Boot issues and RAM Not Showing up in Windows XP

[jazzman77]

Hello,

I initially had trouble booting, then I added 1 stick at a time. WIll this be an issue in the future?
When I boot it shows 6GB of RAM in the boot settings, but in Windows it only shows 3GB RAM
I did not change anything in the BIOS.. What do I need to change the BIOS to?

Also will 1066 RAM give me much better performance for NLE Editing?

Thanks!

Dave

Due to the limitations of the operating system you will only see 3gb or less when you enter Windows. In order to utilize, or "see" more then 3 you will need to upgrade to a OS with 64 bit architecture, ie Windows Vista x64, Windows 7 x64. I am not quite sure how XP x64 handles the memory limatition. If you are on a 64 bit OS make sure Memory Remap is enabled in the BIOS, if the setting is there!

You won't be able to run DDR2-1066 with your CPU and motherboard combination.

Thank you

Thanks here is something strange. I already had the 2 x 1 gb dual channel sticks installed and I installed windows 7.
I went to install the 2 2 GB single channel sticks and the PC would not boot. I took one out and it did boot, but on boot up it showed 4GB RAM but listed it as DDR2 667 Single Channel. All three sticks are DDR2 800 IS the RAM defective or do I need to change a setting. Also, I dont see memory remap on the setup of the mobo. Can you please help? THANKS

put the 2x2gb sticks in slot 1 and 2 for 4gb, yet it will only be single channel, make sure the memory is set to 800 in the BIOS, if you attempt to run a combination of those sticks Im quite sure it will default to single channel because its gonna read the lesser of the installed memory

Dual Channel mode cannot be enabled if only one DDR2 memory module is installed

dont worry about the memory remapping

Inastalled RAM PC No Longer Boots

Hello I installed the 2 x 2 GB in bank 0 and the pc no longer boots Hopefully gskill support can help me ???defective

Thanks for your response

does it boot using 1 2gb stick at a time? another suggestion is to just replace them as you had in your first post

[jazzman77]

Strange results

Thanks for the advice. I put in the the first 2GB stick on the red bank - system says 2GB 800 64 bit

Put in the second 2GB single channel stick - system says 4GB Dual Channel 800 128 bit ???


Put in the 2 1Gb Dual Channel sticks - System Say 6GB 667 Dual Channel 128 bit

Huh???? All of the sticks are 800's

Thanks in advance!

Yep, one stick single channel is 64bit. Two sticks dual channel makes 128bit. That's why it is always better to utilize your motherboard's designed memory architecture for optimum performance.

Hi Jazzman,

I don't know if this is the case with your mobo, but I have an MSI mobo that supports 8GB max, and when I populate it fully, BIOS shows 667 dual-channel during boot.

I asked about this on MSI forums, and they said that this is normal, at least for MSI mobos, and gave me some links:

So maybe your mobo has the same situation. I kind of think that it's some kind of limitation of the onboard memory controllers on the AMD CPUs (I have an AMD X2 5200... almost the same as yours)...

Some motherboards do automatically downclock when operating maximum memory capacity. This is especially so with pre-built computers such as Dell, HP, etc. systems and laptops.
