I though that PC5300 should be compatible with PC4200 anyway, while it turned out a big surprising "no".

Toshiba Laptop with 512M PC4200 (Samsung) - OEM
Added Kingston 1G PC4200 - no problem, 1.5G for half 1 yr

Buying KByte 1G PC5300 today, I thought to use both 1G PC4200 Kingston and 1G PC5300 KByte, but it is only recognized as 1G.

Following are what I experienced

1G PC5300 -> 1G
1G PC4200 + 1G PC5300 -> 1G
512M PC4200 + 1G PC5300 -> 1G

That's interesting.
