Usually laser crossed chips are rejects that didn't meet quality standards, the other thing to note is that the ICs on that card look to have been replaced, I suspect that perhaps the original ram died and they replaced it with el cheapo reject ICs from China. (This is not an accusation against the seller, it might be they got it like this themselves)
You can even see the dodgy soldering on the lower IC just below the C294 cap which itself looks like it got a bit too much heat and moved slightly. (It looks like two of the legs on that lower IC are shorted by a bit of solder)
ICs get rejected for a myriad of reasons and they may or may not be perfectly ok to use but they come with exactly zero guarantee of fitness for purpose or longevity which is why they are so cheap and China has a metric ton of them laying around . .usually you find them in $2 2tb USB drives.
