What speed is my memory running at so I can upgrad

[andyloc]

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

Why do you think it is PC2100? I never did follow that one. They're all about the same cost, just get the PC3200 that crucial recommends.

yeh I would but its just that I already have a 512Mb of PC2100 from an old PC now, so I wouldnt need to buy any if this is what the PC memory is currently running at anyway.

If I have to buy I will, but if the memory in there is at PC2100 anyways (even though it is a PC3200 stick) I will add the stcik of PC2100 I have now and save a bit money

hope you can help
thanks

Your memory is in fact running at PC 2100 speed. You should see an improvement in performance by adding the additional PC 2100 module. Wouldn't need PC 2700 or PC 3200 unless you were overclocking or had an 800 MHz FSB processor installed.
