About to go back to stock, figured Id try a 27x133, which I had before my RASA kit. And its been folding almost 24hrs. now, with memory at 1600, and with every setting on AUTO. So I think its safe to say the memory is ok, and this is with a 1.5x unc. Going to try 29x133 and see how it works, should I still leave everything on AUTO when i go 29x133?

I noticed a QPI speed setting in bios under, slow mode was one of the options along with some other rates. Should that be changed when change the QPI voltage?

Also, I'm using CPUID Hardware Monitor to check my voltages, and noticed PLL shows up as .10v and not 1.8v or whatever I have it set at. Whats up with that?
If your running default BCLK your QPI multi should be at x48 (133x48=6.4GT/s) When increasing your BCLK you don't want your QPI link going too high, try to keep it below 7.5GT/s your multipliers should be slow mode, 36, 44 and 48. I'm running 200BCLK with a 36QPI link multi giving 7.2GT/s. You don't want it on slow mode though!

The fact that it seems to run fine on standard BCLK looks like it could be your QPI link maybe being too high if you are using the 48 multi.

Some more findings, I was able to reduce my VTT from 1.4 to 1.325V by increasing my QPI PLL Vcore to 1.175V from 1.15. It helped the load temperature by a couple of degrees.
This is to achieve a 3820MHz uncore.

this thing wants to be stable so bad it can taste it. Worked my voltages upped slowly at 25x160. vcore to 1.35 no more 101 errors. x124's up to 1.35QPI, Folded for 3 hrs so I was thinking this could be it, woke up, still folding. Left for a few hrs. came back and it was a x124, so about 15hrs of folding and it x124'd. I dont think I should have to push the QPI any higher than 1.35. I swear if someone wants this chip for $650 they can have it and try their luck.

If it takes that long to fail, I'd start looking elsewhere for a fault. Either Motherboard voltage regulation or power supply... Even maybe ambiant heat and electromagnetic field...

Not sure why you're upping any bclock at all- especially if you're getting frustrated with QPI bumps. Drop your bclock to stock and up the multiplier... You bought an extreme edition- enjoy it!

Try a 133x31 combination with your current voltages... I'm willing to wager you'll have some success there. Brings everything but CPU back to stock... Besides, depending on what you did with your RAM (did you bring it up with the 160 or drop it down?). 124 could just be telling you it's too high, if in fact you underclocked your RAM to accommodate the raise in bclock.

Don't know why I'm trying to help, 650 is a steal.

I've tried the 133x131, and itll last for a few hrs before x124. left everything the same after the folding x124, and running prime now and trying to keep an eye on voltages, about 3hrs on prime blend and nothing bad yet. Yea RAM has been underclcocked the whole time, unless I did a multi increase with 133bclk.

What voltages affect raising the blck and which affect raising the multi?

2nd power suplly I've tried. CPU staying under 60 the whole time. Everything else is good as well. electromagnetic field...I dont see anyting to cause one that problem.

Anything I can check to see if its the mobo?

Hmmm, well then there's a chance it's telling you your QPI is too high. I leave my QPI at 1.35 as well and don't have trouble with it at stock RAM speeds at that setting. Where I was having trouble was the 133x33... It'd last for days of folding 2684s and then crash on 6900s all the time. then I was getting a3 core errors. That was a pain in the butt- because they'd happen at 80% and then dismiss the current project and get a new one. Argh.

Believe me, I feel your pain.

If I were in your position I'd go back to basics... stick to multiplier Oc'ing and leave everything at stock. The only reason you underclock is when you're forced to overclock through bclock- "take it out of the equation." In re-reading your post, I think I see you brought it back to stock when you do the multiplier only.

I'm confident the computer knows what the problem is even if we don't. You might need to start from back down at 1.30- and start working it back up again. At stock (bclock that is) and using just the multiplier to creep back towards stability. I know with folding you're going to need some significant voltage on your CPU though- Above 1.35 that's for sure.

And hey, let's face it... if you're at stock RAM speed and you're giving your RAM the voltage it needs, you might just have a chip that needs more than 1.35 (assuming it's in fact too low).

Are you working with any differential amplitude?

I'll let prime blend go for a bit more then go back and try upping the multi. If I dont figure anything out I guess I'll just go back to stock for the foldathon tomorrow.

Oh and no, havent messed with any amplitudes.

You want me to put the vcore back down to 1.3 along with the QPI??

Give me a bit to respond to this... I'd leave your vcore where it is!
I have to do shift change!
