The BIOS is a standard American Megatrends BIOS with all the normal bells and whistles. |
| Basic boot settings and some advanced CPU configuration but not overclocking under advanced settings, overclocking has its own header. |
 |
 |
Overclocking is under the Power user overclock settings. Under the overclock settings you can change just about every value under the sun including overclocking your graphics card, down coring your processor or setting the individual timings on your ram should your ram support it. |
While using the BIOS to overclock is certainly the power users way of squeezing more power out it is not by any means safe, you can damage or destroy your board and processor by monkeying around with settings you don’t understand. The HA12-LF has an overclocking utility which makes it very easy to overclock and while not completely safe its not nearly as dangerous as using the BIOS, if you are unfamiliar with what these values do but you want to overclock I would strongly recommend using the Hummer overclock utility. ( NOTE: Due to unforeseen circumstances the overclock utility was not available at press time for this board. )
I benchmarked the network performance of the Realtek RTL 8111DL chipset to rate its read write transfer speed over a gigabit network.
LAN speed test
 |
The network test showed fairly unsurprising results for a gigabit network card. Most gigabit network cards rarely put up a sustained 1000Mbps like they are supposed to most on-board NIC’s in the desktop market put out about 750Mbps which is what we saw with the Realtek RTL 8111DL. This test transferred a 100mb file to a server locally (within 10ft ) over Gigabit Ethernet. |
HDTach – SATA III test
| This test showed some surprising results, I originally ran this test using the very common Marvell 88SE9123 SATA controller which is used in a large number of SATA III devices including the Asus P7P55D Premium motherboard we reviewed this time last year. The Marvel Controller is in blue where the AMD SB850 chipset is in red. Notice how much more stable the read/write rates are, the average read time is also 3MB faster than the marvel controller.
Both tests were done on the same Seagate Barracuda XT drive |
 |
AES Encryption
 |
This benchmark takes advantage of the pathways between the CPU and RAM as both are heavily utilized. The benchmark itself is a test of the systems ability to handle cryptography. Overall this build did very well for only being a quad core processor. |
Zlib – Zip Archiving – Compression/ Decompression.
| This benchmark measures combined CPU and memory performance through the public ZLib compression library. Similar to the AES encryption this system did very well for only having access to 4 CPU cores. |
 |
I avoided using benchmarks that rely heavily on GPU or other subsystems and instead focused on benchmarks that showed the actual performance of the main board, I feel this provides the most accurate results of what Jetway’s HA12-LF can do.

I bought this MOBO back in march for a custom build and have had nothing but issues with it. I originally installed a dual-boot windows setup and would get freezing, black screens and BSOD’s randomly. This is with all official drivers and compatible hardware, recommended ram voltages and no over-clocking at all. I decided to RMA it a month later and got nowhere. I have changed out the CPU, ram, and even the HD and PSU with the same results. Now I can’t even get Jetway on the phone anymore to pursue further recourse. Steer clear!!!
