hey
i got a rig running with 4x R9 280X Gigabytes. One of them is somehow below average and in general i cant get them running as fast as they do on my 3x r9 280x rigs.
The 4x go up to 710-720 while the 3x go up to 775 with the same settings.
Can anybody tell me where the failure might be. I'm running the 4x Rig with 2 Corsair XM850 GOLD PSUs.

I don`t think there ever have been any Dual-X near the 800kh/s mark.
I manage to get 745-750kh/s out of my Dual-X`s. (1055/1500/PT20/i13/cgminer 3.4.2)
Thank, I hope somebody else know a sweetspot for dual x?
Whats the best r9 280x for mining out there?
I'd say 280x toxic, doing 800+ for me.
Still have some in my groupbuy #2, check description ; )
I have 5 of r9 280x Dual-X, Its about 706khash average and 70C per GPU.
Somebody here with expiriences on saphire dual x r9 280x?
Damn. I've got 5x Gigabyte WF3 280x in a rig. TC 8192, -g 2, 1040/1500, getting 725KH/s. Best part? Undervolted to 1.019V and running off 2 Rosewill 750 Capstone Modular PSUs. Pulls 1250W at the wall (combined). Undervolt FTW!
5xGigabyte Windforce 3Gb??? how are you under-volting? Flashing the bios? To what?
Thanks!
VBE7. Wonderful utility.

Thanks for this. Both my Toxic and Vapor-X is now running above the 810kh/s mark. 
Awsome.
Awsome. vapor-x too? :O
Yep. cgminer 2.11.2 - 1155/1800/Powertune:20/1.2v
3gpus running steady at 815kh/s.
What about invalid shares? My Toxic mines with 820 kh/s (cgminer 2.11.2) but invalid shares are 30%.
My toxic show 1024 rejected out of 424651. Mining UFO. That`s not bad.
But for the tocix i`m running cgminer 3.4.2. 1130/1850/i13

i can't reach 800 kh/s
i tried 1100/1800 with tc 8193
now i'm at 767 max

Awsome. Thank you for this awesome info. I have the same cards running at 813 khash/s now at 79 C.
I'm glad I could be of some assistance... Feel free to donate to any of my addresses in my signature

2 PSU's... 1 1200W and 1 1000W
And of course 5x Sapphire Toxic R9 280x Main Specs: TC=8193, MEM=1800, Engine=1100
As for length of time, I ran for 5 hours no problems with zero HW errors, I rebooted to remove killawatt voltage meter and post pics.
Unfortunately this speed does come with a price, the cards have to run at 1.256V I can run at 765Kh/s per card at 1.2V if I lower mem to 1500 and engine to 1100. This also lowers temps from high 70's to low 70's.
