If CL30 6000MHz is the sweet spot for 32gb(2x16) of RAM on AM5 boards. What is it for 64gb(2x32)?

Thanks for input. My brother bought some it the Corsair stuff and it's running fine with a 7800X3D/B650E-F combo so I'm now leaning towards that, but will keep an eye out for good deals on the Trident.

I've got 32gb. Regularly see around 30gb in use with just a few browser tabs open when gaming, so I was thinking about swapping to (2x32) 64gb. Not sure it's quite an expense though as I think the Gskill Trident Neo 6000 cas30 are about £225

I've had crashes in MSFS 2024 with 32GB RAM, but that game is a heap of junk at the moment. £225 for the 64GB kit of what we both have already seems madness to me. I'm sure we could get some money back for our 32GB kits but still.

Plenty of 64GB CL30 kits at £180 if you've not fussy about RGB. I got a Kingston set for £145 ish using a promotional code just before Xmas.

I'm not sure Gskill are remotely worth the premium charged.

That is a very good deal. I recall Buildzoid saying secondary timings are more important with AM5, so CL30 may be quoted on the box, but what comes after that number is more important. Granted, the performance difference will be minimal. My ram is rock solid so i am not touching it. If MSFS 2024 crashes occassionally because it isn't optimised well, then so be it.

Try running your RAM at 5800 MT/s or 5600 MT/s and see if that stops MSFS 2024 from crashing.

I should have been clearer. MSFS 2024 crashes as it runs out of ram. I don't even run it at max settings, it is just a very messy and buggy game at the moment.

Ah right, yeah, that makes sense. maxing the RAM like that doesn’t help.

Yea, not good. HWINFO64 ram usage goes red

Thing is, I have no idea how to lower ram usage. Only the very max recommended specs suggest 64gb. Anyway, im not touching it for a while longer as it is so buggy. That’s the only game Ive played where having 64gb would benefit me.

I don't know really. Could be graphical settings (High quality graphics are larger and have to be loaded into the VRAM via RAM so that might be one aspect).

Have you enabled the BIOS feature (the name escapes me) where assets are loaded straight to VRAM instead of going via RAM? Might help.

Rebar? That’s a good shout. I had to disable it 6 months ago to stop Playstation games (HZD, TLoU, etc) crashing.

JollyJamma · 14 Feb 2025 at 10:22

Yeah, Rebar! Update your BIOS and try it again, some games actually now see an improvement in performance with Rebar enabled.

It was buggy at launch that’s for sure.

Thanks for the suggestion. I’ve had a lot of improvements in with the latest BIOS for things like boots times, so I will try enabling rebar again. Glad someone is on the ball around here

The NVIDIA driver should only utilise resizable BAR when there is a performance benefit. You can also use NVIDIA profile editor to forcefully disable reBAR per game if you think it's causing stability issues.

I'm not aware of specific issues with reBAR and PlayStation ports, but can't say that I've looked into it. Definitely try to keep reBAR on as it's a free performance uplift!

Yes, I looked into that. Even when rebar was disabled for Playstation games it still caused crashes that stopped as soon as I disabled it in BIOS (disabling it in Windows/NCP did not stop the crashes. Very odd. Maybe it was something else, that just so happened to stop when I disabled the rebar setting, who knows. I will try it again now i'm on the latest BIOS.

Thanks.

Let us know how it goes!

Just came to me: were you running any OC at the time? That can cause all sorts of weird oddities if it's got a hint of instability.

Will do, all good so far. MSFS does get very close to 32GB (was playing it earlier with rebar on), so let's see if it still crashes. And no, no OC on the core or memory.

So what secondary timings are best to look for please?

As for the Corsair, yes they are about 40% cheaper but there were loads of reports of problems and compatibility issues with AMD boards and EXPO, which was the reason influencing my decision to buy Gskill. At the end of the day you get what you pay for and the Corsair are cheap for a reason.

"Some common problems reported with Corsair DDR5-6000 CL30 RAM include: instability issues, particularly when using the AMD EXPO profile, potential compatibility problems with certain motherboards, occasional freezes or crashes in games, and difficulty achieving stable operation at the rated 6000MHz speed; users might need to manually tweak timings or lower the frequency to ensure stability on some systems"- Google AI

oh no this is what i am currently troubleshooting my way through....hope i am not on a loosing wicket but if its a simple as replaceing ram then happyish days ....

Absolutely Clueless · 18 Feb 2025 at 22:53

I was surprised when i first saw the 'cheap' Corsair 6000MHz RAM. Thankfully it wasn't on sale when I bought my G.Skill kit. Hope you get any issues resolved! Not very helpful i know, but the G.Skill 6000C30 kit is rock solid.
