|"my motherboard is RC410 "|
You have an "OEM only" ECS mboard model. It was supplied to a brand name system builder by ECS, but it is not a retail model and there is no info about the model on the ECS web site, and Kingston has no listing for the mboard model.
It's probably this one - it can be in other brand name systems other than HP's, e.g. it's also used in Gateway systems.
Motherboard Specifications, RC410-M (Asterope3)
Memory upgrade information
•Single-channel memory architecture
•2 x 240-pin DIMM sockets support unbuffered non-ECC 400/533 MHZ DDR2 memory modules
•Maximum HP/Compaq approved memory is 2 GB
You can install ram that is faster than 533mhz, if the module is otherwise compatible with the mboard, but according to that info, your mboard can only run it at a max of 533mhz.
Ram that works in another mboard , or any ram you buy or have lying around, may not work properly, or sometimes, not at all - even if it physically fits and is the right overall type (e.g. SDram, DDR, DDR2, etc.; PCxxxx, xxx mhz) for your mboard. In the worst cases of incompatibilty your mboard WILL NOT BOOT all the way with it installed, and the mboard may not even beep - the ram has to be compatible with the mboard's main chipset, or in the case of recent mboards, compatible with the memory controller built into the cpu.
See response 5 in this for some info about ram compatibilty, and some places where you can find out what will work in your mboard for sure:
Correction to that:
In your case, you use the make and model of the brand name system the RC410-M mboard was in to look up which ram is listed for it.
However, Kingston often lists brand name system specific module part numbers for the ram, not the part numbers for modules it would find if you had used a retail mboard model to search with.
(On the other hand, most web sites where you can look up the ram that will work in your mboard, e.g. the Crucial web site, do not list brand name system specific module part numbers.)
""Does your computer's bios Setup recognize that 2gb of ram is installed ?""
"where i can find my memory info in the bios setup?"
You have a brand name system bios version on the mboard. Usually we cannot find information about what is seen in a brand name system bios version, so I don't know.
"edit: i found it, it also says i have 896mb ram"
The bios is detecting only 1gb of ram - 1,024mb - and is presently subtracting 128mb from that for the amount of ram that is being shared with the onboard video.
Usually the amount .that is being shared with the onboard video can be changed by the user in the bios Setup somewhere. It should never be set to more than half of the total amount of ram installed, and the lower you can set that and still have video performasnce that is acceptable to you, the more ram Windows itself can use.
""If the other module is not a Kingston module but is a brand name module""
"i dont sure if its brand or generic. i guess its a generic".
Brand name ram has it's brand on the label on the module, but sometimes that label may have fallen off over time.
CPU-Z may show whether that module is generic or not.
