1.Update motherboard BIOS
2.Try to install your RX in second PCIe slot
4.Try to reconnect (or change) GPU power cord or try another PSU. Any adapters (6pin to 8 pin or molex to 8 pin)?
5.Reinsall OS or perform win10 FULL reset
6.Try your GPU on another PC
7.Check your CPU and motherboard temperatures during games( Assassin's Creed III, Far Cry Primal, Dragon Age Origins, Overwatch and Battlefield 3)
8.Run HWinfo64>sensors only>Logging start and play for 15-20 min. I want to see that log
9.If none of those steps will help,then RMA your GPU-it is faulty
Good evening Redfury,
Thanks a lot for your feedback.
So, if I went through your list :
1. I updated motherboard BIOS to it's last version. Nothing changed (Far Cry Primal ingame Benchmark is my reference). When I say "Nothing changed", I mean benchmark is exactly the same as shown in the YouTube video.
2. I tried the other PCIe slot two days ago. Nothing changed.
3. I cleaned my system in safe mode with DDU, installed v16.11.5 driver. Nothing changed. I cleaned again and reinstalled v17.1.1 driver. Nothing changed.
4. I tried another 6+2pin power cord. Nothing changed. (I only have two 6+2pin adaptaters)
5. I reinstalled a cleaned version of W10 last weekend and nothing changed.
6. I don't have another PC, I can't do this.
7. and 8. I recorded two logs file for data analysis :
- hw64_logs_v16_11_5_crash_after_5_min_overwatch.csv : Before the re installation of v17.1.1 driver, I tried Overwatch and game crashed after 5 minutes. I got the error "Your rendering device has been lost". So I remove the v16.11.5 driver and installed v17.1.1.
- hw64_logs_v17_1_1_two_black_screens_overwatch.csv : After the v17.1.1 installation, I played Overwatch 12 minutes and I got two black screens (see picture below) during this period. This is the first time this bug happens to me. I don't know where this is coming from.
I hope these new information will help you to understand my problem.
Thanks again for your help.
1.Check your RAM. It reports abnormal frequency (200MHz???) Use CPU-Z,AIDA64 and HWinfo64(main screen) to check your real RAM frequency
2.Test your RAM by memtest 5.1(CD) for 30-45 min
3.+12V voltage is quite bad. You need another HQ PSU
Hello again redfury,
Thanks for your answer.
1. I think my RAM is OK. Frequency is the following one, as you can see :
2. I ran MemTest for more than an hour and got the following result :
3. You made me doubt about my PSU. I bought a Corsair for its performances. And Corsair announced 85% efficiency, for 650W, it should be 552W delivered, right ?
I think this should be enough for a RX480 and a Phenom II X4 BE 965. But, when I stress-test the GPU, +12V goes to 11,6V. And if I only stress-test RAM and/or CPU, +12V goes to 11,8V.
Nevertheless, the RX480 should work fine with 11,6V, no ?
I don't know what to do now. Thanks again for your quick and useful help.

11.54V- it is near critical value. Good PSU will not act like this.
RX 480 is very sensitive for voltage quality. It loads PCIe slot and power connector very intensively (especially 6 pin variation)
Thanks for your reply.
Ok so, if I understand well, I have two solutions :
- Replace my brand-new PSU for another one more powerful
- Return my RX480 and buy another GPU less sensitive to voltage quality
Are there the only two solutions you see ?
Maybe it's the motherboard which is not able to give enough power supply through its PCIe port ?
Your PSU may be powerful enough but it provides a bad voltage. It is two different things.
You must change something in your system or better to test your GPU on another PC.
Motherboard can be involved in your problems too, but it less likely.
On my opinion you have faulty PSU or GPU (maybe both)
Thanks a lot redfury for all of your answers.
I sent back my RX 480 to RMA and bought a GeForce GTX 1060 instead because power consumption is more optimized.
My computer works perfectly fine now, thanks again for your time and expertise.
listen redfury, the VS series is not the best; VS = Value Select
Many users in many forums, are not exactly thrilled.
