Discussion Raptor Lake Build Thread

[DooKey]

Those that have a Raptor Lake build should chime in with what they have. Post your build and system benchmarks if you have any.

My build:

13700KF
MSI Z690 Force WiFi
32gb G.Skill 7200 CL34 DDR5
2tb Samsung 970 EVO NVMe
Thermaltake ToughPower GF3 1000w ATX 3.0 PSU
Gigabyte RTX 4090 Gaming OC
Noctua NH-U14S HSF

Great system that runs cool, quiet and fast. Upgraded a 12700K to this configuration.

Edit: new BIOS out that allows my MB to run DDR5 at 7200


Benches:
CPU at stock, HSF tower setting in BIOS gives me a 28922 CB23 score. (score updated later in thread)

Purchased Seagate 530 FireCuda instead of the Crucial P5 Plus!

530 is pretty fast but P5 isn't that bad either. I'm using it. What made you change your mind?

The occasional errors I get with my 12700K+Z790+DDR5-4600 28-30-30-60 build are amusing.

Today, the Mystify screensaver froze. Moved the mouse and it got back to Windows. Ran the screensaver again. Some time later (probably 15 minutes), I get a BSOD saying a critical process died. RIP, critical process

So far, no crash yet while doing something important. It's when the system is doing non-CPU-intensive stuff that I have seen anomalies or crashes.Any idea what setting can be changed in BIOS to prevent these?

I had freezing problems with my 12600K, Z690 and DDR4 build, I liquidated it completely, I have no part left of it except an SSD and power supply.

There may be some unavoidable problems in compatibility of many hardware and software parts of a computer, it is after all one of the most complex things mankind has ever developed.

My new 13600K, Z790 DDR5 system is too young (20 days) to access occasional errors, so far nothing happened, except one crash which I believe was caused by ARC A770 graphic card.

I think the system overall is fine. No hardware issues. It's just that I'm doing the unwise thing of using an EXPO kit with an Intel mobo. And the ASROCK mobo even identifies it as an EXPO kit and allows the option to set EXPO profile but fails. It then denies me any way of setting the 4 JEDEC profiles it shows in the memory module information screen. So had to manually tune it to the lowest timings and speed that it would boot without issue and run Windows. I wonder if there is any setting I could use to stabilize the RAM kit.

I am using Kingston EXPO kit as well. It runs fine. It has both EXPO and XMP profiles in it. P/N: KF560C36BBEK2-32

Mine doesn't have XMP profiles.

 

[Kocicak]

Mine doesn't have XMP profiles.

Throw it away.

Have you tried to manually tweak it to tightest timings or highest speed? If so, what did you manage?

No, I am a simple guy, I just select a profile, that is all I can do.

I was looking at the 13500 combined with the Asus H770 Plus D4 to replace my old B350 & 1700X server
3 x M.2 PCIe4.0x4 (1 from CPU, 2 from chipset)
1 x PCIe x16 slot at 5.0x16 (from CPU)
2 x PCIe x16 slots at 4.0x4 (from chipset)
For a board with plenty of expansion + CPU cost of only $410 with cheap DDR4? Basically twice as fast CPU and I can reuse my old memory (and at its rated speed now).
Am I missing some limitation of H770 chipset?

I cannot find a single B650 board that comes close in price for features. And while more of the features are from the chipset it has 2x the bandwidth connecting the chipset to the CPU to make up for that.

 

[igor_kavinski]

Am I missing some limitation of H770 chipset?

Not that I can see.

RAM QVL:



Wow. Don't think I've seen anyone do more than DDR-4000 on Alder Lake and ASUS has tested 5066 MHz successfully

It's gear 2 mode, slower than DDR4 4000 gear 1. Think about it as DDR5 5133, but without DDR5 perks.

Are you using a negative offset voltage to undervolt? I find that these kind of reboots are related to idle or low CPU usage voltage being too low.

In my new 13900K system, I had one idle reboot when I was using the a global negative voltage offset. I switched to using the V/F curve to only reduce the voltage of the non-idle clocks and so far no repeat.

 

[igor_kavinski]

Are you using a negative offset voltage to undervolt?

Nope. No undervolting.

 

[igor_kavinski]

Tried the power saving power profile just now with 12700K. It downclocked to as low as 470 MHz. Don't think I've seen a CPU go this low before.

 

[coercitiv]

Am I missing some limitation of H770 chipset?

I don't think so, it's the B760 that introduces the further downgrade to just 4x DMI links. With that H770 board you should be fine in terms of chipset connectivity, and I assume you're not aiming for more than 100-125W TDP for the CPU, which means the undersized VRM cooling won't matter either.

I have! My k6-233 went as low as 233 MHz! And my P5-100 went all the way down to 100 MHz! And my 386dx40 . . . wait, nevermind.

 

[igor_kavinski]

wait, nevermind.

Lowest you have seen a modern CPU go? Mine was 800 MHz before I saw the new low.

 

[DrMrLordX]

I got both my 1800x and 3900x down to about 800 mhz static.

 

[coercitiv]

Must downclock harder:


This was using Balanced profile btw. Deep C-states and Speed Shift are manually enabled through UEFI, tough Auto usually enables them anyway. In the Windows power profile "Minimum processor state" was set to 0%, though usually I keep it at 75% or even 100%, since Speed Shift partially overrides this setting anyway and the bulk of energy savings comes from sleep states, not lower clocks. Keeping higher clocks should also reduce latency.

Question - Post your MaxxMem² score

Thanks to Det0x for using this utility in his benchmarking and thanks to AdamK47 for posting his score, thus making me aware of this utility. Det0x's score: https://forums.anandtech.com/threads/zen-4-builders-thread.2605910/post-40890534 AdamK47's score...

Guys, can anyone post their Raptor Lake DDR5-7600 or higher MaxxMem² score in the above thread? Thanks!
