Whats your opinion about this?

Max is typically TJMAX - 20c IIRC. Which would make it 80c for sandy-e. Your idea is sound, but don't forget to set an OC profile first so that you can just reboot and load your old profile easily when the weather cools.

I've considered going for a per core setup, but it didn't work out within 15min of testing so I gave up on the idea.

How often do you run it that hard?

How hot are your idle temps..

Hmm, I've got 5.1ghz prime stable now, temps are excellent at 73c but voltage is getting up there at 1.512v. I shudder to think what 5.2ghz is going to require.

I'd really like to see what someone could do with a 3820 and some LN2.

I have been folding for the past 3 days at 4.625. CPU is 50-52* with a h100. GPU is 65*

5.66ghz on LN2. Imo the lack of multipliers caps the fun.

5756mhz is the current record, on a single stage. 5681 is the current best with ln2.

This poor chip needs more multis!


Man, looking at the rest of that list... The volts on some of those 5125 and up scores, yikes. Forgive my noobness, but what's required to post besides the cpuz validation?


I just finished a Heaven run following the Heaven 3.0 thread at 5.1. ROFL, I incidentally left my rig plugged into the killawatt during the run. I was beside my self in laughter when I saw it roll past 1645w. By the time I snapped a pic with the cellphone I could only get 1600w. I hope my wiring holds up, luckily that circuit is dedicated to that rig.
