Adding 4gb of ram to this system, good idea?

Hi,

I currently run 2GB (2x1) of ram (Corsair 2GB DDR2 XMS2-6400C4 TwinX) on Vista64bit, and am considering upgrading it to 6GB with an additional 4GB (2x2) of Corsair 4GB DDR2 XMS2 PC2-6400C5 TwinX (2x2GB).

The 4GB is at a very good price only ?6, though I'm aware I'd have to run my current ram at the slower timings I assume it would be a good idea to add the 4GB and I just wanted to check this?

Thanks

Tom

If its not a ddr3 board stick to 4gb instead of 6gb, you won't see much performance increase over it with 6gb.Adding 4gb of ram to this system, good idea?
With a Q6600, I'm not sure 6 gigs is necessary...
if it's ddr 2 ur wasting time 4gb is more then enough with a fast processer
Go for 4g instead of 6g. there are not much diff between 4g and 6g in gaming purpose
As you are using a Windows Vista 64-bit the minimul requirement for this operating system is 4Gb. It is best that you use the same range and brand ram on the same motherboard for max. performance. Or you have glitches.
thanks for your advice everyone, the 4GB kit though is only a few pounds more than than another 2GB of what I already have in my system, but the timings of the 4GB are slighty worse at 5-5-5-18 instead of 4-4-4-12.I just assumed that though i may not need the full 6GB it wouldn't hurt and since it was only a few pounds more than upgrading to 4GB it would be worth it.Thanks and please keep your suggestions coming
Just get the 4GB and have only that in, less headaches with issues etc.
would i really have any issues though? since it is exactly the same brand and make of ram (both Corsair DDR2 XMS2) just the 4GB runs at slightly slower timings, timings that i already know my current ram has no issue running at?Thanks again
But its not the exact same model right? Motherboard manufacturers recommend using only the exact same model. Say for example you have a 2x1GB kit and you want 4GB then they recommend another set of the same 2x1GB. You can try it but you might run into a problem, you never know you might be ok.
fair enough, and thanks again for all your help.could you also tell me what is the difference between PC2 and not? as the 4GB kit is described as being PC2-6400C5 where my current kit is just 6400C4?thanks
PC used to mean it was DDR1 but seeing as DDR1 doesnt come in pc6400 then they should be the same. Just different stores etc put it differently.
thanks, its the same store but i see what you mean, so no problem there then.
