Well I'm a bit of a newb when it comes to overclocking, but currently running my E5200 at 3GHz with the RAM at 900MHz.

Here's the CPU-Z screen;

It generally doesn't pass 60c on full load and stays at around 45c idle. What I'm wondering is what can be improved? Like, to increase the RAM speed but keep my current cpu clock (or increase it slightly).

Thanks for the help. :)
 
If your memory is rated at 1066 you could play around with the FSB:RAM ratio and FSB to bring the RAM up to speed. Are you using the stock cooler? If you got a new HSF you could probably reduce those temps and push the chip further by increasing the vcore. I've got my E5200 at 3.6Ghz (vcore 1.392,30c idle,50c load with Freezer Pro) but some of the guys on here are hitting 4Ghz+, it depends on the chip :)

The RAM is rated at 800.

Yeah I'm using the stock cooler for now. Hopefully next week I'll be ordering a new HSF so I would be looking to increase the speed to 3.6 atleast. :) Just to clarify something though, what's the advantage to using a high FSB and low multiplier, or a low FSB and a high multiplier?

Increasing the multiplier will only increase the CPU speed, increasing the FSB will increase the CPU and RAM speed. So you may find if you increase your FSB further the RAM will become unstable, so you would need to either adjust the FSB:RAM ratio or adjust the multiplier rather than the FSB. Its a case of finding a balance to get the maximum stable CPU and RAM.

A good way to do it is to drop the RAM speed down using the FSB:RAM strap, then find out what your max stable CPU speed is, then drop the multiplier down and find out what your max stable RAM speed is, if you try to increase both together its hard to tell if its your CPU or memory that is holding you back. I found the sticky here is really helpful explaining this.

In a case where you had 2 set ups with exactly the same CPU and RAM speed but with one with high FSB and low multiplier, and another with low FSB and a high multiplier, I don't know which would be better, any of the more experience guys know? My guess would be it doesn't make a massive difference.

To run you ram as dual channel you will need 2 identical sticks of RAM, and have them in the correct slots on your board (so long as your board supports dual channel which most do), usually its slots 1 and 3 or 2 and 4, but check your manual. I don't know much about timings but I think there is a sticky in the memory section which explains what the timings do. Hope this helps.
 
High FSB low multiplier should generally be a bit quicker, as the FSB controls the rate at which data can be transferred to the CPU.
 
High FSB is not really possible on these CPU's gets hard anything over 300, have had a good play with mine.
 
It's probably single channel as my mATX mobo only has 2 memory slots.

Having a quick skim over that guide, it looks like it will help a lot. Once I get that cooler, I'll push the cpu further and report back if I come across any issues. :)

Thanks.
