I set RAM frequency to advertised spec instead of using XMP(question)

    I feel like I just got a bunch of reddit tier responses except for this this one:


    The thing is, it and the combination of different size modules worked perfectly fine with my 3700x and x570 setup. The RAM is tailored made for it. It even worked perfectly fine when I had the 5800x3d in the old x570 motherboard. The bios was up-to-date.

    While I was having fun playing around with Linux last year I was getting freezes and lock ups and my computer crashed a few times. I disabled XMP and it continued to do it. I figured out it was the motherboard and replaced it. I didn't enable XMP until about a month ago.

    With the frequency manually set to 3600MHz it passes testmem5 without issue.

    Without XMP, yes it's supposed to just work no matter if you have matching modules or not..Everything I wrote in my replies is about getting XMP speeds.

    I mean, I told you guy's it working just fine with the RAM frequency clock manually set. :D

    I just came here wanting to know if the motherboard bios is doing it's own calculations on everything else when it's set to auto. :D

    "auto" is known to also be "default"

    with xmp disabled and selecting the higher speeds ,indeed the motherboard will select its own timings ect, however they are usually jedec derived timings, which are really bad, the jedec for 3200 is cl21-cl24 depending on the kit, jedec timings at 3600 ar probably cl 24-26 with a realllly loose trc. just about any stick of memory will operate at those timings.

    i think most of the focus of the dicussion was on xmp , because running without it is not something many people would do, for good reason.

    i mean dont you want to get what you paid for? .

    If your mobo has the latest bios then OK.
    But if you mobo is some what lacking on combability and there is a newer bios then upgrade to that.
    The you can try your settings again.
    Come to think of it. I upgraded my bios just a few weeks ago.
    Heck, I may as well check out if can tweak it a little more. :eek:
    I doubt it. :(
    I just love wasting time in the bios.:rolleyes:

    EDIT: No way i'm in from 3200xmp to 3600?
    Right time to see if I can tighten up my timing and of course run some ram error tests. :confused::cool:

    @KissSh0t is right.

    The 8GB and 16GB sticks have different supported module timings in Hwinfo and other differences. Computer crashed on me after a Windows update. I looked at event viewer and it was the same crap. Since it's been 2 weeks since the previous crash I still certain it's the RAM OC.

    I tried setting the frequency to 2399MHz which is the max supported for 5800X3D with 1x4R DIMM's and is a JEDEC frequency on the motherboard. I thought I share that. I think it's cool...

    I took the two 8GB RAM sticks out.

    After some Googling and a few YouTube video's I think there's really no point in going over 3200MHz.

    I set the DRAM frequency to 3200MHz which is apparently the max supported for the 5800X3D with 2X1R DIMM's.

    This is just the stock speed. XMP here runs my modules (2x16GB 2R) at 3600MHz on a 3700X CPU just fine. It has some benefits since FCLK and MCLK run at 1:1 ratio (both 1800MHz.) It's a sweet spot, and in fact trying to go higher than that actually hurts performance due to FCLK/MCLK not running 1:1 anymore.

    But perhaps owners of a 5800x3D can chime in on whether FCLK/MCLK ratio matters much on that CPU.

    For whatever reason testmem5 doesn't work anymore. I'll run memtest86+ tomorrow.

    Good thing I decided to start this tonight. I wanted to play New World tonight but all of a sudden I rather watch TV and read random stuff off my phone all night. Also I need to help someone with something tomorrow and get something else done.

    It's going to be y-cruncher all day Sunday.

    So far so good.

    I say 10 passes should do it.

    just for info
    ASRock X570
    2 x 32gb Patriot 3600 C18
    Both with the above and the Corsair 3200 set i previously had the Mobo just didnt like XMP.
    So i set manually and ended up running the 3600 at 3200mhz but with tighter timings, this gave me the best stability and speed combo.
    Not saying this is the OPs issue but XMP doesnt always work best, even when the hardware suggests it should.

    Last time I checked Teamgroup memory, very often their default XMP timings are CL18, but also list CL14 in the spec sheet of some of their modules if you raise voltage from 1.35 to 1.45. (To get 3600 CL14 for example.)

    Ive spent some time playing with the RAM, to get 1T for example but its a long drawn out process, my Mobo doesnt help as the Asrock taichi 570 isnt exactly accurate with the voltages it states.
    Maybe tomorrow il bump some voltages and see how i get on.

    10 passes and no errors. :D

    All I might do now is run Y-cruncher.
