Topic: R9 280x Hash rates (Read 31231 times)
So would you guys recommend an R9 280x over a Sapphire HD 7950 card?
i have 2 sapphire r9 280 x vapor, only 600 KH/s max.
Try to play with the settings, what is your clocks?
1020
Most important for scrypt is memory overclock.
You have to find right core/mem clocks to achieve best results. What is your voltage? Can you change it?

Vapor-x r9 280x, easy 730-740 kH/s
Setup Sapphire trixx vdd voltage to: 1181 (GPU-z shows VDDC voltage: 1.115 V, going lower, system will become probably unstable).
cgminer (put temp. settings as you wish...): --shaders 2048 -g 2 -I 13 -w 256 --auto-fan --gpu-memclock 1485 --gpu-engine 1080 --gpu-powertune -20 --expiry 1 --scan-time 1 --queue 0 --no-submit-stale
try it, and report
600khs for MSI 280x using only 70watt of power
UPDATE: with some more tweaking and a little OC, managed to squeeze 800KH/s from my Asus 280x DC2 TOP
he pushed his card to 1150 at least, with I 13 -g 2 and thread-concurrency 8192
i wanted to config mines so post your config Flunder707

Sweet spot for 280x and high core clock for 7950, atleast for mine

Very nice setup. Toxics are great cards.
Sapphire 280x, 640 KH/s, but only 150W 
sapphire 280x vapor x getting 700khash and temp hovering around 68-72
These are basicly oced 7970 cards, so 740 is a must for them.
sapphire 280x dual-x getting about 730-740 per card temps are at 68-70
My rig with 2xSapphire R9 280X Vapor-X runs at 2 * 650Kh/s
And the rig with 2xSapphire R9 290 runs at 2*700Kh/s
OS: Kubuntu 13.10
Driver: 13.11 Beta v9.4
cgminer 3.7.2

Finished updating my rig... new pics, specs, config, etc can be found here...

Not bad. I got a gigabyte 280x and do about 740.
Funny, because back in November XFX was one of the underdogs people didn't want.
Nice performance. Post your config please.
