Help?: ASUS P6X58D-E not seeing 12 GB of ram

post #1 of 12
Thread Starter 
Desperate here and I'm hoping somebody can help. I have an ASUS P6X58D-E that I bought about 8 months ago with an intel i7 930 and 3 sticks of OCZ 2GB DDR3 memory (OCZ3G1600LV2G). I was happily getting 6 GB of ram displaying in BIOS and Windows 7 64 Bit Enterprise.

I decided to double the ram so I bought 3 more sticks of the exact same RAM but I've never been able to get it to see more than 8 GB in BIOS or Windows, even though PC Wizard shows 12 GB (see screen shot below).

I went through the basics of swapping out the sticks and moving them but no luck. I have updated through each BIOS version that has come out (just updated to the latest 6.02 this morning) and I followed ASUS' Recommendation to clear the CMOS.

I did that and now my MOBO powers on for about 1 second (fans all start spinning) then shuts off for about 2 seconds (fans die) and then boots up normally. This is weird and bothersome and yet I still see only 8 GB of memory.

I'm not clever enough to understand all the manual memory settings and timings that I've seen posted online and I'm hoping that somebody might be able to tell me exactly what I need to set the BIOS settings to in order to see all my memory. I'm not looking to OC per se....I just want all the RAM smile.gif

Below are my PC Wizard Settings and you can see that 12 GB are visible there. Any thoughts?

Check the advanced boot options.
1. Go to Start, in the search bar type msconfig and press enter.
2. System Configuration window will open on the screen.
3. Click on tab named "boot".
4. Click on "Advanced Options" and uncheck the box for "Maximum Memory".

That should fix it for you.

Thanks for the fast reply but I should have mentioned I checked that already. Also, BIOS isn't seeing more than 8 GB so I think it's something in the BIOS Settings.

I do appreciate the reply though!

But this "Maximum Memory" option "Specifies the maximum amount of physical memory used by the operating system to simulate a low memory configuration."

So how would it fix it?

My bad. A little long post, so I skimmed it.
It says that it sees 12GB's of RAM but it does not see slots 0/1.

Yeah I noticed that as well which is doubly confusing to me. The total RAM is 12 GB though.

The link is appreciated. Unfortunately, this reads about as foreign to me as all the other info I've found online. I will admit it's beyond my mathematically-challenged brain to work out all the math. I'm hoping somebody has this MOBO and similar RAM and knows exactly what the settings should be. eek.gif

If I were you I would read some of the guides posted online about overclocking to learn a bit more about the BIOS settings of your board. Also go to your User CP and fill in your system specs.

You should dial in your RAM settings manually, to ensure your RAM is being used to it's full potential. If you can't use all of your RAM you should put some extra voltage in the DRAM field. 1.64 should be enough, but you might have to change the timings and the speed if you still can't use it.

BTW i'm not saying you should overclock if you don't want to, it's just that in the overclocking guides it usually explains what each settings in the BIOS means and what voltage you should use.

Please read that guide, as it outlines the problem. Every piece of hardware is different and no one can tell you exactly what settings to use.

When this happened to me, the CPU wasn't sitting right in the socket. Try reseating your CPU and don't overtighten the cooler too much. This may fix it. Then try 1.4v QPI/VTT voltage. But every CPU varies, this is why I'm telling you we can't tell you what to do. Every CPU has an optimal ratio between the QPI/VTT and DRAM voltage, like in the guide they give a good example:
Quote:
Example, say you have 6x2GB @1333mhz working fine at 1.35v QPI/DRAM with 1.65v VDIMM. You try to overclock the memory to @1600mhz speeds, and you bump VDIMM from 1.65v to 1.75v and now only see 8-10GB detected. You've moved out of the optimal differential range for QPI/DRAM to VDIMM which @1333mhz was 1.65 - 1.35v = 0.3v. At 1.75v VDIMM you left QPI/DRAM at 1.35v so 0.4v differential voltage. Then you bump QPI/DRAM to 1.45v to keep 0.3v differential voltage and 12GB is detected again. Now this is just an example, it could be you need 1.85v VDIMM for your memory to be stable and if 0.3v is optimal differential voltage it means you need QPI/DRAM set at 1.55v

My CPU works good with an offset of ~0.22v between ram voltage and qpi/vtt , but yours and everyone elses is probably going to be different.
