I smell a scam. Care to post some pictures of the dimms as well as a close up of the markings on the chips.

Alll DDR2 is 240pin BGA (ball grid array) Very different to DDR1.

how much did you pay for them? what model/brand are the supposed to be?

Wrong! there is 92 balls and 60 balls DDR2 ram chips but none is 240 pins.
BGA is recommended in JEDEC spec but it is not required. Some chip manufcaturers do have TSOP packaged DDR2 chips that are mainly for low speed <533MHZ operation to cut down the cost.

The DIMM's pin count is a better indicator of whether the module is DDR2.

RMA them to Corsair and you'll find out.

If it works, then it's DDR2. My Mushkin DDR gives me bogus and serial number info in CPU-Z and it's real (verified by a Mushkin employee who said, "that's actually good stuff").

RMA? Corsair? wtf?? I got them on ebay. (and for only $157 too).

So anyway, I guess if you guys say the DDR2 is good without FBGA chips then I'm a happy camper.

I've been using them and it's been a HUGE improvement in performance. I went from 1 stick of 512MB PC3200 (single channel). To these two 1gb sticks of PC5300 (dual channel). The bandwidth is nearly quadrupled.

It works and it works great, so I really can't complain. I'm really just surprised about it more than anything.

Isn't PC3200 DDR, not DDR2? What mobo do you have that takes both?

There's PC3200 DDR2 too.
