  1. I have some more sticks I'd like to find more information about. Model number: CMX1024-3200C2 Revision: XMS3202 v1.2 Lot code: 0528016-11 Model number: CMX1024-3200C2 Revision: XMS3202 v2.2 Lot code: 0603181-0
  2. 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. 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.
  3. Yeah, you already told me that once. Really I'm looking for answers from someone who knows more about the behavior of memory and how certain IC's perform. Those VS sticks run at DDR500 with timings of 2.5-3-3-7-2T with stock voltage. Now, is there anyone here that has anything helpful to contribute on the subject other than "Value Select modules are built with RAMs that are procured at the wafer level and are packaged and tested to our specifications. As such, they are not available as individual ICs, only as modules. This approach allows us to ship product with very good performance characteristics, low product cost, and a very low return rate." (which by the way is just a bunch of overly generalized marketing jargon, and says nothing about the chips themselves)? Also, you completely missed the stick of CMX1024-3200C2Pro I asked about.
  4. Any ideas as to what IC's these sticks have based upon the information given and/or my results with the Value Select kit and/or my XMS stick?
  5. From what I hear it's determined by what's popular and/or in stock at any given time.
  6. I've now also gotten them to run at timings of 2.5-3-3-7 at the default 200MHz/DDR400 speed without any voltage bump, and they may be able to achieve lower timings than that, but that is one of the only ones I tried that worked. The only other timings I tried were 2-3-2-6, the default for a stick of CMX1024-3200C2PRO I have here, the VS module didn't like those timings at all though and defaulted to 100MHz at 2.5-2-2-6 (or something like that). Seems like very versatile memory for both systems which perform well at high clock speeds and lower latencies.
  7. I don't know what IC these sticks use, but they are far from "Value Memory." Mine got up to DDR500/PC4000 speeds at the default 3-3-3-8 timings and 2.7 volts. 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.
  8. Well, considering Corsair themselves have not specified what that stick actually uses, or what any of the other ones I've asked about use, I was forced to look it up on my own. I'll take an educated guess and/or some other website's word over having no information at all.
  9. This is supposedly Winbond BH-6 according to some other websites I have looked at.
  10. I've got some more sticks here I'm trying to find info on. CMX512-3200C2PT (shows up as CMX512-3200C2 in CPU-Z)/XMS3202v1.1/0304056 (SPD timings of 2.5-3-3-8 at 200MHz with 2.5v) CMX512-3200C2PT/XMS3202v5.2/0530088-0 (part of a 1GB kit) No idea, but I'm assuming Promos -5 Rev A, since all the others found on the list that were from that year seem to have those IC's. CMX512-3200C2PT/XMS3202v5.2/0602111-0
  11. Got another one. Model no.: CMX512-3200C2 Revision: XMS3202 v1.5 Lot code: 0521077-0
  12. Got another one I'm trying to find out more about. I checked and couldn't find it listed previously. Corsair XMS: Model no.: CMX1024-3200C2PRO Revision: XMS3202 v1.4 Lot code: 0608176-1
  13. Today I discovered that some VS modules also use Hynix D43 IC's on a BrainPower PCB, as I bought one recently and to my surprise it had them on it. Strange, in all of my research on this I had never heard of any cases of people finding Value Select RAM with Hynix D43 chips.
  14. Okay, I finally managed to find out that the Value Select memory I have generally uses either Micron -B5 D or Samsung UCCC IC's. I've read that the stick of XMS I have supposedly uses Infineon B-5 IC's.
  15. Almost 2 weeks now and no helpful replies, I'm guessing no one knows?
