Pro AV and IT Equipment Corsair Platinum 32GB (4x8GB) 3200 MHz DDR4-3200 PC4-25600 RAM CMD32GX4M4B3200C16

This ram is quality, iv used Corsair on my last 2 pc builds, and have been very stable. For the x99 chipset when thinking of overclocking, getting 3200mhz is a overkill. For stability reasons your liky to have your ram at 2300 or slightly higher. If your not overclocking, then you can use the full 3200mhz
