R9 290 screen flickering at 1120MHz, how to fix it?

post #1 of 6
Thread Starter 
Hello!

when i overclock my refrence R9 290 to 1100mhz its tottaly fine, but anything over that will couse litle flickering in the scree, like white horizontal lines flashing every where, its increase when i go to 1150 or 1200mhz.
is it something can be fixed? taking into consideration no matter how much do i increase or decrease the voltage its wont affect the flickering, nether do the temps affect any of this.
if its not a voltage related problem or temps related, then whats the problem exactly? am using 13.12 driver.
things i will check and update:

CPU performance (incase its bottle neck my 3x290)
RAM, will also check if its throttling it
will post a screen shot if any of these 2 do reach 100% even for a split of a second
do you recommend any software other than using task manager to check the load on these?

thanks in advance

Can you list your full system specs? Also, it is possible that 1100mhz is the wall for your card. My two 290x will do 1150 w/ +100mv but even at +200mV they will not do 1175 without driver crashes and artifacts

the driver do not crash at all, its can work at these clocks for days but with flickering, anyways, here is my system

i5 3570k
Gigabyte OC force
8 GB RAM from Gskill
1250W gold seasonic PSU
windows 7 64 bit
3x MSI R9 290 reference

Try each card separately.

One (two?) lesser cards in Tri-Fire is likely your issue -- all it takes is one card to limit you ..... like the weakest link of a chain. Also 1250W running 3X the 290 while OC is likely on edge of your PS limit.

When you OC these cards they really eat power.

If this happens in 2D and If youre overclocking your memory, you may also need to increase core voltage (youre gpu might be able to run at stock volts but something about the memory controller getting its value from gpu voltage)

For instance if i downclock my core to 900mhz, but increase my memory to 1500mhz - i HAVE to increase gpu core to 1280mv for it to run without wierdness in 2D mode (once i run a game, then everythings fine at stock)
