Can i use this Ram configuration ?

Hi
I have p4 2.4 Ghz based system having 256 ddr1 Ram 266 mhz
I m interested in upgrading my Ram so
Can i connect 512 ddr1 333 mhz with my current 256 ddr1 266 mhz ?
My mobo supports both 266 and 333 mhz frequency

yes but i suggest use DDR2

yes you can but it will run at 266mhz.

u can go for 512 ddr1 400 mhz

how can a DDR1 mobo will support DDR2 ???

even after going for 400 it will run for 266 MHz only ....and he said his mobo supports 266 and 333 only ...

A

ingame2 is correct.
and there is nothing like dual channel in older mobos. I ran well 256MB and 128MB on 845 mobo.

though I am not prety sure what will happen with 333MHz with 266MHz, I do not hink FSB will be lowered.

Yes, you can run both the RAM simultaneously. As somebody here said both RAM will run at the slower speed, i.e 266Mhz. You may however wanna test it first. Some RAM timings may or may not match. In the later case it may lead to crashes.

No need to worry as i already do this wit my old mobo... Its supports upto 333MHz and i had a 333MHz 256MB RAM on 1st slot and 400MHz 512MB RAM in second slot. The latter was run on 333MHz freq and no crashing is there.... The system is still running in friends home...

I think his mobo supports DDR1 not 2!!!!!!!!!!!!!!!!

The speed of the 333MHz RAM will be tuned down to 266MHz.

Same case with me here, only mine was 333MHz and 400MHz case.

Wrong, it will run at 333Mhz,and putting 400mhz 1 stick will make sure it will always run at 333mhz

imgame2 is saying that if he uses both 266 and 400 Mhz sticks then the 400 one will run at 266Mhz

it is only if he removes the 256 one and install single 400 Mhz one the freq will be 333Mhz

mixing different frequencies is not recommended,single stick 512mb 333mhz will perform better than 768mb 266mhz
