GTX 680 Owners Thread

[Risco]

So is the the card that can finally run Cryis full maxed out with copious amounts of AA and AF @ 60+ FPS?

I dunno, I've put some work into figuring out what's going on so ran numerous benches with GPU-Z and afterburner running to see what clocks are running and my card just seems clock up to 1260-1270 in most 3d apps and stays there. I've tried 100% fan, which dropped temps a lot but clocks were the same.

The fan doesn't really start to spin until 75C either, but doesn't go over 50% until 79c either..... I dunno maybe Palits bios is slightly different, with differing thresholds. I'm not going to worry about 9C if its running as expected.

*Edit* I see in Guru3d's and Hardocp's review that their card was hitting 79C+ at stock too, so I wonder if some manufacturers have more aggressive bios configurations than others?

If you check Hardocps 680 v 7970 overclocking review, they also say:

In BF3 we see that the clock speed is maintaining a consistent 1228MHz. What's even more interesting is the voltage reading. The voltage has now increased up to 1.162, but the slider only goes up to 1.150. It is possible that the higher fan speed, i.e. cooler GPU temperatures, has allowed GPU Boost to utilize higher voltages, beyond what the slider supports in the software. At 1.162v the GPU is capable of 1228MHz. This makes us think that higher voltages should yield impressive overclocks, especially if GPU temperatures can be kept cool.

Something else they discovered that was very interesting, the memory overclock can have direct effect on the gpu clocks, after the memory reaches a certain frequency the gpu starts to downclock:

The memory overclock was also a learning experience for us. We found that there was a point at which overclocking the memory hurt the total GPU Boost overclock frequency. For example, +700 memory was stable, but we found that with +700 memory frequency the total GPU Boost was no longer 1181MHz. In fact, it was under 1100MHz, severely impacting the GPU frequency. When we set the memory down to +600 GPU Boost went back up to 1181MHz. For safe measure, and to make sure we could obtain the highest GPU clock speed we kept the memory at +500, which is 7GHz total. Therefore the key isn't to overclock the memory as high as it will go now, the key is to overclock it to the line at which GPU Boost starts to degrade in performance, then back it down some, and that's your highest memory overclock.

Interesting stuff.

Bye bye Q9550. So far so good. Stable at this.

Idle temps on CPU are 39 degrees. At load 40-ish degrees.

Not constantly in my case, unfortunately. That's on an I7 2600K and 12GB.

Cancelled my order for the EVGA GTX680 I placed on March 24th since they're now saying it'll be June/July before they receive additional stock.

If you don't want to wait for EVGA (I wanted them also but in the end went with ASUS) OCUK have plenty of Gainward, Gigabyte and a few own brand in stock.

Not at £385 delivered tho

Retailers are scalping prices right now due to lack of stock. They should be at £399 tops judging by the supplier prices I can see. £379 for some of the smaller brands.

Ah right!

I login as a "business" get free shipping and don't see the vat so all the prices look good

I guess by the time things settle there will be the 4gb cards and 690 out to push the price of the 2gb 680s down?

Not with my I7 2600k and 12gb. Fast, but not enough for a constant 60FPS.

480SLI is fast enough at least, but the game doesn't scale well to multiple cores and I sometimes see a drop from 60 with one core maxed out on a 5ghz 2500K.
