YES!....please   

Interesting, so what are you VRM temps like?

I noticed that my fans by default were spinning quite slow around 45% so I upped the fans to 70% and that got the VRM temps back to like 85 degrees C.

Was yours the same card as mine? Sapphire Vapor X?  And was the power jumping around all over the place as well?

Config is the same for both cards

setx GPU_MAX_ALLOC_PERCENT 100
setx GPU_USE_SYNC_OBJECTS 1
cgminer --scrypt -I 13 -g 2 -v 1 -w 256 --lookup-gap 2 --shaders 2048 --thread-concurrency 8192 --temp-cutoff 90 --temp-overheat 85 --temp-target 70 --gpu-memclock 1500 --gpu-engine 1060 --expiry 1 --scan-time 1 --queue 0 --no-submit-stale -o http://ltc.give-me-coins.com:3334 -u -p --failover-only -o [Suspicious link removed]:8888 -u -p

Yeah I already did flash the bios and that was the guide I followed, looking at the bios version it looks like the newer version is the bad one (015.041.000.000.000000) so flash with the old one (015.039....) but as mentioned it wouldnt boot so had to revert to the old one

Hi

I have recently setup a rig to mine litecoins and various other altcoin, I started with one Sapphire Vapor X R9 280X which worked fine and I easily managed to get it to around 730 kh/s and undervolting led to my system using about 315 watts. All was good so I decided to buy another of the same video cards, finally tracked one down and installed it but using the same settings led to different results



The new card seems to run hotter and get less kh/s it's really letting the team down.  So I started looking at what may be different about the two cards and found they had different two different BIOS's and the only other difference I could find was the part number on the card itself,  The good one part number is 299-5E210-004SA and the bad one is 299-6E210-004SA



So I thought it must be bios version so after much googling and not finding much I pushed the button to enable the UEFI bios and wrote over it with the bios of the good card but after that it would not boot up so I had to revert back to the original bios.

So I looked into it further and noticed some interesting things in GPU-Z



I noticed the GPU core clock is very up and down and the VDDC is all over the place also the VRM temp is at 108 degrees!

I was hoping someone with more knowledge of this stuff would be able to help me out is this card faulty?  Should I be taking it back to the shop just got it a couple of days ago.  I don't like my chances on getting a replacement though.
