ASUS Strix Z270E Gaming Motherboard Review

Subject: Motherboards
Manufacturer: ASUS

Overclocking and Conclusion


To give a feel for the overclocking performance potential of the Strix Z270E Gaming motherboard, we attempted to push it to known CPU-supported performance parameters with minimal tweaking. At the stock base clock speed of 100Mhz, we pushed the CPU to 5.1GHz with a 4.8GHz ring bus and 3866MHz memory speeds. This was done at a 1.34V CPU voltage and a 1.35V memory voltage with all other values left at default settings. However, the board refused to stabilize at any memory settings about 3867MHz, even though the modules are rated for and have run at 4000MHz on other boards. The highest base clock speed the board would run at was 167MHz, equating to a 5.0GHz CPU speed, 4.8GHz ring bus, and 3672MHz memory speeds. All overclocking sessions remained stable for over 4hrs. System stability was tested running the AIDA64 stability test in conjunction with EVGA's OC Scanner X graphical benchmark running at 1280x1024 resolution and 8x MSAA in stress test mode. Note that 16GB (2 x 8GB) of Corsair Vengeance LPX DDR4-2666 and 8GB (2 x 4GB) of Corsair Dominator Platinum DDR4-4000 memory modules were used for the overclocking tests.

Note that this is is meant only as a quick preview of the board's performance potential. With more time to tweak the settings to a greater extent, pushing to a higher base clock and ring bus speed may have been achievable, in addition to an overnight stability run without issue.


As of March 27, the ASUS Strix Z270E Gaming motherboard was available at for $209.21 with Free shipping. The board was also available from for $189.99 and from B&H for $189.99.

ASUS continues to differentiate its product lines, expanding their Strix gaming product line with the Strix Z270E Gaming motherboard. The board combines a killer aesthetic with a rich feature set to make for a compelling product. Take into account its performance, and you have a solid product. One of the nicer additions was the support for dual external RGB LED strips, something not many boards has currently. The board performed very well across the board at stock speeds. Its overclocking performance was very good as well with a single caveat - its inability to boot with memory over 3866MHz. However, that issue is most likely fixable via a BIOS update. All in all, a good board with a solid feature set.

Lack of SATA-Express... That's not a con.

I have yet to see one single sata express device on the market.

This board is all positive for me:
- I am happy to see a board WITHOUT sata express - A useless added expense
- Could not care less about any RGB lighting - just an unnecessary added expense.
- My Memory will be less than 3866 MHz
So all good

Has Asus completely dropped Alpine Ridge for Z270 ? They had it on the Maximus Formula for Z170.

For this board, it looks like it, but not sure about the rest of them...

Haven't been able to find one... maybe it's unjustified, but for me Asmedia and premium don't go together.

ASUS supports TBIII via theThunderbolt EX III add in card. This is done via firmware and PCH design support. All that is required is connecting the corresponding cable from the TB header to the card and you are good. It is natively on the board due to it's inclusion would considerably increase the cost of the board. It is not on this board but you can at the similar Z270-A if you want support for it or any ASUS board that supports the TB header.

Is the CMOS battery thing a joke?

I see that as a pro or con in every review. At first I thought you were joking, but now I'm thinking you are serious. What a miniscule issue. My current build is 3+ years old and still on the original CMOS battery.

Not a joke, a minor inconvenience and pet peeve of mine. You normally don't have to mess with the battery, but when you do, its a PITA if you have to take apart half your system to get to it...

Remember having to do this last year on an older system it really was a pain!

Looks like a lot of reviewers are liking the Strix z270e, have read a few and they all seem to speak highly... Off to amazon I go :)

This is perhaps the worst review I've seen on this site. Hopefully it was from an unpaid freelancer.

DVI? really? be done with it already!
