Exclamation Fatal Error

Hello, I'm new to Prime95, I downloaded this program to stress test my RAM. I have let it run overnight and thismorning worker #1, and worker #4 have stopped running, with a fatal error message.

Worker #1
FATAL ERROR: Rounding was 0.5, expected less than 0.4
Hardware failure detected, consult Stress.txt file.
Torture tes ran 51 minutes - 1 errors, 0 warnings.
Worker stopped.

Worker #4
FATAL ERROR: Rounding was 0.4990234375, expected less than 0.4
Hardware failure detected, consult Stress.txt file.
Torture tes ran 51 minutes - 1 errors, 0 warnings.
Worker stopped.

What does this mean? Are number 1 and 4 RAM sticks faulty / need to be replaced?

Because workers 1 & 4 had failures does not mean that the RAM sticks 1 & 4 are bad. You may have RAM, CPU, or cooling problems, or there are adjustments to be made to make your machine stable.

Is your machine brand new?
If so, you may want to return it for a new one. (Happened to me.)

Is it store bought or home built?
Can you describe the system, CPU, RAM, voltages, memry timings, etc. (Anything might help, but if you don't know, just say so.)
Is it overclocked? If you don't know the answer is likely, no.

Is the RAM new?

Have you tried Memtest86 or the new variant?
This will give you more info about bad RAM.

If it passes memtest and fails with Prime95, it may still be memory, but likely other things.


Others will be along to digest the results of your answers.

Red face Me again

Yeah my machine is about 8 months old! its a Dell XPS 630, running Vista 32bit, with 2 500GB 3.0G/s hard drives with native comm queuing, 4 GB (4x1GB) NECC dual channel DDR2 800MHz SDRAM memory, Intel Qore 2 Quad processor Q9450

Its a Dell XPS 630, 2.66GHz, 12MB L2 Cache, 1333MHz FSB, dual 500GB SATA 3.0GB/s Hard drive with native comm queuing, 4GB (4x1GB) NECC Dual channel DDR2 800MHz SDRAM memory, Intel Core 2 Quad Processor Q9450.

I will try the other programs sugested to se if it faults again! I still have a few months full cover on the machine! should i be ringing Dell to get it fixed? If so what should i tell them? "that i have ran a self diagnostic on the machine and some of the components have proved to be faulty?"

i hope that this information helps!

When you report the memtest results, someone here will have more interpretation.

When you do speak to Dell, try just going ahead and naming "prime95 torture test" as what you ran. Dell has heard of it by now, though the particular rep you speak to may not necessarily be familiar with it. Then you could tell them the interpretation we will give you after memtest.

(Intel has used prime95 as one of their standard tests for their CPU production lines for years. Various hardware reviewers of PCs casually refer to it in their articles. Though it isn't really a general diagnostic program, prime95 has long had a reputation for usefulness in exposing certain types of system weaknesses, so is well known by name to many folks who have reason to investigate/fix system faults.)
