Just curious as to the most modern CPU that supports this RAM...

What's the most modern generation of CPUs that support DDR PC3200 memory (without being bottlenecked)? I'm just curious.

I'm guessing an Athlon 64 era CPU?

without being a bottleneck I'm not sure, but you can use a Core 2 Quad with DDR1 if you want.
but I think dual channel DDR1 400 wouldn't be to bad for some Core 2 Duos

How about a Cedar Mill P4? Remember: I want ZERO bottlenecks due to the memory speed.

Athlon XP...

P4 can work with DDR2 and will gain a little, the same for Athlon 64.

Well you are being silly if you want to stipulate "ZERO bottlenecks" given that all memory by default bottlenecks the processor to some non-zero degree...that is why processors have on-die cache (to minimize the non-zero bottlenecking imposed by the ram, but it only minimizes the bottlenecking, doesn't eliminate it).

True enough. What I meant to say was someone knowledgeable (such as yourself) won't look at the system and go "Why the heck is that X processor paired with DDR400 RAM? That's ridiculous."

So with that kept in mind, is a Pentium D "too fast" for the memory? You know way more than I do. I'm no computer engineer. I'm just considering a well-balanced system, relative to its own components.

Or how about a Pentium D 960? I think that's the best I can do, really.

this CPU would benefit from DDR2 memory compared to standard PC3200, the same as a Core 2 Duo E4300 or something I would think.

I don't see any huge bottleneck, using DDR 400 with the D 960 or a lower model Core 2 Duo...

but I think DDR400 is more adequate for Athlon XP, or single core p4 (northwood or Prescott with 200MHz fsb)

I guess to go with my original question (the way it was worded): what's the fastest CPU that literally will simply run on DDR400? I'm really curious more than anything.

Core 2 Quad (probably the QX6800, since the 775 MBs with Conroe + DDR1 support I've seen were limited to FSB 266)

but again, DDR400 was adequate for high end CPUs up until early 2006.

I have an old Opteron 165 @ 2.7ghz (Athlon 64 x2 with more cache basically) and it uses DDR400 in dusk channel. The A64's integrated memory controller allowed much lower latency access to ram, minimizing the need for faster memory. I'd say for gaming and most other "home" uses, DDR1 is fine for this chip.

What's with the bottleneck stipulation? A Core 2 rig on DDR1 would be bottlenecked relative to a native DDR2 platform, but it would still be a heckuva lot faster than an Athlon 64/X2 rig.

Why would you even consider spending money to "max out" DDR400? If it was CAS 2-2-2-5 memory, or DDR500, maybe I could see it.

Edit: Newegg is selling an ASrock 775 board that takes DDR400, last I checked. I think it even takes 45nm CPUs. Don't know about quad-cores.

might be a hobbiest thing?

I remember threads speculating on building the fastest AGP rig possible shortly after it had been phased out for PCI-e, so a query into a topic like this isn't too surprising to me.

Unless you're doing something incredibly memory intensive, you can probably use a Core 2 Duo, Athlon 64 X2, or even a Core 2 Quad without issue.
