BSODs have reduced but still happening.

I'm running Prime95 using the Blend tests. After 3.5 hours one of the 'workers' errored with the following

FATAL ERROR: Rounding was 0.5, expected less than 0.4
Hardware failure detected, consult stress.txt file.


Any idea what this indicates?

Thanks
This means that a hardware fault was detected in your CPU, you should replace it.

Happy New Year!

My quest goes on. I don't think its the CPU but I suspect the memory. Could someone please take a look at the last three mini dump files and performance analysis I have attached and see if they throw any more light on this really frustrating situation!

Thanks again for all your valued contributions.

Solved: Prime 95: FATAL ERROR: Rounding was 0.5, expected less than 0.4 - PC Help Forum
It was a MB case with the same issue. It is better to have a second test like MemTest86 for several hours and try swapping memory sticks or removing some of them. Check the voltages too.
Prime95 FATAL ERROR Rounding Question
this thread is very interesting too. Maybe you need to increase the vcore voltage (cpu voltage).

Thanks for that. Interestingly the second issue was a bad motherboard. As I'm not o/c on a frsh install I'm sure it's got to be RAM, CPU or m/b. Just not sure which due to most tests passing OK such as memtest.

As I can't test m/b by using other components (all my old components are not comaptable with new board) I'm going to RMA the RAM as a starter to see if that helps! If not I'll return\replace the m/b. Hopefully I'll get lucky

Replaced the RAM and the system is now running sweet as a nut!

Thanks for all the advice.
