This page is to feature all the Polaris GPUs I have worked on.
What is there to like about repairing Polaris cards?
- Well trodden ground i.e. well analysed by repairers, like this excellent guide https://repair.wiki/w/AMD_Polaris_GPU_Diagnosing_Guide
- they are very popular, lots on the market.
- Still quite fun for HD gaming
- As AMD/Radeon cards go, most Polaris cards can use tserver to narrow their very common memory issues
What is there not to like about repairing Polaris cards?
- BGA issues – Due to their often generous memory (8Gb) and reasonable price point, they have often been a popular choice for miners. As such, they can suffer from thrashed memory and worse, memory controllers, making some unfixable for many people.
- These cards feature I2C PWM controllers, which can be challenging in that reprogramming may be required.
RX 460
- Gigabyte RX 460 2Gb (no power to card, fuse issue & likely vrm short)
RX 470
- Asus ROG Strix RX-470 4GB (lovely condition, runs, but seems to get hot. Seller said it can fail)
RX 480
- Sapphire RX 480 4Gb Nitro+ (12V short, unreadable BIOS)
- MSI RX 480 GAMING X 8 GB (Error 43, crazy sensor readings in GPU-Z! Possible BIOS issue suspected)
- ASUS DUAL RX 480 OC 8GB (Error 43, crazy sensor readings in GPU-Z! Possible BIOS issue suspected)
- Sapphire RX 480 8Gb (Bad burn behind VCore VRM phase and short, hard repair, probably spares)
- XFX RS RX 480 Double Edition 4 GB (Error 43, picture on display port next to HDMI, A channel artefacts)
RX 560
- XFX RX 560 Double Dissipation OC 4 GB (SCRAP Low Grade, components only – Shorted, needs more checks, but probably scrap. Much worse on closer inspection, corrosion etc)
RX 570
- MSI RX 570 ARMOR OC 8 GB (error 43, need to test and measure)
- SAPPHIRE NITRO+ Radeon RX 570 4GB (SUSPECTED FAULTY CORE – detected, blank screen, crashes on driver load)
ASUS ROG Strix
- ASUS ROG Strix RX 570 8Gb Gaming OC (Card A)(suspected VRAM issue / error 43)
- ASUS ROG Strix RX 570 8Gb Gaming (Card B) (BIOS is not readable, signs of previous repair)
- ASUS ROG Strix RX 570 4Gb Gaming (SCRAP – Sold as dead core, it is popcorned, Vmem rail short which is hopefully from the core, otherwise hopefully useful spares)
XFX Black Edition
- XFX RX 570 4Gb Black Edition (FIXED – BIOS replacement, both)
- XFX RX 570 4Gb Black Edition (Card B) (FIXED – Faulty VRAM channel A, error 43, vertical bar artefacts)
- XFX RX 570 4Gb Black Edition (Card C) (Vcore, Vmem, VDCI, Display rail, BIOS Switch all missing, signs of previous repair attempt – may still be fixable, but more of a ‘long shot’ compared to other cards I have)
RX 580
For me, the RX 580 is a classic card! There are a lot of varieties, this is my favourite that I have worked on:

- MSI RX 580 8Gb Armor (Low resistance on 5V rail)
- Asus Dual RX580 8Gb (Missing VDCI, VMem, VCore)
- PowerColor Red Devil RX 580 OC (Intermittent voltages and detection)
- Sapphire NITRO+ RX 580 8Gb Special Edition (FIXED/IN TEST/FAILED AGAIN! – Initially feared a dead core, but luckily it seems to be only a faulty PEX reset logic gate – now not detected/no fan spin)
- XFX RX580 8Gb (Card A) (FIXED, MORE TESTING, VRAM replaced, 5V LDO replaced, need to test, possible VRM efficiency issue)
- XFX RX580 8Gb (Card B) (FIXED Gets to windows, possible heat problems, missing VRM screws, needs clean, repaste and retest)
- XFX RX580 8Gb GTS XXX (Card C) (WORKING, MORE TESTING Seemingly OK, needs more stress testing, missing screws)
- XFX RX 580 GTS XXX 4GB (WORKING reported as faulty, under test)
- SAPPHIRE RX 580 4Gb NITRO+ (F, Had corrosion, needed new thermal pads, BIOS issues)
- GIGABYTE AMD Radeon RX 580 8GB (Missing VMem, VCore)
- ASUS ROG Strix RX 580 8Gb (Seller Note ‘Not working correctly – lines are displayed on the screen as per the photo’ – does have this problem, tserver reveals failing A0 chip)
- ASUS ROG Strix RX 580 8GB (Has a damaged ITE 8915FN-56, hopefully, this is all and can be replaced, nice looking card)
RX 590
These cards are great! They will play 1440p quite well. Juicier, but have more powerful core performance than 580s.
- XFX RX 590 8Gb Fat Boy (FIXED – Had a faulty 5v regulator, but seems to work very well after replacement)
- XFX RX 590 8GB Fat Boy (Card B) (Vram issues, ripped pads)
- PowerColor RX 590 Card A (All voltages, no picture, not detected)
- MSI RX590 ARMOR 8G (SCRAP – Short, PCB damage, not easily fixable)
