Memory question

[cornelio]

Hi,

I am using DDR2667 on my current motherboard and this motherboard can use DDR2800. I can adjust the memory speed manually and my question is if I use DDR2800 memory will it speed up performance and if it will overclock the PCIe and PCI bus. My PC specs are on my sig.

Any help appreciated.

It's true, you can adjust your memory settings.
But you'd be pushing your DDR2-667 beyonds it's rated speed.
The memory may or may not run stable at that speed.
The memory would probably need extra voltage applied in order to achieve stability at that speed.
The extra voltage would likely decrease the life of the memory.

Even if all the memory stars were aligned...
You wouldn't notice any performance increase at all.

Thanks for the reply. What I actually meant is to install DDR2800 memory and put it on the motherboard (It accepts up to DDR2800) but it seems it is better to upgrade to a faster motherboard and DDR3 memory judging from your response.

Thanks again.

Yes, simply moving from DDR2-667 to DDR2-800, you wouldn't notice any performance increase.
You'd likely be able to squeeze out some tiny increase in benchmarks.
But back in the real world it would be the same machine as before.
