The AMD R9 290 (non x) Thread

i have the same problem. I can oc it and it runs finbe, however if i leave the oc on and shut down and re boot my system i get a black screen. If i quickily disable overdrive in CCC it does not black screen on me.
I think it is to do with finding a stable OC more than anything...
anyone else have any other experience with it?
 
On the 290 I believe it does nothing. Obviously if you have a crap BIOS flash it gives a get-out clause, but in terms of performance it's totally benign.
 
Ive noticed with my 1060MHz overlcock on the core that the card throttles back during heaven benchmarking, even with the card in full leaf-blower mode and temps not going above 75 degrees?

How can I stop it from throttling?

Also, is screen tearing a sign that an overlcock is unstable?

what are the max volts you guys are putting through on the stock cooler? i have 1300 at the moment. i do not got over 94 in heaven. This gets me 1150 on the cc and just under 1400 on the mc
 
I'm using 1.250v which is its stock voltage, it actually gets a max of 1.227v in gpuz. I can get 1150 core 1300 mem.

I'm using the Asus 290 bios ATM I've gone to 1.275v and according to gpuz the card gets a max of 1.250v. This let's the core get to 1175, temps stay under 90c with my custom fan profile which never gets above 51% one of the vrm's hits 76c the other 56c.

I'm tempted to push the volts to 1.3 myself just see what my card can do it seems a good clocker so far its just I'm spending most time in games! At 1100/1300 the card runs bf4 in eyefinity with ultra settings no msaa high fxaa at 50-70fps in 64p mp games so going further seems pointless.

Hey,

Would you mind posting a screenshot of your custom fan profile please? I'm not liking mine much, and it would be nice to see what other people are doing.

Thanks :)

Try renaming the Heven.exe file to something else. AMD may be running profiles which restrict clocks for certain benchmarks base upon the executable.
 
Maybe you hit a power limit? 290(non X) probably use more power than 290X as they'll be (presumably) lower quality parts. It's like Piledriver 8320 v 8350, an 8320 will run at 8350 clocks easily but will in most cases use more power and demand more of the motherboard in doing so.

7950 was 100mhz or so at average lower clocking than a 7970.
still wont do much difference with fps overall tho.

I'm on my phone ATM but when I get back to the PC I will sort a screenshot out.

I don't know if any of this info is going to help any of you but after a good 4 days benching and oc'ing my 290 this is what I've learned,

If you flash to the Asus 290 bios, uninstall your amd drivers and then do a safe mode run of ddu uninstaller, then a clean install of your drivers after you've flashed the new bios

Don't touch amd overdrive.

Oc the voltage if you need/want to using GPU tweak but don't use it for the clock speeds, also don't leave the program running when gaming.

Oc the clock speeds using afterburner.

Save your best clock speeds to a profile DONT let afterburner apply them at startup.

The last point is the most important in my experience with the 290 if you let ab apply the clocks at startup the black screens show up in games if you apply the OC yourself at least for me this eliminates the black screens.

A custom fan profile helps these cards massively I wish vbe bios editor worked with them so I could save mine to the bios. A 50% fan speed which is almost identical to a 48% fan which you get at stock is a lot more efficient at cooling the cards and helps prevent throttling.

The elpida ram does seem to not like been over clocked but as of right now we cant control the memory voltage I've got a feeling it needs more volts to play nice.

Here is the custom fan profile I am using for stock and overclocked,
