FurMark trouble

[virtualTune]

Hello folks,

I just read an article on GPU overclocking and figured I will give it a shot with my Gigabyte GTX 670 OC Winforce 3. (http://wolframpc.blogspot.de/2012/01/graphics-card-overclocking.html

)

 

So I am currently at 6230MHz Memory and 1060MHz Base Clock. First time I ran Furmark Benchmark (1min) at 1080p without AA I got a relatively high score with 2959. Of course I went further, but I eventually got back to 1060, everything above gave me slightly worse scores. Now my problem is, when I re-run the benchmark, my score keeps going down 2944, 2929,... even though I am not changing any variables. 

 

Can someone explain this phenomenon to me?

 

Thx!

any kind of background programs will affect scores as well as having more then one monitor attached can makes the scores do some weird things to, the score is rarely if ever going to be the same

Furmark isn't that good for testing overclocks.. It mainly makes heat. Try Valley, Heaven, Catzilla, 3DMark and of course the test it with what you're actually doing.

 

 

 

 

 

 

Why are people still using Furmark :s

Like i said I am new to the area :D

 

Well I use 2 monitors and I was running multiple monitoring programs alongside chrome. It is just strange that they consistently go down. 

Also, I have noticed when I run CineBench (I mainly work in Cinema 4D) my CPU goes up to 4.21GHz, but with FurMark it goes to 4.32 GHz but stays below 40 degrees Celsius. 

 

I'll use 3DMark next. 

 

UPDATE:

Since I can't get my hands on 3D Mark, I used Unigine Heaven. First thing I noticed is that the 1060MHZ Core Clock that were stable with FurMark, instacrashed in Unigine. At 1040 it was stable again, but I got better results at 1030. I also bumped my Memory to 6240MHz. Everything above is giving me bad results. 

Settings: OpenGL, Ultra, no Tess., no 3D, no Multimonitor, AAx4, @1080projectors

Score: 1099 FPS: 43.6 (26.5, 92.6)

 

I just cannot crack the 1100! oh well, lets see how this works with games and 3D software. 

 

One more thing: I don't have my CPU at a constant speed, so I figure that also influences the results ever so slightly. It jumps around between 3.5 and 4.3 GHz. I'll do more testing tomorrow at a constant 4.3 and see if that helps.
