MSI R9 280x Battlefield Edition can't go over 680Kh/s

[saykor]

Hi I have 2 from this cards: http://game.msi.com/special/amd-radeon-battlefield-4-bundle

If I change GPU Clock or Memory clock different than default values ( 1020/1500 ) Kh/s drop.

My mining setting is:

cgminer.exe --scrypt -u saykor.miner1a -p x -o stratum+tcp://stratum.forkpool.com:6444 --intensity 13 --worksize 256 --lookup-gap 2 --thread-concurrency 8192 -g 2 --gpu-engine 1020 --temp-target 76 --temp-cutoff 90 --auto-fan

OS: Win7 64bit
4gb ram

Can someone help me

Thank you in advance

Thank you, but we not talk about GAMING 3G OC Edition here.
As I say if I change gpu-engine or gpu-memclock hash rate drop. So configuration what they need to be is not helpfull when hash drop if change them.

Either way, i at one point had a setup with your exact cards and if i was even a mhz outside of that sweet spot of 1040-1070 on the core i would lose serious hash.

The rest of your config is good.   You may want to look into flashing a more optimized bios.

If I flash the bios what will happen with my warranty? The cards is on 2 months old.

I would think nothing.  

You should have 2 bioses on that card anyhow...just flash new bios on the second bios chip.

Before you do any sort of flashing, read this thread: https://litecointalk.org/index.php?topic=12369.0

here's my config for the 280x's (not the same brand). Also do you have a monitor connected to either of them?

cgminer.exe -o stratum+tcp://mypool:3337 -u lunswor.rig1 -p x --scrypt -I 13 -g 2 -w 256 --shaders 2048 --auto-gpu --temp-cutoff 90 --thread-concurrency 8192 --gpu-memclock 1500 --gpu-engine 1080

I have 2x msi 280x GAMING 3G OC Edition that works perfect with this setting.
But drop down to 580kh/s for Battlefield Edition

Thank you. I will read the thread.

What power supply?  Gold or better quality is important.  What's your cooling situation?  Open air rig?  Should be.  Get a box fan.  I don't run the temp commands in cg...  just let the cool air circ with box fan.   If your vrm is pegging you will not get sustained superior performance.  You really shouldn't need to mess with flashing the bios even though it can be fun.  You should use gpuz and report your temperatures over a 15 minute time period.

Set the GPU to 1045 and the Mem to 1500, does the trick for me,. 740+ khash
