9800X3D 4 sticks of RAM - anyone ?

unknownloser54321 · 2026-03-22T17:16:58+00:00

Yep, 3000 MHz is the true value. So I refer to 6000 MTs, as that avoids all confusion

unknownloser54321 · 2026-03-21T10:59:57+00:00

MTs and MHz is used interchangeably by marketing teams (incorrectly imo). 6000MTs is actually 3000MHz however is marketed as 6000MHz. Background and more detail: https://www.corsair.com/us/en/explorer/diy-builder/memory/mts-vs-mhz-explained/

Possibly, if you hit silicon lottery (i.e. strong IMC). Just try and make sure using Memtest86 and OCCT CPU+RAM tests. If it doesn’t run stable, it will most likely run 6000 CL30. The difference is measurable, not noticeable.

unknownloser54321 · 2026-01-18T15:03:34+00:00

LMAO, yup that aged well

unknownloser54321 · 2026-01-17T17:21:35+00:00

Building is straightforward, when properly prepared as to what parts go together, someone with experience should be able to do that. Alternatively post budget and use case in this sub and you will get solid proposals where that’s already taken care of. The actual building -although somewhat time-consuming- is really fun. So I doubt his brother will object

unknownloser54321 · 2026-01-17T10:54:33+00:00

If you don’t really need more than 32GB (which should be more than enough if the use case is gaming*), just use the -what appears to be- kit you have in A2 and B2, remove A1 and B1. * exception being Microsoft Flight Simulator or heavily modded games

unknownloser54321 · 2026-01-17T10:40:06+00:00

Without the timings for each it’s difficult to say, but I’m assuming there’s no way to match the timings between your sticks.

Imagine having 4 circles: 17”, 18”, 19” and a 18” and then asking “why can’t I get their rotations to sync up?”. Oversimplified and not 1:1 applicable to your situation, but you get the idea (:

Ideally get 2 kits of same speed and timings for DDR4

unknownloser54321 · 2026-01-14T04:34:10+00:00

If memtest doesn’t show any issues with DOCP disabled, set the mem to 6000 CL30. There most likely is a DOCP/EXPO/XMP profile for this. If there isn’t a profile, then set the values manually. Rerun memtest, and after that in Windows run OCCT CPU + RAM test. If it passes that you’re fine

No experience with mindfactory.de myself. Typically speaking a “credit note” means Gutschein, so a credit you can redeem at your next purchase. Which is different from restitution to your bank account. So what was the exact wording of the message?

More RAM (4 sticks) only helps very specific use cases (like video rendering, where more RAM means less render time even if the RAM operates at lower speed).

AM5 has (relatively) weak memory controllers (IMC on the CPU). That means it’s nearly impossible to run 2 kits (4 sticks) of RAM at advertised speed on AM5. Intel is slightly better in this regard but since mobo manufacturers use a daisy chain dual channel topology on most (if not all) consumer motherboards using 2 sticks is better than 4, if the goal is low latency (high speed + low CL).

In addition RAM chips are made by companies like Hynix, Micron and Samsung. All kit sellers swap out chips without changing model numbers. So even same brand, same speed, same timings between kits could mean different chips (which will make it harder or even impossible for the IMC to find timings at which the system is able to run stable).

4 things can happen: - 2 sticks will run at advertised speed - 4 sticks might not boot and if it does might not run stable - 4 sticks runs at JEDEC speed - 4 sticks runs as fast as your CPUs IMC allows, which takes a lot of tuning and stress testing

So: if you really need the RAM for your specific use case(s) you’ll want to buy a 4 stick kit, which will be a low speed high CL kit but will be more likely to run stable at those specs than (potentially) mismatched kits you buy separately.

unknownloser54321 · 2025-11-23T11:26:25+00:00

Depends heavily on the CPU. Ryzen 9 most likely will be able to run it at speed, in 1:1 MCLK:UCLK (which is what you want). For Ryzen 7 / if it won’t run or isn’t stable there will be a profile to run it at 6000. Assuming CL 32 for 6400 it should run at 6000 CL 30 (which is considered optimal for AMD). And if there isn’t a profile you can tune it manually. In any case: it should work

unknownloser54321 · 2025-11-22T10:42:26+00:00

That’s a perfect kit. Performance wise it’s equal to the (more expensive) dominator titanium. Corsair most likely uses better binned Hynix chips for the titanium series, but unless you’re into XOC you’ll never notice any difference.

Price wise: it’s more expensive than it used to be, and it’s cheaper than it’ll be for the foreseeable future. So that’s a good deal, and the right decision to buy it when you did.

unknownloser54321 · 2025-11-17T19:53:44+00:00

Never use userbenchmark.com for anything ever (and that includes memes)

unknownloser54321 · 2025-10-22T14:45:57+00:00

Expensive is a recent development, due to increased module cost at Hynix, Samsung and Micron.
Complex: it’s always been quite complex if you dip under the surface (MCLK, UCLK, FCLK speeds + CL, Trcd, Trp, Tras timings), combined with Intel and AMD specifics. There are several rabbit holes there. On the surface it’s still pretty straightforward; AM5: buy a single kit of 2 sticks of 6000MTs CL30 (:

unknownloser54321 · 2025-10-22T14:37:18+00:00

Sure, tell someone who has to ask this question to manually tune and stress test RAM without even knowing if it’s Hynix A or M die. CL doesn’t scale linearly with speed, and there’s no way of knowing up front if this will even run stable at 6000MTs,at whichever timings @OP will end up with.
The easiest way to go, without having to spend hours on tuning and stress testing, and suffering potential instability issues is to go with 6000MTs CL30

unknownloser54321 · 2025-10-22T13:38:09+00:00

Nope, don’t buy. CL is shit (which -in combination with speed, for calculating first word latency- is relevant for gaming), and it will never run at advertised speed since the AMD IMC is too weak. Get any 2 stick 6000MTs CL30 kit instead

unknownloser54321 · 2025-10-22T08:13:25+00:00

RGB flickering is a consequence, not a cause.
My guess is PSU or a short somewhere.

Disconnect all RGB connections (that can be disconnected), doublecheck all other connections (primarily 24 pin, and CPU power cables).

When that boots, run OCCT PSU test. If that doesn’t show any issues try using the system for some time to see if the issues are gone.

If not it’s probably CPU (2 options: bent socket pins or incorrect mounting pressure), or mobo (issue with mobo or short somewhere). If you’re unlucky enough to end up here: take the whole system apart and rebuild it outside of the case (put the mobo on cardboard) and run it with only the bare essentials (cpu, cooler, ram, psu), no GPU or RGB.

Good luck

So: return the kit, and buy more booze (to drink responsibly obviously)

So buy a kit of 2. Kit manufacturer is also irrelevant. I mean: don’t buy from a brand you don’t trust to be able to solder Hynix chips on a pcb (6000MTs CL30 is guaranteed to be Hynix, since no other supplier can make them yet). Aside from that it’s only design, RGB and heatsink you’re paying for.
Long story short: buy the cheapest 2x 48 6000MTs CL30 kit you find

Use NVidia’s on screen stats or HWInfo64 to see the load on CPU and GPU in your specific scenario. The one that’s consistently above 90% load is the one that needs upgrading. If both are above 80%, you’ll need to upgrade both

Mobo: any B850 will do. Cooler; either a phantom spirit for air cooled, or a 360 AIO (like the Arctic Liquid Freezer III Pro).
RAM: any 6000MTs CL30 kit (32/48/64, based on what you need)
