Choosing a Minisforum PC by Memory Size starts with the number each model lists, from 64GB on the MS S1 MAX to 256 GB on the MS 02 Ultra. The guide compares five models priced from £669 to £6,679, with two MS S1 MAX editions priced £1,160 apart. It also covers dispatch warehouses, returns and warranty checks.
Key Takeaways
- The 64GB MS S1 MAX lists its memory as onboard, so size must be chosen upfront.
- MS 02 Ultra has four DDR5 slots, with ECC memory on the Ultra 9 285HX only.
- Lowest AI X1 Pro 470 and MS 02 Ultra prices are Barebone options without an OS licence.
- The 128GB edition and the P495 dispatch from the HK Warehouse, so check shipping details.
Memory size is the first number to check when choosing a PC for AI at home, and Minisforum puts it in the names of two of its AI editions. The MS S1 MAX is sold as a 64GB Local AI Pilot Edition and a 128GB Max AI Compute Edition, and the UK store groups its AI models under an Ultra AI Series menu. Minisforum, founded in 2018, lists other memory sizes across its range. This guide does not say how much memory any AI model needs. It sticks to the memory sizes Minisforum lists.
Why Memory Size Is the First Number to Check
This guide sorts Minisforum’s AI range by memory, not by processor name, because memory is what Minisforum puts forward in its edition names and press text. The MS S1 MAX is named by memory: a 64GB Local AI Pilot Edition and a 128GB Max AI Compute Edition. Minisforum’s press text for the MS S1 MAX P495 goes higher, with “192GB RAM for Local AI”. The AI X1 Pro 470 works differently, with its Radeon 890M offering 2GB to 48GB of VRAM allocation. The MS 02 Ultra takes up to 256 GB of ECC memory.
These are not the same kind of memory, so they do not sit on one scale. Check what each figure refers to on the product page, whether RAM, a VRAM allocation or ECC memory, before comparing them.
Minisforum’s Memory Sizes at a Glance
| Product | Memory figure as Minisforum words it | UK price shown | Source |
| AI X1 Pro 470 | Radeon 890M with 2GB to 48GB VRAM allocation | £669 | UK store (price); CES 2026 press release (memory) |
| MS S1 MAX 64GB Local AI Pilot Edition | 64GB, as named | £2,359 | UK store |
| MS S1 MAX 128GB Max AI Compute Edition | 128GB, as named | £3,519 | UK store |
| MS S1 MAX P495 AI Compute Edition Workstation | “192GB RAM for Local AI” | £6,679 | UK store (price); Minisforum About page press text (memory) |
| MS 02 Ultra | Up to 256 GB ECC memory | £1,039 | UK store (price); CES 2026 press release (memory) |
These rows are not a ranking, because the figures are three different kinds of memory: a VRAM allocation, RAM and ECC RAM. The type of memory behind the 64GB and 128GB names: Information could not be verified. The MS 02 Ultra figure comes from the press release for the newer version, so confirm the UK listing matches before you rely on it.
64GB or 128GB: Two MS S1 MAX Editions Side by Side
The two MS S1 MAX editions on the UK store sit a clear step apart in price.
- 64GB Local AI Pilot Edition: £2,359, with a regular price of £2,949 shown.
- 128GB Max AI Compute Edition: £3,519, with a regular price of £4,399 shown.
- Price gap: £1,160 between the two prices shown.
The names differ by more than the memory figure, with “Local AI Pilot” on one and “Max AI Compute” on the other. Whether memory is the only difference: Information could not be verified, so compare the full specification lists on both product pages before you decide.
Wikipedia, citing TechRadar, says the MS S1 Max was announced in May 2025 with the AMD Ryzen AI Max+ 395 and reported as the first computer with dual USB4 v2 ports. Confirm on the product page that the UK editions match those details.
Going Higher: The MS S1 MAX P495 and Its 192GB Claim
At the top of the range sits the MS S1 MAX P495 AI Compute Edition Workstation, priced at £6,679 with a regular price of £8,349 shown. Its memory figure comes from Minisforum’s own press text on its About page, which describes it with “192GB RAM for Local AI” and lists “131 Overall TOPS”. The page gives no date for that text.
These are Minisforum’s own claims, not tested results. The rest of the specification, including the processor: Information could not be verified. Read the full product page before you decide whether this tier is worth the step up from the 128GB edition.
Starting Smaller: The AI X1 Pro 470 and Its VRAM Setting
The AI X1 Pro 470 is the lower priced entry point, at £669 with a regular price of £839 shown. Minisforum’s CES 2026 press release describes it as powered by the AMD Ryzen AI 9 HX470, with Radeon 890M graphics and a VRAM allocation of 2GB to 48GB. It also lists storage of up to 12TB and an OCuLink port for connecting external NVIDIA RTX or Radeon RX graphics cards. Minisforum aims it at remote workers, creators, gamers and AI developers.
The UK store lists the name as “AI X1 Pro 470”, while the press release uses “AI X1 Pro 470”. Confirm on the product page that they are the same model before you rely on those specifications.
Room to Grow: The MS 02 Ultra
The MS 02 Ultra is the option for readers who want room to add memory and parts later. It is priced at £1,039, with a regular price of £1,299 shown. Minisforum’s CES 2026 press release describes a 4.8 L mini workstation with up to 256 GB of ECC memory, four M.2 slots and three PCIe slots, built with a pull out structure for easier upgrades. It also lists USB4 v2 at 80 Gbps and dual 25 GbE networking. Chairman Roy Jiang said the company wants to show that “mini” no longer means compromise, citing AI compute among the reasons.
The press release describes the newer version of the MS 02 Ultra. Confirm that the UK listing matches it before you rely on these specifications.

How to Pick Your Memory Size
- Find the number your software asks for. Memory needs differ by program, so check the requirements of the software you plan to use.
- Match it to a tier. The MS S1 MAX comes at 64GB (£2,359), 128GB (£3,519) and 192GB (£6,679), the AI X1 Pro 470 lists up to 128GB, and the MS 02 Ultra lists up to 256 GB.
- Check what the figure means. The MS S1 MAX lists unified LPDDR5x memory, the other two use DDR5 SO DIMM slots, and ECC applies only to the MS 02 Ultra with the Ultra 9 285HX.
- Check whether memory can change later. The MS S1 MAX 64GB page lists its memory as onboard, while the AI X1 Pro 470 has two memory slots and the MS 02 Ultra has four.
- Compare like with like. The AI X1 Pro 470 (£669) and MS 02 Ultra (£1,039) are Barebone prices, and the 32GB versions start at £1,215 and £1,545.
Price, Shipping, Returns and Warranty Before You Order
At £2,359 to £6,679, the policy pages are worth reading before you pay. Minisforum’s homepage banners list 30 Day Easy Returns, a 2 Year Quality Guarantee and Lifetime Technical Support. The shipping and refund policies published on Minisforum’s global store go further. They set UK free shipping at orders over £70, with £12 below that, and say the recipient pays any customs duties and taxes. They allow a return request within 30 days of receipt but exclude sale items, and every price in this guide is a sale price, so that exclusion may matter.
These pages are on the global store, and whether they apply to UK orders: Information could not be verified. Return shipping cost, restocking fees and the warranty terms: Information could not be verified.
The dispatch warehouse also differs by model. The MS S1 MAX 64GB edition, AI X1 Pro 470 and MS 02 Ultra list the UK Warehouse, while the 128GB edition and MS S1 MAX P495 list the HK Warehouse. Read the Shipping Policy and Warranty & Return pages on the UK store before checkout.
Current Offer
Minisforum’s homepage runs a Halloween Sale, described as deals with multiple free gifts with purchase. Each product in this guide shows a sale price beside a regular price, such as £2,359.00 against £2,949.00 for the MS S1 MAX 64GB Local AI Pilot Edition. Whether those prices are part of the Halloween Sale: Information could not be verified. Gift details, eligible products and terms: Information could not be verified, so check the sale page before you order.
Summary
The guide covered five Minisforum PCs sorted by memory size. These were the AI X1 Pro 470 from £669, the MS S1 MAX 64GB Local AI Pilot Edition at £2,359, the MS S1 MAX 128GB Max AI Compute Edition at £3,519, the MS S1 MAX P495 at £6,679 and the MS 02 Ultra from £1,039. It also noted the Halloween Sale banner on the Minisforum homepage.
The MS S1 MAX line stands out because Minisforum names its editions by memory, from 64GB and 128GB up to 192GB on the P495. The AI X1 Pro 470 takes up to 128GB in two memory slots and has an OCuLink port. The MS 02 Ultra has four DDR5 slots and lists up to 256 GB, with ECC memory on the Ultra 9 285HX version only.
Two checks help most. First, find the memory figure your software asks for, then check what each Minisforum figure means and whether it can change later, since the MS S1 MAX 64GB page lists its memory as onboard. Second, remember that the lowest AI X1 Pro 470 and MS 02 Ultra prices are Barebone options, with 32GB versions starting at £1,215 and £1,545, and that the 128GB edition and the P495 dispatch from the HK Warehouse.
