Gateway 838GM - Memory Rejected

[et6579]

I've recently been trying to upgrade the memory in an 838GM, and so far it's rejected all of it. On startup it will give the three beeps indicative of a memory error, and fail to POST. I have only been using PC3200 that was specifically recommended for use in an 838GM, and have tried pairs of 256mb, 512mb, and 1gb sticks thus far, so there shouldn't be any compatibility issues. Also tried updating the BIOS, but the latest version is from 2006, and I found that this PC already has that version.

So what are my options now? Are there any BIOS or jumper settings I'm overlooking? I've done a bit of research on the 'net, and it seems like nobody has ever had any problems upgrading the memory in their 838GM PCs.

Q: What are the supported memory configurations for the Augsburg motherboard?

A: The following table lists the supported memory configurations for the Augsburg motherboard:

Dimm Capacity Configuration SDRAM
Density SDRAM Organization
Front-Side/Back-Side Number of
SDRAM Devices
128 MB SS 256 Mbit 16 M × 16/empty 4
256 MB SS 256 Mbit 32 M × 8/empty 8
256 MB SS 512 Mbit 32 M × 16/empty 4
512 MB DS 256 Mbit 32 M × 8/32 M × 8 16
512 MB SS 512 Mbit 64 M × 8/empty 8
512 MB SS 1 Gbit 64 M × 16/empty 4
1024 MB DS 512 Mbit 64 M × 8/64 M × 8/ 16
1024 MB SS 1 Gbit 128 M × 8/empty 8
2048 MB DS 1 Gbit 128 M × 8/128 M × 8/ 16

Note: In the second column, “DS” refers to double-sided memory modules (containing two rows of SDRAM) and “SS” refers to single-sided memory modules (containing one row of SDRAM).

It is possible to install four 2048 megabytes (MB) - 2 gigabytes (GB) modules for a total of 8 GB of system memory, however, only 4 GB of addressable memory space is available.

The Intel® 82915G GMCH supports two types of memory organization:

* Dual channel (Interleaved) mode. This mode offers the highest throughput for real world applications. Dual channel mode is enabled when the installed memory capacities of both DIMM channels are equal. Technology and device width can vary from one channel to the other but the installed memory capacity for each channel must be equal. If different speed DIMMs are used between channels, the slowest memory timing will be used.
* Single channel (Asymmetric) mode. This mode is equivalent to single channel bandwidth operation for real world applications. This mode is used when only a single DIMM is installed or the memory capacities are unequal. Technology and device width can vary from one channel to the other. If different speed DIMMs are used between channels, the slowest memory timing will be used.

The following graphics illustrate the memory channel and DIMM configuration.

Note: The DIMM0 sockets of both channels are blue. The DIMM1 sockets of both channels are black.

* Dual Channel (Interleaved) Mode Configurations

This graphic shows a dual channel configuration using two DIMMs. In this example, the DIMM0 (blue) sockets of both channels are populated with identical DIMMs.

Dual Channel (Interleaved) Mode Configuration with Two DIMMs

This graphic shows a dual channel configuration using three DIMMs. In this example, the combined capacity of the two DIMMs in Channel A equal the capacity of the single DIMM in the DIMM0 (blue) socket of Channel B.

Dual Channel (Interleaved) Mode Configuration with Three DIMMs

This graphic shows a dual channel configuration using four DIMMs. In this example, the combined capacity of the two DIMMs in Channel A equal the combined capacity of the two DIMMs in Channel B. Also, the DIMMs are matched between DIMM0 and DIMM1 of both channels.

Dual Channel (Interleaved) Mode Configuration with Four DIMMs

* Single Channel (Asymmetric) Mode Configurations

This graphic shows a single channel configuration using one DIMM. In this example, only the DIMM0 (blue) socket of Channel A is populated. Channel B is not populated.

Single Channel (Asymmetric) Mode Configuration with One DIMM

This graphic shows a single channel configuration using three DIMMs. In this example, the combined capacity of the two DIMMs in Channel A does not equal the capacity of the single DIMM in the DIMM0 (blue) socket of Channel B.

Single Channel (Asymmetric) Mode Configuration with Three DIMMs
