Seller Note “Artefacts”
Summary
- Resistances
- VCore – 4.8
- VMem – 114.4
- PEX – 315.4
- 5V – 1.249K
- 3.3V – 613.7
- 12V – 6K++
- Picture, but artefacts even in the BIOS screen
- MATS fails, not sure, but I would imagine there is a chance of a more complex problem e.g. core BGA or memory controller (issues showing across multiple chips)
- The microscope reveals (see the picture of the area near VRAM chip C0 below, flux residue, melted solder on a resistor) what looks to me like previous reflow attempts (I will note this seller, as I saw them sell other cards that sounded like unfinished business!)
mats version 367.38. Testing GM204 with 50 MB of memory starting with 0 MB.

## ## ## ######## ######## Here we can see traces of previous a previous repair attempts (flux residue, a resistor with melted solder at one end). All the work seems to be around C0, although C1 could have also been worked on e.g. reflowed.
I think I have 3 Hynix H5GQ4H24MFR-R2C chips in stock, but I wouldn’t be surprised if this is more core related. I actually have another identical card (TODO add link to Card B), which could do with a few minor components from this card, so I need to decide if this one is fixable really.
Next Steps
- Try removing C0, measure data line resistances for the failing bits from the MATS report
- If there the resistances indicate an issue under the core, then stop for now.
- If the resistances appear normal, try replacing C0 with a new chip and see if there is an improvement in MATS
After removing the chip C0 and cleaning, the pads appear fine. However, the resistances of several dataline pads seem either OL or abnormal, suggesting a possible core BGA issue, trace issue or otherwise faulty core.
Capacitor C79 also needs replacing (dislodged whilst cleaning the memory pads). I think my immediate plan will be to try using some of the components to attempt repair of ASUS STRIX GTX 980 DirectCU II OC (Card B). Down the line, I might also use the card for core reball practice.
