So just received my EVGA 780 Classi today, would i be best unisitalling my current Nvidia drivers before installing the card?

straxusii · 30 Oct 2013 at 14:42

Went from a 680 to a 780 phantom (standard), can you guys give us an idea of where to start on the clocks?

Using PX I guess we unlink temp and power, put power to max and temp to whatever you want, I'm temped to max at say 84 degrees.

Seems like you get the most from upping the core, does the mem have much impact and what's a realistic start for both?

What card you upgrading from?

Can't imagine it would matter which drivers are in there currently as long as put the right ones in after.

Hi,
I just got the MSI 780 TF-OC but when i try to enable windows8 functions in the motherboard bios i get some GOP bios warning telling me this card isn't windows 8 certified; anyone know how to fix this?

No it does not matter was just checking prior to installing. Its one massive card have to move some of my WC stuff about for a good fit. But its stupid fast and not even touch the OCing yet

On my msi ge I have +150 on clock and +100 on memory. That is moderate overclock you could start with.
Anyway, please let us now how your phantom is clocking, I am tempted to buy one.

Its nice to see Shadowplay is here at last, albeit only in beta right now. I was testing with it in BF3 last night on my 780 and it worked really well. Virtually no frame rate drop and really nice quality MP4 @ 1080p, decent compression as well.

How does a benchmark-stable overclock translate to game-stable? I assume I'll have to knock a bit off, but I can't access the internet on my rig atm so can't test it for myself. Is there any way of estimating?

Currently looping Heaven Valley at 1189/3499 without artefacts (so far). I've been up to 1202/3602 for single runs - thought I'd start a bit lower for loops.

Only way to test is play a couple of new games for longer than 10 minutes.

Does the KFA2 GeForce GTX 780 EX OC take a full cover water block? Can't find it on ek cooling configurator. I believe it is reference, can someone confirm?

straxusii · 30 Oct 2013 at 16:27

So current settings are full power, 84C temp target, +200 core, +100 mem. Haven't really tried to push the mem yet.

So compared to my overclocked 680:

680 (+120/+400)
Batman AO: 33/94/61 min max avg
Heaven 4: 981

780 Phantom stock
Batman AO: 48/102/71 min max avg
Heaven 4: 1347

780 Phantom +200c/+100m
Batman AO: 60/113/79 min max avg
Heaven 4: 1565

So to clarify (thanks Suarez) that means the core is 1254 and mem is 3105

Suarez7 · 30 Oct 2013 at 16:32

Checked with GPU-Z what clocks the card is running in game?

My windforce at +100 core and +200 mem = 1200 core 1600 mem.

straxusii · 30 Oct 2013 at 16:38

I checked with PX, does that read correctly?

Yeah it's just when quoting your +100 figures etc each 780 has different start out clocks, for example a KFA HOF with +100 would probably put it in the 1150 core range whereas a reference 780 with +100 would only be around 1050 core if you get what I mean.

It does.

Nice core clock that, is that without any voltage increase?

Yes no volts, I haven't had long to test so I can't guarantee this is a gaming stable overclock, but also it could go higher as well as it hasn't crashed on me yet.

Mem I haven't touched though bar a token +100 so definitely more to come from the mem.

Rusty0611 · 30 Oct 2013 at 17:03

My Heaven score with 1254/1801 was around 1638. See if you can beat it

That's my utter max though. No more in the tank at those clocks even at 1.212V.

Is the new cinebench poor for testing the 780s? it only gets 10% more than my gtx570.
