Summary
- It’s this one, when I got this it was very dusty and I had no idea it is actually the fastest GTX 780 (or at least in the GPU-Z database https://www.techpowerup.com/gpu-specs/inno3d-ichill-gtx-780-herculez-x3-ultra-dhs-edition.b2590). I took it for some kind of brash, lower-end model. However, I have found myself stunned by it’s great thermals and amazing core clock! It actually manages to outshine most 780 TIs on clock speed (not memory clock). I’m going to make it my new 780 pin-up!

## ## ## ######## ######## The chip is Samsung k4G20325FD-FC03, I have some. So, will go ahead and see if we can resolve the faulty memory. Proceeding to remove and clean the faulty E1 chip pads as per Graphics Card VRAM Chip Replacement Procedure.
Nice! Replacing the chip, all is well – Driver’s load, MATs passes (10Mb, 25Mb & 50Mb). Actually, things are better than fine, I love this 780! It runs so cool and kicks out a massive core clock 1097Mhz, that’s even higher than it’s stated boost clock!
Have changed all the thermal pads now, was hard to get the thicknesses right.
Under full load, the card seems to be able to stay under 60 degrees C, which is excellent for a GTX 780.
Hi,
I found your wonderful blog, and I thought I’d ask you about this. I found a seller on my local (online) marketplace selling an Nvidia GPU that apparently works well, but restarts the computer under 20 minutes when using the 3D part of the GPU. 2D apparently works forever. The seller tried running MATS, and it shows 33 write errors on FBIOD0, bits from D000 to D031 (that’s only 32 bits…interesting).
It’s for a very good price, and if I could get it working, that would be awesome, because I can’t afford a GPU for the full price. But I don’t want to buy it and then discover it’s a core issue or whatever.
Do you have any clue whatsoever what the 33 write errors and turning off when in 3D for >20 minutes mean? The number “33” seems pretty common.
Hi Matt, thanks for the kind message. Sorry for the late reply, I only just saw your message! 33 errors are thought to be a software issue within MATS, and typically ignored, so it could be misleading. Which type of card is it? I get where you are coming from, it would be great to get a faulty card and fix it. Memory issues are potentially reasonable targets if you are willing to develop hot air type skills, but please see my page on it to first get an idea of the steps if you haven’t done it before https://rupz.me/electronics/graphics-card-vram-chip-replacement-procedure/. In general, buying faulty cards is typically risky, I have a box or so of scrap cards as a result! Let me know if you choose to buy it and maybe I can help you diagnose it.
Thanks so much for your reply!
I got in touch with the seller, and he says it now doesn’t work anymore, shows error 43 in Device Manager, and MATS now shows a much bigger number of write errors on one of the chips (the first one). From what I gathered, this very much seems like a VRAM issue, right? I think I will buy it and give it a shot. 🙂
By the way, it’s an RTX 2080 Super with Samsung chips, not Micron, according to seller). It’s an insane GPU, I’m excited to try fixing it. I only repaired one old GTX 470 (I think that was it) in the past. But I have soldering and hot air skills from other electronics work, so I think I’ll be able to do a reflow/replacement of one chip, especially with your excellent guides.
This blog is an outstanding resource for people like me. All the other guides I found said you need special equipment and whatnot, only yours shows the processes with more basic tools. So thanks again!
Pleasure Matt, thanks for your kind feedback. It helps me, because it encourages me to improve the quality of blog posts (it’s more just a log most of the time), but I like it when it helps people. Please do let me know any improvement points etc.
Wow! sounds nice. You sound like you’re doing well and don’t need my help. I generally hold myself back from 20 series any above (still have a couple of turning cards). It does sound like a VRAM issue and possibly the version of mats he is using isn’t quite right. Error 43 can also be BIOS (sometimes) and sadly also core related. My main suspicion when ebay sellers quote mats is why they didn’t fix it themselves? Do they know something else that they aren’t saying? But probably just me being suspicious. If they sound genuine, my advice is just buy it if you are happy with the price and worse case outcome.
Thanks again!
Such a nice looking card, And those clocks and temps are amazing. Nice work 🙂
Hi Paul, thanks for saying 🙂 I know you’ve upgraded from the broken 780 you kindly sent me, but should you want a 780 for a retro build let me know. This one has been a pleasant surprise, I didn’t know 780s could run so cool, but I am discovering that certain ones can be much better than the reference types. This particular type seems to be sitting at the top of both the 780 and 780 ti boost clock speed ratings table. So, I will look out for iChill type cards of all sorts now 🙂
Hi,
Yeah, the seller seems nice and honest. He said he got the MATS results from a repair shop, but he didn’t need to get it fixed, as he wanted to upgrade anyways. Probably the price they quoted for the repair was too high, and the average computer user isn’t able to do such repairs on his own. That sounds right to me.
Even if I won’t be able to fix it, faulty cards like this one sold on eBay in the past for twice as much as I’m buying it for (I’m not buying it from eBay, but a local eBay equivalent). So if I don’t figure it out, I can just pass it on for the same price. No money wasted 🙂
I’m gonna buy it then. I’ll post here any updates and whether I managed to fix it.
Thank you!
Thanks Matt, it sounds like a sound buy. Best of luck with the repair! Thanks again 🙂
