A page to help me track incoming items to work on. Eventually, these will be converted to posts when worked on.
Graphics Cards
- (Hasnt crashed so far) Quadro K2200 4Gb (£10 – Seller Note –
- This was supposedly a working Nvidia Quadro K2200 4GB which I bought from another EBAYER but had problems from the outset. The K2200 is an excellent allrounder and I use them for 3D Design software (CNC). Not for gaming but CADCAM and video editing.
- Symptoms: It boots up and runs fine which is promising but then it can randomly go BSOD or the screen becomes partially garbled on certain applications, it ran hot on GPU-Z. I already use K2200’s in other machines so I can confirm it’s probably faulty not software or drivers issue. I suspect heat damaged.
- I’ve cleaned out the fan and completely blocked cooling ducts plus replaced the thermal paste which has reduced the overall temperature when running but ultimately not fixed the problem. Might be useful for parts or a repair project if you’re in the know.
- Komuster HD passed. Thermals seem fine. Twisting under load seems fine. Might be one of those cards that you can never be fully confident about, could be useful for testing.
- (investigate shorted Vmem rail) Titan Black x2 – £8 each, Seller Note “Dead”
- Yep! They probably are dead! 🙂 Bought out of curiosity, as they are cheap and was interested in the parts as they are a kind of super 7-series card with 6Gb. However, they both have worryingly low VMem rail resistances, so they may be worse scrap than I’d hoped for. Still deserve a proper investigation.
- (repaste and blog) Asus GTX 1080 Strix – £55 “crashes after 5 minutes”
- Actually passes all my benchmarks
- Only issue noticed is that if I twist the card under load, the core temp spikes. This could indicate dry paste perhaps. I also think the center fan rotates a little differently, maybe slightly slower and the pattern in the center appears to wobble slightly.
- Think I will repaste the card and test in my main PC.
- (new fans ordered) RTX 2060 – £55 seller note “broken cooler and fans”
- This appears as described. It can complete basic benchmarks, but obviously gets hot, as the fans are completely seized.
- New fans ordered.
- (occasional blank screens after load, pc still running) Gigabyte RX 5700 XT Gaming OC (Card B) – £50 seller note “random blank screens”
- Seems as described, only one blank and one frozen screen so far, back feels pretty hot under load (probably normal for a 5700 xt)
- Seems fine apart from one blank screen when exiting Kombuster HD, windows 10 was still running in the background and even redisplayed the ‘shutting down screen’, so not a hard crash.
- Subnautica seemed ok for 10 minutes
- 3D Time Spy passed with an average score, heaven benchmark fine.
- Temps seem relatively well behaved <65 core, <89 hot spot, <60 memory
- UVD and VRM temps always read 0 in GPU-Z, not sure if this is normal, can compare with card A
- Should try testing memory
- Seems to basically freeze the benchmark screen on exit, but allow the PC/Windows to run
- (blank screen on flex/load) MSI GeForce GTX 1660 SUPER GAMING X– Seller Note “Around 6 weeks customer returned computer after it blue screened multiple times. I have reinstalled drivers and installed furmark which seemed to run fine but after around 3 hours it crashed again with blue screen. I have replaced the GPU and computer was running fine again”
- Card looks really nice, and runs fine on the desktop for me.
- No crashing, but can blank out and close the application after a few minutes e.g. Kombuster.
- Twisting the card gently also seems to reproduce the issue
- I would guess the seller’s customer mistreated the card and maybe cause a solder joint issue that can impact with heat/flex.
- Should see if I can spot anything in MATS
- (artefacts under stress) Gigabyte RTX 2070 Super Windforce OC 3x 8G – £67 seller note “The card has not been used for a few months, it was starting ok then after a while picture would start corrupting. It would then would stop working at all.”
- Runs benchmarks and games, but soon artefacts
- Need to test with MATS/MODS
- (gets hot, crashes) GTX TITAN X 12GB – £66 Seller Note “Titan gtx has just been serviced I got recovery screen come up easy fix but I had a spare card so grab a bargain only used for fortnight and red dead” – The seller was of course exaggerating the truth! The card works at first, even passing some benchmarks e.g. Kombuster, but gets pretty hot (80+ core, 96+ Hotspot), then crashing starts.
- (move to scrap) PowerColor RX 550 Red Dragon – £8.29, seller Note “Don’t have time to repair it” (long shot, these cards often have dead cores)
- Not very happy with this seller, backplate is missing and fan header is soldered to wires!
- All voltages appear present
- Appears dead, I don’t like this card, but should try to confirm it’s dead
- (serious artefacting, faulty VRAM) EVGA GTX 1060 6Gb SC – £25, Seller Note “Artefacting” (artefacting looks quite light, hopefully VRAM)
- Artefacts appear more serious. Need to try mats/mods
- Found failing A0 VRAM chip
- (missing components, likely 12V short, scrap?) MSI GTX 970 4Gb Gaming (Card E) – £18.93, Seller Note “PC wont switch on” (12V shorts are very common on this model)
- Theres actually multiple missing/damaged components that we’re disclosed
- (hot spot, suspected mosfet fault) EVGA GTX 950 2Gb SC – £13.50, Seller Note “Was used in a media PC. However during testing found that games crash after a short time.”
- Has a ‘hot spot’ that reaches about 100°C+ within a minute or so of load, fairly hot even without load. Suspect it’s a faulty MOSFET, need to investigate.
- (very low 12v PCI resistance) Quadro K5000 4GB – £15, Seller Note “Raw return, faulty”
- has low 12V PCI resistance, practically shorted – need to investigate further
GDDR6 Cards/high-interest
I need to improve my memory testing software before processing these cards.
- Gigabyte RX 5500 8Gb – £43.29 – interesting card, semi-working
- Gigabyte RX 6600 XT 8Gb Eagle – £64.06 – Error 43, has picture.
- PowerColor RX 6700 XT 12Gb HELLHOUND (white) – £124.99 – Lovely looking card, error 43, has picture, still has warranty stickers. If I can’t pinpoint a memory issue, I may resell it.

To Sell
(working) GTX 1080 Sea Hawk X – £120 seller note “Straight out of my current build. Fully working. I do apologize but I didn’t have any compressed air left for blowing out the radiator prior to photos!”
- Seems to be working fine, even without a fan on the radiator, not sure if the owner realized there should be one. Condition seems fine, warranty sticker still intact.
- I really like the Sea Hawk cards, I have a scrap one that I was trying to use reuse the cooler on another standard GTX 1070 board. I am hoping this one can help me confirm a few readings.
(working) NVIDIA Quadro K2000 2GB GDDR5 GPU (Card ?) – £3.93! Seller Note “This came from a system which wouldn’t boot. I don’t have the means to test it so i’m selling it for parts / not working. This might be suitable for anyone who might need a fan or IO shield or is willing to have a go at testing it themselves. Selling it very cheap so someone has the opportunity to give it a go”
- love this attitude! At that price it is purely about reuse, even if it’s unfixable, I’ll still be happy! 🙂 I have fixed several cards of this type, so hopefully this will do as parts in the worst case.
- Resistances
- Vcore – 24.7
- VMem – 204
- PEX – 680
- 5V – 3.22K
- 3.3V – 6.94K
- 12V – 4.5K
- 99p and it seems to work fine, clean condition, great seller! 🙂
(working, no issues) PowerColor RX 590 8Gb Red Devil – £46, Seller Note “Works fine but has noisy fan” (have a donor card, hopefully just fans)
- Appears to work fine und test, fans also seem fine
- Play tested in my main PC, no issues, no noise either
(working) Gigabyte GTX 750 Ti 2GB Low Profile – £15 “Bought on Facebook Marketplace as an unused graphics card that was working years ago. Plugged it in and it popped and smoked and took my motherboard with it as it died. Don’t know if it’s fixable but the heatsink and fan is still working so could be used as a doner part”
- PCB appears fine, no burns that I can see or shorts.
- Passes Kombuster HD, OCCT (mem/3d) and was fine when my daughter played Roblox for an hour or so. The only blips were some blank screens during the GPU-Z render test, possible PCI issue? I would like to repeat the test on another motherboard.
(working) ASUS Turbo GTX 1070 8GB (Card A)– £49.99 Seller Note “This is a graphics card from my old computer, I have not tested if it works or not but it is in good condition. I only used to use it for gaming, not crypto mining or anything that will affect the quality of the graphics card.” – let’s see what shows up 😉
- Seems fine so far in testing, nice! Will play test with it. Apart from selling it, it could help me compare to another similar card.
- Take measurements to help repair the GTX 1070 Sea Hawk
- Changed cooler for the (now scrap) card B’s cooler
- Running well 76°C Core, 86°C Hotspot. Passed 20 rounds 3D Timespy stress 98% frame stability
