Question about Gateway 507GR PC Desktop

2 Answers

Installing Memory I recently purchased a pair of DIMM RAM to double my current RAM and I am having issues. The question I have is, should the matching pairs of memory cards be installed next to each other? I ask because the stock memory came installed in opposite slots (there are four memory slots, and what came with the computer was installed in slots 1 and 3). Should I remove the RAM and place the matching pairs in slots 1&2/3&4 respectively, or are they meant to be the other way? Thank you for your time. ~Erek

    *nods* Thank you. The slots are indeed colour-coded (slots 1&3 being white and 2&4 being black). I have kept both the pre-installed memory and the new memory in matching coloured slots as I generally assumed they need be. Although, I did notice that the pre-installed memory is one-sided, as opposed to the new memory I purchased which is two-sided. Could this be causing any issues? I have also run a memory diagnostic which found no errors.

    Note: The pre-installed memory modules are each 256MB, and the two new are each 512MB (PNY DDR PC3200, 400MHz/333MHz/266MHz, Optima Memory).

Put the new ram in slots 2 and 4.

Slots 1 & 2 are channel 1 slots 3 & 4 are channel 2, you need matching sets in each channel to run dual channel mode.

That is not always the case! Many computers DO come with alternate ram slots. Meaning... that slots 1 and 3 would be the place you would want matching pairs. As well as in 2 and 4... If that computer came from the factory with 2 chips and they were in 1 and 3, chances are they should stay there. The new chips should then be placed in 2 and 4 to be matched. Are the slots color coded at all? The color codes indicate which slots are for matched pairs as well. It depends on the individual motherboard and to safely answer this person's question, one would need to see a picture of the main board or know the model number first.

The manual for your motherboard states:

For dual-channel memory configuration (2), you may:

• install identical DIMMs in all four sockets OR

• install an identical DIMM pair in DIMM_A1 and DIMM_B1 (yellow

sockets) and another identical DIMM pair in DIMM_A2 and

DIMM_B2 (black sockets)

* Always use identical DDR2 DIMM pairs for dual-channel model. For

optimum compatibility, we recommend that you obtain memory modules
from the same vendor.

I am having Intel Board SE7501BR2, i wanted to know how much RAM does it support and of what speed, because currently it is having 512 mb ram with speed of DDR$266 mhz.


This motherboard can support up to 2Gb of DDR266 RAM modules.

Attached is part of the memory detail from the manual.

If you need a copy of the manual. please click on this link to download :-

ftp://serwery.optimus.pl/Servers/Motherboards/SE7501BR2/Dokumenty/se7501br2tps.pdf



3.1.2.2 Memory Configuration

Memory interface between the MCH and DIMMs is 144 bits wide. This requires that two DIMMs

be populated per bank in order for the system to operate. At least one bank has to be populated

in order for the system to boot. If additional banks have less than two DIMMs, the memory for

that bank(s) will not be available to the system.

There are two banks of DIMMs, labeled Bank1 and Bank2. Bank1 contains DIMM locations

DIMM1A and DIMM1B and Bank2 contains DIMM2A and DIMM2B. DIMM socket identifiers are

marked with silk screen next to each DIMM socket on the baseboard. The sockets associated

with any given bank are located next to each other.

The baseboard's signal integrity is optimized when memory banks are populated in order.

Therefore, DIMM Bank1 must be populated before Bank2.

DIMM and memory configurations must adhere to the following:

• DDR266 DDR registered DIMM modules

• DIMM organization: x72 ECC

• Pin count: 184

• DIMM capacity: 128 MB, 256 MB, 512 MB, 1 GB, 2 GB

• Serial PD: JEDEC Rev 2.0

• Voltage options: 2.5 V (VDD/VDDQ)

• Interface: SSTL2

• Two DIMMs must be populated in a bank for a 144-bit wide memory data path

• One or two memory banks may be populated

Table 2. Memory Bank Labels

Memory DIMM Bank Row

J8D22 (DIMM 1A), J8D15 (DIMM 1B) 1 0, 1

J8D7 (DIMM 2A), J8D1 (DIMM 2B) 2 2, 3

Note: Memory must be installed in pairs; DIMM Bank1 must be populated before DIMM Bank2.

Memory within a DIMM bank must be identical; between banks only the DIMM size may be

different.

Anyone know why an ASUS PTGD1-LA motherboard will only take memory in slots A1 and A1 or A1 and B1 but not anything in B with both in A filled? Brand new memory.


HI,

The board has specific requirements for memory. Here's the Memory Configurations :

  • You may install 256 MB. 512 MB and 1 GB unbuffered non-ECC DRR DIMMs into the DIMM sockets using the memory configurations in this section.

• Installing DDR DIMM. Other than the recommended configurations may cause memory sizing or system boot failure.

• In dual-channel configurations, install only Identical (the same type and size) DDR DIMM pairs for each channel.

• Always install DIMMs with the same CAS Latency. For optimum compatibility , It Is recommended that you obtain memory modules from the same vendor

• Double-sided x 16 modules are not supported on this motherboard.

• Due to chipset resource allocation, the system may detect less than 4 GB system memory when you installed four 1 GB memory modules.


For dual-channel configuration you may:

install identical DIMMs in all four sockets

• install identical DIMM pair in DIMM_A1 and DlMM_B1 (blue sockets) and identical DIMM pair in DIMM_A2 and DIMM_B2 (black sockets)

• install same size DIMMs in DIMM_A1 and DIMM_B1 (blue sockets) and another same size pair in DIMM_A2 aid DIMM_B2 (black sockets)

Hopefully this will help understand how to install the new memory.

Thanks Mark

Memory


Ok well there could be a few things going on here. It is possible that A: your third stick is damaged which I'm assuming you dismissed through your installation of one at a time, B: the third dimm slot is damaged and is unusable, C: the dimm slot is turned off in your bios. 

Now looking at the Shuttle A161 motherboard it would appear you have a primary dimm slot and then expansion dimm slots (technically these are called the controller dimm slot and the estensions) 

The controller slot which is offeset from the other two should have your largest ram, make sure the ram you stick in this slot isn't a stick that requires dual recognition. Some ram is designed to work in a pair even in the early PC100 class ram. Most PC100 ram you'll find now requires the sticks to work in pairs and the ram is coded for this. (Especially since PC100 is on its way out very fast.) The expansion slots can be fitted with a pair that will work together. I doubt that your third and primary slot is turned off as it is the controller slot. If none of your ram works in this slot replace the old ram in to this slot and just use the two expansion slots. It may not be as much ram as you want but the motherboard has presets that are just problematic. 

My general advice however is, that if you're running this motherboard which is fairly out of date, I'd upgrade to a new computer. Buying a cheap Dell desktop or even a barebones off of newegg.com and transfering your current Harddrive and what not over would probably be easier for you and will carry you for the next five years or so.

I have a P3 at 500MHz and was wondering with this Motherboard,


The motherboard has three, dual in-line memory module (DIMM) sockets. Minimum memory size is 16 MB; maximum memory size is 768 MB. The largest DIMM supported at this time is 256 MB using unbuffered 128 Mbit technology parts. The BIOS automatically detects memory type, size, and speed.

The motherboard supports the following memory features:
  • 168-pin DIMMs with gold-plated contacts
  • 66 or 100 MHz SDRAM
  • Non-ECC (64-bit) and ECC (72-bit) memory
  • 3.3 V memory only
  • Unbuffered Single- or double-sided DIMMs in the following sizes:


DIMM Size Non-ECC Configuration ECC Configuration 16 MB 2M x 64 2M x 72 32 MB 4M x 64 4M x 72 64 MB 8M x 64 8M x 72 128 MB 16M x 64 16M x 72 256MB 32M x 64 32M x 72

Synchronous DRAM (SDRAM) can be installed in one, two, or three sockets. EDO DIMMs are not supported. Memory size and speed can vary between sockets.

Note: Intel® Pentium® II processors with 100 MHz front-side bus should be paired only with 100 MHz SDRAM. Processors with 66 MHz front-side bus can be paired with either 66 MHz or 100 MHz SDRAM.

All memory components and DIMMs used with the Intel® SE440BX-2 motherboard should comply with the PC SDRAM specifications. These include: the PC SDRAM Specification (memory component specific), the PC Unbuffered DIMM Specification, and the PC Serial Presence Detect Specification.

Note: It is recommended that SPD memory DIMMs be used with the SE440BX-2 motherboard. However, the BIOS will allow the use of non-SPD DIMM memory.

So the max you can go is 3 x 256 MB.

Thanks and please take a moment to rate fixya.

Will not recognize Ram


Insert a pair of memory so you again can see a total memory of 1024GB. Check the slots you have them inserted in. It should be DIMM A-1 & B-1. (Correct)? Remove both & insert the second pair. Use A-1 & B-1 again. Check total memory reported by bios. If you see anything less than 1024GB, that set of memory has an issue. Continue to leave in that set of memory. Go to this link & download memtest86 to a floppy disk & test the memory. You'll find the download section just under the three screen shots.
http://www.memtest.org/
Each set of dimm's should be placed like so. One matched pair in dimm A-1 & B-1. Second set insert into dimm A-2 & B-2. The bios should see the total as 2GB. Run memtest only while using one set of matched 2x512 memory at a time. If there is a problem with the memory memtest86 will find it.
Though the information should fix you're issue, (or catch some bad memory).
It wouldn't hurt to check if a bios upgrade will help also.
Click on this link & check you're bios version against Asus updates. Please only update if you are sure the update will help.

Hello My ASUS K8V-MX Motherboard has only two memory slot


Look into you're manual, go to pages 1-11 & 1-12.
The memory listed here has been tested by Asus to work correctly in the K8V-MX motherboard. In order for you to reach 2GB memory you will need DS memory. Double sided. This means there is 512MG on each side of a single DIMM, hence 2x1x 512MB DIMM equals 1GB. So you will need 4x 512MB to raxhl a total memory of 2GB. Please stay within the recommended memory listed on the Qualified Vendor List (QVL).
Simptronics memory it not on the QVL list. From time to time some memory not one the list may still function. This is not one of those times.

When i add a memory in damaged DIMM slot showing black screen?


Try moving the working DIMM to other slots, it should work in any slot, if it does, the other ram u have is incompatible or bad

Install a matched pair of DIMMs (equal in speed: DDR266, DDR333, or
DDR400; density: 64 MB, 128 MB, 256 MB, 512 MB, or 1 GB; and
technology: 128 Mb, 256 Mb, or 512 Mb) in DIMM 0 in both Channels A and
B. If additional memory is to be used, install another matched pair of DIMMs
in DIMM 1 in both Channels A and B.
