The funny thing is when I turn off the .bat, and I restart it, the khs is diff..

lookup gap should be 2, and tc 8192. lowering tc or tc +1 method only works for 290 and 290x.

i do think the settings are all messed up.. just use 1080/1500 as baseline TC 8192 or 16384.. and see what happens

TC+1 can work for 280x but dunno why temps go haywire..

if something is wrong, it isnt working lo

hashing fine, but creeps up a few deg C.. which is not so good when you got alot of cards..

i see. i tot suddenly shoots up to 90C

it'll happen if u put 3 GPU inside a PC case..

No good, 525 only..

add 1 to the tc n see? 8193 or 16385

seems like adding 1 into tc im getting better result.. so can i keep on adding or just tune the core clock to get the optimum hashrate?

after a certain period, the gpu load started to drop by itself, and hashrate also dropped.. how do i set the gpu load to max?

280x 525 hash ?
do u try to google about your card to get the best config ?

put the at the .bat to get maximum load

setx GPU_MAX_ALLOC_PERCENT 100
setx GPU_USE_SYNC_OBJECTS 1

so it will be looks like this

this is why, it sounds weird.. people easily reach 700+++, and im barely touching 700..

yup, i have that parameter in my bat file.. yet still dropping.. ever since my tc changed from 8192 to 8193..

tc 16384 caused driver to crash..

mine is at 740 kh/s

tc - 8192

is there a difference?.... increase higher tc means wat?

r9 280x too?

may i know what mobo are u using?

ya sapphire r9 280x vapor-x

haihz... new problem

i got a
cooler master 500w psu 80+ silver
lga 775 core 2
4gb ram
usb- bamt 1.3

like cannot supply enough power.... i tot the card rated 250w + mobo (200w) = 450w
should be sufficient. it keep random reboot. then swap a 1250w ...run stable.

lol, r9 280x requires at least 350 @ full load.. if im not wrong la..

i have no idea why after after a while, my gpu load is keep on decreasing.. slowly slowly from 99..98... after 20 mins of running, now is 91..

did you put 'High Performance' in your windows power plan instead of 'Balance' ?
