You don't. The zx1 chipset only supports 256GB max. If you need more ram, you have to use the sx1000 chipset. FWIW, the largest memory configurations you can buy for machines with the zx1 chipset are 128GB in an rx4640 (32 slots * 4GB DIMMs) and 96GB in an rx5670 (48 slots * 2GB DIMMs). 4GB DIMMs were never certified in an rx5670, so you can't put together a 192GB machine. -- "Next the statesmen will invent cheap lies, putting the blame upon the nation that is attacked, and every man will be glad of those conscience-soothing falsities, and will diligently study them, and refuse to examine any refutations of them; and thus he will by and by convince himself that the war is just, and will thank God for the better sleep he enjoys after this process of grotesque self-deception." -- Mark Twain
