Athlon64 3000+ unstable at 215x10?

[byrn]

I was hoping to hit atleast 220, and I had read that 220+ was very common, specially with a PCI/AGP lock board (AOpen's). My build is:

AOpen AK86-L
Athlon64 3000+
Mushkin PC3500 512mb (Level One, 2-3-3)

The motherboard keeps the memory locked at DDR400 (I wish I was able to actually use it at DDR433) and PCI/AGP locked at 33/66.

I recieve Prime95 errors at 215 and above, I will try bumping up the voltage now. I'de also like to know if bumping up the memory voltage would help at all.

Should I just asume that I got an unlucky draw at the CPU?

i don't think your ram is locked at 200fsb. my board has a similar setting but when you raise the fsb the memory goes with it. these are basically your dividers. 400 is 1:1 333 is 5:4 266 is 3:2.

Ok, I'll try that.

When I set it to DDR400 I can see the multiplier dropping, it shows DDR400 as 215x1.82 or such, if I raise the FSB it will drop the multiplier.

Anyway to test this? Sandra's memory benchmark?

It just says DDR400. It's lying. ;)

You can use a program called CPU-Z to check the actual memory frequency. It's fairly easy to find - Google it and it should be the first hit (or near the top).

Also, I would suggest doing as Maxvla said: change it to DDR333. Although it'll give you less performance, your board may not like working with you RAM. I found that my K8N didn't like playing with CH-5, and that may be the case with your board.
