Just noticed this option in the bios in my machine the other day.

Q6600 at stock + Akasa Evo Blue cooler.
Asus P5N32E Sli+
4GB Kingston DDR2 800Mhz

Tried 5%, ok, 10%, get the frequent TDR's in games. Tried 20%, windows wont even boot.

What other settings do I need to change to get the machine to boot at 20%? Been reading a few threads on here? I noticed that when I apply the Ai overclock option, CPU voltage does not change from 1.28 volts. Do I need to increase this to say 1.29? 1.3? I know you have to go up in baby steps but further help would be needed.

Loosen your ram timings first. set it at 5-5-5-15. Set the mem divider back to 1.20:1,1:1
On voltage, you can go up to 1.5 on that cpu.

Current timings:

tRAS 18
tRCD 6
tRP 6
tRC 24
tWR 5
tRRD 3
tRWT 5
tWTR 10
tRDRD 3
tWRWR 2

Which ones do I need to change? Not played around with ram timings before.

And set back the dividers so they run 667 instead of 800+ (400*2 )Mhz


So: only set the CAS (tCL):5
tRCD: RAS to CAS:5
tRP: 5
tRAS: 15
CR: 2

You can also read out your spd with everest. And modify it to the SPD, but thats not necessary.

Just gone back into the BIOS and couldn't find anything relating to ratios with AI overclock enabled. Set overclock options to Manual, and then I found an option 'FSB memory ratio' 1:1, 5:4 or 3:2, or sync mode. Also found FSB (QDR) and FSB memory clock mode.

Went tried a 20% AI overclock with the memory timings you suggested at the machine wouldn't boot. Set them back to auto.

CPU-Z says the core voltage is 1.216V, yet in the BIOS Vcore = 1.28. Which is more accurate?

Looks like the best option is to do it manually, except I am going to do a hell of alot of reading up on alot of it goes way over my head.

You can leave your memory at spd, but not sure if it will work during overclocking.
However, if you're doing a high overclock set your fsb memory ratio at 1:1.
Cpu-z tells different because there's a voltage drop on most motherboards, especially on load.
Pretty much both is accurate, you can still set your vcore higher up to 1.5.
