Was that directed at me? Its on water, but the room started out @ 19C ambient, 21C at the end of testing. My cooling goes, 355 pump + Xspc top-Feser 120.3 with Yate loon "m" with shrouds-heat killer 3.0 - Switech mcr320 with yate loon "m"Quote:

Turns out, it's a function of motherboard. I've tried eight different mobos, and only the two giga byte boards make a difference. That is,
I've validated 222x21 in SM with the giga UD5 but with full speed, I could do only
220x21. With the biostar x58, asus, DFI, and MSI boards, I can get 220-222x21 (depending on board) at full speed. In fact, I just set my personal record with the biostar x58 with full speed QPI.
Now all the haters who criticized PC and said he was intentionally spreading false info.... you can eat your words and you owe PC an apology
I had pressure modded the CM V8 and cut back on the AS 5, feeling that I had to much the previous time. Wasn't impressed with the new temps, so threw a stock TRUE on, temps dropped 5c (probably the paste), with the same fan. Curious at that point, I lapped the HS, and the cpu at work last night, pressure modded the TRUE, and dropped another 10c so far. I'm not sure if the temps will drop more as this is on fresh AS 5. Inlet air temp is 25c, the fan is a Scythe 110 cfm cheapie, just going to pick up another bracket to run 2 and see what I get. After work tonight, I'll open the patio door to drop another 10-15c, to see what water would offer me.Quote:

Was is "pressure modded"?Quote:

Vcore, -> could be psu, vrs, etc.Quote:

Is anybody here to give me an answer how to get Blck over 222MHz and how to get 215 MHz stable on my Gigabyte X58- Extreme?
my board wont go over 222 either, not even on phase or DICE. Sucks a fatty for sure.
ah crap those Xeons look really nice, guess i can't resist and will get myself also one. :D
But need to wait a few more weeks till they are more available and no price gouging is going on anymore. ;)
but on the other hand its only ~10 more months to gulftown....

I will find this way out tonight!
how does the D0 perform with 12 gbs of ram at high clocks ? I can't bump blck too much beyond default or it gets unstable..
They are nice but LOCKED!Quote:

- QPI link transfer rate locked
I am asking Intel through my supplier if they are really locked or this is due only by an immature BIOS.
Take care of it.
Thanks for your pic, up to 4305 I just adjusted vcor and vdimm, I never had to mess with my other voltages on the C0 series due to limited bus speeds. Anyway I turned off HT due to the air cooling for testing, and ran an hr of prime small fft's, with the only difference being vcor 1.312 and vdimm 1.66 under load (compared to yours :up: ), cores ranged from 66c-72c in a 19c ambient. Once I find the limits of the chip and mobo I'll back pedal the voltages if I can. Maybe we can get this batch # a little higher on the Giga !Quote:

Sounds like your bios :shrug:
There is not sorry :down:Quote:

EDIT: Tired of sharing and getting nothing back.
Thanks Roller11, I'll try in the next couple of days what it takes to get HT working at that speed, but this time I'll use the chill from mother nature. I'm no longer confident in my ram though, we'll see....Quote:
