  • Remove the EMI shield from the logic board, and presto!

  • This board is markedly different than the pre-production board we uncovered.

  • Markings on the A4:

  • N26CGM0T 1007 APL0398 33950084 YNL184A2 1004 K4X2G643GE

  • Yes, the K4X2 is a Samsung DRAM part number!

  • Decoding the part number shows there is 2Gb of memory inside. This translates into ~128MB of memory per die, for 256 MB total. (NOT 512MB, as we previously reported.)

  • This means the A4 processor is probably being manufactured by Samsung.

  • The DRAM was stamped at the end of January, while the processor die was likely manufactured the third week of February.
