What is the upper limit of SD card as GB without any freezing or slowrunning problem in Kodak easy share V1003?

You can only use SD (and MMC cards) up to 2GB in size.

No. You cannot use a 8GB SDHC card in the C360. The C360 supports MMC and SD cards up to 2GB in size.

The Z612 works with MMC and SD cards. While SDHC cards will fit into the slot, they are electronically incompatible and won't work. You need to stay with SD cards, 2GB and smaller.

The DX6440 uses SD cards. While SDHC cards will fit into the slot, they are electronically incompatible and won't work. You are limited to SD cards 2GB and smaller.

the bes choice is go to kodak website and download the manual or to see the carateristicas

Unfortunately. you don't. The Z612 works with SD cards, not SDHC cards. You're limited to cards 2GB and smaller.

The C330 uses SD and MMC cards. SD cards are limited to 2GB in size, so that's the upper limit. Cards bigger than 2GB are technically SDHC cards. They will fit into the slot but will not work.

Although the manual doesn't specifically say the maximum capacity, looking at their accessories website only sells 1 GB cards for the camera. This tells me that the maximum capacity is, indeed, 1 GB which is not an uncommon occurrence.

Which size has the memory card? More than 1GB?
The spec for the SD card format is going to 2GB but the Kodak C330 not compatible with 2 GB SD memory cards.
