Windows 10: RAM questions Solved

    RAM questions


    I have 16GB of DDR3 with latency of 7-8-9-9

    I have 8GB at 8-9-10-11

    Will the slower 8GB added in with the 16GB be noticeably slower in day to day tasks? I really don't need the extra 8 and was wondering since I believe the slower RAM will make the other RAM run at the same slower speed.

    I was going to make my RAM drive larger if adding the 8GB won't be something I would notice being slower.

    I figured some of you with the blazing fast newer systems would be able to answer this easily.

    The timing is different, so it's going to be hit and miss if the added 8 gb RAM modules will work or not.
    They should work, however they will run at the slower speed.
    I installed 2x8 DDR4 Corsair Vengeance, along with 2x4 DDR4 HyperX Fury.
    Both have different timings and the Corsair modules were at 3000 MHz.
    I installed the 2x4 HyperX Fury and now the all the RAM runs at 2133 MHz, and with different timings.
    I haven't noticed any measurable difference in my systems speed/performance.

    That is what I kind of figured. The main bottleneck is the hard drive and I have an SSD. I just wondered if things like loading into games, opening larger programs etc, I would notice a hit. I guess I could just stick it in so to say and see how it goes. I just hate going inside a case when nothing is wrong lol.

    All the RAM will run at the slowest, which is whatever RAM is slower.
    Also, it depends on the motherboard. Some motherboards don't play nice with mixed matched RAM modules.
    Stick it in, if it works... you really won't notice any difference. Unless your doing bench-marking.

    They are so old I have no idea the speeds of them. I do know the 8GB is much "cheaper" than the 16GB. I could have bought like 32GB or more of the 8GB at the time for what I paid for the 16GB. I got the latency from CPU-Z.

    Install the modules and than run CrystalDiskInfo.
    I meant to say run CPU-Z, not CrystalDiskInfo.

    You can type: wmic memorychip get speed

    Into command prompt as admin to get the memory speed.

    Seemed to take a little longer once I logged in to get to my desktop than before. It wasn't bad and could have been the CU from earlier today. I have not rebooted since. I have CPU-Z open.

    EDIT: I should have taken screen shots w/o the 8GB in on both RAM pages. grrrrr. didn't think about it.

    Do you still have Dual Channel?

    Yes still dual channel. wmic command returns 1066 on all 4 lines.

    Is the 1066 I see in the command window the actual speed or the speed they are running at?
