851803 2010-01-25 21:17:00 If the mobo supports more than 3 GB, then you'll still see / can use 3 GB. However it wont be running in dual channel mode. If youre using 32 bit windows, and install 2 x 2 GB, you wont be able to use all of the memory. Unless you install 64 bit windows. No, dual core is the processor / CPU, which has nothing to do with dual channel memory.

IT IS a 64bit Mb. It will support 4GB Ram. It IS running as 32 bit. I dont know if the WXP Home disc has a 64 bit option.If I do use the 64 bit, would all the existing programms on the computer run just the same?

What does dual or single channel mean to the computer, what happens? PJ

851804 2010-01-25 21:26:00 No XP Home doesnt have a 64 bit version. The only versions of Windows that support 64 bit are: XP Pro x64, Vista 64 bit, and Windows 7 64 bit.

And probably some server versions, which you dont really need. On a home computer. Most programs (that are 32 bit), will still work in 64 bit. But drivers wont. So, if you decide to install 64 bit, you HAVE to make sure whatever devices you're using, have 64 bit drivers. If they dont, it wont work

From the link I posted earlier about dual channel

Dual-channel technology was created to address the issue of bottlenecks. Increased processor speed and performance requires other, less prominent components to keep pace. In the case of dual channel design, the intended target is the memory controller, which regulates data flow between the CPU and system memory (RAM). The memory controller determines the types and speeds of RAM as well as the maximum size of each individual memory module and the overall memory capacity of the system. However, when the memory is unable to keep up with the processor, a bottleneck occurs, leaving the CPU with nothing to process. Under the single-channel architecture, any CPU with a bus speed greater than the memory speed would be susceptible to this bottleneck effect.

The dual-channel configuration alleviates the problem by doubling the amount of available memory bandwidth. Instead of a single memory channel, a second parallel channel is added. With two channels working simultaneously, the bottleneck is reduced. Rather than wait for memory technology to improve, dual-channel architecture simply takes the existing RAM technology and improves the method in which it is handled. While the actual implementation differs between Intel and AMD motherboards, the basic theory stands.

So.
Unless I change the OS to W7 I will have to stay with XP 32 bit. No problem there.

I read the link data bit don't know how that applies to me.

Still not clear on the 1 & 2GB Ram sticks. Together they are 3GB but in single channel? But this would still be better than 2GB only woulgnt it? A second new ram stick DDR2 1 or 2 GB is out of the question. I understand that to get dual channel, both ram sticks have to be the same. PJ

Yup nothing wrong with XP 32 bit. Unless you want more than 4 GB, there's no need to install 64 bit

Yup it is. At least you've got more memory

Thats right, both sticks HAVE to be identical, then you'll get dual channel

851807 2010-01-25 21:49:00 Sppeedy I think I have got there now. Thankyou for being so patient.
Since my stroke last year my brain is like a damaged HD. Damaged sectors & loss of data. I am getting to the stage where I am reading the same library books again & wondering why they seem familiar.
Thanks again. I have probably asked Metla these questions already, but I just don't remember. PJ

851809 2010-01-25 22:03:00 Next trick is to get hold of DDR/DDR1 ram for Maryann. PJ Poppa John (284)
851810 2010-01-26 05:07:00 You'll need to check Maryann's original ram card so you can match it for FSB speed as well as type and size e.g.

No, DDR ram. It's too old to support DDR2 ram. It supports DDR 200, DDR 266, or DDR 333 ram
could be any of the three depending on what CPU is fitted, these types are getting hard to find especially new (DDR400 seems easiest, and should work as well, but it probably wont match the original card, so you'd need to buy a pair to get dual channel :D).
Sorry to muddy the waters even more, PJ, maybe the ram-finder link at the top of this page will help in your efforts.

851811 2010-01-26 05:29:00 What is the difference beween DDR & DDR2? PJ

DDR1
DDR2
:p
and now DDR3

851812 2010-01-26 07:38:00 OK this is what we did. Took the side off Maryanns tin box & read the ram labels.

Max to instal is 2Gb. Has anybody got any? PJ
