System Specs:
I7 920 D0 (49B)
DOMINATOR GT 1866
eVGA Classified x58, bios ver 61D
Noctua 1366 SE <---- IMHO the best air cooler :)
and lotsa TLC.
:yepp:
----------
any input?
I plan to go 4.8 when winter comes and room temp. will be around -15C
Tips?

pull 2 sticks out and turn off ht and would have gone higher :)
any bios settings? how much pci-e mhz ?

+2 on that Bobby.
Dropping HT and going single channel will open up a bit of thermal headroom instantly.

Nice job! HT is off, everything else is on, correct? What voltage did you need for that? B batch or A batch?

Wow nice! What vcore are you using?
Did that on stock cooler myself :D Nice score, keep pushing :)

Wow Rouvio.
Can you mention what thermal compound or grease you use for that? Noctua's or something else 3rd party?

Nice clocks but that looks like a pretty old version of CPU-Z.....
What are your temps on that crazy clock speed?

Sure!
I have always used Arctic Silver 5. *always*.
Once you use it.. you can never go to anything else :)

That's the eLeet (EVGA's version of CPU-Z) version 1.06.3 (http://www.evga.com/eleet/)
Temps (idle of course..) for this clock are 45-50C.
Out of curiosity I did try to run SPi1M but never made it past the 5th/6th loop..

any stable on bench ?
rouvio

Well,
under similar conditions (but lower clocks & Voltage) I run SPi1M:
I know and have a "gut feeling" the system can do better. maybe even go close to 8.0s

The 4.75GHz is for records (personal), with no intentions of benchmarking.
In the following days I'll try to go higher and will update here.
*edit

nope sir! HT is ON :)

Oh, I see. Still, to even boot at those clocks on air is amazing! Great chip you got there for sure. :up:
