Okay here my little journey on Overclocking my AMD Athlon Xp 2600+ with a Volcano 11 Fan NOT stock HSF

first the stock speed 166 X 12.5

Then I set the Multiplier to 10 and the Bus speed to 200

Then I set the Multiplier to 11 and the Bus speed to 200

Then I set the Multiplier to 11.5 and the Bus speed to 200

the BUS speed would NOT boot even at 201 MHZ at 11.5
and at 200 X 12.0 No boot

Are you Prime stable at that speed?

I run all day at 2.3 GHZ (200 x 11.5) but I need more voltage to be application stable, My BIOS voltage is set to 1.725 V but Vcore actually measures between 1.75 and 1.8 volts going by MBM.

I am never Prime stable, even at stock speed.

I have booted even at 200 x 12, but at 1.775 volts which is on the edge of my cooling equipment's capabilities, maybe a little beyond them.

considering you only have DDR333 then achieving 200FSB is no mean feat, depending on cooling 2.3Ghz could be your limit for this cpu

I had a set of two 256 MB PC2100 DIMMs that went to 215 FSB at 3-4-4-8 timings and all the voltage the board gave it.

Yes. PC2100.

My 'new' PC3200 only does 210 FSB, no further relaxing of timings or voltage helps.

yes IO think the slower ram has some added benifits maybe it slow the bus speed down after going through the slower ram, I dunno?

No, it's about the quality of RAM, not the rating.

I have A7N8X-E DELUXE BIOS rev 1013 with Athlon Thoroughbred XP2600+(original 12.5X166 1.65v)
11X202(2222) at 1.7v 50 celsius in full load ( Thermalright SI97)
at 11X204 is Prime stable at 1.75v but i have 57 celsius in full load
at11.5X200 its unstable even at 1.8v
