

I dont really know much about OCing so i decided to follow these instructions... looked easy enough. I didnt want to do anything else besides what was on the instructions, i didnt want to break anything :eek:

So, do I need to add more voltage to VCORE? If so how much? Or maybe a better PSU? Help would be much appreciated.

A few things.

Yes - you might need to bump up your Vcore a little - I had to bump mine up to get 3.2GHz...

Also, set your RAM Vdimm Voltage manually in BIOS (set it to whatever the RAM is rated at).

Dropping the CPU Multi to 8x also affects other settings on a 965 based MoBo (at least it does on Asus boards, I'm not 100% sure about Gigabyte - but I'd assume this is reliant on the Chipset and not the BIOS/Board itself). You end up runing the RAM (and Northbridge) FASTER than you think you are. If your Gigabyte is like an Asus in this respect, you are actually runing your RAM at 850MHz due to the dropped CPU Multiplier...

Crank the Multi back up to the "Stock 9x" setting, and lower your FSB to 355MHz - that will retain your 3.2GHz, but run your RAM slower. Try to stress test again - if you are stable - it is likely a RAM issue (RAM was running too fast with a 8x multi). If you still crash at 9x, then the CPU might be your bottleneck since the RAM is running at or below rated speed. Try more Vcore (just not too much)...

PS - SiSoft's Sandra is the only application I have seen that properly reports "True" RAM and Northbridge speeds when lowering the CPU Multi on a 965 based MoBo...

I'd also assume you have tested your RAM at stock speeds with Memtest86a?

Once you play with it for awhile, and read some more posts, it will all start to "click"...

:cool:

Is it an auto reboot sans a blue screen (assuming you have auto restart on system failure unchecked in your OS.)

BTW: Post your complete system specs if you want the best possible advice.
