PC133 memory in Sony VAIO PCG-Z505LS? |
|
|
Someone gave me a 256M module to try. It was recognized by the BIOS
with 384M total (which would be correct), but Windows ME just kept
rebooting.
I know that Sony only supports up to 256M in this laptop but I've heard
others claiming 384M. Or, is it a bus speed or standard issue that
makes it either incompatible, or requires a change to the CMOS or BIOS
upgrade?
Thanks.

Most PC133 memory is 168 pin 32x4. I believe you need a 144 pin module
16x8. |

Or for 256mb, PC 133 is 64x4...when you need PC100 32x8.

Well, it fits physically and as I said, seems to pass power on boot
diagnostics.
Quite possible that the organization isn't compatible though.
Thanks.

So it must be a 144 pin module. Does it have eight chips (double sided)
or four?
I agree that it is interesting that the memory is recognized by the
BIOS. Did you try removing the existing 128MB module and replacing it
with the 256MB module? |

4 chips on each side.

Unfortunately, that requires almost total disassembly of the laptop since
it is on the *bottom* of the mainboard.

Ugh - I suppose the base memory may be soldered in, too, which would
make swapping it out completely impractical.
You can pick up a 128MB PC100 module for $35 plus $5 shipping if you
really feel you need the upgrade. I'll note that for most uses Windows
ME runs just fine on 128mb.

No, it's the same physical format and socketed but not worth the effort
to get to it.
I know. It's sort of a purity thing. I'd like it to be full. :)
This memory was already available.
Thanks.

Oh yeah, I know about the 'sense of completeness' feeling <grin>. |

Try slowing it (memory addressing) down a bit in BIOS and see if that |
works...or it 'could' be a bad stick. I've had memory test fine in POST,
which totally screwed up in operation. In any case, obtain and flash the
latest BIOS.
