Hi,

Recently I went down the ATI Radeon 9550 artifact repair hole (for the 11th time 😀 ). Currently I am in the process of swapping memory chips for (hopefully) working ones in hopes of removing the artifacting.

Now, I got curious as to what memory chips like to fail often, and which live the longest (since these series only have RAM issues unlike the R9700 which had core BGA issues iirc(or was that R9800?)).

Currently, out of the 3 R9600/R95x0 cards I own:
Two are artifacting, one with Samsung K4D551638D-TC, one with Elixir N2D512H16CT-51B.
One is currently working fine with Hynix RAM (can't write down the model yet 🙁 )

Since the two artifacting ones were mangled by me during repairs, I can't experiment with hynix RAM (due to there being more faults than before which may potentially screw up my results). And I can't be fully sure that hynix RAM lasts longer than the other two.

What are your experiences with these cards? Did you have similar experiences to mine? Did you ever try to replace the RAM for other model? If so, was it successful?
