Title: Comparison between XFX Double D R9-280X-TDFD and MSI AMD R9 280X
Post by: kartiksibal on February 24, 2014, 07:40:51 AM
Hello,

I was looking forward to make a mining rig but am confused between XFX Double D R9-280X-TDFD and MSI AMD R9 280X. I am not able to understand as to which has a higher hash rate and would be more durable and profitable for a long term use. Would be glad if ya could help me.

Thanks

The XFX are shunned by coin miners for giving low hash rate and using low quality components. Not sure how this particular model will behave.

I've read some MSI are voltage locked.

You have to undervolt and otherwise tweak your cards with custom bios, bin files and miner software, for most hash rate OR best efficiency (depending on how much you pay for power in your region), so perhaps those 2 cards are bad options. But then, I'm talking a bit out of my ass because I don't have them.  :P

You are the dude that wants to get 18 cards, right? Perhaps you should order 1 XFX and 1 MSI upfront to test, and then grab the one that gives best results.

I am looking for the best available options actually. R9 290 was going out of budget, so didn't go for it. Suggest me something good in 280? I'll see if i can manage to get it in India.

Thanks

I've seen people reporting good results with ASUS and Gigabyte 280x.

I have VTX3D 7970 and 280x (managed to get them at 235 and 218€). They are decent for a budget brand, even if the voltage oscillates and don't allow for very agressive undervolting and power savings. IIRC I get 760 Kh/s at 1060 Mhz core, 1600 Mhz vram and 1.081V after BIOS mod and sgminer, but I'm not mining scrypt atm
