Major problems with GA-870A-UD3 - Page 2

post #11 of 18
I have the same board and I can't get it to run RAM at 1600 mhz without increasing the voltage on the CPU-NB.

Being able to boot with 1 stick makes me believe this more. More sticks = more stress on the IMC.

Try to run the sticks at 1333 speeds and post again.

If you read up, our board is very picky on 1600 mhz ram. I think its just a design flaw (or not, since AMD IMC's are meant for 1333 mhz so it could be cost saving).

Also manually set the ram timings. My board's auto gives me weird timings which are nowhere near stock.

i could'nt get it to run at 1600mhz ever. but now i have exchanged the ram for some corsair xm3 and the computer is running fine now. But now i dont dare to overclock it.
My am2+ system was much more stable.

Congrats on stabilizing though!

Thanks .
I have tried overclocking some, to 3ghz. It's strange that it says my cpu vid is 1.475 (but its 1.35) and when i have the vcore set to 1.375 the vcore is fluuctuation between 1.25 to 1.38.....
I think this might be the worst mobo i have ever owned.

Even tho the computer is stable it feels really sluggish and slow, some programs might take 10 seconds that should take 0.1 seconds to open. Some program still stops responding but starts responding after a while.

the computer gets really unstable when overclocking over 3.0ghz, (have had the processor stable at 3.8ghz with an old msi dka790gx platinum that died on me)
I mean i thought gigabyte boards was good, always liked giga but never think im gonna buy one again -.- .

Hi all. I'm sad to say I am in the same boat as ye.
I bought my GA-870A-UD3 4gigs of ddr3 1333 ram and a gtx460 as an upgrade from my am2+ system. I was already using a phenom 965 in my cheepo MSI AM2+ mobo with a 150gig raptor and a 8800gt.
First second third ect....windows 7 64bit installs on the gigabyte all went badly. Errors like active logon failed, fail to activate, super slow response on first boot, straight into windows error fixing after first reboot and a lot of the time the network and home group section of windows install got skipped or failed while trying to connect to my homegroup.
Its the first mobo I have ever had that is moody. It can give two different results when installing windows the same way twice.
I have tried different bios versions. Different ram. 1066 and 1333. Different harddrives and an endless selection of different settings.
The main reason I am here is because I now have it running smoothly with everything working but it feels like someone swapped my 965 cpu for some 5 year old piece of crap while I was not looking. Mainly windows boot time. A normal user would think nothing of the boot time but I think its about 20sec more on what should have been a slower setup. Its the same harddrive, same cpu but am3 system with ddr3 ram. The bios boot screen goes and the windows logo starts to fade in and finishes. then there is 5 secs of doing nothing then a black screen for 3 sec then the windows blue logon screen for another 5 and so on ect.. On my AM2+ system the windows logo fade in did not have time to finish, blue windows logon screen for a sec and then on to desktop.
My head is wrecked about this. Its working but its not!!
I only bought the quad core 965 a few months before I got this mobo. It replaced my dual core 6400+. The snappy quick response feeling I got from that cpu upgrade is now long gone. I feel like I paid money for a system downgrade.
The worst thing of all for me is I am getting tired of upgrading computers and figured I would try and get a semi future proof AM3 system with usb3 and be done with it for a few years. Fat chance.
I have hated ASUS and MSI to a lesser extent in the past for the pain and frustration there motherboards have caused me. Gigabyte had never let me down. But that has all changed now. They have no forum at all. I emailed them about this back before Christmas and all I have received in response is an email saying that they can't email me for a few weeks but still no response.
The mind boggles. Rant over..
Believe it or not I had was just typing rant over and a girl a work with arriver over with my new BenQ G2420HDBL. All is good in life again. The scales of Justice have been rebalanced. That is until I go home later and watch my steam powered pc boot.

Well, i threw away that board and got myself a Asus 890GX board. So much more stable and overclockable.

Im sorry your all having the problems
i use f4 f5 was crap imo for bioses
i have had 0 problems with mine i run my ram at 1666 at 3.5, or 1702 at higher clocks fine
recently i lowered my timings from 9-9-9-24-2t to 7-8-7-24-1t, im using gskill ram the 1600 4gbrl models althought to get 4.0 stable and when i lowered my timings i had to up the ram volts to 1.60 then i upped them to 1.62 for piece of mind the sli hack works great on this board

to find the revision of your board its in the bottom left corner as your looking at it

On a side note the ram has to be in certain slots dep on what rev you have also all the drivers are revision based might wanan double check that cause i made the mistake when i first got it
and when i updated my bios i used the gigabyte tool from windows called @bios
make sure if your runnign in achi you have it set in bios and you install the drivers as your installing windows or you will get bsod's

another thing is when i updated my bios i checked the 2 boxes at the bottom of the tool forgot what there called but if you use it youll see it

and yes the auto timings on this board are crazy there somehtign like 7-7-7-20 you most def have to change that

Maybe it's a dead memory slot on the mobo? BIOS update needed? (BIOS update can stabilize memory issues sometimes)
Really, 1055T shouldn't have any problems until you're pushing 4 DIMMs at above 2000Mhz. I swear.
