A-Grey - why are you using so low voltage on ram? From what I've read everywhere they are rated @ 2.1v. If you are trying to achieve 1200+ with lower than rated volts I'm not confused why you can't get them stable. If I were you I would try to volt up to 2.4 - 2.5.
I tried with higher voltage. It's worse. It fails immediately or ends up with a crash.Quote:

I tried with DDR 1117MHz too and I have the same problem.
I can change the amount of stable passes in LinX with changing the NB Voltage but I can't make it complete stable.
This makes me believe that it's a problem with the BIOS and my hardware.
What the hell is going on at ASUS. :confused:
They released a BETA BIOS for the Rampage II Extreme to have better OverClock support for XEON CPU's that officially aren't supported. :clap:
http://www.xtremesystems.org/forums/...d.php?t=224144
All that we get is that stupid answer to " Trial and ERROR :mad: " by yourself and don't see any changes in the ASUS Rampage Formula BIOS for OverClocking our official supported hardware.:shakes:
Perhaps we should all buy a XEON CPU. Maybe than we will get some changes in the BIOS for OverClocking our unsupported XEON CPU. :yepp:
[QUOTE=greg.m;3797693]Here i am now having again the same "old" instabilities. Yesterday i was stable with settings you see above, doing 700% memtest errorfree and 3 cycles primesmall and today with exactly the same settings im getting BSODs and lock ups. Now im back again trying to find which setting causes the prob:shrug::confused:. A-Grey it seems that we didnt have so much luck with our hardware choices :mad:Quote:

I think that we've got compatibility issues with this memory and the board.
Since when is 8 X 465MHz = 3.74GHz. That's what it says in the post screen. Not always most of the times it says 3.73GHz and that's a little bit closer to 3.72GHz.:D

for one more time i see that nbv is the most importand setting, at for me
The thing how safe is 1.69nbv? As you can see i dont have temp problems but is it enough for not damaging the nb?
No, these are built on 90nm process node. You're fine.
Nice!!!:)Quote:

Not really, it may cause some really odd behaviours. For so high rated sticks I wouldn't go lower than rated voltage. Anyway does lowering voltage by 0.1v gives you any visible drop in temps on ram?Quote:

With Prime95 on Blend everything was fine for more than 2 hours, i checked the memory with memtest and everything looks just fine, when im doing Small FFS a core is failing after 15-20 min, Intel Burn Test and Linx is failing after 3-4 loops, do you think i need to give a little more voltage to my cpu?
Probably, whatīs about the rest of volt and GTL settings?
Please show us, itīs easier to help then.
Thanks for the post. very good info..Quote:

I was running 105 on the PCI change it to 110. i could not see any difference
but then again i did not try the +1,+1 stepping so its my bad.

I used this settings for more than 1 year with problems till yesterday.
I'm surprised that it runs so well with the PCIE frequency at 110MHz. I tried to change the frequency with one of the previous BIOSes to 101 or 102MHz but my stability was gone.Quote:

I didn't change my SB and SB 1.5V voltage. I left it on auto and the voltage didn't change so I think that it isn't necessary to change the voltage.
So i did this PCI starting at 100, 106, 108, 109, 100 and 112
I would think from the results that 110 is better,
PCI at 100

You guys that are upping the pci-e freq are using single vga cards??? Try it with a pair of cards, bet it doesnt happen....
i dont know.. if it will work either.Quote:

I could do 25 pass linx, run 200% memtest double instances and run 3 cycles prime95small. I changed CPU GTL Voltage Reference from 0.63x to 0.62x and set cpu skew @ 100. I dont know if its my idea but now all core temps are the same under load. Before these changes the core 0 was 2-4 degrees higher than core 2 and 3 and core 1 was always 1-3 degrees lower core 2 and 3 - under load.
Nice clocks. :up:Quote:
