AMD GCN GPU Disabled Stream Processors Unlockable with Software
Interesting news, it seems that if you own a recent GCN based Pro series GPUs from AMD (Hawaii Pro / Fury Pro / Tonga Pro / etc) is now possible to unlock, at least some of the disabled parts on the GPU.
Over at the OCN forums a user called tx12 released a little utility called CUinfo and this tool can be used to read information about active and disabled CU units in Hawaii, Tonga and Fiji. Basically the tool reads out the GPU core configuration, which can be altered and then flashed back into the BIOS with another tool and some modification. The current status of the tool is that it only reads out info, and you will have to edit and re-flash the BIOS yourself.
Cards like R9 Fury non-X, R9 390, R9 285 could be enabled with more CUs, I say COULD, as there are two methods used by AMD, laser cuts (prevents this from working at all) and through firmware, which would be this methodology.
Be warned though, GPUs are binned, defective CUs could be disabled for a reason, if you enable them ... who knows that will happen. Basically you will be gambling with your graphics card. |

This tool can be used to read information about active and disabled CU units in Hawaii, Tonga and Fiji.
Tool is based on public sources with some amount of guess-work. Any data interpretations are not official.
Tested on all supported chips.
It's still interesting to get output from cuinfo tool from ANY Tonga and Fiji / Fury chips.
How to (try to) unlock cores on unlockable Fiji chip.
Currently applies ONLY to Fury Air cards with Fiji PRO chips.
Fury X owners won't find here anything useful. |

As a response to the above post by Beta?
(But maybe I just misunderstood.)
The 290 compared to the 290X or the Fury to the Fury X uses lower binned yields with a certain amount of units disabled, this is strictly related to the GPU itself and not the VRAM.
It's a good thing that these can sometimes be re-enabled but many of the newer revisions will likely use the method where the disabled units have been laser cut and as such can't be re-activated compared to if it had just been disabled in the firmware/bios.
(I'm surprised that there actually were models that could be unlocked, thought it would all be laser cut these days.)
Essentially you could via this and perhaps a bit of overclocking turn your 290 to a 290X or a Fury to a FuryX although as these are lower yield models results will vary a bit and some of these units could even have been disabled due to defects or other errors so you are taking a bit of a risk by trying to re-enable them again although when it works it's a nice way to boost performance further without the actual cost involved with buying the top-end GPU models.
I'd give it a try myself but this is a non-reference board that came out a bit later in the life of this particular GPU model so it's almost certainly laser cut. |
Sorry JB, its more of a wonder why it was reading more used up card ram than I obviously have, the gtx 970 does not have more than 3.5 + 5 slower access onboard ram right?
I have a feeling the option in say advanced warfare where you can select "fill up remaining card ram with texture memory" is doing something really odd, the afterburner readout must be at fault I guess, but on a different note would be nice to unlock such restrictions on the card like the fury etc has seen done of late, of course one is gambling with wether those things were locked due to being faulty in the first place or possible that they are all fine and will give you better performance. |

Ah I see, that could perhaps be the Windows thing where VRAM, RAM and the page file combine into total system memory which you can see via e.g "DXDiag"
I'm not sure how Afterburner reports memory, I know you can set it to monitor both RAM and VRAM usage but I'm not sure if that were to show a combined total value like in your screenshot.
(I use Afterburner myself but with hardware monitoring disabled so I don't have much experience with the more advanced features of that program, for me it's mostly a basic framerate overlay and FPS limiter with the ability to record footage or grab screenshots, AMD also has a framerate limiter now in it's drivers but some "genius" tech guy decided the slider should be from 55 to 90 instead of say 30 to 240 and it only works on D3D10 and newer at the moment.)
EDIT: Now I see what you really meant, total usage for VRAM peaked at 4723 MB which exceeds the 3072 MB available from the 970, that's probably a memory leak (Batman Arkham Knight for example, easily fills up the 4 GB my GPU has and once right before it crashed it had nearly grabbed 10 GB RAM too of the 16 I have in total.) and the normal behavior when this happens is that data is swapped from VRAM to RAM.
(Usually with stuttering as a result although it gets even worse if RAM runs low and it has to use the paging or swap file on the HDD.)
It can also be the thing you mentioned which for example is used in Advanced Warfare to fill up RAM usage to a certain degree (Which in that case I believe was just empty data to try and slow down debuggers and the like.) or it can be like in Shadow of Mordor where the game will reserve (Doesn't mean it's using it.) up to I think it's 85% of your total VRAM by default so people with 8 GB VRAM and above saw the game using over 6 GB but it's being used as a sort of buffer for texture streaming.
(That's not to say the game doesn't require a lot of RAM and VRAM which it definitively does with higher screen resolutions in use along with the high-res texture pack but there's still the memory reservation thing.)

The reason early batches as well as later batches of GPU's that are equally good are binned differently is because nVidia and AMD have to continue to supply GPU's for all their SKU's, esp. the latest generation and therefore many GPU's out there have been artificially "snipped" to fill the orders for the lower level SKU of the same GPU. If it's very early in production they may not have had time to implement any laser cutting at the foundry and implements it in the firmware.
This is can be a double-edged sword. While they may have to use better yields to fill lower level SKU-orders they will also bin slightly defective GPU's in the same tray and thus the "lottery".

Yeah, that's also the thing with the ASIC measurement right?
(As a rough way to check on quality though this particular thing seems mostly for potential overclocking limits.)

About 4-5h of GTA V with these: http://imgur.com/a/jeyxO settings.
The card is rock stabe and I didn't had any graphical issues. I need to test with some other games before announcing these as the highest 24/7 clocks this card can run on.

I'm planning to get GTX 970 Zotac does anyone knows whether its not recommended as Zotac provides 2+3 years of warranty compared to MSI and Asus

i would stay away from zotac as i heard some horror stories about them on another forum, especially about their 2+3 year warranty bullshit. just get trusted brand like MSI or Giga. I wouldn't get Asus this time as they had some cooler issues with 980Ti.

If you don't deal with the crappy shops and use the RMA instead you can also get away with more.
Been a few years since I actually dealt with a shop for a return.

| Quote: | | Overclock any NVIDIA GPU on Desktop and Mobile with a New Utility |
| Quote: | An author called "2PKAQWTUQM2Q7DJG" has published a fascinating little article today on his/her Wordpress blog entitled, "Overclocking Tools for NVIDIA GPUs Suck. I Made My Own".
What it contains is a full account of the process of creating an overclocking tool beyond the constraints of common utilities such as MSI Afterburner.
By probing MSI's OC utility using Ollydbg (an x86 "assembler level analysing debugger") the author was able to track down how Afterburner was working.
“nvapi.dll” definitely gets loaded here using LoadLibrary/GetModuleHandle. We’re on the right track. Now where exactly is that lib used? ... That’s simple, with the program running and the realtime graph disabled (it polls NvAPI constantly adding noise to the mass of API calls). we place a memory breakpoint on the .Text memory segment of the NVapi.dll inside MSI Afterburner’s process... Then we set the sliders in the MSI tool to get some negligible GPU underclock and hit the “apply” button. It breaks inside NvAPI… magic!
After further explaining the process and his/her source code for an overclocking utility, the user goes on to show the finished product in the form of a command line utility.
There is a link to the finished version of this utility at the end of the article, as well as the entire process with all source code. It makes for an interesting read (even for the painfully inept at programming, such as myself), and the provided link to download this mysterious overclocking utility (disguised as a JPG image file, no less) makes it both tempting and a little dubious. Does this really allow overclocking any NVIDIA GPU, including mobile? What could be the harm in trying?? In all seriousness however since some of what was seemingly uncovered in the article is no doubt proprietary, how long will this information be available?
It would probably be wise to follow the link to the Wordpress page ASAP!

Looks like a DOS version of NV Inspector?
Anyway.
Here in UK, we have a 14 day 'change your mind' policy. So, I can 'change my mind' up to that period, for a FULL refund or replacement, no excuses
Of course, I was out-with that period with my Zotac, so I had to do the 'dirty'.
You see, one of the other benefits of buying a 'reference' board, is that they all look alike, so I swapped it over, outside of the warranty period, and thus, I end up with a new card and warranty 
You have to have the cash to buy another, but it gets refunded pretty quick here.
So, if you order an MSI board, it may just be a Zotac 
Life is tough, yup, but I've lived long enough to know the tricks of the trade.

Also you cannot even open the box if you want to change your mind. |
exactly. 14 days is such a bullshit. when i had noisy GPU i told the store about 14 days thing and they were like "but you opened it". no fucking shit, ofcourse i did, this is gpu, not a painting, i didn't buy it to stare at it. and how was i supposed to know if it has defect without using it. i don't know why computer hardware stores get preferential treatment and get except from normal returning like other stores. if i buy a lightbulb or a powertool i can return such items without questions asked and it takes 5 minutes to get your money back or exchanged to another item. but not for computer hardware, it's like they are above the law or something.
