hello i dont know how much stupid this question is but still i have ask
i have a transcend 4gb ddr3 1333 ram (JM1333KLN-4G) which offers bus speed 333 (1333/4)
which is needed for my intel core2duo e8400 its all running on my msi g41m p33 combo motherbord
i would like to know should i insert additional ddr2 ram with fsb 800 as it offers bus speed of 400 (800/2) which is required for overclocking my cpu (FYI c2d 8400 has a locked multiplier ie 9x with a bus speed of 333 which translate into 3GHz)
i know putting ddr3 and ddr2 ram on a mobo can make my pc go wild
but still i wolud like to know the possibility

You cant mix DDR2 and DDR3 they are different. Boards that support both types of RAM only support one at a time. The e8400 is very old now, I wouldnt worry about overclocking it as the gains won't be great.
If you need to overclock then you can try reducing the RAM timings (look for CAS or CAT Latency in the bios) bigger numbers = reduced timings = more latency (I know, a bit weird) you will often find that changing the settings from eg 9/9/9/21 to say 11/11/11/25 will allow it to run at a faster FSB. A little extra voltage on the RAM will also help if you know what you're doing. I think you might want to look at a newer system though, this is pretty old now

msi g41m p33 combo has 4 slots 2XDDR2 and 2XDDR3 support max upto 8gb and in my bios i have max timings of 10/10/10etc and max dram frequency of 1333 when i try to low my dramf and increase timing pc dosent boot may be you can help a bit

No, additional RAM will actually makes it harder to overclock. If it defaults to 1066 it could be that 1333 is already pushing it past what the motherboard is capable of running it at anyway hence why you cant hit 1600http://www.msi.com/product/mb/G41MP33_Combo.html#hero-s...
sorry i dint give you enough info at first but 1066 is default but it can be pushed to 1333 which i guess is maxed supported by my mobo it is also mentioned on msi website
that's why i want to put a ddr2 800

You might not be overclocking the RAM but you are overclocking the controller. Its not "stupid" thats just what it supports. 1333 is technically pushing it out of spectrum, which is likely why it wont go to the 1600. You would be better pulling the divider down lower so the ram runs SLOWER than 1333 if you want to overclock via the FSB

i am not getting how going below 1333 will help me overclock because buss speed is calculated by dividing dram frequency with 4 for ddr3 ram i.e 1333/4=333

You see that *(OC) that means you are overclocking by going to that setting. The board supports 1066, 1333 is an O(ver)C(lock)
You dont quite understand how the dram frequency works either, you are correct about DDR3 being FSB*4 but you need to LOWER it to overclock -
If you put the FSB to 400 the DRAM will try to run at 1600 and the machine will not boot.
You need to alter the RAM divider so that the DRAM speed is less that 1066, then boost the FSB by a small amount so the CPU runs faster.
I think you need to read up on the subject a bit more if you are having problems

You should stay with its max normal speed, 1066MHz, is safer for your PC. OCing the memory controller is not as stable as CPUs.i am not overclocking my ram its actually support 1333 its the stupid mobo putting it down to 1066
Yes, the MoBo put it down because the memory controller don't support 1333MHz natively. In the MoBo specs at MSI it clearly say 1333MHz is OC.

dude my pc dosent even boot if I increase the base clock to 343
you are right to go to 400 FSB i would required a 1600 but the max my mobo can support is 1333
so the only option i have is to go with ddr2 800 as with ddr2 memory the (base clock= FSB / 2)

Then that is the max overclock, congratulations. If you boost the VCore it might go a little furtherthere is only VTT NB and DRAM voltage i dont have access to VCore
i have tried everything even max out all the voltage but couldn't go above 342 on c2d
note with my old intel p4 processor i have overclocked it from 3.2 to 4.2 on this mobo and ram

drop your ram speed to the lowest it will go, for that board should be 800mhz. Leave your cpu at stock speed and boot the computer up to make sure everything is ok.
Before doing anything make sure you have a good aftermarket cooler. Max vcor for the core2duo e8400 that I could find was 1.4v so don't go past that. stock settings are 9x333 for the cpu so bump it up to 9x334 and boot the computer up, if it boots up good, run intel burn test and watch temp reading with coretemp. If everything passes then reboot the computer and bump to 335, if it boots repeat test. Repeat this till the computer wont boot. Most likely if the computer wont boot you will have to reset the cmos to get back into the bios, once back into the bios reset the FSB back to where you had left off and bump the vcor up .01-.02volts and try to boot the computer. Keep dong this till you get unsafe temps or run out of voltage ( remember to not go over 1.4v) once you find the limit of the cpu you can then start playing with the ram to see what the highest speed you can get out of it.

this mobo does not let us to adjust VCore

The motherboard is not designed for overclocking, you will not be able to overclock any further without voltage controlyou guys sure that its due to voltage and not limited base clock due to 1333 ram???
because i see my vcore is just 1.1-2 and when i overclock cpu to 342 it automatically up the voltage to 1.27
so i am guessing it automatically adjust the voltage as required
