"A possible VRM 0 has occurred"

VRM = Voltage Regulator Module

Here is what the motherboard looks like,

[Note* Posted for photo reference only. Not for advertising.
Besides, I do not see any VRM's plugged in. Means you get the motherboard only, and no VRM's. You need a VRM ]

What the Voltage Regulator Module looks like,

http://www.thebestpartinc.com/kg229.html

(Again, not for advertising. Click on the photo of the VRM to enlarge)

Notice that your motherboard has two VRM's. This is because there are two Processors.
Apparently the VRM for one of your Xeon processors is bad. (Z-on)

Since it states VRM -> 0, it is for the Processor 0, or in the number 1 processor socket.

What does a Voltage Regulator Module do for a Processor?
Regulates voltage.

A Processor MUST have a steady, 'clean' supply of voltage, AND it must be within the voltage range for the processor.

Since the motherboard uses an Intel E7525 motherboard chipset, it can support Intel Xeon processors, with up to an 800MegaHertz Front Side Bus. (800MHz FSB)

Looking at a typical Intel Xeon single-core processor, with an 800MHz FSB, let me show you it's voltage requirements,

1.287 to 1.400 (DC)

May be just a bad VRM.

However, I would also like you to look at the Electrolytic Capacitors on the motherboard. From what I have seen, those motherboards are notorious about having capacitors go bad.

Intel D845GVSR,

http://www.intel.com/p/en_US/support/highlights/dsktpboards/d845gvsr

Doesn't have a Voltage Regulator Module.

It has a motherboard voltage regulator circuit. It is integrated into the motherboard, not a separate module.

You will have to find the components, in the motherboard voltage regulator circuit, yourself.

How?

Electrolytic Capacitors are the weakest link in the motherboard voltage regulator circuit.

Part of what the motherboard voltage regulator circuit does, is to regulate voltage for the Processor.
Just like a VRM does.

A Processor has to have a steady, 'clean', supply of voltage, and it MUST be within a VERY small tolerance range.
Cannot be too much, or too little.

Its not booting and the Leds VRM and NMI are with amber color


VRM and NMI lights lit usually indicate an issue with CPU #2's VRM which can be replaced. Also check 5 lights on back middle of system. If VRM light is lit here remove CPU 2 and VRM and reboot system. If system boots, this was the issue...

Adding second CPU


Hi

Did you receive a VRM with the the PRC upgrade kit? And have you installed it?

The following items are/should be included in a microprocessor upgrade kit:
• A microprocessor (PRC)
• A heat sink
• Heat-sink retention clip(s)
• A voltage regulator module (VRM),
Your upgrade kit may also include a cooling fan.

If you are adding a secondary microprocessor, examine the VRM to ensure that it is the correct VRM for your system. Install the VRM in the appropriate secondary VRM connector, ensuring that the latches at each end of the connector engage. If you received two VRMs with the upgrade kit, replace the primary VRM already installed in the system with one of the VRMs from the upgrade kit.
Note: The system does not support mismatched VRMs.

Possible VRM 0 failure


69bf9f3.jpghi dear
Short for voltage regulator module, a small module that installs on a motherboard to regulate the voltage fed to the microprocessor. Nearly all motherboards have either a built-in voltage regulator or a VRM, the only difference being that the VRM is replaceable.
the cost is about $80 USD
