AMD HyperTransport & Compatible Memory Speeds

[MrDoomMaster]

I am interested in buying a AMD Athlon 64 4000+, and it appears to have an HT of 2000MHz, whatever that means. I used to get memory based on a simple FSB, but I don't know if it's that simple with this particular processor.

If someone could explain the math behind the HyperTransport frequency so that I could pick out RAM with a compatible DDR speed, I would greatly appreciate it. Thank you!

Does this help?

I would buy at least pc3200 and I would go with Corsair XMS, Kingston hyperX, Crucial ballistix or OCZ. Pc 3200 seems to be the standard for most systems, but you could go with a faster ram.

It also depends on the socket, as there is 939, and the newer 940 = AM2 socket, which brings DDR2 support to the table.

Thanks for the replies guys.

My biggest concern is being able to find all compatible types of memory for the processor. I have no way of confirming that PC3200 is even compatible with the processor in question, nor that it is the best compatible memory speed for the processor.

If something faster than PC3200 works with the processor, I would rather use that. Knowing the math behind HT would help in figuring this out.

As i said above, it depends on socket too, as AMD processors didn't support DDRII until the AM2 socket recently, so if you're going for a AM2 4000+ then you could get some DDRII 800 Dual Channel.

As HT shouldn't make a difference to memory choice. AM2 supports 3200 PC2, 4200 PC2, 5300 PC2, and 6400 PC2.

You won't go wrong with Corsair XMS 3200. The cpu has an onboard memory controller so you could use what you want in it for the most part. As long as you know rather it takes ddr 1 or ddr 2.

Scratch my last post(s), as the 4000+ only comes in socket 939, so you'll be stuck with DDR, 3200 would be the fastest, Dual Channel with a board that supports it.
