Internal Components (Cont’t)
The memory in our laptop is 3 GB, in one 2 GB and one 1 GB modules, both DDR3-1333 (PC3-10700) from Kingston. Even though it is a reasonable configuration to work with 32-bit and 64-bit operating systems, the problem with this configuration is that it is impossible to use the existing modules if you want to upgrade the RAM quantity, since both slots are used. The Aspire 5750 supports up to 8 GB memory, using two modules with 4 GB each.
The wireless network card that comes in the Aspire 5750 is an Atheros AR5B97, which complies with the IEEE 802.11b/g/n standards.
The optical unit is a DVD-rewriter from Philips/Lite-on, model DS-8A5SH, seen in Figure 13. This unit reads and writes CDs with 24x speed, read DVDs at 8x, records DVD+R, DVD-R, and DVD-RW at 8x, and DVD+R DL and DVD-R DL at 4x.
