Some Overclocking Questions

Lazz45

I am currently overclocking my R9 290 and using Unigine valley as my stability tester, I have bumped up the clock to 1120, and i began to see weird artifacts as the scene played. Will bumping up the voltage help this and allow for a higher overclock? Will overclocking the memory help?

 

thank you ahead of time

Bumping up the voltage could very well help you. Bump it up a little, re-test, and see if you see any improvements. Overclocking memory can certainly improve FPS and you will definitely see it when using high amounts of AA or at higher resolutions.

how much of a bump per run, 1mv? because when i unlocked it it started at +13

What temperatures are you currently seeing?

r9 290 tri-x with fans maxing at 50, i see max temps gaming at like 70 ish

Try bumping the voltage up by another 10mV.

okay will do, brb

 

Edit: still getting flashing grey diamonds on screen, I decided to just crank it up to +50 and received significantly less artifacting. i will increase more

Be careful of voltage increase though. Watch your temperature. How did you get to your overclock? Did you just jump to it or work your way there?

started at 1000Mhz, went for 1100 and was stable, went to 1120 and had a single stutter but nothing bad, jumped to 1150 looking for the instant crash but get artifacting, and with the increase i have gotten much less and I am slowly backing the clock back down. I am currently at 1142

You can't just brute force overclocking, sometimes too much voltage can cause you issues just as much as too little, heat also causes you issues that's why watercooling can net you more mhz.

well after playing with it some more, I am up to 1130 core, and 1425 (still oc'ing memory) and it is not stuttering anymore and is capping at 61 degrees during benchmark runs on valley, i will soon try out games

You need to let valley loop several times then benchmark it. Valleey doesn't like the AMD chips for that bench as my score is extremely poor considering my OC and I found out it was due to the fact Valley only uses one core for the entire program. On scene 6 my GPU usage drops from 99 to 70%...

I actually was wondering why i get that drop as well, I assumed the scene just wasn't demanding enough

CPU limit on a GPU bench aka poor coding job that didn't allocate at the least 1 more additional core for the program.

just ran valley for 15 minutes, then benched and capped at 67 degrees and memory up to 1450

Valley loves memory overclocks and it will benefit you in gaming, see how far you can push your memory speed first then push your core clock.

Will the core keep benefiting from increased memory?

Couldn't say sorry, I just know that I used to OC the core only but I get better results with a high memory clock and core clock combined.

okay so i am running the metro benchmark now, and i get a random flash of an artifact here or there (like 1-3 per run) is this bad?

 

Edit: its not so much an artifact but more of weird tessellation

Your images should be crisp and clear, you shouldn't be able to see anything in the form of artifacts no matter the colour, if you do then you're not stable.

bumped down the core clock, but the only thing i notice is that the smoke in the benchmark seems to have a pink hue

If your memory OC is too high and adding voltage doesn't help it will glitch just like core overclocking.
