    DDR5 4800 is the JEDEC spec. It will run over that with a manual setup. Probably twice that speed~

    What for though? The RAM timings will have to increase and probably the gear setting too.

    You'd need to buy higher speed DDR5, I think, assuming the RAM timings aren't much different.

    There’s no gear on cml. Dual rank tops out around 4600 for daily with tight timing. Single rank around 4800. That’s bdie. Rev are and djr can do daily 5000 but timings are looser and bdie beats them in real workloads.

    What good tuned bdie looks like on cml: [​IMG] [​IMG][​IMG][​IMG]

    If 4800mhz ram can only run in gear 2 then it will absolutely make sense to OC the ram since 8000mhz has also been shown to run in gear 2 and if 4800 can run in gear one then 9600mhz should be doable in gear 2.

    Diminishing returns I think. Quad channel motherboards would be the way to go if people want to spend this kind of money.

    There’s nothing exciting about cl40/4800 but I guess you gotta start somewhere.

    I'm no expert, but in a world of CL14/3200 or CL16/3600, that would be a fair bit slower, aye? For lots of quick random accesses anyhow.

    Early days as you say.

    Quad channel needs CPU and IMC support though. AL-S already has 1,700 contact, so to have twice as many memory channels would require even more. Won't help power either and power is already high. I'm sure Intel will make HEDT and Xeon versions with more memory channels.

    12900K will be my first major CPU upgrade since around 2015 and the first time ever I have bought a flagship CPU. Always bought a step down from the top or good mid-range with scope to OC and get top range performance. That was of course back in the 7th gen days (6700K). Things have changed....

    No intention of buying a DDR5 board but whatever Gigabyte have with skt1700 is what I'll get in the £150 range and then just reuse my DDR4 3600MHz. I don't need to eek out every ounce of performance to pad a benchmark result, I just want a significant upgrade from my 6700K which is now showing its age in workload tasks like exporting a few hundred photos or rendering a video! I've been editing! I'd also like to game a bit more care-free without the CPU being the bottleneck!

    I cannot wait as this will secure me for the next 5 years at least I think!

    You might want to wait until the actual reviews are out before you blow your load on something that might not be great for what you do. :)

    What would be the other option if that turns out to be the case? I'll be sticking to Intel either way really as am more familiar with them and don't want the faff of potential RAM/configuration issues and other stuff.

    I use Lightroom, Photoshop, Davinci Resolve and other workload apps that are heavy on multi-core performance. With the odd game here and there of course but mostly workload usage.

    That almost like saying you'll be sticking with Canon regardless of how good Sony are, just saying, as an example. :)

    But I will be sticking to Canon :p :D (not a fan of Sony ergonomics)

    I kept the Canon and bought Fuji to go with it. :p

    If you are sticking with Intel then you have no other option. Depending on how heavy your workload is though i might look at 24 core threadripper. Had zero issues with memory and configuration on my 5950X

    TBH I would not mind going back to AMD if the reliability/stability etc all checked out. I just checked out current Threadripper prices and closed the tab with watery eyes so that's out the question. I want to spend less than £1k which includes the CPU and mobo and a new AIO as my H115i is getting on a bit. 5950X looks good though but I still would prefer something new to make the whole thing feel like I've stepped into 2021/2022 properly, also that brand new model feel :p

    I think Threadripper for my needs would be absolutely overkill anyway though. I just want more core power which it seems any of the recent chips even 10900k would trounce my 6700K in multi threaded performance which Lightroom would love.

    Hell if 12900K doesn't stack up as a sizeable improvement over a 10900K then I'll chuck in the towel and just get a 10900K and call it a day for a few years I guess and then just get the best speed RAM I can get as I will be looking at 64GB soon as at times 32GB is nearly fully utilised.

    Looks like memory controller gears are going to be a problem on Alder Lake. I hope they add 'gear 1' support for high speed DDR4 too. I can't help thinking Intel is trying to obscure that the memory controller will be running slower when using DDR5 RAM.

    Most people planning a build should probably wait until January 2022, for the B660 motherboards in my opinion, as the Z690 boards will probably be £150 or more on launch.

    If Intel wants a power efficient Alder Lake CPU, they should create an 8 core version with the small cores disabled ;)

    It will be interesting to see if the 12400K can clock to ~5ghz.

    I'll be keeping my eye on Raptor Lake news in 2022. It will be interesting to see if they end up supporting DDR4 for the 13th gen.
