ASUS M5A78L-M / USB 3.0

Dual-Channel DDR3 2000 (O.C.) support

The motherboard supports DDR3 memory that features data transfer rates of 2000 (O.C.) / 1866 (O.C.) / 1800 (O.C.) / 1600 (O.C.) / 1333 / 1066MHz to meet the higher bandwidth requirements of the latest 3D graphics, multimedia, and Internet applications. The dual-channel DDR3 architecture enlarges the bandwidth of your system memory to boost system performance.

ErP Ready

The motherboard is European Union's Energy-related Products (ErP) ready, and ErP requires products to meet certain energy efficiency requirements in regards to energy consumption. This is in line with ASUS vision of creating environment-friendly and energy-efficient products through product design and innovation to reduce carbon footprint of the product and thus mitigate its environmental impact.

CrashFree BIOS 3

Simply Restore Corrupted BIOS Data From USB Flash Disk
The ASUS CrashFree BIOS 3 allows users to restore corrupted BIOS data from a USB flash disk containing the BIOS file. This utility saves users the cost and hassle of buying a replacement BIOS chip.

Eight-Channel High Definition Audio

The onboard 8-channel HD audio (High Definition Audio, previously codenamed Azalia) CODEC enables high-quality 192KHz/24-bit audio output and jack-detect feature that automatically detects and identifies what types of peripherals are plugged into the audio I/O jacks and notifies users of inappropriate connection, which means there will be no more confusion of Line-in, Line-out, and Mic jacks.

1. Real-time over voltage detection.
2. Active protection against potential damage to your motherboards and systems.

CPU Parameter Recall (C.P.R.)

The BIOS C.P.R. feature automatically restores the CPU default settings when the system hangs due to overclocking failure. C.P.R. eliminates the need to open the system chassis and clear the RTC data. Simply shut down and reboot the system, and the BIOS automatically restores the CPU parameters to their default settings.

4 out of 5 eggsIt's a motherboard

Pros: It's a motherboard, that's all there is to it. I upgraded to this mostly for the 4 Memory slots. I've had no problems with this board so far.

Cons: None so far.

2 out of 5 eggsGreat on Paper. Reality is a bit Different

Pros: Inexpensive. OK features & layout for an entry system. On board USB3 chip (albeit no internal header).

Cons: Unstable.

Other Thoughts: I had it running with 4-core FX chip & 32GB of quality memory. Unfortunately when loaded with Win 7 every so often it will BSOD or just freeze for no apparent reason. Similar issues with Debian based Linux distro I tested.

2 out of 5 eggsNot recommended

Pros: USB 3.0, gigabit LAN, On-board graphics

Detected Corsair 4GB RAM stick right away

Great as dirt cheap build, I don't live in a trailer park but with this board might as well...

Cons: 1. Cheap
2. What happened to the I/O Shields? They are all junk from ASUS, don't fit right at all and yes I'm installing the right way

3.. BIOS settings are the worst I've seen
4. Only 1 Fan Header besides CPU Fan.

5. It varies the voltage to the processor to save energy, I haven't found a way to turn this off from the BIOS
6. No SATA 6GB/s!!

Other Thoughts: There no way I would pay for this board, I got it for free as part of a bundle from another store, it is fine as a cheap server, my old server was a VPR Matrix computer Pentium 4 from 2002 with 1.5GB of old DDR2 RAM, so upgrading to this board from that is a HUGE leap for me and a great deal (using 8core AMD FX 8320). Overall I'm happy but I don't trust this board at all, I'm going to be getting the cheapest RAM I can to put in it and luckily it has on-board graphics so it can't destroy a discrete graphics card.

4 out of 5 eggsNice board

Pros: Inexpensive. USB 3 ports, PCI-E X 1 slot not blocked by double slot display adapters. 4 DIMM Slots.

Cons: Only two fan connectors.

Other Thoughts: Build with FX-6300 processor was straightforward with no issues. Recommended.

3 out of 5 eggsDisappointing

Pros: Simple, cheap, and works. Mostly reliable.

Cons: Is temperamental, not the best BIOS, terrible manual, cheap.

Other Thoughts: Bought this board as my first build on july of 2014, needed something cheap to meet budget. Was finicky to get everything set up to work right. Had a major failure with the networking, required a complete system reinstall to fix. Not a board to OC or take chances with, I would recommend going with a more expensive board. This product is definitely just a bad model from ASUS. Works fine when it does work, have tested all other components and it seems to just be a not-so capable item. If youre building a cheap entertainment pc, this would work fine. (AMD FX6300, MSI R7 265, ASUS LAN card, crucial sport RAM, Seagate Baracuda HDD.)

2 out of 5 eggsGreat Features...Unreliable

Pros: USB 3.0 Support
4 DDR3 Memory Slots
Good ASUS Customer Service

Cons: This board worked for 6 months before it failed. I sent in to ASUS for repair and a month later it failed again.
This motherboard is unreliable

Other Thoughts: I basically lost about $65 for a motherboard and not a cheaply made one either. I'm very disappointed at ASUS for this and they are a good company though.

2 out of 5 eggsFalse statement about CPU wattage support and memory ECC support.

Pros: boot usb related device without problem,
GA-78LMT-USB3 is picky about this

Cons: 1.
it statement as it support CPU up to 140w, so I put a FX-8350 on it,
yes it do, somehow, bootable,
but if you put CPU under load, soon you will see it throttling,
this issue seems base on it have no heatsink over VRM mosfet,
which trigger it's overheat protection.

then I bought GA-78LMT-USB3 which have no such issue.

it states about it have ECC support on memory,
I have to use ECC because I use ZFS,
which is also true, somehow,
while I explore around ECC option on BIOS,
it's kind confused because there is a User option,
but all you can do is Enabled/Disabled,
yea, ECC support

so I tried to contact ASUS support about this two issue,
then they took two day with a useless replay,

this board is design for general home usage, not for workstation and server,
it doesn't support ECC, we suggest you use non-ECC memory,
and also using Windows OS as well

really nice customer support, so I returned it.

2 out of 5 eggsWas perfect

Pros: Worked great along with EVGA GeForce GT 640 2GB 128-Bit DDR3 PCI Express 3.0, 4x 2gb Kingston memory, 1tb Seagate Barracuda hard drive, 700wat power supply and a quad core cpu. Was the perfect setup

Cons: had about six months then it crashed and said bios error so i slid in cd that came with and it redone the bios and worked great for a while longer till 2days ago then blacked out after another bios error now it is brain dead 3days and still not working.

Other Thoughts: Would like to have it replaced but seems like the wait through this site takes to long. I still have a pc that is 15 years old and might be slow but mother board still works and havn,t had as much problems with it as this new mother board.

4 out of 5 eggsJust what I needed

Pros: AM3+ compatability meant I could re-use my Phenom II X4 CPU.
DDR3 support & 4 RAM slots meant I could re-use my GSKILL RipJaw 16GB kit.
6 SATA connectors
onboard HDMI

Cons: Only SATA II
no USB 3.0 header/19 pin connector
only 2 fan connectors

Other Thoughts: Not docking an egg for the lack of SATA III or USB 3.0 header; this was my fault for not reading good enough. I am docking an egg for only having 2 fan connectors. Supports lots of RAM. Easy build; booted right up & has been stable for over 2 weeks. Basically made a nice replacement PC from this & spare parts from my dead HP Pavillion P6540f.

AMD Phenom II X4 CPU
16GB GSkill RAM kit @ PC3-10666
Toshiba 256 GB SSD for OS/applications
Seagate 500 GB HDD for storage
1TB 3.0 external drive for backups
Rosewill Galaxy-02 mid tower
Rosewill ARC 750W power supply
LG DVD DL drive

Future plans for PCI-E video card & Blu Ray drive/burner.

1 out of 5 eggsPile of cr*P

Pros: Looks nice,cheap and has 4 ram slots.

Cons: Does not POST at all.After buying this board to replace my hp default board which the sata controller on it died. This board was a complete waste .. bought it on the 16th and spent about 4 days trying to get it to post. Nothing at all there is no display at all, even with a gpu the mobo just causes fans to spin at max rpm and that is all. Highly disappointed I sent it back to newegg for a replacement but i'm angry about all the waiting. The wait time has been about half the month now in total. Just very sad i thought new egg was a great place to buy from.

Other Thoughts: Dont buy it it's cheap and looks like a good deal but 20 $ more can g a get you a better mobo which you wont have to rma.
