EX58 UD3R failure - debugging? - Page 2

Last message on previous page:
Is it too late to join the club? Just assembled the box below. The thing will not POST or show anything on the display.

My problem is similar to the original poster's... except I don't have the continual reboot. Everything powers up... all fans spin. Every 10-15 seconds I see LEDs on the GPU flash and the fan speeds up for a couple of seconds then back down to the original speed. I've tried the card in both slots. Its not the PS (tried another).

I tried a single RAM stick, though I'm not sure I tried all the sticks individually. Whats the story with RAM compatibility for this mobo? I'll be really cheesed if the RAM isn't compatible as I bought the mobo and RAM as a recommended combo from NewEgg.

MOBO: Gigabyte GA-EX58-UD3R
CPU: Intel i7 920 @2.66
RAM: 6GB (2Gx3) OCZ OCZ3G1600LV6GK
GPU: Asus EAH4870 1GB
PSU: Raidmax RX-700SS
HD: WD Velociraptor 150GB
OD: Samsung SH-S223L
Case: Antec Three Hundred

FOLLOW UP: Based on a suggestion above, I reset the BIOS (removed the BIOS battery and left it out overnight). Box would still not POST or boot with all three RAM sticks in.... However, it WOULD now boot POST and boot if I had a stick in just DDR3_1 and DDR3_2. If there was ANY stick in DDR3_4 it would not POST at all. I tried all combination of two sticks in DDR3_1 and DDR3_2, booted and ran 4 passes of memtest86 v2.11, so RAM was good. Looks like a bum initial BIOS configuration (???) and a hard failure on RAM slot DDR3_4. Mobo is on its way back to Newegg for a replacement.

Hello everyone,

I just have a similar problem as everyone else here, thing is that after getting those continuous beeps (accordingly to manule a power problem) the system can boot as normal and go into Windows, then I can work and do gaming for hours with no problems at all, should I just get used to it and live with it? think something is not working perfectly and the systems just warning me so seems there is something I should fix.

Please any comments will be much appreciated.

Thanks for asnswering, but I have already read that suggested thread and have found no answer for my problem as stated, seems everyone simply cannot even boot the system, and my problem is not exactly that, I can really boot my system, the only think annoying is that before the system boots I get these continuous beeps, and then the system just starts, I just wanted to know if someone has had some similar experience, thanks for the support.

Hi - not sure if this was mentioned already or not.

Apparently, there's a compatibility issue with this motherboard and some POWER SUPPLYs.

It's not a RAM or CPU issue (although some RAM isn't compatible either, but that's not uncommon with mobos). For some reason, certain Power Supplys can cause occasional or looping reboots pre-POST with this motherboard.



I use an Antec PSU and my board works fine - I did have a single auto-reboot maybe one time upon turning on the PC, but I thin it was a self-correcting reboot to re-regulate some sort of power issue and after that one reboot it's worked fine ever since.


However, some people with other PSUs have reported unlimited reboots without being able to get into the POST or BIOS. I'm not exactly sure what is going on in certain PSU's that is causing the misfire. Whether it's a delayed fan spinning or a regulation anomaly or what - but the motherboard is seeing it as an issue (think false-positive) and it triggers a reboot. Usually after the reboot, the PSU is up and running at full speed and there's no anomalies and it goes right into the POST and then loads the OS. But I'm just guessing on this.


If you're willing to be patient and have the time and extra PSUs laying round, I suggest trying different PSUs to find one the works better. (Antec PSUs work pretty good with this mobo, from my own experience - I've used an Antec 450 Watt True Power and an Antec 650 Watt True Power with it and both booted fine without issue. My older 350 Watt Thermaltake PSU, however, had a couple reboots - but it might not have had enough juice to handle all the hardware.)

Or if you don't want to bother with it, maybe get a different board. Depends on your patience level. This is a great board and the best overlocker IMO. Can't beat the price. But if you don't feel like doing trial and error with swapping out PSU's, then you might as well just pay extra for a different board.


Just something to consider.

i seem to be having the same problem with the gigabyte mobo. just boots, 4secs shuts down, starts again, shuts down etc etc. i did have it up and running with xp but found that if i used the Easy Tune software to overclock in windows it greyed out all the bios screens?? while putting a 32 bit Vista system in it started the boot/restart problem. i now have no sight of the boot screen. Have reset cmos and changed the power supply without any luck. i got my stuff from Scan.co.uk and have arranged to return the mobo but during a call to them they assured me there were no problems emerging on the mobo. I mentioned that the forums were saying otherwise and they told me that forums were not to be believed?? my set up is an i7 920 processor, 3X2gb crucial ddr3, gigabyte mobo,titan fenrir cooler and 8800gt graphics

Did you review the read me first stickee on what do do if you have boot issues?
That is the starting point. Its in the Homebuilt forum so you might have missed it - the link is below.
