Question about IBM NetVista PC Desktop

2 Answers

Hello, i have an IBM net vista PC which is using 4 RIMM memory modules of 256Mb each, i removed one of them and later returned in position but from then henceforth my computer cant boot,instead its producing 8 short beeps. I have dealt with RAMs before and i believe the RIMMs are inserted correctly, Pliz could anyone know what the problem is?

The IBM beep code indicates no power, loose card, or short. Was the computer unplugged when you removed the module? The first thing I would do is remove all modules, blow out any dust in the memory slots, and reinsert all. While you are in there insure any cards, sound, video, are firmly seated.

The 8 beeps in apid succession upon boot indicates a memory issue
I would reseat all 4 RIMMs . If that doesn't help remove the 1 you had removed earlier along with it's mate and try again. If it boots you have a bad module

IBM T23 wont turn on after adding new RAM


Hi - according to memory suppliers your T23 has the following memory capacity / requirements:

  • IBM ThinkPad T23 maximum RAM capacity: 1GB
  • Your IBM has Two (2) memory slots or sockets
  • Module upgrade PIN count is: 144-PIN
  • The memory speed is: SDRAM 133MHz, PC133
  • The laptop DIMM type for the ThinkPad T23 is: SODIMM, SO-DIMM, Small Outline DIMM
  • Non ECC

If you are meeting these requirements, you may have a defective module.

Also, according to Lenovo's page on the machine:

Memory
The system has 128MB or 256MB of memory standard and can be configured for up to 1GB of addressable memory. Memory options up to 512MB SDRAM SO DIMMs each can be added in the two available slots for memory expansion. The standard 128MB of memory is expandable up to 640MB and the 256MB of memory is expandable up to 768 MB of addressable memory with 64, 128, 256, or 512MB SO DIMMs without removing the 128MB SO DIMM that is standard in one of the internal slots for memory. For customers that need the maximum 1GB to which memory can be expanded, it is necessary to replace the 128MB or 256MB card with a 512MB card plus add another 512MB card in the extra slot. Only 133MHz DIMM memory can be used in this system. The use of 100MHz DIMM memory is not supported in the T23 systems.

This means yo can trouble shoot the 512MB modules individually by installing one of the original 128MB modules and one of the new 512MB modules (for a total system memory of 640MB). If it does not boot, try again with the other 512MB module. This will help you identify a defective module that may be preventing the machine from booting.

I hope this helps & good luck!

Whats max RDRAM I can install on A49507-903 ?


2GB.

The Intel Desktop Board D850GB has four RIMM sockets (two sockets for each channel) and supports the following memory features:

Single- or double-sided RIMM configurations
Maximum of 32 Direct Rambus devices per channel
Total system memory configurations from 128 MB (minimum) to 2 GB (maximum) utilizing 128/144 Mbit or 256/288 Mbit technology PC600 or PC800 compliant RDRAM
Serial Presence Detect (SPD) based configuration for optimal memory operation
Suspend to RAM support
ECC and non-ECC support

When installing memory, note the following:

The four RIMM sockets are grouped into two banks:
Bank 0 (labeled on the board as RIMM1 and RIMM2)
Bank 1 (labeled on the board as RIMM3 and RIMM4)
Bank 0 must be populated first ensuring that the RDRAM installed in RIMM1 and RIMM2 is identical in speed, size, and density. For example, the minimum system configuration would use two 64 MB RIMM modules of PC600 or PC800 RDRAM.
If the desired memory configuration has been achieved by populating Bank 0, then Bank 1 should be filled with two Continuity RIMMs.
If memory is to be installed in Bank 1, the RIMM modules installed in RIMM3 and RIMM4 must be identical in size and density to each other, and match the speed of the RIMM modules in Bank 0. The RIMM modules do not, however, need to match those in Bank 0 in size and density. For example, if Bank 0 has two 128 MB RIMMs of PC800 RDRAM, Bank 1 would require PC800 RDRAM also, however, any other supported RIMM modules such as 64 MB or 192 MB could be used.
If ECC functionality is required, all installed RIMM modules must be ECC-compliant.

I just need to upgrade the memory on a Dell Precision 530MT.. can't seem to find the exact type of memory it needs.. any ideas?


HELLO Paul

When installing memory modules in the system board sockets and not using the optional memory riser boards, observe the following guidelines:
  • Each memory socket on the system board must be occupied either by a RIMM or a CRIMM.

  • Memory sockets must be upgraded in matched pairs. In other words, two sockets in a pair must contain modules of identical capacity, number of components, and speed. See "System Board Memory Components" to identify pairs of sockets.

  • Mixed pairs of ECC and non-ECC modules all function as non-ECC.

  • Be sure to install a RIMM in socket 1 first (closest to the processor) before installing modules in the other sockets.

  • The system board supports PC600 and PC800 memory modules.

I would like to nwom how much of memory this laptop support


The Thinkpad is installed with 128 MB SDRAM is standard, and is expandable to 512 MB
There are two memory slots, to expand it to 512 Mb you need two 256 Mb RAM modules and throw away the 128 Mb RAM module, but if you don't throw away this module and you insert a 256 Mb RAM module in the 2nd memory slot then your total memory would be 384 Mb.

Looking for the manual for a Gateway 700S PC. Specifically 2 questions ... 1) how do I open the ATX tower case? and 2) what EXACT memory specs do i need to upgrade this unit from the 256MB that it came...


Hello,
for the memory upgrade, your system used RDRAM RIMMS.
it supports the following memory modules (which must be installed in pairs).

and as for opening the case, you there should just be ~2 screws on the side panel away from the motherboard ports that you can remove and it will slide off, or there might be 1 or 2 thumb screws.

64MB Module 64MBx16, 800MHz PC800, 184p RIMM, RDRAM, 45ns, 2.5v PC800-Kit-136 128MB Module 128MBx16, 800MHz PC800, 184p RIMM, RDRAM, 45ns, 2.5v PC800-Kit-079 512 MB Kit 256MBx16, 800MHz PC800, 184p RIMM, RDRAM, 45ns, 2.5v PC800-Kit-081 64MB ECC Module 64MBx18, 800MHz PC800, 184p RIMM, ECC, RDRAM, 45ns, 2.5v PC800-Kit-134 128MB ECC Module 128MBx18, 800MHz PC800, 184p RIMM, ECC, RDRAM, 45ns, 2.5v PC800-Kit-080 512 MB ECC Kit 256MBx18, 800MHz PC800, 184p RIMM, ECC, RDRAM, 45ns, 2.5v PC800-Kit-082

Memory limit for my dell E139761 motherboard


Although the motherboard ultimately decides how much memory your system can handle, Dell does not list the specifications of motherboards. You need the model number of the computer, and if the motherboard is not the original one that came in the computer when it was built by Dell they won't know either.

You can go to dell.com and put in your service tag to see the specifications yourself. If you post the computer model number or service tag here that's what someone else will do anyway.

IBM ThinkPad T40 2GB Max RAM


The T40 has two ram slots, you can put a 1g chip in each totaling 2g. If the chip will remove, then it is changeable. Vista needs a minimum of 256 to run, so, when you change BOTH chips to equal 2g it will probably read 1.744g, or it may read the full 2g. If it only reads 1g, then the second slot under keyboard may have malfunctioned. It could also be that the 256 chip is bad and your really only running 512 now. With all that said, in order to achieve 2g, you will need to put a 1g chip in each slot.

Ram upgrade


Step 5: Remove a memory or continuity module Continuity modules do not contain memory, but are placeholders to close the memory circuit. Use the following steps to remove a memory or continuity module:
  1. Pull out, and then press down on the holding clips that retain the memory modules. The memory modules should rise up slightly out the socket. Figure 5: Opening memory module tabs c00571682.gif
  2. Pull out the memory or continuity module (for RIMMs) and place it in a static-safe container.
Step 6: Add a memory module Use the following steps to insert a memory module into an empty socket:
  1. If RIMMs are being used, keep the following items in mind when purchasing and installing modules:
    • The memory configuration of channel A (the first two sockets) and channel B (the second two sockets) must be identical.
    • Continuity RIMMs must fill any open memory sockets.
    • When a continuity RIMM is required, it should be installed into the second socket.
  2. Align the memory module so the small notches on the lower edge line up with the raised marks in the socket. Figure 6: Memory module installation c00571683.gif 1 - DIMM (notches farther apart) 2 - RIMM (notches close together)
