Asrock B660 Metal Legend – Overview 2022


Whereas avid gamers and energy customers could also be the obvious advertising and marketing section for {hardware} producers, their whole quantity falls far under the mainstream enterprise and residential customers. The Metal Legend line is usually aimed toward workplace and productiveness customers, although Asrock outfits it far above a strictly “enterprise solely” trim. With its motherboards, fancy PCB design and RGB lighting is included, not issues that normally rank excessive on the workplace precedence listing. However who says productiveness customers don’t respect beauty? The complete ATX model of the B60 Metal Legend has an MSRP of $149, which means stiff competitors from different strong and well-rounded boards. It is a competent sufficient choice for Intel LGA1700 CPUs, however we would prefer it extra at a Jackson or so much less.


Board Design

As talked about above, the Metal Legend could also be meant for “boring” productiveness work, however the board itself is quite eye-catching. The board makes use of what may be best described as an arctic digital camouflage motif, gray and white silkscreening over the black PCB.

Contrasting brushed and bead-blasted floor finishes proceed the design on the aluminum heatsinks. For added model, RGB lighting is embedded within the entrance edge spelling out the Metal Legend identify and emblem. Included within the field are additionally a Metal Legend keychain, a Metal Legend emblem keycap for mechanical keyboards, and two hook-and-loop straps for cable administration.


Fast Recap: The Z690 vs. B660 Chipsets

These unfamiliar with the variations between Intel’s 600-series chipsets can learn our detailed breakdown right here. Whereas it’s honest to say most customers gained’t discover any distinction between Z690 and H670 boards, aside from overclocking, the B660 chipset has drastically diminished storage choices that must be thought-about.

PCI Categorical (PCIe) and SATA lanes are minimize in half in comparison with Z690, leaving a most of six PCIe 4.0 lanes, eight PCIe 3.0 lanes, and 4 SATA 6Gbps ports. For the reason that CPU already has its personal PCIe 5.0 x16 and 4.0 x4 lanes for the first growth card and M.2 storage drive, B660 boards will almost definitely use their 4.0 lanes for a for a second 4.0 x4 M.2 slot. Nevertheless, the eight 3.0 lanes shall be very restricted to cowl extra PCIe storage, peripherals, and growth card slots. Anticipate most B660 boards to have restricted growth choices, restricted bandwidth for gadgets, a number of gadgets sharing connection lanes, or all of the above. RAID assist over PCIe has additionally been minimize, although SATA RAID continues to be supported.

On high of that, the B660 has solely 4 DMI 4.0 lanes connecting it to the CPU, whereas each Z690 and H670 have eight. Because the DMI carries all storage and peripheral site visitors from the chipset to the CPU, this could possibly be a big bottleneck. A single PCIe 4.0 x4 drive may saturate the DMI by itself. Add SATA drives, USB gadgets, and growth playing cards onto the bus, and you’ll see the potential drawback.

USB 3.x lanes are nearly similar to H670, so not a lot is misplaced there that can have an effect on mainstream and enterprise customers. The utmost depend of USB 2.0 ports is diminished from 14 to 12, and 5Gbps USB ports drop from eight to 6. Two 20Gbps and 4 10Gbps USB ports are nonetheless available for high-speed exterior gadgets.

Now, stress assessments on a bench don’t at all times replicate real-world use, so this isn’t all doom and gloom. B660 is commonly a decrease mainstream and enterprise resolution. Utilizing a number of PCIe storage drives is unlikely in such a job. When solely utilizing a single PCIe drive, the DMI has loads of bandwidth for a number of SATA drives, Ethernet site visitors, and a high-speed USB drive. If all 4 SATA ports hosted high-performance SSDs, and several other USB 3.2 ports had been in use (significantly each 20Gbps ports), the DMI could possibly be a bottleneck. However realistically, the B660 DMI gained’t be a limitation as long as you solely use one NVMe drive by way of the CPU.


CPU and Reminiscence

With out CPU overclocking assist, the VRM makes use of an understandably modest nine-phase design and solely a single 4+4 EPS connector. The Metal Legend formally helps 125-watt and 150-watt Core i7 and Core i9 CPUs, even when it’s unlikely to be achieved a lot within the wild. You’ll want to hold correct airflow throughout the VRM heatsinks should you set up one of many higher-end CPU SKUs on this board.

Asrock selected to stick with DDR4 on the Metal Legend, becoming for its meant use. The B660 chipset nonetheless helps RAM overclocking. One particular Kingston DDR4-5333 package is listed on the QVL, although most are DDR4-4600 or beneath.


Growth, Storage, and Rear I/O

Additional connectivity takes some unusual turns because of the B660 chipset’s restricted connection lanes. Two full-length PCIe slots can be found, with the highest slot as traditional connecting to the CPU at 5.0 x16 charges. The opposite is restricted to 4.0 x2. The remaining two PCIe slots are open-ended and assist 3.0 x1 connections.

The board has three M.2 slots. The highest one, above the primary PCIe slot, has a warmth defend with thermal pad and connects on to the CPU at 4.0 x4 bandwidth. The second slot is restricted to a 3.0 x2 connection, however it may additionally function in SATA mode. The final is under the chipset and operates at 4.0 x4. All three slots will match 60mm and 80mm drives, whereas the third slot can maintain as much as 110mm drives.

Regardless of the B660 chipset being restricted to solely 4 SATA ports, the Metal Legend has six. Asrock added an ASM1061 controller for the additional two ports. Two are alongside the underside edge, perpendicular to the board, and the opposite 4 are alongside the entrance edge by the chipset heatsink, dealing with ahead. The second M.2 slot and first SATA port share lanes, so the 2 can’t be used concurrently in SATA mode.

The I/O on the ASRock B660 Steel Legend

The rear I/O is pretty plain. On the highest is a keyboard and mouse stack, with one PS/2 port and two USB 2.0 ports for primary peripherals. The 4 blue USB ports are all USB 3.2 Gen 1 5Gbps, and the lone Kind-C port is USB 3.2 Gen 2 10Gbps. For onboard graphics, an HDMI 2.1 and DisplayPort 1.4 are there.

The Metal Legend does have BIOS Flashback functionality, and a management button for that by the USB ports. Onboard audio is offered by a RealTek ALC897 codec, with the same old 5 3.5mm jacks and one fiber optic connector. For networking, as an alternative of utilizing the built-in chipset community controller, a RealTek 2.5Gbps RTL8125BG is used. No Wi-Fi is offered onboard, however a devoted Wi-Fi M.2 slot is under the third PCIe slot, and the rear I/O defend does have cutouts for mounting antennas.


Inside Connectors and Format

Three four-pin fan headers and two addressable RGB headers are within the high proper nook of the board. The RGB lettering down the entrance edge takes up a good quantity of house, pushing the 24-pin ATX energy connector and two USB 3.2 headers, one 2×2 20Gbps and one 10Gbps, again towards the RAM sockets. Under the highest 4 SATA ports is one other fan header.

The headers alongside the underside edge are what you’ll anticipate: HD Audio, and two extra RGB headers (one generic addressable, one Asrock Polychrome suitable). Six fan headers can be found for cooling use, one simply above the CPU socket, one by the first M.2 slot, and the remainder scattered down the entrance fringe of the board. Happening the entrance edge, you will discover two addressable RGB headers, a POST standing LED cluster, the 24-pin ATX energy connector, and an odd association of USB 3.2 headers. The Riptide has the anticipated USB 3.2 Gen 1 header, and even a 2×2 20Gbps connector, however the second Gen 1 header is shocking, much more that it is ahead dealing with.

The remainder of the interior connectors alongside the underside edge are fairly normal fare: HD Audio, two extra RGB headers (one generic addressable, one for Asrock Polychrome Sync), TPM, two USB 2.0 headers, two fan headers, a transparent CMOS jumper, the front-panel-connection cluster, and the opposite two SATA ports.


The Construct Expertise

Because the B660 Metal Legend was meant primarily for productiveness use, assessing the structure requires a distinct outlook. However actually, there aren’t any surprises right here. The VRM heatsinks go away loads of room for even massive CPU coolers, which seemingly gained’t ever be used on this board. We at all times need extra fan headers in additional locations on a board to make it as handy as attainable for fan placement in a case, however the seven fan headers it already has needs to be ample for any cooling this board will want. Additionally unlikely is utilizing any growth card within the backside slot, so no headers there shall be blocked.

Maybe the one annoyance, given the Metal Legend’s worth and meant market section, is inserting the primary and second SATA ports on the underside fringe of the board. Utilizing these ports makes SATA cable administration not fairly as modern as it may be if the forward-facing ports are used. There may be, in fact, no hurt in utilizing the opposite ports, nevertheless it may be a nagging drawback to extra fastidious customers preferring to connect drives in ascending order.


A Transient Take a look at the UEFI BIOS

The Metal Legend’s UEFI makes use of a digital camouflage sample as a background to match the graphics on the board, however in any other case it’s the identical as different Asrock boards. As we’ve already coated it in-depth in different opinions, we gained’t spend a variety of time reiterating the main points right here.

By default, getting into the UEFI defaults to EZ mode the place you possibly can handle practically the whole lot you may must on this board since overclocking and tweaking choices are restricted. Making use of reminiscence XMP profiles, altering drive boot order, updating the firmware, and altering the system fan profiles are all obtainable.

The Superior Mode is accessible if you wish to specifically tune your RAM settings, set configuration profiles, monitor storage drive specifics, change CPU energy settings, or use the safe erase utilities for flash drives. All this you are able to do at native FHD resolutions as an alternative of stretched 1,024-by-768 shows, because of Asrock’s assist for prolonged show resolutions.

To customise the RGB lighting of the board and linked gadgets, Asrock features a pretty strong Polychrome utility instantly inside the UEFI. Whereas many boards restrict RGB customization inside the UEFI to a couple presets, the Metal Legend permits full configuration for colours and patterns to particular person headers and gadgets or all collectively.

Additional Utilities

The Metal Legend makes use of Asrock’s typical group of Home windows utilities to permit the consumer to tweak the motherboard with out getting into the UEFI. The App Store exhibits obtainable software program and utilities to your specific motherboard and consists of an Replace part for downloading drivers. Mixed with the built-in Ethernet driver within the UEFI, it permits new builds to get up to date shortly and operating easily.

The A-Tuning software continues to work because the efficiency and overclocking utility for the motherboard. A number of the extra obscure energy and voltage settings are accessible solely from the UEFI, however practically the whole lot else is mirrored right here. The B660 can’t overclock a CPU, in fact, however you possibly can improve the stepdown multipliers as much as the CPU’s most to maintain the cores operating as quick as attainable when a number of cores are in use. Fan auto-tuning, five-point curve profiles, and system surroundings monitoring are additionally right here.

Verdict: Preserve B660 Fundamental

A lot of this evaluate has been looking for new methods of claiming “pretty typical,” “as anticipated,” and the like (typically in a great way, typically not). Typically, it’s a optimistic when merchandise don’t shock you, as a result of it means they meet expectations. Nevertheless, the B660 Metal Legend additionally has an atypically excessive MSRP. chunk of that worth improve undoubtedly comes from the added SATA and a pair of.5Gbps Ethernet controllers. However do these additions deliver sufficient performance and worth to warrant their inclusion?

The ASRock B660 Steel Legend

Maybe having solely 4 SATA ports might look dangerous in comparison with equally priced H670 boards with as many as eight. However what number of workplace desktops being constructed now want greater than 4 SATA drives? Equally, it’s fancy to say your motherboard helps 2.5Gbps Ethernet, however these ports require a 2.5Gbps-capable community to be of any use.

Most customers anticipate B660 motherboards to price lower than H670 boards. It’s comprehensible for a full-featured B660 to price greater than a stripped-down H670. However the issue the B660 Metal Legend faces is that it prices greater than some superb H670 boards, not least of which is its personal stablemate, the H670 PG Riptide. In comparison with the Metal Legend, the Riptide has the identical CPU and RAM efficiency, two extra USB 3.2 ports on the again, and not one of the B660’s storage bottlenecks, all for a lower cost. Exchanging that for a sooner Ethernet controller and two extra SATA ports doesn’t look like a clever commerce for many consumers.

Had this board accepted and labored inside the B660 chipset’s limitations, and actually embraced the thought of a productivity-first motherboard, issues may have been totally different. Begin with the B660 to shave somewhat off part price, settle for that 4 SATA ports are ample for the mission assertion, and cease at two M.2 slots. Work computer systems are effective with common audio jacks; no want for 7.1 rear audio connectors or TOSLINK. The digital camo design can keep, however take away the onboard RGB results. (The RGB headers can go, too, and no want for a keychain within the field.)

Carry that board to market and make it price-competitive, and you’ve got a winner on the LGA1700 low finish. As it’s, this Metal Legend appears to spends an excessive amount of time making an attempt to compensate for its chipset and forgets that typically, a price range chipset is price range for a purpose: to maintain the board primary.
