Help - 64GB memory upgrade to an AMD Ryzen 1400 system

Tascam · 29 Jul 2025 at 15:24

I posted here about a year and a half ago about upgrading my AMD Ryzen 1400 system to 32GB, which following the advice on here I did with a Team Group Vulcan Z T-Force 32GB (2x16GB) DDR4 PC4-25600C16 3200MHz Dual Channel kit.

So now, I still have the same system (With a better GPU), but would like to upgrade to 64GB. (2x32GB) ? As I use my system for work, I dont really want to take any risks with incompatablity, hence asking on here first. Edit: Mother board is Gigabyte B450M DS3H-CF, Thanks.

Look at the motherboards QVL memory list on the website and buy one of those.

Unfortunately ddr4 memory has shot up in price but selling your old stuff would offset cost.

What motherboard do you have ?

Sorry, thought I mentioned it .... its a Gigabyte B450M DS3H-CF

I'd look at the QVL list for that motherboard and see what it supports. https://www.gigabyte.com/Motherboard/B450M-DS3H-rev-1x/support#support-doc

A quick look suggests that it might struggle to support 64gigs.

Yes, thanks for that - I had a feeling there might be issues as I could find much about it working with 64GB.

Ryzen supports 32GB sticks from the 1st generation. They have worked fine even with 4 (128GB), albeit running at slow speeds.

They were not widely available until afterwards though, so a BIOS update is a good idea, but your board does say in the spec that it supports 128GB.

Your CPU is a summit ridge CPU but there are no 32gb modules in the qvl list so your risking it but most memory.

You could get some memory and try it then return it or get another 2x16gb if team group but you may have to run them at slower speed

CORSAIR VENGEANCE LPX DDR4 RAM 64GB (2x32GB) 3200MHz CL16-20-20-38 1.35V Intel XMP AMD EXPO Computer Memory – Black can be had for £140.

What do you use your computer for that you need 64gigs of RAM?

I think you would be able to run 64gigs of RAM with your current rig but it won’t run at full speeds by the looks of things.

Moving to a newer motherboard (like the B450 Tomahawk) and a new CPU (memory support is much better with the 5000 series) would improve your RAM support but if you’re looking at replacing parts, you might as well consider a new budget AM5 system.

You’ll get better performance with 2 by 32gig modules than 4 by 16gig but DDR4 has lost a lot of value recently as the price has increased and DDR5 has better performance and is quite cheap now.

Why do you think you need 64GB of RAM? 32GB even 16GB is plenty for office work.

Monitor RAM usage and see if you're hitting RAM 100% usage

Video work and now some AI video integration, some of the new open source video models are getting quite large and need to be able to swap to Vram from system memory - the quicker the better. Looks like I might need to upgrade the system.

Zen1 actually supports 128gb per channel, but you’re looking at running DDR4 1866.

1866 MT/s? Ew, gross.

I'd rather upgrade to a new system then.

My basket at OcUK:

1 x AMD Ryzen 5 7600X Six Core 5.30GHz (Socket AM5) Processor - Retail (SKU: CP-3DG-AM) = £169.99
1 x MSI B850 Gaming Plus WIFI6E (AMD AM5) B850 DDR5 ATX Motherboard (SKU: MOT-MSI-05941) = £169.99
1 x Corsair Vengeance RGB EXPO 64GB (2X32GB) DDR5 C40 6000MHz Dual Channel Kit (SKU: MEM-CRS-05108) = £170.00

Total: £517.97 (includes delivery: £7.99)

On really well made boards you can run faster, but not by much especially with over 1 dimm per channel and it’s very hit and miss when it comes to memory sticks. Once you run out of RAM you’re down to page file speeds and 1866 is still massively preferable especially with limited CPU performance. The problem is in many tasks Zen benefits from low latency access so large pools of memory can also bottleneck performance so your average performance over time is affected. It’s very much a balancing exercise to which makes more sense. The cost of 128gb sticks of DRR4 also isn’t exactly cheap and unbuffered sticks of DDR4 above 32gb are extremely rare beasts.

yeah I would stick with something like this

So what are you recommending exactly?

you have 3 choices really,

1) add another 2x16GB ram to your system but run possibly slower ram, depending on speed you run at you can loose upwards of 10%-20% performance. You may even be able to run then at stock stable, who knows.
2) sell your ram and buy 2x32GB, its expensive but if you don't want to upgrade right now to new its the best option.
3) upgrade to new system but ram stability on 4 x ram slots populated is still a lottery albeit its improved considerably, but 2x32GB is more readily available and obviously a 7600x is way faster than a 1400x and faster ddr5 ram speeds.

no way to know what works unless you try, you might have to default to 1866mhz and then manually set ram timings till you find something stable. Another issue you have is sometimes 4 ram sticks from different packages may not like running together, usually you would buy matched pairs, its not something I have run into very often tbh but it does happen and can happen.

If you keep your current system, I would upgrade your cpu, its a old 4 core and slow and you should see massive improvements in performance that could theoretically offset any performance loss from potential slow ram speed in certain tasks. It might also help in ram stability when 4 slots are populated as it has newer imc. Something like 5700 or 5700x and if you game a 5700x3d. The spped uplift is HUGE, just from the extra cores alone, that's not including faster clocks, faster boost speeds and IPC uplifts from several generational iterations.

Memory controller is on-chip with Zen, so bumping upto a newer chip like a 5600 or similar will potentially help, but the 3xx/4xx chipsets weren’t the best in terms of memory stability. Generally you had to run a little slower to get 4 sticks working, but basically if that’s what you want to do, just buy the same again.
