DQ77KB Thin Mini-ITX - Page 2

It's actually cheaper here http://www.shopblt.com/item/intel-i7-3770t-tray-processor-3.70ghz/intel_cm8063701212200s.html

That's where I ordered mine, it's supposed to ship to me in the next week or so. Out of curiosity I checked out that sabrepc.com link, and their checkout page was insecure (chrome told me), they charged tax to ship to NY, even though they are located in CA, and their shipping was pretty expensive. For ground to NY it would have costed me $345

ilovejedd: did that PSU that you linked actually work with the board, or have you received it yet?

Mini-Box also has an mPCIe to ExressCard adapter that is designed to work with the DN2800MT; it looks like the I/O shields for the DQ77KB and DH61AG also have the punchout for this adapter over the HDMI and DP ports: http://www.mini-box.com/ExpressCardAdapter Of course, this requires the full-height ATX I/O shield.

You could use an Intel INT-6230 mPCIe WiFi+BT card, wireless mouse+kb combo, and eSATA external drive if preferred. Probably not worth the cost, just sayin'.

It'll work, assuming Intel didn't do something really weird and use a different connector than the DH61AG; they should both need a 7.4 x 5.1 x0.6 x 12mm barrel connector

Sure, I like those Apple looking KB and have a nice Microsoft laser mouse. Of course the external USB HDD for backup is a few years old. That PCIe adapter is a nice find. I was wondering what that cut out is for.

I was wondering what the cutouts were for too. From the looks of the http://www.mini-box.com/ExpressCardAdapter linked above, it wouldn't work on the DQ77KB. The mini-PCIe connector is the wrong orientation (it runs parallel to the PCIe connector on the DQ77KB).

I want you to be right about this, but this is why I asked:





I actually tried to ask Intel about this, but the guy I spoke with was worse than useless and sent me to a HQL for ATX power supplies.

So for those of you who are actually running a DQ77KB today, what power supply/adapter are you using with it?

I bought a STD-19084 160W 19V adapter from mitxpc. This web store is actually located in the Bay Area and I just drove to their office. They carry many items for ITX setups such as special I/O plate for DN2800MT.

I also tried it with a Kensington 120W Model 33197 travel charger with a N19 tip for Dell laptop. This setup runs at 20V which should be ok for +5%. But this adapter consumes about 6W with the DH61AG computer on S3 standby, which is poor. Should be around 1.5W. A real Dell adapter should be better.

There is an internal 2 pin power jack on the MB and I got a Lenovo fanless 19V switching power supply FRU: 71Y8204 to try. Just need to attach the correct 2 pin output connector.

I have a few different ones for Dell and HP laptops, stuff I came across at work. Some lower power ones, and a huge 200w one.

Got any part numbers?

Dell (Delta) DA210PE1 210W

Dell (Delta) J211H 230W came w/ my Alienware M17R3

Dell J62H3 90W This powers up my DQ77KB w/ an i3-2120T, mSATA SSD, 16GB ram, 140MM fan, and 3 x 3.5" sata HD's (4th one causes it to power down at boot when HD's spool up).edit: I just realized the ancient seagate ST3250823A 250GB drives I was using to test use like 2x the power of my samsung 2TB F4's... so I should be fine with this adapter when I swap out the drives. These seagates use like 34 watts each at startup http://www.seagate.com/support/disc/manuals/ata/cuda_72008_pm.pdf

HP HSTNN-LA25 120W came w/ my HP Envy 15 3rd gen

Are the Dell PSUs 19V or 20V?f

According to that Amazon seller, that PSU has a plug that would fit the DH61AG, but not the DQ77KB (7.4mm outer/5.0mm inner). Assuming Intel's documentation is accurate and the seller is accurate, of course. It looks like other generic PSU replacements for this are 19.5V.



Yeesh. Thanks for the part numbers, tho. It's a good start.

All the ones I listed above are 19.5V

Those also look like they've got 7.4mm/5.0mm plugs. Does this mean that the Intel doc is wrong?

There are two power connectors used:
DH61AG, 7.4mm/5.1mm, 19V
DQ77KB/DN2800MT, 5.5mm/2.5mm, 8V-19V

I'm not sure about the Intel specs. But I have both those boards, and all the power bricks I listed above, and they all work with one another.

About the external power supply, I think the DC external connector is the same as for the DH61AG because this is the next-in-line upgrade for Intel's only thin mini-ITX. The 2.5 ID/ 5.5 OD specs for the plug might be a misprint/mistake by Intel; I have the same specs in some notes I got from pre-introduction gossip but the best source for accurate information from Intel is any document that does not have pictures of people in it (i.e, technical documents). I have not called Intel Help on this because when I called to notice that some of the spec sheets they had online listed the DQ77KB as using 240-pin DDR3 when it is obvious the board uses 204-pin SODIMM, I spent 30 minutes gettings nods and thank you's but none of the incorrect documents have been changed. For the right plug, check with Mini-box.com or atechfrabrication.com.

I noticed some problems I had with what I thought was a dream thin-mini-ITX, the DQ77KB in an earlier message in this thread. Here are some more notes:

1. The audio codec is ALC-892. The signal to noise for this codec is about 90dB for output. That's not great, and wouldn't replace very many soundcard options. So if you want great sound quality and want to use a DQ77KB, think about using a soundcard, and there goes the PCI-e 3.0 slot (remember, it is just four lanes of 3.0). The DH77DF board from Intel has the 898 codec and bring the signal to noise up to 110dB--that's a real challenge to most available sound cards. The DH77DF is a mini-ITX but stands about an inch higher than the DQ77KB.

2. The only third-generation i7 processor you can use with the DQ77KB, according to Intel, is the 3770s. You can't use the k (unlocked) or the t (low-power) versions. This means you can't change the CPU or memory clock with a DQ77KB (except possibly reducing the native speed of the processor in the BIOS to control temperature).

3. The paradox is: why have 3rd generation processors that are supposed to save energy but can't use low-voltage memory? The solution is: use low voltage-rated memory (DDR3U- DDR3 L1.25- 1.35V) but use the higher (1.5) voltage required for the 3rd generation processors for over-clocking the memory. The problem is, you can't change the clocks on the XXXXs processors that are required for the DQ77KB.

My question to the readers is: can you use the 3770K in the DQ77KB, not at 77W TDP but 65W TDP by underclocking it? Maybe Intel does not list the 3770K as compatible with the DQ77KB because if you let it fly at 77W it would destroy the board, but in more careful hands... Let me know if anyone has tried it and thanks.

That only maters if you're using the analog outputs, which being only stereo, are not going to be much use to people here. I'd suspect most here would be using HDMI for audio.

Not sure why that matters, who's going to overclock a 3770S in one of these? I mean the 3770S is way overkill for this sort of system to begin with (speaking as someone who just built one of these with a 3770S).

Agreed.
There's a second mPCIe slot above the HDMI and DP ports.
I think you're right. There's no way that size power connector would handle enough juice for the 65/77w CPUs.

That doesn't make much sense, especially when you consider that Intel is pushing Thin Mini-ITX for AIO systems, where thermal management is a big concern. They should definitely be able to use the T-series CPUs. We're waiting on an ETA for the i5-3470T from the distributor. As soon as we get one in, I'll get this tested.

True, but that's also the mSATA slot.

I'll be trying the i7-3770T on this board, as soon as my order ships. I see no reason why it shouldn't work - even if it hasn't been officially tested/listed in Intel's specs. It's just a lower clocked, lower voltage binned 3770/s. If it doesn't work, then I'll replace the 2500K in my desktop.

I think they added the 65W CPU support late. Then the 8V-19V @ 8A power connector would not support 65W CPU option. So they changed to the 19V only connector but the smaller connector got left in technical literature.

which cases have you used successfully? The antec 110 Vesa fits the board but also includes a power supply (which is redundant if you get the compatible power brick)

I used 2 different Lian Li case in my little projects to take advantage of the thin-itx form factor:

My Lian Li PCQ16
My Lian Li PCQ05

edit: Also, my i7-3770T shipped today. So I'll know shortly if it works in this board or not.

i7-3700T plus DQ77KB is a lot of power for a media server. This is also your desktop machine?
