The 6 Best Motherboards With 8 RAM Slots in 2023

Motherboard With 8 RAM Slots

I updated this article in June after checking for any new releases in 2023. That said, there haven’t been any new 8-slot boards since early 2022.

Today’s 8 RAM options run on HEDT chipsets that are a few years old. These are still very powerful for niche requirements but will have some diminishing returns compared to modern mid-range chipsets (e.g. the below picks have limited Intel processor and DDR5 compatibility).

With that in mind, unless you were aware of these limitations before even reading this article and know what you’re doing, I would highly recommend any builder serious about high-end performance checking out out my premium E-ATX motherboard feature. The top few picks in this article include options that not only boast support for more modern CPUs/GPUs, but also DDR5 support up to 192GB. Even for memory-focussed users, this combo will nearly always outweigh DDR4 @ 256GB.

If you told me there would be motherboards with 256GB RAM support 20 years ago, I would have laughed at your funny joke.

And yet, here we are!

AMD and Intel’s innovations have come so far that there are now premium offerings that boast 8 DIMM slots capable of up to 32GB each.

While the average user does not need this amount of RAM, if you’re building a serious setup for production, hosting, or the most powerful PC you possibly can, then this capability could really take you to the next level.

Today’s feature is here to guide you through the best motherboards with 8 RAM slots. These are premium offerings with lots more going for them than just the RAM, too.

MSI Creator TRX40

Best AMD Motherboard With 8 RAM Slots: MSI Creator TRX40

We’re starting with AMD in no particular order (both leading manufacturers are kings in the high-end desktop space, though AMD is a great choice for those after a CPU with the most cores).

The MSI Creator TRX40 is a fantastic offering. While no mobo with 8 ram slots is cheap, this option achieves a great sweet spot; balancing most of the features you expect in a premium motherboard, while not carrying the 4-figure price tag some HEDT hardware can creep up to.

This Threadripper motherboard doesn’t just boast 8 RAM slots but also supports up to 256GB DDR4 RAM.

Don’t assume this is the case for all 8-sotted offerings, many only go up to 128GB/even 64GB in some budget cases.

What’s more, its JEDEC RAM capacity allows you to achieve 256GB RAM @ 3200MHz, this is an insane speed for this quantity of JEDEC which we would often expect to be bottlenecked further at these amounts.

This is an E-ATX motherboard, with an incredible level of power drawn across the board. With a Threadripper CPU and powerful GPU/s, we can’t imagine any builder, be it for rendering, gaming, or other high-end needs, would be left wanting more power than a build on this motherboard could offer.

Speaking of GPUs; with 4x PCIe 4.0 x16 slots and compatibility for 3-way Nvidia SLI or 3-way AMD Crossfire GPU setups, the amount of graphical capability here is insane. I’m really impressed by MSI’s ability to balance the power draw between the RAM, CPU, GPU, and other onboard features.

The motherboard excels storage-wise too, with 6 SATA 6Gb/s ports & up to 3 M.2 storage slots. I expect this to be a decent option (alongside a premium PC case with high storage capacity) for those after a server motherboard or one for virtual hosting.

On the notion of overclocking your key specs; the Creator TRX40 also lives up to its HEDT name. With plenty of heatsinks operating through the board to maintain appropriate thermal control.

You might not have the bells and whistles of our pricier picks below. But relative to many other options on the market, you can get expect to achieve some impressive speeds.

It’s also worth touching on the I/O panel port and Wi-Fi/audio availability here too. With a whopping 9 x USB 3.2 type-A outputs (some equipped for Flash BIOS use also), a 20G USB type-C port, in-built Intel Wi-Fi 6/bluetooth, Realtek ALC1220 Codec/outputs for high-quality 7.1 audio & 10G Super LAN. 

The inner connectivity is equally impressive, with tonnes of 4-pin fan connectors, ARGB/RGB headers, and all the other ports you’d expect.

What else is there to say? Not only is this the best motherboard with 8 DIMM slots for AMD builders, but it’s an offering that excels in all the categories HEDT users demand.

If you’re looking for the most power possible without getting into nearly 4 figures for your motherboard alone, this is an incredible choice.

Our Rating: 9.5/10

ASUS ROG Strix X299-E Gaming II

Best Intel Motherboard With 8 RAM Slots: ASUS ROG Strix X299-E Gaming II

If you are instead, after an Intel LGA 2066 motherboard with 8 DIMM slot capability, our top pick comfortably goes to this ASUS offering.

Coming in at a very impressive price point for the features, it’s a worthy rival to our top AMD choice.

With its 8 RAM slots also supporting up to 256GB RAM at impressive speeds (or lower quantities at up to 4266MHz). Whether it’s quantity, speed, or a mix of both, you won’t find better RAM capacity at this price point.

With a very impressive set of PCI-e 3.0 x16 slots, you will have the option to install up to 3-way GPU builds with SLI or Crossfire.

ASUS is also a great reliable brand as far as decent BIOs and onboard overclocking software go; often ranking very favorably in benchmarks if you’re after a fantastic OC motherboard.

Another offering with 3 x M.2 slots, the E Gaming II isn’t just great for storage, but also slightly trumps our top AMD pick with an extra 2 SATA ports totaling 8 (6 was already impressive!).

Port-wise, there’s a lot on offer here. With 9 x USB 3.2 Type-A & 1 x Type-C ports, as well as a SupremeFX CODEC S1220A leading its audio ports are perfect for high-quality speakers or headphones. There is little left to desire network connectivity-wise (the LAN port is 2.5G vs our top AMD pick’s 10G, but I don’t expect many users will notice this difference much).

Also for those aesthetic focussed folk, ASUS is a great brand for offering onboard ARGB lighting with the fantastic ASUS ARGB software/onboard headers. I’ve seen these create beautifully illuminated builds alongside an RGB PC case.

Alongside one of the Core-i9 10000X series CPUs in its X299 socket, it’s hard to imagine any type of user wanting more from a high-end build.

At an incredible price for the offering, this is comfortably our top pick for the best Intel mobo with 8 RAM slots.

Our Rating: 9.5/10

Asus Prime TRX40-PRO

Best Budget AMD Motherboard With 8 RAM Slots: Asus Prime TRX40-PRO

Looking for a cheap motherboard with 8 RAM slots feels like a bit of an oxymoron; you’re not going to find the budget options of the mainstream market here.

But with that said, there’s still a huge difference in the price range between the top 8 DIMM options and the cheapest. I’m pleased to say this AMD offering is a very decent choice for those with a tighter budget.

One of the cheapest Threadripper motherboards available today, I’m impressed that the TRX40-PRO still boats 256GB memory support across its 8 DIMM outputs. I expect with the onboard specs, you won’t get quite the same speeds as that of our top AMD pick @ 256GB, but the board will still be capable of a very impressive speed/GB balance when compared to a huge majority of other market offerings.

One of the biggest changes to our more expensive offerings is a slightly reduced power draw to PCIe. With 3 4.0 slots, it’s still a fantastic capability for a budget, but supports a max of 2-way SLI/CLX instead of our main choice’s triple-GPU capability. It’s really up to your if this matters, dual GPUs will still offer incredible utility for most HEDT builds.

The unit still boasts plenty of onboard M.2, VRM, and active chipset thermal protection with its heatsink arrays (alongside the great ASUS UEFI BIOs, you’ll have plenty of customization available).

For storage, we’re pleased to see the TRX40-PRO boasts 3 x M.2 slots and 8 x SATA ports at 6Gb/s; if your prime needs are storage, this may even be a better choice for you than our overall best AMD pick!

Port-wise, you still have a great array of connectivity, with 9 x USB-Type A, 1 x USB Type-C, and decent onboard audio. Compared to our more expensive picks, it’s worth noting the outputs are slightly less capable, with only 3 of the Type-A USB ports being 3.2 Gen 2 (we expect most users will be fine balancing their needs here though).

There is no included Wi-Fi or Bluetooth onboard. We expect this has been done to achieve both the fantastic price and also minimize the power draw. If you do need these, a good Wi-Fi card and Bluetooth adapter will do the job just fine.

The budget hasn’t compromised on headers either, with decent fan, RGB & ARGB connectivity.

If the reduced ports, no Bluetooth/Wi-FI, missing third GPU capability, and slightly lower expected RAM speeds don’t bother you much, know I very nearly made this our top overall AMD pick. It’s great for the price and I was impressed by the performance I saw from it.

Our Rating: 9.25/10

GIGABYTE X299X AORUS Master

Best Budget Intel Motherboard With 8 RAM Slots: GIGABYTE X299X AORUS Master

Although our top pick is already a very cheap 256GB motherboard offering, there’s another compelling option in the AORUS Master.

Previously highlighted on our E-ATX motherboard feature, I consider it one of the best HEDT options on the market and have reviewed some fantastic builds operating on it.

Let’s start with one of the most impressive capabilities of the X299X; its PCIe bandwidth is capable of 4-way GPU builds (with a 48-lane CPU).

You’d be forgiven for thinking this means it’s better than many of our pricier offerings, and for those focussed on graphical capability, it’s a very compelling choice!

RAM-wise, the system still boasts the ability to support 256GB RAM (we expect slightly lower speeds than the top overall/high-end Intel choices, but not significant in the grand scheme of things). Bear in mind that if your CPU is <48 lanes, the maximum support will be 128GB RAM (still a fantastic amount even for a production machine).

Port-wise, the motherboard is still plenty equipped with 9 x USB 3.2 Type-A and 1 x Type-C. The audio codec is a little more basic than our higher ends choices but still capable of great sound output to the average listener (especially with a good pair of headphones). We’re happy to see the board still includes Wi-Fi and Bluetooth too.

The inner connectivity is still good, with plentiful fan headers and outputs for the front I/O panel.

The only thing to reiterate is that to access its 4-way GPU capability, and many other features (including 256GB RAM instead of 128GB max) the motherboard requires a 48-lane CPU to draw from.

That’s the secret to the X299X, part of its lo
