I'm afraid you have misunderstanding about pitch notation. See Wikipedia entry for scientific pitch notation. E3 is not high. It's lower than the middle C (C4). The middle C is the C which is the nearest from the key hole of the piano.

According to Crypton's official announcement, Miku's optimum range is A3 ~ E5. The frequency of E5 is about 659Hz, which is not very high.

An important point: Crypton uses scientific pitch notation, and Yamaha uses Yamaha notation. In Yamaha notation, the middle C is C3. Yamaha C3 = Crypton C4, Yamaha C4 = Crypton C5, Yamaha C5 = Crypton C6, and so on. OK?

The upper limit of Miku's optimum range is E5 in scientific pitch notation (Crypton E5). Yamaha notation is used in Vocaloid editor, because the editor is a product of Yamaha. So, if you input a note at E5 in Vocaloid editor, then it's Yamaha E5, that is Crypton E6. The frequency of E6 is about 1319Hz which is very high. I'm afraid this may cause a misunderstanding that Miku's voice is incredibly high.

You can see the recommended key range map here. Note that it's written in Yamaha notation. Miku's range is A2~E4 in Yamaha notation. Compare it with the ranges of V3 voicebanks shown in the map. Then you'll understand Miku's range is not high.
