Did you ever entertain the idea of upgrading the cpu? I see that i5-3470T would work with this mobo with better performance and the same power consumption/temperature. (35W and 65C) The mobo supports turbo boost (which the stock i3 lacks) and hyper threading (again none on the stock cpu).
I think with a reliable power supply, one can use an i7-3770T for quad core performance at 45W (69.8C). ------------------------------------------------------------------------------------- I opened up my unit and looked into the audio board. I found some internal pictures of the autonomic mms-5a to compare. I have some good news! -MB100 uses one of the usb2.0 headers to grab its audio therefore it uses asynchronous connection. (mms-5a grab its audio from the asrock mobo's analog audio outputs with its inferior dacs) -usb audio is up/oversampled in sw (still). -coax/optical output are converts from the usb2.0 header. (MB100 has a built in usb to spdif) -Asrock mobo uses decent capacitors so the voltage regulation should be fairly clean. A molex from the mobo provides 12V.5V,3.3V to HDD/SSD and the Mcintosh audio board. -Mcintosh audio board has an isolated dc to dc converter for the op amp section after the dac. Any noise on the mobo and the rest of the unit is blocked. -analog dc power on the ess chip is common choked using LC components. |

I think I am going to do the CPU upgrade. It's simple to do, just can't decide whether to go with an i7 or i5. While at it, I will swap the stock heatsink/fan with a better one as well.

Did you do the upgrade? I'm slowly starting to understand the benefits of the MB100.

MB100 upgrade downgrade Blu screen
Hi to all.
My MB100 is driving me crazy, I have yet no permission for a new thread and I really no idea where to start from (also my english is not the best as I'm writing you from Italy). Two years ago I have had some problems solved by autonomic remotely, then I was not able to use my MB100 for numbers of personal reason. Last week I was finally able to switch it on again. No way to connect it, also if it was set for fixed IP 192.168.1.113 (and I could reach the web interface) on my TV it was displayed 10.0.0.8 no server connected. Tried to upgrade. MB100 remained in "processing please wait"... unable to connect anymore I tried with bios. First I upgraded to 1.60. Disaster, Blu screen check you hard drive... etc etc. As I am out of guarantee now, I spend the unit, installed the 30gb SSD connected to my pc and checked for virus and everything else. Nothing changed. Then I downgraded the bios to 1.30... still nothing. When I tun it on the ASRock page appears with the options F2 F6 or F11. I can access MoB menu but as I exit, few moments and the blu screen appears.... I also upgraded to Crucial 16gb ram but naturally this couldn't help. Any of you can give me an help? |

Next on my list is to feed the dac section with a separate 5V rail from the hdplex 200w linear supply. The original design gets its power from the 5V sata output of the motherboard (which goes thru dc to dc conversions from the 19V mains). |

Send out your unit for OS restore first. Soon as you get it back, swap the drives(clone them onto better ssds) and keep the originals as your recovery drives for future. |

I have the i7-3770T. I ordered a noctua nh-l9i cooler and corsair dual ssd mounting bracket.
I will replace the stock cpu and cooler next week and move both ssds to the left side of the case. A little better breathing room for the motherboard and a much better cooler. |

I installed the i7-3770T along with the Noctua NH-L9i cooler (with the low noise adapter). It works really well. I can't tell if it is any faster but it makes a lot less noise.
The only noise I hear is the cabin noise due to the negative pressure. There are a couple of intake inlets on the bottom but they aren't big enough to suck in enough fresh cold air therefore the negative pressure. Installing a couple of small 40mm Noctua fans before these bottom inlets can help reduce the negative pressure and reduce noise. The ASRock H61 itx motherboard has another case fan output which can be used for this. Sound dampening on the top cover is also a good idea. I also replaced the stock SSD and HDD with a 128GB and a 1TB Samsung 950 Pro drives. I used a Corsair dual SSD bracket to install these (stacked) on the right front side where the original 3.5" HDD was. I replaced the stock SATA cables with Cablemod ModMesh cables. A red one for the 1TB media drive and a blue one (McIntosh blue) for the OS/Sw drive. These changes might help slightly with the air circulation however mostly for cosmetic reasons (better cable managed). Lastly I swapped the stock 2GB ram with 2x8GB Kingston RAM just because. For the CPU/Cooler upgrade: You need to remove the stock cooler and CPU. You need to apply thermal compound on the new CPU. You need to remove the motherboard to secure the new Noctua Cooler to the back of the board then install the board back to the case. All together, I got all this done well under half an hour but I have build many computers before. If you have never done this before, it is ok if it takes you a couple of hours. I would say the difficulty level is 6/10. |
