Re: System Fault. No display nor beep sounds.

Deepu, you are a fool. This is a server motherboard and you are treating it like a PC. They are not designed to have keyboards and your suggestions display a total lack of knowledge on the subject. Give it up and go back to school.

Re: System Fault. No display nor beep sounds.

Here is suggestion: Disconnect the HDDs and other storage devices and then start your machine. If this does not isolate your problem. Try changing the keyboard. Hint: also make sure your motherboard is not touching the metal cabinet anywhere. If so it can cause serious damage to your system.

Can i put dual core processors in my intel se7505vb2 motherboard?

Page 16 of the Technical Product Specification guide;

3.1.1 Processor Support
"The Intel Server Board SE7505VB2 supports one or two processors in the 604-pin FCPGA package."

-> Socket 604,

-> Intel XEON processors ONLY

"When two processors are installed, all Processors MUST be of identical revision, core voltage, and bus/core speed."

-> Means you really should use two IDENTICAL processors.

"When only one Processor is installed, it should be in the socket labeled CPU1, and the other socket must be empty."

-> Self-explanatory.
That's the processor socket furthest away from the black AGP graphics expansion slot, and closest to the outside edge of the motherboard.
(Page 104, and 105)

ONLY supports Intel Xeon processors with a 400MHz, or 533MHz FSB.

Dual-Core Xeon's start at 667MHz, and wouldn't work anyway; due to different Core architecture, and Instruction Sets.

667MHz, 800MHz, 1066MHz, and 1333MHz, for dual core Xeon's,

(Scroll down just a touch, to get the Wikipedia 'banner' out of the way, or click on it's X)

Scroll down the page, look at the charts. Starts with 800MHz FSB for Dual Core, then goes 667MHz, 800MHz, 1066MHz, and 1333MHz, Front Side Bus.

Use Dual Core processors?


Two Single-Core processors.

My DG41TX works perfectly with dual core processors, but with core 2 duo not, do 3 beeps and dont show any video, what i must do?? my core 2 duo is E8400 my dual core is E2180 Bios Version:...

The POST beep code - 3 short beeps mean RAM failure.
Try reseating the RAM modules.
If this does not solve your problem then remove all the RAM modules and insert one RAM module at a time into memory slot 0 (1st memory slot) to determine which is the faulty RAM module.

MSI H55M-P31 board & having 2 2GB DDR3 modules and I7 Processors, installed memory on dual channel and sytem beeps 3 time and no display

Depending upon which BIOS make is installed in your computer, 3 beep means RAM fault.
Check the specification of your motherboard for the recommended RAM.
Reseat the RAM nodules in the motherboard.
Remove the RAM and get them tested at your friendly computer repair shop.

No display

Beep codes are usualy heard when there is a problem with either your display card or your RAM.

Your problem could possibly be a faulty CPU.
Does your CPU work in another board, or can you try another CPU in your board?

ASUS P5Q3 with Xeon CPU

Yes, it will work. However it depends on which one you buy. Here's one that will work with that particular motherboard.

First, visit this website. Now search for, "Xeon" (Without the quotes, though). Click the second result on the list, which should be the, "Intel Xeon E3110 Wolfdale 3.0GHz LGA 775 65W Dual-Core Processor Model BX80570E3110 - Retail." That processor is a 45NM LGA-775 processor, which Asus claims that motherboard can support 45NM LGA-775 processor.

Let me know if I can assist you further, or if I need to explain anything in more detail. If this solves your question, please rate the solution.
