messenger77 · Jun 22, 2010

messenger77 · Jun 22, 2010

Will do....tks, Muss

messenger77 · Jun 22, 2010

Already enabled it, still no change.... what to do.....?

So you have lost 78mb of ram huh? :laugh:

tbh I wouldn't worry I have seen Windows report like that or 2048mb or 2gb etc I dont really know why, though I wouldnt worry about it, 1.97gb is practically 2gb.

Try use cpu-z and see what it says :toast:

No, I think i lost 2 gb of RAM.... CPUZ shows 4gb but what I don't understand is that why did windows shows usable RAM at 1.97, does it shows the usable RAM of one stick each and WEI score doesn't improve since I instlalled it

post us a screen of advanced boot options (run msconfig, boot tab, then click advanced options)

also are you sure the 2nd memory stick is put onto the motherboard properly, and in the right slot?

Advanced boot shows only 2048 mb of RAM

IINexusII · Jun 22, 2010

are you able to set it to 4096? if not then obviously one of the sticks isnt in properly

No, it shows only 2048 I think I did it good coz, cpu-z shows it as 4gb........

Verify CPU socket pins are in good condition. Sometimes a bent pin will cause a channel not to show up.

messenger77 · Jun 22, 2010

BIOS at system default, update to most recent BIOS version.... :banghead:

I disable advance boot when using msconfig for myself as I kinda get the same issue what you have, when I enable it I get only 5gigs usable (6gigs installed :confused:

) crap:shadedshu so I don't bother with it

, if that doesn't help, check your RAM voltages too in the BIOS, put them at defaults or within voltage limit, I had my RAM automatically set at 1.7volts when I was overclocking which is a no go :cry:

and it showed up 4gigs RAM instead of the full 6gigs installed so set it back to 1.5volts which fixed it too, thanx to TPU :rockout:

this is just my experience bro, I hope this helps :toast:

I wasn't familiar with this so I looked. In my rig, none of those boxes are checked. I think what is happening is that you have locked the system into only recognizing the 2gig.

Try unchecking the box and rebooting.

messenger77 · Jun 22, 2010

Let me try it, thanks, bro...... :toast:

Bo$$ · Jun 22, 2010

also up the NB voltage 1-3 notches

messenger77 · Jun 22, 2010

Still no result.....I've put each RAM in the same color slots i.e blue, even manually adjusting the voltages......still not working..

messenger77 · Jun 22, 2010

No change whatsoever......

Athlon2K15 · Jun 22, 2010

imc voltage

mlee49 · Jun 22, 2010

Reseat the sticks, perhaps you have a bad stick or a bad ram slot?

messenger77 · Jun 22, 2010

Will go offline and check everything again... thanks everyone

Mussels · Jun 23, 2010

odd, normally these problems are solved by now
