Prime & Memtest running oddly in new system

I ran Memtest86+ ver. 1.27 right after I put together the following system:

-P4P800-SE
-Prescott 3.2e
-Crucial cas3 direct from Crucial
-ATI 9800 pro

First off, Memtest tells me my 200mhz, DDR400 ram is running at 199mhz, DDR398. Then the test takes two minutes longer to complete a single pass than does my AMD 2500+ when testing with the same ram. The "Wall Clock" also does a far bit more jumping around (three to ten second gaps before reporting).

I did get a memory error when testing the ram on the AMD system after 30 passes, on test 5. I tried them one stick at a time, then together with 50+ passes and no errors. I also exchanged the motherboard.

Now I've tried Prime95, and it sticks at the first test and doesn't go any further. There is some suggesting in the video forum that it might be a confilct with the ATI drivers, but I don't know how else to test if the problem is with the ram (or even if there is a problem). I don't find the Memtest method reliable (the earlier version 3.2 won't even boot in this system).

One more issue, I tried turning on "Turbo mode" and the computer wouldn't boot. I thought that was pretty basic. Should I be looking at ditching the Crucials next?



 
By "stick", you mean it does not continue to run p95 and does not report error message? If so, I beleive this is a known problem, try to download a newer version. I could be wrong though ..

Memtest86, in my opinion, would not (or take too long a time before it detetcts) some errors.

P4p800: mine would not boot at all under certain memory configurations in BIOS -- no matter what stick(s) I put in. Very odd but I have accept the strange behavior since it does run 100% stabe under other configurations. Only my 2 cents though.

 
By stick I mean it starts but never goes to the end of the first test. I've used the latest Prime95 from their website. I did get it going in Windows XP safe mode. Must be a conflict, probably with the ATI drivers.

The point I'm trying to make about Memtest is that it worked faster (and smoothly) on my slower AMD 2500+ machine than it did on my Pentium 3.2ghz machine. I thought there was something wrong with the motherboard. By "configuration" do you mean the actual memory sticks you used? I did find that my Mushkin's wouldnt' even let the computer boot. I'm wondering if I should return the Crucials and get something else, any recommendations for this board, anyone?
