Hello guys..... I'm from Greece and I have an issue with my M/B

My PC:

CPU Intel i7 930
M/B Gigabyte GA-X58A-UD7 with BIOS F6
RAM 6GB OCZ Blade 2133 DDR3 (OCZ3B2133C9LV6GK) 3x2GB (DDR3_1 + DDR3_3 + DDR3_5)
Ge-Force 7950 GX2
HDD 150GB WD Raptor 10000RPM (boot)
HDD 400GB WD (data)
PSU Corsair CMPSU-850HXEU PSU (850W)

Here's the issue....

When I start my PC BIOS sees 2GB of RAM. I entered BIOS to change RAM voltage from default 1.50V to 1.64V. After that it can see 6GB of my RAM at 1066MHz. Next day I start my PC again and it sees AGAIN 2GB of RAM... I enter again to BIOS and sees only DDR3_3 slot. After NOT changing anything at BIOS, I save and exit BIOS and it sees 6GB of RAM.

It's my 2nd M/B. My 1st changed because it was broken from factory....


Thanx in advance guys..............

ps: no overclocking yet....
ps2: sorry for my English :p

Hmm. Try going to Start, and type in the search box, 'msconfig', go to the 'Boot' tab, and then in the tab, go into 'Advanced Options', and check the 'Maximum Memory' box and type in 6144, which should be 6GB. Then select OK, and apply, and then OK again. After this, you should be fine, although sometimes it is a different problem.

Lots of EVGA X58 3-Way SLI Classified motherboards tend to have this problem, and so does the EVGA X58 SLI LE - I personally did not experience any issues with my board, but many users have reported to only be able to use 3.99GB out of 6, but it seems you can only use two.

P.S. Your English is fine... :)

Lmeow thanx for the reply...


But if BIOS recognize 6GB, there is no problem on windows. So my issues are M/B, BIOS and RAM..... Maybe not all of them (hope so). People I asked about my problem told me to check another PSU or another RAM or another M/B.....

Thanx again man....

Are you using the correct RAM slots? That would be the white slots on your motherboard. Did you manually set the RAM speed and timings at the same time you set the voltage?
