Artefacting / locking R7 370 - bad memory chip identification

02-10-2022, 10:36 AM

Hello everyone.

My son came to me one day saying that his pc locks up.
I found his onboard sound and gpu not working.

The gpu is an R7 370 and it has weird colors in bios and locks hard when windows/linux loads a driver for it.

I have run a diagnostic utility (a linux based app with mats/mods for nvidia and tserver/memfa for AMD) and it spew out some things.

It says error on ch7 rank 0 bit 14.
Now, i have no idea which of the 8 chips is ch7.
There are 4 chips arranged vertically to the right of the gpu and 4 horizontally on the top

I can try reflowing/reballing as i have access to some equipment but have no idea which memory chip it is.

I know that it might be a bad solder pad on the gpu and not the memory but i have to start somewhere.

Re: Artefacting / locking R7 370 - bad memory chip identification

The memory channels usually go anti clockwise from the bottom right of the GPU, so I guess its the top left memory chip, and probably a cold joint or broken pad since it is only 1 bit failing.

ASRock B650M PRO RS - BIOS CHIP 25Q256JW BLOCKED BY STATUS REGISTERS

by DynaxSC

Hi

I have a very strange issue with the BIOS SPI chip of an ASRock B650M PRO RS motherboard.
The SPI chip is an Winbond 25Q256JWEQ model (1V8).
The motherbaord doas not POST - it lits only CPU and DRAM EZ Debug Leds, and stays that way forever.
The Flashback function of the motherbaord is also not working, despite all instructions followed correctly - I'm 100% sure of this.

I have then desoldered the chip, backupped the contents, and tried to earease the chip in order to program stock image, but the chip is locked by status registers SREG2 (TB) and SREG6...

Guide to transplant MEC1503 EC chip and EEPROM reprogamming for T14s gen 2 and X13 gen 2

by acedogblast

This is a guide that I am writing for helping others to replace their MEC1503 EC chip if it breaks (or to get around an inconvenient prompt to the BIOS). This forum has been extremely helpful to me so I would like to contribute to help others. I will tell you right now that this task is very difficult to do. You MUST have experience and tools to do precision micro-soldering, BGA reballing, trace repair, and general laptop repair skills.

There are some specialty tools needed to do this task. The replacement MEC1503 chips can be acquired from Aliexpress. Do not buy the bare chips as...

NVIDIA GPU Memory Chip ID and Replacement

by shovenose

I'm trying to repair a GTX Titan X, seems to have a bad memory chip. I have this random graphic I found online but my card is double sided, does that matter? And based on the test result, which one do I need to swap?

I am using a Tesla M40 12GB as a donor board, model number of memory chips on that one is really hard to read but I think they are the same.

As for actually swapping a memory chip from the donor board, I have never done any BGA work before. I watched this video https://www.youtube.com/watch?v=goViV2IYogk and it seems he is using a new memory chip, vs...

memory mod for amd radeon r7 260x

by kokodin

Hello, for almost a year i been trying to make something that seems impossible, or my testing software is lying to me and it works only i can't see that.
I been trying to mod a memory on radeon hd7790 or 260x from 2 to 4 gb, but it doesn't seems to be as simple as i first thought.
In theory 2 workstation graphic cards using the same graphical processor have 4gb of memory firepro w4300 has 4 256x32b layout and W5100 has 8x 128x16b layout all use gddr5 memory and internals of the bioses seems to be very similar so i was trying to wing it , but so far it seems either tserver can't show...
