Yep just balance out the voltages right and you can bench 1m pretty close to max valid on this board. I did not screw around with master PLL skew though.

Looks like you have some competition raju. Both of you have beyond impressive results.
256 blck - 5383.78 MHz

He was on MSN with me while we were both getting over 254. You should see his backup :)
I have a feeling that I will end up with a Classified in the end.
yup, i got a 1M out at 248BCLK with my max validation at 251BCLK. i spent a total of maybe 90 minutes trying and did a bunch of 32M in that time so yeah, still lots of room to go. not sure if i can catch you too though, you really kicked it up last night :up:Quote:

Yours has room Jody 4 sure, jus a bit more time. Tha's the beauty of cascade at times you can spend more time tuning. I am going LN2 tomorrow to see what happens.Quote:

yeah, i think i am just going to slap the single stage on it and do some work tuning. i spent literally 10 minutes to get 250, but those last 5-10 BCLK are the hardest. i benched 32M at -55C ~ -60C only last night, going colder didn't help. i could bench down to -90C and had no problem booting the whole setup at -125C, at -130C i wouldn't get POST. again, not much help below -55C though...for 32M anyway.Quote:

awesome, any issues with the gpu with raised pci-e mhz?
Not yet;Quote:

hey raj, any insight on setting cpu skew? Seems I can get a bit higher at 100, and above 200 = no boot. Not alot of reading online explaining what it does. What do you have it set at?
The skew offered on this board offsets the master PLL output to the CPU against that of the signal that is provided to the IOH. The IMC write levelling process works fairly well 99% of the time. Any and all bencmarks I have presented thus far have left this at stock. Others may use different valus, but I have not seen a single instance in which it has helped me personally (yet). The IMC seems to override whatever you set anyway by offsetting any corresponding signal lines accordingly so you almost always end up back at square one.

Hello,
could you post the Voltage settings for those beautiful BCLK´s ? i have changed now 5 D0 CPU´s and i cannot run over 220 BCLK. i don´t know what i can do. is your Mainboard selected?
Hi,
It's not 'selected' especially. FWIW, the ES board actually booted better than this retail - and both I've managed to get to the same clocks. What exactly are you trying to do over '220'. I'm not running prime, if that's what it is you're doing then 220 is the limit. Also, each CPU is different, not only this but voltages required vary with temp.

Raja
yes i am trying to Prime. so 220 is limit? other boards like DFI UT runs prim at 227 or more. do you think with waiting for new bios version there will be more?Quote:

not all boards/CPUs are going to be the same. because a single DFI UT runs prime at 227, doesn't mean anyone else is going to. if you are on air/water and looking for Prime stability...220 is already pushing things. anything higher and you are not only fortunate, but extremely fortunate.Quote:

Even if you could, there are other multipliers to use, and BCLK perf in 24/7 systems across multi's is close to benign in all the benches and game tests I've run.
yeah, i was just going to say...why such a high BCLK anyway. i mean, are these 920's really running over 4620MHz on air/water for prime stability??? and no i haven't seen anything north of 220~222 for prime stable BCLK...although i am not looking.Quote:

I'll test my good 920 between the two boards shortly for any variance around this point with all else being equal. Although I'm already fairly convinced that my CPU is not one that can do it simply because it's not the best clocker at ambient temps. the fact it runs down as cold as it does is a pretty good indication of this.

do your cpu need on the DFI more VCore or less ?
No idea because I have not even started to test the DFI board yet.
