System Not Seeing Full Ram

post #1 of 10
Thread Starter 
I'm running 6gb of OCZ gold triple channel DDR3 with Windows 7 Home Premium 64 bit. The Problem I am having is that after I boot my pc, my system will often (50% of the time) read that I have 6 gb RAM installed but only 4gb is usable (or worse, but much less common, only 2gb usable). My RAM is set up in triple channel arrangement on my X58 FTW3 board. I've reformatted 3 times since having this issue (for other reasons) and this problem still occurs.

I can generally fix the problem by rebooting but its kind of hit or miss. Sometimes I have to reboot several times to get the dice to land with the "6gb side" up.

Thoughts?

BIOS update?

That's OCZ ram for you. I had the same exact problem with 12gb of OCZ gold...constant errors, only half or less of my ram being recognized, and blue screens a plenty. Your best bet would be to sell it in favor of Mushkin/Patriot/Corsair ram. I've had zero errors with the Dominators I put in months ago.

Try a bios update as mentioned above. Also, what's your DRAM voltage set to?

Try to input the voltages for the RAM manually. For X58 you can go up to 1.65V if your RAM allows it (you can actually exceed 1.65, but Intel spec says that 1.65 is Max safe V).

You could also try reseating your RAM. Some X58 boards are quite finicky about RAM

Start > Run > msconfig
Boot tab > Advanced Options
Check "Maximum Memory" and hit the up arrow until it maxes out (hopefully will be at the correct value).
Might as well check "Number of Processors" and set that to the correct number while you're in there, too.
Also a good opportunity to see what garbage is running as Services or on Startup.
Reboot when finished.


Mine sometimes used to show my 4gb as only 3.2gb or so, but the above fix seems to have taken care of the issue permanently.

Some OCZ ram is low voltage...1.5v if I'm not mistaken.
(may not like 1.65v...raise at your own risk)

Sorry for the slow response guys. Weather is nasty here, shoveling breaks

My ram is set at 1.5v right now and I just tried that msconfig suggestion. I cranked it up the the max ram (listed the proper number) and rebooted. Upon reboot, I see that it says 6.00 GB is installed but now only 4.49GB (A number that has never been listed before) is usable. Also when I go back to msconfig, the memory box remains checked and the maximum ram is listed as 2048 MB which doesn't quite make sense

Edit: Removed check from msconfig memory and rebooted, allowed the max 6135 MB to be recognized and used again for now.

That may have been the other solution. It's all kind of a black box in there anyway... nobody knows what Windoze does with it.
