We have an Intel Pentium 4 running WinXP. A lot of games are used. The computer is very sluggish and in games it is really lagging. We recently added another drive to give us more space. We have had a 'low vitual memory' warning. Have since decided to add more RAM. There are 3 memory slots, 2 originally had 512 RAM in each, so we added 512 in the 3rd slot. It doesn't seem to recognise the new RAM in 3rd slot. Do we have to enable this memory slot? If so, how? Have included some info from EVEREST:

First try moving stick three to slot 1 and leave the others out and see if it boots (I'm sure it will but try it anyways). Second, and follow close, move stick two, to slot 3 and stick 3 to slot 2. Reinstall stick 1 in slot 1. We want the faster RAM in slot 3. The 200mhz RAM should be last.

Thanks Acklan for responding.

Do as you suggested, but still no improvement. If anything, we think computer is even slower.

Memory Slot 3 is still not being recognised in Everest report in that it does not add another 512 RAM to its total memory. It does however list each card as it did before.

Motherboard:
CPU Type Intel Pentium 4, 2400 MHz (18 x 133)
Motherboard Name Gigabyte GA-8GE800 (5 PCI, 1 AGP, 3 DDR DIMM, Audio, Video)
Motherboard Chipset Intel Brookdale-G i845GE
System Memory 1024 MB (DDR SDRAM)

SPD Memory Modules:
DIMM1: Jade Star Tech. 512 MB PC2700 DDR SDRAM (2.5-3-3-7 @ 166 MHz) (2.0-3-3-6 @ 133 MHz)
DIMM2: Nanya M2U51264DS8HC3G-5T 512 MB PC3200 DDR SDRAM (3.0-3-3-8 @ 200 MHz) (2.5-3-3-7 @ 166 MHz)
DIMM3: 64MX64U-40B 512 MB PC3200 DDR SDRAM (2.5-3-3-8 @ 200 MHz)

Thanks for your assistance.

Hi 60jasp

According to your Motherboard manual that mobo supports only 2.5V DDR Dimm's (page 9). In looking around it seems that that Nanya Ram is described variously as 2.6V and 3.0V and the specs you give show 3.0 @ 200 MHz and 2.5 @ 166 MHz. Also that mobo supports DDR 333/266. By rights none of your Ram should work, but normally Ram will only work at the speed of the slowest module, in your case 133 MHz. My point is that the Ram you are using (all of it) is not appropriate for that mobo. The Nanya Ram is not being recognized probably because of the voltage requirements but thats just a guess.

From your Everest report:

Current Memory Interleave 1-Way
Supported Memory Types ECC, SDRAM
Supported Memory Voltages 3.3V
Maximum Memory Module Size 4096 MB
Memory Slots 2


In looking at the manual we know the above is wrong, something Everest is known to do (known at least to me :thumbsup:) For one thing the manual states 2GB maximum Ram and we know you have three slots.

Page 15 in the manual shows the combinations of Ram you can use in the slots.

Due to (Intel 845PE/GE/GV) chipset architecture limitation, DDR 333 memory module is only
supported when using FSB 533 Pentium 4 processor. A FSB 400 Pentium 4 processor will only
support DDR 266 memory module.


In order to get the most effective Ram for your system use the Intelฎ Processor Identification Utility as there is not enough info in that Everest report to be sure what you have. Then you can choose the proper Ram for that mobo.

Thanks Leurgy for your response.

Not happy to find out that the existing memory modules are not suitable for the mobo. When we purchase our next new PC I will certainly be looking out for this.

I assume that if we had 2 x 512MB at 333MHz that were suitable for our mobo then the computer would seem to operate faster. By the way Intel's Processor Identification Utility shows that our PC is a Pentium 4 533 MHz.

What I am now wondering is do we go for 2 x 512MB, 3 x 512 MB or 2 x 1GB for gaming purposes. I would like the PC to operate as fast as possible and not sure what RAM to add. I have found a couple so far and would really appreciate your opinion.

Also, in the mobo manual P.15 it does not list 1GB as being supported. Is this right? On same page it has a chart for the slots. We can have either 1 Double + 2 Single, or 2 Double, or 3 Single Sided DIMM's. What does this mean?

Sorry for all the question, but the more I look into this the more confused I get!

The memory I have found so far:

Kingston KVR333X64C25/512
512MB 333MHz DDR Non-ECC CL2.5 DIMM
Standard 64M X 64 Non-ECC 333MHz 184-pin Unbuffered DIMM (SDRAM-DDR, 2.5V, CL2.5, Gold)

Kingston KVR333X64C25/1G
1GB 333MHz DDR Non-ECC CL2.5 DIMM
Standard 128M X 64 Non-ECC 333MHz 184-pin Unbuffered DIMM (SDRAM-DDR, 2.5V, CL2.5, Gold)

Kingston KHX2700K2/1G
1GB Kit HyperX DDR 333MHz DIMM 2-2-2-5
Standard 64M X 64 Non-ECC 333MHz 184-pin Unbuffered DIMM (SDRAM-DDR, 2.5V, CL2, Gold)

Crucial CT6464Z335
Module Size: 512MB
Package: 184-pin DIMM
Feature: DDR PC2700
Specs: DDR PC2700 • CL=2.5 • UNBUFFERED • NON-ECC • DDR333 • 2.5V • 64Meg x 64

Crucial CT12864Z335
Module Size: 1GB
Package: 184-pin DIMM
Feature: DDR PC2700
Specs: DDR PC2700 • CL=2.5 • UNBUFFERED • NON-ECC • DDR333 • 2.5V • 128Meg x 64


Any advice you can give would be great. Thanks.

Whoever built this machine used two different types of Ram and while it obviously works its not the best performance option.

What I am now wondering is do we go for 2 x 512MB, 3 x 512 MB or 2 x 1GB for gaming purposes.


Well, obviously the 2X1GB would allow you to max out your Ram.

Also, in the mobo manual P.15 it does not list 1GB as being supported. Is this right?


That seems sort of ambiguous. That Everest report has me confused. Actually the manual states on page 9:

3 184-pin DDR DIMM sockets
— Supports DDR333/266 DIMM
— Supports only 2.5V DDR DIMM
— Supports up to 2.0GB DRAM (Max)


What I'm reading into that is that you can have a max of 2GB DRAM but 3GB DDR. Supporting only 2.5V DDR but no specs on SDRAM so I guess that why your current Ram works.

In your first post:

It doesn't seem to recognise the new RAM in 3rd slot.


This is probably because of the restrictions about what Ram can be in which slot, as in the combinations shown on page 15 concerning single sided and double sided.

RANT DIMM means Dual In Line Memory Module, which means there are chips on both sides of the Ram stick. SIMM is Single Sided In Line Memory Module with chips on one side. Yet clearly there are Single Sided DIMMS. Who's the brainiac who thought that one up? End of rant :thumbsup:

We can have either 1 Double + 2 Single, or 2 Double, or 3 Single Sided DIMM's. What does this mean?


DDR1 DDR2 DDR3
S S S
D S S
D D X
D X D
S D X
S X D

I can't make any sense out of that chart on page 15. What I think it means is that, say for the first line (S S S) is that you can use any size Ram in combination in the three slots, using one each DDR1 and DDR2 and DDR3 at the same time as long as they are single sided. The second line means you can have double sided DDR1 in one slot and single sided DDR2 in one slot and single sided DDR3 in the last slot. The third line seems to indicate you can use double sided DDR1 in one slot and double sided DDR2 in the second slot but the third slot can't be used (or you can't use DDR3?) when you have that combination, and so on. You could try calling Asus Support for the definitive answer.

If you go to Crucial.com or Kingston.com they both have "Memory Configurators". Crucial has the Crucial System Scanner and Kingston has a number of ways to determine the compatible Ram. I'd use both and go with what matches up.
