GA-X58A-UD3 rev. 2.0 help - not seeing all memory

[jgranto]

I have a GA-X58A-UD5 rev. 2.0 motherboard, an i7-980X CPU, and G. SKILL F3-12800CL7T-6GBPI memory (CL 7-8-7-24-2N), all brand new. I hooked everything up, and the first time the system came up it recognized only 4GB of the 6GB of RAM. The stock BIOS (FA, I think) was not acting 100% fine - when I went into MB Intelligent Tweaker, then into MIT Current status, the keyboard would stop working.

I then checked the Gigabyte forum and this forum, and see that the RAM issue is not rare. The thread I read recommended I upgrade to the newest BIOS, which I did (Fb10). After installing it, the system would go into an long reboot cycle where it would say it was "Recovering lost DRAM size," which I never saw before with the stock BIOS version. If I let the system keep rebooting for a while, it will eventually boot up, and I was able to install Windows 7 Ultimate 64bit. Windows states that there is 6GB of RAM, but only 4GB is usable.

The thread I read talked a lot about using XMP and then setting things manually. Basically, I am not really interested in overclocking the CPU right now, and clocking the RAM at stock is fine as well. I just want the machine to recognize all 6GB of RAM and to be stable. I did swap out the keyboard with a better one, and when I got into MIT again, it stated that the system had rebooted several times due to overclocking, so the values may not be accurate.

Can someone talk me through the settings necessary to get the system reliable, or help me determine if I have a bad motherboard, CPU, or RAM? I am not familiar with overclocking, so bear with me if I ask basic questions.

Thanks!

One more thing I forgot to mention... for some reason, I do not seem to be able to reliably get into the BIOS setup (DEL key). With the second keyboard, it has a power LED. The one time I got into the BIOS without problems, I noticed that the LED was lit. However, most of the time the LED is not lit, and no matter how much I pound on the DEL key, it gets ignored.

In addition to the RAM questions above, is there some setting I can configure to make getting into the BIOS setup easier? I did not enable USB keyboard in DOS or anything.

Re: GA-X58A-UD3 rev. 2.0 help - not seeing all memory

you need to enable usb keyboard if your using usb,disable it only if your using a ps2 keyboard,what brand/model keyboard is it? as for the ram you might need to tweak qpi/vtt and set ram speed/timings manually without enabling xmp

The settings in the BIOS regarding USB keyboard and mouse have to do with DOS, so I was unsure if I needed to enable it. I am trying to use two keyboards, one is a Microsoft Digital Media Pro, the other a generic Dell with a smart card reader. Neither can reliably get recognized during POST to allow me to hit DEL.

I am not enabling XMP. Can you suggest settings for QPI/VTT and the RAM speed/timings? There are so many settings I do not know where to begin.

Re: GA-X58A-UD3 rev. 2.0 help - not seeing all memory

you need to set the dram voltage to whats printed on the module,something like 1.5v or 1.6v or 1.66v,then set the qpi/vtt voltage to around 1.30000v and change the system memory multiplier to give you 1600mhz speed or close to just change spd to manual and then the multiplier to 8x/10x/12x ect to raise the memory speed,then select quick for timings and manually type in 7-8-7-24 going down the first 4 in the timing list

Re: GA-X58A-UD3 rev. 2.0 help - not seeing all memory

I feel for you I have the same motherboard and bios is only showing 4 gigs and windows shows 6 but only 4 usable. I also have checked all the pins reseated CPU 4 times just to make sure and still no go! I think its the Bios or MB to tell you the truth. I have been running stability test with only 4gbs all day and rock solid but it bugs me that I can't use the full 6gigs when I check my graphic card it shows that 2 gigs as being there and I have no idea how to get it back. I have tried to reinstall windows 7 and everything.

what ram are you using? did you lower your qpi freq with the 980x chip? maybe its too high following the normal 2x+1 method,for the 980x chips you can use much lower like 18x

So far this processor has been the processor from hell lol however I pretty much have accepted that I won't be able to use the full 6gb :( If you see something in here that I can change please let me know and I will change. I did try and lower my uncore to 15-20 same problem.

Re: GA-X58A-UD3 rev. 2.0 help - not seeing all memory

Did you try QPI 1.25-1.425? You may just need more or less, or you may need to try Uncore 20 or 21 instead of 22.

Are you 100% sure you do not have any bent CPU Socket pins? If you are not sure please check, and take a few images from different angles and let us check for you.

It could also be the memory, sometimes a RMA replacement set solves this if nothing else does and you do not have any bent CPU socket pins.

Re: GA-X58A-UD3 rev. 2.0 help - not seeing all memory

Okay I'm going to take my CPU off again and try and take a picture for ya.

Re: GA-X58A-UD3 rev. 2.0 help - not seeing all memory

Be careful, and take images from a few angles under good lighting. Enable Macro on your camera if it has that setting.

What cooler are you using?

Hey these guys know what they are talking about when they say to check your pins if possible take pictures with a camera and show them because without out the help of admin here I would have thought all my pins were good. Now I can see all my memory 6gb and hopefully get this thing clocked VERY high. Good luck and if you want to share some bios let me know.

Re: GA-X58A-UD3 rev. 2.0 help - not seeing all memory

I found the problem - as indicated on other threads, this often happens when there are bent pins on the motherboard. This was my problem - I fixed the pins and the machine booted fine. I will be replacing the motherboard. Hopefully this helps someone else out.

Re: GA-X58A-UD3 rev. 2.0 help - not seeing all memory

Sorry to hear you had bent pins!

It's nice to hear you were able to fix them though! So why replace the board now after you fixed it?
