why my 4x280x powercolor only 1582h/s (core 1100 mem 1250)

Hello!
I use GPU Miner v5.1
I have 275 shares of the dev fee, and 612 shares all, on some time.
Dev fee is  44,93% !!! It's not 5% fee!!!

What is it?!
 

I don`t know if this help in performance boost but from previous knowledge on my R 290 farms was set option
GPU_FORCE_64BIT_PTR 1

Miner reports memory size that it can use, not physical memory size. AMD driver does not allow OpenCL applications to use all memory.

It's this way with the xpm miner too.  I'd be curious to know.

Hi great job on the miner! just a quick question, when I start the miner, it says I have 3GB available ram on each card, but they are 4GB cards, why is that? is it affecting mining? (im getting about 1800 from the 3)


Cards available: 3
GPU #0: name: Hawaii, 3072 MB available, 40 units
GPU #1: name: Hawaii, 3072 MB available, 40 units
GPU #2: name: Hawaii, 3072 MB available, 40 units
Total cards: 3


my match file starts with:

:GO
setx GPU_MAX_ALLOC_PERCENT 100
setx GPU_USE_SYNC_OBJECTS 1

thanks!

It's within the bounds of normal if you are running at stock speeds and have elpida memory.

p.s. 4x290 total 2474 h/s is normal ?

There is no option on the miner itself, I am using Afterburner to control my fan speed to prevent overheating.

to much pages for reading. One simple question. How i can control fan speed that would prevent overheating?

Take pool.bat as start point, start it to check that it works, then change only pool and wallet addresses.
Last time I saw this problem when some guy specified long hyphen instead of short one.
