I am very very confused.

I have a MSI 7046 motheboard, it is a 3.06GHz Pentiunm 4 with a 533MHz FSB. 512Mb RAM

I want to add another 512Mb RAM to my PC.

I have used PCwizard, Everest, and the Crucial scan tool, and looked in Bios and it says PC3200

Is the current RAM in my PC running at PC3200? or is it running at the slower PC2100 (or even PC2700).

The reason I ask is that I have a spare 512Mb stick of PC2100 in a old PC, I didnt want to put it in as thought it would slow down too much and not match the bus speeds or whatever.

Can someone please help, what speed is the factory built memory running at?

if you download CPUz (http://www.cpuid.com/cpuz.php) This is what it states on the memory page (sorry cant find how to insert an image)

Frequency: 133MHz
FSB:DRAM 1:1

on the CPU page it states
Core SPeed 3059MHz
Multiplier x23
FSB 133MHz
Bus Speed 532MHz

If the current 512Mb speed is only running at PC2100 (although the actual stick can run at PC3200) I may as well use the stick I have and not have to buy another one.

Basic question is: what speed is the current 512Mb stick inside running? PC2100,PC2700 or PC3200?

If its at it full speed of PC3200 then I need to buy anohter one, if its running at PC2100 beacuse of the speed of the FSB anyway, I will install my spre PC2100.

hope someone can put me out of my misery
thanks
Andy

Your motherboard would just underclock the PC3200 RAM. As long as you match the pin set on your RAM you're probably fine. My friend has PC2700 and PC3200 in his gaming rig and there's no problems.

In general, always try and match your RAM sticks as closely as possible. I always try to match them down to the part number that the manufacturer uses - and rarely have memory problems (until I stick my fat fingers inside the case!).

I've have used unmatched RAM once or twice in the past without any major problems - so it may not be a critical issue. But, as I've said in other posts...Do you want to have an error while your balancing your checkbook? Or do you want an error while you're ordering that hard drive - and the quantity field auto-fills with 10,000 rather than a 1? Whatcha gonna do with 10,000 hard drives?

Some may say I'm anal about memory - I prefer the term prudent! :thumbsup:
