Well I tried to OC my tri-x r9 290 only to get the black screen that everyone talked about. So I can't OC my card. I really don't care since I feel the card is plenty fast enough for my needs. The card is fine if I don't OC. Well if anyone has any ideas on what could be wrong you can post if ya want to but this not a really big deal to me any way. I am using the 14.8 drivers. And I used After Burner.
Increase voltage to +100mv and start from there. Black screens are memory problems, memory voltage scales with core voltage.
It is a risk overclocking cards.Maybe 100mV is ok to start with. Owned 4 R9 290/X and they all did 1200/1600 with Sapphire Trixx. 100mV was not enough in afterburner.Just saying that's all.
Seems Sapphire have released a BIOS update for the 290/X which could solve blackscreen problems..... https://www.sapphireforum.com/showthread.php?33437-R9-290-Black-Screen-Fix!!! From what I can tell it looks like they just bumped up the voltage by 25mv, basically the same solution as what Mac said. Sapphire won't make the BIOS public or allow any links on their forum, only way to get is through a support ticket. Someone supposedly uploaded the file to TPU but I checked and it's not there.
My Vapor-X is +25mv out of the box, which i probably why no one with vapor-x is having black screens.
Sold off the last of my 290 cards today.But what I was running Sapphire Trixx today at for benches before selling. GPU Clock:1175 Memory Clock: 1600 VDDC Offset: +150 Power :+50 This may also help you out below Copy and paste from Jan 2014,Tempetures got much better over time but were still good back then. I ran a few Valley Benchmarks 1.0 at 1920x1080 8xMSAA ExtremeHD Preset Level, all runs 20 minutes to 30 minute runs.

^ I get basically the exact same results with my Tri-X. 1200 core requires about the max +200mV offset (and even still FurMark gives artifacts). Good to know my findings are in accordance with yours.
The Sapphire Tri-x card is great card and also he is referring to this data base on TPU http://www.techpowerup.com/vgabios/
I tried to post the new Bioses but it says they were already uploaded? Guess you could check TPU for them now :/
I had the same problem when i tried to upload my newer Vapor-X Bios. I gave up. I think it doesnt check the model, just the actual version string. So if someone uploaded the same bios version, and incorrcetly put it in a different model, you are SOL and good luck finding it. lol
