Can I mix DDR memory ?

  sonaisali 22:48 22 Jan 2004

I have an A7V333 socket A motherboard which says it will accept DDR RAm PC1600/ PC2100 and PC2700.
I currently have 512mb of PC2100 in my machine. If I wanted to add to this do I have to purchase more PC2100 or can I buy PC2700 and mix it ?

You can mix diffrerent speeds of RAM,but if you buy faster RAM than the stuff you already have,it will continue to operate at the speed of your slowest RAM.Also note,mixing RAM speeds or even mfg's can lead to instability,and the errors it can create can be nigh on impossible to trace.

DDR PC3200 which i noticed after searching out ram info for the same motherboard.

"If" be it the case,it may overcome the problem with installing three PC2700 modules? which i was un aware off when my system was purchased.

Info from the update spec sheet on the A7V333 MB manual.

If you go to the Motherboard Info (bottom of page)the spec still only states for DDR SDRAM Frequencies PC1600, PC2100, and PC2700, so do check it out if you were thinking of the DDR PC3200 Not often Crucial would be wrong?

Important information about your system
If three PC2700 modules are used, the system will only run at 266MHz.

You can instal DDR memory in any size, speed, etc. as long as it is in pairs.

It is always preferable to use the same manufacturer for ALL memory.

If your motherboard states that PC2700 as maximum speed, then you can fit any speed i.e. PC2100, PC2700, PC3200 or even PC4000 (again in pairs) but it will not run any faster than PC2700, so you would be wasting your money.

As Chegs ® states the motherboard will run at the speed of the slowest pair.

So, if you have PC2700 fitted go for PC2700 and try the site JIM quotes.

Thanks Guy's. now sorted

However, if you plan to upgrade your mobo etc in the near future then getting the faster memory wouldn't be wasting money.

Is the manufacturer really that important? i would have said as long as it was same type and speed it would be OK.
