MP 6,1 System slowdown due to failing ECC memory?

[th0masp]

Hi all,

Yesterday out of the blue my Trashcan started to act weird: laggy in applications, downright unbearable in the browser and even disc access on the internal NVMe was choppy. No errors in the console as far as I could make out and activity monitor didn't show any processes that were running wild either. A restart didn't fix it.

By accident I stumbled over the memory diagnostics in 'About this Mac' and it showed three out of four RAM sticks with errors, one had reported like 90000 errors.
I've now replaced the 16GB DIMM's in there with a set of 4GB 🙄 modules the machine originally shipped with and lo and behold the computer seems back to normal.

Just wondering if its plausible that failing ECC memory can be the sole culprit here. No application crashes, no error pop-ups, no ruined files (so far anyway) - just everything behaving like somebody had just pulled the handbrake.

So, you ever replaced the original memory with a higher capacity set? Sure those were compatible?
The last time I did something like that, I left some of the original memory in place,
with the idea that any repair people could not blame the additional memory for any problem.
Fortunately newer machines have been soldered ...
;JOOP!

Pretty sure - the were sold as specifically compatible with this machine and also they've been working in the machine for like six years now. Until very recently, it appears. Never seen such a stutter before.
