I did not see this posted anywhere.

Nvidia is not on topic in this thread, or this forum.

If true this could be awesome news! Just like the 290 => 290X unlocks and the 6950 => 6970 unlocks before that.

if it's true and with a high chance of success it would make the fury a lot more interesting, considering it's not that great for OC, but with unlocked shaders + OC this would be a very nice gain over stock.

Reading through the thread, it looks like you can do partial unlocks as well so even if you have bad clusters, you can still unlock some of the good ones and get a bit more performance. Still early on so if it were me, I'd wait to make sure there aren't any other kinks to work out, but looks good so far :thumbsup:

It certainly changes the value proposition if a good chunk of these can unlock. Mostly because it would be awesome to have a Fury X but on Sapphire's ridiculously quiet air cooler

EDIT: one user in there is reporting that the 56 -> 60 CU unlock (4 of 8 CUs) garners most of the performance improvement (3%) with the last 60 -> 64 unlock getting only another 1%.

I'm afraid to try it, but going from 3854 to 3840 Shaders sure sounds nice. I'll wait for more to take the plunge. My Fury can't even run at 1090MHz, so I don't think I won the silicon lottery (1080/550 was stable but I just keep it at stock 1040/500).

That's pretty neat...I would've expected AMD to take some more measures to protect from that kind of stuff to happen...but it's awesome for the consumer, if it can still be cooled/powered properly.

wait what?!? The cooler that's on Fury X is designed to cool 500w cooling isn't an issue at all with Fury X

But....they're talking about Fury (Fiji Pro) and not Fury X (Fiji XT). Furys' are mostly air cooled cards and a few different designs from different Vendors exist....that's why you need to be careful there and check if your version is even able to handle it properly.

watch the reviews - fury cards are some of the coolest running and quietest - these are the furies not X but you are right on that

Not really.

 

[crisium]

Not really.

So you recommend that it's not worth the risk? It should translate into 3-4% gains, which is not undesirable if it is truly free.

I'm sure you typo'd, unless disabling SP results in performance gains?

Tried this on my R9 200's, since the OCN thread lists them as possible candidates. No go. 4 of the disabled CU's on each card are disabled by hardware lock.

Oh yeah, that was a typo. It is patently obvious that I meant 3584, which is the Fury Shader amount (public knowledge). I guess his post was just making fun of me.

I went ahead and did this since I have dual bios anyway. 3840 shaders are working for now. GPUPI gave a predictable 7% improvement (which will likely translate to half that in game performance), so now to see if I don't artifact in games.

yeah all 4 on my R9 290 are also hardware locked

Ooh, time to check my 290s.

Edit: Nope, locked. Oh well.

 

[guskline]

My 290s are also locked. I can OC the vcore and memory.

 

[Hitman928]

From what I remember, there was a limited amount of 290s when they first launched that could unlock to a full 290x but then AMD started to hard lock them soon after.
