Hey guys,

I have been trying to overclock my new desktop for about a month, but never made it yet. It's kind of frustrating.



Below is what I have

- vist ultimate 64

- Q6600 (g0 stepping)

- gigabyte ga-x48-dq6

- g.skill ddr2-1000 (cl5-pq) 8gb (2gb x 4)

- diamond 3870x2 1gb

- raptor 150gb

- 850w power




And this is what I set up on the bios

- eist, c1e, cia2 : off

- cpu clock ration : 9x

- cpu host clock control : enabled

- cpu host frequency : 333

- pci express frequency : 100

- system memory multiplier : 3.00A -> to set memory frequency : 1000(from Gskill user's manual)



- dram timing selectable : manual

- cas : 5

- dram ras# to cas# delay : 5

- dram ras# precharge : 5

- precharge delay : 15

- command rate : 2T



- system voltage control : manual

- ddr2 overvoltage control : +0.25v (from Gskill user's manual)

- fsb overvoltage control : +0.25v

- mch overvoltage control : +0.25v

- cpu voltage : 1.5v





Funny thing is that my machine does not boot up when I put 100mhz in 'pci-e frequency'. And also when I set 'cpu host clock control' enabled, whatever value I put in the 'cpu host frequency' tab, it is not bootable. Because of these two things, I cannot do anything about overclock. Please help me out!!!

Set your memory multiplier to 2. Leave the memory settings including memory voltage to manufacture's recommended settings.
Set your vcore to 1.4 V at 3. G. ( it is a high vcore for 3 g, but it is ok to start from there) At that vcore , i expect solid oc.

Run prime test for 1 hour first. if it is stable, increase the cpu frequency to 3.2 g without changing vcore. then run the test again for 1 hour. If it fails, reduce it to 3.1 g. then run the test.Let me know after that.

Thank you for your comment.

However, it never boots up when I set 'cpu host clock control' enabled. which means 1.4v vcore or whatever is not going to work.
