trying to run 200FSB

[alpha22555]

Okay I have an 8RDA+ and 2x256 meg Corsair xms 3500 and an xp 2200 CPU whenever I go to expert and set cpu freq to 200 mhz and use a muliplier of 9 to get 400mhz my system des not run stable at all if anyone has the exact same stuff that I have I would appreciate the settings you are using tks also I have memory setting to AUTO tks

The secret is to remove the jumper in between the northbridge and ATX power connector. This jumper tells the board the approx bus speed. This got me up to 200 MHz no problem, where as I crapped out at 194 beforehand. Anandtech couldn't get the board over 194 MHz either, but they didn't try this. The epox isn't the only board to suffer from this, a well know quality brand that has four letters and ends in "t" also has this problem.

I tried removing the jumper, but still stuck @ 194

Im running Corsair XMS 3200 and XP2400+. What voltages should i be looking at to get it to 200MHz??

I can get it rock solid @ 193*12, 1.8v. Temps are fine 35 idle, around 42 load.

TIA

Leave jumper off,

CPU set to optimal, 10-11 x 200 CPU thermal throttling disabled
RAM to 6,2,2,2.0 or 7,3,3,2.0 (if you want to play it safe).
memory voltage to 1.77 (corsair reccomend this) Leave CPU voltage as is. Set memory to SYNC or 100%. , agp at 66.

Try this out dude!

I presume your chip is unlocked if you are trying to run at 9x multiplier. First determine if your memory or cpu is holding you back i.e. underclock the cpu to 1.6Ghz (8x200) which it should easily manage at default voltage to see if your memory can run at 200Mhz. If the system is still unstable up the Dimm voltage untill stability is reached.
Now you can increase your cpu multiplyer to the desired speed and again check for stability. Increase cpu voltage untill you have achieved this keeping an eye on temp. If you are not overclocking then you shouldn't really have to do this but it won't harm the system.

As far as voltages are concerned I wouldn't go above 2.0 Volts for the cpu. At which you should get a decent overclock with good cooling
