2x8 (later 4x8) on Crosshair V Formula 990FX

Looking to upgrade my RAM due to VM limitations when heavily taxing the PC.

The manual is confusing - says it can support up to 32gb, but also that you can use up to 4gb sticks (in the memory-specific section of the manual).

Can anyone confirm this will run with 8gb sticks?

Motherboard manufacturers tend to lie somewhat about memory capacity and speed configurations. I would email ASUS and ask them specifically which memory they used for 32GB and also what CPU they used. The QVL testing is shady like that.

The answer might be something like "4x8GB of XXX model memory running at DDR3-1333 9-9-9-30 2T only on specific FX CPU"

Already done that a week ago, still got no answer.

I looked up the ASUS CH5 and its QVL list. They do claim in the mobo specs to support 32GB, but they have only tested up to 4GB sticks in the QVL.

Then I checked a few of the major memory brands, for their specific QVL's referenced to the CH5, and the maximum supported I found was 16GB, although Corsair does recommend some 2x8GB kits for that motherboard.

Team has some 32GB memory that they have tested with some other AM3+ motherboards (with a Phenom II 955???)

So,

It might work.

It might work at lower RAM speed/loose timing

It might not work at all.

I would say your best bet is to bother ASUS, Corsair, and Team until they can give you a definitive answer, because a 32GB kit is expensive.

yeah, that was my confusion too (the total 32gb but only 4gb sticks supported).

asus haven't responded.

I'm gonna go with a 2x8gb kit at first to see if that works, and if it does then down the line just add another one.
gonna buy it locally and not off newegg, spoke to the retailer and i can return it if it doesn't work (refund or just get a 4x4 kit instead)
