Re: New AMD GPU


[re: epyon] [link to this post]
 
Well pcper have done an investigation now, they claim the 960 gtx is actually nowhere near the same issue.

There is also reports of broken motherboards by some people (low end boards).

The issue I see it is AMD tried to pull a fast one on the power draw claims by under supplying the external power from psu, if the card is not overclocked and not overly stressed e.g. 1080p tomb raider then it goes slightly over power draw spec which is dodgy, if the card is overclocked and especially if stressed heavily then things go a bit crazy. pcper have promised now to run some tests on low end boards to see if the boards die. High end boards are ok because they over engineered, they like allow more power through the traces than the spec requires expecting spikes from users overclocking cards and so forth. So I have changed my view a bit now.

It probably will be fine on aftermarket cards as they will have 8 pin instead of 6 pin or a 2nd 6 pin and adjusted bios to reduce the pci-e slot power draw. The drivers that amd says will fix this I expect will undervolt the cards and cap clock speeds.

In reply to a post by epyon:
I've got one

its running fine on my old mobo from 2011 with a 2500k

i think its a none issue tbh

since 1000's have been sold which only 2 people have reported this issue ?
I agree.

As with everything, ten or twenty YouTube commentators get hold of it and it becomes big news. In reality it could be a very tiny percentage of cards that end up having an issue.

Conversely of course, it could indeed be inherent to "the design".

It's far too early to tell properly.

Well this is interesting, undervolting the card makes it more stable allowing a very slight performance boost!

yep that will happen when the card is bottlenecking at power limits.

Yes i've just flashed mine to 8GB

though it seems random, Some have 4GB and some have 4GB flashed on a 8GB card

I bought a RX480 4GB for £213 to upgrade from my old HD6950.

EDIT: There is some rumours of the RX470 flashing to a 480 as they're not lazer cut dies.

I think no issues will be found, if it went the other way he would have released fast for the drama.
