    KENZY9
    thiste got a reaction from KENZY9 in Ryzen 3000 RAM Frequency sweet spot   
    Hello everyone,
     
    So I have been thinking & looking to build a new rig & have a bazillion questions. But I'll start with RAM:
     
    My platform of choice is a Ryzen 3700x with Asus TUF Gaming MB. Here's my understanding of RAM frequencies for this: according to this graph (attached image below), the so-called "sweet spot" for Zen 3 RAM is 3733Mhz at CL17. Many people choose to buy 3600Mhz CL16 because it's a lot more readily available & cheap than 3733CL17. I have been looking at G.Skill 32GB (2x16) 3600CL16 that I should be able to get around 225€.
     
    However I just stumbled upon a pretty cheap Patriot Viper 3733CL17, but it's not on the Zen 3 list of supported RAMs ( pdf here ). Comments on Amazon do say there is zero compatibility issue though. This is a 2x8GB set so I would want to double that to get 32GB ( 2 x 86€ = 172€ total ).
    So my questions are:
     
    - Is this a good opportunity to get a native 3733CL17 for a good price? Is frequency more important than brand? The chip brand isn't disclosed but there are hints that this is a Hynix kit rather than a Samsung. Is Patriot a reputable/reliable RAM brand?
     
    - Should I instead stick with 3600CL16 with a bigger brand like G.Skill & pay 53€ more? 
     
    - Are there performance differences between 2 sticks of 16GB  and 4x8GB? If yes, what are they?
     
    - Might I try to find a 3600CL17 instead, and overclock it to 3733Mhz? I'm no overclocking expert, but it should be doable, wouldn't it?
     
     
    Again, keep in mind the 53€ difference, that not negligible.
     
    Thank you all for the help!
     
    P.S.: the G.Skill 3600CL16 is Samsung 16-16-16-36, the Patriot Viper is claimed at 17-19-19-39, the G.Skill 3600CL17 is Samsung 17-19-19-39.

    thiste got a reaction from Blai5e in PC fails to post after resetting the CMOS, then does with CMOS not reset??   
    OK so this discussion allowed me to reflect on it and I understood what happened & fixed it.
     
    So, the PC didn't post because the CMOS was in fact not cleared, I don't know why it DID post when I put my GPU on the second PCIe slot but whatever, thank god for it.
    I lowered the IF to its default frequency of 1800MHz & it worked perfect after that. I put the GPU back on the first slot & no issue.
     
    Thanks to all for allowing me to reflect on the situation, it kinda cleared my mind.
