Does your motherboard support 8GB and does it recognize all DIMMs?

Yes. MB is Asus P7p55D-E LX and supports extra RAM

4 x DIMM, Max. 16GB, DDR3 2200(O.C.)/1600/1333/1066 MHz Non-ECC, Un-buffered Memory

Hi,

openSUSE is showing only 3.9GB of RAM whereas I have 8GB installed on the system. Sometimes FF takes upto 800MG which slows the browser. I have installed 64bit version which should show full RAM. It shows OK under Ubuntu.

Sysinfo:/

OS:  Linux 3.1.0-1.2-desktop x86_64

Try running the "-PAE" version of the kernel. Read the kernel notes as to why you should do that if you have more than 4G of memory.

Ummmmm... why would he want to run a 32-bit PAE kernel? He's already running a 64-bit kernel. You only need PAE on 32 bit kernels to get beyond the 4GB memory addressing limitation... this limitation (at 4GB) doesn't exist on 64 bit kernels.

C. I think 64bit kernel is required when you use applications which eats more 2 Gb of memory. I think using of pae kernel saves memory, because you run 32bit applications which require less memory than 64bit ones.

I remember that my system was detecting and using the all of 8GB ram. The last time I checked was when I wrote about Ubuntu. I found a screenshot from that time and it says 8GB (I remember I added more RAM so that I can test more distros from within VB.) http://www.muktware.com/sites/default/files/images/manual/ubuntu1110/system-... It's only recently I noticed only 4GB RAM. The only physical change that I made was added a CoolMaster FAN.

That gives idea where to look. Pull memory sticks out and back in.

Whenever you work something inside the computer and something fails, first thing is to check contacts and connectors by simply re-seat them (pull out completely and then push back in).

If that doesn't help pull memory sticks out and inspect visually contacts and sockets for dust, as it can happen that reseating pushed some dust in a socket.

Seems like MB is the culprit. I tried resetting RAM and CPU but no success then I removed 2 sticks leaving on 4GB on board but then the system detected only one. I tried one and failed to detect RAM from 2 slot. I don't know if its a hardware issue or BIOS. Should I RMA? I bought it in August? Fortunately I had another MB P7P55D-E and tried it detected full 8GB RAM.

Check the manual for your motherboard and check into which slots the RAM has to go to be fully recognised; also check whether the RAM used is matched pairs or unmatched singles (also if they have 16 chips onboard or more - eg, a mobo I am using will not accept sticks if they have more than 16 chips on board). I had a Gigabyte motherboard which accepted 2GB of RAM, and had 4 slots for the RAM. At the time I bought 2X512MB matched DDRs and then later bought 2 single, unmatched 512MB sticks. The 2 matched sticks had to go into slots 1 and 3 to work as dual-channel RAM but when I added the single sticks nothing worked. Reason was that to get the full 2GB I had to have 4 single, unmatched, sticks. I didn't know this until I read the manual :-( .

Yes, the RAMs were working fine. I was using the full 8GB of it, but something went wrong lately.

Swapnil I fairly recently had reason to pull a memory stick (to find out what its type was) and I put it back-- unknowingly, it was not seated properly, and I theorized later that one of the pins was touching a jack connection that it shouldn't have. The memory stick got hot as blazes, and that slot on

It was an expensive lesson: do not work in dim light, and make _sure_ the memory stick is seated properly.

It was an hardware issue. The DIMM slots were not working. Swapnil

x86_64 obviates -pae Verify the motherboard/bios actually sees more than 4G. Sounds like a hardware/firmware compatibility thing not a linux kernel thing. -- bkw -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
