  • 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.

取下逻辑主板上的电磁干扰屏蔽罩。

这块板与我们发现的预生产主板明显不同。

表面有A4标记:

编码：N26CGM0T 1007 APL0398 33950084 YNL184A2 1004 K4X2G643GE

是的，K4X2是三星DRAM零件号!

解码零件号显示里面有2Gb的内存。这将转换为~128MB的内存，为256 MB的总数。(不像我们之前报道的512MB)。

这意味着A4处理器可能是由三星制造的。

DRAM在1月底被标记，而处理器芯片可能在2月的第三个星期制造完成。
