Thread: Gigabyte EP45-UD3R Not Posting

I just bought a GigaByte EP45-UD3R Motherboard and a E5300 processor with my old OCZ DDR2-1200 ram.

When I turn it on I get a beep out of the on-board speaker and all 6 of the LEDs light up, but nothing else happens.

I removed the memory and it beeps rapidly every one second continuously for about 20-seconds or so and then reboots and starts beeping over and over again.

Is that a sign of memory problems or cpu or mb? I seem to have lost my spare 2GB generic ram module so I can't test a different stick.

Also, I get nothing at all on the monitor it doesn't even kick on and then return in stand-by mode. It just stays in stand-by mode.

Several possibities: first - did this replace another MOBO in an existing case? You might just have an extra 'orphaned' mounting standoff from the old board; check cautiously that every standoff corresponds to a MOBO mounting hole - an extra will futz things up, and can kill a board...

Next, the standard strip down: Power down at PSU switch remove everything except
CPU and heatsink/fan (check carefully that the fan retaining pins are fully inserted, completely locked, and not cracked) one stick of RAM, in slot closest to CPU
video card and monitor connector (if more than one PCIe slot, again, in slot closest to CPU) all power plugs - 20+4 or 24, 2x2 or 2x4 ATX power, graphics card power case speaker and power switch connectors keyboard (don't need a mouse at this point)
place jumper on RST_CMOS pins remove jumper from RST_CMOS pins
power up at PSU switch power up by depressing case power switch.

If you get video, enter BIOS with <DEL> (may need a <TAB> to get to POST screen, if 'splash' screen is enabled)

Select and execute "Load Optimized Defaults" - save and exit, reboot power down
reinsert other components, one at a time, testing each time after addition.

I think the memory is quite suspect however, and is likely not getting sufficient juice to run.

You'll need to borrow or buy a single stick of RAM that will run at 1.8V and adjust the BIOS manually for your RAM.

OK, I went down to OfficeMax and chosen up some DDR2-800 CL6 sticks with same results. One beeps and it just sits there with lights and fans on and no monitor signal or post codes. All 6 LEDs stay on.

Doesn't matter if you have MOBO rev 1.0, or 1.1; both have support the 5300 since F4, November '08; we have found that some OCZ 1066 wants to run kind of hot (2.15-2.20V) on P45s - I've not yet seen anyone try any 1200; that said, still - all RAM should be JEDEC spec in the base SPD - 800 @ 1.8V, and the system should accommodate it; have you tried a CMOS reset?

Did you put in a video card and plug it in? You never know. 1 beep generally means it posted just fine, i suspect bad monitor connection, cable, and monitor?
