Only 4gb of 6gb is working???

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

refer to my last post

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

uh what should i do

look at TOTAL not available RAM

total phyical memory is 4086 mb

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!

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

i ran memtest, nothing wrong.

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 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????

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...
