new computer build, almost finished, - the case LEDs/fans and a few tweaks to go.
lots of software work to learn, and more bios settings to learn, - bios loop if I go over 6000mhz, 4x 16gb ram with xmp can be a bit tricky, also, the 6000mhz is stable and stock cooling. in a few years, prolly buy a few 64gb sticks of ram. (I think you will all find this an interesting build.)(UFO)

Made a similar cooler 25 years ago. Reservoir, German fish tank pump. Two beautiful CPU and GPU copper water blocks. I used water wetter for coolant.

Should of got 2 X 32GB set for a better chance of running a higher speed, no such thing as quad mode on a dual channel board.
Still a nice PC.

@caution1397 , just in case it wasn't clear, the issue is that you're running in what's sometimes called a 2DPC (2 DIMMs per channel) configuration. The memory controller on modern desktop CPUs is only dual-channel, but by populating all four DIMM slots, it's having to drive 2 DIMMs in each channel. This hampers your ability to achieve higher speeds and tighter timings.
You could confirm this by pulling one DIMM out of each channel and then see what speeds and timings you can achieve. Run a memory benchmark, and you'll see that populating all 4 slots isn't helping you, performance-wise. It's something people only do when they need more memory capacity than they can achieve with just 2 DIMMs.
Maybe you know all that, but the term "quad mode" sort of implies otherwise.

Okay, I see the point of confusion. The explanation gets at how DDR5 works, compared to previous DDR standards. All DDR-class DIMMs have had a 64-bit data width (leaving aside the detail of ECC) and, until DDR5, the entire thing acted like a single channel (i.e. you could only read or write 64 consecutive bits in memory). You basically send the DIMM an address and either send or receive data in 64-bit chunks. DDR5 changed that, by splitting each DIMM into two, independent 32-bit channels. This means each channel has its own address and data bus.
What's happening is that you're switching the way the memory controller interfaces with the DIMMs between treating the pair of 32-bit subchannels as one logical channel (yielding a total of 2 logical memory channels, across the entire CPU), and independent 32-bit channels (yielding a total of 4 memory channels, across the entire CPU).
The total amount of data that can be sent or received per DRAM cycle doesn't change, but by unchaining the subchannels of each 64-bit memory channel potentially allows more memory-level parallelism to be exploited. I did a quick search, but haven't found any benchmarks comparing the two modes. I'd expect no more than a single digit % change.
@thestryker , do you have any more info on this?
That's different. It was a true quad-channel CPU/platform, with a true 256-bit data path to memory. Arrow Lake has only a 128-bit memory interface, no matter what motherboard you use it on.
Old article. Refers to DDR4 and 256-bit vs. 128-bit.
Anyway, if you don't believe me, an easy way to confirm is to run a memory benchmark on your machine in dual and quad modes. I'd be interested in seeing what results you get. Furthermore, you could pull two of the DIMMs and it should still allow you to enable "quad mode" and you'll still get comparable results as you got with 4 DIMMs.
BTW, thanks for sharing your screen shots. I didn't know about this detail of Arrow, before now. Rather, I assumed that all DDR5-capable CPUs supported what they're calling "quad mode".

I can't speak to your priorities, but if I were building an Arrow Lake PC, I'd be trying to use CUDIMMs. Those use a superior technology, which is called a CKD chip. Basically, it provides a cleaner clock signal for the DRAM chips to use, which enables better stability at high speeds.
TechPowerUp has this explainer, as well as a "performance showcase" using DDR5-9600 modules:

Unlock the potential of cutting-edge DDR5 memory technology with Clocked Unbuffered DIMM (CUDIMM)! Follow along as we explore how this innovative solution is redefining performance for gamers and professionals alike.
They were also able to achieve DDR5-6400 speeds with a quad-DIMM setup, using CUDIMMs:

i ran a quick test.

The only person I caught talking about it was Roman (der8auer) and he made it sound like this was standard function for the ARL memory controller. This article mentions the memory controller design difference, but just in passing: https://skatterbencher.com/2024/10/24/arrow-lake-memss-overclocking/
As far as I'm aware there aren't different modes for the ARL memory controller with regards to independent channel level access. I believe Asus allows channel level power tweaking which might matter for XOC.
edit: for the on topic my sig system since I hadn't posted it at all 🤣

The cooler and case fan are barely audible. I have had loud coolers before. This one is pleasant.

same, omg the new comp is so silent, interesting mention, this intel arc GPU is weird, the fans are always "off", the only time they come on is when the vid card goes over a certain temp, I think it's 50oC, - my old comp was so loud. lol

I also have an AM4 x570/5950x with a EVGA RTX3080 ti OC FWxxx. I am not much of a gamer. The three cooling fans stay off 90% of the time. Overkill!
