Good eye re EVBot ports on two of the four cards !...wonder whether those are the special KPEs w/ Hynix he referred to over at his site...anyways the whole assembly looks like it's kept in a freezer / meat locker 'until needed' tongue.gif

GPU max temp is about 25c sometimes it goes around 32c CPU always hot at the clocks I set.

Gonna measure it and post back . on FS thread I'm below Alatar. " I had not posted any screenshot here or there.

...I can tell you that even w/ 2400 watts, it's tough to run 4c 780 Ti Classies anywhere near their individual top speed at below 1.36v nominal, even w/ PSUs drawing from unrelated phases ...might have to convert some 110v phases to 220v... ...if you ever watch KingPin, 8 Pack and so forth bench four cards on LN2, count the number of PSUs they're using...I have seen up to 5 lmaosmiley.gif

These look this way just for pics lol. If they were insulated and everything def wouldn't look as cool. Youll see pics like this from various places and they just pour ln2 without any power just to freeze the cards for cool pictures.

Indeed, have seen it. Just for peace of mind I will run each of my hardware individually and add up the number with the killwatt and rerun the same settings with both hardware CPU/GPU just to make sure. I had run a dedicated 15 amp breaker only for that.

PS: To all KPE owners,

I have released a KPE bios with boost disable to correct the +13 bin and some issue for a small oc I have seen it here. Have anyone tested it? Any input.

I just tested it, works great. It automatically lowers to the nearest lowest +13 bin core but sometimes it goes 1 bin further. For example, I had set core to 1393 (+400) and it went to 1372 instead.

Has anyone tried OCCT for GPU testing? I'm getting a lot of errors even on "stock" clocks for the card, so I'm confused as to whether the program is faulty or if I have a bad card.

You should try using games to see if your overclock is stable. Bf4, tomb raider or far cry 3 for gpu and crysis 2/3 or batman Arkham origins for memory overclock. Benchmarks like 3dmark11 heaven 4.0 firestrike will give u a general idea where to start. Then try games and lower clocks or raise volts from there:p

My stable core overclock was at 1282mHz at Heaven, Valley, Precision X scanners, and 3d Mark 11 with 0 artifacts at extended periods of time. However, hundreds of errors pop up when I try OCCT. I'm going to flash my bios back to stock ln2 and see if the errors still occur.

Edit: It seems the Skynet Rev. 5 Bios was causing the errors, so is there an alternative Bios that has been working well for you all?

hmm thats strange, anyone else got the same problem ?

should the stock LN2 be used for 24/7 (lets say gaming) and skyn3ts rev.5 bios just for benching ? any ideas ?

I am asking becouse I will be joining the club soon smile.gif

PS: which version of classy tool works with skyn3ts rev.5 BIOS - the "Classified_v2.0.4.2.zip 204k .zip" from Classified owners thread or some else ?

Thanks

Use the latest one

Also, I haven't had any issues with skyn3t's bios.
