AMD R9 290/290X Overclockers Club - Page 16

post #151 of 588
Got mine at 1075/1350MHz for daily on the stock cooler (with +13% voltage, and +10% limit)

Maybe raising the limit more will improve performance? Either way waiting on a waterblock to see how well it clocks.

Owning a Gigabyte 290x WF OC and has developed a very unusual problem: the card works fine in 3D without any artifacts at all, no matter how much I keep it inside a stress-testing application as Heaven. As soon as I quit the application, I get horizontal corruption lines on the desktop and sometimes the driver resets after that. Can this be fixed? What I have tried so far:

-all drivers from 13.12, all behave the same
-testing the card in two completely different setups which also means different power supplies, one 850W and one 1.1KW
-disabling ULPS and setting a constant voltage via Sapphire TRiXX
-Flashing an ASUS BIOS with lower GPU clocks by hoping for more relaxed timings for the memory too
-Switching between the quiet and uber BIOS

Thanks in advance!

I'll have my Sapphire R9 290 Tri-X arriving tomorrow. Can't wait to install it and break out all the games I've been wanting to play in 1440p, high settings without much/any lag biggrin.gif

Usually means the memory is clocked too high, and when the card goes to 2D voltages you get those lines. Bumping the core voltage usually helps, or reducing the memory clocks.

Raising AUX VDDC helps as well against this. My Tri-X 290X does this as well with stock AUX VDDC at 1625Mhz VRAM. But with +100mV AUX (No idea if +100mV is even safe but k, we'll see) there's no corruption at all.

AUX isn't directly related to memory voltage but still.. if it helps it helps biggrin.gif

Btw, my cards a Sapphire Tri-X OC 290X with Hynix VRAM @ 1150/1625 +100mV 24/7. No arti's at all.
Voltage won't scale past here as at +200mV it only reaches 1180Mhz core without arti's. At 1200Mhz there's noticable ''white checkerboards'' in tree textures for example in BF4. Plus, +200mV for the Tri-X cooler is a tad too much as core stays at ~75c on 100% but VRM1 hits 95c under long loads.

I ordered a ColdZero backplate to go wth the beast and i'll post pics once I got it in smile.gif

My card is not overclocked at all and does this at 1250MHz RAM clock. Guess then one of the RAM chips is shot.
post #157 of 588
Guys, does anyone know what could cause the following issue:
My new sapphire tri-x 290x just stopped dropping clocks in idle mode (win only) as well as in 3d, the clocks remain 1040/1300 Mhz no matter what (as per GPU-Z the CPU usage is 0%). The temps is high because of that as well as power consumption is at full mode while on windows. Catalyst driver reinstall does not help.
Card is not overclocked, sapphire trixx software removed.
Please advice! I have no clue what's going on with my system.

Hi,

I plan to crossfire 2 sapphire tri x r9 290.

Can a TX850 PSU support a 3820 + the cards?

Thank you,
Flame Princess

Whoah, I forgot about this thread tongue.gif My PowerColor PCS+ 290X replacements should come in sometime next week, so I'll finally be able to spend some time with them (they were performing worse than a 290 clock for clock).

OrangePhantom, 850 is plenty as long as you keep them from eating up too many volts. I believe the TDP is around 300W per card, and if you throw some volts on it, expect that number to jump to around 400W. I believe that +100mV increases power consumption by around 100W, to put things into perspective.

Just because the tdp is 300 doesn't mean it will run at that. Take it for what you will, but gpuz has never shown my card pull over around 320 and that was with pt3 bios and 1.4V
