Question about Acer Computers & Internet

1 Answer

I have an acer extensa 5620-6830 with 1g memory on a dual core which means I only have 512m for each core. Right? What is the most memory I can add and not having done this before what kind of memory chip do I buy? Thanks

DUAL CORE refers to the amount or cores your PROCESSOR has, Memory indicates the TOTAL amount for the WHOLE SYSTEM, NOT the cores or the precessor. You should be able to max out your memory @ 4gb, but check your machine specs at Acer website for Max amount and type.

Acer official site says:-
Up to 4 GB DDR2 533/667/800 MHz SDRAM
(dual-channel support on four DIMMs)

Try these bus speeds and for dual-channel support read this article :-

Dual-channel architecture requires a dual-channel-capable motherboard and two or more DDR, DDR2 SDRAM, or DDR3 SDRAM memory modules. The memory modules are installed into matching banks, which are usually color coded on the motherboard. These separate channels allow each memory module access to the memory controller, increasing throughput bandwidth. It is not required that identical modules be used, but this is often recommended for best dual-channel operation. It is possible to use a single-sided module of 512 MB and a double-sided module of 512 MB in dual-channel configuration, but how fast and stable it is depends on the memory controller.

If the motherboard has two pairs of differently colored DIMM sockets (the colors indicate which bank they belong to, bank 0 or bank 1), then one can place a matched pair of memory modules in bank 0, but a different-capacity pair of modules in bank 1, as long as they are of the same speed. Using this scheme, a pair of 1 GB memory modules in bank 0 and a pair of matched 512 MB modules in bank 1 would be acceptable for dual-channel operation.

Modules rated at different speeds can be run in dual-channel mode, although the motherboard will then run all memory modules at the speed of the slowest module. Some motherboards, however, have compatibility issues with certain brands or models of memory when attempting to use them in dual-channel mode. For this reason, it is generally advised to use identical pairs of memory modules, which is why most memory manufacturers now sell "kits" of matched-pair DIMMs. Several motherboard manufacturers only support configurations where a "matched pair" of modules are used. A matching pair needs to match in.

Good luck

They are NOT compatible with *********** Board. See one is single core & the other Dual Core, & your BIOS isn't programed to use the Dual Core.

ive found the best prices at tigerdirect.com and they ship it right to your door. make sure the tiger ppl have the exact match and dont replace your order with more expensive replacements as some of these substitutions require voltages that your motherboard CAN NOT produce and will not work.. you also want to make sure to buy low density ram, it performs better, is a few bucks more than high density, but worth EVERY penny. E-bay is notorious for selling cheap high density ram on thier site.
If you stick to the list above, you shouldnt have any issues.
This should fixya up! please rate...
