Memory Problems FRV37 Hello, i'm having a dreadfull time with this computer. My Sony Vaio FRV37, is unstable with both DIMMS installed, but solid with only one. Both are exactly the same DDR PC2700 DIMMS. but with one in, the system is stable, put both in, and i get random Blue Screen, IRQ crashes, after heavy loads. ive swapped the modules to see if any one Moduleis faulty, and the system is very stable with either of the modules installed, just not with both. I'm guessing the secondary slot is faulty, but i cannot install a memory module in that slot alone as the computer will not operate with memory in the "B" slot alone. or should it? Other than the memory being PC2700 instead of 2100, it is correct for this model. Is this a serviceable problem, or do i need to replace the entire motherboard? thanks for your imput

but the memory is exactly the SAME.
and each Memory DIMM is good because each will work by it's self in SLOT A. just not together.

If i use EATHER ONE of the DIMMS in Slot A, computer is stable,
But unstable if i put two in (Slor A&B) and it's not instantly unstable either. It takes awhile, before it crashes, normally after a heavy load/use. but the memory is exactly the SAME. and each Memory DIMM is good because each will work by it's self in SLOT A. just not together.

You model Sony supports a total max. of 1Gb DDR SDRAM (ie. two 512Mb RAM modules). Is the total RAM you are installing greater than 1Gb, this maybe the problem. If both RAM modules are 512Mb then you could have a fault in memory slot B. The specified RAM speed for your model laptop is 266MHz (PC2100), you can use 333Mhz (PC2700) RAM modules but it will run at the slower speed and should not affect the laptop. Since your laptop can support only 1Gb RAM and slot B is faulty, then you maybe able to put 1Gb RAM module in slot A. Take it to your friendly computer to try this out, if it work then swap and buy the 1Gb RAM module. You model Sony supports a total max. of 1Gb DDR SDRAM (ie. two 512Mb RAM modules).
