cfrank78, what overclock settings you running on that GTX 670 to get 3.67???

The Gigabyte Card is out of house overclocked and runs at:

Standart Mode: GPU Core Clock 980 MHz
GPU Memory Clock: 1502 MHz

Performance Mode: GPU Core Clock 1110 MHz
Memory 1502 MHz

Extreme OC Profile: GPU Core Clock 1184 MHz
Memory 1552 MHz

I used GIGABYTE’s OC Guru II software to over clock the card.Did not raise any Voltages.

More Infos how to OC this card can be found here: http://www.hardocp.com/article/2012/07/ ... d_review/1

Kind regards Chris!

cfrank78,
My EVGA GTX 670 FTW 4GB starts the test out at 3.85 ms/sec for the first 1000 ms, than stabilizes at 3.28. Have you let your render run out longer to see if it falls?.

Im at GPU Core Clock: 1254MHz (Precision X performance log)
Although GPU-Z doesn't read the EVGA Precision X Overclock... (I Think).

Im Curious, thanks!

No it keeps the 3.67. if your card lowers the ms/s then it is getting too hot. i had the problem too when i OC too much. now it is running at a maximum of 82 degrees celsius. it begins to lower the ms/s when it reaches 95 degrees. you should check that. too hot is not good for your hardware. the ms/s ar allways stable when your card(s) are cool. if they get too hot the ms/s change after a while. 1254 is too much in my opinion. i got mine stable and cool wit 1184. it is enough. This baby has to do a lot of work in the near future - so i wanna keep it cool!

I did a render yesterday. Animation: 20 seconds=600frames and about 1 minute each frame. never came above 80 degrees. allways let your cards breath!

Kind regards Chris!

And btw - gpuz and 310 driver works perfectly and correct with my gtx 670!

I setup a custom fan curve, my 670 usually stays around 59-64. never goes above 69 which is the point at which the cards down-clock them selves.... Im stuck at 3.28 ms/sec even with the newest drivers of nvidia 310... Interesting.

I can not imagine that a GTX 670 aircooled with 1254 has only 64 celsius under full load, even with a 100% fan. A Kepler Card does not clock back until 95 degrees! Maybe your tempertures are not shown correctly?

Have you guys noticed any difference with the latest 310.90 drivers ?

Up to 60% faster performance in ray tracing applications such as NVIDIA iray and Chaos V-Ray

cfrank, I have the Corsair H-100 radiator on the CPU in a Push-Out (the top of the case) configuration. This drastically helps with cooling the case cool, as you cannot defeat heat.
I specifically went with EVGA as well, as they push hot air out of the back of the case, instead of in the case and on other graphic cards.
Plus the GTX 670 FTW has the cooling profile and design of the 680?? "don't quote me on that lol"...

The temperatures are reading correctly. In fact. when I have all three of my GPU's running at the same time on full load, the GTX 670 hits max 64-68, fans never maxed out. The GTX 650 and GTS 450 also run around 59-60. Ran it this way for 11 Days of rendering straight with no problems.

"The first thermal throttle point is at 70C, then 80C, then 85C and lastly at 95C."

But it does sound to me, that your card is running an ungodly amount of performance ms/sec, so don't ever throw that card away LOL.

Sam75, I did not notice any performance increase updating my drivers to 310.90

With Octane v. 1.0:
GTX 470 reference card - 2.42
GTX 470 non-reference card - 2.50
GTX 480 reference card - 3.06

And with Octane v. 1.02:
GTX 470 reference card - 2.77
GTX 470 non-reference card - 2.87
GTX 480 reference card - 3.52

The non-reference card is Gigabyte Super Overclock, with 3 fans. Core clock 700, shader clock 1400, memory clock 1674.
Octane v. 1.01 is the same as 1.0 speed wise.

Finally stuck my 2nd GTX 460 in workstation... 4.00 on the button with both cards running.
Using Octane 1.02 on Asus KFN5-D SLI mb and 2 EVGA 460s

Damn, do these puppies get hot when rendering for more than a couple minutes. One card was
74 degrees and the other 83!!

Does anyone know if constant up and down between 50-some degrees and low 80s is bad?...
like when doing animations or setting up scenes... I only ask because a science teacher once
told me that things expand and contract with temperature changes.

Picked up this 2nd 460 a couple months ago for $100US on eBay... There are some great deals
to be had out there on eBay and Amazon.. 570s for less than $200!! I may do two 570s and my
two 460s when I build my new system in a couple months. 1632 (fermi) cores seems like that would
put me around 10-12 M/s on benchmark... not too shabby. And very, very inexpensive.. for that
setup. (edit: this is used GTXs I am talking about -- don't look for new 570s for under $200)

The Geforce website says the max temperature of that card is 104 degrees Celsius.
The card should be safe in the 80's. I wouldn't let it hit 90 in my opinion.

Try a custom fan curve with EVGA precision, or MSI afterburner.

My GTS 450 use to run 80+. I took it apart and reapplied thermal paste and now it runs in the 60's.
Although when you stack cards directly on top of each other, it makes them both run hot. Other than that, if your motherboard allows it, try spacing them out. Even if you have to move one down to a PCI-E X4 slot. It won't make a difference in speed with octane.

I ran Octane for 11 Days straight. These cards are designed to take a beating. If that card blows up in the safe zone from heat, RMA it.
