Newbie needs assistance with o'clocking

Hi,

I have corsair XMS2 (2 X 1GB) with 4-4-4-12 timings and an IC2D E4300 on a Gigabyte P965-DQ6 mobo. I have read that this memory is made to run at 2.1V but that Intel chipset based mobos run memory at 1.8V. In either case, I have set my cpu to 333 (gives 2997MHz) and left memory timings on auto and set memory voltage to +0.300V. CPU voltage is 1.3875 and the system is stable (Orthos, Memtest 86, etc.).
When I run this configuration, CPUZ reports memory timings of 5-5-5-15. Now that the system is stable, I decided to go back into the bios and set the memory timings to 4-4-4-12 but when I did that, the system became unstable (reboot during Orthos). Not knowing what I'm doing, I decided to try FSB voltage. The increments are in 0.05V so I tried 0.05, 0.10, 0.15 & 0.20 but it did not help.

Question is: where do I go from here? Do I leave the memory timings in auto (it irks me that I paid extra money for the faster memory only to run it slower) or is there something else I can tweak to get the system stable at the faster memory timings?

Thanks for the help!

try and set your ram ratio manully. what you want to do is keep close to stock speed so that you can run faster timings.

I had been doing my overclocking with the ram ratio set to 2.00 (1:1) but for the overclock mentioned here I have the ratio set to 2.66. I will try 2.00.

Thanks!

When you set the timings to 4-4-4-12 did you also set the voltage to 2.1?

My mobo does not state actual voltage but rather overvoltage. Assuming the voltage applied is 1.8V when overvoltage is 0.0, I set overvoltage to + 0.300V. Again, I assume this is 2.1V. When I set the multiplier to 2.00 (I believe this is 1:1), the stated memory frequency is 667 (with CPU set to 333) but this memory is supposedly good to 500+ (1066) so I tried 2.66 which gives me a frequency of 886. I will try the other memory multiplier settings this afternoon.
Also, do you know if 1.3875V is too high for my E4300? Intel states the voltage range for this CPU is 1.22 - 1.325 but 1.325 is the default (auto) voltage applied by my mobo.
I get temperatures under load of 70 with TAT but I've read that TAT reports high numbers. I am going to try RMClock this afternoon. I have a Scythe Ninja which seemed to be the best I could get to fit my mobo (can't use HSF with bracket on the back due to Gigabytes "crazy cool" heatsink on the back of the mobo).
