Ok so Installing RAM is easy.

Trouble is I am a little slow on the uptake. I have been trying to get my head around it all now for a day so I can buy a new 1GB stick of Memory to add to my 512MB I already have. But with all the MHz and PC2700 blah blah blah my head is aching. So can someone please HELP!!!!

What MHz do i need etc and all the info i need to buy a new stick online.
I know next to nothing about what you guys might need to tell me what i need, so here is as much info as I can find about my system.

Intel D845EBG2
Maximum Memory Capacity 2048MB
Current 512MB
Avaliable slots 1
Number of banks 2
Dual Channel Support : No
CPU manufacturer: Genuineintel
CPU family- intel pentium 4 2.80ghz, model 2, stepping 7
CPU speed 2800Mhz
Current memory : DDR PC2300 (DDR266)
System Bus Speed 533MHz
System Memory Speed 266MHz

I have been told DDR PC3200/2700 and 4000 would work but I dont understand the differences. I am going to add the new memory to my existing one.

Any help on this matter will be much appreciated

The differences (from what I understand) are that they opperate at different speeds. The more MHz you have the faster the RAM can be accessed. I would go with the same MHz you have in it now (PC3200), because, if I remember right, if you have more than 1 stick you need to have them at least at the same MHz..

Crucial will tell you all the options you have. When it comes to memory, you can't beat it.

Well I don't really know much about this stuff, but I'll try to help. You were probably told you can use pc 2700 and 3200 because these are different types of ddr ram. I would suggest still getting ram that runs at 266 mhz (pc2100) just to be on the safe side. Oh and the Mhz value is the speed the ram runs at, but I guess that doesn't make that much of a difference. Hopefully someone who knows more about this stuff will help you. :thumbsup:

Remove your old stick and look what the details are on it and get a gig stick with the same spec, you cant go wrong then. www.ebuyer.com have been good for me in the past with prices and delivery.

So silly question. But my system memory speed of 266MHz is the maximum that the memory can run at. So there is little or no point in getting a memory stick with say 400MHz for example. Sorry about the lame questions but I am stuggling to understand.

Have looked on my memory stick and there is no sticky lable with the specs. Got most of my info from Crucial.com ( they were a great help) but it is the MHz i am stuggling to understand and they couldnt tell me that.

You guys are being a great help though.


Also it is ok to mix and match my current DDR PC2300 with other types? Say PC2700 aslong and the MHZ are the same and they are both DDR?? is that right? do they have to be in any order in the slots?

Many thanks You guys

Here's a link to the Intel FAQ's for your mobo - just scroll down to the memory section: http://www.intel.com/support/motherboards/...b/cs-008635.htm

FWIW - I like using the Crucial memory configurator for several reasons:
1) They give a lifetime warranty (so, in effect, the configurator is guarantee'd to be correct)
2) They have reasonable prices
3) They include installation instructions with each memory shipment
4) Their service and support is fantastic. I sent memory to my son - which was lost by UPS. They resent the memory immediately - before the UPS investigation was done.

I don't think so. I'd have to check but in this hardware class I'm taking I am pretty sure we learned that you can't mix RAM, because it will just recognize the higher frequency RAM and not the lower. I might be wrong, but I'll look it up tommorow and let ya know for sure..

I think that you can put in the higher speed ram but it will only be as fast as the slowest that you have installed.

Yeah, that's right! So he would probably just be better off buying the slower speed, or upgrading both..

That's correct, lets sya your motherboard can use PC2700 and PC3200, and there's currently 1, 512MB stick installed, and then you decided to put in another 512MB stick, but it's PC 3200, the PC3200 will underclock to the PC2700's speed.

You'll have to compare the specification set forth in the motherboard manual with the specifications for both sets of RAM to get an idea if this will work.

Generally most common stuff will work - but there are enough inconsistencies that it's advisable to check it out first.
