Question No post when cpu #4 is installed.

[mathiasd.hauge]

Hello, i have a motherboard that doesn’t boot when a processor is installed in socket number 4. (The motherboard support up to 4 cpus)

The pc boots fine when only 3 cpus are installed. I know that the cpus are fine because i have checked all of them in socket #1 and the pc still boots fine as long as no cpu is installed in socket 4.

I can’t see any bent pins in socket 4 and everything looks good.

When a cpu is installed in socket 4 i get no display. I have tried with onboard graphics and different gpu’s. So it has to be the socket, I have also tried with different psu’s.

the motherboard is a g34 socket and is called h8qg6-f.

First guess would be a power problem. Quad socket motherboards, generally have 1500W or more power supplies.
Second guess would be a RAM problem. Do you have at least 1 DIMM for each socekt?
Is this Intel Xeons or AMD Opterons ?

This is opteron 6386 SE engineering samples, I had all my ram in socket 1 so i will try to install a ram into each socket. Also, when i have cpu's installed in only socket 1,2 and 3, i get error beep codes if i dont install any ram, but when i have all cpu's installed, no beep codes occur even if i didn't install the ram.

I tried 1 DIMM for each socket now, still no post

Sorry, I won't help support engineering samples. I can't find an AMD policy on ES hardware, but I follow the Intel policies that ES hardware can't legally be sold and therefore I won't help support it.

I dont think amd has the same policy tbh.

I dont think amd has the same policy tbh.

Any text from AMD stating this?

In addition, ES chips are never guaranteed for any particular usage. They may work, that may work collectively. Or they may not.
