What is considered a Prime95 failure

[warbean]

Hey all,

First time overclocking here, got an A64 3800+ (Single core Venice) paired with MSI K8N Neo4 Platinum, 2GB Corsair XMS DDR400 running at 2.5,3,3,7.

Vcore raised to 1.55v (1.425 * 1.099), memory at 2.7v.

This gives me final FSB of 220 and memory running at 440 because of a 200 divider, 2.64 final clock speed. (220 * 12)

Unfortunately, I am not Prime stable at this setup and want to know what's going on. Prime ran for 3 hours alst night before I went to bed; when I woke up it appears the whole system crashed as my computer was still on but the screen was totally blank. Needed to reset. The night before, when I woke up, the screen saver was on but frozen.

I was wondering what it means to fail Prime 95. Obviously this counts, but do most posters just refer to the software program noting afailure and then halting the test, rather than a huge lockup or crash?

I think the problem may be the memory, as it's not rated to run above 400, but memtest ran fine for 3 hours with this current setup.

Thoughts, anyone?

Prime just quits running and says an error occured and the icon in the toolbar turns from red to yellow.

your symptoms are considered a crash

It is most likely ram is whats holding you back, you probably need to
1. loosen the timings
2. increase the mem volts
3. use a memory divider

I would also recommend following Zebo's guide stickied at the top of this forum and test you CPU, HTT(FSB), and ram seperately

That 3800+ likely has more left in it

Ya, the major pain is figuring out how long Prime was able to run when I go to bed when it crashes like this.

I wish it would just fail the normal way like you described.

Test the RAM via MemTest.

Test the CPU via CPU Burn In.

That might help you localize the issue, since Prime95 is kind of a test a bit or alot of everything or one thing.
