Sparkle

Sparkle is using the reference NVIDIA HSF, which in this case, wins a great deal of points. The NVIDIA reference cooling solution has rubber nubs around all four corners of the HSF solution. This adds stability to the part that many other cards in this review lack. Unfortunately, the spring tension isn't wonderfully high, so cooling is a little lower than what might be desired. The spacers may add stability, but they also make it so that in order to get really good contact for cooling, the part would need to be pressed down harder than it currently is.

There were a couple of vendors who sent us "press samples" that were clocked at non-shipping clock speeds. Sparkle is included in this group, but we've asked them to only send us products that we can buy on the shelves. The part that we have in our labs boots up at 507/550, but we clocked it higher than that, easily.

You have to wonder who made the decision that seven MHz and a tiny bit of memory bandwidth was really worth sending us a press sample when we asked them not to do so. Because of that, we also can't be sure that the components that went into the part weren't binned beforehand - the 2ns DDR3 memory easily hit 610MHz.

Getting 2ns memory to clock that high is obviously not impossible. It can happen by chance (we've seen it before on earlier parts that used it), but we'd rather have no doubts.

At the same time, we asked for shipping parts and this is what we received. We'll report all the information that we have along with the numbers that we get and let the readers make the call.
