Upon purchasing, I removed the air cooler, installed a water block and ran the card on the liquid bios with a 400A power play table. After 3 years, the card started stuttering and re-flashing the air bios fixed this. Also, this card melted a CableMod 8-pin at some point, so I hooked up the EVGA cables. Yes, its a dodgy card but I'm impressed you were able to repair and mod it so quickly and easily. I am overly excited to see you run it under LN2!
Where did you find the liquid FE bios?
@@jon4715 Techpowerup VGA bios collection, but newer AMD drivers don’t play well with bios flashed Vegas (hence the stuttering).
@@El_Marzocco Got it. I could never find a FE Liquid bios, still have an FE Air under water. I never messed with 64 Liquid. Seems like it's not worth the hassle. Funny our FE's are only using Pro-ish? drivers now, no way to use Radeon gaming drivers in the interface anymore.
@@jon4715 Oh? I've been away from Vegas for a while.
@@El_Marzocco Good for you. I like the pro drivers and havent felt compelled to upgrade. I had a Radeon VII but sold it.
Also it looks gorgeous with that Frontier cooler!
I'm still running a V64 in my system today. Got it second hand, never used, at launch from a guy that accidentally bought too many for his then mining rig (2017 mining boom). Best hardware deal of my life. Running under water - has massive coil whine but it is what it is - performance is great.
I got mine new, near launch literally weeks before that very same 2017 crypto boom kicked off. normally i would never buy at launch, but frontier already being around and the crypto boom telegraphing its instatiable demand for gpus make me pull the trigger.
would like to upgrade, but god damn the prices now, and given most GDDR6/x gpus will roast even at idle if you run multimonitor and 144hz 1440p.
@@anasevi9456 haven't even checked my Vega but I'm running 1440 144 as my main and a 2160p 60 as a second monitor. Haven't noticed any heating issues.
I still like the design of the card. Even as unholy Blower!
its not so bad, the pitch of the Vega reference blower is more of a soft whoosh, than the shrill whine you got with the 290x and 5700xt.
Got my Vega 64 @1680mhz core and @1100Mhz VRAM pulling ~400W on water for a few years, really awesome card for overclocking and easily one of the best reference PCBs ever released with 12 phase VRM, dual BIOS, triple native Displayport, GPU usage LEDs, unlimited soft modded power limit etc.
It`s nice to see vegas on recent content, I`m still using one since 2017 lol
True, I got mine April 2019 from a guy who changed his mind after a few weeks and switched to a 1080 Ti. Back then they were the best value. And although I was caught by surprise by the dishonest TDP and it crashed in older games, the undervolting and memory overclocking possibilities made me like it after a while.
Frontier Coolers were beautiful, shame AMD decided not to make Frontier Editions for their RDNA GPUs (i'd love a 16GB 5700xt or a 32gb 6900xt with the blue and gold theme, just because).
I wouldn't mind having a 16gb Vega 64.
@@juniperburton7693 They're called "Radeon VII"
[laughs in Radeon Pro W6900X]
i did this to allmy cards, even laptops, filled some empty spraces for filtering caps, asus strix 1070ti could go from +300mhz memory to 650mhz, just for caps, and i could go higher with gpu 2080Mhz with stock voltage.
yeah I had a 1070 and it also had a crazy uplift in mem clock from extra caps.
I run my 1060 mem at 10GHz :-:
@@mmllmmll22 yeah and i overclocked my casio calculator and i beat 3090 by far.
I did buy a elmorlabs we talked about in your stream, those 90s will be all cramped ahah
Awesome, gonna be a good morning
frontier shroud is beautiful!!!
I love my Vega FE that sits in my server. It is such a pretty card
I did this on my 5700xt, found a few broken ones, didnt realize it til I put a water block on it. Asrock wouldn't rma it cause I opended it lol, so I did this same thing but.. some of them was added on extra without knowing cause I couldn't see it lol. now I have a way better scope. love this stuff man. keeps from thinking I'm crazy
Wish I could run newer drivers on my VegaFE, the old regedits dont work anymore.
Same with my v64. Just listing the power limit was giving me insane uplift performance under water.
Hey Buildzoid, wondering if you take vegas64 and repair them ? I have a bunch of them that work perfectly fine but (IMO) they have a faulty temp sensor. Card runs 2-30c more than my other vegas at start. I have repasted them and the problem is still there. Thanks for your content! cheers
Got a nitro+ 56 flashed with 64 and just picked up a ocformula6900xt. Love my vega
Most Vega users: Blower fans sucks
* Me with an RX Vega 64 reference on my gaming PC and a RX 480 8Gb reference on my secondary PC * 👁__👁
What kind of voltage would you consider 'safe" under ambient water? I'm planning on doing some practice on a dead R9 Fury and then trying this (the SP caps and the i2c header) on my own Vega 64. Also, more of a theoretical question, would you be willing to run more voltage based on bringing the overshoot down? Or are the time periods so small that max 'safe' voltage doesn't really change?
Vcore upto around 1.3V is probably fine if you can cool it. I wouldn't push the VRAM past 1.4V(and even that is probably pushing it).
@@ActuallyHardcoreOverclocking Thank you
@@DeBlackKnight Just stop at 1.35V for vMem.
My Gigabyte RX Vega 56 8GB OC card boots up just fine but artifacts then freezes a few seconds after I try to run a game or run video editing software but here is the kicker, it will run fine with Heaven benchmark. What are your thoughts? Have you ever come across a video card that does this? Can it be fixed by a professional electronic technician? Also I think this would be cheaper than buying another one considering that buying a completely dead card would cost no less than $400 on E-bay
264W bios is Vega LC and AIB air cooled designs. 220/200W is reference design V64, so nothing weird at all here. And yes, LC bios is broken on non-LC cards (has been for a while). Other bioses do work fine, provided they come from a card which is similar-ish (i.e. same VRM) to a reference design.
Removing the rear Io shroud makes it a lot better
Curious about what is said at 1:00 about using the wrong BIOS on cards. Does that apply for Navi 10 as well? Does Flashing a 5700 to a 5700XT cause issues now? Or even flashing a 6800 to a 6800xt BIOS like people are doing now. Did they screw people with new drivers?
IDK about newer cards since the only card I have that's newer than VEGA is the 6900XT.
so far not yet mine is running fine 5700 running xt bios
Would these modifications help with the amp spikes these cards get?
not really. This is on the output side of the VRM. The spikes would be more about putting caps on the input.
I’ve wanted to see someone do something like this for a while. I also want to see someone use vacuum tubes in place of something. Surely they could be used to mess with the power distribution or something.
I have a reference v64 on water and think I got very lucky with my silicon. Back when power play tables worked, it was insane.
If I didn’t need to baby this card in fear of killing it in this GPU market I’d live to mod it to unlock its full potential.
Any chance you've got a spare Vega blower cooler, I could possibly buy from you. They're very hard to find
Dang, I just moved and I binned the cooler that came with the card in the video. It was unused and had all its thermal pads.
Liquid bios dont work on normal card anymore. Use the MSI air v64 bios its the best one.
Works on mine. I got liquid bios on msi V56
@Actually Hardcore Overclocking Thanks a lot for the video, I want to do the same modif to my card, can you help me to buy the components (Ref or better a link from a supplier). Thans for your help.
I actually love that stock backplate! Currently rocking the stock Gigabyte back plate on my RVII with a Barrow water block. But I did ghetto retard things and put two 1.5mm layers of Fujipoly I had laying around on the back of the die, and stuck a big 20mm heat sink onto the Fuji. Now I have a rather ridiculous gap between my core temp and hot spot temp, since that ghetto stuff sometimes actually works! Can't say it helped with clocks, but I can see 2060-2070mhz in game / benchmarks consistently, using MPT to set the power to 350W, cause I'm not as smart as BZ.
I’ve got 4 vega fe’s in a threadripper but only ever used all four cards at once for mining. Don’t mine anymore though.
vega 56/64 cards are insane on eth and ergo right now. I get 55 mhs (130w) on eth and 200 mhs (180w) on ergo for 1 vega 64, you should consider starting them up
@@dawre3124 I did, but I made the mistake of using ek thermal paste. When everything was new they held ~50-60C easy. turned down to about 900w total wall draw. now they rapidly over heat and it would be a huge job to repaste them.
@@NavySturmGewehr where you from? if your from eu id buy the cards from you xd
Hey Buildzoid, just used a random SPPT on my Sapphire Vega64 and it seems to work fine. Could you elaborate on how to rip the specific power play table off the card?
basically the same method as this: czcams.com/video/wNSIyLI-LEc/video.html
@@ActuallyHardcoreOverclocking thanks mate
I have a launch day Vega64 reference card, it has 200/220w bios roms.. I thought that was normal lol
Yes, reference is 200/220.
I made sure to look up the different BIOSes on TechPowerUp because the Strix 64 I bought second hand is supposed to have 240/260W BIOS options. Person who owned it before me had messed up the 260W BIOS...
blower are only good on server & very big multi gpu setups
The standard Vega 64 and a lot of AIB cards have a 220w power limit, only the LC and the nitro+ had a 264w bios from what I've seen. Why I'm disappointed as I'm power limited on my reference card that's water-cooled now.
Pretty sure the OC bios on my PowerColor Red Devil is ~260W
Thought you could still regedit the power play table to increase power limit slider
@@benjaminmcintosh857 this was patched in old driver, can still get it to happen but the card will down clock to 400mhz every 3-4 seconds and I haven't seen a way to patch it.
@@Smithy2222 think my comment got deleted. I tried again using newest driver and overdriventool and was able to successfully make it work on 64 flashed v56
@@benjaminmcintosh857 oh that's on 22.8.1? Also have to run 3D mark just to be sure about the clocks? If it's running fine I'll be doing this when I get home today aha.
5 ms/div and a 1x probe isn't going to cut it for the power delivery network of a 2 GHz chip. If you could see anything significant at that scale, it'd be a bigly problem...
Intel's measurement standards for 4GHz+ CPUs are:
"The voltage specification requirements are measured across Vcc_SENSE and Vss_SENSE as near as possible to the processor with an oscilloscope set to 100-MHz bandwidth, 1.5 pF maximum probe capacitance, and 1 Mohm minimum impedance. The maximum length of ground wire on the probe should be less than 5 mm. Ensure external noise from the system is not coupled into the oscilloscope probe."
From page 120 of: www.intel.com/content/dam/www/public/us/en/documents/datasheets/8th-gen-core-family-datasheet-vol-1.pdf
My piece of coax probably isn't meeting the 1.5pF capacitance requirement but other than that it works fine and produces usable data.
@@-szega I've messed with using lower time divisions and it doesn't really change the max and minimum voltages measured (even when using the trigger to check for over and undershoot). So that's why I normally take my measurements at 5 or 10ms per division.
Also the intel overshoot spec is just how much the votage can exceed spec and for how long. Intel has a VRM test tool so I guess the TDP and virus modes are reffering to the configuration of the VRM test tool.
Blowers suck, BUT what about the 3000 Founders? They are half blowers....
They arent really though. They kinda blow but it's a downdraft fan that happens to force air along a similar path as a blower type design. It really is downdraft all the way.
@@fVNzO But Buildzoids problem with the Blower was not with the Fan, but the Size of the Heatsink that was cooled by it ^^. The FE shortends that bit.
@@gucky4717 Okay but the only context im using here is your initial comment i have nothing to add about buildzoids opinions on blowers.
Why do you say "half" do the have an opening on any of the other sides or the back.
@@abstractapproach634 I think he's referring to the back fan which blows out the back over the pcb. The outermost fan blows through a fin stack off the pcb.
NICE AWES0ME C00L_🍨 VIEW *
That won't fit in a ITX board with a full size vrm heatsink.
The air-cooler doesn't suck.
It blows😏
Steve from GN would edit 7 minutes from this video, because he is a conformist.
OLD GPU LOL
That's a Vega FE, not a 64 😉
