    Hello everyone!!

    I'm overclocking my RAMs to their maximum 24/7 stable. I'm using 4x16GB Ballistix Sport LT 2666 MHz CL16

    For some reason the maximum overclock that I can get is 3200 MHz CL18 (12 x 133 @1.3V), pretty stable so far, but I can't boot at anything higher than 3200 MHz, is that a Clevo P870TM1 limitation or my RAM can't go any higher?

    This dude over here is able to get 4000 MHz CL20 on a 4x8GB config on an ITX MB. What am I missing?:

    PS: RAM overcloking is by far the most complicated and tedious hardware overclocking

    Each laptop has a limit based on CPU imc and system board trace quality because of design constraints.

    There’s also the fact your memory maybe hitting a wall considering you’re using 2666 and have pushed it to 3200 with loose timings already.

    Only real, valid way to see what is giving up the ghost is to purchase some quality better tier sticks snd work your way up with stock timings. (IE 3800 CL18 sticks running at 2666 snd keep pushing up till the system can’t handle it, drop back down snd then tighten up your timings).

    I just want to add that Skylake-X is designed for Quadchannel use.

    And this motherboard is specially designed to hit DDR 4000 speeds. At least that's what is stated on the Asrock product page.

    This moterboard max support 3200Mhz I Have Crucial Ballistix DDR4 SODIMM 32GB 3200MHz CL16 (BL32G32C16S4B). I try to set 3400/3600 at timmings CL18/19 never run this laptop.

    @jc_denton has his 870TM1 running @ 3333

    @Johnksss has his 870TM1 running at 3467 stable and able to test at 3600

    So that can't be true.

    Unless the sticks are certified at higher speeds, there is no guarantee they will run past their certain speed on platforms.

    There's a reason top tier memory is more expensive once you start moving past 3200.

    So what you mean is that there are more factors to consider when overclocking the memories more than just the RAM specs. I had to loose the timings because it won't be stable at stock timings and at higher clock. Also I had to rise the voltage from 1.20V to 1.30V.

    Maybe I need to drop this question on the P870TM1 sub-forum and see what are people getting when overclocking, because 3800MHz SODIMM memories are a bit expensive to buy and maybe hit the same 3200 MHz wall that I'm facing now.

    Yeah I noticed that the dude from the post is doing quad channel. but I thought the RAM speed was more in to the RAM than in to the motherboard. Do you know if newer laptops are getting higer clocks? I remember the Area 51M R1 was stuck at 2400 MHz which is ridiculous.

    Did you try rising the voltage? I wasn't able to get stable 3200MHz on my modules unless I raised the voltage at 1.30V.

    Interesting. I wonder how jc got that exotic clock speed. 3333MHz is not even possible with 2 x 133 x N or 2 x 100 x N which are the configs allowed on my system BIOS. Also it seems that Johnksss has 3800MHz modules, but he is not able to run those memories at XMP profile, which means that the P870TM1 has some sort of limitation on RAM clocks

    If everyone could OC 2666->3200 modules to greater speeds, they would I think and there would be no market for top tier memory. There's a reason upper tier modules are more expensive. They are rated, guaranteed and give you much more room to play with and rule out your sticks being an issue.

    The trade off for let's say 3800 modules is you can really tighten up the timings (which can be equally as important) at lower clocks frequencies. Corsair kits are pretty beastly but you get what you pay for. I picked up some Ballistix CL16 3200 sticks (2x8GB) and they were dirt cheap brand new (~$70) XMP PnP and working fine in my 870TM1. They flat out will not run above 3200 no matter how much I loosen up the timings or increase voltage while I know my system can do at least ~3466 or higher (tested and verified with a Corsair 3600 kit), but if they could do more, I suspect they would have been sold as such by Crucial.

    Even all desktops aren't guaranteed to run faster sticks due to QVL, poor quality or sometimes the CPU has a poor IMC for high frequencies (but still can easily hit paper specs). Sometimes it's the memory; sometimes it's the host environment; sometimes it's both.

    I had some desktop corsair vengeance 3200 sticks that were CL16 B-die and they crapped out at a bin above even with extremely loose timings. This was on my EVGA FTW Z390 which then took some G.Skill 4000 B-Die sticks and run them like a champ. I tested those same G.Skill 4000 sticks which run like a bat out of hell on my EVGA FTW Z390 in an Asrock Z390 board and they flat out refuse to run at 4000 even with the same 9900k in it at stock. Even pumping up the voltage does nothing. Dropping down to 2666 and climbing, I found the board craps out at 3600, but that's ok because I only needed it to run those same Vengeance 3200 sticks which in the Asrock Z390 board still won't go above 3200.

    After 3200 (or even 3000 some would say), unless you are running known, good, cherry picked 3200+->4000 sticks that are sold as such, nothing is guaranteed.

    I, personally, would be happy that I was able to get 3200 out of the 2666 sticks, albeit CL18 would have me increasing to 1.35+ to tighten up those timings if possible. At that point, you have to ask yourself do you want to drop $200-400 on memory sticks to eeek out 2-3 higher bins and/or (more importantly) much tighter timings? I'm sitting on a brand new set of factory sealed Corsair 3800 DDR SODIMMs https://www.corsair.com/us/en/Categ...3800MHz-CL18-Memory-Kit/p/CMSX32GX4M4X3800C18 asking myself the same question for the last month or so while they sit up for sale lol. Eventually I'm going to cave and I know it or a system is going to come in needed memory and I'll move my Ballistix sticks to it and then crack open the good stuff. :p:D

    Oh, ok. :D I was referencing the 870TM1.

    lol, If I were you I'd be so tempted to open that brand new memories and install them in to my laptop and see how far can I push them. I wonder if there is a laptop that can actually hit 3800MHz in RAM, anything over 3200MHz seems pretty rare. A shame considering new PC MB can push up to 5000+MHz

    I'll try to lower my CAS latency a bit and see if I can manage to get it stable. But overclocking RAMs is so time consuming, a lot of restart, trial and error and a lot of testing to check stability. On a side note, I wasn't able to get 3200MHz CL18 stable with voltage over 1.30V. Is that normal? I mean that config was stable @1.30V but unstable @1.35V+.. that doesn't makes any sense to me, unless that's a board limitation of some kind or a temperature issue, because more voltage equals more stable RAM? isn't it?
