Promos, Micron, Corsair!? How do I know what is what?

post #1 of 12
Thread Starter 
Basically my question is what it in the title. After hearing all this talk about Corsair using lower quality memory chips, I am wanting to find out what is in my RAM. However, I dont want to remove the HS. Any ideas as to how to do this?

The 'good' corsair RAM is the stuff that uses the chips with 'Winbond' on them, but yes the HUEG heatsinks (that dont ever want to seem to come off) corsair has on their RAM does prevent you from seeing that. I believe you just pray to the gods of random access memory and hope you got some good RAM ?

It has been found that version 1.x are Microns and version 2.x are the lower quality chips that they change to along the sales process.

Look to your strips and see what version you have. By your components I can certainly understand how you expected to get higher quality dram. What Corsair is doing is starting a model and inserting very high quality Micron DRAM. Then once people begin to rave about its quality and ability to overclock well, they (in the middle of the fabrication week) change the chips from high quality micron to far lesser quality while retaining the prices. They do change the version numbers from 1.xx to 2.xx and now that we know that, we can tell and not buy the lesser quality ram.

It's not that this lesser quality ram is necessarily bad ram. It is that they are selling it at the same prices as the higher quality ram.

Like Ropey said, look at the ver#. If it's 1.x, it's micron and should oc like a monster on crack. 2.x, 5.x, or 6.x, then it's Infineon or Promos or something else, and will not oc as well.

I think 2.x seems to always be Promos. 5.x or 6.x is Infineon or some other stuff.

v2.1, obviously I am not going to complain, as they seem to be running fine so far, and they were free. However, it upsets me that Corsair would do something like that to their customers.

Yeah Roscoe and Ropey ftw. A lot of angry people with Corsair right now, myself included. I got the PROMOS stuff and well, check the second link in my sig to see how the memtest went.

Just like the Corsair rep says, "frequently" some PROMOS run good but in my case, mine were not in the "frequently" category, but more like never.

I will say though, the PROMOS in my XMS2 675s are pretty good, sure I don't hit 1000mhz with them but they went from 333mhz all the way up to 442mhz, a 109mhz OC? not bad, considering they were $150 for the 2GB kit.

I also found out my new dominators were revision 2.1 and not 1.1 (the only model with micron). The sticker will show the revision. I called the supplier today intending to return them and pick up C5 8500's. While I had them on the phone *****ing (me to them), the sales rep (who clearly knew very little) stated that as far as he knew all corsair c4 kits use micron d9s. Wrong. I did get him to go and look at the other dominator kits he had in stock (9 or 10 pieces) and had him look at the revision numbers). Lo and behold he found a set with a 1.1 revsion! I have them on hold and they are going to exchange them for me tomorrow with no issues or restocks (I buy a "lot" of stuff from them under my dealer account). So lesson learned. I'll get the ram I expected by only by luck.
