my 2500 barton cant break 200 fsb. at 205, programs crash. it shuldnt be temps, because the proc. idles at about 37c, 43c at load. Ram is pc3500 hyperx 512x2. Ram shouldn't be holding me back, unless its a dud stick. any ideas? vcore is 1.75. i can prime at ddr200, havnt had time to prime above that. doubt its ram tho....maybe. any ideas appreciated.

You have to ISOLATE the other factors to see what is really holding you back.

First what type of mobo are you using, Nforce2?, Kt400, Kt600

Try loosening your timings and the ram and upping the ddr ram voltage.

Try raising your vdd voltage "Motherboard voltage", most Nforce 2 boards need a little boost to go over 200

The key is to isolate each factor, Chip, mobo, ram to find what is the weekest link.

By isolating each factor you can find out what the max is for each part of your system.

Let us know, were all here to help but we need more information to help you.

well, nforce2 ultra ("official" 400fsb compatibility) a7n8x mobo. ill try the vdd voltage. if not that, then loosening timings. but its pc3500 rated at 2-3-3-7, so it should be able to run those timings at ddr 205.

In order to run my Bh-5, which is the same memory as yours, I have to use 2.77V to hit 210 cas 2, 7,3,3. I can hit 217 at 2.9V

My Barton 2500 is currently at 2450 with 2.025V, try raising your CPU core voltage a little, LOWER your multiplier to 10 so you can really see how fast of a fsb you can run on it . You can raise is later.

I wouldn't raise your voltage past 1.85V unless use have EXCELLENT cooling.
