4GB DDR3 DIMMs?

Is it just me or are there really no 4GB DDR3 dimms? What's going on with this. Now even Xeons are coming out that use DDR3. There is definitely demand for 4GB DIMM's -- I want 24GB in my i7 with 6 sticks, and I want 48GB in my new Xeon serv I'm going to be building soon.

It's been months since i7 came out, how can there still not be 4GB DDR3 dimms?

They are available but expensive. Servers use FBDIMMS which are not compatible with desktop boards.

I am waiting for these too :(

I do not want to move to i7 until i can buy good [non-overpriced] overclockable 3x4 GB personally (do not want 6x2 GB), so i might be waiting for a while :frown:

Why not?

6x2 200BCLK works perfect with a decent board and modules. :)

Eh, i've been running maxed (4 DIMMs in all slots) for so many years now, & it always adds hassle to OCing.
On every single mobo i've ever run with all slots populated, it makes things anywhere from slightly more of a PITA to way more of a PITA, going back to the A64 days till present.

If there's absolutely nothing out there for decent 3x4 GB kits when i decide i must go i7 or whatever, i might be forced to go that route.

But i've already seen how running 6x2 GB limits RAM OCing considerably vs. 3x2 GB.

And personally, i love OCing RAM...more than CPUs actually ;)

Same boat here, I'd want the option of a least easily upgrading to 24GB on my next board without tossing any RAM.

For such high capacity DIMMs, I'd be uncomfortable not having ECC even for a desktop. At least for now. 4 of them = 16GB, 6of them = 24GB.. That's huge stress on IMC and DIMMs themselves..

Granted I'd be curious to see how the following setup would perform.

- Windows 7
- 24 GB of RAM
- X25-E (32GB)

:laugh:

n7: Memory stability should be much better as Nehalem matures. Don't forget that IMC now resides in CPU. The burden is now largely on CPU rather than motherboards/chipsets, and the quality/performance of IMC is vastly superior to MCH approach.

Still, since its Intel's first attempt at IMC, it'll improve very quickly in time. Waiting to see isn't a bad idea (which is what you and I are doing).

Ideally I'd like to do a complete new build when:

Windows 7 SP1 out
Nehalem 32nm version (forgot what it's called)
Reliable 4GB modules for 16~24GB total
250GB+ SSDs in reasonable prices and consistent performance
Second-gen DX11 GPU (so that'd be GT300b/RV8x0)
