Overclocking sucess XP 2500+ Barton on ASRock K7S8XE V3.0

Hi,

just for information:
AMD XP2500+ Barton (166 MHz fsb) runs here with fsb 200 on the new ASRock
K7S8XE V3.0 prime95 stable for hours without rising up the vcore: 2,2 GHz
physical clock. Related to AMDs p-rating it should be around XP3200+. The
cpu stepping is AQZEA.RAM: MDT PC3200, 512 MB, CL 2,5. The cpu temperature
under load is 53°C only (room 21°C). The cooler is a Arctic Copper Silent
pro 2 TC.

Next days I will try to increase the multi from 11 to 12.

So far it's a fantastic cpu, I got the last one with this stepping from my
dealer :-)

Bye

| without rising up the vcore

AMD's default Vcore`s seem always unnecessarily high : my K6III400
& D750's 2.4 & 1.6v are enough for 460 & 825mhz : [i] waste
electricity & aircon bill [ii] produce useless & dreadful ( *esp in hot
climate ) heat for users who don't OC [iii] the excess heat slow cpu &
n-bridge [iv] reduce maximum ambient tmprtre acceptable*, life of cpu
& n-bridge, own popularity* & sales.

Did it yesterday:

206 MHz fsb, 11x , Vcore at default & +5%, -> didn't boot
200 MHz fsb, 11,5x, Vcore at default -> hangs during boot
200 MHz fsb, 11,5x, Vcore +5% -> is running, but not stable in prime95
200 MHz fsb, 12x, Vcore +5% -> didn't boot
202 MHz fsb, 11x, Vcore at default -> runs prime stable, and so I will let
it work. This corresponds to a p-rating of XP 3220+ (regarding Central Brain
Identifier).

I could surely try to lower the fsb to get the chance for higher the multi,
but for me the fsb has first priority to improve the bottleneck between cpu
& ram.

The K7S8XE does not supports to adjust the voltage by a certain value, there
is just only one option in the bios to increase the vcore by 5%.

One piece of wire in the socket will get you 1.85v + 5% (if you want it),
almost 1.95v.

Thanks for your suggestion, but I decided to live with 200x11 until I really
need more power. My system is rather fast now and with 53°C acceptable warm,
in spite of air cooling. I will enjoy it for a while ;-)

3200rating is nice, I have mine running like that at 1.75vcore. But in
sandra it compares to a 2700xp TB cpu.
