Acer Aspire 5100-5400 compatible with Corsair PC2-5300 2GB 2X1GB Dual Channel kit?


Recommended Posts



First post and couldn't find the answer in the memory finder as it doesn't list my laptop. Acer Aspire 5100-5400 AMD X2 TL50 (1.6GHz) ATI Radeon Express 1100, 512 MB RAM (PC 4200 533 I assume). The manual says two slots, max 4GB RAM, and can handle either 533 or 667 RAM. Would this kit work?

If not what additional RAM can I add to the existing 512? Is it OK to add a stick of PC5300 (667) rated RAM alongside the stock RAM and it will downgrade to PC4200 if that's what the OEM is,

Model#: VS512SDS667D2


If neither of those options work, which specific RAM will work with the existing RAM (don't require it to be in dual channel if I'm just adding an additional stick) or a dual channel kit to replace the OEM altogether?

why do you want to set 667MHz memory? If you use a single channel (1 PC2-5300 module or 2 modules with different sizes) you will get the FSB speed of 667 MHz

Acer 5100 uses 800 MHz FSB in dual channel mode (Turion FSB), so if you install PC2-5300 memory kit the notebook won't exceed speed of 800 MHz.

Instead, using a PC2-5300 will not improve performance as effective as using a PC2-4200 kit, because PC2-5300 memory has CL latency 5-5-5 and PC2-4200 has CL 4-4-4

If you want to add a second modute to existing one, see my post about Acer 5105 notebook memory:

Ive recently bought the second memory module Corsair VS512SDS533D2 for my Acer Aspire 5101AWLMi LX.AX80J.001.

Unfortunately I did'nt see any entries like "Dual channel" behind a splash screen or in Acer Management utilites, so I used PCMark2005 to compare single module and dual modules performance:

read speed increased to 60 per cent

write speed increased to 52 per sent

I think now my system posts dual-channel :biggrin:
