thank-you very much for the detailed reply. i will get back to the Phenom and try some things you mentioned. for now though, i grabbed an X2 5000+ BE and have had no issues pushing past 281HTT...

You're welcome. I still believe it may push further, but can't tell what's limiting it. I didn't even do anything with voltages (auto) on the MSI and ASUS RD790 boards and managed +380 HT using an X2, it literally is simple with many X2 G2's as long as it's not a BIOS limitation especially with the 5000+ BE. Even ~1600 HT link didn't really cramp it at all.

Looking at the ss, somethings holding it back. I reckon nearly all 5000+ should be able to do +350 HT with ease if BIOS/MB is ok, just how 450FSB on a Intel G0 chip is a breeze. I've not tried clocking an X2 in it but will get a Sapphire soon and then be able to speak better.

Keep pushing it, much harder to squeeze +1MHz than on C2/Penryn.

Hmm the cpu just needed a bigger step in voltages as i expected.
Running at 2.55GHz now with 1.3V/1.25V 2.56GHz failed priming even with 1.35V/1.3V after ~3hrs. Starts to make me curious why it fails after 3hrs most of the time.

I sorted mine out. It was nothing but CPU limit and all that it requires is more cooling or more voltage.

Nice. 0743, that's why.

just received HIS 3870 to complete the spider platform and ive been unable to get over 11000 3dmark06 (highest 10949), whereas everyone else is hitting 13000+ but they are using other brand 790fx mobos... ive increased slot voltage limit to 150 and set gen2 high speed to autonomous with no difference in score... do i need to mess with "link aspm" settings? what else am i missing?

as for the 2/12 beta, i can run 234 ref with 1.2v SB once again

ive been unable to run 246 ref since the infamous 1/3/08 beta that everyone hated

What do you think about the 2/12 beta on the whole? Have you noticed any bug or problem so far?

have encountered no problems and NIC latency is back to normal unlike 1/3 and 1/30 bioses... settings in sig remain rock solid... however overclocking beyond 234 has gotten worse but im pretty sure it's because of the new memory im running and i havent bothered to get to know the sticks yet

Must say i'm not yet used to those small incremenst (0.00625V) for voltages that makes 0,025V increases look like huge steps. Makes me think it's something else keepen my oc back.

So after I replaced the crucials with gskill 6400 hk's and switched from 800 to 667 mode for the ram i managed to run 2.6GHz stable (216x12 12hrs stable, 217x12 testing).


I remeber OldGuy said samething about much better oc in 667 mode.
Will try to find lowes possible voltages here and gonna post detailed settings then.

Do you know any info about the CAAZB AA 0740MPMW ?
