amd chipset specific ram?

[Quote16]

alright don't ask why i'm buying ddr2 lol my pc is a weird specimen 

 

but anyway i currently have 7gb ram in my pc (2+2+2+1) and i want to finally bridge that gap to 8gb for ocd reasons and i'm on ebay looking at what those sellers have to offer when it comes to a single stick of 2gb ddr2. i play  games very well right now so i don't need it immediately therefore i don't mind looking at the listings in china that'll take half a month to ship. i keep coming across things like this that have a disclaimer at the bottom that says "this will only work with amd chipsets will not support intel chipset" and i was wondering if that was actually a thing? i've looked it up but the tomshardware thread really never had anything solid so i came here. any answers?

RAM voltage seems really high, it might be that Intel boards don't support RAM on that high voltage. Couldn't tell you for sure though

googled a bit, other sticks of the same kind of memory also take 1.8 volts. My ram also used that amount. (DDR2 @ 667 mhz) So nothing strange there I gues. Must be the standard for that RAM era... Can't figure out why it should be AMD only...

Some intel chipsets don't like memory sticks with a lot of memory chips arranged in a particular way on the stick . AMD processors and chipsets were more flexible in that regard.

If you don't have an AMD system, it's best to avoid those memory sticks that are advertised to be for AMD systems.

 

1.8v is standard for DDR2 just like 1.5v is standard for DDR3.  In the past, manufacturers made memory sticks with voltage ratings of up to 2.1v for DDR2 (either because the technology wasn't that mature right the beginning or as a factory overclocking to sell sticks with higher frequency), just like we had DDR3 memory sticks with voltage rating up to 1.65v (from 1.5v which was standard)

I have some 1.8 volt ddr3

Yeah, there were memory sticks with voltage higher than 1.65v for DDR3 but they quickly went off the market when it was discovered that some Intel processors have a "bug" in the memory controller inside the processor which increases the risk of processor dying if the memory sticks are ran at higher than 1.65v.  AMD had no such problem.

That's why for a long time all memories were standardized at 1.65v and later when the big manufacturers got the fabrication process right, they managed to lower the voltages down to the official 1.5v and now with shrinking of manufacturing process they can sell 1.35v rated memory sticks (DDR3L).

ah alright. i wish there wasn't such a dramatic cost difference b/w sticks advertised for amd and sticks that seem to be universal. i was hoping not to spend more than $5 on something so small haha. well thanks all!
