My G4 466 graphite won't see my low density 512mb sdram stick!

Hi - i have a latter G4 466 model G4 and need to install 1gb of ram so i bought 512mb low density ram for it (specified as compatible by the vendor) but it doesn't show up. Is there a firmware upgrade i can do to get the computer to see it? Please help - best regards Russ Pay

    Hi - tried that before anything else! I have 3 sticks - so the chances are the seller gave me the wrong memory.
    I'm sending it back, which is very inconvenient and i am cross as i specified exactly what i needed it for!

As long as the 512MB RAM chip is running at 133Mhz it should work, it may have compatibility issues with the other RAM in the unit. Try removing the other RAM first if it does not work after that you probably have a faulty piece of memory.

Bah! That is just cra-zy!

Maximum TOTAL Amount is 2GigaByte. (2GB)
Maximum Amount for EACH ram memory slot is 1GB.

IF, you only have ONE ram memory module ('Stick'), it goes in Slot 1. (DIMM 1)
That is the ram memory slot closest to the processor socket.
The Processor reads ram memory Slot 1 first.

Installed Ram, now wont boot with the new ram? Put old Ram, starts fine?


The new RAM is either faulty or incompatible (not the correct type).
For larger RAM use the same make and type as the old RAM

Hi guys, i have installed 2 sdrams pc-133 512mb,together 1gb, but yhe bios and the system shows me only the half memory,whyyyyyyyy


Are you sure that both sticks of RAM are properly "seated"?

How much memory is found when only one stick is used?
How much memory is found when only the other stick is used?

Which motherboard? Some very-old motherboards only support a maximum of 256MB per slot.

How many memory-chips are on each stick of RAM?
If you have purchased "high-density" memory (small number of memory-chips),
and your motherboard only supports "low-density" memory, then only 1/2 or 1/4 of the actual RAM will be used.

Hi everybody, I have a problem installing a dimm SDRAM Module on a MoBo Syntax SVX 400. User Manual says that till 4GB modules are supported. I bought a Transcend 1GB PC266 SDRAM module to increase the...


One long beep signals a memory failure - the stick you just bought is faulty. BTW there is no PC266 in SDRAM the maximum is PC133. PC266 is the first standard that appeared for DDRAM. so you most likely have bought something not right from the start.

Unit came with 2 256 mem sticks--bought and installed 2 1GB sticks(pc3200,400mhz,84pin,low density,DDR--unit will not boot


The 2 1Gb RAM are either the wrong type or they are incompatible.
Try to use the same brand and speed as the 256 Mb RAM that was installed in your Dell.

RAM Slot does not recognize more than 512MB ( 184 )


Consider updating your motherboard bios.

http://www.asrock.com/mb/download.asp?Model=K7VT2&o=BIOS

Also make sure that your memory is correct for this system:


- Max. capacity of system memory: 2GB DDR or 2GB SDRAM
- DDR x 2, DDR266/200 non-ECC, un-buffered memory
- SDRAM x 2, PC133/100 non-ECC, un-buffered memory

I need to buy memory for my computer its an emachines desktop model# T3410 512 MB DDR SDRAM and I dont know what to get


in DDR ram there is some models like ddr and ddr2 and another new model is DDR3. First you check what is your ram related to. for that in some pcs bios option system information the details are there. For that at the time of booting before windows logo press the button whatever is showing to enter setup. and check otherwise remove your ram and take that to a computer shop and take a new ram with same model.

And one more thing is you have to check your clock speed of your ram. Remove your ram from pc and check if any information is there on ram

2G Memory Upgrade


I had similar problem with CORSAIR XMS2 2GB (2 x 1GB) 240-Pin DDR2 SDRAM DDR2 800 (PC2 6400) Dual Channel Kit Desktop Memory

If this is your RAM:
Corsair 1024MB Value Select PC2-4200 (533MHz) DDR2 RAM, 128Mx64non-ECC, 240-pin DIMM, Unbuffered, CL4, Lifetime warranty (VS1GB533D2) Then it is high density. You need low density to work, look for one ending with an 8, not 64.

2 x 1GB Samsung PC2100 appearing as just 1GB (2 X 512MB)


Hi Patrick,
I see you're point. I know this, you can not run "more than" 512MB in any DIMM slot. That is shown at the bottom of page 10 & the top of page 11. You can not run both types of memory at the same time, even though the chart looks like you could. The description term on page 10, states; Users only can install either 168-pin SDRAM Module or 184-pin DDR DRAM Module at one time. (You can't run both). You can run 4x512MB in all banks using184-pin DDR SDRAM. Or you can run 4x512MB in all banks of 168-pin SDRAMs. Total of 2GB.
So you can not run 1GB of memory in any bank.
