Is this pretty decent for a 780 Classy?

Looks like a stock clock run. Is your 780 overclocked at all?

Heh, yeah it is. That was with 1241Mhz and +600 on the memory offset. I believe stock nets me a score in the mid 1,400s.

Ah... okay. Did you do any of the tweaks that are listed in the OP of the Valley thread? That maybe why your score seems low to me.

Currently pushing about 1.375v through my 780Ti classified and constantly get black screens and then reboots.

I thought it was a power supply issue, so swapped out the 860w for a 1200w and the issue still occurs.

Anyone know what is causing these black screens at high voltages?

Here's after doing some of the Nvidia tweaks Still on 1241Mhz/+600 mem offset




Also anyone have any idea why one 780 Classy at +115 runs at 1241Mhz and another 780 Classy at +122 runs at 1201Mhz in games/benches?

Thanks!

That seems low. I think I get around 75fps at that clock. If you are on the stock bios the different clocks you are seeing are normal. Are cards boost to a different clock. It's not usually what it says on the box.

Also with my first 780, going from +125 to +115 only results in a change from 1254 to 1241. Is this normal, or am I missing something?

That's Kepler Boost. With standard (and most other) bios's, you have a base clock, a boost clock, and then each card has a specific random (it's not really random, just seems like it) Kepler boost that it adds to the boost clock when it is not throttling. Also, it is based on an internal chart of 13 to 13.5 MHz increments.

Hmm. My other 780 at stock started out in the mid-1,400s as well and couldn't hit 1,200Mhz, and as a result wouldn't even touch a 1,600 score in Heaven. Maybe there is something else going on then.

Ah okay, thanks! Just found it odd why the core Mhz : offset modifer wouldn't be the same across 780 classifieds.
