Corsair XMS 3200 2.1

I got this running stable at 157 fsb cas 2-3-3-6, DDR 418. It's logic that with relaxed settings, I should be able to get more out of the ram. If I up the fsb to 158, DDR 421, I get errors when running Memtest. So I lover the cas settings to 2,5-3-3-7, but I still get errors in Memtest. Weird, huh? My thought is that running stable with DDR 418 cas 2, it should atleast do DDR 421 with cas 2,5... But over 157 fsb I seem to get errors regardless of what timings I use.

Well I'm kinda lost here, but this ram must be great running DDR 418 stable at cas 2. Could it be the Northbridge getting too warm higher than 157 fsb, resulting in errors in memtest? Well I dunno. Any tip or hint is greatly appreciated!! :)

On a kx7/xp1700 system, my Corsair 512mb pc3200c2.5 runs 24/7 at 200 cas2 2-6-3 2T, if I relax the setting the most I can get is 205 unstable! It also will only run at 1T below 175 :rolleyes:

Burn the memory in at 1.85volts with Sandra memory bench.. SO just run the burn-in program for it and only select the mem test... Let it run a few hours.. I let mine run for 10-12 hours.

At the time my older or the 2 sticks wouldnt do cas2.5 at 200 then after it would do Cas2 as high as i could boot heheh.. So try it.

I've noticed that the chipset is to blame for me getting screen tearing at 205 and above.. Though i can get the system to boot at 215 into windows with much artifacts on the screen i cant run any 3d or 32bit color gaming.

I like theres some damn prob with the power between the Dram and the AGP.. They share power which is stupid.

So point is.. burn it in and be happy.. that ram will take you farther then this chipset the KT333 will allow you 2 run.
