I will be sure to let you know if the HDD lights work or not. If they don't it really doesn't matter to me as I never use them in the first place. I never plug them into the motherboard on my computers I build because the LED's annoy me.

Thanks

Ok I played around with the GT7725 tonight and decided to use a regular SATA 7200 rpm mechanical drive on it with Windows 8 and I must say this thing destroys the T5735 in just about every way possible. It is fast and responsive just like my desktop and played every 1080p files I threw at it. The on board HD 3200 video card did extremely well when I streamed games through steam on my desktop to it and it was just like I was playing them on my desktop with no noticeable lag or artifacts. The HDD LED did in fact work on the front of the thin client just fine but the adapter itself does not have a LED on it. I am pretty excited to get my SSD in and finish thing this up. It is going to be the ultimate set top media/game box imaginable. I tried to get a picture of the HDD LED working. Excuse the ugly rug in my office.

I'm guessing it's fast 'cause it has a 2.4 GHz or faster CPU
plus, it's the Ultra model# CPU.
Your T5735 just has a 1.8GHz right?

My T5730 plays 1080p without troubles too.

How much RAM is in the GT7725 now?
How much can it control?

The fact you have a full x16 PCIe and the two working RAM slots is cool.
Had I known about the GT7725 back when, I'd have gotten one of those.

You may have given me a clue, as to my IDE to SATA adapter stopping the drive LED lighting.
Your adapter doesn't have a LED for drive activity.
Maybe mine having one is competing with the built-in one of the TC.
I'll remove it, and see what happens.
(The LED and the resistor in series with it.)

Right now I only have the two 1gig sticks of ram it came with. I am going to take the 2gig stick out of my T5735 and put it with a 1 gig stick to make 3 until I can get another 2gig stick. I am sure the T5735 would play HD video just fine with a pci-e video card but this one does it with the on board video.

That's amazing, about the video card, 'cause it didn't get good benchmark results, according to this other site...
http://www.videocardbenchmark.net/gpu.p ... on+HD+3200

I guess it shows, not much power is needed graphic-card wise, to play 1080p
And may count on the CPU more.

What speed is the GT7725

T5735 · Post by **T5735** » Tue Sep 16, 2014 8:26 pm

It has a ZM-84 CPU which is 2.3ghz.
http://www.cpu-world.com/CPUs/K8/AMD-Tu ... M23GG.html
The on board video seems to work really well for what it is. I was playing some brand new games that are less than a year old on high with it. Granted my desktop was doing all of the work and it has a 2gb Nvidia 560ti in it and the thin client was just streaming what it was doing but still it is pretty impressive.

See..?
My point... If you put in at least a TL-66 @ 2.3GHz and a PCIe x16 working as x1 in the T5735,
it should work as well as your new toy.

I'm sure - if you tried to play a 3D game on the GT7725 with the stock graphics, at full 3D quality
it would have troubles. But the fact you can use a full x16 PCIe in it, is very cool

It looks like my model number is NG814AA#ABA. You could probably buy just the board somewhere but I don't think you will be able to find one as cheap as buying the entire thing with expansion module off ebay for $49+shipping.

I actually got the stock PSU in today but did not look at the wattage. It has a massive brick on it though. It is probably 4 times the size of the stock one for the T5730.

2 and 1/2 times larger.
The T5730 stock PSU is 50 watts (around 4 amps)

GT7725 around 9.5 amps

My new T5730 PSU = 16 Amps

192 watt
But yet, it's not that huge a brick.
7" x 3" x 1 and 3/4"

I wonder what the fastest CPU is, it can handle.

Or what's the fastest made in that series ultra dual-core.

I am pretty sure it is the ZM-88 2.5ghz but I have not been able to actually find one for sale online. The fastest one I can find is the ZM-87.

Have you seen this about the PCIe slot on that GT7725

They claim you can't put in just any x16 PCIe card.

http://h30434.www3.hp.com/t5/Desktop-Ha ... -p/4095850

Someone tried, and the system didn't work with any other than the one HP says to use.

So you may not want to invest in a new CPU just yet

Oops

I actually tried to put a HD 3450 in it but it would not fit as the heat sink was to big. I took out the card that was in it and dimensionally it is almost identical to the HD 3450 so I started to swap the fan and heat sink off of the factory card and I have two capacitors in the way. I have enough room to move them to the other side of the board so I am guessing I can just desolder them and resolder them onto the back of the video cards board as long as I keep the pins in the same spot?

If you're asking me this ?
I'd say as long as there's room back there, and you pay attention to the caps polarity (if they have polarity), then, yes you can

momo · Post by **momo** » Tue Sep 16, 2014 10:19 pm

If they're surface mount caps, there won't be any pads on the back,

But I'm assuming they're the radial leads, pin-thru, yes?

I'll be back, either later, or tomorrow (after 12am)

Nah it is to late to mess around with that stuff tonight. I will probably try to relocate them to the other side of the board tomorrow after work. I don't see why HP would intentionally make it to where you could not use other graphics cards with this thin client but I guess stranger things have happened.

Well...look at what HP may have done in the BIOS of the T5730, limiting the 2nd RAM sockets larger GB size.

So -- ya never know.
BUT, if you find out otherwise, with the graphic-card, then the other person on that site with his GT7725 graphics problem, may have another reason it's not working.

You'd solve his problem

hi folks

i have soldered the resistors and capacitors
and i have got this shit:

with ram in socket 2 tk doesnt start
with ram in socket 1 tk start normally
but with ram in socket 1 and 2 starts and shows like the picture
i have tried to start without R473 but with socket 1 and 2 doesnt starts
where could i made a solder error any ideas ?
it looks like artifakts also memory error... i think somwhere a solder error...
but where

maybe C243 ? is atached on the images

but in t5730 not there

T5735 · Post by **T5735** » Fri Sep 19, 2014 10:36 am

Well at least it is sort of booting as you can see it trying to make the HP logo. Perhaps you have a solder bridge somewhere that it to small for you to see? I successfully put Win 7 64 bit on my new GT7725 yesterday but the video card I have wont fit in the expansion module so I am going to hunt on ebay for a cheap one that will.

Just curious but does it actually boot past the big white HP log screen even being artifact-ed like it is? Like if you have any sort of OS on your disk on module does it actually boot to that to where you can tell it is working? If you press F10 does it bring up the bios page where you can see a big blue artifact-ed screen?

momo · Post by **momo** » Fri Sep 19, 2014 11:48 pm

I'm also wondering, krzysiek841, have you tried a smaller size memory module in the
2nd socket?
The members on the polish modding site said it only worked for them with a 2GB
in the 1st original socket and a 1GB in the added 2nd socket.
Only a total of 3GB worked on a 32-bit OS

By the way, is your OS 32-bit or 64-bit
I just want to see if that OS bit theory holds up

If you are getting this far on a 64-bit OS, and no blue-screen,
something else is happening with the polish modding sites attempts.

i doesn't go after the hp screen and F10 don't work

i have inserted 512 and 1GB in the socket

i have asked about c243 not 247

the c247 i have unsoldered from the tk that i fucked up earlier

hello

i have looked one more time on all soldering pins etc
i found 1 bridge on the socket
now it sems to work normally with 1 and 2 socket ...

in 1 i have 512 and 2 1gb currently running gold memory testing tools
after will try 2x2GB

...did you also put R473 in this TC, ???
If so, where'd you get it from? .. The other damaged TC didn't have one.

It seems you don't even need the C243

I don't think that socket distributor sent me a 9.2 height socket.

Because, even bending the stabilizing tabs outward, the socket is still
not wide enough for the RAM holding arms to clear the socket below.

It isn't high enough either, not to touch the 1st socket,
when the gold pins are touching the board.

You must have received a higher sized socket than I did.

This sucks..!

That's possible.
I think my socket may be 8.0 height. It's just a slight bit too low.
I'll have to get my better ruler out to check.
(It has measurement lines down to 1/64th inch.)

I may be able to manipulate those PCB stabilizing tabs height to
make the slight difference usable, but with the RAM module
in the 1st socket, this 2nd sockets module holding arms can't fit,
... It touches the module below, before the gold pins meet the PCB,
after the plastic PCB guide pins are seated in the PCB guide holes.
(Actually, almost seated, 'cause of the arms not clearing the 1st socket)

momo · Post by **momo** » Sat Sep 20, 2014 5:55 pm

I measured the height, matching up looking at the spec-sheet.
The area on that sheet, originally stating it's 9.2mm height us only measuring around 23/64th inch.

Which is .3593 inch (9.12622 mm) according to the conversion site...
https://www.google.com/#q=mm+to+inch

Hmmmmm, it's close, but still too short for me.

It's possible I could push the PCB metal stabilizer tabs down a bit, to raise it.
I'll have to see if that still allows the gold pins to touch the PCB trace, and the
RAM holding ARMS to clear the 1st socket, but it's certainly not the part meant to fit
with the 1st socket, as a match for it.

The original FOXCONN matching part had the stabilizing tabs facing outwards already.
And most likely, had the correct height for the RAM holding ARMS to clear
the socket below, with the RAM module in it.

Oh well, I'll just need to modify it, or keep looking for another socket

Once it's in, I can't remove it, without a special SMD head for the Hot-Air soldering system.
I need to get this adjusted as good as possible if I'm going to use it.

T5735 · Post by **T5735** » Sat Sep 20, 2014 6:02 pm

http://d3oe7rwezamf3s.cloudfront.net/me ... nozzle.jpg

Yes, but it needs to be the full length of both sides pins.
The heat needs to be even across, or all the pins won't be lifted at the same time

momo · Post by **momo** » Sat Sep 20, 2014 6:10 pm

Then there's the problem with lifting the metal tabs too.

Usually, you'd remove the solder from the metal tabs first, using solder-wick.

I think there's a specially shaped tip to remove the sockets pins and tabs,
at the same time.
It may be expensive though, so usually it's done with what's available.

momo · Post by **momo** » Sat Sep 20, 2014 6:26 pm

I haven't seen any that matched the spacing for both width and length,
that was long enough, from stock tip suppliers.

Putting on the socket is simple, compared to removing it.

You just seat the socket, apply the solder paste across the pins,
with some resin to make it flow well, and not bridge,
then simply move the hot air around the pins, evenly & quickly, to heat all areas,
until all the solder looks shiny when melted.

If you have a solder mask stencil, you'd apply the paste first,
then seat the socket over it, and heat it, same as above.

I wonder if our friend was able to have success with two 2GB RAM modules in.
Otherwise, it's all moot.

T5735 · Post by **T5735** » Sat Sep 20, 2014 6:28 pm

With the pads already being soldered on the motherboard do we even need to apply solder paste? I have seen it done both ways on youtube and have been wondering about that.

T5735 wrote:With the pads already being soldered on the motherboard do we even need to apply solder paste? I have seen it done both ways on youtube and have been wondering about that.

You'd at least need resin, to re-activate the solder on the board,
but it's not good practice to do that.

Usually, all the old solder needs to be removed first, with solder-wick, for ideal connection specs.

But hey, ...this is us here ...

...so, I'm not going that crazy,
and will just use a small amount (thin line) of extra solder, on the pins,
but definitely more resin than what's already in the solder-paste.

The resin helps stop bridging by making the solder flow better around the pins.

If any bridges do happen, just a bit of more resin, and extra heat at that bridge, or wick off the excess, and heat the area again.

momo · Post by **momo** » Sat Sep 20, 2014 6:43 pm

By the way, my solder paste is in a push-type tube with a needle type tip.
Syringe
So it's basically easy to create a thin line of it across the pins.
Same for the resin.

hi gold test runned about 22hours no errors
i put 2 x 2GB in. The bios shows:

started mini windows xp from cd shows the same
but cpu-z shows ddr2 4096MBytes Dual ...
i tried to install win7 64bit - blue screen that the bios is not fully acpi compliant

i removed the second ram and bsod no more
after install will try to put it in again

ok i installed win7 x64 with 2gb ram then i put the second 2gb and i get a bsod again the - same one
i think its a compability problem how can i get the 4gb work ...
with 2gb in 1 socket and 1gb in second windows starts normally ...

Hi krzysiek841
The bios shows you still have a Sempron 32 bit processor in?

Or do you actually have a Dual-core 64-bit CPU ?

Because with my Dual-core 64-bit CPU I don't see it say Sempron CPU in bios,
it shows some other name.
