New Rig, Time to push it!

ok i got a new gaming rig for christmas and i've push as far as i want to go and be stable for 24/7 use and a good one for benchmarking i was talking to a guy at school about how ram is labeled at a capacity but can be used far more.
Rig:
ASUS M4A78T-e Deluxe mobo
AMD Phenom II X4 955 @~ 3.5GHz for 24/7 use (hyper transport @ 2400MHz)
OCZ AMD black edition 4 gig DDR3 rated 1600MHz running @ 1800MHz
MSI Radeon HD 4890 Cyclone
1500Gig HDD space
680watt PSU

this guy from school has "4 gigs" but using the maximum memory feature of windows 7 have the operating system recognizing and using 7.5 gigs from the rated 4 gig sticks. i know it can be done and how to do it, i wanted to know if anyone has done it on OCZ and if so by how much?

 

i've not seen or heard of this being done!

But i will certainly subscribe to this post, hopefully someone else has some experience in this!

um, what?

Windows 32-bit can only address 3.5GB of RAM, there is no exceptions to this rule. Do you have a 64-bit version of Windows 7?

Also, I would love to know how to get 7.5GB out of 4GB of RAM. Maybe there is some sort of thing similar to unlocking extra cores on triple core AMD processors...but I still don't see how this would be possible with RAM.

Please elaborate.

 

could that person be talking about using a usb thumb drive or sd card as additional ram?
Windows Ready Boost

 

Thats pretty interesting, now since it uses a usb port to do this, would it work the same way with a usb ext.drive?
I'm thinking no but...

Also as stated above, W7 will only see upto 3.5gb so using the ready boost when you already have 4gb installed would seem like it wouldn't make any difference.
I may have to try this.

 

Using an external HDD is a lot slower than a flash drive. In fact, coupled with the USB it is not worth even trying. You may as well jsut use an internal hard drive instead... Hey... that's called a page file!

 

I have been playing around with an SSD external drive and even on USB it is incredibly fast so at some stage i will put it in the PC and then we should get some real performance.

These are excellent drives but not for the faint of heart when you ask "how much":eek
