I checked and couldn't find it listed previously.

Corsair XMS:
Model no.: CMX1024-3200C2PRO
Revision: XMS3202 v1.4
Lot code: 0608176-1
This is Infineon B-5/Infineon -5 Rev B/Infineon BE-5. It was listed under a different name than what I was looking for, and apparently this particular version/revision number only shows up as a kit rather than just a single stick.

The RAM in question:
VS2GBKIT400C3 (2x VS1GB400C3 sticks)
Date code/Lot code: 09510073
numbers on IC: PRB0900950

I don't know why, but I seem to have had really good luck with these VS sticks that were made in 2009. So far had three sticks from that year, and all of them run great at high clock speeds without having to change the RAM divider or loosen the timings, a slight voltage bump may be necessary to keep them stable at speeds above DDR478-480 though.

If you see these sticks, buy them, if they perform anything like the ones I've found you'll be very happy with the results.
I do believe I've found a diamond in the rough with these sticks. All signs point to Samsung TCCD IC's, and everyone I've spoken to on the matter seemed to think that was what they were based upon the way they behave and perform (and that is the conclusion I come to as well as they behave nearly identically to some sets of verified TCCD I own). Awesome sticks, they will run at PC3200-4000 with 2.5-3-3-5 1T timings with little or no voltage increase (I ran them at probably 2.7V max at these settings), and need only 2.6-2.7V to hit DDR500 with 2.5-3-3-5 1T timings.

They may in fact run at even tighter timings (possibly with increased voltage), but I haven't tried to go with anything tighter than I've already tried yet.

Actually, finding out that they would run at 2.5-3-3-5 1T was an accident. I had swapped out a set of TCCD I had manually configured the settings for in my bios, but forgot to reset the values prior to switching sticks, to my surprise the system booted up with those settings with the VS sticks and it runs just fine with those settings. Had it up and running overnight and it was still running normally the next morning.
