Also gonna try for 4.5 but think my cooling might limit me as am hitting 74 on IBT.

EIST enabled
You ain't lucky mate :( I'm out to check the third DDR3 ram kit on an UD3 ...a bit better than the 2 others but still very limited
The Ballistix PC16000 did worse than the Value ones (Trichanel) wich gave me 880 C7 best ever atmo ;)

...now on the Ripjaws C7 PC12800 that need less voltage for sure but still hard work though !! Definitly not the NB to rock with DDR3
Are there not any DDR reference voltage adustments on the EP45T?
I'm sorry I don't know what you're referring to :p:Quote:

I know on my old opteron/dfinf4, I had to test the CPU at the multi and voltage it would be during c&q mode in order to guarantee stability if under mild load. Is the step down in voltage with C1E/EIST enabled at any risk of going too low whilst running at 6x multi with high fsb? What did you use to test it?Quote:

Those volts are insanely low for that speed! Well done!Quote:

thanks. the weird thing is it's 1.2625V VID, highest I've ever had on a wolfdale.
Nicely done, as usual, some great clocks & voltages on this board.
Jor3lbr, do your MIPS mosfet blocks help a lot with stability at >4.5GHz? I know mine run hot, and I want to push further but I think these are now the cause of instability after managing to get CPU temps more reasonable (and I'm still p95 stable at 4.5GHz).
Guys I never used the blocks... I ended up selling them all.Quote:

For stability above 4.5Ghz:
- Q9650 below 65oC;
- Right amount of memory tweaking (not too tight not to lose);
- NB below 70oC.
Fair enough, thanks for your summary.
With the cpu I have trouble getting below 70°C during p95 8k on the first core. the other 3 are sitting comfortably at 65°C at up to 1.4375v.
The 4th (weakest) core seems to increase in stability between 1.40-1.4125 and lasts around 10 tests during 8k at 1.4125, but it still fails, and gets worse when I go over that voltage. I know there's a fine line between temps/voltages here, but as the 4th core isn't too hot, this is the reason I'm starting to suspect the mosfets. But then it's a bit of a risk to splash out on some blocks if it's not going to help much more, and I'm simply reaching the cpu's limit.
It does have reference voltage. Its not something i considered! I have been leaving it on auto when going for a 1600 oc on ddr3 1333. Should it typically be raised above or below auto?Quote:

the DDR reference voltages should be half of the memory volts. I would start from there and work your way up or down :)
Perhaps skews are worth a try at those speeds too, they only had an effect when I was pushig my DDR2 beyond 1300, but in your case it might be more crucial :)
Does it step down voltage with EIST on? I thought it just lowered multi on the cpu when loads are low. Cpuz reports the voltage slightly higher (vdroop) when it is at x6 idleing as when at full load.Quote:

Ahhh... neither. Using my good old $30 Xigmatek HDT-S1283.Quote:

Great stuff Gurusan, Very nice indeed! I cant put vcore above 1.325 or IBT hits 76/77. My cooling is a noctua NH-U12P. All the reviews said it was great, turns out its not!! What cooler are using? Temps?Quote:

I see, good to know, thanks for the reply. I see you've got a 'voltage II' tab as well - nice :). The ram refs seem to have minimal effect on stability, although when I ran my reapers over 2.1v, the values did benefit from a notch above 0.5xvdimm, and that got me 1295MHz memtest #5 - 1 hour stable (plus a few passes of full test). As for the skews, on the MIIF, tuning the skews with one stick at a time in its own slot, and pushed to the limit was the best way to do it (and relaxed PL). Both sticks together makes it harder. Some settings will not boot at all, others will give you more stability, much like the CPU/NB skews.
The NH-U12P is great, some chips run hotter than others though, usually lower VID chips will run hot, I had a 1.165V VID chip once that ran hotter than the sun.Quote:

Also I don't usually use IBT because it heats the chip up so damned much, it's quite unrealistic IMO. I might do an IBT run later on to get in that 4.5GHz LinX stable club though :)
