First of all, I'd like to apologize for being a bit too late to chime in on this conversation tongue.gif

I can verify from personal experience and testing that kmac's theory is 101% correct, at least for my card anyway. I found that I got the best sub-1390-memory score at 1250.

Here are the 3dmark11 runs at different memory clocks. Everything else including the number of background tasks running and core clock was left the same throughout all tests.
Warning: Spoiler! (Click to show)
Sorry for spamming you guys with so many links but I wanted to be thorough. Now, onto real world performance, I see absolutely no difference between 1250 and 1390 in BF3. So better to leave those memory clocks at stock or only slightly above stock, well, according to our (kmac's and mine) findings anyway.

im using the ccc 12.11 beta
Are you sure the fans on the card itself are running? I had a problem once with a PSU that wasn't supplying power to a HIS 7850 I owned once. Make sure you connect BOTH connections to the card.

I've put my card through some hard times and never seen temps you're talking about.

yes both cables r connected, if i go to amd overdrive section and turn on the fan in manual mode and set it at 100% i can hear the fan working at max speed wha-smiley.png

Sounds like maybe the heatsink isn't properly seated on the gpu itself. You should inspect the card and see if you notice anything out of the ordinary where the heatsink makes direct contact with the gpu. Seems as if the fan is operating properly so you might want to get some thermal paste and reseat the heatsink.

i think ill have to do that, my card is only 5 days old, but i already tried a fresh install of w7, w8, removing dust from system and everything is the same, i have been wondering to set a lower Voltage till xfx gives me a solid answer, i realize that i can get 91°c if i turn off AA, AF, TESSELLATION and turn on vsync in unigine heaven and 75° playing league of legends, but those 103° playing farcry 3, 3dmark11 freaks me out and in other hand i dont know if it could b a mobo related problem, the cards says "pci-e 3.0" and my mobo says:

GA-P55-UB3
1 x PCI Express x16 slot, running at x16 (PCIEX16) (Note 2) (The PCIEX16 slot conforms to PCI Express 2.0 standard.)

Does anybody knows if i can get some heat reduction in case that i set a lower V in afterburn, could it be a mobo related problem??

thanks.

Once again I"ve said a few times that you can offset the loss if you can keep INSANELY high mem clocks, which is what I would call 1450....

Is that even game stable?

Furthermore, you have yet to show a comparison between that and 1250 with the core clock the same. So for all we know that extra bit might only gain you 100 points at best.

+1

My card starts Grey screening at 1400 mem so i can't test at values over 1400. And why didn't you keep core at 1200? Lol

So I just received my Diamond 7850 the other day. I'm having this really weird issue with it. First off my monitor gets these faint flickering horizontal lines across the whole screen when anything 3D is being displayed (Games and ATI tool). Second thing is my microphone on my Asus Xonar DG is giving off this high pitch whine at the same time. This whine is very loud when using the rear jack on the sound card and is very faint on the case's audio jack.

Here's a link to the graphic card: http://www.newegg.com/Product/Product.aspx?Item=N82E16814103211

I'm using the driver 12.10.
My monitor is and LCD VGA only 1680x1050. I'm using a DVI to VGA adapter. I've tried a few different brand adapters but they all have this flicker.
Sound card has the latest drivers currently on Asus's website.
The problem does not exist when using 2 Nvidia 9600GT's in SLI.
