I was browsing for a RAM upgrade earlier for my system, and came across 'AMD-only' RAM (aka, RAM that only works on AMD chipsets). This RAM can easily be found on sites such as eBay, and seems to be slightly cheaper than 'normal' RAM.
The RAM prompts a question: is this RAM really restricted to AMD chipsets?
When considering RAM for a system, there are certain considerations to make such as:
- Speed (1066MHz, 1600MHz, etc);
- CAS (latency, lower is better);
- Generation (DDR2, DDR3, DDR4, etc)
However there is usually no such consideration as chipset compatibility. Sure, it's possible to guarantee that a given stick of memory will work if it's within the bounds of the chipsets listed in the information given by the seller/manufacturer.
For instance if a series of chipsets supported RAM between 1600MHz and 2400MHz, with 9-12 CAS, and on DDR3, it would be possible to list a product as being fully compatible with that series of chipsets if the said RAM was 2000MHz, 10 CAS, and DDR3.
I suspect that's partially the story here. However, is it possible at all for a given stick of memory to be 'AMD-only' or 'Intel-only', and if so, how?
