Hi All,


I recently bought this graphics card : XFX Radeon R9 390 "DD Black Edition" 8192MB GDDR5 PCI-Express Graphics Card (R9-390P-8DB6) To replace my old Radeon HD770.

I bought this bundle from OverClockers in 2012 and has been working fine.

CPU: Intel Core i5 3570K 3.40GHz Ivybridge CPU
Motherboard: Gigabyte Z77-D3H Intel Z77 (Socket 1155) DDR3 Motherboard
RAM: Samsung Green 8GB (2x4GB) DDR3 PC3-12800C11 1600MHz Dual Channel
PSU: OcUK Crusade 750W Dual-Rail High Efficiency '80 Plus' Power Supply

I took out old Graphics card and put in the new, but had no signal input. After a few hours of reading and trying various things, I thought I would try updating the bios as a last resort.

I updated bios from F8 to latest version F23b, which went smoothly, new graphics card detected, shows display. Boots into windows. Have been playing games etc.

Anyway, have had machine up and running, was playing games for all day Saturday/Sunday with no issues.

Yesterday about an hour into gaming, suddenly the monitor start disconnecting and reconnecting about 3 or 4 times. Then black screen and "no input signal" message, but all the lights are on and fans spinning.


Tried reconnecting monitor leads, but nothing, so I rebooted PC... checked my event log, apart from an unexpected shutdown error nothing out of the ordinary.

Fired PC back up and log back into game. About 20 mins in same thing happened.

I Downloaded GPUID, started monitoring temps while playing, reached a Max temp 70c then about 10 mins later the monitors started disconnecting and reconnecting but this time the PC went off.

Tried to turn the PC back on, nothing, no lights, no fans. Graphics card was warm but not hot to touch. After about 5 / 10 mins the PC started, all lights on fans spinning, monitor displaying "no input signal", then it would reboot, display "Gigabyte BIOS UEIF" logo for about 10 seconds (blue screen and logo only, not like the normal BIOS) then reboot and loop.

I tried my old graphics card as I thought the new one may be causing problems, but still in same loop.

After several failed attempts of trying to clear CMOS by shorting the two pins, I held down power button and had a message that old bios was corrupt and restored old Bios back to F8 which got me back into windows.

I have downloaded a fresh copy and have flashed the Bios to F23b again, as the new graphics card will not work under the F8 Bios.

Am I missing some settings in the bios as they are all set to default values ? Or something else ?

Cheers for any help.
 
I would replace your power supply. The OcUK Crusade is I believe a very cheap brand of PSU which OcUK no longer sell. I expect you are overloading it with the R9 390.

If it could actually deliver 750W reliably you would be fine! But I somehow doubt it can. :(

It does sound like it is overloading the PSU and throttling then cutting out. Doing this repeatedly could easily damage your PC.

I'd recommend this: https://www.overclockers.co.uk/ante...0w-80-plus-bronze-power-supply-ca-148-an.html

But see what others say first... :)

Can I just check, as you swapped card for card, that you ran a full DDU and then reinstalled drivers?

I had the same issue when I updated my sons 7XXX card for an MSI 390. Full DDU and driver reinstall fixed the problem and I felt a bit silly. Sure you have already tried this but mention just in case.

Edit - and he has a 650W PSU.

Good luck
 
Somehow in the process I accidentally corrupted my windows install lol, so I did a full format and reinstall lol. So I can defo rule out driver issue.

Good psu, but you should not really need 850w for your system tbh.

A good 650w should be optimal, but if you want a little head room, 750w would be better and still save you some cash. For example:

https://www.overclockers.co.uk/xfx-ts-750w-80-plus-gold-power-supply-black-ca-018-xf.html

I believe this is also a Seasonic made unit with xfx branding.

The Seasonic 850W the OP chose is an excellent PSU. The XFX I have is essentially the same one with a single 12V rail. I have overclocked 290X crossfire on this and it handles it perfectly. My complete system with the crossfire draws a maximum of 760W from the wall running Valley Benchmark @ 1440P according to a Kilowatt power meter I have plugged in all the time. In gaming the power draw is around 650W most of the time.

Although a 650W will be fine I think for future proofing and potential crossfire later on, a higher wattage PSU is money well spent.

I was just trying to save them some cash if possible as the current system will barely break 50% use and potentially be out of the efficiency range. Completely agree the 850 selected its a fantastic psu though and if hoping to dual card later theres no doubt it the best choice.
 
I've had a 390X running on a 500W corsair builder series 80+ bronze along with an overclocked phenom ii (125W tdp).

I'd be comfortable with a 550/600 watt psu for a single 390 with room for a bit of overclocking.

Quality over wattage always. A superflower golden green or similar would be good.
