Try enabling Load line calibration.

Trying that now, thank you :)

Edit: I can get it to 21X199 with Load Line enabled. 200 just seems to be a magic line, any more tips?

I am getting better temps with Load Line enabled BTW :)

21x200BCLK shouldn't be hard at all with a 3845B D0 chip. Try setting QPI/DRAM voltage (which is better known as VTT, I don't know why Asus uses that stupid term for it) to 1.30~1.35v.

I have core voltage at 1.320 and qpi/dram at 1.35. prime 95 still crashes instantly.

Give it some IOH voltage and try 1.2qpi/dram with 1.5v dram if you can.

IOH at something like 1.24?

And by dram do you mean dram bus voltage?

(By now you might be wondering what a noob like me does whit a mobo like this :rofl:)

I appreciate all the help guys :up:

Also, make sure your memory timings are being set right in the bios. Not just the 9-9-9-24 whatever ones, but all the rest of bank 1.

I copied everything you said to my bios, but one thing is not possible.The DRAM bus voltage cant go at 1.65 (which is the rating of my RAM kit) only 1.64 or 1.66 and with 1.66 I get a warning that I might damage my CPU. Which of the rating shall I choose?

And about the memory timing, I have no clue about what I should do :cow:

Edit: the voltages did the trick though, now running smooth on 4,217Mhz :D

Thanks a million for the help Roadhog and Shiranui Gen-An :bows:

1.64 and 1.66 doesn't matter. Whatever one you want.

See if you can run the memory at 1.5v.

I just got a blue screen again after 1 hour of Prime 95, set the DRAM bus voltage at 1.66 (was 1.64) now and raised the QPI a tiny bit. hope this will keep running. Would running the memory at 1.5v help keep stable?

No, but you're supposed to keep the memory within .5v of the qpi. You might need more CPU voltage.

So if I understand every thing correctly, the DRAM bus voltage needs to be within .5v of the QPI/DRAM core voltage? and I need to crank the CPU voltage from 1,35 to a bit higher?

thats just a myth lol
intels way of scarin us
i really doubt if intel even knows

bump your IOH PCIE to 1.55-1.6
you might wanna bump the qpi pll to 1.3-1.36 for higher ram clocks
pcie frequency 102

set cpu to 1.4 and blk to 210 for 4.4ghz dont be afraid as long as temps dont get too high
if you on air you can turn ht off for lower temps

that sounds good :D but I don't have a QPI PLL here in my BIOS and I just started in the OC world so I don't know which one you mean.

QPI/DRAM:cool:

and what rev is you ram

testing at 4,4 now, multi goes back to 20 when temps reach 70 though.

Yeah, mine does that also so I just settled for 4ghz.

use bios 804
and use the trick to stop the throtling on page 19-20
multi will saty @ 21x:yepp:

Do you risk melting the 24 pin connector if you have a revision 1 board?
