post #321 of 847
so it seems the HIS H795QMC3G2M Radeon HD 7950 3GB is the way to go http://www.newegg.com/Product/Product.aspx?Item=N82E16814161429&nm_mc=OTC-pr1c3grabb3r&cm_mmc=OTC-pr1c3grabb3r-_-Video+Cards-_-Hightech+Information+System+Ltd.-_-14161429?
Does it qualify for the 3 free games?

thanks for all the help btw, I lose my **** when I try to make sure I acquire the best hardware for my money.

That card looks awesome. Only question I have about it is how well the Elpida IC memory on it will over clock. The Hynix over clocks very well for me.

Does the VRAM modules run hot? Is it so necessary to put heatsinks on the top of them?

Bummer. CAn you post photos of the PCB of it? Is it an older model? It thought all the new ones were using reference HD7970 PCB.



PLEASE post some photos of the PCB. smile.gif

My ram got very hot to the touch. Before I water cooled it with full cover block I used a Swiftech MCW82-7900 gpu only block with the stock 1 piece heat sink that covered all the vram and the memory VRM.


This is what it looked like with the stock PCB heat sinks and the Swiftech MCW82-7900.





I think SApphire did a good job by separating the main VRM heat sink from the RAM/memory vrm heat sink. I think the heat from the RAM and the VRM gets trapped in the heat sink and by separating the heatsink the ram and VRM can cool down faster.


Since I put Fujiply xtreme thermal pad on my VRMs and vram my card over clocks better and the VRM temps are cooler. The ram gets very hot to the touch. Felt hotter than my VRMs.

I think the best way to cool the VRMs and vRAM is either to put a well designed water block on them with high quality thermal pad or put individual heat sinks on each vRAM IC and VRMS.


My card with fujipoly xtreme thermal pad and Coolaboratory Liquid Pro on it. Water cooled with Heatkill block. Lots of photos.

Also I have screwed up on BIOS flashing on both positions and have done a blind flash without display. A little scary but can be done as long as you know the ATIflash commands which are simple.

Its not hard to flash just make sure you have a working bios on at least 1 switch at all times to avoid problems.

ok then i have no other choice than to try flashing out... i thought also if you have two bioses what could go wrong if flashing fails?! I never seen in the internet someone trying to flash these modified club 3d hd 7950 to hd 7970, who knows as i said above maybe miracle happens loll wink.gif) Can you pls provide me with some HOW TO use atiflash ? i need a good tutorial cuz never used atiflash before?! thnx

I got my HIS IceQ2 boost and everything seems to be running fine this time. Had a ticking noise before so I RMA'd it. Currently the highest I can get the card is 1125/1500 @ +20% Power control. I found that MSI afterburner does not let me overvolt this card at ALL. It gets really unstable and flickers horribly. Decided to just overclock in CCC. I might try out the HIS software that came with the card to see if I can get er any higher. What is a good 'average' people are seeing the the 7950 w/7970 pcb, in terms of overclocks?
