Sandy Bridge FPO Batch list (Excell sheet)

[Leeghoofd]

What would the prime settings be exactly? I have never used the custom setting before.

I always set this setting and then let it run for a few hours. Example below for 2500K, for 2600K it automatically sets 8 threads



As mentioned before there's no 100% bulletproof stress test. You can prime for hours/days, then run a simple game and the rig can hang. Same with the LinX vs Prime discussion. One of the two can be stable while the other one caps out.
I leave the option open to use either one of these two. Some will say 12 hours or even more is required ( for prime95 test ) Others say 25 runs is not enough either for the LinX test. I just find an hour of custom prime 95 and more than 20 loops of LinX more than enough to get an idea if it's stable or not. If you want to do more loops or continue stressing longer, be my guest.

Not a Sandy Bridge user atm--but I have an interesting observation for Sandy Bridge when it comes to LinX (since there's so many LinX results in this thread). It seems that it has a negligible, if negative performance difference per clock from Core 2 Duo.

Looking at leeghoofd's example of ~56GFLOPS at ~3GB problem size and 4.5GHz, that's a 25.8% advantage over a Core 2 Quad Q6600 with 44.5GFLOPs at ~3GB problem size and 3.4GHz.

A 25.8% advantage is significant but 4.5GHz is a 34% higher than 3.4GHz.

It could be an HT On/Off Issue

Comparing technologies based on a single benchmark is never a good idea. Look at the below results of my upcoming review for Sandy Bridge :

All CPUs at 4ghz with rams at 1600mhz CL8





Clock for clock mate (FSB of the s775 system was 400) yes you can squeeze more performance out the old setup with a higher FSB. But even then Intels latest creation is so much smoother, more responsive. I even swapped my i970 for a 2600K

Haha I see - touche Don't get me wrong, I wasn't challenging you, I just thought there was something I didn't know about task monitor / realtemp load monitoring on SB CPUs.

It was a good tip Cedric, hence why I added it to the ahum rules... just messing with ya

Enuf discussion : RESULTS PLZ !!!
