First Overclocking Experiments with EP-8RGA+. Advice welcome.
Sorry to cross post; this ended up in the wrong newsgroup.
I have a AMD Athelon XP 2400+ on an EP-8RGA+ board with Kingston PC2700 RAM
(2 x 256).
When I first assembled the machine I set FBS = 166 and dropped the
multiplier from 14.5 to 11.5 as suggested by Bas Ruiter here to avoid
overclocking of the processor. Got the system up and running beautifully.
Next, with stock voltage (core CPU 1.65) I raised the multiplier cautiously
to 12.5 withoug difficulty. But at a multiplier of 13 the system crashed.
Even at 12.5 the processor was getting a little
hot ... mid 50's C. So I upgraded to a Vantec Aeroflow, and installed a case
fan control unit to bring the processor below 50 C.
By gradually increasing core voltage from 1.65 to 1.75 I have been able to
bring the multiplier up to 13.5, but the system reboots while trying to load
WinXP at 14.0.
I have not tried changing memory timings or vdd which is possible with the
bios. My goal is to reach a multiplier of 14.5 at FBS 166. Should I just
keep pushing vcore or make some other adjustments? What are the pros/cons of
reducing the memory timings? I am being rather cautious because I don't want
to distroy my first homebuilt computer!
