Quote from: tangram on May 28, 2015, 04:38:12 amHello,I'm having really bad issues with a Z800 mobo. It's taken out of a working system so I'm sure the parts are ok.Board revision is A02, it has 24Gb in 6x4gb modules. CPUs are X5550s. I've bought the adapter cable from the chinese guys PSU is a 485W Enermax. I know it's low but I wanted to see it go into BIOS before investing in a new PSU.My problem is that after connecting everything and starting the PSU, the board powers up(by itself, no pins or buttons), psu fans start spinning and it just hangs. No signal on video. Heatsinks, gpu, memory start to get warm but nothing else happens.I've tried using only one cpu, one ram stick, with gpu, without gpu, nothing. I really don't know if it's the low power of the psu or it's the adapter cable or something else.

I don't know why it starts when i flip the switch on the psu.The psu is this one:http://images10.newegg.com/NeweggImage/productimage/17-194-009-05.JPG

QuoteFront Panel:I caved and bought the HPZ800 front panel connectors. I tried and tried with the schematics that were posted, and the front USB ports DID work, but the main thing was I was still getting those BIOS errors. I wanted the BIOS errors to go away more than I wanted use of those front panel ports.Full boot up/restart without any intervention, success!
QuotePower Consumption:A (generic) kilowatt meter says that the system alone uses 300W to boot, 250W on no load and 475W on load (Prime95). It is an 80+ Bronze 1000W Power supply. With a single 19" LCD monitor, USB Powered Hub, IR Blaster, 1 externally powered TV Tuner (plus another internal), 2 cable boxes and DSL Router, total power consumption on load reached 520W max. Over a 24 hour period the system uses 30kWh. That does not include 2xCRT monitors I use with the computer that is not connected to the meter (and that I would not connect to a UPS, if/when I do get a UPS). Electricity costs US$0.06 to US$0.20 per kWh right now so the overall power bill is not bad.
QuoteOther issues:Every other hot restart recently I get an error at CPU0 DIMM3. If I pull the plug, let it rest for 5 seconds and power on it boots with no errors. I exchanged a stick from another location and I still get that error at the same location.. (so its location rather than the RAM stick). The 92mm fans are resting on the CPU heatsink (not tied down to anything) and are blowing right on the sticks. Temperature of the RAM never cross 52degC under load so I am thinking my power supply might need to be upped again. I previously got memory errors with underpowered power supplies.... or is it really that the memory is bad? Soon I will disconnect everything and run full memory tests.. I am dreading it because my RAM is no longer under warranty.Again if I knew now about what it takes to do this hack I would skip it and just buy something already put together, even used. Sky box (Freight forwarder) charges for this build were US$350 with the total cost being US$1670 for only 24GB, Dual 5550s, 256GBSSD, 2x3TB HD, 2GB GT730 Video Card. A proper case, Monitor, KB+Mouse, and UPS is still not included in the cost. I can't resell unless I get a proper case. My fastest computer before this was a 4GB Core i3 Laptop that could barely handle a single SDR trunking decoding session. Before I had 3 dual core computers and a laptop running continuously. Now I only have this one so I could prepare the others for sale. The HP Z800 hasn't failed in any operation I have thrown at it. I use it mostly remotely for several VMware Workstations and dual TV streaming when I am away from home.No pictures of most of these updates because I have no camera... I sold my phone to my dad to pay for the additions so all I have now is a non touch VGA camera phone with no flash!! I'll post more pics when I could get the phone borrowed.
Quote from: knightcrusader on May 28, 2015, 04:36:56 pmCome to find out, the firewire pins are pretty much standard, except two pins are duplicated for ground and power. I assume that is what it uses to figure out if its connected or not. I made an adapter that plugs into that and then the standard firewire plugs into that, and it shut it up after one reboot.
Quote from: BenGman on May 28, 2015, 08:11:19 pmWhich two pins? I had a new 5.25" front panel with firewire purchased 8 years ago, 2 different firewire MB adapters (which were underwater for sometime in a 3ft flood I had home) that didn't work... so because of age and possible water damage I still went and bought a new 5.25" front panel to try the firewire (and the new one had USB 3) and it still did not work. The case's front audio didn't work and neither did the audio on both front panels (still got the BIOS message). USB front ports worked but I still got the BIOS error. So all three USB, Firewire and Audio messages still appeared in the BIOS for me so that's why I got HPZ800 front headers. I purchased it from the UK (had it half the price as US) and I had it shipped straight to me instead of going through my US skybox. Purchases from the UK used to arrive within 1 week... this time it took 4 weeks. So to reach the no F1 prompt took 3.5 months!If I lived in the US/UK it would have been cheaper. If I want to ship a paper clip it costs me US$10 + 3 weeks. I have to pay different freight+VAT+Tax on each small package. So all the different shipments from different suppliers that I needed to get parts.. plus the time to get them here cost too much time and money. If one supplier had the MB, RAM, CPU, MB power cable etc... then it would have been a lot cheaper. So for this project I should have just bought the refurbished 24GB, Dual 5550, in a proper HP case with everything in one package (MB, case, PS, front connectors, fans, etc)... that would have been US$400 for the unit then ~only US$220 freight+tax&vat.

Quote from: tangram on May 30, 2015, 03:17:50 amI tried using another psu I had around. Same result, no video signal

Same result, no video signal Do you have another graphics card that you could try? Your symptoms sound vaguely like what happened in my early tests with the 7970 though that card is now working perfectly.
