I've been running my server (S5500HCV) with 1 x E5504 (SLBF9) and 6 x 2GB Kingston ECC Ram for a few months now - finally decided to go out and grab another CPU.
So I went and got another CPU exactly the same (SLBF9) and threw it in there; shared 3 x 2GB sticks from CPU1 to CPU2 so each CPU has the same type, model, size and count of RAM (3 x 2GB ea).
Except - when I hit the power button it beeps 1-5-4-2 (Power Supply Assert). Take the CPU out - all good. Put it back in - same thing.
Now it's a 700W power supply - and I did my research before I got it too, it performs well under load according to several reviews (FSP 700W Aurum Series). I also have the P8 power connector in for both the CPU's.
The system has this additional hardware:
So I unplugged all the large sata drives (6 x 3.5") and take out the RAID controllers to test if it's a real power issue - but same thing, and I refuse to accept that the extra CPU drains the equivalent of 6 x 3.5" Enterprise HDDs and both HBAs on power-up....
Anyone have any ideas on what the real issue is?
Q1: Does this mobo require an Intel branded PSU (Like what's provided in an Intel Chassis) to properly operate in Dual CPU mode? I.E - Does the mobo require the AUX PSU 5-pin header to be actively connected to a PSU?
Q2: If yes, will any of these fit to the ATX PSU standard screw configuration? And do they have the 5-pin AUX output?
I had a P4 connector *NOT* a P8 connector in the second CPU +12v header - probably should have clarified that to begin with eh?
The mobo obviously treats the P8 as 2 x seperate P4's and errored because half the P8 had no voltage across it.
Thanks for your assistance Edward - nice to know Intel still helps people with gear that's 2 generations old, much appreaciated.
