Lots of FM2 boards pictured

Meaning these boards are tuned for Samsung and Hynix based ram?

The boards cannot be tuned for any "specific DRAM" if the manufacturer follows the official design guideline.
Naturally the manufacturer could add preset profiles containing optimal timings for a specific RAM component, however it is rarely done on other than the very highest-end motherboards (e.g ROG series).

Thats why there is a thing called A.M.P (AMD Memory Profiles), which is XMP compatible (as far as I know)

Some of the boards allow adjusting several parameters, which can have a positive effect on the DRAM signaling; DRAM reference & termination voltages, DRAM PWM frequency and UNB reference voltage.

Samsung based DRAM is better for Trinity as it seems to put less strain on the IMC (with identical configuration).

Thanks for the board info, good board it shall be. Probably the asus F2A85-M for the digi-vrm + good rep.
As for high ram speeds, my mushkin blackline 2133 clocked over 2400mhz, who makes them or how can I find out? My llano is going to get its 1866 g-skill ram back and the mushkins get to play with trinity.

Nice, looking forward to seeing prices etc of the trinity stuff, was impressed with llano.

Are there any boards designed with 4 + 3 phases for Trinity for some larger GPU overclocking? I think I am going to get a Trinity board with an H100 and some extra fans over the PWM and memory to see what these can really do

If the board is build with high quality components (+ the design is good), there is no need for 3-phase UNB VR.
More phases doesn´t necessarily indicate a higher quality VR. Generally it is just a indication that the board has some extra safety margins.
Extra safety margins indicate a higher quality product and higher overclocking potential, usually

GA-F2A75M-D3H was not on the list of boards at OCN (matx seems like mid range? )

What voltage would I need for a A10 5x00 on GA-UP4 for a 4.5GHz OC?

Hmm..

That fully depends on the VID of the base frequency PState (= leakage).

[initialised]

Obviously I can't post that here...

But it needs to be done today

Less than the "Turbo" voltage should be more than enough.
To check "Turbo" voltage, enable CPB (Turbo) from bios while CPU VDD (Vcore) is to Auto.
Save the changes and check what the current voltage is (== Turbo voltage).

I've lately been getting some very good OCs below the line on a F1A75-V EVO and I notice APU frequency on the F2A85 goes below the 90-300Mhz FM1 board range to 80Mhz. There are some very nice downclocks down there below 90Mhz, like 86Mhz x 24x = 2064Cpu x 1376ram(1600 divider) which really help power consumption as well as allowing a reasonable overclock without stressing the rest of the system, like 89Mhz x 47x = 4183Cpu x 1661Ram(1866 divider). AND I'd be interested to know what practical advantage DDR4 has to offer any time soon over a 2400 ram divider.

There is no point in underclocking with BCLK.
There are adjustable DRAM, CPU, NCLK and SCLK ratios if you like to underclock the system.
In optimal conditions the BCLK should never be adjusted.

The power management / efficiency on Trinity is nothing short of excellent so I see no point in further downclocking.
Besides the actual clock frequency has a very minor effect on the power consumption.
The voltage does.

[Yeroon]

The power requirements of Trinity are moderate.
More importantly the power consumption is quite linear when overclocked.
There is no rapid increase in power consumption caused by leakage on Trinity.

Four, or even three-phase CPU PWM will be absolutely fine for a APU with two CUs (4-cores) for all purposes.
However the integrated GPU makes nearly half of the total power consumption. Due the overclocking capabilities of the integrated GPU, I would not recommend anything less than 2-phase PWM for the UNB (Core & Graphics Northbridge). This is also seems to be the way most of the manufacturers are configuring their boards.

I do not recommend playing cheapskate when purchasing a board for Trinity, in case of overclocking is part of your plans.
Any high-end(ish) board from Asrock, Asus, Biostar, Gigabyte and MSI will be more than fine.

For maximum power efficiency (for HTPC etc), a board with a digital PWM is recommended.
Due the more advanced adjustments the effiency can be up to 10% higher.

The low-end boards use other shortcuts than just the PWM design.

+ A small hint, which should not be a surprise: A10 APU + overclock -> Make sure your DRAM is able to do atleast 2400MHz

ARRGH. Comparing features on Asus website,
M-LE loses 1 cpu power phase (down to 3 + 2, digital) compared to M, both un heatsinked,
Some extra features like mem-ok and Remote Go! are also not on the le.
No crossfire X on the LE, not enough case room anyways.

But I don't need any of the extra features the M or Pro give. Heck, the a75 chipset is more then fine for me, but only a85x available (from asus)

Is the Asus LE board really low end enough to qualify as low end? Again, no more then a modded LC closed loop setup for cooling. I can add a vrm waterblock and a ram one (maybe) if needed.

The price difference between the models shouldn´t be that huge (other than percentual).
The best FM1 board from Asus was around 100 USD or so?

There will be A55 & A75 based boards from Asus too, so there might be some interesting models available.
Also Asrock F2Ax5-M Pro4 board should not be overlooked.

It has a digital 4+2 phase digital VRM (with a heatsink on it) and there is an external Pll too

AMD will stick w/ the FM2 socket for a longer time

Sapphire got a mini-itx one in the works:

It is supposed to go to FM2+ in another year, much the same way AM3 went to AM3+ for the new processor generation. FM2+ will combine the current "low end" segment with Trinity's successor and the "high end" successor to Piledriver. This was shown in an AMD slide quite a while ago.

Kaveri is Socket FM3.

[FlanK3r]

but Kaveri will be maybe 4Q 2013 or later I think, right?

[cezar]

AMD is committing to one more generation beyond Trinity for the FM2 platform.

There is no point in releasing Kaveri for Socket FM2, unless of course the frame buffer (VRAM) is integrated in the die.
There is simply not enought memory bandwidth available with the dual 64-bit memory controller and DDR3.

The only way to have faster GPUs in APUs is either making the IMC 3 or 4-channel or adding an IMC for external GDDR5 (similar solution to sideport).
