    asus rampage vi extreme ram problem

    Hello all. I'm having an issue with my computer. when I put 4 sticks of ram in for quad channel, the computer will randomly hard lock in stress tests, in games, and sometimes even when doing nothing. It runs fine with any combo of ram sticks ( to rule out a bad stick) with 3 in, but as soon as I put 4- i get hard lock ups. Is this a bad board, or bad ram? what does it sound like is the issue? Thank yoU!


    Update- i just tested all 4 sticks running in all the 4 left slots for quad channel, instead of 2 left and 2 right for quad channel. its running fine now, quad channel- even for stress testing. So it seems maybe the ram is fine. In this case, does it sound like its a CPU issue or a motherboard issue? it seems like any time i put more than 1 stick on the right side in any slot, i have crash issues. I cant get it to run quad channel using 2 left and 2 right. Yes I checked the manual to make sure I get them in the correct slots for 4 way quad.

    thank you for any help !

    Are the 4 sticks from a matched kit? If not this could be your problem or perhaps a bad connection from the CPU to the RAM sockets.
    Are you trying to run OC?
    Which MB?
    Which RAM?

    asus rampage vi extreme motherboard, newest bios.

    ram is gskill trident z RGB 3200- its 8gb x 4 matching set from a kit.

    problem happens with or without overclock. Runs perfectly fine if they are all on the left slot quad channel, running in quad verified by CPUZ. But any time I try to run 2 left 2 right, ( correct quad channel slots verified by manual) crashes happen, constantly and quickly.

    Hi dandan have you set dram voltage 1.35v ( sometimes needs higher) also vccio try 1.2100v and vccsa 1.175v, it may help? But weird they run on one side only. GSkill run at higher volts.

    Hi,
    Post to the exact set of memory you have
    Sounds like a dual channel set to me meaning only z-series boards on qvl list.

    It happens to a lot of people including me. Putting 4 memory sticks into the slots on the right side causes crashes on stress tests and freezes on normal usage. Putting memory on the left side - stress tests passes perfectly. I've heard this story so many times with this mainboard that I'm 100% sure that this is a ASUS problem - not the CPU or memory. If you find any solution, please share on this forum. I have a big problem as I have 8 memory sticks and I can use only 4 of them.

    Hi rython, I’m using all 8 slots ( 8x8gb ddr4 3600hzs *GSkill rgb ) quad channel,they are running at 3800hzs 15-15-15-34 stable.
    I have noticed in bios channels a,b voltages slightly differ from channels c,d ie; left slots run at a higher voltage (right=1.35 left=1.36)?
    Latest bios caused an upset for them and I had to reseat them but now they are fine at 1.37v or 1.38v, vccsa at 1.10v and vccio at 1.150v,I also set in dram timing to train (enable).
    I think it is a board issue between the two sides that needs tweaking? Causing instability.

    I did not find a solution. I just RMAed my board yesterday. I have heard horror stories of RMA, im worried to get an even worse board back. Mine went in flawless.
