using two different company RAMs

It is not like that. The reason we check timings and speeds before upgrading RAM, so it runs at optimized levels. If OC is being done, this is a highly critical factor. If it will be just plug-and-play then no need to check, the board should support.

But why would you want one RAM to run slower -- might as well purchase to match them up. System would probably not be unstable if RAMs are mismatched.

I've used one 128 MB 100 mhz and other 128 MB 133 Mhz together in my PIII MB intel chipset 810e with PIII CPU 1.13 Ghz. I had 64 MB 100 mhz too I changed alternately but I found no problem I found total 256 or 192 MB RAM Full shown in system properties. SO it shouldn't be any problem. :) All purchased separately 2nd hand without looking at brand.

Oh no..I don't wanna buy 2 different speed RAMs.I didn't know there was a difference while overclocking & just simply plugging it.Ok now it makes sense..I mean you would need same latencies while overclocking but not necessary for non-overclockers.Like I have a 2GB DDR3 Zion 1333MHz RAM & I wanna buy another 2GB stick like Corsair or G-Skill.I know I wont overclock so I can simply buy a 1333MHz DDR3 RAM & plug it in my system.

You shall be fine.

  • Ok then while buying ram should i also check that cas latency and timings or is it enough to check that PC2-6400 thing?
  • The latency thing changes while overclocking know?bcoz when i overclocked my processor cas latency changed from 5-5-5-15 to 6-6-6-18.then whats the use of checking latency?
  • Another thing my board supports just 667 and 800 MHZ ram then the frequency of the ram should be 400,but when i overclocked my processor it gone to 440.how is this possible motherboard should have damaged know? or does the board supports more frequency than mentioned?

No the board will not get damaged. At time a slight OC can bump up RAM speed, but it should be fine, as long as the board is fine and temperatures are low.

Should be fine.

EDIT:
Sorry misread it. No you cannot. Max you can go till is 800Mhz.

^^ the ram that gets its clock kicked up when you raise the processor bus speed is stretched. its a value ram & your board isn't a OC board. so either you'll get BSOD or some kind of error when you insert ram of higher speed that your board officially doesn't support. or the new ram will be clocked down to 800Mhz,

True, but running it at 1033Mhz will cause issues. It will never run at those speed, since the board does not permit it.

your board support 667/800Mhz ram doesn't mean your board will run ram at exactly 800Mhz. theres always some small tolerance level. you can upp the clock of the ram a bit (by OC the processor) but 1066Mhz is a different standard. your board may support it but its not officially supported. so expect errors or unstable system.

guys yesterday i went to a shop to buy the 2GB RAM and i told that i want a DDR 2 800MHz RAM and i mentioned that PC2-6400, maximum band width 400MHz as shown by cpu-z and(also as mentioned by asing about that pc2-6400) then he asked me do i need 667 MHz RAM then i told him i want a 800 MHz RAM and my board supports 800MHz so he asked me then why that software shows 400MHz and said there must be something problem in that RAM.Is he telling correctly that my RAM is not working correctly?if not then why do it shows 400MHz though the RAM is 800?
Here is the cpu-z pic.

Hey whats that widget that u r using in d sidebar showing cpu stats?

N yes,its 400*2=800.
