:doh!:

I have new glasses on order... (I'm not joking.)

[QUOTE=chalsall;422080] How long have you let this test run for, [/QUOTE]

10+ hours (prime is still running) ...


[QUOTE=chalsall;422080] and what motherboard are you using?[/QUOTE]

ASRock Z170 OC Formula

Has the performance changed? The benchmark in Prime95 would be a good tool to use to see. Thanks!

But that only works against a baseline.

willmore, perhaps we could ask you to run a bunch of tests before the upgrade, and then run a bunch of tests after the upgrade, and see how they compare?

Sweet! I would give it 24 hours just to be sure, but it looks like you guys found a true bug that Intel took seriously.

As George said, kudos to you and your associates.

You guys found this bug; we were just the support crew. :smile:

MSI team don't send me a beta bios including the microcode but rather tell me to wait for the next bios release :down:

Would do me a favor and run the benchmark inside of Prime95 before and after? There are a lot of people curious if this fix will have a performance penalty. Too many bad memories from Barcelona.

chalsall, I wish I could run Sky Lake benchmarks! My newest box is Ivy Bridge. :(

It's chalsall. And if you can't run your own tests under Skylake then pay people to run the tests you want.

[QUOTE=chalsall;422080]Fantastic!!! :tu:

Two quick questions if I may... How long have you let this test run for, and what motherboard are you using?[/QUOTE]
More important question: do you see any performance hit when you run the "more stable" newer version? (like they waiting for threads sync internally, or so, to cheat the bug, etc)

I had that same idea:

But chalsall suggests I should buy my own SkyLake system to test:

Maybe we should pool our pennies?
