This is the best that I can do right now.
Here is what I received.
I just opened the box and all I can tell you is that I got the best I could have hoped for. The link below is to a post in Extreme but the markings on the heat spreader (product ID, description, etc) are EXACTLY what is on the KHX PC3000 that I got in my shipment from ZZF. In addition, I counted the legs on my chips and they have 33 on each side which means that it is NOT the remarked Kingston chips which has something like 54. The stuff I got is OLD stock, it even has a label stuck on it with "Googlegear" (the old name for ZZF).
Without having tested it and it will be days before I get a chance, I can not guarantee it, but I am 99.9% sure that it is original Winbond BH-5 at $220 for a gig (2 x 512). It was $215 when I ordered it last week.
FYI - It is $260 now at Kingston (mostly remarked chips from what I can gather from reading the posts at Extreme) and Newegg is out of stock of the 512s, but has 256 modules (don't know what they are shipping).
Again, these pictures are not of my ram, but as I said, the markings on what I got are exactly the same all the way, everyway.
This is what I ordered:

And these are the same MARKINGS ON THE HEAT SPREADERS as the ram I received. This is NOT my ram. Please understand what I am saying here. In the posts at Extreme, there were pictures of several different KHX PC3000 modules with different markings, however, all of the ones that matched what I got had BH-5 when the H/S were removed. The picture is on page #4, at post #5 of the thread on chip markings from Kingston.

I hope that this helps and I'll follow up with more info after I have tested this stuff.
Thursday a.m.
I just checked at Kingston and now they don't even list the PC3000 as a product choice, yesterday it was at $260. They had a big time sale going on recently with it as low as $184 for a 2 x 512 kit (these are the remarked chips I referenced above) so I wonder is they liquidated their stock. If so, that just makes this look even more interesting. I do believe that I have also seen it at Directron.com, but the old stock is drying up fast.
The way I figure, for $220/gig even if it only does 210-220 at fast timings I would be a very happy camper. Wish me luck, although I'm feeling pretty hopeful, right now.
