Basic overview to use an Elmor EVC on Navi31
(Beware: this is a hardware modification, providing low level control; bypassing factory safeties. Every part of this could easily destroy your hardware, instantly or eventually)

Hardware: you will need to connect the PMBus to the EVC via soldering either wires or a pin header to three pads on the back of the card and connect to one of the I2C headers on the EVC (see image below)
View attachment 2605202

Software: Be sure you have the latest elmorlabs EVC software (at least 1.0.1.15 (which requires 0009 firmware))
1: Select the relevant I2C bus in left pane
2: Click 'Find devices' (typically this would auto-detect and populate any devices found, but for now, this is not functioning with these controllers; so currently you will have to manually set-up using the addresses found)
2a: To manually add, simply select the appropriate profile for the voltage controller and its associated address, then click 'Add', this will add the device to the left pane under the current I2C bus (see list below)

7900XT(X) uses:
-MP2857 on address 22 (Core)
-MP2856 on address 26 (Memory)
-UNCONFIRMED: I believe address 24 is also the MP2857 for SOC
[2856 and 2857 use the same parameters, so you can use 2857 for both until new version of software available]
-Any other addresses found are not useful here
*If your card uses different addresses, you will have to trial (wait for software update so you can verify association via reported voltages)

3: You can now click on the relevant controller/address in left pane to modify parameters (Monitoring on the 1.0.1.15 release is not correct)
Note: Controllers may have multiple outputs (eg. MP2856 on address 26; Loop1 is for the memory and loop2 is for the memory controller)
4: You can change parameters by selecting from the drop boxes and hitting 'Apply changes' (note these are not permanent and will reset if the card loses power: eg. cold boot)

The only relevant settings for 99% of us are:
-VID offset (simply a fixed offset of voltage output)
-Iout Gain (this functions as a current (amps) reporting offset, and thus is used to make the chip report it is pulling more/less power than it is; e.g. lower this value to increase power limit)

Please lower the Iout gain in gradual steps, these cards are capable of pulling tremendous power (I pulled ~800W at stock voltage)
Also since this affects the power reporting, power and current reading in software are invalid, I suggest having some way of monitoring estimate power draw (eg. Kill-a-Watt at the wall, or current clamps at the PCI power cables)
Just for know, excepted soldering, it possible to use like "glue" kapton tape" or anythings else for have the wire or pins touching the pad ? For keeping warranty.
 
I’m glad it’s happened as It means I have no chance of competing so I won’t even bother wasting my time trying. Dread to think how many hours I’ve wasted running Speedway etc. Now I can focus on YouTube gaming videos. :ROFLMAO:
Damn I almos just bought a water block and a evc 2......uhg cant...

...dangit....no soldering, if I could get a nice bios flash option or some tempvmin ppt action...i'd jump on it....Not that I dont trust the 2 8pin + socket to provide said 600watts... i've done it before on lesser hardware....But its just not worth if I f it up..I know i'd just say **** gaming and run my onboard gpu and I dont want to give up on the pc master race yet, not with amd making interesting hardware......... .meh oh well, I just cant justify it for another 10%..;..when it plays everything with ease damn near stock...

But yeah, shifting gears quick for a mini rant on ya LTmatt, sorry bud :( skip to avoid /rant......Whats with the XT hate...? Stupidty? ignorance or just straight the always mentally challenged stance of...its my team and my side, so now everything is like politics...all the excuses for this side.. and all the hate for the other.....But I digress.
anyways...... I see alot alot of youtubers, and ones people trust ....Such as Hardware unboxed selling y'all wolf tickets about the xt, and its legitemately provable they are litreally just straight lying for nvidia or whoever for increased doll-hairs or just that stupid, which i dont buy.,.. anyways HW unobxed literally posted a 1440p / 4k world war z - aftermath bench, where his bench has the xt at like 140 fps "overclocked" and the 4080 was like 40 fps ahead and widened the gap by more than double in 4k, even tho we KNOW the 4080 can choked at some high rezes cuz lower vram and its definately more a xtx competitior than an XT competitior given the large price tag..., (this was right after that aftermath xpac or addon dropped with the benchmark in game for WWZ....just like this past january) And whats worse.... he had on hand at the time the 4070ti to bench as well...But Nay...he put the xt against the then 1299.99 if u were lucky 4080 and said this was the result amd decimated -=- XT DOA -=- bad vlaue, blah bah blah, he is the slide from his video...:

... and I was like this dude full of ****, so i checked it out..bought the game.. and sure enough...not only did I nearly double his 1440p XT score(which I cant find the Screen for)hes out there telling the people that made him rich his audiences striaght lies for $ all while hes becoming wealthy for supposedly being a good source of comparison in the hardware world........its so sad, the 7900 xt is only slower than i guess ....what .....(half the 4080 in RT.. and barely in rasteriz if at all....so thats half a card.... .5 ...... the XTX and the 4090, 2.5 cards....so thats 2.5 gpus are faster....... like EVER... Right? And clueless people are calling it a dog **** card..

XTs real #s, which make his slide there look absolutely ridiculous:

Font Screenshot Software Terrestrial plant Wood

and btw this is with a 100mv UV 15% power and 0 for fast mem... so.. 15%, small uv and stock clocks... Netted me that way higher than 4k benchmark...

It so ridiculously absurd....Speaking about the XT you could literally say its the 3rd or 4th fastest card devised by man for public consumption, EVER thus far..... and be acurate AF right now...but for some terribad reason......if you ask around, ShouldI buy XT over... whatever,,,,You will be answered by tales of a weak and underperforming card... shouts of overpriced ad buggy! and murmerings of how it shouldve been called the 7800xt, because it fits there better......even though....the gap between 6800xt to 6950xt is quite large, and the XT to XTX. gap.. is definately more like 6900 to 6950, they were 100$ apart too... and about 5-10% diff in performance...

so THE TLDR even tho the numbers which are not hiden very well quickly make unboxedhardscrooge a liar and pervayor of lies for whoever he posts these lame amd hit peices for......(and not to mention several OTHER busted parses part of youtube videos that were created to mislead potential AMD customers and distributed by youtubers with millions of Subs). and remember hes lying to the same subs that brought him from a troll BS'ing on forums like us trolls......exactly zero ppl care mfor the truth..... They believe in their 'truth over facts' (joebiden quote?)..and well....its dog ****, the 4070 which is actually kinda dog **** for its price, is thought of to be superior.. when its not....outside of like speedway, KINDA...my xt even beats it in port royal. :ROFLMAO:

anyways ... sry about the /rant team, I dont get alot of geek time to post with the boys anymore.... but...to get back to your point, Yes... feels good to not be running a benchmark over and over for days in a row at a time, sometimes just for extra sauce, not even to regain a lost lead. xD.....we got an addiction me thinks...But looki, LtMatt is XFX friends.....Imma bout to start a few benchmark comps with a few new benches i found which are catching on, and fun to bench or look nice....SOOOOO.... look for me over there Matt and bring over big daddy xtx join in on the fun.
 
oh and one more thing to bug the thread about, is there any future to flashing for XT merc black owners.. or do we have the highest power and stock clocks...and that will be that? Cuz then I may have to evc2, maybe awhile down the rd....i want more for sure, just dont want to have to solder to this card....3 year warranty sounds good....Like the gyu above me said.. any possibility of not soldering? I know it may be a silly question, but I figure what the heck... maybe they've come up with something that wont fail and fry your card under load......also @gupsterg since i've been so busy lately I can only hop on.. make a few replies and back to the grind..... any news to a liquid XT AIB with some more go go juice in its .bin? I havent heard a word.. I know SOME xts even have 3 8pins yes? even though they arent even running the highest power..? lol

thanks guys. again sry for the rant

Currently for higher PL tier cards, like your Merc, there is nothing worth flashing. Only thing which will "Raise the limits..." is EVC.

I finally was able to crack the 33000 graphics score barrier in Time Spy with my Sapphire 7900 xtx pulse running the latest drivers. I think i am cpu limited for more.

Here my settings.
Pulse has PL slightly more than MBA, so that's what's holding back any gains from OC/UV.

Looking at how your LeakageID (ASIC Quality 36.4%) is so low, that is only reason why your getting 33K in a PL limited card. A higher LeakageID silicon would never get that score with PL your card has.

Enjoy! :) , that's nice silicon for sure IMO.

Man I just might evc this, any word if anyone has slapped one on an XT? I know there are 2/3 8pin versions.. but we both know... i'd be fine with 500-600w over just the 2 np....And is there any option other than solder? I mean i was talking to my uncle ...hes a career welder/electrician and he didnt want to say anything could 100% work, not having the board infront of him....But gave me some ideas...
 
Hello,

I installed the 7900xt Pulse yesterday and everything is fine, only the idle temp of the memory junction bothers me a bit, i've never seen it below 50°C. The monitor runs at 60hz, the CRU didn't help either. Everything else in the case runs at the expected temp.
Can I change something about this or should this be accepted in this series, in this GPU?

What are you asking and that is normal temps.

Those temps are normal. I would say 50-60c is normal depends on idle fan speeds, case flow, ambient temps. Anything above 70c at idle is high and might be caused by amd record desktop/high refresh rate monitor. Below 50c idle you got gem
 
My somewhat idle stock XTX nitro+ with 1 144Hz 1440p monitor and one 60Hz 1080p monitor

ambient around 24

(I do also have Arctic Liquid Freezer II 420 pulling air from radiator front pretty much right on the GPU )

EDIT: actually I guess you were looking at memory junction
thats a lot higher for me

Thanks for the answers. I don't really see it as a tragedy either, it just bothers me a little that a single value stands out so much. Perhaps because it does not measure on the surface, but directly in the silicon. And of course the Pulse is not a high-end card.
Other than that this card is perfect, at least for me. It doubles the previous 6700xt Nitro+ in everything, even though there is only a 5600x next to it. And most importantly, no cw below 200fps, there is also surprisingly little above it.

LMAO! *** is going in that AMDunboxed chart? Did they use the benchmark or was it from actual gameplay? Thanks for checking it yourself.
 
Yes still HW flash required for cross flash. XFX RX 7900 XT/XTX Merc Owners OP updated with EVC info. Will also add HW flash info to complement the SW flash section.
Whats the full name of HW flash? I would like to download it - thanks
