I think people got the wrong impression with the arrow lake. Because it looks to me like it was just a more efficient 12th or 13th gen chip than something that was supposed to be the next step up.
We’ve known that for a while. Royal Core was supposed to be the next real one, but it got screwed up by various bits of internal politics and Kessler left
Its a completely different core architecture. And not only due to tiles/chiplets.
Well it was supposed to be a redesign and that was expected. However in the discussion 7 years ago Intel getting feedback from hardware engineers and OS devs we told them they were putting too many extra things inside which a lot of us in OS development: Linux and Windows had to patch a lot of timing and processing scheduling on the OS level because those chips are just built wrong. Same with AMD but they fair better at the end just because when they crank the speed inside to compensate for their additions to their chip, it didn't fall apart like the Intel chips. But that is because intel uses parallel bus technology and AMD uses a type of serial mux which the later is better at overclocking internally. Its the reason why overclocking these chips are harder because they are already overclocked.
My Steel Legend got the update on Wednesday. I hadn't noticed. Thanks for the heads up.
Well they need to make a better chip to support ram >5200 without having to sit there and configure it for faster ram. Or what I should say, overclock the chip set so it can support the faster ram they advertise.
Max stock DDR5 speed for Arrowlake is 6400
Intel is a little different story than AMD. Since they divided the memory controller between the processor and chip set, they had to crank the ram speed up to compensate for the delay they caused in the circuit by doing this. If Intel didn't try to copy AMD who fully put the controller on chip, Intel processors would be 30-50% cooler.Max stock DDR5 speed for Arrowlake is 6400
All CUDIMMs should be set for this, to default to 6400. Since they released with Arrowlake or after Arrowlake release.
Hopefully newly released UDIMM sets will include 6400 JDEC profiles. Because CUDIMMs are a ridiculous upcharge, right now.
If you want some help, Download and run CPU-Z and screen shot the memory and SPD tab and lets see if some alternative timings will fair better.
AMD doesn't put the memory controller on the CPU chiplets, they're on the I/O die. At least on the Ryzen desktop CPUs. A lot of the APUs are monolithic, but not all. For example, Strix Halo is 2 CPU chiplets plus an I/O die with a big fat iGPU in it and a 256-bit memory bus connected to the I/O+graphics die. EPYC and Threadripper are the same as the desktop chips. Intel Xeons are different. They're multiple tiles, but each tile has CPU cores and a memory controller. Like we have some Sapphire Rapids machines at work with 4 tiles and each tile has a 128-bit DDR5 controller. So "dual channel" but actually quad since DDR5 is 2 32-bit channels per 64-bit DIMM. Putting the memory controller on a different die can work quite nicely, Intel just didn't get it quite right on their first real try.
I will keep that in mind in a week or so. As the timings I used for big improvements on my 7200 set with a 13600K-----barely improve latency on my 265K.
The issue seems like with the 265K, its internally overclocked, and need to approach the timing of the ram accordingly instead of setting a timing they want. Ideally you want to time the chip so the ram has a crazy fast latency like 1-1-1-1 or 2-2-2-2 but with the multiplier cranked inside the chip, I don't think its possible.
BIOS with 0x114 or newer microcode. The Windows bits should be taken care of by Windows Update. If you're not running an up to date Win11 24H2 set the power profile to "performance" in Windows. Maybe do that anyway. Intel says they fixed it (or rather had MS push out a patch to fix it), but the patch changed the default "balanced" to be the same as "performance", so no point in not setting it to performance.
Increasing Ring multiplier and D2D (Die to Die) multiplier.
if there is bios updates do them. Memory timing is more important than a powerful processor. Windows will go through some more Kernel patches as well as Linux before its over. Even though for them they are about to incorporate a rust based subsystem to replace gnu tools.
Finally shipped.
I always though it was speed or how much it could be overclocked while AMD focused on efficiency.
This RAM arrived today and I installed it.
I got this RAM after reading about how well it worked for you. Thanks!
cool!
