[Official] AMD Radeon HD 7950/7970/7990 Owners Thread - Page 1602

post #16011 of 38701
Just installed my 7950 vapor-x and have to say I am disappointed at the noise and the heat. Unigine Heaven run raises the temps to 85C when the whole system crashes and fan blows at 70% which makes really nasty noise.. not sure whats up with the card. I've not even used the overclock button.

Cooling is top notch, should be just as effective in a traditional case with good airflow. And to round it off it's 2.5 slots.
Big thumb down for locked voltage control! mad.gif My PCS+ 7950 is free to set the voltage and I really like it! Stock voltage made it a bad OC, but with my own set voltage it OC great, so I think I will have to look for a Powercolor PCS+ 7950 or a Vortex II 7970 redface.gif

Thanks for sharing the info! Atleast I will not buy that card and not be satisfied thumb.gif

what is your cabinet and CPU . also is your GPU fan speed on auto. 85c is really bad.

http://www.techpowerup.com/reviews/Sapphire/HD_7950_Vapor-X/32.html

the vapor-x should stay below 70c even at 1.1 Ghz. first test on an open bench to rule out a faulty card. if temps under load are around 65c on an open bench then it might be worth looking at your case cooling. if temps are still high in an open test bench just return the card.

I found the culprit. When the amd's gpu boost was working it also increased the gpu voltage up to 1.25v which caused heating up. As that happened card also hit the power limit and lowered the gpu clocks as well resulting worse fps and massive heat. I turned on the cards gpu boost button which essentially disables the amd gpu boots and increases the clocks to fixed 950MHz. After this the gpu speed remains constantly at 950MHz with 1.056v and temperatures below 65C with auto fan. Seems amd's driver based gpu boost needs still some work.

*sigh* Technology... haha

I wouldn't necessarily blame AMD. If you search this thread, it seems to be more on the manufacture about locking voltage control. Atleast by my opinion. If you can, return it quickly for a Sapphire Vapor-x or MSI TF3.

Well, I bought this card because it has the 6+8 pin power connectors and was only $289.99 after MIB.

 

I got some voltage control in Asus GPU Tweaker, but that application wouldn't raise the clocks or memory past certain points. (1100mhz core and 6300mhz mem). Which was also disappointing.

Guys is it normal to have massive Vram usage in CFX?

I remember someone also else had massive Vram usage in CFX, performances are ok, but its little weird.

Just set up 2 different profiles in MSI AB or Trixx or whatever OC software you use. Once for the 2d applications, and one for 3d. I know with AB you can have it automatically swap between the 2 profiles. I set my 2d profile to 500mhz core, 685mhz memory. No issues, and it keeps my idle temps down.

whats the benefit of voltage control? i have slightly unstable cards....i've always considered lack of power.... should i look into this as a solution?

I know that, problem is that i seeing Vram usage over 2000 MB with CFX enable, with CFX disable i am getting about 1000MB Vram usage.
