Hi!
Stock, or modding bios is it the cards?

Ok I feel like a complete noob but I have been having a hard time finding out whether I have AFR or BFR mem chips in it. GPU-Z doesn't tell me the info, ATIWINFLASH doesn't give me that info using the -ai switch. What's the easy way to find out without having to take the cooler off and look at the chips themselves?

Looking for anyone with a MSI Frozr 7970 bios mod to lower voltage and maybe get an improvement in speed if possible.

Please am about to build a rig of 5x R9 270x for zecash miner

please what's the stock hashrate for R9 270x on zcash using the latest claymore miner v12.4

You can made it youself. Just search via google "Tahiti bios modding". I can made it for you. Give me your bios rom, I make mod.
