AMD R9 290/290X Overclockers Club - Page 15

post #141 of 588
Wanted to see if it made any difference. I have heard to use both.
post #142 of 588
Hello again guys!

My 290X is still downclocking when i set the clockspeed above 1175MHz and + 56mV on the Core..
I have noticed that if i let the clockspeed stay at 1175MHz and push the Volt to +65mV it throtlles more than with the same clockspeed and only +56mV..
I have the Power Limit set to 150% both in After Burner 3.0.0 Beta 18 and CCC. The results are the same if i set the Power Limit to 125% also..

Im feeling that this isn't a huge problem, but i would really like to get the last 50MHz on the core to work all the time smile.gif
I have gotten my Core to 1225MHz without artifacts, but it keept throttling down halv the time..
It is free performance and since i have a Waterblock on it, i would like to get the most out of it wink.gif

In the beginning i was thinking it was because of the Silent and Uber-mode or something, but i have tried both, and the problem is still there.
Temp is not an issue because im allways under 42C on Core and Never above 46C on the VRM1 and 2 smile.gif

The next thing i thought of was to do a BIOS Flash on the 290X, but im not willing to do that unless i know for sure that it is the original BIOS on the Referance 290X card that is the problem..

Any of you guys got a fix for this?

BTW, my Memory Clock has been stable up to about 1550MHz with +20Mv on the Memory Voltage biggrin.gif

Try using trixx instead of AB and set your clocks that way. Afterburner would usually make the cards ramp up to your desired clocks while trixx will keep them constant

Really the best one to use is GPUTweak. None are perfect, but GPUTweak has the most options and seems to work the best.

If they are stuck to something you don't want, they will not come off w/o cracking into pieces. No bueno.

Good to know thanks! Too late for me now though lol. thumb.gif

Hello everyone,

I have a XFX R9 290, overclocked using MSI afterburner Beta, I increase the Vcore to +100 and power limit to +50. I used GPUtool stability test for artifacts.

I was only able to get the GPU OC @ 1115 (stable) anything over and I get artifacts, however the GPU temp does go up to 90c. My PC is in the basement, so the ambient air is fairly cool. (no throttling)

I noticed I can OC the memory all the way up to 1625Mhz with no artifacts in GPU tool. However when running 3dMark11, I actually get a lower score with ANY type of memory Overclock over the stock value of 1250.

Any suggestions to get the GPU OC higher? and what the heck is going on with the memory OC causing lower score with 3dMark11 ????

Thanks! thumb.gif

If you use trixx you can bump the voltage up by 200 mV which can help with the clocks. Also try them one by one I.e. Leave memory at stock and then push the core to its max then try memory. I don't really know why you would be getting lower 3dmark scores unless the card is throttling a lot.

Hello I had OCed my GPU stabil with no throttling with Catalyst 13.12, by ASUS GPU tweak. Clocks are 1160/1625 Mhz, 1.375V, 125%
Now I installed that crappy Catalyst 14.2 and the card is still downclocking to 800/1625. Is here any solution? I tried AB but higher OC leads to higher downclock. Why is this causing by drivers? Any suggestions?
BTW: for a stock clock with no downclock or throttling i have around 10% less performance than with 13.12 Catalyst

I am also getting Core downclocking when I run tests like Heaven 4 and Valley. I have my 290 set to 1150 core and 1550 Mem, +100mv. It throttle in almost every scene except for a couple. It is a constant fluctuation. Temps never go above 75 degrees.

What is the solution to this? Old drivers?
