Re: memory module

Your motherboard supports 533MHz memory modules, no more. If you put anything higher in, it will work, but only at the speed of 533MHz, so there's not much point in aiming any higher. Just make sure what you're buying is a DDR2 533MHz memory module, and it's best to get them in increments of 2. If you have 4 slots on your motherboard, get another 2x512MB modules of RAM. If you're running Windows Vista, it might be worth considering 2x1GB modules. I think that pretty much covers your question, if you have anything else to ask, feel free to reply.

This is a sign of a memory failure. You will need to open the case and remove all of the memory.

Remember to ground yourself before starting. To open the case, disconnect all external cables (including the power cord), then lay the machine on it's side with the cover up. Slide and hold the latch on the back, if there is one, then grip the cover at the indents and slide the cover towards the back of the computer.
The memory sticks are held to the motherboard by clips on the ends of stick that need to be pushed away from the stick.

Then reinsert one memory stick. The modules will only fit the slots one way. There is a notch that lines up with the motherboard slot. If it doesn't line up, turn the memory around (pins of cross face into the motherboard). When the memory module is fully seated, the clips should automatically pop to lock into the notches on the ends of the memory stick. Then turn on the computer. If it boots normally, shut down and add another memory stick then restart again. If it gives the error again and you have multiple memory modules, take out the first one and try a different memory stick. (Similarly as you add memory, any stick that causes a problem should be removed until you have tested all of them and only the good memory modules are still in the computer.)

If the machine is under warranty, contact Dell for replacement memory modules. Otherwise, replace them with compatible memory if you want to maintain that amount of memory in the computer (most manufacturer's have a tool to look up the correct memory for a given machine). Memory is sold at most of the computer stores and repair shops, online computer stores as well as directly by some manufacturers. The memory needs to be 400 MHz or 533 MHz unbuffered, non-ECC DDR2 SDRAM (however, Dell often uses propriety RAM so again check the compatibility).

I hope this helps.

My Dell Dimension 9150 is unstable. The Dell Diagnostic indicates memory failure in DIMM socket 3. I reversed the modules in the DIMM sockets and Dimm socket 3 failed again. Motherboard?? My motherboard...

Yes you can. Your best is to use the largest and best ram in the number one slot. I would remove ALL the ram and start with the 2 gig in the first slot - then add others until you get the error message - remove that one and keep the rest.

I bought a pentium 4 3.0 ghz 800 mhz & my

The motherboard chipset of the Dell Dimension 2300 Desktop PC, will not support a processor with an 800MHz Front Side Bus frequency rate.

Only Intel Pentium 4's that use a Socket 478, 1.75 Volts, and a maximum of a 400MHz FSB.

The Intel Pentium 4 HT 3.0GHz processor has an 800MHz FSB, (As you have already stated), and uses 1.475 to 1.55 Volts.

The motherboard chipset for that Dell Dimension 2300, is an Intel 845GL.

This list on Wikipedia, shows you parameters the Intel 845GL chipset supports,

Not a good outcome, sorry. Just stating the facts.

My dell power light was off one morn,but my

Seems to be a Memory or a Motherboard failure. Make sure the memory you upgraded are the ones which are compatible to the system.
The compatible memory modules for your system are:
DIMM, 128MB, DDR2, 400M, 16X64, 8, 240pins
DIMM, 256MB, DDR2, 400M, 32X64, 8, 240pins
DIMM, 512MB, DDR2, 400M, 64X64, 8, 240pins
DIMM, 1G, DDR2, 400M, 128X64, 8, 240pins

The power light not turning on can be the Front bezel issue and not a system/motherboard failure. Please revert for any more issues.

Computer will not boot

Hi Zany913,

3 and 4 solid green lights indicate that the memory is detected but there is an error. First reseat the memory modules. Then try one at a time.

If nothing happens, I'm afraid you'll need to call dell for replacement RAM.

I hope this helps,

Memory Upgrade Attempt Causes Computer Not to Post

Seeing as the message is indicating a problem at one of the timer checkpoints, fatal is probably an accurate description. You are most likely looking at a motherboard replacement scenario. I've seen improperly seated memory modules toast timer circuitry on old boards back in the days when most of the timing circuitry was constructed from discrete components, not entirely IC-based timing solutions, but I have never seen it happen on modern boards.

You may have bad or incompatible Ram . Verify that the memory you have is compatible. .

Machine name: Dell Dimension 3000
CPU options: Intel Pentium 4 or Intel Celeron
Chipset: Intel 865GV Chipset
HD Bus: Ultra ATA/100
Front Side Bus options: 800MHz FSB
Memory Speed options: PC3200 DDR400 184pin SDRAM DIMM
Special notes: The Dimension 3000 has two different bus speeds each of which takes different memory. You cannot mix the speeds.

Take the memory out and install one at a time. This way you can verify that the memory is indeed working. If you find a bad one, replace it.

If I could be of further assistance, let me know. If this helps or solves the issue, please rate it.
Thanks, Joe

I get "virtual memory low" message and cannot boot.

The real solution to this is going to involve spending some money to buy some new memory. It should cost about $30-50 depending on type and amount. 256Mb is not enough for Windows and other software to run. I would recommend buying at least 512Mb additional to add. Before you purchase open up your machine and look to see how many memory slots you have and how many are currently used. According to some specs on the internet, here is what you have.

Maximum Memory 2GB Memory Slots 2 (1 bank of 2) Install in pairs non-removable base memory 0MB Machine name: Dell Dimension 3000
CPU options: Intel Pentium 4 or Intel Celeron
Chipset: Intel 865GV Chipset
HD Bus: Ultra ATA/100
Front Side Bus options: 800MHz FSB
Memory Speed options: PC3200 DDR400 184pin SDRAM DIMM
Special notes: The Dimension 3000 has two different bus speeds each of which takes different memory. You cannot mix the speeds. Please check the speed on the memory modules currently installed, or use our "Check Your Computer" to find the correct module.
It is simple enough most anyone can do this themselves, and I could walk you thru it, otherwise you would need to take it somewhere, but my recommendation would be to do it yourself and simply ask me or others here for advice. Let me know if you want help to do this.
Good Luck!

PNY memory


Dell Dimension 5150 supports DDR2 400MHz (PC2-3200) and DDR2 533MHz (PC2-4300) unbuffered SDRAM Memory (DIMM). You may install a total of four DIMMs in capacities of 256MB, 512MB, or 1GB. The maximum memory supported is 4GB.

From your query, I think the obvious question is; What is specification of the PNY DIMM and/or does the PNY DIMM meet the requirements for Dimension 5150?

Check for memory configuration and installation procedures for Dimension 5150 -

The Chipset used on Dimension 5150 is Intel 945G Express. I am not aware of specific compatibility issues regarding the Intel 945G and PNY Memory modules. However, there may really be known issues that I am not aware of.

To proceed, ensure that the PNY Memory is compatible with Dimension 5150. If not, install compatible (memory type, speed, capacity) DIMMs.

Let me know if further help is needed.
