i think the difference between the 290 and 390 is 100MHz. if you can oc your gpu 100 or higher, then i suggest you do that instead. Flashing a different bios has risks such as blackscreens.

not quite.


I realized I can benchmark at 1080P (my screen resolution) @ 1200/1600 137mv without artifacts or blackscreens.
But then I realized my card blackscreens instantly if I try to game at 3k or 4k resolution with these clocks.

So, I decreased my memory clocks until it stopped blackscreening at 4K, but it never stopped blackscreening.
So, I decreased my GPU clocks until it stopped blackscreening at 4K, but it kept blackscreening.
That's when I realized my card will blackscreen at 4K if I use more than ~110mv on the core. Bummer.

So, I fixed the vcore at 100mv and reached 1200mhz on the GPU Stable at 4K
Next, I tried to overclock the memory but I found I could only reach 1350mhz stable at 4K.

No blackscreens.


For added stability, I game at 1190/1345. No Issues the entire weekend.
Any idea what is causing this ?
Blackscreening depending on voltage + resolution ? hmmmmm

I had the same issue with my old card and I was confused why it was happening. Happened only while running displayport...

ok. I found out a very important thing. The blackscreening is related to powertarget. If its 0% no blackscreening. If I set it to 10% or anything else than 0%, blackscreening appears.
Any ideas ?

Out of the 3 different cards I owned at one point, black screening at say idle occurs due to not enough GPU voltage for the RAM clock set.

If I lowered RAM clock without touching GPU voltage it solves it.

If I don't adjust RAM clock but up GPU voltage solves it.

Only my experience with the cards I had, may help but don't know as all cards can differ how they react to a change smile.gif .

For me it is the same. Memory is very sensitive to GPU voltage, even in idle.

It allowed me to get to 1260 mhz without blackscreen instead of 1240 mhz and occasionally blackscreens. The result you may ask? http://www.3dmark.com/fs/6192783. Let me know if they work. I may do some more tinkering.
I've made two bioses, one for elpida and one for hynix, they use the stilt's timings. I can do a version with stock 290 timings also if anyone wants it. (my personal bios uses tight stock 290 timings)
Anyways feel free to try them and please comment about your experience with this bios smile.gif (if they work tongue.gif).

Hey fyz, tried your bios (the elpida one) on my r9 290 reference card, and i´m getting blackscreens and driver crashing constantly now frown.gif. I didn´t have these problems with the modded bios insanityone made, and i used to use the memorymod version of his bios. Not sure what´s the problem, but upping the core voltage and power limit seems to help, and it stops the driver from crashing tongue.gif. Any ideas?

Otherwise the bios seems to be good, and stable when gaming smile.gif

The aux and core voltage is higher in Insan1tyOne's bios. Increasing the core voltage is easy, if you want to try that.

Hi all. i have powercolor r9 290x and using 1.7 290x stock with these settings


i want to use always stay my gpu and memory clock at 1075- 1250mhz how can i do that?change gpu1 gpu 2 and gpu 3 clock same as 1075- 1250 mhz and dpm7 voltage 1238 enough or change have to all dpm settings?and how can i change device id for full 390x? Sory for my english. i hope i can explained

I´m now using afterburner to increase the core voltage but my gpu drivers always crash at the startup. doh.gif Could you please provide me a version of your bios with the same aux and core voltage that the Insan1tyOne's bios has? I would do it by myself if i could but i really don´t know how, and i didn´t find any proper tutorials etc for this. tonguesmiley.gif Could you please make one? That would make my day. Thanks. smile.gif

I could make it real quick, but i don't have so much time, but I will make one for you. You just have to wait sorry.
