Did I damage my video Ram? 7950 reference in cf 1100/1600

Both cards are watercooled with a universal block and stock heat plate and reference fan for vrm cooling. Was mining at 910/1600@.975 for a while and mostly playing games at 1100/1600. Here recently I've started having display driver crashes and recovers. Could not figure it out. Gpu clocks did not matter. I lowered my memory clocks to 1350 and the crashes went away. I've been running 1100/1600@1.145 for a few months with no problems and now this. A sign of problems ahead? Full load temps on gpu never exceed 45 celsius and vrm's are usually in the 70 's.. video memory is Hynix..

Might have something to do with flash and UVD clocks. If I run my card at 1500 memory clock, I can't do anything flash related. I can game or bench for hours without any issues what so ever.

Example:

1500 memory clock, load a youtube video = Memory clock drops back to 1250, and if I'm lucky doesn't scramble the screen. More often than not my primary display scrambles and I have to manually restart.

Leaving memory clocks stock eliminates the problem.

It only does it in games. Never had this problem till recently.

Only in games? Ouch. Well in that case, I would start with wiping the old drivers and installing them fresh.

Although, it could just be your memory was unstable all along. I don't mine, but from what I understand mining doesn't really need or use a lot of memory / mem clock speed anyways. So it could have ran fine, but it was never under a heavy workload to cause anything to fail.

Also, do you have any sinks on the ram?

Just the stock heat plate with the thermal pads. I've already tried reinstalling drivers. I've even reformatted my ssd. It makes me wonder if I possibly damaged my card when installed the second water block. At that time I swapped my second card into the top slot and primary card into the second slot. That's mainly when this started. Perhaps that could be the issue? I don't know. I can run stable at 1200/1400 @ 1225 now but stick to 1100/1350@1145. Atleast I don't get the stupid driver crashes anymore. I don't mine anymore as its not worth it now.
