If you want to run a Skylake E3 Xeon, it needs to be placed in a motherboard with either the C232 or C236 chipsets. This is a change from the last generation, and as a result most of the motherboard manufacturers are bringing some of their consumer expertise to new products in order to get a slice of the casual Xeon user pie. We explored a server-like C236 based motherboard in the previous review, and in this review we’re taking the latest edition from ASRock’s Gaming range, based on the C232 chipset, for a spin.

A Brief Recap: The Skylake Xeon Story
Copied from our MW31-SP0 Review

From a PC-under-the-desk perspective, for several generations Intel has run consumer and server grade chipsets for mainstream processors side by side. Most motherboard manufacturers use a mix of both sets, saving the server grade ones for their B2B sales when dealing with large clients, and offering a few models to individuals that wanted to use both a Xeon processor with ECC memory and required additional support such as IPMI control via an additional network port or an onboard 2D graphics accelerator for quick access. We have reviewed a couple of these over the years, but ultimately they filled that sales niche that required business contracts and overriding stability for mission critical systems. Up until Skylake however, both the consumer and server grade chipset motherboards could use either consumer or server grade processors interchangeably.

This has changed with Skylake. The new Skylake Xeon E3-1200 v5 processor family is locked out of the 100-series chipset firmware. In order to run one of these processors, a user will have to buy a motherboard that supports either the C232 or C236 chipsets. These chipsets are ultimately offshoots of the consumer line, with C236 mirroring the Z170/Q170 platforms and C232 going down the B150 route.

Most motherboards we’ve seen for sale to consumers are C232 based, and will be similarly priced to B150 motherboards. It should be noted that for SLI, only C236 motherboards are supported, and only if the manufacturer has paid the licensing fees to enable it and provided sufficient routing. At present, I’ve only seen two C236 motherboards for sale that are SLI capable.

The thing here is that server chipset based motherboards are unlike consumer motherboards. They are built for function over user experience, often with very consumer unfriendly features such as large complex BIOSes and wording more akin to IT professionals discussing the hardware than a casual buyer. This is going to change slightly as Intel has changed the rule set, and like this review we will see some of channel motherboard-like nature, software and aesthetics coming into the server chipset families.

ASRock E3V5 Performance Gaming Overview

As our first C232 review, and by extension our first ‘B150-like’ review, the E3V5 Performance Gaming is going to come across as a very cut down version of a typical Skylake motherboard that we review. Originally called the E3V5 Performance Gaming OC, before base clock overclocking was given a shiv and told to be quiet, this motherboard brings over a number of ASRock’s Gaming motherboard feature set, with the focus being predominantly on single discrete graphics and the use cases therein. 

There are no onboard video outputs for example, which mirrors the fact that most Skylake E3-1200 v5 series Xeons do not have integrated graphics at all, but it means to use it as an active machine requires a discrete graphics card. The single PCIe slot from the CPU is a PCIe 3.0 x16 and it comes with a PCIe 3.0 x4 slot from the chipset. This means there is no SLI, but CrossFire is potentially capable via the PCIe 3.0 x4 slot. That x4 slot is also available for PCIe SSDs in RAID, or PCIe to M.2 converters, as the motherboard doesn’t have an M.2 slot as part of the design.

Also in the list of things this motherboard doesn’t have: SATA Express and USB 3.1. There are four USB 3.0 ports on the rear and a header to compensate, but similar to other products in this price range, the additional $4-$7 cost of a USB 3.1 controller is a bit too much. ASRock does equip the board with three open-ended PCIe 3.0 x1 slots though, allowing for add-in cards to provide needed ports.

The key element to ASRock’s product is going to be the looks. The E3V5 Performance Gaming is a gaming motherboard with styled heatsinks and a rear IO cover that keeps the aesthetic. The audio comes in with Realtek’s high-end ALC1150 codec and ASRock has used some of its Purity Sound branding to add in filter caps, EM shields, PCB separation and a headphone amplifier to improve the audio utility. On the networking, Intel’s I219-V does the job rather a Realtek/Killer network chip which is what we normally see on a gaming product.

On the BIOS side we have updated visuals all around, with the BIOS getting the latest makeover from Z170. The software side is disappointing at best – ASRock’s CD package only provides drivers and the APP Shop, requiring users to select which applications from ASRock they want to install: and there’s not a handy ‘quick install’ feature either.

Performance is in the middle ground for a Skylake platform: no MultiCore Turbo means it sits in the lower half in out-of-the-box CPU performance. Our audio tests showed a much weaker ALC1150 implementation than expected, with performance more akin to a Realtek ALC892 or ALC889. USB 3.0 performance was also slower than expected. The plus sides on performance give the E3V5 Performance Gaming a better-than-average DPC Latency, a nice and low power consumption, and an average POST time.

ASRock E3V5 Performance Gaming Overclocking

Even though this motherboard was originally called the E3V5 Performance Gaming OC, the latest motherboard BIOS removes the base frequency overclock options. We did get the motherboard with an earlier BIOS, although results were somewhat inconclusive, resulting in +15% overclock suitable for POST but for some reason only a single memory channel was working. We tried to adjust some settings and try a new processor, but somehow our OS image became corrupted. As a result, especially with the new BIOS policy, we decided not to extensively try and fix the issues.

    The USB 2/3 information in the table on the first page doesn't appear consistent between C236/C232 and Q170/B150. Is it correct? eg the latter lists 10/14 USB3/2 ports reflecting support for 14 USB ports, of which up to 10 can be converted into USB3 ports by combining them with a high speed IO lane from the chipset. The C236 lists 10/4 ports; which is the distribution you'd get if using 10 HSIO lanes to make the max number of USB3 ports. However putting it in the table like that implies that the 10 lanes are locked into USB3; which strikes me as odd, since for server/workstation uses SATA/PCIe/m.2 seem like they'd be more generally useful than lots of USB3.

    Apparently you can slap "performance-gaming" even on a product based on a cut down B150 with Xeon support. This is one way to devalue this kind of branding.

    @close: "Apparently you can slap "performance-gaming" even on a product based on a cut down B150 with Xeon support. This is one way to devalue this kind of branding."

    The mentality is a little different than that. They think you can slap "performance-gaming" on anything with overclocking features. Putting aside the fact that these are two different markets, they had the unfortunate lack of foresight to predict that Intel would shut the new fangled Xeon overclocking features down. Now the board no longer fits even their definition of "performance-gaming", but their is no way for the average consumer to know that. They should have rebranded the product. Instead, they've done exactly as you said, devalued the branding.

    To be honest I only spotted the "OC" part after I posted the comment. Waiting for the "Gaming-Performance-OC-Megatron stick in the mud" edition.

    Actually I have this motherboard and a E3 1275 V5. You can still OC on the very first BIOS (v1) or on the beta BIOS 1.3. Enjoying a 4.5GHz Skylake Xeon.
  • Zarok001 - Wednesday, December 28, 2016 - link

    Can I still download this bios anywhere. I was told that this overclocking still works and now im sitting here with a GTX 1070 and a locked Intel Xeon E3-1245v5, i mean it boosts up to 3.9Ghz but i would love to overclock it.
  • BrokenCrayons - Thursday, May 5, 2016 - link

    Let's face it, the branding doesn't have much value anyway at this point regardless of what ASRock does to it. It's silly to stick numbers into words these days as is done with the 1 in the word Fatal1ty. That just comes off as 1990's era childish. "Performance-gaming" is just marketing speak that is intended to appeal to a targeted audience of potential buyers in order to enable an exchange of money and products. The same is true of the color scheme the vendor selected, some of the "features" of the motherboard itself, and licensing the use of a now unknown crusty old "pro gamer." In order to charge a price premium, companies have to ensure their products fit the buyer both in actual capabilities, perceived benefits, and emotional appeal. It's pretty safe to dismiss the majority of ASRock's marketing materials (and probably for the best in all product purchases in order to make a rational decision) so a potential buyer can assess the actual benefits the product offers.

    And yes, I've been accused of being a buzzkill more than once. :)

    So this is the weird byproduct of Xeon overclocking being discovered? But since Intel slapped down all the board manufacturers this is now an effectively useless product?
  • jasonelmore - Wednesday, May 4, 2016 - link

    Intel just doesnt wanna sell the new gen CPU's with OC and ECC..

    tons of people wanna build a skylake nas box with ECC for freenas, but intel is making it very hard to do this without buying a integrated board with a bunch of atom cores. We want the OC for VM performance, while still keeping ECC
  • StrangerGuy - Thursday, May 5, 2016 - link

    I for one, is still amazed that people expects overclocking free lunches from Intel in year 2016 like they are still living in 2007.
