Take the trouble to prove "well within specs" by running the "GIMPS Torture Test". Easily done and it could save you wasting many hours.

You don't know if the FPU is good or just producing fast garbage.

A CPU can be stressed such that you do not see any system crashes whilst the FPU timings fail and produce 'unseen' numerical errors.

Run the GIMPS program, select Torture Test, and you are then running some very intensive /calculations/ with *checksums* that test if your FPU is good under those conditions.

To not do so, you might be just calculating expensive wothless garbage and you will not know.


Diagnostics are useful.

Good luck,
