Try Crucial's memory scanner for a guide of what RAM you can install and in what configuration: Use the Crucial System Scanner software to find out what type of memory is in your computer
I think I would look at the actual part number on one stick of that RAM and look it up to see what size it actually is. CPUz "should" tell you too, but if the BIOS is reporting it wrong CPUz may read it wrong too. If it is what the seller said it was, then it could be that its just not compatible with your motherboard. Some RAM modules just don't work with some motherboards, even if that size is supported.
On the stick of ram there should be a sticker that lists the voltage and timings. Try going into bios and making sure the ram voltage and timings are the same as listed on the stick. If you still have problems, I would think alphanumeric is correct.
From what I can find this is made by Adata. The 4 is the CL (Cas Latency) and the 512MX8 means it is 512Mb built with 8 memory chips. So you supplier is wrong.

Don't overlook the possibility that the wrong label has been applied to the module(s). Both the BIOS and CPUID (and other similar software) get the information about the modules directly from the SPD chip.
His sticker says 512MX8 and shows as 512Mb in his system so the label is correct. His supplier is wrong.

Thanks again for the replies folks.
I've spoken to the shop who said I can change it on Monday. Also found a qualified vendor list for my motherboard on the asus site so I'll probably take a print of that along and try to get one of the brands listed.
