If only my precious hp z600 could've supported the higher chips, sigh, I'm enjoying this dell t7500 although

The T7500 is a solid machine and still holds good performance to this day.

There's not need to rush. Just be careful and bend it just a little bit at a time.

Bodge wires are always a valid solution if they get the job done. It does not have to be pretty as long as it works.

not sure if I fixed what you guys were looking at but here are updated images, also do you guys think making it boot off a drive that has windows 10 installed is alright? (unsure of that can be a problem)

Looks ok. Have you boot tested it yet?

Shouldn't be a problem.

same problem tried 2gb and 4gb ram to, this is the setup i have for it. not sure if it wants anything. Gives 2 beeps then stays on with lights green on 321, green power button after turning off and on 3 times

Ah, pictures tell a tale. The CPU heatsink is mounted off center. From the angle of the above photo, turn it 90degree to the right. The notch that is molded out of that one side should be next to the VRMs. Also, do you have any non-reg, non-ecc 1gb or 2gb DIMM's to test with?

fixed the heatsink, for the ram I don't have any..how did it boot that one time even

I wish I was there. What you need is someone to get hands on with it.

I mean I have experience with computers but never experienced something like this given I read that this board is very strict and hard but wouldnt think it would be this hard. So i am lost on what to do now. brought two seperate x5680's , ECC ram and REG ram , heatsink, new cmos battery,new caps,cleaning supplies, Thermal grizzly paste for processors and chipsets. I don't want to give up on it yet since it gave me that one single sign of it posting and attempting to boot into win10

It could be a bios setting that is messing with you. Have you tried resetting the bios? I can't remember whether we'd tried that yet.

 

[MrJunez]

Just tried it now and its just turning off and on till it reaches the same numbers and stays on from there, same thing basically. Things I tried 1: Switching Processors out (both processors are x5680's) 2: Adding fans in incase it wants it. 3: replacing one of the caps that were broken off and not making contact anymore (16v 470uf to a 35v 470uf) 4:Switching Ram Between 2gb,4gb,8gb (ECC and REG ECC) 5: resetting bios 6:Replacing Cmos battery (when it posted the single time it told me battery voltage low) 7:making sure it has new thermal paste 8:Soaking the socket,Rams slots,pcie slots with 99% iso alcohol 9: fixing a socket pin 10:Trying ram only in DIMM1

Been messing about today making a new home for my server and Nas.

I'm out of idea's. Not sure where to go from here with that board.

Hmm, well I don't want to throw this board away so I'm going to keep it until maybe someone has something for me to try out or if i fix it myself one day since it gave me life for a second. I have been told that the caps are Low ESR caps so I need special ones otherwise I'd have boot problems or other problems so that can be one reason why It doesn't want to boot. DocVolt from The Rossmann Group Discord said "
That's a question you'll find on the test I'll let piernov explain since he's way better than me at this. It stands for equivalent series resistance. Basically a capacitor in a perfect world is just a capacitor, no resistance. 0 ohm in series to it. So basically there's not a resistance in the circuit where the capacitor is. But in the practical world every capacitor "comes" with a little resistance/resistor in it. Which can be drawn in a schematic as a resistor in series with the cap
Shit capacitors usually have enormous esr values, which can be fine for some toys or bs. But for caps filtering stuff on a computer board that's a big no. Low esr caps are more expensive and designed to have a low value of ESR. you want those in your board
Using shit caps can cause crashes, no boot, weird shit and all that comes with it
With aluminum electrolytic caps, like those you are trying to replace, this resistance increases over time of use. That's why I was saying about buying new stuff. But piernov is correct in saying better an used low esr cap than a brand new manure filled aliexpress or Amazon special offer capacitor"


Anyway other then that, is there any motherboard I can buy that would serve me as a server to run a website off of? I have these ram and processors laying around and want to use it. preferred a dual socket since i have 2 x5680's

You could find a T7500 that is in good shape. Or even an HP workstation.

does a motherboard on a T7500 use the same parts as a T5500? Like Power supply etc, I'm thinking about buying the mobo itself

There are some subtle differences. If you already have a T5500 case, it might be best to just get another T5500 board for it. They're not expensive.

Whats the difference between a T7500 motherboard and a T5500 motherboard? do they take different parts from eachother or is it specs? I also don't have a case so I plan on using the parts to fit it in a aftermarket case preferably for better cooling (a 4U server rack case)

 

[lexluthermiester]

Whats the difference between a T7500 motherboard and a T5500 motherboard? do they take different parts from eachother or is it specs?

I'm gonna take that back. I was thinking of the differences between the T3500 & T5500. The T5500 & T7500 are nearly identical. The T7500 has Firewire and heatsinks on the VRMs as well as a few differences in the bios but other than that they're the same.

I also don't have a case so I plan on using the parts to fit it in a aftermarket case preferably for better cooling (a 4U server rack case)

I don't think that'll work. 4U server racks have a form factor different from the ATX form factor of the T7500 board.

what kind of case does the T7500 board want?

 

[lexluthermiester]

Some ATX cases might work if they have enough internal space but EATX cases would be best. However, the front panel connectors will be needed.

oh thats fine. I can do modifications to a case if needed. I love building sleeper PC's so am used to modfiying old computer cases to fit modern parts. But another question is will the T7500 board take T5500 board parts? Like front connectors etc

I'm pretty sure both t5500 and t7500 both take the same riserboard I'm fairly certain although double check this.

 

[Susquehannock]

The T7500 board is different in that it has built in SAS controller above the northbridge, and an extra set of connectors for it. Upper edge of board has different shape and screw locations to match.

That troublesome T5500 board probably has bad capacitors even though they appear fine. Can see it has the infamous brown United Chemi-Con "KZG" series. Same ones which nearly destroyed Dell. When looking for another board my suggestion is to stick with the latest revisions. T5500 = CRH6C. That way you will get the better Rubycon caps.

P. S. - if memory serves the T7500 riser is different part number than T5500. Mainly more memory slots and larger fan which will not fit into smaller more narrow T5500 case.

 

[lexluthermiester]

But another question is will the T7500 board take T5500 board parts? Like front connectors etc

The front panel connection I believe are the same. But the CPU risers are not, as detailed above. They are model specific and even motherboard revision specific for the early runs of the T5500.
