Re: memory not recognized?

Take all ram out and put one in at a time to see if it reads each one of them.

W7 64 bit pro

These are the specs, but I don't see 64 Bits support. Hence it must be running 32 bit and Windows 32 Bit has a 3GB limitation. Furthermore, even if it did recognize it. Your applications must be written to utilize more RAM. For instance I have 16GB and never seen the usage go more 3GB.

Want to add ddr3 memory to my p5qc board

The motherboard supports DDR3 1333/1066/800 MHz or DDR2 memory 1066/800/667 MHz to meet the higher bandwidth requirements of the latest operation system, 3D graphics, multimedia, and Internet applications. The dual-channel DDR3/DDR2 architecture doubles the bandwidth of your system memory to boost system performance, eliminating bottlenecks with peak bandwidths of up to 19.2 GB/s.
DDR2 1066MHz DIMMs work only on the black slots for one DIMM per channel

RAM Slot does not recognize more than 512MB ( 184 )

Consider updating your motherboard bios.

Also make sure that your memory is correct for this system:

- Max. capacity of system memory: 2GB DDR or 2GB SDRAM
- DDR x 2, DDR266/200 non-ECC, un-buffered memory
- SDRAM x 2, PC133/100 non-ECC, un-buffered memory

My asus m3n78-em motherboard does not boots with 6 gb ddr2(3 chips of 2 gb) ram it works properly with 4 gb ram(2 chips of 2 gb) i dont know what to do it used to work properly before but its not working...

This board has a dual channel memory. To function correctly both channels must be identical otherwise , as you can witness, it chokes. To put it simply you must put either 2 identical sticks of memory or 4 - it can't run on 3.

I have an Acer Aspire 7540-1284 laptop that came with 3GB memory. The specs say expandable to 4GB but the manual says expandable to 8GB using soDimm modules. I can't find info anywhere to support...

it prolly has 2 ram slots, capable of holding a 4gig ram stick apiece- for a total of 8 gigs.

however, the largest ram stick they currently make is 2 gigs. your board can support 2x4gigs of ram (8 altogether), buit the most ram you can currently purchase is 2x2gigs (for 4 gigs altogether).

additionally, you have to have a 64 buit version of windows to regognize all 8 gigs if you had them.
a 32 bit version of windows will recognize no more than 4 gigs of ram.

ASUS P5VD2-MX SE recognizes only up to 2500MB RAM


Actually you are doing better than you think, According to your MB specs it is only supposed to hold a max of 2GB (1GB per slot). The updated BIOS may be allowing for the additional 500MB.

If you would like to verify, here is a link to the manual for your MB:

P5VD2-MX SE Manual

See page viii.

Thanks for using Fixya.

Asrock p4s61, tried 1gb pc3200 to max memory to 3gb, won't boot.

you quote one of your memory sticks as being pc 2700 when earlier in your text you qoute pc3200.

Firstly pc 3200 is 400 mhz clock speed memory.Secondly, pc 2700 is 333mhz clock speed and you acnnot mix the two on the same board. Thirdly does your board support 3ghz anyway. If you are running a board at 400mhz, pc2700 memory will not run at 400mhz.

Solution, take out the pc 2700 memory and all will be well.
