16 GB (4x 4 GB) with Lynnfield CPU

btarunr · Dec 21, 2011

Has anyone tried 4x 4 GB with Core i5/i7 "Lynnfield" LGA1156 CPUs? I know for one Lynnfield IMC only supports up to 16 GB of memory, but when maxed out, is there an address-space limitation? Does graphics card memory eat into system memory "usability"?

I plan a memory upgrade, and I'll be using Windows 7 x64 Ultimate. I know that Windows 7 Home has a 16 GB address-space limitation.

Not sure about the Core i's but I am currently using 4GB x4 (16GB) with no issues with my Bulldozer setup. Before I only had 8GB (2GB x 4) with my late Phenom II setup and watching HD DivX movies my memory usage would be approx: 50% to 70%. Now with 16GB, it's around 20% to 30%. 16GB is a dump load of memory and I love it

I got my 16GB running at it's stock speed of 1866MHz... with a 4.40 GHz 8-Core Bulldozer OC all stable.

Fiancee is running a i7 860 with 16gb (4x4gb) on EVGA P55 SLi and no issues at all

Got 16GB on my i5 760.

i5 760 @ 4GHz
4x4GB @ 1600MHz Cas9

Not a single fault so far.

Yeah, no problem running 16 GB on 1156, but clocking over 1600 Mhz can be hard, and needs a good board, and supporting BIOS.

As to the IGP-included CPUs, they might eat up a bit as they would in any system, but shouldn't be too much of an issue when it comes down to accessing the rest of the ram. You got the OS covered, so I think you'll be good to go.

GART space is still just 256MB per device(sometimes for all devices), so I don't see you having any issues with included VGAs. This is only on issue on 32-bit systems where 4GB is the max addressible space. Pretty sure ultimate is liek up to 128GB? might be off on that though.
