o/c 2.8c

[lego1]

My setup
mobo-p4c800-e
cpu-2.8c
memory-corsair xms-3200ll--2-3-2-5 1:1 voltage of 2.75

My max o/c i can get is 10 %=220 fsb

If I relax the timing can I increase my fsb.i would like to keep the 1:1 ratio.or is my ram at the limit.My ram is version 1.1 which use the bh5.any suggestions.

you may have play around with the cpu:mem ratio if you want to acheive a higher clock speed.

have you tried increasing voltage? my old 2.8 does 3.4 stable at air.

10% is about right for a 1:1 with memory rated as PC3200.

I'd say, keep the PC3200 and go with 5:4.

There really is no way around keeping 1:1 unless you go for PC3700 and faster.

relax the timings and see if you can get the memory to a higher speed

I have same board and processor. Different RAM though.

You appear to be using the AI overclock feature. Change this back to normal setting and then start using the manual settings, instead. Start by setting your ram to 2.8vdimm and ratio to 5:4 before you increase the fsb. You will be able to find your max fsb that is available for your 2.8C using these settings.

Are you running a 1:1 ratio

I am running 1:1 using PC4000 but I ran 5:4 for quite some time using
Kingston HyperX PC3500 BH5 chips. There was almost no performance
gain when I went to 1:1, since the timings were more relaxed on the PC4000.
You can see my rigs in my signature.
