This is my first overclock and it is being a pain.

I can get 240 x 12.5 without problem and at stock volts; however, this overclocks my RAM from 800 MHz to 960 MHz. This is with the memory divider set to auto. If I try FSB 241, it does not boot. I know this is the memory that can not be overclocked more.
Here is the big problem, if i change the memory divider to 2.66 or 3.33 with FSB 240 it does not boot.
With the memory divider at 2.66 it only boots up to FSB 202 and with divider at 3.33 it only boots up to FSB 208.

The funny thing is that it does not boot with FSB 240 and memory divider set to 2.66, but I tried FSB 250 ind it booted great. I think it is because that makes the memory run at 667MHz. So I tried 250 x 12.5 at stock volts and it worked fine for a week. Run prime for 5 hours and it didn't pass 54 degrees (using stock cooler). One day it decided not to boot. Then I raised the volts to 1.3 and it worked good another week. Now I have it running at default speed because I don't want to give so much volts to the cpu for this little overclock. Any recomendation will be greatly appreciated. I want to say that if I try FSB 249 or FSB 251 it does not boot.

I just want to hit 300 x 10 or maybe 300 x 10.5 until I get a better cooling solution.

My BIOS is F8(Last one) My PSU Antec Earth Watts 380.

My memory http://www.newegg.com/Product/Product.aspx?Item=N82E16820145241

Any help will be greatly appreciated.


Thanks in advance.

With this board you will want to keep your memory/fsb @ 1:1. I believe it limits your FSB options in the bios though.

This board is not the most OC friendly board out there. I read a few reviews and it seems hit and miss with the majority missing. I would find a stable ( modest ) configuration and go with another board when funds are available.

According to my math, 240x12.5 = 300x10. Am I missing something?

Without knowing what your ram is, the problem is probably your G31 board. They aren't known for overclocking. I doubt its your ram, if it is you can simply loosen the timings some. Bump them down to 5-5-5-18 and you should be alright. (might need to up the memory voltage.)

This board doesn't let me to set FSB/RAM 1:1. The lowest divider it has is 2.66.

This is my RAM: CORSAIR XMS2 4GB (2 x 2GB) 240-Pin DDR2 SDRAM DDR2 800 (PC2 6400)
I will try bumping the voltage to see what happen. Although I don't see why I should bump voltage if I am not overclocking the RAM.
