Now that I've found my max Bclk limit of 228-230Blck, it's time to revisit max i7 920 AIR overclocks with HT disabled

i7 920 3836A756 @4769Mhz at 1.59375v bios






Max screen capture capable @4680Mhz at 1.5875v bios



Max Super Pi 1M & Pifast
@4677Mhz at 1.5875v bios

40416 efficiency





Max Super Pi 32M

@4638Mhz - more efficient run (2178985)



@4652Mhz - less efficient run (2184839)

Lucky I took this screen capture first, as system rebooted before I could load the other cpuz instances :o

Probably at the limit of this cpu on air, close to swapping cpu out and testing the other i7 920 3836A756 I have

[Yil]

OMG

what are your the temps??

[Doctor Freak]

Really nice score,,,TRUE120 is still the excellent choice for air cooling

good job

[systemviper]

that is Sweet, love t hat rig...

[Achill3uS]

sick chip eva, the 32M is quite amazing on air

[mikesrex]

sweet, the most I have gotten on air with my TRUE is 215x21

[eva2000]

OMG

what are your the temps??

couldn't bare to look LOL... bios had 43-49C.. let's just say room temp was 21C when i started the bench session, and when the session ended room temp rose to 23-25C

Really nice score,,,TRUE120 is still the excellent choice for air cooling

good job

Thanks... got no other choice since only heatsink with 1366 mount I have on hand right now. Got Vendetta2 here but no 1366 mount.

that is Sweet, love t hat rig...

sick chip eva, the 32M is quite amazing on air

thanks, i suspected my previous 4610mhz with 21x multi was bclk limited so once that was sorted could squeeze a bit more. Now I'm both mem clock limited on 10x multi (need some A-data 2133x hehe - hope A-Data is reading this ) and cooling limited I suppose

sweet, the most I have gotten on air with my TRUE is 215x21

congrats to ya too

[The-Fox]

WOW eva, you never stop do you :P
That is some impressive chip you got there, remind me of its full batch# ?

You go to go subzero with this and the real limit !

[Jor3lBR]

Nice clocks EvaDFImaster! :cheers:

[thienloi]

amazing congrats!

[Solarfall]

that i7 920 is starting to look nice eva.. lol i can bench my 920 on 4769mhz clocks in 3dmark 06 with my cascade.. these chips scale really terribly with cold.

[CryptiK]

The Eva series was born to run SPI32M on DFI (lol) Very nice work mate that's one hell of a chip/board combo. Crazy it raised room temp so much during the benching.

[jugeen]

crazy results George! that chip is HOT!

[DavidNJ]

Questions:

1) Did you lap your TRUE and processor?

2) Have you tried some 3000rpm fans, since these are kamikaze runs anyway?

Great work...

[ReverendMaynard]

absolutely insane eva.

[eva2000]

batch is plastered across every screenshot

Nice clocks EvaDFImaster! :cheers:

thanks mate

amazing congrats!

thanks

thanks... dont say that i'm hoping my 920 continues to scale with colder temps LOL

hehe thanks... i'm surprised how well the 1GB Gskill PC3-12800HZ HCF0 module held up against the Corsair 2133 stuff!

crazy results George! that chip is HOT!

thanks all i need is some of those new elpida ics for 1150+ 7-8-7-x action

Questions:

1) Did you lap your TRUE and processor?

2) Have you tried some 3000rpm fans, since these are kamikaze runs anyway?

Great work...

thanks not lapped... haven't tried the 3000rpm versions, but i do have some delta 190cfm ones lying around from my crazy high speed cfm fan obsession days haha

absolutely insane eva.

thanks

[NameTaken45]

awesome temps and crazy OC, great job.

[Zucker2k]

Impressive, as always. DFI showing a lot of clout with their x58 offerings, but nothing like the hands of a master clocker to coax the extra juice out of the hardware.

[knissel]

amazing oc on air! I can't wait till my true comes in!

[SAE]

George, you just have to be a cyborg or something like that. I cannot imagine when you got time to sleep, eat or to do other essential things pulling new incredible results everytime I have a look at "Xtreme overclocking" forums here.

You be a dayum machine, huh!?

[eva2000]

awesome temps and crazy OC, great job.

thanks... now to aim for sub 7min 40s hehe

yup DFI X58 really holding it's own especially in aiding mem clocks

amazing oc on air! I can't wait till my true comes in!

remember more fanage the better

darn my secret is out.. guess which is me

[SAE]

Humm... you must be Mr. Red as he's the prettiest!
Did I win a lollypop?

[STi489]

WOW! Was this chip tested on any other boards? SWEETAZZ!

haha avatar gave it away i guess

WOW! Was this chip tested on any other boards? SWEETAZZ!

[PcCI2iminal]

damn nice George
