my pc is god damn slow for 3gb RAM
so I bought 2x4gb PC3 DDR3 1333

I researched and dig some of the compatibility but once I've replaced my old RAM to the NEW one after windows logo it resets back.

I've tried - removing battery, removing the backup battery, holding the power button to 30 sec, and putting it back. but it doesn't work! i freakn hate this DELL for upgrade, they don't even have RAM settings in BIOS.

any help would do guys

specs:
OS windows 8.1 pro
Inspiron n5040
x64-base PC
Intel(R) Core(TM) i3 CPI M50 @2.27GHz, 2261 Mhz, 2 Core(s), 4 Logic

actually when I inserted the 2x4GB ram the bios detected my Memory but once I open up windows it doesn't work.

Right. Transcend memory module part number TS512MSK64V3H uses higher density memory chips. The Inspiron 15 N5040 CPU (i3-390M) seems to support lower density memory chips only. So the N5040 doesn't work with these (TS512MSK64V3H) Transcend modules due to their higher density memory chips.

A secondary issue may be that the two individual modules may not be (fully) compatible with each other (even though they are the same part number). This is due to variations in memory module characteristics which are unique to every module. In order for two (or more) modules to work together (to be compatible with each other), it requires that the module characteristics to be similar to each other.

If wanting 8 GB total memory for the Inspiron...

If wanting 8 GB total memory for the Inspiron 15 N5040, then it is recommended that a dual channel kit of 2 x 4 GB be used, as the modules within the kit are guaranteed to be compatible with each other. Trying to match individual modules (not from the same kit) can be time consuming and expensive, as it may take a few attempts with different modules (with same part number) to find a combination of modules that are compatible.

A list of some compatible memory modules to consider -

Corsair

Crucial

Transcend (& JetRAM)
