Why does one memory slot not read as much as the other?

I own a ecs 755-A2 motherboard, The max memory is 2 GIG.

It has 2 slots for 1 GIG respectively, I have the correct memory modules but the number 1 slot will lone detect 256 meg no matter what size is put surrounded by the slot. the #2 slot will read the correct capacity I own tried to change around the modules and nought seams to work. I am running 768 meg and it does run great, I be wanting 1 GIG in it near my 2.2 amd sempron CPU. Any Ideas please help.

Call the motherboard factory owner for an RMA. If you like to live terrifyingly try updating the BIOS.
It may be that you have an inbuilt graphics card. Some memory may be shared by the card, contained by which case this is mundane and leaves the rest of the memory for software use.
Hi BillyJack,



Check your M/B manual, conceivably your M/B do not accept indisputable DIMM configurations. I am talking something like Single/Double Bank/Side memory modules.



Some M/B manufacturers post a restriction on the type of modules and the mix of modules you can use on their M/B.



If your M/B accept the configuration of the modules you put in, your problem is most probably due any a faulty M/B or the CPU (AMD CPU carry their own memory controller in the CPU chip itself).
Sounds close to slot 1 is broken... even if the ram robber video be stealing a chunk out of slot 1's memory you'd expect slot 1 to report something other than 256Mb.



Your choices are...

. Live near it... buy a 1Gb stick for slot 2 and you get 1.25 Gb total RAM.

. Replace the mobo below warranty or by buying a new one.
