LCuK Posted December 10, 2006 Posted December 10, 2006 Hey chaps, I have oc'ed my sempron 2600+ 1.6ghz to 2.5ghz... Everything is working fine apart from the fact my (cheapy) ram is showing as 512meg and i have 1gig. Both are working fine when i put one stick at a time, it says 512 under windows task manager and system boots fine. When i put both in it still says 512 even tho cpu-z says i have 1024. The only difference between the two rams is the CAS timing... one is 2.5 and one is 3. I tried changing the bios to use CAS 3 but it still shows only 512. I changed the slots they are in but nothing happens. The wierd thing is when i have the CAS 2.5 one in my oc goes from 2.5 to 2.6ghz :s any ideas?!?! cheers for any help. http://img98.imageshack.us/my.php?image=512xx7.jpg Share this post Link to post Share on other sites More sharing options...
red930 Posted December 10, 2006 Posted December 10, 2006 after you make a sig:D do a cmos clear put the cas 3 stick in slot one. go into the bios and set the first 4 memory settings(3-4-8-4) then reboot. then turn off PC and put the secont stick in slot 3 and run memtest and see if it show 1024 memory and make sure you pass test 5 & 8 Share this post Link to post Share on other sites More sharing options...
LCuK Posted December 10, 2006 Posted December 10, 2006 Sorry mate it was about 4am when i did that post, too tired to do a sig I tried what you said but memtest keeps saying i have just 512 I got the latest bios from the main dfi site, it was dated 2005 i think. Is there a newer one? The ram i am using corsair Valueselect VS512MB400C3 for the CAS3 and VS512MB400 for the CAS2.5. Btw i havnt updated the chipset drivers yet but that shouldnt make a difference? because ramtest dosnt even get the chance to load chipset drivers? cheers for help pal Share this post Link to post Share on other sites More sharing options...

Maarek_Stele Posted December 10, 2006 Posted December 10, 2006 Sorry for not helping with this post, but you are the first person around that I've seen successfully running a x1600 with this board. Share this post Link to post Share on other sites More sharing options...

Really?!?! they been a pain in the butt? I didnt have a single problem with mine but having 512 of system ram isnt much good. Share this post Link to post Share on other sites More sharing options...
Guest Blooz1 Posted December 10, 2006 Posted December 10, 2006 Have you tried running Memtest on each stick individually? (Just noticed your x1600 - yes, quite a few people have had bad luck in trying to get an x1600 to run in this board - myself included!)

Ah thats unlucky man, i think it seems the sapphire ones are the only ones that seem to work, lucky i payed a extra £5 for the sapphire because its the only one that gives thermal readings (i wonder if that has something to do with the problem everyone is having?!?). Ive done a memtest on both sticks, working fine :S Share this post Link to post Share on other sites More sharing options...
Clawhammer Posted December 11, 2006 Posted December 11, 2006 another fellow was having the same issue.i guess he was setting his AGP Aperture to like 512,upon putting it back to 128 the problem was fixed.i personally think if cpuz recognizes all your ram and your computer "feels" faster everything is good to go regardless of what windows or the bios displays.

red930 Posted December 11, 2006 Posted December 11, 2006 put your memory in slots 2 & 4 or orange slots Edit sorry my bad slots 1 & 3 then make sure you give that corsair 2.75 v these boards are bullet proof BUT they don't like auto settings Share this post Link to post Share on other sites More sharing options...
