I was also wearing shorts and a T-shirt...yeah, it was cold, and the air coming out of my case's exhaust was like ice.
Anyways, here are my exteme air cooling results:
I think it's awesome.
wow crazy temps, lol
I GOT 3.3GHz 1 HOUR OCCT STABLE! Who says 780G can't clock! Now i think i can probably get higher
EDIT: And some tips overclocking the 7750 (on 780G?), DO NOT CHANGE NB FREQUENCY, I did 2 tests to get this 1 hour OCCT, my first one, NB Frequency @ 8x, HT LINK @ 6x, crashed in about 12 minute OCCT, however next time, I increased NB Frequency to 9x, so its running @ like 2.2GHz? and was able to get a 1 hour OCCT stable
3.31? lol wanted 3.3 but 245 x 13.5 is closest to 3.0 (or 244 x 13.5 = 3.294 lol)
HTLINK = 1200 so 6 x 245
NB FREQUENCY = x9 so 9 x 245 = ????
CPU FREQUENCY = 13.5 x 245 = 3307
CPU VOLT = 1.475
NB VID = +0.075 = 1.4V
NB CORE = +0.2V = 1.3V
edit2: and validation http://valid.canardpc.com/show_oc.php?id=575620
Temperatures topped @ 32*C, however NB reached a unpleasant 56* in the hour.
Will do some more stability testing next week after i finish this month's quota off, lol
edit: failed, it might be the ram failing me, crappp, i was unable to do normal tasks on my overclock
but @ my 3.2GHz i ran a 3DMARK06 benchmark got 11978
