Would this memory be ok for my emachine 730 desktop?

Question

1GB (2x 512MB ) PC133 SDRAM DIMM Memory ECC Reg 168-pin.

Yes it is PC133 SDRAM etc But what does the DIMM and ECC mean?

Answer 1

DIMM = Duel in-line Memory Module & ECC = Error Correcting Codes

Answer 2

All SDRAM is c168-pin DIMM. format. 133 refers to the bus clock speed and matches what you are looking for, it would also be OK if your machine required PC100 or PC66 RAM as it is backwards compatible with slow speeds though obviously it doesn't work the other way round. PC100 memory in a PC133 memory slot would be totally unreliable, although if you want to be really technical you can go into your BIOS and slow the memory speed down to 100.

DIMM - Dual Inline Memory Module - don't worry too much about that - standard physical format.

ECC - Error Correction Code - an extra parity bit is sent to determine whether there is an error in the data passed back and fore from the Ram chip (i.e. it doesn't lose anything stored on it).

The show stopper for you though will probably the fact that the RAM chips you are looking at are registered, your machine probably cannot use registered RAM.

FYI - ECC and registered means that this RAM is high end and destined for a server.

Answer 3

its not the really the model of the machine, but that model of the motherboard would be required.
it should work fine.
A DIMM, or dual in-line memory module comprises a series of random access memory integrated circuits. These modules are mounted on a printed circuit board and designed for use in personal computers. DIMMs began to replace SIMMs (single in-line memory modules) as the predominant type of memory module as Intel's Pentium processors began to control the market.

The main difference between SIMMs and DIMMs is that SIMMs have a 32-bit data path, while DIMMs have a 64-bit data path. Since Intel's Pentium has (as do several other processors) a 64-bit bus width, it required SIMMs installed in matched pairs in order to use them. The processor would then access the two SIMMs simultaneously. DIMMs were introduced to eliminate this inefficiency. Another difference is that DIMMs have separate electrical contacts on each side of the module, while the contacts on SIMMs on both sides are redundant.

The most common types of DIMMs are:

72-pin-DIMMs, used for SO-DIMM
144-pin-DIMMs, used for SO-DIMM
200-pin-DIMMs, used for SO-DIMM
168-pin-DIMMs, used for FPM, EDO and SDRAM
184-pin-DIMMs, used for DDR SDRAM
240-pin-DIMMs, used for DDR2 SDRAM
There are 2 notches on the bottom edge of 168-pin-DIMMs, and the location of each notch determines a particular feature of the module.

The first notch is DRAM key position. It represents RFU (reserved future use), registered, and unbuffered.
The second notch is voltage key position. It represents 5.0V, 3.3V, and Reserved.
The upper DIMM in the photo is an unbuffered 3.3V 168-pin DIMM.
A DIMM's capacity and timing parameters may be identified with SPD (Serial Presence Detect), an additional chip which contains information about the module type.

ECC DIMMs are those that have extra data-bits which can be used by the system memory controller to detect and correct errors. There are numerous ECC schemes, but perhaps the most common is Single Error Correct, Double Error Detect (SECDED) which uses a 9th extra bit per byte.

Answer 4

Your computer can hold a max of 1.5gb of Pc133 sdram non-ecc, ecc reg ram wont work with your computer ,ecc ram is slower and for servers.

Answer 5

Which eMachine? some have been given solid comments, some did not. in specific, I purely went over quite a few comments for the EL1200-05, that have been given incredibly damaging comments on CNET via fact it is so underpowered. Even those different components that gave it better scores agreed that it grow to be specially solid purely for internet surfing and working 'undemanding' domicile windows classes.

Answer 6

1gb is a good amount of RAM
ECC=Error Correcting Code
DIMM= Dual Inline Memory Module
