    I haven't explored ram settings yet. Never really played with them before.
    I normally just buy ram with good timings, set the XMP profile and let it be.
    Mine are samsung B die 3600 with Timings of 16-16-16-36 @ 1.35V.
    I see Gskill has now released a similar set with Timings 14-14-14-34 @ 1.45V
    Looks like the same sticks as mine with tighter timings and a little higher voltage.
    Very tempting to give those settings a try. What is the worst that can happen if it doesn't work?
    Just don't want to corrupt the bios or fry the memory controller on the cpu.

    I found this to be a very interesting post by a helpful member on the MSI forums.
    It is written with a somewhat "MSI board and Rocket Lake CPU" point of view.
    But a lot of it applies to all current memory/motherboards/cpus.

    Hopefully you guys will find it interesting as well.

    IPC had really good gains this is just from tuning memory and extending duration of boost times without overclocking the CPU itself Overclocking the Z590 Motherboards-ipc1850k.png

    That looks promising for your Comet Lake setup. I wish it was as simple as increasing Dram Frequency for me.
    But with Rocket Lakes new memory controller, anything above DDR4-3600 kicks in Gear2 mode settings.
    This introduces a divider for the IMC, making it run at half frequency. A loss until about DDR4-4400 or so.
    Getting this ram to run DDR4-4400 seems highly unlikely to be able to do at decent timings and voltage.
    All I have read points to my only option of finding the tightest timings I can run DDR4-3600 with safe volts.

    Much to read and research for me today. Never to old to learn a few new tricks.

    Hi,
    On 3600c16 if 16-16-16-36 there really is very small gains for anything over 4000 mhz with decent dimm voltage 1.45v

    So I just tune it and call it a day anything higher is just not worth the time for the meager gains.

    I am already seeing this on my current setup.

    An all core overclock to my 11600k's 4900mhz max turbo frequency is easy to hit with reasonable voltage.
    With a good custom water cooling loop 5ghz stable is only possible by adding a ridiculous amount of voltage.
    Anything beyond that is simply impossible to stabilize, even with adding scary high amounts of voltage.
    (1.5 and beyond. Admittedly unsafe voltages, but in my disappointment with it I was not afraid to kill it. )

    So either I just have a real dud of a cpu, or its literally already running at the very peak of its potential.

    This is great news for the average user as they are guaranteed to get max performance out of the box.

    Not much fun for an enthusiast who assumes that with top notch cooling you can squeeze a bit more out of it.

    My 3770k ran a 1000mhz overclock(3.5-4.5) for almost 10 years. And continues to run at stock in the wifes pc.
    This one can barely achieve a 100mhz overclock. The upside is even at stock settings it does run very well.
    Just no room to play. Not complaining, just observing. For a budget build it handles all my needs with ease.

    1x600k do not overclock well unless you are real lucky. You have to get up into the 1x700k or 1x900k price range to get a good chance. I have a bottom of the barrel 10 core 10900kf I can clock to 51x all core at 1.305 vcore at load. I just have an AIO and it cools fine - no custom loop needed. I can also get up to 53x with fewer active cores ,but it is not worth the 1.4+v and current required to get some modest gains.

    Intel does bin their k processors. In order of overclocking ability it is something like 10900k > 10700k > 10850k -> 10600k, etc. But it is a lottery. The specs for their processors are based on silicon wafer quality yield and the level of lithography (14 nm vs. 7nm etc) . They have to limit the speed of their mainstream processors to a least common denominator, based on their yield and lithography, that will guarantee fault free operation for their warranty period. This means there will be lots of processors that perform better than the the least common denominator specs. These are then binned and you draw a lottery card on whether you will get a good overclocker or not. Or something like that. I can't see this changing as long as there are enthusiasts - they can make more bucks that way. But the price to play that game is getting more and more expensive - motherboards, memory and chip prices are skyrocketing. That could kill it.

    But yeah, the gains are slim but tinkerers will tinker

    Those chips with stock tight timings sell out fast, I settled for 16-18-18-36 but apparently the Asus AI OC evens it out.

    Still going keep looking for some with lower numbers.

    See if they will run at their rated timings, 16-18-18, they should.
    These are good, G.SKILL TridentZ RGB Series 32GB (2 x 16GB) 288-Pin DDR4 SDRAM DDR4 3600 (PC4 28800) Desktop Memory Model F4-3600C16D-32GTZR - Newegg.com

    That is a good set of RAM, in addition to trying the timings, it appears you @Hemimax are running at 2666, try setting freq at 1600 which equal 3200. That will match the specs shown for you. DRAM V should be 1.35

    That's what I meant to say. They should run a 3600 16-16-16 3200 16-18-18 easily.

    I was reffering to his corsair RAM, but yes they may do 3600 too

    Thanks guys, is this better

    I should have said I couldn't find any low profile ram with equal timings.
