Didn't realize my MSI 290x cards were actually all 7970. But the 290x recommended settings work great with very little tweaking and I did all this work so I'm gonna post it here cause i just don't care enough to look for the correct thread to post it under. Meh.

I do not think the cards in the OP are BF4 Eds.

I can't provide anything about the ram as i have since sold these cards off for 270s.

270s make quite a bit more sense in terms of performance / watt!

What hash rate are you getting with the 270s? and which brand of 270s did you get?

Sorry for digging this thread up, but just noticed this question:
MSI 270s and Asus 270s which are collectively doing ~470khs @ 1100/1250/1.1v @ i19.

I concur with these settings. 1100/1250 but i use xI @ 4. and get ~480khs

Not if you also calculate the cost for additional hardware like PSU, motherboard, RAM, CPU, USB and whatnot.

I get 745 max on my MSI. Tried this guy settings - less than 600Kh/s

These MSI cards may be special. They do use Samsung ram, and not elpida or hynix. There's a good chance the MSI card bios may having tigher memory timings etc which allow higher hashrates.

The only other 280xs i know of that hit this high are those Sapphire Toxic 280xs. I would be highly interested in knowing what brand of ram they use.

can you show your memory @ vbe7 or tahiti gddr5 identifier
