GTX 780 Owners Club

[Wucked]

Ah Mah Ghad, not another 780 post FFS

Post here with your 1st impressions if you like

Mine arrived this afternoon...

Aesthetics of the card with stock cooler are lush. I love the glow of the Geforce logo on the side of the card, really nice touch.

My Rig:
Cooler Master HAF X
i7 920 @ 3.8Ghz HT Enabled (H100i) - Mid 50's°C gaming
6 GB RAM
Cruicial M4 256GB SSD

I pretty much immediately started up Precision X 4.0 (OcUK is a bad influence ) and worked my way up to a safeish overclock of:
Power Target 106%
Temp Target 94°
+150 GPU
+100 Mem
Giving me...
1136 MHZ GPU Clock
3105 MHZ Memory

So far completely stable.

With two monitors (1440p & 1080p) its idling ~38°C. With the custom fan profile I use, in BF3 it was sitting steady at a 58°C (idk ambient atm) at the above clocks. I'm impressed with the stock cooler, really nice bit of engineering. The fan was audible but not intrusive, sitting around 55% at the above temp under gaming load.

Only played BF3 so far, Low settings with Ultra Mesh and a bit of AA for competitive play. With vsync at 1080p on my Asus 144Hz screen it was sitting steady between 100-144 FPS. Gameplay it amazingly smooth, noticeably more so than my 680 was. In terms of frame rate it hasn't been a major upgrade tbh, but its a much smoother over all experience so far. I'll update this later after I've tried a few other games out.

Its suits competitive play which is all about smoothness and clarity, but I will test on ultra at some point. I get what you're saying though, but I think that could be down to the CPU and modest OC I have. I'm interested in hearing from 780 owners on newer gen CPU's with higher OC's, I'm hopeful their minimum's will be higher. CPU is the next upgrade I'll be wasting money on in the next month or so and I'll be updating this post when its done.

 

[Wucked]

Am i right thinking that once it hits 70c, then it will downclock itself? Im sure this happened to my other card.
Just wanting to clarify before i experiment.

It depends what the power target / temperature target is set to (some voltage too I think) and how your fan profile is configured.
Mine is set to stock volts, 94°C temp target and a fan curve linear to the temp. 30°C = 30%, 50°C = 50%, 80°C = 80% etc. With those settings in game a min ago it was a steady 58°C @ 58%. Quite high fan speed really, I could knock it down some easily. Anyway, I had Precision X running on my second screen and there was no throttling. I wouldn't expect to see any until it reached the temp target, which it's nowhere near atm.

 

[Wucked]

I doubt your cpu is causing much of a bottleneck if any. A guy on here is running the same cpu with dual titans. His does bottleneck those cards a bit but that's 2. Bf3 likes hyper-threading so make sure you have that enabled.

Its on but good point, I'll update OP with that.

 

[Wucked]

The reason I mention it is that I average around 100 fps with 2 560 tis in sli at 1080p on high. I'm running a 2600k at 4 gig so that might help as well. I will also mention that on bf3 you can create a user.cfg file in your Bf directory to limit your fps to 144 then you won't get the dropouts from vsync.

That's interesting, TY. I'll take a look at the user.cfg file.

Still reading up on the variables and tweaking, but so far with the following I've seen min FPS jump to 115.

GameTime.MaxVariableFps 200.000000
Render.DrawFps 1
Render.DrawScreenInfo 0
Render.PerfOverlayEnable 1
Render.PerfOverlayVisible 0
RenderDevice.Dx11Enable 1

RenderDevice.ForceRenderAheadLimit 1
Screenshot.Format png
UI.DrawEnable 1
WorldRender.DxDeferredCsPathEnable 1
WorldRender.SpotLightShadowmapResolution 256
WorldRender.FxaaEnable 0

No put much effort in yet, but already got:

Power Target 106%
Temp Target 94degrees
GPU +180
MEM +120

Giving Max boost of
Core 1175.8MHz
Mem 1575.6

Max temp 68degrees.

Which app were you running and what % was your fan on at 68°C?

 

[Wucked]

Pick one.

ESL. Its not exactly up there with CS:GO or Starcraft, but I like it. So you're welcome to have some cheese with that somewhere else, meanwhile I'll keep playing what I enjoy.

 

[Wucked]

Sorry to hijack the thread but maybe you can wrap this up for me possibly. Im totally interested in possibly purchasing a 780 in the coming weeks but was bamboozled by the different variants in clock speeds on some. (Mainly the EVGA ones) Is this just the fact that some come with different BIOS's set to a higher clock speed and that most will be able to clock to that degree anyhow?

Any info on that matter would be appreciated!

The EVGA is just clocked higher and sold that way. You'll find that all the cards will clock to that speed, and probably a lot higher.

^^^ Nothing special about the initial cards as far as I know. Can't speak for every card but mine and the other stock cards I've read about so far have been good overclockers as standard.

 

[Wucked]

why is the 780 "smoother" than the 680??

GPU Boost 2.0 and just a more powerful card I think. I haven't exactly fallen off my chair in amazement, but I'm definitely impressed and happy with my purchase.

 

[Wucked]

Would an i7-920 be a bottleneck for a GTX780?

Contemplating getting one but wondering whether I should wait for Haswell and get a complete system rather than just buying a video card as I'm also currently using an i7-920 (albeit at stock speed)?

It depends on the game I suppose, but so far no, my 920 doesn't seem to be bottlenecking it.

 

[Wucked]

Cant wait for MSI 780 Lightening Power!!!!

Hopefully I will test one at Computex and let you guys know how this goes!!

Damnit 8, you get all the best toys I was sorely tempted to wait for custom cooled kit, but I've got to say the stock cooler is really nice.

 

[Wucked]

Just thought I'd post a few pics of the 780 as stock and after fitting a water block. Apologies for the number of pics but thought some will find them interesting in this thread. Also apologies for the quality. They were taken with my phone (Lumia 920).

Snip*

Overall, I am thoroughly impressed. I really don't miss the 2 670s. Also the minor stuttering the sli setup used to occasionally give (in wow raids) has disappeared. I am tempted to only ever game with single GPUs from now on but with the most powerful single card I can afford.

Nice rig

I agree and its what I've done for a while. For overall smoothness, which I value more than outright FPS, it is atm the better option. I'm probably going to go custom loop with my next CPU upgrade, looking forward to having no more worries with temperature.

 

[Wucked]

Seeing people posting quite high temps here.

Still +150, +100 atm and in game it hits 60° at 60% fan speed, not had it go above that yet. Perhaps I'm not pushing the OC hard enough for the higher temps, or maybe differences in case cooling.

 

[Wucked]

I wouldn't say massive, but you'll definitely notice the difference. Its a lovely bit of kit.

 

[Wucked]

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.
