Question RAM / Power Supply / FAN issue?

[TheDecoy]

Hi everyone,

a while ago a posted the system I bought. I went with the suggestion and changed the RAM to F5-6000J3040G32GX2-TZ5N. It should arrive somewhen this week.

I had a chat with a colleague who wants to buy a similar system and did some research, and he pointed out a few points I am wonder if they are true. Can you please help me out with a fact check.

1. 64 GB RAM might not fit with the Noctua FAN (or raise the need to install it differently?)
2. The 64 GB G.SKILL RAM do not run without error as (the mainboard?) BIOS does not work yet properly with DDR5, corsair dominator would be a more stable pick
   1. I checked the compatability list, the mainboard is listed on the G.SKILL site, but the RAM are not listed on the Mainboard site. Strangley enough the list the exact same version but with XMP instead of EXPO as supported. But EXPO would make more sense with this setup?

3. 850 Watt power supply is at the absolute limit with a RTX 4090 and a 1000 Watt powre supply would be the better and also more future proof pick.

EDIT: Totally forgot to mention I settled with another mainboard. Let me repost the current list of components.

• AMD Ryzen 7 7800X3D Box AM5 (4,2GHz) 100-100000910WOF
• NOCTUA Noctua NH-D15 Computer Kühlkomponente Prozessor Kühler 14 cm
• BE QUIET! Dark Base Pro 901 (schwarz)
• IGABYTE Gigabyte GA-B650E-AORUS MASTER (AM5) (D)
• THERMAL GRIZZLY Thermal Grizzly Kryonaut Wärmeleitpaste - 1 Gramm
• G SKILL DIMM 64 GB DDR5-6000 (2x 32 GB) Dual-Kit (schwarz, F5-6000J3040G32GX2-TZ5N, Trident Z NEO, AMD EXPO)
• BE QUIET! be quiet! Netzteil Straight Power 12 850W 80+ Platinum Mod.

I would really appreicate a quick answer, so I can react accordingly

Someone has an idea? The most urgent questions in a nutshell would be if 1000 Watt would be more clever and if 64 GB (G.Skill) is a bad idea (for gaming).

When using the NH-D14 and NH-D15 series with relatively "tall" RAM, I simply raise the front fan to clear the top of the DIMMs. Your case is more than deep enough to allow this mod.

I suggest installing Windows with XMP/EXPO disabled, to ensure a clean install. Then set it to 6000MT/s and keep your fingers crossed it's 100% stable when you run stress tests. If there any XMP problems, relax the CL (CAS) timing manually by a few clock cycles, e.g. change CL30 to CL32.

Make sure you've got the latest BIOS for up-to-date AGESA mods. High speed RAM stability and the 1.30V limit are highly desirable features.

You're using a 7800X3D, and not an i9 13900, this makes a difference in the recommended PSU. 850w is more than enough for your build.
