Problems with R9 Nano

[twoodster]

Hey! Got my XFX R9 Nano this morning but the computer is shutting down pretty much instantly when I start games. Kernel-Power 41 errors. Any ideas? This is my spec:

CPU: Intel Core i5 4670K
CPU Cooler: Zalman CNPS5X Performa
Operating System: Windows 10 (64-bit)
Motherboard: Gigabyte Z87-HD3
RAM: 16GB Corsair 1600mhz Vengeance (2x8GB)
Hard Drive: 1TB S-ATAIII 6.0Gb/s
Case: Corsair Carbide 200R
PSU: 650W Corsair VS

I'm guessing power supply but I was under the impression 650W should be more than enough. Does a Nano require more juice than a 280X?

I would hazard a guess @ PSU issue
also, your asking a question with the answer already if the computer is giving a power error and your pc is shutting down when you put load on the graphics card = PSU

I'm only asking as its a new graphics card and it would be a bit of a coincidence if the power supply has suddenly failed when it was fine powering a 280x a couple of hours ago.

 

[twoodster]

As above, confirm your using an 8 pin PCI-E power connection to the card and that it's seated properly.

I'd then advise asking friends etc if they have a spare PSU you can borrow to test with.

Corsair PSU's have been terrible the last few years, since they changed OEM to use cheaper components etc.

What power connections did your 280X use? 8pin and 6pin?

Yep, 8 pin and 6 pin for the 280x. So just using the same 8 pin I used for the 280 with the Nano

 

[twoodster]

It's advertised as having a 6+2 pin PCI-E power connector, confirmed in the reviews also.

Yeah, sorry, it's a 6+2. Would that be a problem?

 

[twoodster]

A driver won't shut down a pc it will however bsod or restart the pc.. A full shut down is power issue.

It shuts down and then starts up again about 2 seconds later.

I've just tried swapping it into the other PCI Express slot but same problem. Reinstalled the drivers 3 times - same problem. Tried taking the soundcard out. No change.

Was really looking forward to a bit of American Truck Sim tonight too Ha ha

 

[twoodster]

Is there another PC you can test the card in?

Not anything capable of running games unfortunately

 

[twoodster]

Do you use a surge protector?
Disable hibernation and sleep modes in bios.
Turn off power saving.

I don't use a surge protector, no. Have turned off power saving etc - same problem.

Just put my 280x back in and it works fine, so I'm leaning towards a borked card given the Nano should use a fair bit less power than that

 

[twoodster]

Is your motherboard bios up to date as that can cause problems?

Thanks for the suggestion. Just updated that - same problem though unfortunately.

 

[twoodster]

i had a similar issue, was caused by RAM.
did you check event viewer?

I have done. Can only see Kernel-Power 41 errors

 

[twoodster]

It may be worth checking if there is a BIOS update for the motherboard

Yeah, I've updated that but hasnt made a difference unfortunately. I'm a bit lost for ideas now.

 

[twoodster]

Kernel-Power 41 error, all that means is windows has not shut down properly.

Can you start in safe mode?

I would say a dodgy card if your 280 works fine as that's 25 watts over the nano.

Yeah, I can start in safe mode ok. Windows and everything runs fine. Playing videos etc Its literally when I play a game that I run into problems. And it doesn't seem to have to be actually within the game engine either - it's quite happy to give up the ghost on menu screens too.

I'm not running any overclocks so BIOS is pretty standard.

 

[twoodster]

ok i did a quick search, some ppl with similar problem and with Gigabyte motherboards seem to solve this shutdown issue by deactivating Erp Mode in the Bios.
other seem to solve Kernel-Power 41 error by removing power saving options, and sleep mode on harddrive and such.

Thanks for looking! ERP seems to be disabled by default in the BIOS though. And power saving is already turned off.

 

[twoodster]

Have you tried changing the AMD drivers for older versions?

I seem to have to roll back to Crimson 15.11 to get my XFX nano to work on my GA-Z87X-UD4H without locking up.

Its been crunching happily for the last 24hr.

Oh really? Interesting. I'll give that a go now then. I'd only tried the latest drivers up until now.

 

[twoodster]

The gpu will draw more power when you play a 3D game hence why I suspect psu.
An old psu can have issues such as excess voltage rail ripple even if some things work fine. How old is it?

Errr, 3 years I think. If it was the power supply though I don't understand why my R9 280x would work fine - especially as it uses more power under load.

Tried the older drivers and the same problem anyway.

 

[twoodster]

If I did get a new power supply what would be recommended?

 

[twoodster]

Hi all! Firstly, thanks for all your thoughts/suggestions - much appreciated! Just to say that I ended up returning the card and they've confirmed that it was faulty. Replacement should arrive tomorrow so hopefully all will be ok

 

[twoodster]

New card. Same problem. I could cry right now haha

 

[twoodster]

Is this the Nano that's just been on offer?

Not the Powercolour one no, this is the XFX card. Although from what I understand all of them are the same anyway

 

[twoodster]

Have ordered a XFX TS 750W 80 Plus Gold power supply from OC just to give that a go. I've never had a problem with a dodgy graphics card before, so two in a row seems a bit unlikely.

 

[twoodster]

Yeah very odd that, i just can't see the PSU being the problem, as it powers a 280X fine, and they use more power, 650w is easily enough for a Nano, but getting 2x in a row doing the exact same thing, is well odd too.

Na, I'm by no means convinced its the PSU either but I just wanted to make sure before I sent it back again! It's all very odd. Always considered a graphics card a pretty stress free upgrade, but this is turning into a real ball ache

Edit: Thought it ran ok in Windows but now this has started happening. Disabling and re-enabling the graphics card in device manager fixes it.
