I can't get away long enough to go to the LN2 store to pick up LN2 and try myself.
Hell yeah I've seen a few but normally in annoying spots like -170 that are quite hard to control, right in the middle of supernova

just tested a 3770k on mvg and ended up with 6,4 cpuz.
@ the 6,9ghz cpuz guys, how high can you bench 3d? (vantage/ 06/ 3dM11)

It wasn't really coldbug, but rather cold "issue" with IMC.

All you guys know it's similar behavior like the 990X Gulftown: some chips liked cold, some didn't. Some chips liked high VTT, some didn't. Some chips did 5G uncore, others didn't, etc etc etc.

Same board had no issues with another chip we tested.

@sof:
of course am3, 01, 03, 05 are interesting. but as i dont have sbe (anymore ) i want to know 3dM11/vantage stable settings.

first i was in a "sandy-mood".... like if 6,3ghz would be stable for 1m, 6,2 should work for 3dM11...

but ivy doesnt seem to behave like sandy in terms of stablity, so you cant expect every benchmark within a 100mhz range are stable.

i guess (not sure yet and waiting for confirmation of the other guys here) that there is a huge gap between cpuz-stability & eg. vantage/11. - if you guys cant share because of nda, please just drop me a message


basco and i tested a retail 3770k on mvg 0701bios yesterday:
max cpuz: 64xx mhz
multiplier 62x & 63x possible to raise in win (asus software - no rog) but 63x not stable.
max 3dM11: 61xx mhz

interesting:
have to boot a minimum of 102,8bclk to prevent from cbb.
after boot i cant lower the bclk to 100 -> freeze at 101bclk.

it would be cool if you would share some insights of your oc-experience here, like
-scaling with volts/temps,
-how many chips binned (&mentioning the worst results so the average joe knows already what to get ),
-3d stable settings (everybody is posting spi)
-etc, etc

thanks
