r9 290 "black screen"
hello i bought a faulty radeon r9 290 (black screen) to learn to fix gpu's, when it arrived i mesured resistances on 3.3 v and 12v both on the pcie connector and cables i have no idea on how to recognize 1.8v pex and 5v but i checked all inductors and none had a dead short only one was 55 or 140 ohms i don't really remember and i assumed it was memory i installed it on the pc and it delivered no image, not even a backlight so i installed it as a secondary graphics card using the igpu as primary, both device manager and gpu-z only showed the igpu so i assumed it was acutally a no detect even tough the monitors tried to turn on when they were plugged in the gpu, i then downloaded flashed mats\mods for my radeon card on an external ssd and while trying to boot into it with the i gpu it delivered black screen, i switched to the r9 and it outputted an image, i didn't run the memory test and went into windows and it ran furmark nicely until it reached 94* and at first black screened then after a reboot started artifacting but kept running, then after another reboot it artifacted on desktop and stopped working, i repasted since it didn't have a hotspot reading so i assumed it woul'd stop working because it had over 100 degree hotspot, after the repaste it stopped detecting i ran a mats test and it passed with no errors (elpida memory ) so i rebooted to windows and started working again i'm now running superposition sterting with 500 mhz clock and incrementing by 100 until and it crashed at 900mhz and started showing artifacts then it started working again for a bit at 1000 mhz and crashed again it seems like a driver crash because when i close the benchmark it goes back to normal but i get a amd error report, i tried to reflash v bios using https://www.techpowerup.com/download/ati-atiflash/ flashing this bios https://www.techpowerup.com/vgabios/...90-4096-131222 but i get mismatch p/n and it fails to flash the vbios, i don't know if my card is the oc version or not. the vram test only has 290x options i don't think that it affects my results, what else can i do?

graphic card showing artifacts may be its problem on chip, with more poin you already test that VRAM is good, problem on chip not always to be dead or no display, sometime artifacts can be occur if thats chip was broke, tell me if im wrong, just saying with my exp
thx -
Its not really artifacts, It only artifacts After crashing, i tried putting RAM clock from 1220 MHz ti 650 and the card crashed i can only get It to 650 mhz if i First lower It but not all the way, Is It a sign of dead Memory controller? Also some days It works more than othersComment

Usually these R9s are too old and the pcb is also degraded to 100 cards, 65 cards open gpu 20 cards vram errors the rest are faults and pcb burns, if u want learning repair graphic card you should buy dead card model begin 750Ti to 1050PC work for schemaltic:
Mainboard: Gigabyte Z68XP-UD4
CPU: I3-3240
Ram: 16Gb
Graphic Card: GTX 1050Ti zotac 4Gb Mini
SSD: 120Gb
HDD: 2Tb

Hello, I got my RTX3080 from DELL. The problem was that in the load appeared artifacts and then BSOD or straight reboot PC.
I tested the memory using MATS and no errors were found. So I assumed it was a cracked solder ball under one of the video memories.
I reflowed the memory, and the card started working. It worked for about 2 days, and then after about 2-3hrs of load, the monitor suddenly shut down, and since then it can't post anymore. Temperatures were normal the whole time.
Is this the definite end for this card?12-17-2023, 06:41 AM -
Hello,
I need help identyfing what is broken on this GPU - GPU core or VRAM. Let's start with what I did and know so far:
- disassembled, added missing SMD capacitors from same GPU
-(If anybody knows what Q518 is and would share this information I would be very grateful)
- artifacts during Windows booting are blue vertical stripes, I can take a photo if that would help
- artifacts in Windows are yellow-ish horizontal lines
- in BIOS/ text on black screen text gets extremely garbled
- GPU-Z doesn't show GPU or VRAM frequency
- GPU error 43... -
Hello (sorry for my bad English),
I have a strange problem with my KVA2 RTX 2060 Super. As soon as Windows 11 is loaded, artifacts appear. Now the crazy thing: When I start Furmark the artifacts are gone and Furmark runs great without crashing. Mats test shows me no errors (PASS). Drivers can also be loaded without any problems.
Mods shows me the following error:
...Code:MODS start: Thu Feb 1 19:16:00 2024 Command Line : gputest.js -oqa -old_gold -test 94 -dramclk_percent 100 -ignore_fatal_errors -run_on_error -fan_speed 70 -matsinfo

First of all, thank you everyone who helps others in here! You guys are treasures! Please bear with me, this may be long. I have tried a LOT.
First, my wife said the TV was turning off and on. When cold it would be fine for several minutes, then it would start resetting.
I opened it up and noted there are two main lines coming out of the supply besides the backlight., The T-Con 12V line and the main 12V line.
TRIED 1 - I scoped power coming from Power Supply while it was all still connected. I noted that just before it reset, the 12V line going to the T-Con was going... -
Hello everyone,
This is my first post on the forum
I recently purchased a MacBook A2141 from a colleague at work, which had issues with the dedicated GPU. The system occasionally displayed artifacts on the screen and sometimes experienced kernel panics related to the GPU. Interestingly, applying pressure to the VRAM module would temporarily resolve the artifact issues, which made me optimistic about the ease of repair.
Board: 020-01700, Config: Intel i7, 512GB SSD, 16GB Ram.
Before completing the purchase, we decided to erase...
