Hey guys, just wondering if I should get the Tri-X or the Vapor-X. Also, 290 or 290X? Sapphire seems to have the best lot of 290/290Xs.

At the current prices I would go with the 290 Vapor X and hopefully they fixed the possible black screen problem some 290/x owners
are getting on previous models.At the current prices I would go with the 290 Vapor X and hopefully they fixed the possible black screen problem some 290/x owners
Maybe I should have jumped on board the 290 Tri-X when it was 360 last week.
Well then, the moment the 290 Vapor-X gets <430, I'm jumping the gun. Hope it gets a nice 10% discount.
Ebay reference R9 290 or R9 290x + Corsair HG10 A1 + Closed Loop Cooler is now the best option for someone buying soon.

Wow that Corsair mod is damn fine and sexy. I love the idea of reusing that blower which has temp regulation for RPM directly from the card, and that plate with airflow on it will be great for VRMs.
Still think they can do it for $29.99 though, its just a metal plate mount and they are reusing the reference blower fan.
$29.99 + a 120mm AIO for around $35-40 would make for an uber water setup for cheap.
Unless they patented it someone else could get a factory to machine some as a competitor
. (Perhaps the same factory in China )

The power management on my 290 is the most advanced dynamic power delivery system on GPUs I've seen. Its behavior looks even better than Intel's Turboboost stuff.
What they failed was target power envelope and cooling. On the other hand, the (new?) Powertune looks extremely potent.
Yup, Hawaii has excellent dynamic power management. In some of my games where the GPU isn't loaded >90%, it actually downclocks on the fly to save power. Playing World of Tanks or Diablo 3, its at ~700mhz core only. Load up a stressful game and it stays at 947mhz. Importantly, in non stress games, when the scene becomes stressful, it boosts higher.
Fastx,
This was what I've read about the uEFI on the motherboards. Took a while to dig it up as most search results shown to state it didn't have it in the link. Finally found one that had the info.
Not sure if the wake from sleep issue could or could not be related or not.
How is your rig set up? uEFI boot? MBR or GPT? How are you hooked up to your monitor?
I'm uEFI, GPT, HDMI without issues so far....Knocks on wood.

So I went back over the black screen thread (every page) at OC I posted earlier. I found two Tri-X 290x owners (page 53&74) who had the black screen problem. I also found another 290 owner who flashed to the Asus PT 1 BIOS (page 91) and still had the black screen problem. So going to one of those two 290x BIOS is not looking as a for sure fix imo. Looking at both BIOS #'s per our GPU z I believe they are the same BIOS and the numbers in parenthesis I believe is just for the location. Also keep in mind we both are UEFI and using the same BIOS and I am having the problem on wake your and not. I seen a lot of guys running a R9 290 on the Asrock Extreme 4 MB so not seeing any problem there per MB or UEFI.
So after giving this some more thought I decided to send mine back to NG for an exchange and hopefully the second one will not black screen and I really think chances are low I will get second one with this problem imo. This problem seems to be a hard to one fix if you have it and I can't even find a for sure fix from research anywhere.
Ken thanks for your info/research in trying to help out, I appreciate it!

NG= newegg?
Maybe a rma would solve the issue? Only way to find out I guess would be to try.
If you were down the street and around the corner I'd try swapping cards to see if the issue moves with the card.
You show a dual bios in your sig. Does the issue happen on both win7 and win8?
Trying the switch in the other position wouldn't hurt. I've read many times that they are not the same bios. One is stated as uEFI and the other as legacy.
I'm thinking your cpu is overclocked. If so did you mess around in the uEFI with any of the power saving features?
Your sig shows a multi card reader. Is it connected to the MB usb header? If so have you tried unplugging it as some usb devices can cause the issue....Going by past cures for the black screen of death as I call it.
Did you do any special tweaks to save SSD space? Disabled page file? Etc.
Found another cure for somebody else's black screen of death.

Yes Newegg.
That would have been very cool of you and interesting!
No I recently put the Samsung 830 with W7 in my laptop temporarily. The WD 1TB is just a storage drive with no OS on it.
I on 1312's now and waiting to see if it black screens on 13.12's and if does I plan on switching the BIOS switch to test out. I have not contacted NG yet on a rma exchange yet.
I have the CPU and GPU at stock clocks while trying to solve this problem, also MB BIOS is set to default settings for trying to solve this problem. Win 8.1 power options are set to balance setting
I am running a Roswell USB 3.0 reader to the 3.O header. No I have not tried unplugging it but will keep that in mind.
I have indexing and restore disabled.

I'm getting the black screen regularly when changing overclock settings with Afterburner or Trixx, and loading Steam seems to trigger the problem too.
I highly doubt this is a hardware problem. I'd make sure none of the overclocking utilities are running at startup and try the card for a while at stock settings. That's what I'll do if it continues.

I stopped using afterburner a couple of months ago as it seemed more flakey to me.
I use Trixx and have it set to auto start so it will apply my custom fan speed only.
The following quote I just dug up over at overclock.net in the black screen of death thread. I found it quoted on page 95 http://www.overclock.net/t/1441349/290-290x-black-screen-poll
Originally Posted by Falkentyne
I explained this before.
This black screen from power transitions occurs because the memory clock jumps up to full speed (1250, etc), while the GPU voltage (which also controls the IMC--this is the problem) is STILL running at idle volts of 0.9xxx). That idle voltage is too low to handle the IMC, which is controlling the memory running at that speed (this is NOT due to defective memory modules btw), and thus the card black screens.
Another test you can do, to see (usually a few MHz beyond tho) where you will black screen, is to either run the refresh rate at 144 hz (only possible on 144 hz monitors) or find a way to LOCK the memory (and ONLY the memory) at the full 3D speeds, WITHOUT having the core running at 1000 or 947 MHz or whatever the default 3D speeds are) with the idle voltage at 0.9xx. If you can manage that, you should see massively flickering lines on the desktop, without black screening, since you will already be at a high power memory clock, instead of transitioning from 150 MHz to it.
The fix, as you found out, is to increase the GPU voltage, which ALSO increases the idle voltage to the IMC as well. (previous generation cards used separate voltages for idle clocks and 3D). This Is purely a bios/design problem. The IMC should NEVER be running at 0.9xx when the memory jumps to full speed, or, alternatively, there should be 'lesser' memory speed jumps, for when a light load is put on the GPU, so the memory doesn't jump from 150 MHz to 1250, but instead it could be 500 MHz for a very light load (like when the core goes from 300 to 450 MHz), etc.
What he stated does make sense to me. I was able to produce the black screen of death easily. Starting with stock settings I just upped the memory to 1475 and applied it. Looked fine until I scrolled up and down the page a couple of times.
I was having similar issues with my R9 290s. Issue went away with 14.6 beta drivers but mining speed was slow so I went back to 13.11 beta 9.5.
I fixed it in Afterburner by modifying the cfg file to use Overclocking mode 3. That set constant clocks for core/mem and this prevented the memory from downclocking even at idle which is fine in my case because the cards are constantly mining.
Without doing this, I got black screens, flickering lines on desktop, and crashes.

This makes perfect sense to me. It clearly seemed like an issue where the card was transitioning between states incorrectly. That's why I knew from the start that it wasn't a hardware problem (well, not one that an RMA would fix).
So, just to be clear, are you setting a higher default voltage to cure the problem? If so, how high is it? +25, +50, +100, etc.?
I actually have no problem with my TriX. I only get the black screen of death trying crazy overclocks.
You haven't run into the issue at stock speeds have you?
I'm kind of wondering if it's ASIC quality related. The higher the ASIC the lower the default vddc....According to gpu-z anyways.
My ASIC score is 81.6 with a idle VDDC of 0.977
What's yours?
Fastx has a higher ASIC score than mine. Maybe lower default VDDC? Guess he'll chime in later and let us know.

ASIC is 81.7%, default VDDC is 0.984.
Your theory is a good one. Would explain why some people are having the issue and others are not.
I have not had a true blackscreen while sticking to default 1000/1300. But I had a driver crash/recovery, and that's when I decided to roll back to 14.4 rather than the 14.6 beta.
It always happens on the desktop, opening an app, scrolling, or when changing overclock settings. I'll just leave it at stock for now. Actually have Afterburner running for its onscreen monitor, and I haven't had a crash...yet.
I also have a theory to toss out there - perhaps it's best to use hotkeys to set an overclock, and to only do so in game, rather than prior to launching. That'll put the GPU under load and avoid a memory overclock without sufficient core voltage.

Our cards are almost identical twins....ASIC wise. I did typo my VDDC should be 0.977
Hotkeys would work I think. A person would have to try it out and see. I'd imagine results would be greater for anybody who isn't applying additional VDDC. Some people just like to push the core with stock volts and up the memory clocks.
I mostly run mine at stock speeds as I don't really play games too much. If I crave more power I just apply my saved overclock in Trixx which gives more VDDC anyways eliminating the risk of black screen of death.

My VDDC is 0.969, I also tired it with a +50mv (per previous post) which raised my VDDC at around 1.023 at idle and still received the black screen on monitor wake up. Maybe for some guys this will work but for it didn't and that was 14.6x drivers.
I never got a black screen per doing all the same things Termie mentions (or things mentioned in my previous post) on both 13.12 and 14.6 drivers. It seems we have two different problems for getting a black screen imo, the only time I get a black screen once in awhile is on wake up, the monitor stays black and show's the no signal message. I tried turning the monitor on and off per power button, keyboard commands are unresponsive and I have to hit the reset button and reboot the computer.

I actually gave you the wrong voltage number too. Mine is in fact 0.977 as well, making our cards virtual carbon copies.
Anyway, I hope this all helps other folks dealing with the black screens.

What about trying the following to see if it's more of a software conflict?
Search for msconfig and select diagnostic startup and apply then reboot. I just tried this and sleep is still fully functional on my rig. It disables stuff that isn't needed.
Worth a shot to see at least.

I'm the same MTDEW from the overclock.net thread.
My ASIC is 67.2% and my default idle VDDC was 0.961V on the stock Sapphire 290 bios.
So i don't know if the ASIC quality has any bearing on the idle VDDC voltage.
Once I flashed it to a different bios the idle VDDC is now the same as you guys 0.977, and that eliminated my black screens.
And yeah, it looks like Fastx has an entirely different problem.

Just an update.
Looks like I spoke too soon on no problems, I just got my first black screen!
I went the opposite way, from 290-->770. You got a smoking deal and if building new I would have jumped on it over a 770, but I wouldn't trade that way. You obviously are a more advanced OC/OV consumer, and Hawaii is already a heat and power hog at stock. Coming from the MSI 770 where you don't have to run 80%+ fan to get a nice OC must be semi drastic in that regard.

That day I didn't have the ac on and room temps were warm but I was a little surprised myself when I seen what the max fan percentage that day was on GPUz. For another reference point check spinejams (post#33) Tri X 290 1200/1600 gaming max temps/percentage incase you missed it.
