Forget using 1T and try 2T instead. The only places you can "see" an increase in performance with 1T is in memory benchmarks; not even 3DMark shows an improvment between it and 2T.
On the other hand there's a very good chance your system will be more stable when running with 2T, and theres a far better chance you'll get a higher stable HTT rate.
Thing I've found out over months is that once you muck with it like we're doing it seems that even what was once stable will be unstable.
What I've learned is to go back to square one ...a good safe stable setting a just fold for awhile ...like a day or two. Then gradually creep up the ht a mhz or two.
You were at 266 before ...maybe try 264 for a few days and lets see how stable we can get it.
edit:\I'm having a tough time going right back to my 242 ...I had to back down to 240.
Okay, I've gone to 275x10 and it is pretty damned stable. I played far cry at max settings for about two hours. Been photoshopping, etc. Temps are good at 41c under load.
Backed down to 277x10 and got 6564 again, but with a CPU score of 6233 this time. How is the total score the same even though the CPU score is higher?
graphics score is starting to suffer.
At this point I would recommend trying the following until we get a highest stable cpu.
set peg mode to disabled
set peg length to longest
set ht pll control to normal.
At this point we don't want video instabilities getting in the way and your video score will probably rise a little from what it is currently. I'm confident your ram isn't in the way either but you can work on those later. Since your ram frequency is still below 260 I think you're ok with 1t.
See my post in your A8R-MVP thread... Totally stable except for prime95. I'm willing to continue using my system at 275x10 because I can do everything that I normally do, but I'm really curious as to why Prime95 crashes. I guess I cannot consider this 100% stable.
I was under the impression that when you torture 2 cores you should run 1 instace per core with both unchecked. That way you're testing cpu0 and cpu1 independently. Run 1 instance with no affinity checked to test mem. That's how I've been doing it.
that's strange. I did a reformat with only minimal drivers this weekend (by the damndest) and I am at 260x10 @ 183 mhz 1.35v + ov and it seems quite stable ...800mhz ht to boot. I haven't seen this before.
Had you installed the amd hotfix? I haven't done mine on the reformat yet.
Brian ...next time perhaps try 2T when you take it past 260. It's documented everywhere that once you get to that high it's still fast and no real different between 1T and 2T.
I noticed when I had the board set for 1.4v + ov it only registered as 1.40v in cpuz. Perhaps a problem with cpuz program.
Now I have it set at 1.35v + ov and cpuz shows 1.45v fluctuating.
I'm thinking that since the chipset is so new some of these programs will have issues with measurements at times.

I am going back to 270x10 for now. It seems much more stable at a lower HTT. I'm still at 1T though. Sorry chris!

drop the FSB (HTT) or up the vCore a tad
prime won't fail, he'll just tweak his BIOS and try again.
Oh, you meant the other "Prime".
I was having some hard lockup issues, so I took everything back to stock. My computer hard froze after a day and a half
sigh.

It had been running stock @ 2T for over a day, doing nothing but folding, and it hard froze last night.
But first ...are you using any usb devices? Try disabling v2.0
