Most of the boards in today’s test reached 4.6 GHz, except for Asus’ A88X-Pro at a similar 4.55 GHz.

Maximum reference clock could be important to memory overclockers who’ve already exceeded the Kaveri architecture's top 24x DRAM multiplier, or to anyone who somehow ends up with a multiplier-locked APU. Asus, Gigabyte, and MSI are closely matched in this capability.

Asus tops our memory overclocking tests even after also topping our stock-speed memory bandwidth tests. Performance and stability are definitely a killer combo.

MSI's firmware automatically attempted to tighten memory timings when we reduced memory clock rate, even though our frequency reductions were an attempt to recover from failed boots. The A88X-G45 Gaming might have been able to reach a slightly higher DRAM clock with more manual timing adjustments. On the other hand, our most recent tests show that data rates beyond DDR3-2133 provide no performance benefit to recent platforms.

- Which A88X Motherboard Is Best?
yes. but at a lower price range probably. first, a10 7850k itself has to come down in price by $40-50 outside microcenter.

Even beyond price, ATX seems pointless with a Kaveri APU. Myself, I'm waiting for the A8-7600 to build a very small (< 3 liters) ITX HTPC running the APU in 45W mode. Although I'm very excited about doing that build, I can't see any use case that makes sense for a Kaveri APU in an ATX form factor. Perhaps the A88x chipset has some feature benefit for building something using the 750 or 760k CPU in a budget build. But the only build I would even think about using a Kaveri APU in would be a mini-ITX PC/HTPC or laptop.
Beyond that, I would love to see Lian-Li come out with a tiny case like the PC-Q02, PC-Q09 or PC-Q12, but with the design for a single 120mm CLC and a 300W SFX PSU to allow a decent overclock on a 7850k APU with the smallest form factor possible (i.e. < 8 liters). That type of build might get me jazzed up for the 7850k.

yeah. but uatx or mini itx doesn't give easy access to that many sata or usb ports, usually.
imo, the atx boards make for great media and casual gaming builds with 8 sata ports (at that price).
in gigabyte's case, dual usb 3.0 headers open up more inputs for external storage.
the typical apu buyer goes for cheaper uatx boards, followed by full or slightly narrower atx motherboards.
yes. but at a lower price range probably. first, a10 7850k itself has to come down in price by $40-50 outside microcenter.

It is not pointless atx has more usb, pcie.and sata ports available. Atx boards are stronger and have better heat dissipation. I have seen many matx boards crack from big air coolers hanging inside of the case. Your preference is just that your preference.
Ok, so I'm just cracking up at the thought of a Kaveri APU build with 8 drives, dual graphics, and a big air cooler hanging off it - maybe it's just me, but it seems counter to the whole concept of the APU.
I mean, the ASRock FM2A88X-ITX board is quite capable. 6 SATA 6.0Gb/s, 1 mPCIE/mSATA, 32GB RAM, total of 4 USB 3.0 and 8 USB 2.0.
But you're right, that is my preference/opinion....
I usually go for ASRock products, but this particular model is hard to get behind. They pull the eSATA, half the SATA cables, and still keep limiting the 4-pin fan headers. PLEASE, Tom's, can you tell these manufacturers that all fan headers should be PWM?
And I don't get the PCI connectors either. Sure, someone may still have one legacy PCI device, but two? Meanwhile the PCIe x1 slots almost always bracket the top x16 slot so the lower one is usually blocked off. Here's an idea: put one of the old PCI slots right below the top x16 slot. My guess is the people who still have PCI cards are also the ones who don't have dual-slot GPUs, and vice versa. That way people who don't use the PCI slot never have to worry about covering up something they may actually need in the future.

Glad i could give you a laugh, I myself like a good matx board when the build warrants the use of one. I know some big UATX fans also. My asrock extreme 6 has 3 pcie 16 and 2 x1 slots. 7 x SATA3, 1 x eSATA, 6 x USB 3.0 (2 Front, 4 Rear), 8 x USB 2.0. supports dual graphics and 3 way cross fire.

Don't get me wrong - I've got no problem with ATX or uATX form factors. I have a uATX under my desk as my 2nd office PC (a laptop for work & uATX desktop for gaming, ripping or whatever when I need a break). It's still running an AMD Phenom II X4 965 that I paid $75 for plus a new R9 280x. AMD just hasn't given a good enough incentive to upgrade from that point, and I'm frankly considering a switch-over to an I5 for that system. I'm reluctant to upgrade in the AM3+ path, and the FM2 platform just hasn't provided anything better than what I have now.
I'm also pretty excited about Kaveri in general, but for the ITX form factor. Felix666 above has a pretty good use case for Kaveri on ATX. An I3 with a fanless R7-250 would be faster but ~$40 more expensive (assuming you would still need the same heat sink). Anyway - didn't mean to ruffle any feathers....
