Hello all. thank for taking the time to look at my post.
I have two(2) XFX HD 7770 .. one is a black ed. and the other one is a 1gz ed. With the DD cooler on the two.
So my problem is that the 1gz model has missing stream processors. only 512 and not 640.also it only has 32 TMUs and not 40.. I do run them in crossfire and it a hit or a miss.sometimes it will crash on starting a game or hr's latter. sometimes games look like they are on fast forword and then I get a black screen. But when i run each card on there own they run just fine.. so Im not sure whats going on. Its a 7770 the PCB looks just like a reference card "1-DVI 1-HDMI 2xMINI display" even tho the rear I/O only has a hole cut for one of the mini display there is really 2 you just cant see it.. Its just odd that a 7770 would have 7750 numbers.
The PCB model stick says ( FX-777A-ZDF4 ) so it would be this one. http://www.techpowerup.com/gpudb/b1687/xfx-double-d-hd-7770.html
but that one has 2xDVI 1-HDMI 1-Display port. But the bios says ( 015.013.000.002.000000 ) that would be for a core or a black. I will post some pics.
