The AM1 Kabini Motherboard Preview: Analyzing the Hardware
by Ian Cutress on April 19, 2014 2:00 PM ESTBiostar AM1MHP
Biostar’s other option for AM1 is a proper microATX motherboard that carries over many of the traits from the AM1ML. The DRAM slots are still at right angles to normal motherboard operation, and the 4-pin CPU power connector is next to the rear IO which will hinder cable management. The audio codec is also the same ALC662 codec we normally see on the ultra-low-end motherboards and laptops, but the network controller is upgraded to one that can support a gigabit connection.
The two SATA ports on the right hand side are both pointing in the same direction, suggesting that when using locking SATA cables the one on the left as seen might be hard to remove if the right port is populated. The BIOS chip is at least removable, should the unthinkable happen. With regards the memory slots, notice how (like the AM1ML) they are placed next to an empty space in the rear IO panel. Depending on the rear dust shield that comes with the motherboard, this server-type arrangement is usually performed to aid airflow from right to left across the components.
While the $35 GIGABYTE seems to have a preferential orientation and hardware allocation, the Biostar AM1MHP does have a PCI port that can be used to exploit older expansion cards.
The rear of the motherboard is identical to that of the GIGABYTE AM1M-S2H, except the HDMI port is now upside down. We still have both the PS/2 ports, the VGA port, two USB 3.0 ports, two USB 2.0 ports, a gigabit Ethernet port and the audio jacks.

Sorry for the error on my part, I got the 5150 and 5350 mixed up :-(As per your original post, where did you see that nice 5150 OC? With an ASUS board should the same type OC be possible with the 5350?
Thanks!

At techpowerup. http://www.techpowerup.com/forums/threads/amd-kabi...But overclocking on this platform is still a big question mark. At Phoronix for example they also tried to overclock ALL the four processors available on the same motherboard and in ALL cases they had stability problems over 105MHz bus speed. So more time is needed to have a definite idea about the overclocking potential on this platform.
As for 5350 I don't know what frequency it can reach. 2100MHz should be easy I guess with just a multiplier change from 20.5 to 21, gut it does make you wonder why AMD didn't gave 5350 the 21 multiplier in the first place.

The problem with the Kabini platform is that it makes too many sacrifices for too little gain. You can buy an Intel G3220 and an MSI H81M mobo for around $100 and while it may consume 10-15W (on paper) more power it will give you about twice the CPU power.As for real world power consumption, I recently build a G3220 system and even when under 100% max CPU and GPU compute using Hash Suite it never exceeded 60W. Under most everyday loads it used about 40W. Given these numbers it is difficult to make a case for the Kabini platform.

I was contemplating similarly. I also wonder with the increased compute power if getting to idle quicker doesn't also attack any power savings.yannigr - Monday, April 21, 2014 - link
You gone from $60 to $100. This isn't "too little gain". Also you forget that the Kabini platform does have better graphics. Much better graphics. And I am not talking (only) about performance, but compatibility also.So, if you need cpu power and you have $100 you can go for Intel. But if you want a better balanced solution in gpu-cpu performance and keep $30-$40 in your pocket, Kabinis are the best option.

I agree.Carleh - Tuesday, April 22, 2014 - link
Does the G3220 support hardware accelerated video decoding?It does support quicksync, but I'm not sure if quicksync can be used for hw accelerated video playback in all applications (flash includeed).
I know the G3220 is powerful enough to do all the decoding in software, but I see no point in using software video decoding in 2014.

I remember from the slides that were presented by AMD at launch, that ECC RAM (unbuffered) was supported. Why isn't there a single motherboard that supports it? In it's current form, Kabini is not an option for building a cheap ZFS storage box.Death666Angel - Sunday, April 20, 2014 - link
Why does the motherboard need to support ECC RAM? I'm pretty sure they are physically identical to normal RAM and since the SoC handles all memory (as with most modern CPUs/APUs), the motherboard has no say in it.Chicken76 - Sunday, April 20, 2014 - link
I'm not sure, but if you're not using error correction on a DIMM, do you still need all the traces? They might not have them all in place, to keep costs to a minimum.Besides, you still need BIOS support for ECC.
