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! Thanks, Wayne |

Your words are prophetic, this morning I thought I had fried my system
completely... turns out there was a problem with the PCU to HD connector so I'm up and running so I guess I'll leave well enough alone. I did manage to set my memory timings to 2-2-2-5 however. :-) Wayne "philo" wrote in message ... snip reducing the memory timings?

I have never damaged memory or CPU by overclocking. The worst that can happen is that the system won't boot. Just clear the CMOS. I currently have taken an XP1700 B core and PC2100 from stock 133x11=1463 to 145x12.5=1812 with no fuss. Memory is maxed out but CPU is probably far from its top end. It'll run Prime95 all day in a hot room at standard V-core. Performance increase is indeed noticeable. We're only talking about a $45 chip, folks. |
