Overclocking and V-Core Adjustment on the 8RGA - Questions..

[RickCathey]

After owning an Epox 8RGA for about 3 months now suited up with an AMD Barton 2500 and 512MB (2 sticks of 256) of Crucial 3200 memory I started reading about how users were easy overclocking the chip. Most stated they only changed the FSB to 200 and the multiplier to 10.5 which give them the same comparable speed of a Barton 3000 and the system was very stable with these settings. They also mentioned something about not having to adjust the V-Core any and being able to use the default of 1.65. I have my system set to show the status of the V-Core, CPU temps, etc. upon bootup and it is showing the V-Core running at 1.60 to 1.61. I looked in the BIOS on the same page where I changed the FSB and multiplier but saw no setting to adjust the V-Core. Where would I find the adjustment for the V-Core? Is it labeled as something else in the BIOS other than V-Core? I am running all this in a 4 year old Antec Tower case with their 300 watt p/s that came in it and it has performed flawlessly since it's been in use.

Also one other thing, after I changed to the faster settings the system worked great with the exception of the video display. The monitor would black out for about a couple of seconds but would come right back on. This would occur maybe two to three times every half hour. Sometimes there would be misc. garbage on the display after the blackout which could be cleared up with a screen refresh. I am using an older ASUS GeForce 3 card as my video adaptor. Do I need to change another BIOS setting regarding the AGP slot due to the overclocked settings for the CPU?

Thanks in advance for any suggestions

I have the 8rda+ which is a different board. But I think if you set the cpu setting to expert it "reveals" the options you want. Also set the memory settings to "user define."

That is how I remember things - too lazy to check, sorry.

Also set the cpu interface to aggressive (I haven't found any advantage to this but someone will say it so might as well be me)

Drop the multi low by about 2 full settings before you raise the fsb by 2 or 3 mhz at a time, bench it or otherwise use the computer each time. You're going to corrupt your bios otherwise (somehow I know this...)

You could start with a fsb jump of 5 at first and then slow down at the end.

When things seem unstable or degrade the benchmarks, upgrade the vcore at that setting and try again to see if the performance goes back up. Keep your eye on your temps but you know that.

If this is what you tried already, sorry
