Heat spreader coming off OCZ RAM

Hi, I have a 1GB kit of PC4200 OCZ Performance RAM and the heat spreader is beginning to come off on one stick: when I squeeze both sides of the stick and letting go I hear a click which is the thermal tape losing contact with the chips. Also, I can see a gap between one of the copper heat spreaders (the chips is made out of two heat spreaders held together by a clip) and the chips.
I wouldn't have worried about something like this hadn't I been experiencing system instability which is typical to faulty RAM: Processes crash on me with an error, mostly "explorer.exe" when browsing files (and especially when generating thumbnails).
Taking off the heat spreaders in order to apply some AS5 and tighten the clip means voiding the warranty which is very good IMO (you can OC as much as you want but as long as you don't bump VDIMM higher than 2.9, they'll fix it when it gets broke).
OCZ's support said that they'd replace the sticks but that the instability is prolly not related the RAM.
I just wanted to know if anyone has experienced anything like this and if there is a way fixing it (like adding another clip somewhere?) without sending it back to OCZ since I don't live anywhere near the US :[ .
