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.

Some motherboards are only upgradable to their allotted amount that board may only handle up to 2 gigs of RAM which is a shame. But this is the way it is. That is why I always check the board memory capacity before I buy computer boards or RAM for them. The beeps indicate error on the slots for the RAM that is why you can start up when you remove ram one at a time and replace. So use the allotted amount of RAM for that board specification or get another mother board that can handle more than 2 gigs of RAM. Sorry for the loss. Thanks for using FixYa! John

How do you install memory hp pavilion a1620n


Unplug all cables from the computer. Open the access panel (the side panel) by removing the retaining screws from the back (just a couple on that edge). Plant your feet and ground yourself to the computer (use an anti-static strap for maximum safety for your computer). Locate the memory slots. Remove old memory module if needed by pulling the clips on the ends of each memory stick out and then pushing them down. Align the new memory module so that the notches in the memory stick line up with the ridges on the slot. Push the memory module straight down until it is fully seated. The retaining clips will lock into the module when it is properly seated.

The memory will only go in one way. Do not force it - if it doesn't fit, check your alignment (try rotating the module 180 degrees). Also make sure you have the correct memory (240 pin DDR2 DIMM).

I hope this helps.

How to open my Dell Dimension 4600 to install two new gigs of ram


1) Computer off, and disconnected from power.

2) Disconnect all cables leading to your computer.

3) Lay your computer down on a table. Lay the right side towards table.
(I like to lay a clean, static free towel down on the table first, to prevent scratching the computer, or the table)

4) You are now looking at the back of the computer, with the power supply fan to the Left side.

Look underneath, along the top edge of the computer case. There is a computer case cover release latch, on the Right side. Pull the Cover Latch to the Right.

Now pull the side cover towards you. (Towards the back of the computer.

Lay the side cover aside.

5) IMPERATIVE!
BEFORE you reach inside, or take the new Ram Memory sticks out of their protective, anti-static bags, TOUCH the metal frame of the computer case!

Your body carries Static electricity. Static can fry out your computer hardware components.
Touching the metal frame of the open computer case, will relieve your body of Static.

Should you get up, walk away, then return, TOUCH the metal frame again.

Refrain from handling Ram Memory sticks by their gold plated contact pins. (Bottom of ram stick)
You can handle the ram stick anywhere else, as the body of the ram stick is coated with a see-through plastic.

6) Dell Support > Dell Dimension 4600 Series > Manuals > Service Manual,

http://support.dell.com/support/edocs/systems/dim4600/en/4600i/sm/index.htm

A) Left-click on - Removing the Computer Cover

B) Go back to this main menu, and Left-click on -
Removing and Installing Parts

Now Left-click on Memory.

Not trying to insult your intelligence, but if you have never installed Ram Memory before:

Your computer uses DDR Sdram ram memory modules, ('Sticks')
(Double Data Rate - Synchronous Dynamic Ram Access Memory)
A DDR Sdram module has on Notch on the bottom.

The Notch looks to be centered upon a cursory glance.
It is Not.
The Notch is over to one side a little.

(Actually a DDR Sdram ram memory module has 184 contact pins on the bottom.
92 on each side.
The Notch is located in-between Pins 40 and 41.
40 pins on one side of the Notch, 52 on the other side)

The Notch must be lined up correctly with the Locating Lug, in the bottom of the ram memory slot. The ram stick only goes in, in one direction.

There is a lock on each side of the ram slot. White in color, looks like an 'Ear'.
Dell's reference to a lock is 'Securing Clip'.
Put your thumbs on the top of each lock on a ram slot, and gently push down, and out.
The lock pivots to the outside.

When the locks pivot, the ram stick is raised up out of the ram slot.
Upon closer examination, you will note a small slot at the bottom of each lock.

The bottom corners of the ram stick, fit down in these slots.
Set the ram stick down in the slots of the locks, Notch lined up with the Locating Lug.
Push down on the outside top corners of the ram stick.

When the ram stick is fully seated, the contact pins will be down in the ram slot, and the locks will be seated against the sides of the ram stick.
You will notice that each lock has a 'Bump' on it. This Bump lines up with a Notch on the side of the ram stick.

The bump must be in the notch, for the ram stick to be fully seated.
Usually you will hear a satisfying 'Click - click', as the lock's bumps click into the notches.

IF, the ram memory slots that you are installing ram memory in, have never been used before, they may be tight.
You are installing new ram memory modules.
Makes the fit even tighter.

Sometimes it's a 'Pee Picker,' to get those ram memory modules to go in.
Makes beads of sweat pop out of your forehead!
Other times they slip right in with No problem.
Thought I would warn you in advance.

If I understand correctly, do I understand you are installing TWO - 1GB sticks of DDR Sdram?

[DDR Sdram at 333MHz {PC2700}, or DDR Sdram at 400MegaHertz?
{PC3200}

1) If the ram memory modules that you are installing, are larger than the ones already installed, install the 1GB ram modules in DIMM 1, and DIMM 2, ram memory slots.

DIMM 1 is Slot 1.
Slot is the ram memory slot that is closest to the Processor.
The Processor reads Slot 1, First.

DIMM 1, and DIMM 2, (Slot 1 and Slot 2), are a matched pair of ram memory slots.
They are in the same Channel.

As all clarification requests, you should be more specific so we can help you. Now your problem could most probably be that the third RAM you want to put does not comply for dual channel. If you want to use three DIMMs in a dual-channel configuration, install a matched pair of DIMMs equal in speed and size in DIMM 0 (blue) and DIMM 1 (black) of channel A. Install a DIMM equal in speed and total size of the DIMMs installed in channel A in either DIMM 0 or DIMM 1 of channel B. Your best bet is to have all your RAM in identical configurations of bus speed and size.

Ram issue with compaq presario 5000 G1 Series


as you can see from the information below there are different requirements for RAM to work stable in your system . Most importand are the RAM VOLTAGE , SPEED , and Configuration of chips. you will need to consult the manual for qualified RAM requirements. Some RAM will work but not very stable. make sure the voltage supplied by your system is enough for the RAM. If you are running DDR RAM in dual channel mode, the ram needs to be the same size also. DIMM modules for the HP computer must meet the following requirements
  • The number of pins on the DIMM must match the socket type.
  • DDR memory requires a 184-pin slot and 1.8 operating voltage.
  • DDR2 memory is not compatible with DDR1 memory and requires a 240-pin slot and 2.5 operating voltage.
  • Synchronous dynamic random access memory (SDRAM): Only use DDR type SDRAM memory if the computer came with DDR-SDRAM.
  • SO-DIMM modules for the HP computer must meet the following requirements
    • The number of pins on the DIMM must match the socket type.
    • SO-DIMM memory requires a 200-pin slot.
    • DDR2 SO-DIMMs are not compatible with DDR1 DIMM and DDR2 DIMM memory modules.
    • With a computer running at a system bus of 533 MHz or 667 MHz, use a PC2-4200 (DDR2 DIMM 533) type.
    • The following requirements must be met for the DDR memory to function in dual channel mode:
      • Same density (256MB, 512MB, etc.)
      • Same DRAM chip technology (x8 or x16)
      • All either single-sided or dual-sided
      • Matched in both Channel A and Channel B memory channels

New Motherboard for Sony VAIO-RX550


I just bought the same box, mostly for the case, power supply, etc, to use as a small server.
Three ARE 2 ram slots, but this motherborad IS limited to 512mb total. And it uses SDRAMM PC133 or 100, not SO DIMM - incompatible. PC133 SDRAM 512 is $9 (btw, installing in pairs not required on DDR SDRAM) and even if your existing is 256 & an empty slot, buying another 256 may not work, sometimes brands are incompatible. Just get the 512.

However, replacing the motherboard is your ONE chance to change lots of things at once which may be the best choice at this point. Physical size ("form factor"), CPU socket, memory type & price, graphics connections (AGP, PCIe, or built in) are key factors.

1\ the case fits a "Mini ATX" mother board (mATX). The majority of accessories use PCI lots - sound, LAN, etc. and every mother board will have 3 or more PCI slots. Probably don't need modem anymore.
2\ what CPU does it support. The original P4 1.5GHz cpu is normally a primary expense, but today your P4 Socket 478 is worth $8 (pricewatch.com) brand new. This means buying a motherboard-cpu combo may make sense. While you're at it, get more & faster memory and you'll think it's a new PC for less the $100 unless you go all out.
3\ what type & how much memory it handles & how much you have. Existing PC133 SDRAM is old & slow, about 8x faster SDRAM ddr2-800 pc2-6400 2GB is only $24 and 2GB is about the minimum today. (btw, DDR2 - notice the 2 - IS installed as a pair.) DDR is far from current, but plenty fast and very cheap, just need to balance the memory-motherboard-cpu combo.
4\ if not playing games, the video card is old but ok. It connects via the largely discarded AGP slot. So in looking at a motherboard combo, either with an AGP slot or on-board video is desirable.

From the failures its probably a RAM memory problem , which means that you should try a different ram module that is working , or if possible try the ram module of this pc in another one thats working.
