Trying to choose DDR-III Memory Modules for 32 GB RAM (4 * 8 GB)

[xdan]

Curiously enough, the closest thing I saw at 8 GB modules are these two Crucial BallistiX modules, BLT8G3D1608ET3LX0 (1600 MHz 8-8-8-24 1.35V) and BLS8G3D1609ES2LX0 (1600 MHz 9-9-9-24 1.35V) that seems comparable to the Samsung Green, but I have no references if they are good or not.

I friend has this kit on Intel IB, 4*8GB, they can do 2133 CL 10-10-10-27 1.6v and 2133 CL 9-10-10-27 about 1.65v.
Up to 1.65v it's safe, but at 100% load they heat up quite good, for intense usage a memory cooler will be good.
Not sure how they work on Athlon X4 but on Vishera see under...

Stay away from any modules based on Micron ICs (Crucial is Micron).
Their ICs do no work properly on any AMD IMC since 12h.

For 15h parts (Kaveri, Richland, Trinity, Vishera, Zambezi) you want either Hynix or Samsung based modules.
KHX16LC9K2/16X for example is always based on 1.35V Hynix MFR variant.

You base your information on what?
Have you check the new 4GB/8GB modules using new chips : D9PFJ, D9QMS, D9QMT, D9OBJ?

I had Tactical LP 1600CL8 1.35v 4GB on Vishera, FX 8320+ Sabertooth 990FX rev.1
D9QMT chips.
Worked better than any other memory, even some PSC was har to stabilise at 2400.
2400 CL 10-10-10-24 1.6v Memtest stable.
Hynix CFR at least with Vishera doesn't work well, a 2666C11 Corsair kit merely did 2400.

Now on 8GB modules 1600CL8 are other chips than on 4GB, but still Micron, have same comportament only they stop at 2200.

Crucial memory at high capacity it's quite cheap and good performance.
