I have 4x GIGABYTE GV-R928XOC-3GD REV2 Radeon R9 280X 3GB that I have been using mining zcash. Is it just a matter of flashing this rom in the via atiflash that is in the original post? That's it?

Depends, check which memory type you got with each of those GPUs.

Use GPU-Z. If you got Hynix for all of them, flash with the Gigabyte 7970 Hynix ROM posted above.

Do one GPU at a time in case something fails.

I have 4x Gigabyte 3GB all with GDDR5 (Elipida). GPU Clock 1100MHZ - Memory 1500MHZ

I have 1x VisionTek 3GB with GDDR5 (Samsung). GPU Clock 1050MHZ - Memory 1500MHZ

Thanks!

For your Gigabyte 280x try

Its slightly undervolted, so increase voltage if you have instability and slowly increase to 1100Mhz/ 1575Mhz from 1000/1500Mhz stock.

Elipida is always slower and that card only runs at 108Sol/s for me @ 1000/1500. Try 1100/1575Mhz and if its stable you might get up to 120Sol/s.

For your Samsung, I got nothing.

I have flashed the rom you mentioned above with atiflash to one of the Gigabyte (Elipida) cards. I am getting 95 - 97 H/s. When you say "Try 1100/1575Mhz" do you mean modify the rom itself with VBE7.0.0.7b.exe to match those numbers, save it, and reflash the card with the new file or do you mean set those settings in MSI Afterburner? Forgive me for my lack of knowledge this whole mining thing is new to me and I am trying to learn. Thank you! Anything I can do to the bat? Here is how it looks now and thanks!

GPU_FORCE_64BIT_PTR 0
GPU_MAX_HEAP_SIZE 100
GPU_USE_SYNC_OBJECTS 1
GPU_MAX_ALLOC_PERCENT 100
GPU_SINGLE_ALLOC_PERCENT 100
ZecMiner64.exe -zpool zec.suprnova.cc:2142 -zwal user.0 -zpsw pass

You can do it in Afterburner since you are allowed to overclock, you just can't underclock there you would have to use VBE7.
