    hi profJim,

    Have posted the specs now. Please see my reply to parsec. A number of components haven't been installed yet because when I tested the system (after installing the the CPU and RAM and plugging in the power connectors) it didn't work. There seems little point in complicating things by adding more components to a system that won't POST with the v1.01 BIOS and won't allow connection of a SATA drive with the v1.03 BIOS. Add-on cards will not be installed until the system is working without them. The SSD won't be installed unless I have a working computer with all other hardware installed and the operating system and programs on a temporary drive. Then that will be cloned to the SSD.

    I would be grateful for any help.

    Your approach makes sense, using a minimalist approach when installing hardware.
    Section 2.2.3 in the Asus mobo user manual recommends the following:
    • a2 memory slot when only one memory module is installed
    • a2 + b2 when two memory modules are installed

    If you've tried each module, one at a time in the a2 memory slot and your system won't post, the a2 slot is probably defective.
    Closely inspect all memory slots and make sure that they don't have any debris and that each electrical contact is not bent or damaged in any way.
    It's unlikely that the a2 slot will work if you test with one or more of the G.Skill modules.
    Q-code 55 = memory not installed indicates that there is a problem with the memory slot or memory module.
    It's possible that the memory module is not fully seated, but it is unlikely that this would happen with the a1 and a2 memory slots, but not with the b1 and b2 slots.

    Double check that the 24-pin and 8-pin EPS12v power supply power cables are fully seated.
    Did you use the same power supply with the Asus and ASRock motherboards?

    This is a long shot, can you test with a different power supply?

    **edit**
    There is a 4-pin EZ_Plug molex connector next to the 24-pin connector.
    Check out the MemOK! switch information on page 2.10.

    Have tested both the Corsair and the G.Skill memory kits on the ASUS board and found that all modules will work in the B slots. I think that only leaves the A slots as the source of the problem with the ASUS board. As you suggest I'll give them a closer inspection tomorow (in the clear light of day). I'm always double checking that memory modules and power connectors are properly seated (to the point of being obsessive), so I don't think that is a problem. The 4-pin EZ_Plug molex connector is connected and I've tried the MemOK! switch without any luck. That didn't really surprise me because the memory should be compatible anyway.

    As for the Asrock board, your long shot may be close to the mark. When I first installed the ASUS board it would consistently shut the computer down before completing an OS install due to a reported power problem. A change of PSU fixed the problem. But because there isn't a spare case for the Asrock board it hasn't been tested yet with the new PSU yet. Will test it tomorrow and let you know the result. I'm not hopeful though because the ASUS board worked with the old PSU if the Anti Surge Function was disabled in the BIOS and that PSU is still working as a replacement PSU in a P5N72-T Premium system (my shed computer), without any problem.

    In rare occasions, some psu brands or models have compatibility issues with some motherboard models, even when a good quality psu is used. Power supply issues often cause problems that don't appear to be caused by the psu. In one thread, the OP had problems where his motherboard bios appeared to be bricked. He didn't have access to other hardware for testing and his only option was to take his system to a local pc shop. I suggested that he take his psu for testing also. Instead of RMA'ing his motherboard, the shop found that his system was fine when they tested it with a different power supply.

    I recently bought a $20 psu tester, but this will only confirm that some of the voltage settings are OK. It doesn't tell me if any of psu circuits are able to deliver the correct amount of power (amps) or if the electrical power is out of spec. I can get the same information by using a DMM (digital multi meter) to check voltages, but it would take much longer using the DMM.

    When building a new system, I always set the motherboard on a cardboard box that is placed beside the computer case. I don't install the motherboard in the computer case until I've finished installing the operating system and performing several hours of stress testing. I've recommended in some threads that the OP should remove the motherboard from the computer case and use a minimal hardware setup to help diagnose which components are causing the problem.

    These are two of my posts that I frequently link to:

    Hi profJim,
    A big thankyou for reminding me of the importance of testing a system with a different PSU. I re-installed the Asrock board (with original BIOS P1.10) with all four Corsair DIMMS and the new PSU. The computer did what it always did before - stopped at "0d". Then I replaced the BIOS chip with one of the two (P1.30) that Asrock Tech Support sent me and tried again. This time it worked and has ever since. So the problem was actually a combination of a faulty BIOS chip and a faulty power supply.

    Now to the ASUS board. I gave it as close an inspection as I can with my aging eyes and it appears that there is some irregularity in the cpu socket. I don't think that it is a bent pin, though. I'll need a magnifying glass to know for sure. Will let you know when I know more.

    You're welcome, glad to hear that you're making progress.
    Can you take some high resolution photos using macro (close up) mode of the cpu socket?
    It's important that you have even lighting from both sides and that you don't use the camera's flash.

    We've spotted bent cpu pins that others couldn't see.
    They posted a link to the full sized photo that was available from DropBox or other file sharing sites.
    It's also a good idea to inspect the contact pads on the underside of the cpu to verify that each pad is making contact with its socket pin.
    If you've used the same cpu with both motherboards, the pad check probably will not be useful.

    Enclosed is a cropped and resized high resolution photo with 2 bent pins.

    I couldn't get any photos that were worth showing you. The problem was a single pin in the top row that was sticking up. Maybe it was a "bent pin" or it might have been a manufacturing flaw. When the cpu was installed that pin would have been outside of the edge of the cpu and so was not being squashed flat by the cpu. I was able to push it back into alignment, then install the cpu and on the first test all memory modules were detected (for the first time slot A1 and A2 were working.

    I find it a little hard to believe that I bent a pin because it's never happened before, but anything is possible. And I was a little surprised to find that the supplier had included a printed page stating that: "If you damage a pin, this is not covered under the manufacturer warranty" and showing a couple of photos of CPU socket pin damage. I would have assumed that anybody building a computer would be aware of the need to take care when installing the CPU and not need this extra warning. It makes me a little suspicious as to the reason for including it. Was the board already damaged when I received it? I guess I'll never know.

    Thanks again for all your help.

    You're welcome, glad to help out.
    It's possible that the bent pin came that way and that you didn't notice it when you first installed your cpu.
    With brand new hardware, I always perform a thorough inspection to verify that there aren't any obvious defects.
    Sorry to hear that both of your problem motherboards are now working perfectly.

    Wow, what a story! So can we conclude it was the one bent socket contact only, or that plus the bad or incompatible PS?

    The damaged socket pin not being covered by warranty is a fairly standard thing, although how FAIR it is, is debatable. I've read forum posts where users RMA's a board, and it was sent back with a note saying damaged socket contacts, not covered by warranty (aka, you are SOL.) The electronics store Fry's, when you purchase a mother board, has you inspect the CPU socket when you buy the board, and sign off on it as Ok. Yes, standing at the checkout in a store with no more than your eyes is the best way to check a CPU socket... NOT!

    I've seen the pin maps of Intel CPU sockets, and power and ground contacts can use ten or more pins, no surprise there. A few seem to not be used.

    But consider that the one special contact that was damaged in Robert's situation was the problem. That is one contact out of 1,155! In case you don't know, the socket numbers are the number of contacts in the CPU socket. Now consider socket 2011, with 2,011 contacts! How do these things work? How can the sockets be manufactured at a decent price?

    I'm not a religious person, but I like to say the proof of God's existence can be seen in the miracle of risen bread, and that computers and the Internet actually works.

    Thumbs down Re: New build gives six beeps, won't POST

    Gigabyte is the only one that I know of that regularly fixes bent cpu pins for free under warranty.
    As always, each mobo manufacturer has their good points and their bad points.

    I'm still holding my breath and waiting for one of the major manufacturers to finally see the light and recognize that their sales will skyrocket once word gets around that they have a superb tech support department that responds quickly, provides excellent service in all major languages and builds a loyal following where their customers know that they will be well taken care of when problems arise.

    Yep, I know, it's a hopeless pipe dream.
