Default ASUS Gryphon Z87 Review

ASUS Gryphon Z87 is the first The Ultimate Force (TUF) Series board in mATX form-factor.
By default it comes without "thermal shield" but you can order TUF Gryphon Armor Kit separately if you wish.
The price tag is only $170 that makes this board interesting for using in compact PC builds.
It's not ROG board but it still has some features, which is more than enough for daily aircooling OC.
Let see what OC results we can do with this board and Intel Core i7-4770K CPU.

On-board LAN: Intel I217-V Gigabit Ethernet
On-board Sound: Realtek ALC892 7.1+2 Channel HD-Audio Codec
USB 2.0: 4x ports in back panel + 4x internal ports (using Intel Z87 PCH)
USB 3.0: 4x ports in back panel + 4x internal ports (using Intel Z87 PCH)
IEEE 1394 support: none
System monitoring: Nuvoton NCT6791D and Nuvoton NCT7802Y
Power connectors: 1x ATX 24-pin and 1x 8-pin EPS12V
Board size: 244x244-mm
Form factor: mATX
Price: $170 USD

Box and accessories

ASUS Gryphon Z87 comes in compact box not so much bigger than the board itself:

(click on any picture to see full size version)

Back side of the box shows some of features supported by the board:

Items bundled with the board:
- User guide;
- 5 year warranty notice;
- Certificate of reliability;
- Driver and software DVD;
- Back panel I/O Shield;
- SATA 6 GB/s cables (4 pcs);
- Flexible SLI bridge;
- ASUS Q-Connectors;

PCB design and features

Board size is standard 244x244-mm mATX.
It has seven fan connectors - 6x 4-pin and 1x 3-pin. Connected fans can be controlled in the BIOS and ASUS AI Suite III.

Front side of the board:

Back side of the board:

ASUS Gryphon Z87 without heatsinks:

The board uses Socket 1150 by Foxconn:

This CPU socket supports Intel Haswell-based Core i5/i7 CPUs

There is 4x slots for DDR3 RAM with dual channel support:

And four PCI Express slots for expansion cards (two PCI-E x16, one PCI-E 4x and one PCI-E 1x):

Back panel interfaces includes:
- 4x USB 2.0 ports
- 1x DVI-out
- 1x HDMI-out
- 1x optical SPDIF-out
- 4x USB 3.0 ports
- 1x LAN interface
- 6x in/out 3.5-mm mini-jack for HD Audio Codec

All six SATA ports can works at 6 GBps speed.
Now we can use up to 6x SSD in RAID0 at full speed for PCMark on Intel platform without using some expensive discrete controllers!

Realtek ALC892 - 7.1+2 Channel HD Audio Codec

Intel Z87 PCH

There is two buttons in the low left corner of the board - BIOS_FLBK and DirectKey.
BIOS flashback is recovery feature. Even if current BIOS are corrupted and system won't boot - you can save BIOS image to USB stick, insert it to the board and use BIOS_FLBK button.
DirectKey button can be used for entering BIOS after reset.
Alternatively you can select BIOS option to use DirectKey as Power button.

ASMedia AMS1480 - PCI-Express Gen3 Switch
This switches commutates 8 lanes between first and second PCI Express x16 slots
If second slot is empty all 16 lanes goes to the first slot.
In case if some card installed in second slot - 8 lanes goes to first slot and 8 to second slot.

VRM design

For input power from PSU there is one 24-pin connector

And one 8-pin connector

CPU VRM uses 8-phase design

Vcore-controller is remarked ASUS DIGI+ APS1251 (I guess it's some sort of CHiL Semiconductor)

There is 8 pairs of ON Semiconductor NTMFS4937N+NTMFS4955N Power MOSFETs and 4 International Rectifier IR3535MPBF drivers:

Memory VRM is 2-phases and uses ASUS DIGI+ ASP1103 controller


ASUS Gryphon Z87 uses two heatsinks. First of them covers MOSFETs of CPU VRM.

Another heatsink cools Intel Z87 PCH

VRM heatsink uses one copper heatpipe. PCH heatsink is fully aluminium.

They used 6 screws to mount on motherboard.

VRM heatsink stays cool even if system is overclocked.
PCH heatsink more hotter than VRM heatsink, but temperatures still in safe range.

UEFI BIOS features

The board was tested with BIOS version 3009 [24-May-2013].

Overclocking results

10 minutes of LinX testing was used for checking stability.
Stable CPU OC - 4500 MHz only 1.17V.
Ring Bus (Cache) works at 4500 MHz with 1.20V.
As you can see voltages remains the same in idle and loaded:

With higher Vcore CPU temperature goes too high and it start to throttle.
It seems Haswell CPUs needs thermal interface replacement under HSF for overclocking more than 4400-4500 MHz on air cooling, but it is another story.

Minimal voltage to boot Windows at 5 GHz was 1.30V.
CPU-Z valid shows it as 1.31V for some reasons, but it was 1.30V set in BIOS and shows in Windows.
Ring Bus (Cache) works at 4700 MHz with 1.25V.
In this mode CPU can run some benchmarks, except long and multithreaded like wPrime 1024M.

Working BCLK range with default 5/5 REG/DMI ratio (CPU Strap = 100): 100-106 MHz

Working BCLK range with 4/5 REG/DMI ratio (CPU Strap = 125): 125-128 MHz

I tried to boot with 3/5 REG/DMI ratio (CPU Strap = 166) multiple times but no success.
The same CPU was checked in Intel DZ87KLT-75K board for 166 MHz BCLK OC.
Disabling intergated graphics core and using Palit 7300GT Sonic card won't help.

Memory OC was 2666 MHz 10-12-12-28 1T 1.85V - it's the same stable OC for used memory kit as it works on most Z77 boards before.

I was not able to boot at 2800 MHz memory clock on this board, even with 11-13-13-30 2T.


Performance measures in two modes - stock clocks (Turbo Boost enabled, 3700-3900 MHz depends on loading) and stable CPU OC on air cooling to 4500 MHz.
For comparison I used Intel Z87 reference board (DZ87KLT-75K) and one of the best Z77-based board ASUS Maximus V Extreme with i7-3770K CPU.
Memory runs with the same setting on all boards and both stock and OC modes - 2400 MHz 9-11-11-28 1T 1.80V 4x4Gb in Dual Channel mode.

Power consumption

I used UNI-T UT71E with power adapter to measure power consumption of the whole system "from the wall".

Z77+3770K stock mode settings: 3700-3900 MHz 1.000V CPU (Turbo Boost enabled), 1150 MHz iGPU
Z77+3770K OC mode settings: 4500 MHz 1.30V CPU, 1650 MHz 1.35V iGPU
Z87+4770K stock mode settings: 3700-3900 MHz 1.017V CPU (Turbo Boost enabled), 1250 MHz iGPU
Z87+4770K OC mode settings: 4500 MHz 1.15V CPU, 1800 MHz 1.35V iGPU

All Power-related BIOS settings and Windows power profile was set as "High performance".
There was some fluctuations all the time, I recorded peak power consumption in each measurement mode. It gives a rough estimate, but it's better than nothing.


After all I think Gryphon Z87 is a good small board for non-extreme users. It has all that they need.


The board works stable and without any issues. Voltages remains the same in idle and loaded (when CPU Load-line Calibration is set to Level 7 or 8).
Available voltage ranges, memory timings and other BIOS settings is enough for daily overclocking (air/water). Not checked any extreme OC with this board yet.
5 year warranty for TUF Series board.
Price isn't too big ($170) for the features it offers.


Big CPU heatsinks (like Thermalright Archon) can't be used with discrete graphics card and RAM modules with big heasinks at the same time.
If you mount CPU heatsink vertically - it will blocks first PCI Express slot.
If you mount CPU heatsink horizontally - it will blocks 3 of 4 RAM slots (but you still can use standard height modules).
It's very common restrictions of many mATX boards (and some ATX too), not only ASUS Gryphon Z87.

Memory performance is slightly lower than Intel reference board (DZ87KLT-75K).
I think it's because of some subtimings settings used different values by default and can be fixed in next BIOS versions.
On the other hand I stuck at 2400 MHz with Intel board no matter what timings and voltages.
In this case, lower memory performance of ASUS Gryphon Z87 at 2400 MHz is compensated by better (than Intel board) memory overclocking.

I was not able to boot at 166 MHz strap with the same CPU that works at this base clock on Intel board. May be it's just needs more time to tweak BIOS settings, I had only few days to test.
Also I can't boot at 2800+ RAM. May be it's matter of my CPUs IMC quality, need to check with more Z87 boards first before make final conclusion.
