Bitcoin 6950 flags

just started mining today ...(and yes i know dont start !!! but im still going to do it
i got two xfx hd6950's using phoenix or guiminer the temps are very hot 102c on one card and 92c on the other and im only getting about
240 mh/s out of them most disappointing

windows 7 x64any ideas chaps ?!?! as i was looking to overclock and push these to the max...currently they suck ! lol cheers onis_uk

Hmm I dont know.. I've only been in the game for about a week. I don't have AC in my house and hits hot here. but I still can keep them under 80 degrees fully overclocked usually. I do have big fans on them though. I use linuxcoin though. Has everything you need for the linux noob to get up and running. All can be run from a USB drive.

I have 8 visiontek 6950's

Yea, I have a HIS 6970 that runs @65C idle and jumps to 90C+ within 10 seconds of mining.
I believe it may have to do with poor thermal paste from the factory.
I'm going to scrape the junk off and apply some real arctic silver.
Maybe that will help.

While I'm not certain of your issues, I too have a pair of 6950's running, so maybe my setup will offer you some insight:

One card is current slotted in the top, the other card in the bottom slot, with an empty slot in between them for better airflow. The bottom slot only offers PCIe x8, but this is perfectly fine for both mining and gaming.

I'm using a PCI output fan directly above my top GFX card to pull heat out of the case and prevent heat exchange between the GFX and CPU. Additionally I am using a AeroCool Shark 140mm case fan as an intake fan bringing in air directly onto the GFX cards from the side of my case, where there is about a foot of open space before a wall. My case does have front intake fans and top output fans but they run at very low speeds and don't really effect GFX temps due to their positioning.
