[AHOC/Buildzoid] Soldering more input filtering caps onto the RX 6900XT
-
kudos to this guy. Never going to do that myself, but amazing work.
ID: h1w29mjID: h1wly4vIt's probably less stressful when you have multiple of them and/or don't have to pay for them. lol
-
So, what does this do?
ID: h1wapanCleaner and more readily available power for that XTXH chip.
ID: h1w4qr0It filters the input
ID: h1w8f3yELI5 please

Zoid is the reason I started and have had so much fun dickin around with my Vega 56 card. Still have it in one of my rigs and if your into playing around with the board, and bios flashing and the like, you can squeeze quite a bit of performance out of em. Its running my daughters 1080 144hz setup quite well still to this day. Cant wait to get one of the new AMD cards. The 2080ti(Tie) on my 1440 144hz rig is just overclocked, haven't really dug into it, but I did pay retail (couple years ago) for it, Vs the 200 I spent on the Vega. I kinda don't want to mod the ti as much, mostly because it looks like I could sell it and prob get my money back on what I paid for it...lol....

ID: h1we0q9Lol @ not understanding what you've read...The sentence reads "if you're into playing around with the board and bios flashing and the like..." which is still a far cry from all what Zoid does, but I also stated that he got me into this. You were right , I'm no where close to what Buildzoid does, and never stated that I was, just that he inspired me to start. Reading comprehension is a very important skill, work on it.
ID: h1wd6lcHe said that buildzoid was the reason he started. He never compared himself.
ID: h1wueknYou lack reading comprehension.
You're a jerk.
-
Dang, I have a similar set up as him, and he's getting about 5k more than me in firestrike extreme
ID: h1vjmuxIf your RX 6900 XT doesn't have the Navi 21 XTXH GPU, which features higher clock speed limits than the Navi 21 XTX, then you won't be able to match his score.
ID: h1vka0wYeah, I just have a regular red devil on water and a silver sample 5950, I didn't think the gap would be that wide. Even more impressive since he's running on air.
-
If Louis uses 1 MicroPaul of flux, then Buildzoid must be down to the PicoPaul.
-
Electrical Engineer here. Why do you think this is a good idea?
Edit:
- Can not see any ESD grounding of person nor workspace
- Extremely shitty soldering
- How do you plan to wash off the flux? Flux is very corrosive, and looks like it was just left there
- This job would be a REJECT at any rework desk.
Also
- Dont add caps with liquid electrolytes. Use Solid caps.
- If you have coilwhine, replace on warranty or pot coil with silicone
- The DC-DC converter is usually optimized enough. Not many MHz to gain
- Many other areas to improve performance before this should be attemptedID: h1x49o9Higher clocks and less coilwhine.
ID: h1xj0o9To quote his pinned comment in the video:
So just did the first FSE run with the card. The coil whine is basically gone.
WHY can't manufacturers just do something like this themselves? They know people hate coil whine, they know a ton of people will RMA (fruitlessly) over it. Why not skip the bullshit and have clean power running through their GPUs so people are satisfied and not wasting resources returning perfectly fine GPUs?
Oof I just realized who I replied to lol well done on the mod sir.
ID: h1xtxd0I'm really interested in the fact your older cards still run fine, surely this puts more strain on the MOSFETs?
ID: h1yjo34EE here as well.
that matters but its his money to burn if he kills it. if it works its not shitty soldering it just don't look nice. He's an overclocker, the journey isn't pretty he's just chasing benchmark results and temporary stability (enough to repeat a benchmark / stress test) so he isn't thinking about how this card will fair in 2 years time. depends on the activators used in the flux and its commonly takes years to effect a typical PCB. Good thing its not work. adding random new caps with mixed types, ESR, etc is indeed dumb. So much better to replace each cap with the better more ideal ones that accomplish the same results than adding more caps willy nilly without thinking it though. I've seen coinwhine cards get RMA'd or replaced with equally as whiney graphics cards.
consumer hardware doesn't really get all that dialled in and the margins are crazy tight for the board partners so there are lots of GPU mods just like this to make up for the 4 cent cap being used in place of a the 6.7 cent cap (pre covid) and even more extreme VRM replacement mods out there. Yeah but he doesn't get to make a video that gets more than 5k videos. That looks like its his business model and end goal here.ID: h1z7bm4Thanks for your critique. I still stand by my points.
ID: h20rvkzI've actually dailied modded cards and motherboards. They hold up fine for years.
Replacing caps on any high power rail is a total waste of time in my experience. Though I'd love to see an example where replacing caps works better than just adding more in parallel.

Even I am an electronics engineering graduate and knowing what he's doing.....I am not dare to work this out myself, just too expensive.....!
ID: h1y251hKnowing the theory behind electronics and actually soldering things are different skill sets.
ID: h1y310lSame here, when I hit the pascal wall of my old 1080ti and I can't really cram more cooling or good old MOAH voltage.... I just can't justify frying my 1080ti, kinda emotionally attached to it at that point.
ID: h1y3xjuMost 1080Tis are really easy to mod because the voltage controller on them is analog and there's a public datasheet for it.
-
Dunno if I should laugh or cry at people making bold claims about how this turned a mediocre card into a top air card.
Did you guys forget he's using EVC and pushing like 80mV more? Did you guys forget this is an H stepping so it's already a top SKU?
This mod alone does basically nothing to performance.
ID: h1ziw384th fastest single-GPU FSE score in the world, without LN2. You think he's the only person to try shoving my volts into the core?
ID: h1znhwxCheck the leaderboards and how many of those cards are XTXH.
Check how many are using EVC2.
If you think a cap mod made him 4th best you're out of your mind.
I'm 16th with a 5800X and a XTX card.
Side note, if you're doing ambient it doesn't matter if the card is on water or air, if you don't hit throttle temps, which he's not even close to, then there's 0 advantage when you run EVC2 and basically override the Vdroop you get naturally by feeding it more voltage.
-
Well it's his gpu, he can do whatever he wants, even it's useless.
ID: h1v9g9vhis air cooled card is now beating all but 3 other overclockers in fire strike extreme. leaving many ln2, chilled, ... cards behind him in the standings.
ID: h1w0ftqSo he's getting higher clock out of it or something else?
ID: h1v1c0gActually it's not useless. Buildzoid did say that he was able to OC the card a bit higher by adding more input filtering caps. Apparently AMD reduced the input filtering on the RX 6900 XT so much (in comparison to even low end cards from previous generations) that it actually impacts OC potential.
ID: h1vnp4gApparently AMD reduced the input filtering on the RX 6900 XT so much (in comparison to even low end cards from previous generations) that it actually impacts OC potential.
Huh, that seems strange, I can't imagine that those components cost all that much to add to a board. If an extra five dollars in, erm, capacitors(?) can tack on a few more mHz, then why not?
ID: h1wvpeduseless
He made his card turn from a mediocre over clocker to the best performing air cooled RX 6900XT
ID: h1x7kduit was pretty strong to begin with just not able to beat watercooled cards.
-
If this works that well.. Why aren't the card manufacturers doing this? They throw money at all sorts of things in the name of overclockability. This seems cheaper than many
ID: h20rg9mThey are doing this. Asrock's OC Formula and MSI's Gaming X 6900XT have way more input capacitance than the reference AMD design.
-
It’s especially stressful watching this knowing it’s his only 6900xt. Dude has grown his follower count 3 fold since I subbed but he deserves millions, so we can be trillions more. We could storm Eden and retake her!
-
Do you have some measurements to quantify the difference with and without the extra caps?
Would be curious to see where the design could be best improved.

I was sweating watching this. That's an expensive card. But good for him. I'll just live vicariously through him.
