Do I need to RMA my new Sapphire Vega 56 Pulse?

Grabbed one of the Black Friday bargains from OCUK at £300 with the games bundle the other day. GPU Arrived Friday. I have an ageing system - it was set to replace an HD 6950! I will gradually upgrade the rest of the machine.

But I've been beset by problems. At first, I was getting a 5 beep error from my motherboard and the PC wouldn't boot. After a bit of perseverance, reseating the card, the RAM, tidying cables up etc. I managed to get it to boot, install all the drivers etc. Before I could test any games on it, I'm getting the 5 beep error again whenever I try and start it up. As I wasn't getting this with the old GPU, I am inclined to believe it is the card. But I also thought it could be insufficient power or my motherboard not providing enough via the PCI-E lane? I have a 600W CoolerMaster Gold rated PSU, so it should be ample, but I know these Vega cards are notoriously power hungry.

How straightforward is an RMA with OCUK? Card only arrived last Friday.

I'd appreciate any advice. Thanks.
 
Make sure you are using two separate PCIE power cables and not daisy chaining with one as these cards draw a lot of power. Make sure the cables are attached securely.
 
Make sure you're on the latest bios release as well (even if that's old in itself), it's a common problem for the system not to boot with older bioses.
 
Hi Itron,

Thanks for the advice, yes I have used two separate 6 to 8 pin cables from the PSU to GPU. Interestingly, my machine won't even power on now, so starting to wonder if the PSU, which is now 7 years old, might have given up the ghost.
 
BIOS beep codes are listed here. I'm guessing you don't have a Dell so it's not your CMOS battery.

Does your PC still work when you put the old GPU back in?
 
I'm truly stumped now. Bought a new 600W Corsair Gold PSU in the Amazon Warehouse sale which came same day. Hooked everything up. I can't even get a blue light from the power button anymore. I've built over 10 machines in my time, never come across anything like it. Now I can only think it's the MOBO that's completely gone.
 
Wow, what an absolute conundrum. Clearly, I'm dealing with more than one problem here. Completely took the whole build apart and did a full rebuild, including moving the RAM to different channels - with the new PSU. Managed to get power again but getting the same 5 beeps when new Vega 56 Pulse is connected. With the old GPU it will boot fine (pretty much, besides some weirdness with my keyboard lighting and occasionally needing to be put in a different USB socket). It works with the old PSU as well. I can only surmise that either the Motherboard is having power delivery issues, or the Vega 56 was DOA...or quite possibly both. I have no way of knowing which it is though, besides RMAing the Vega or buying a new motherboard...the latter not really possible just yet - want to wait for the latest Ryzen 2 CPUs to drop next year to make that move.

Its an old one tbf...MSI h67ma-e45, old socket 1155 paired with an i5 2400, both circa 2011.

If it doesn't have a UEFI bios it won't work with modern cards like the Vega 56. Can you check the motherboard page and see do they have any Bios updates?

Actually looked up the board, it seems to have a UEFI BIOS. If you haven't updated it to the latest, it's still worth trying. I still think that's your problem, not the GPU.

I agree, there's a BIOS update from 2013 which actually says as one of the improvements "Enhanced PCI-E display card performance." Infuriatingly, I don't have a USB stick lying around - several seem to have gone AWOL. Away for a week now so it will have to wait.
