Hmm I don't think you need an 8,000 kit. Reason being the IC's on this SKU are identical to the ones on the 8,000 modules as in even the bin etc. As is right now, many of the IC's that are 8,000+ capable are ending up in the lower binned sets purely because there's 10X the market for 7200 than there is for 8,000 if not more. So Vendors such as Kingston are actually sticking a ton of capable IC's on low speed SKUs. I can almost guarantee you the 7200 you have is minimum 8400 capable @ 1.5V
