Andy van BXBoards heeft wat info over de matige overklokbaarheid van de SL2WM C300A's (dat zijn de als retail verpakte OEM Celery's):
Many of you are still concerned about the SL2WM which is now sold retail boxed. I've been getting a lot of mail reporting that 450 with these chips is a bridge too far. A couple of vendors have also written in with some figures. My own Overclocking Survey results are showing around 60% success with the retail boxed SL2WM. These vendors report odds of around 75% of hitting that 450 sweet spot. I suspect the true figure tends to lie in between the two...
