For some reason I seem to have hit a wall of stability at 211MHz FSB, after overclocking my Athlon 64 2800+. If I go above that, BSOD's often occur after random periods of time. I don't think this is due to overheating, but I could be wrong.

My CPU Heatsink/Fan Combo:

Except, mine has blue LEDs ;D

After running a stability test via SysTool while the FSB is above 211MHx, errors tend to occur. As I understand this isn't much of an overclock. The only thing I can think of that could cause this is my low speed, budget, no name, RAM. If that isn't the case should I supply slightly more voltage to the CPU?

Obviously I don't have much Overclocking Experience :-\

What should I do to increase the stability at higher OverClocks?

Specs in sig...

Nope, that's a shocking overclock. I doubt it has anything to do with heat.

Most likely, it's due to that fantastic PSU you own, or as you say, RAM. Overclocking is all about identifying system weaknesses and either eliminating them or working around them.

Don't be quick to blame the RAM however - some RAM can be really affordable and yet, fairly good in quality. Take Hynix DT (especially DT-D43) Select modules of that will run DDR500 or DDR400 at 2-2-3-5. Take a good look at your modules and punch the manufacturer and model code into google. The manufacturer should have the specifications listed.

You will probably need to relax your memory timings. I recall that Samsung TCCD modules could only run CAS 2.5 up to about 210 MHz on most systems, but could reach 250 MHz easy enough on CAS 3.

Alternatively, relax the divider/ratio. For example, on a 5:4 ratio, you'll be able to get your stock standard fail-safe DDR400 with a FSB of 250 MHz FSB on a 5:4 ratio. This'd equate to 2250 MHz core, or an Athlon 64 3200+, which'd be a decent boost even if you didn't gain any memory bandwidth.

Well, I will be replacing my PowerSupply, as I stated in the other post. Unfortunately I cannot get any specifications for my OEM Ram because the manufacturer seems to be non-existant. The only logo on the chips is LD. The closest things I found about my ram are these and I don't know what to make of it:

• http://hikaru.client.jp/memory/3200/0068.htm
• http://hikaru.client.jp/memory/3200/0076.htm

Since this "LD" company doesn't seem to exist I will conclude that this ram is from pirated schematics and was produced by some underground organization :P. Just Kidding.

It's probably acid washed and remarked. Common practice.

Just try slackening off your CAS (remember, higher numbers mean slower response/slacker timings).

Thanks Syphus, I'll do that.

Syphus...you're a genius! Relaxing the timings did the trick. I can run the FSB at 237.68MHz without the slightest instability issue! This is a lot better than 211MHz! I'll continue to Overclock to ~250MHz, but this is a start.

250 MHz is fairly ambitious to be honest, but good luck.

PS - that's not genius, it's elementry overclocking theory.
