hi.. i dont know if this is the appropriate place to ask but,,
recently i tried overclocking my ram @ 1900hz
and when i boot in the windows it only shows 2gb available ram. and sometimes 1gb.. while in cpuz it states that i have 3gb of ram available

i have 3 ram modules which are 1gbX3 ddr3

my specs

Asus P6T
Corsair Dominator 1X3GB 1600hz XMP PROFILE
Core i7 920

ahahaha im one of them previously,but not to say ram issue on the p6t but more to ram issue itself and to make it worse happen to my dominator cl8 before..slight voltage adjustment equal to lost of 1 0r 2 stick ram..

well my problem solve after getting new ram cl7 dominator actually, so i guess its the ram is the culprit since it can run on its designated speed of 1600mhz cl7 or cl 8 on 1.56v(my old cl8 stick) but if bump the voltage to higher you start seeing loss of ram..
or even overclock the ram hogher then 1600 equal the same..so i guess cl8 dominator 6 gb kit was not compatible to p6t coz my cl7 dominator 6gb kit perform flawlessly on the same board..

mine is also cl81x3gb dominator when bumping the voltage or ocing on stock voltage this happens

cause it might just happen again..

Just bought my brand new DFI DK x58 for RM690 only
I think P6T is RM850. Btw KVR 1333Mhz CL9 3GB also sometimes appeared as 1GB on my old P6T too.
It could be compatibility issues btween the mobo & RAM.

i just did some testing last night..

it seems there was some problem with the ram..

this is what i did

1st i oced the rams to 1800mhz

and then the usual problem it says only 2gb of ram available via bios..

next i tried to unplug one by one to see which one is making problem.. and hence i found one bad ram..

then i tested all the slots with the good ram just to see whether its a mobo or ram problem.. and there you go..

its a ram problem.. i think..

gonna test with memtest tomorrow

Last time I also swapped the rams between the slots to make it work.
no ram error though.

i really have no idea now.. last night i conducted a test again..

1804mhz @ 9-9-9-27-2N @ 1.66v
UCLK V @ 1.35
VCORE @ 1.28750
IOH n ICH @ 1.2

successful boot at 2gb only.. actual ram 1024MB*3

Test Passed
--------------
Memtest86+

superpi failed at 32mb loop 4..

the stability doesnt matter..

my curiosity is more towards the incorrect ram size shown

OS Windows 7 64bit..
