Stuck on OC

post #1 of 9
Thread Starter 
Well I finally decided to overclock my e6600 but on stock voltage it will only let me get to about 2.55 (from 2.4 originally) before it locks up when I reboot. I can't get any higher and I'm running TAT for a while and my temps max out at about 54*C. Any idea? Should I try upping my vcore just a hair?

Also, is I'm confused about RAM timings. I have it set on Auto right now (I adjust the FBS and it automatically detects the ratio from FSB to Memory.)

It gives me the option of 1:1, 5:4, and 3:2. When I tried 1:1 it hung up on the restart. Should I just leave it at auto? What exactly do those ratios mean? Thanks!

What is your vCore set to now?
Which Coolermaster heatsink/fan are you using?
Set your ram timings to 5-5-5-15 @ 2.0v, and set your ram at the lowest divider possible for now (DDR2-533 when the FSB is 266). Then raise your FSB to 300 and try to boot.

There is my fan. It is doing a pretty decent job so far (I'm also using AS5)

Why would I want to set my ram timings to that?

My Vcore is 1.31

Setting your ram timings that loose eliminates the possibility that your ram is holding you back from your desired clock speeds.

Is it bad to have such loose timings?

you just need to loosen your timings while you are OCing your cpu. once you reach the limit on your cpu, then you can tighten your timings. also 1:1 is best, if possible

What to you take into consideration when tightening your timings after an OC?

Usually I'd make a bootable CD with Memtest86+ on it, and set in my BIOS for the cd drive to be the first boot option. Load the BIOS, tighten one timing at a time, run memtest. Rinse and repeat until Memtest fails, loosen one, and go on to the next timing.
