24GB Memory Concerns

Hello, I have been looking at upgrading my computer recently, and with how cheap memory is these days I was thinking about getting 24GB (6x4gb) of memory and trying to make a ram disk out of part of it to move my page file to. After reading up on some forums I have noticed people saying some strange things I didn't know about memory, for example someone said "remember in a two module per channel configuration anything over 1066 is overclocking the memory controller." Right now I am running 3x2GB in my computer at 1600 and I had planned to run the 24GB at 1600 also but is this not possible? Is it ok to have it spread across all the memory slots or do I need to condense it down to 3? My motherboard in case anyone needs to know is an Asus P6X58D Premium. Thanks!
 
Remember that the 45nm lga1366 processors officially support DDR3 1066 maximum.

Anything more than DDR3 1066 is an overclock of your memory controller on the CPU. DDR3 1600 is an easy overclock to achieve if you only populate 3 slots. If you populate all 6 slots it may be a little harder but still very possible. It may just work. Remember with all forms of overclocking your mileage will vary because no two cpus are exactly alike. Its also possible that you would have to up your IMC voltage to get this memory controller overclock to work. To me your question is like "If I buy an i5 2500K am I going to be able to run it at 4.5 GHz stable?"

If you are unlucky and can not get it to work at DDR3 1600 the same memory modules will almost certainly work at DDR3 1333. Remember memory modules support lower speeds then their rating.

Depends on how much you are overclocking the cpu.

I ran 24gb at 1600 and it was fine. I ran the 950 @ 4.0 ghz. Although, I noticed temps where higher than normal. So your OC ceiling might be lower. The board was an Asus p6t deluxe v1

That defeats the reason for having a page file in the first place. Although some applications will want a page file even though it is not needed.

I am not worried about running out of ram because 24 gigs is significantly more than I should ever use on my current system. Moving the page file to ram will simply make it operate as fast as normal memory. I would disable it but there are still some applications that require a page file to operate properly.

Currently I have an Intel Core i7 920 overclocked to 4GHz completely stable for 2+ years, so hopefully it won't have problems with the increased memory because the performance I have gotten out of this thing is amazing for what I paid for the chip. Also because of the way it is overclocked my memory is actually running at 1601MHz.
 
Forcing the page file into system memory is absolutely counter-intuitive. Windows pages to disk to free memory; why would you want to preemptively reduce your available memory and cause more frequent paging?

There's also file cache, as your set of applications aren't the only thing occupying memory. With this, Windows will cache files for improved performance. With less available memory, do you see where this is heading?

Meh, whatever then I am getting OCz Agility 3 SSD's too so paging will be fast anyway even without moving it. So should I go to 24 gigs of memory and just have a lot of room for expansion or cut it off at 12 so as to not risk having to change my overclock? Just a side note too, I use 3.13 gigs of memory on my system with just start up software and firefox running (which I restart sometimes but almost always have open) so I actually use my full 6 gigs of ram quite frequently right now.
 
If how you use the system demands more memory, then the overclock shouldn't take precedence. That said, the extra DIMMs may or may not affect the overclock. There's lots of factors at play, and your best bet is to just try it.

I won't belittle you and tell you 12 gigs is enough. :)

What applications are you doing that eats up 6gb of RAM? I can have two simultaneous 2-D comsol flow modeling running and not exceed 5.5gb RAM, with firefox running.

Honestly it will work better if you just make a really small page file on disk, but whatever.
 
Sorry to revive an old thread but I upgraded my memory and I did end up going to 24 gigs. Detecting all 24 gigs at 1600 stable for the past couple weeks so yes it can be done. Oh ya and I still have my i7 920 stable overclocked to 4GHz. Thanks!
 
I had 24gb of RAM at 1600 mhz stable for the past 2 months, that is until one of the RAM sticks went bad. And I had my 920 clocked to 4.2 ghz.
