Hi, so I just got my Asus 7900 XT with 20 GB of memory and I installed it and it seemed to be running fine until I noticed that about every 2 minutes or so while in game I would get a lagspike lasting maybe 0.5 sec then it would be all fine again for another 2 minutes.
After checking afterburner I found that it looks like the memory is slowly increasing in usage (see image) and then suddenly dropping off and when that drop happens I get the lagspike, no matter what game I play. I've reinstalled the drivers with DDU etc but nothing works.

Also, it looks like it tops out in afterburner but the actual memory used still goes up to around 8.7k Mhz then drops 1000 Mhz down to around 7500 Mhz and starts the climb again.
