Not that I know of. FYI pairing memory modules that are not sold in kits in one package (2x, 4x, 6x, 8x) may cause problems. Even if they are of the same model. This is because memory makers may change chip vendors during different manufacturing cycles. Memory sold in kits are made in the same production cycle and are tested at the factory guaranteed to work together.
It's hit or miss mixing up memory of even the same model, let alone different brands even if they have the same specs. You might be better off selling your 32GB modules and buying 64GB. However do note that DDR3 is being phased out and getting harder and harder to find (and more expensive due to decreasing stock levels).
