How many threads in ibt

setter · 5 Jan 2010 at 22:01

Im trying to get my i7 overclock sorted again, using the latest version of intel burn test (ver 2.4), on the previous version there was a bug with 8 threads selected, so 16 had to be ran. Is it ok to select 8 in this latest build.

Ran ibt firstly on 8 threads selected, failed on the start of the 3rd test, selected 16 threads and let it run for 20 passes, max stress. Completed without errors.

Also left real temp i7 turbo 6.95 running to check for turbo throttling (which p6t dlx v2 boards are renowned for), thankfully throttling wasnt the case.

Seems to be ok now. At least it crashes as often with 8 as with 16 for me, so I'm just leaving it on auto. ymmv

edit: as clearly it did. Don't know what to make of that, sorry mate. LinX/prime next?

That's the same (low) gflops I'm getting, what's your ram set to? Other people are quoting 52 gflops at 4ghz, Im wondering if running 1200mhz cl9 is why mine is worse.

Hopefully as stable (as can be guaranteed) jon, ill give it my usual p95 small fft and blend runs over the next few days just to be sure.

With 8 threads selected i was hitting 52gflops, ram is ocz reaper running 1547mhz 7-7-7-24 1T, 1.64 vdimm.

EDIT: This failed on the second test. 52gflops ver 2.4 i ran a few days ago.

Decided to give LinX a run to see how it performs,

GFlops reading is higher than ibt.

Interesting results setter, cheers for posting them. 1350mhz c7 is a hell of a lot better than my ram so I guess that doesn't explain anything, wonder what else ibt is sensitive to. I like that you're passing testing, considered pushing for 4.2?

Yep, finally passing something, ibt seems to be a bit of a bugfest, ram currently running at 1547mhz 7-7-7-24 1T.

Think i will give 4.2 a run, but as ill need a bit of a jump in vcore temps will inevitably rise a fair bit, may have to do some rearranging of fans, put my 3 pwm fans (2 on cooler, 1 rear exhaust) as case intake/exhaust and use the 2 x 2000 rpm ones i have on the front at the minute on the TRUE. Those two fans were great at keeping my q6600 at 3.8ghz on 1.51vcore pretty cool.
