MSI B660 DDR4 BCLK Overclocking Support Incoming?

According to a new leak, MSI might soon release the MAG B660M Mortar Max WiFi DDR4 motherboard with an external clock generator made by Renesas.

A few months ago, der8auer discovered that motherboards with an external clock generator unlock BCLK overclocking of Intel’s non-K (locked multiplier) Alder Lake CPUs. With the right settings, even a Celeron G6900 could be overclocked from 3.4 GHz to over 5.3 GHz.

The MAG B660M Mortar Max WiFi DDR4 changes that, as can be inferred from its rather-lengthy name. Another advantage of the external clock generator is that it adds PCIe 5.0 support for the first expansion slot, something all of the other B660M Mortar models lack (confusingly, there are already four variations out with DDR4/DDR5 and each with/without WiFi).

If you want to use a large supercooler like the Noctua NH-D15 in your build, be prepared for it to cover all the DIMM slots as well as the M.2 socket closest to the CPU socket.

Four DIMM slots are great. Let me remind you that Alder Lake chips support up to 128 GB of DDR4 RAM. The maximum effective frequency of the modules is 4800 MHz – as indicated in the characteristics of the “Mortar”. True, the work of RAM is accompanied by a number of nuances, which will be discussed later. more @ 3DNews (Russian)

MSI Z690 & B660 Roundup – Tech Testers

Although we started working with the DDR5 version ourselves, it appears that it is hardly for sale in the Netherlands, while the DDR4 variant is readily available, normally for just under 200 euros. Exactly the same board in every way, but with DDR4 memory support which just makes more sense at the moment. Now 200 euros still seems like quite a lot of money for a motherboard if you haven’t built a new PC for a while, but in 2022 that is about the starting point for a decent middle-class board.

MSI MAG B660M MORTAR WIFI DDR4 – Overclockers Russia

You already have to come to terms with the fact that you can’t wait for affordable boards in the near future, and it’s better to prepare 15-20 thousand rubles for a mid-level board for processors capable of overclocking, and if this is not necessary, then you can save money and take a cheaper board. Fortunately, devices based on the Intel B660 and H610 chipsets have already begun to appear. At MSI, usually the most affordable models belong to the MAG (MSI Arsenal Gaming) line.

The MSI MAG B660M Mortar WiFi DDR4 features a duet VRM design with 12 power stages, PCIE 4.0, and two M.2 sockets. To round out the experience, the B660M Mortar WiFi also offers great connectivity with WiFi 6 technology, 2.5G LAN, and USB 3.2 20 Gbps for those who need to transfer data quickly. There is a lot to cover in this review, so let’s take a closer look at what the MSI MAG B660M Mortar WiFi DDR4 has to offer.

Everything that you would actually want from a solid, mainstream gaming PC is present and correct here. There’s a full, reinforced x16 PCIe 4.0 slot for the GPU, another full length slot running at x4, and then a final, short x1 PCIe 3.0 slot. Few of us overclock, so that’s not really a miss here, and few have more than one M.2 SSD either. The fact you get a pair of PCIe 4.0 M.2 slots for your drives (one from the chipset and one from your Alder Lake CPU) will be plenty for most users.

About two months behind the flagship Intel Z690 released in November last year. Three new chipsets for the 12th generation Intel Core processor have debuted. This time, we will take up “MAG B660M MORTAR WIFI DDR4” by Micro-Star Int’l Co., Ltd. (MSI / Headquarters: Taiwan) , which adopts the Intel B660 in the middle . While in the middle range, we will thoroughly verify the attention model with abundant functions comparable to the high end.

MSI MAG B660M MORTAR WIFI DDR4 – GreenTech_Reviews

MSI MAG B660M Mortar WiFi DDR4 is a low-cost mATX motherboard based on the Intel B660 chipset, focused on building a mid-sized system, but without the special restrictions, as would be the case with a mini-ITX board. The heroine of this material offers us the possibility of assembling a gaming or working system from high-performance components, but taking into account the limitation in the form of the lack of overclocking of the processor (there are practically no limitations in memory) and a somewhat smaller (relative to ATX solutions) set of slots and interfaces.

Starting with the motherboards, as usual MSI’s been on their game by quickly sending over the MAG B660M Mortar WiFi DDR4 and as it stands this is the only B660 board we have for testing, so we’re happy to have it. The rest of Intel‘s partners seem to have gotten into the holiday spirit, forgetting that this launch is happening. But no matter, the B660M Mortar WiFi DDR4 is a great starting point and is ideal for showing off the new Core i7-12700.

B660 should be a fantastic addition to motherboard lineups depending on vendor choices. For MSI, the MAG B660M Mortar is a well-made solution that sports enough connectivity between USB 2.0 and USB 3.2 for most consumers to be happy. I do like that 2.5Gbe has stayed on as a platform feature with B660 and enjoy that MSI has added Wi-Fi even if it’s the older Wi-Fi 6 standard and not 6e.
