Hello,

I think I will never stop fiddling with AGP in all its revisions, not sure why it fascinates me.

As I understood, when it come to raw performace, for AMD there is the AM2NF3-VSTA; for Intel we have various choices, from the dual series agp+pcie to the pure and legendary Conroe865PE.

Both routes use quad CPUs, probably Intel has advantage.

But both are seriously memory limited, worse for Intel with less than 4Gb (3.something).

In theory AM2NF3 could support 16Gb but in reality you need to stick with 32bit OS so again 4GB.
Now, to go for 8GB of RAM, there are also 939 and 940 sockets, sacrificing cpu performance for sure.

Is there any Intel counterpart that I am not aware of that can handle 8GB?
It would be super interesting to see if more ram would give more breath to the whole AGP system and push it a bit further.

Server memory (FB RAM) typically has twice the capacity of standard memory.
Some motherboards unofficially support such modules.
Although the 865 chipset will likely only work with 4GB of any memory type.

AliExpress also offers Chinese memory marked "AMD only."
Oddly enough, it's AMD-only—it has slightly different addressing.
There are also modules with unusual capacities.
The Phenom 2 definitely supports 32GB, although I tested it with DDR3.
Experiment if you like.

All those things are covered already.
My question is on Intel platform, if it exist.

The last Intel chipsets to support the AGP bus were the i865 and i875 series from 2003. They supported up to 4 GB of RAM, regardless of its type (ECC or non-ECC). As far as I know, no desktop or mobile chipset before 2005 supported more than 4 GB of RAM.
Considering server chipsets, Intel had the E7505, which supported up to 16 GB of memory and an AGP bus.

Yes,but it is about Netburst.
It is a greater drowback than 939/940

Ok,
I think my search can stop, no Intel route to be taken to have 8GB of ram and AGP with something newer than Netburst.

Guess I am stuck with AMD and an SK8V.
Judging from this video:

It seems that XP is the OS for gaming on old hardware (no surprises).
Same for XP64?
