RTX 4000 repair

[@n3rdware]

Impressive how you got this card back to life! That custom cooler solution is actually developed by me. You're probably right in advising people not to such solutions from your point of view. But I do want to point out that what you mentioned about over-tightening the screws is impossible because the screws are 'shoulder' screws, blocking themselves at the exact required point. This is actually used in most gpu coolers and isn't any different from the original cooler. The 'posts' you mention are just replaced by longer shoulders.

[@drewnewby]

@n3rdware You should consider using posts. Shouldered screws can be lost, and replacements can be inaccurate.

[@n3rdware]

@@drewnewby Posts require shoulder screws just as well, you can see them after they are unscrewed at 1:20. My screws are almost identical to the original ones, just with a longer shoulder.

[@drewnewby]

@n3rdware That's the point, if you use posts, the original spec screws can be used, instead of longer shouldered screws. Replacement coolers should use the same design if at all possible. I assume the cost of the replacement cooler more than covers the manufacturing cost of including posts. Sounds like a cost save on your end.

[@n3rdware]

@@drewnewby That's a whole lot of assumptions in just a few sentences. It's actually simple: I prefer not being dependent on third party hardware that I cannot replace myself if required. If my screws are lost, I can replace them. If your original screw is lost, I can't, and Nvidia probably won't.

[@drewnewby]

@n3rdware That's fine if you're milling / printing your own solution, but you're selling these. Everyone replacing the stock cooler has the original shouldered screws as spare, if you use posts, instead of what you've sourced. It's no assumption, and common for boutique kit like this to deviate from spec for all the reasons I've mentioned.

[@bdogsp0012]

What I learned today is if your gpu is working fine, leave it alone. If you want to practice fixing gpus, buy or find dead ones to practice on.

[@coc1841]

I leaned that if my GPU dies, I have to add a zero ohm resistor somewhere.

[@sakikogookheng]

@@coc1841 I also think this is the lesson to learn from this video

[@TheRealName7]

I opened my brand new card cuz the thermal paste they put is dogshit. I always gonna start opening my cards and applying ptm7950 because it performs drastically better, has more lifetime, doesn't experience pump out like normal thermal paste but most importantly the temps are significantly better.

[@noth606]

@@TheRealName7 Also arguably voids your warranty immediately too, so that's also one less thing to worry about. You save time and space since you can immediately throw the receipt and box etc in the garbage, you won't need them for RMA ;-).

[@TheRealName7]

@@noth606 you know the void warranty stickers are illegal? And actually the government cracked down on gigabyte, asrock and zotac for it. So no, under the law my warranty isn't void if i need to return my card for any issue that happens outside my control they have to accept it and inspect it and prove the damage wasn't caused by user error.

By far the best fix!!!! ~_~ Can't wait to send you my first Evga RMA! lol Keep it on!

[@Negiku]

One of my dream cards for small form factor build. Good job. Performance is around the same as a 3060 i believe. Looking at the temps, it doesn't seem to even need that custom cooler.

[@mikukumiku]

I followed a video hinted by someone else in the comments, and apparently the custom cooler is made to reduce the footprint of the card since its stock heatsink causes it to occupy two PCI slots. People who buy this custom cooler are apparently using it to make ultra compact PC setups, and reducing it to occupy just a single PCI slot is the goal.

[@Suresh_Pillai]

Excellent work Tony.. nicely done. These cards are utilised mostly in DELL/ Lenovo micro workstations/ servers.

[@noth606]

They are also out as retail products mostly PNY branded, but I think "PNY" makes both the retail and OEM boards so aside from the sticker/part number there is no difference. Maybe vbios vendor string. Not 100% sure now, but I think all the cards are physically manufactured by the same factory whose name now escapes me, one of their brandnames being PNY but they have others too.

[@Vile-Flesh]

Excellent repair! I wish the A2000 cards had a protective backplate like this RTX 4000 has.

[@kepler104]

Whole video i am thinking there must be a formula for figuring out the correct resistor value as we know the voltage on one end, but probably that formula will have to include something from the controller side which we dont know of. Good video

[@raiko3412]

You're absolutely right. Practical troubleshooting, especially with complex electronics like GPUs, often involves more than just applying formulas. Real-world circuits can have nuances and interactions that aren't immediately apparent or easily captured by theoretical calculations.

[@kepler104]

@@raiko3412 Yeah would have been easier if there was a public datasheet for this chip (there isnt)

[@JayBigDadyCy]

The lesson is - don't ever buy a blower card. The lower price isn't worth it. I had a blower 2080ti. The sound that thing would make at times was helicopter level. I looked into after market cooling solutions. Repasting helped greatly, but it still hates anything that uses UR4+ or anything like PoE or building games that have a ton of sprites. Ended up buying a 4070ti instead (went with the Gaming Trio version. I recommend it.) and I have zero regrets. I can't even give that 2080ti blower card away lol

Some other cards use that GS7222 controller also, you could have checked your donor board pile for those.

[@u9Nails]

That little card has 20 GB of RAM?! Fancy!

[@quantum5661]

vram is actually quite cheap these days, and the chips quite small, so they can totally do it but video card companies love artificial scarcity and product segmentation. easier to get people to replace their perfectly good hardware if the next gen version has 2gb extra.

[@lovegamesandtrains3194]

Nvidia doing more then 12 gb of vram on a gpu thats not for servers is rare and i say that because ppl use those for gaming even tho those are work cards for high end workloads

[@ranjitmandal1612]

💀

[@fleurdewin7958]

It has 20 GB of RAM , and without using any external power connectors. If you look at the PCB, there are 2 empty slots for 2 memory chips, potentially creating a 24GB VRAM card at this form factor.

They do sometimes come up for a good price, befriend people in IT. For a while I had a steady flow of current gen (at the time) Quadro RTX cards coming from an IT dept that upgraded every workstation they bought. ebay and new price is insane though. Nvidia missed a trick by not making a similar Geforce branded card.

[@JayBigDadyCy]

You don't want a blower card, trust me. Unless your PC is in another room, that is also sound proofed. The bulkier cards with their insane cooling is there for a reason. So it doesn't sound like a helicopter is taking off out of your house.

cant u just transfer those standoffs from the original cooler to the new custom cooler so then u wouldn't tighten the screws too much ?

Go lower resistance with a tunnel diode.

[@ianwolter6142]

I once burnt my whole RGB strips and fans by some cheap rgb fans and controllers from aliexpress, but it was user error, it had those molex connectors, and shorted the 5V rail with the 12V rail, so 12V on 5V LED is a big no. I still have the AIO pump, but it doesn't have lights QwQ

I was wondering since I had this problem (which was fixed by the company). Did you ever get a repair of a RTX4080 which does fine at pretty much every benchmark but would get driver crashes on like 50% of games? I'm still wondering what that problem with my card was.

Quadros after they removed the Quadro name are so confusing. I can never remember if this is newer, better or completely different to the RTX A4000... or the RTX 4000 Ada Generation. Maybe it is that last one, I can't remember. I could look it up but ehhh. Of course none of these are to be confused with Quadro RTX 4000 which was a Turing card. Nvidia need to bring Quadro back either way and give the cards proper model numbers.

no pad on one of the memory chips when you opened. on each side, on the heatsink as well as on the backplate. I own this card and there are 6 memory chips on gpu side and 6 on backplate side.
