Looking for some help, got my E760 today installed a EK full board block temps are great and have my W3520 @ 4.4ghz linx stable. I cannot get this board above 220blck same with my old board is there something I'm missing?!?!?

Sounds like your CPU won't go any further. BCLK, unlike FSB, is not just a function of the motherboard. Think of OCing AMD chips, where the HT link multiplier had to be adjusted as you raised HTT. On i7 chips, however, you're kind of stuck.
I'd try loosening out the Classy MCH strap and lowering DRAM clock to see if you can get some more headroom. If you can push BCLK up further, your chip's IMC is not happy above 220BCLK, and there's not really much you can do on the motherboard end.
I do agree with Souls (above), It could simply be the end of the line for this specific cpu. However, we can help you more if you provide us with a template of your BIOS settings.
I did get stuck at about the BCLK 218-220 level until I made the following adjustments;
PCIE Freq = 105
QPI Signal Comp = Less
I was then able to advance the BCLK up to 236. I got to my target clocks & multipliers at that level. I do not know if I have BCLK headroom remaining.
linuxfan informed me of the pcie scaling issue so Ive gotten up to 225 so far. So I think I figured it out.
If you get it figured out, throw up a BIOS template for the rest of us who are still tweaking ours ;)

Post your results, please, I am curious if this has something to do with the motherboard.
Some people have >20us results, mine is 70-150...
Started to get random reboots last night. This morning my system didnt post at all. It stops at code FF.
Running: at 4.2 ghz watercooled for 10 days.
NB was a little high 80-95C at full load.
EVGA VDroop Control - Without VDroop
CPU VCore - 1.28V
CPU VTT - +300mV
CPU PLL - Auto
DIMM Voltage - 1.65V
DIMM DQ Vref - +0mV
QPI PLL VCore - 1.400V
IOH VCore - 1.400V
IOH/ICH I/O Voltage 1.650V
ICH VCore - 1.250V
PWM Frequency - 1067 KHz
So i tried resetting cmos, batteri.
Tried with diffrent mem, gpu, and psu still code FF... Any suggestions what to do? RMA?
When my E760 was showing FF code it was dead, but it was because of the crap PSU which also killed 2 DFI T3eH8 before :mad:. Some people are saying pushing the BIOS chip at its socket helped but I dont know u can try. I even opened the socket removed the BIOS chip and put it again and nothing for me, but as I said it was the PSU for me u can try I hope it helps :).
You can try also removing all components from the board and try with only 24 pin ATX connector and one +12v for the CPU if its still showing FF and nothing else, and the bios chip thing is not helping I think u should RMA, and the NB temp is high u should think for a better cooling I`m wondering how high is ur Vreg temp.
The BIOS chip is located here.
thank you
il give it a try after work.
Hope it helps mate. Its sad when classified dies.
Code FF is not MB death in & of itself. I am currently running fine with FF. I disabled "P80 Show CPU Temp" within the Onboard Devices Bios Menu. Code FF presumably is the last of the POST sequence codes before the LED starts to display Temps. In my early Classified ownership days, I spent lots of time trying to track down "reserved" LCD Bios codes that in fact were Temps. lol...
Try to reset your bios boot device to a bootable dvd or cd & attempt to boot from that device instead of your HD. This will eliminate another set of variables.
Best of luck.
Yet another suggestion. In the past, I have damaged my stored profiles in the classified's BIOS. Try clearing CMOS, restoring default settings, & then manually rebuild a simple profile for your config. Keep it simple, no OC etc.
In the past, I have had ide/achi & uncore settings float in an uncontrolled manner with this board. I needed to manually rebuild all my profiles to cure this. I bring this to your attention because the symptom I observed was failure to boot a known "good" bios profile.
FF = full function. ;) (normal)
Ok guess my board is dead, and I really dont know what killed it?!
This mobo was stable at 4.2ghz for hours of priming. Now I cant get past the f.... FF same what. Maybe its the CPU? Anyone heard of someone fried there 920?
Guys,
My system recently became unstable after changing the pci payload size from 128 to 512. Not sure if it was because of that but what I do know is dropping my memory to under 1600mhz restores stability. Was mildly Oc'd at 3.2ghz (1.275v vcore w/ 1.35v vtt) on a 920 D0. I do have OCZ 1600mhz back xmp ram 3x2gb and have heard that OCZ and Evga don't play nice. Also setting cpu vtt to auto raises vtt to 1.40v. Is that even safe?
Thanks.
not sure about the payload myself but 1.40v on the vtt is perfectly fine
I have the same issue with my 950, at 4.2 is kind of OK, pushing to 4.3 and the 950 asks for relativily high voltage, I had no luck running it at 4.4 even with voltage at 1.48!
My old 920 was able to reach the 4.4 with 1.46 voltage easily.
