No, the 533 MHZ is not the voltage for your RAM. Do you have a friend or associate who has tech knowledge? My first hunch is the memory voltage is not set correctly by the motherboard. But in order to know what is correct wqe need to find your exact RAM and see what the manufacture has set it at and then in the BIOS we can set it correctly (if need be).
My second hunch is corrupted memory as per your minidumps. It would be good for you to run Memtest on your RAM. This is a free and completely safe proceedure.
See the link below and follow the instructions. There is a newer version than what is listed but either one should work. If you need to see what the Memtest screen looks like go to reply #21. The third screen is the Memtest screen.
Let it run for a
LONG time. The rule is a
minimum of 7 Passes; the more Passes after 7 so much the better. There are 8 individual tests
per Pass. Many people will start this test before going to bed and check it the next day.
If you have errors you have corrupted memory and it needs to be replaced.
Also, with errors you need to run this test per stick of RAM. Take out one and run the test. Then take that one out and put the other in and run the test. If you start getting errors before 7 Passes you know that stick is corrupted and you don’t need to run the test any further on that stick.

* Get back to us with the results.
My third hunch is that this is the wrong RAM for this motherboard.
*** If you don't want to go through the hassle at this point take back your PC to that shop, tell them of your BOSDs, that your minidump files were read and many specifically stated that the cause was memory corruption. If they want to know the error codes give them 0x8E, 0x50, and 0x24.
