Hi, iv just got some new RAM 8gig @800MHz timmings 4-4-4-12 @2.1v 4x2gig chips

this is upgraded from 3gig @800MHz timmings 5-5-5-15 3x1gig chips

how do i know if they are running in dual channel mode?

If you have all four DIMMs filled they will run dual by default.

if there identical chips they WILL be running dual channel as you have filled all of your ram slots, if it was 2x4gb then you would have to place them in the corresponding slots. ie: 1,3 or 1,2 dependant on board

congrats, your epenis just grew another 6 inches with that 8gb ram :laugh:

thanks everyone, i found it, it is running in dual

btw anyone got any ideas why im finding that with 8GB @800 timming 4-4-4-12 i am not getting better performance than

3GB none dual @ 800 timmings 5-5-5-15????

i get lower Vista rating too?

Because barely any applications make use of 8 GB of ram so a performance boost isn't going to be too noticeable and your latencies are not dramatically lower either. I'd recommend that you disable virtual memory completely and you should notice an improvement.

TY, any idea about what timings would be good to go for?

and i changed VM to min 16MB max 400MB just to keep info about any crashes, is this worth doing or should i just remove them all together?

Remove virtual memory completely on all hard disk drives. The hard disk's virtual memory is more than 100 times slower than RAM, so keep VM disabled.

There is no quick fix to memory timings you have to experiment and it could take a few hours. Try every single latency combination in the bios and write down the combinations that work and eventually you will have a list of low timings e.g. first try 5-4-5-15, then 5-4-4-15, and then 5-4-4-12 and then 4-4-4-12 and so on.

If you select an incompatible timing you may have to reset your bios via jumper pin and start again.
