I am looking to overclock my sig. to around 2.5 GHz - keeping the CPU/RAM at 1:1 ratio giving me and overclock of 250 MHz on the ram.
At the moment i can get up to 2.6 GHz stable - however i am at the moment at 2.5 GHz with the ram at CPU/12 giving a ram speed of 208 MHz - which is not what im after (i also heard that ram needs to run at the same frequency as the cpu to get better performance)
If i try and set my divider up to 1:1 i can get a stable 2.34GHz with 234MHz memory but anymore than that either wont boot or is unstable.
I have looked at this website and tried to copy the steps that they have done to get what im after http://www.legitreviews.com/article/229/2/ 2.52GHz and 252MHz. I tried to copy the memory timings etc... but could only get to around the 220 to 230 mark before not posting. But when in windows i get crashes - whihc i think is the memory timings perhaps.
My BIOS has these options.
CPU clock multiplier
CPU vid control
HT clock multiplier
CPU frequency (fsb)
Mem clock index value (this controls the divider ratio im pretty sure)
DRAM config
PCIE freq
CPU Vcore
VDIMM woltage.
Inside DRAM config i have
CAS latency (TCL)
MIN RAS active time (tras)
RAS to CAS delay (Trcd)
Row precharge time (trp)
Row to row delay (Trrd)
1t/2T memory timing.
Can anyone suggest what i could try to get a stable overclock of 2.5GHz and 250 MHz.
At the moment i have the CPU frequency at 250, the HT link at 3x, cpu/12 ratio, a slight increase in voltages and auto for all of the DRAM configs.
Like i said i can get 2.34GHz and 234 MHz stable on auto mem timings - but i cant get it much further than that on cpu/RAM ratio.
Thank you for any help
