Newegg doesn't carry Sanmax, and the Kingston (especially if it's KVR) is probably hit or miss.
But.....
let me preface this with the disclaimer that I have no idea if Transcend makes quality pcb's or not.
Having said that here are about four or five ifs that may lead to your disired Mosel chips at Newegg.
From
here you'll see that Asus claims that Transcend Model # TS32MLD64V4F3 and Model # TS64MLD64V4F3 carry Sammy TCCC or Mosel 5B.
256MB Transcend TS32MLD64V4F3 NA SAMSUNG SS K4H560838D-TCCC v v v
512MB Transcend TS64MLD64V4F3 NA SAMSUNG DS K4H560838D-TCCC v v v
512MB Transcend TS64MLD64V4F3 NA SAMSUNG DS K4H560838E-TCCC v v v
256MB Transcend TS32MLD64V4F3 NA Mosel SS V58C2256804SAT5B v v v
512MB Transcend TS64MLD64V4F3 NA Mosel DS V58C2256804SAT5B v v v
And from
here (256) and
here (512) you'll see Newegg is claiming to sell Transcend modules with the correct model numbers.
So your best bet is to call or email Transcend and ask exactly what chips they have used on the TS32MLD64V4F3 and TS64MLD64V4F3 models.
Depending on thier answer you may be able to narrow your chip error margin. If (last if) I remmember correctly those Sammies are said to be pretty darn good also.
