XFX 7870 - couple things i'm not real happy about

post #1 of 33
Thread Starter 
started running heaven and it got smelling a little hot. don't you love that resiny smell? smells like victory



this is why you don't sandwich GPUs. of course XFX did not send a long enough crossfire cable to avoid this


anyway, my new 7870 (installed on top) has 4 heatpipes while the one i got a month ago has 2 heatpipes and a smaller heatsink





do you think there is any way to get a replacement heatsink or card? the new design is clearly superior. PCBs are different too. i guess they realized the old design was crummy and did a revision. kinda sucks i have a gimped card.
also there are no VRM temp sensors on the older card. missing some other sensors too that the newer card has


what should i do here? i hate to just sell the older card because i will lose money on it

787A CDFC
old: VJ.0
new: VA.2

Great piece of info man. I just saw your post in another thread and decided to look at your recent posts and found this one. So glad I did. I didn't know there were two versions of the CDFC out there. Just checked mine and I have the A2 version. I knew when I saw your sale post that the printing on the red metal looked odd. I didn't remember all those characters on it.

I soon plan to crossfire and now you've given me some info to look out for. I'll make sure I get another A2 version. Thanks for the post.

So you say removing the red metal actually decreased temps? WOW.

I know this doesn't help you but this is why I've always chosen Sapphire for AMD/ATI. Always of the highest quality.

From what it looks like the first card is a 7870 Black Edition

Red metal strip advertising 7870 instead of 7800 series
4 heat pipes - http://techreport.com/review/22705/xfx-radeon-hd-7850-and-7870-black-edition-graphics-cards
PCB matches the one on the Black ED - http://www.legitreviews.com/article/1967/1/

Can you please help me check if your new one runs at 1000 core and 1200Mhz memory at stock
I just purchased mine last Thursday and got a VJ.0.
If the VA.2 is a standard 7870 Ghz ED I'm going back and demanding one of those

PLEASE

that is funny that you got 2 different versions i have the core edtions and they are the same version but different heat sink on them and they both run the same one thing i did find interesting is that i removed the shroud and the red metal peice and it changed nothing for heat on my cards at all i found that leaving the shroud on and having a case fan blowing air at the cards helped the most lost 5c on the main card and no effect on the second card at all lol but as for your issue with the heat because of how close they are i hear this complait alot that is why i bought the Crosshair V board they gave lots of room for the video cards ill take a picture and post it
