HI ALL. I'm new here.

Basically, I have 6gb of OCZ GOLD DDR3. In bios, 6gb is shown. CPU-Z shows 6gb and so does system info. But....that's only 6gb of installed memory. Only 4gb of phyical memory is being used.

Task manager shows 4096gb of phyical ram. sometimes it even drops to 2...but then i restart and its 4 again. I have switched slots and reset bios to default, but still not using 6gb.

here are my specs. What is the problem?

Core i7 920 with TRUE 120
EVGA x58 Motherboard
6gb OCZ Gold (1600, 8-8-8-24)
Antec Signature 850w
2x GTX 260's SLI
Creative X-Fi Fata1ity
Western Digital VelociRaptor 300gb & WD 1TB 7.2k RPM
Antec 1200
Windows Vista Ultimate 64

....soo.....i know people that are using evga x58 with 6gb of ram. almost everyone....

uh what should i do

its 4gb.
February 11, 2009 9:37:52 AM

total phyical memory is 4086 mb
February 11, 2009 9:49:40 AM

I dno, thats weird. Ultimate 64 bit SHOULD be able to address over 16GB of memory, right?

Could be a faulty stick of memory or more likely a BIOS issue with the RAM you have. Check for an updated BIOS as a lot of the manufacturers have been releasing RAM compatability patches like they're going out of fashion!

...what worries me is that fact it "sometimes is only 2GB". I'd run memtest in the meantime, and make sure voltages are set right.
February 12, 2009 5:39:56 PM

k il try that but anyone ever see this same problem before?

February 26, 2009 1:38:11 AM

uhhh
February 26, 2009 1:38:41 AM

i ran memtest, nothing wrong.
February 26, 2009 8:29:39 PM

any help? its using 2gb right now
February 27, 2009 7:59:38 PM

Just a quick question. As you're on an X58 board I'm assuming you have 6 slots and a 3 dim kit. Do you have DIMMs in each of the channel 1 slots which would be the 2nd, 4th and 6th slots (A1,B1,C1) or something similar? If you have DIMMs in slats 1,2 and 3 you're probably only going to see 4GB. As for why you memory is appearing and disappearing I have no clue. Could be you have just messed with the BIOS too much and it's gone skitso

i havent messed with bios much at all tbh.

i have them in the correct slots.

I have the same problem. 6gb of 1333 DDR3 in an ASUS P6T Deluxe. Bios and Windows ultimate 64 only shows 4 gb, but CPU-Z shows all 6gb. What's going on????
March 7, 2009 12:01:08 PM

this is so weird..idk
June 27, 2009 1:39:24 AM

Anyone find a solution to this? I've read to enable memory remapping in BIOS, but the X58i from XFX doesnt have that option and im having the same problem. Thanks for any help...

Anyone have a solution.. same problem here!

Sounds like a faulty mobo or ram module - "sometimes it's only 2GB..."


I would troubleshoot with that in mind (move DIMMS around, try a different set of modules, etc...), and contact the manufacturer ASAP adn work with their tech support: Both to help with troubleshooting and to cover yourself in case you have to RMA.
March 11, 2010 7:24:40 PM

Your motherboard can not ran your memory at 1600mhz at the timing or voltage you're using currently stablely... Trying using uping ram voltage (1.66V) yourself instead of leaving it on auto or using 9-9-9-24 and see if you can see all your 6gig of ram...

PEOPLE AND ALL PEOPLE HAVING PROBLEMS WITH RAM POSTING & RUNNING WITH LESS THAN SPECIFIED CAPACITY!!!

This is a Genuine FIX, please DO NOT RETURN YOUR BELOVED RAM, as I was about to do. Please do not take this with a grain of salt, this will guarantee that your ram will be back to its original capacity. Please post THIS FIX to all the PEOPLE who are having this exact same problem with different ram & motherboards of the TRIPLE CHANNEL X58 variants.

I have discovered luckily through thorough process of elimination that (keep in mind that I am not a techy, just very good with hardware... being that I can always source out the problem), when there is minute alterations to physical hardware while your PSU (voltage source is connected to your motherboard that the chipset or CPU's memory controller enters a SAFETY state or locks out certain physical hardware from damage, as personally I have discovered as I have a dual PSU setup with exactly 1000Watts. I had unplugged my 400watt PSU to try and fix my power led connector as the light wasn't on after I tried a ridiculous overclock attemp. Now to my understanding intel has hard coded a fail safe in the hardware (chipset or CPU) that when there is a very minute voltage fluctuation in voltage sensitive devices, I'm pretty certain that the QPI is the most vulnerable and sensitive part when it comes to voltages, as it communicates with the CPU at high bandwidth much like cache & at the same kind of voltage as the CPU (QPI is roughly 1.2volts = very small and sensitive voltage).

NOW HERE IS THE FIX!!! DON"T RMA YOUR RAM!!!

You have to physically reset your system to re-instate your memory capacity, this is how it works... I'll put it in step form.

STEP 1. Shut down & Power off your PC, physically at the PSU Power switch, or in my case switches.

STEP 2. Remove all memory modules to discontinue any voltage source to QPI.

STEP 3. Reset CMOS & reinstall modules.

* In my case I had problems with both my inner & outside DIMM slots as they weren't working & only the inner slot worked (2gb of 6gb that I had was only running), so I tried to reset everything & just put one module in the first white DIMM slot (i have a Gigabyte X58-UD3R) & wallah she was working again!

STEP 4. Put all modules back in & then power on the PSU.

STEP 5. Power on your PC & jump into your BIOS & check your memory capacity.

*To prevent memory reverting to reduced (2gb for your 6gb tri channel or 4gb of 12gb tri channel) you have to make certain that there are no physical voltage fluctuations, if by removing connected PCI Express connectors while the PSU is still on or trying some ridiculous overclock attemp. So please keep this in mind if you don't want to loose your precious overclock settings or to prevent any damage to your system.


*REMEMBER, DISCONTINUE ALL VOLTAGE SOURCES BY TURNING OFF YOUR PSU BEFORE MAKING ANY HARDWARE ALTERATIONS
