Comprehensive and reliable guide for overclocking RAM - Page 2

post #11 of 14
I'm asking for things like:

Vcore:
DRAM:
VCCIO:
CPU PLL:
Core Ratio:
BCLK:

If they wont work with those timings as 4 x 2GB, then using timings like 7-8-7-24 or 8-8-8-24 might be needed. I think that 4 x 2GB should be able to get that tight with a bit of tinkering though.

Is your 2500k overclocked?

Here are my UEFI settings right now:









Just started overclocking the CPU and kept my RAM to 1333MHz and Auto timings as of now. I can boot with 8-8-8-24 1T though. What do you think?

I would follow this guide for overclocking your CPU:

http://www.overclock.net/intel-cpus/...king-tips.html

Once the CPU is overclocked and stable, I would then go back to the RAM. If your RAM is rated to run at 1600MHz (6-8-6-24 2T) @ 1.5v, I would set it at that and slowly increase VCCIO an increment at a time to see if it makes a difference. Stress test as you go and don't go over 1.2v for 24/7 use. Eventually you will find a stable setting and it the VCCIO should be between 1.5-1.15v I reckon.

Thanks for the link.

As TwoCables said, those timings are rated for one kit (2x2GB modules). Pairing these two modules with another kit (2x2GB again) would not let your system run at stock timings. This is very logical because you can never find a 2x4GB kit that's rated CAS6 with just 1.5V of voltage. Besides, I already tried running my system at CAS6 1.65V and with a VCCIO of 1.2V and it still won't POST.
