So, this is what AMD meant by "OC'ers dream..." ;)

http://forum.hwbot.org/showthread.php?t=142320

The steps include unlocking the Compute Units to enable Fury X grade performance, enabling the hotwire soldering pads, a 0.95v Rail mod, and of course the trimpot/hotwire VGPU, VMEM, VPLL (VDDCI) mods.

The result? A GPU frequency of 1450 MHz and HBM frequency of 1000 MHz. For the HBM that's a 100% overclock. The performance goes up from 6237 points at default to 6756 after unlocking the CUs, then 8121 points after overclock on air cooling, to eventually end up at 9634 points when fully unleashed with liquid nitrogen.
Pics of the card, and all the mods needed to achieve this: http://forum.hwbot.org/showthread.php?t=142320

final results so far...

I'll just assume the extra parts needed and electrician ship separately?

Just leave out the part about ln2 too. Who cares you can't get these results ever in at realistic situation! It's a possibile oc, fury is now the best ocing card!

1450 on the core is pretty weak considering 980ti reference can hit that easily and under LN2 like this Fury over 2 ghz.

cool on 100%hbm overclock though

enlighten my ignorance,

why doesn't AMD release these cards already this way?

Yawn. Again, LN2 results are as useful as two left feet.

Because it requires liquid nitrogen to maintain these clocks.

Stupid LN2 results notwithstanding, you can't compare max overclocks between different cards and architectures. Meaningless comparison.

the OP says 8k points after on air overclock .. so you don't actually need LN2 to get nearly 2k and 33% boost.

since AMD isn't really doing that well compared to Nv, why not release the cards fully unlocked?

LN2 is a fun experiment, but I'd much rather see 30%+ OC that is sustainable IRL. I think the cooler (OMG pun!1) aspect of all of this tweaking is that people are successfully unlocking their non-X Fury cards into full Fury X cards.

Here are the 3DMark numbers according to the thread:
  • Stock Shaders (3584 Shaders/224 TMU) / Stock Clocks (1000/500): 6237
  • Partially Unlocked #1 (3776 Shaders/236 TMU) / Stock Clocks (1000/500): 6505
  • Partially Unlocked #2 (3840 Shaders/240 TMU) / Stock Clocks (1000/500): 6615
  • Fully Unlocked to Fury-X (4096 Shaders/256 TMU) / Stock Clocks (1000/500): 6756
  • Fully Unlocked to Fury-X (4096 Shaders/256 TMU) / 10% Air OC (1100/550): 8121
  • Fully Unlocked to Fury-X (4096 Shaders/256 TMU) / Voltage Mod & LN OC (1400/1000): 10033

The outlier here is the 8121 score (a 20% increase) with only a 10% OC on air. It looks like tesselation is set to off ("TESS OFF") for this test for some reason. So not apples-to-apples.

Edit: That 1TB/s memory bandwidth with the 100% HBM overclock is pretty amazing.

thats what i mean.

i'm pretty sure that a good number of these cards are bought by ePeen people who will not do any mods to it, at most a run of Afterburner. So isn't AMD gimping itself by releasing cards which are running stock well below their potential?
or does the 980 series also require unlocking to get the most out of them? (i'm talking volt mods, not just OC)

I don't get it. This is just a Fury unlocked and overclocked? Which Fury models unlock? Can I get an unlockable on water? And is that what I am seeing 290x CFX performance with a slight OC and unlocked?

Fury isn't locked. There's just a lack of software currently available. W1zzard from TPU is working on software (I believe he does TriXX for Sapphire), and apparently so is Asus. I'm sure there's others too.

The real question is when does Unwinder get it into Afterburner. I can get to 1125 on my Fury X but I want to get to 1200 hopefully with +75 or +100 mv.

1125 on the core is pretty good from what I've been reading. Do you get instant artifacts a notch above?

Have you tried the VRAM trick to clock it higher? (I recall it involved something like rebooting the PC and randomly it allows you to tinker with it).

Do not get artifacts but games crash fairly quickly.

Have not touched the VRAM

Then what am I seeing about shaders and TMU's increasing?

Sorry, I thought you meant voltage locked. As far as which Fury models you can unlock to FuryX, that's complete luck of the draw. We haven't seen enough of it to know whether or not it's many, all, or most that can be unlocked. There should be a thread on some forum where members are doing it and you can get an idea of the odds.

We used to have threads like that here, but it seems like those days are gone here at AT. :(

Thank you. I thought I was seeing an unlock. Reminds me of the 9500 NP to 9700 Pro days.
