Re: Gigabyte Aorus 1080ti - card not initialising #2
What kind of 800w hot plate did you use? Feel free to post more picture of the setup showing the thermocouplesLeave a comment:

Re: Gigabyte Aorus 1080ti - card not initialising #2
Sounds great and even more helpful the level of details. Thanks for continuing to update....Leave a comment:

Re: Gigabyte Aorus 1080ti - card not initialising #2
So it increased from 28917? Still wrote only errors? Same bits or different ones ? So you have the equipment to reball the GPU ?...Leave a comment:

Re: Gigabyte Aorus 1080ti - card not initialising #2
If you don't mind measuring their resistance before installing it would be awesome...Leave a comment:

Re: Gigabyte Aorus 1080ti - card not initialising #2
Perhaps you could run MATS with the memory locations empty to confirm the error counts climbs up. I have seen reports in various discord chats of error counts staying the same even with memory chips removed thus confirming in those cases that the problems are with the GPU built-in memory controller instead of the memory chips (although in your case it sure looks like memory chips based on your findings of the measures of resistance of vMEM (FBVDDQ))Leave a comment:

Re: Gigabyte Aorus 1080ti - card not initialising #2
You seem to be on to something here
Copying from the other thread and adding the new info:
Two supposedly new GDDR5X Chips Micron code D9VRL date code 8MA77
The resistance of A1 to B1 measures:
20.6 K ohms
19.5 K ohms
The resistance of A2 to B2 measures:
50 ohms
47 ohmsLeave a comment:

Re: Gigabyte Aorus 1080ti - card not initialising #2
Even one of the chips that had the higher resistance did not make a difference?...Leave a comment:

Re: Gigabyte Aorus 1080ti - card not initialising
Of note, it is mentioned that in 2018 Micron had many bad batch of GDDR6 memory (different then GDDR5x used in the 1080 ti). Supposedly anything older than date code 8Y is bad. I have no other information at this point.
Of course this is the different memory type GDDR6 that is probably unrelated. D9WCW BGA code.Leave a comment:

Re: Gigabyte Aorus 1080ti - card not initialising
This means my "new chips" were made in 2018 in the 26 week of the year.Leave a comment:

Re: Gigabyte Aorus 1080ti - card not initialising
According to "CSN-11: Product Marks/Product and Packaging Labels Introduction" from micron on page 6
Date codes are alphanumeric characters that indicate the year and workweek the parts
were marked, in even-numbered workweeks. The first characteris the last numberin the
year, and the second (alpha) character is the workweek.
A = 2 E = 10 I = 18 M = 26 Q = 34 U = 42 Y = 50
B = 4 F = 12 J = 20 N = 28 R = 36 V = 44 Z = 52
C = 6 G = 14 K = 22 0 = 30 S = 38 W = 46

Re: Gigabyte Aorus 1080ti - card not initialising #2
Can you please measure the resistance on that chip prior to reball and mention the data code on the chip ? The more data the more we will be able to re-use parts and also not get sold used parts as new....Leave a comment:

Re: Gigabyte Aorus 1080ti - card not initialising
As a data point I have two supposedly new GDDR5X Chips here Micron code D9VRL
Their resistance of 1A to 1B measures:
20.6 K ohms date code 8MA77 (KJF4)
19.5 K ohms date code 8MA77 (K7C9)Leave a comment:

Re: Gigabyte Aorus 1080ti - card not initialising
It would be interesting to find out if there is a specific bad date code on the memory chips that went bad or a specific location they were on the pcb.Leave a comment:

Re: Gigabyte Aorus 1080ti - card not initialising
I have the same card with the same low resistance on vmem. I have not yet removed the memory but your test sure makes it look like it is worth to try! Thanks !!...Leave a comment:
