Graphics card artifacts

[it24]

I am oc'ing my r9 290, and I am looking for artifacts while testing, and I was just wondering, what do they usually look like? Do I need to pay attention to see them, or are they very obvious?

 

Thanks

They are actually pretty obvious, but I've never seen them either, so don't quote me.

You'd notice.

Shadows flickering, textures moving, warping.

 

COLOURS and shit...

Google image search for GPU artifacts - https://www.google.com.au/search?q=gpu+artifacts&client=firefox-a&hs=RQq&rls=org.mozilla:en-US:official&channel=sb&source=lnms&tbm=isch&sa=X&ei=1hLlU-O9LJbj8AW244DQAw&ved=0CAgQ_AUoAQ&biw=1920&bih=920

Windows Boot screens can also do this type of stuff if the GPU is proper F'd.

 

When it starts, it usually builds, so it will start small or hit instantly. Either way,... you kill the program or restart PC, back off the clocks and your done

 

Do you even NEED the power by the way?

290 and allz.....

Every gpu kind of shows them differently but they are flickers of blocks in all kinds of flashing colours or black around the 3D image. If its more serious, then the whole image will be colour distorted and flickering and the animation gets all jacked up, that's when its very obvious. But typically for near the limit OCs, you have to kind of observe all the image for the random blocks popping in

Plus getting an extra 12-18% from your card isn't worth the effort.

It's already too beast for most game engines as it is.

I know you have triple screens, but you'd be better with another 290 for extra performance, your overclock isn't gunna add stuff all to triple screen FPS numbers.

Maybe an extra 5fps @ 1080p, but I doubt you'd notice the triple screen difference.

Yes, I do plan on getting a second 290, and I know the oc wont really help me, but I was just kind of curious about how far my card could go.   Also with how my gfx settings are on bf4 I just need a few more fps to be a solid 60

Yep Yep, As for BF4, know what you mean.

If you can get 1100Mhz without any extra core voltage than thats good. if you can get past 1200Mhz with voltage additions thats very good.

I keep mine (depending how hot the days are) about 1100-1150mhz and I leave the memory clock alone as it provides almost zero benefit as it's not being taxed anyway @ stock (unless benchmarks)

Aiming for under 75*c and I'm at 72*c tops, pretty happy, let us know what you end up getting

When you say with out any more core voltage are you talking about the power limit? Oh, and I wish i could keep mine that cool, I can in the winter, but god the summers are hot lol

Power limit makes sure that the cards stay at their intended clocks.

If you set 1000Mhz but -20 Power limit it may declock to save power, at your request, if you set +20, if will try harder to stay @ the 1000mhz.

Google AMD Powertune for 290x and you'll read about it.

Different from Core Voltage power (V-Core) which you can add separate. Vcore is predetermined by AMD to a clock speed profile.

 

The Vcore may need to be increased once your overclocks are hitting the limit for the voltage thats set (Causing artifacts in cases, so you add small amounts voltage to keep her provided with stable power to do so)

The voltage needed for 1000mhz is there, your pushing 1100mhz, you may need to slightly increase the voltage.

Generalizing of course, you NEED to read guides, and not just one, but a few. Specific to your model and you'll get a good idea from a few different reviews what it's capable of.

 

yeah summers I have to use stock clocks, hitting 81*c GPU temps, winter = 72*c MAX. Much better

Thanks! I doubt I will be changing the core voltage, so ill see what i can get with the stock.

[SkilledRebuilds]

Mine came stock @ 1140, dunno if that means my default Vcore is more than default 290's.

If so, yay I guess, if not, then I'd say you easily can do 1050mhz constantly if ours follow the default vcore without extra + normal overclocking procedures.

Mine came stock at 977, and i am currently stable at 1070 without artifacts so far, going to keep testing at 1070 for a bit. Will let you know where i get to

Sweet.

Oh typo. Mine came stock @ 1040, not 1140, I wish.

[SkilledRebuilds]

Here is something for ya to have a look at.

Comparing 290 @ 1200/1600 against 290x and such..

Metro:LL (290-OC Beats a Titan Black)

This channel (B4BG) has a lot of 290 @ 1200mhz stuff, so comparisons are easy done.

[it24]

Sweet.

I assumed it was a typo... That would be cool though...

So I got my 290 up to 1100mhz with no voltage change (from 977). I think I am going to keep it there. Don't really feel comfortable going past. Thanks for the help!

Good to hear, 1100Mhz is a nice sweet spot OC, esp without voltage.
