Here is a list of graphics cards to be used as spare parts.
- GIGABYTE NVIDIA GTX 1060 3Gb (Card B) (Hope it’s as good as the other one I had! 🙂 Erm.. sadly not, it’s shorted VRM phase has damaged the PCB! – think it might be too much effort to repair, nice for spare parts hopefully, even fan and box could be used directly on my other identical 1060 )
- EVGA GTX 780 2Gb SC (Card B) (had short on memory rail – dead core)
- EVGA GTX 780 TI (SCRAP grade A – could replace core, no shorts, resistances looked ok, blank screen, main voltage rails appeared to be there vcore & vmem – if detected, could try mats – not detected)
- Sapphire Pulse 5600 XT (SCRAP salvage minor components only – Listed as ‘not detected’- interesting card! Sadly multiple shorted rails, with the core being the source)
- NVIDIA 745 OEM (likely GPU replacement needed – cannot get replacement GPU, out of stock)
- MSI 710 1Gb – Card D (actually has bad component damage near the HDMI port, beyond reasonable repair)
- MSI GTX 1070 (listed as ‘I’m not sure if Ti version or not. The sticker has been removed. I got it as untested but found that it didn’t work. Cosmetically looks fine but will likely need professional repair’ – was relatively cheap, hoping a) it’s easily fixable b) the ti version! – resistances ok, has main voltage rails, not detected, need to analyse further – gpu is dead 5 ohm pex, refclk-+ 0 ohms, reset 0 ohms, so not ti version and not fixable without new gpu)
- ASUS GTX 750 Ti OC 2GB (SCRAP grade B – Free card, core physically damaged, not detected, all voltages, resistances OK)
Donor Boards and Noted Parts
I want to start reusing more parts, as my collection of donor boards is increasing.
MSI RX590 ARMOR 8G – Unfixable. Expect core dead. Hopefully OK VRAM
- VRAM – Hopefully OK Hynix H5GC8H24AJR-R2C
- 5V regulator – APL1117
- 1.8V Buck Converter – GStek GS7166
- Display Rail Buck Converter – GStek GS9238
Scrap Components
FDMF 3035 – Scrap RX470 (thought to be an RX470, unconfirmed) – condition bad overall
Lenovo GTX 1070 8Gb (suspected dead core, low PEX 7.6 Ohms)
- Resistances all seem fine apart from PEX, 12V rails high ohms, 5V, 1.8V normal resistances
- Good VRAM resistance 38 Ohms
- Useful parts for reference type GTX1070/1080
- Dual MOSFETs 4C85N
- VMem PWM Richtek 7J= https://www.richtek.com/assets/product_file/RT8816A/DS8816A-07.pdf
