If I set my HTT to 250, and have my Ram at 333. It will have instability issues. It's bugging me.

So exactly what settings should I change in my BIOS? I'm asking you, C38368, because you have the same motherboard and CPU as me.

Maybe I'm changing all the wrong things...?

I have PC3200 installed, and the BIOS is set to DDR400. I've set the HTT up to 256MHz, and I'm currently running at an effective DDR512.

Why do you set it to DDR333?

I heard that DDR333 placed it into a divider....

At the moment. I have HTT 230 x 4, and my Ram set to DDR400 which gives me DDR460 correct?

Whenver I go over DDR500 (HTT 250 or above). It doesn't like it, and I fail minutes into a Prime95 torture test.

Any ideas?

Don't know if its been mentioned before but have you tried with just 1 stick of ram to help with stability and also made sure that you have it on 2T not 1T,if you have that setting?

It is on 2T. But I haven't tried 1 stick. I'm not too sure it would help much.

Make sure you're feeding it the proper amount of voltage.

The sticks you have are rated at DDR500 with a 1T command rate. Put the HTT at 250MHz and lower the CPU multiplier by two. See if it changes the failures in Prime.

The sticks are running at 2.8v. That should easily be enough.

They refuse to work at 1T. It booted windows, but my tasbar failed to load up, and it just froze (I could move the mouse, but nothing else would load). So I put it back to 2T.

Ram is fine at 500 with CPU Multi at 10X and HTT at 250MHz.

But when I put the CPU Multi at 11X, it hates me. :confused:

Should I try 10.5X and see how it reacts?

Yes. You appear to have a lousy CPU.

What voltage is your RAM rated at?

2.75v

Lousy CPU, as in.... I have a lemon? Or the whole 3700+ range was lousy at overclocking.

As in you have a lemon.

Lower the Vdimm to 2.75V and tell me what it does, at 1T.
