845e / 845g / 850e - Is there any major difference?

[Dethedrus]

As the doubiously proud owner of a shiny new ABIT BD7II-R (845e), I'm worried that I just bought a potential lemon. Is the 845g's ability to "officially" support PC2700 really that major of a difference? Does it shift performance more than 5% or thereabouts?

And how much does PC1066 and a 850e boost it above that?

I guess what I'm getting it is will I see any humongous boost in the main app classes (productivity, games and 3D, all of which I spend a good amount of time using)

Thanks!

If you refer to the specs for the 845G chipset on Intel's web site you will find NO REFERENCE to any memory other than DDR200/266 (and PC133 sdram too). This fact seems to be of little concern to many of the motherboard manufacturers (my Epox 4G4A+ even has a DDR400 setting), and most of us in this forum.

Maybe they will update the spec, or release an "845G+", but officially, your PC2700 mem isn't supported.

No comments yet about the differences in performance. That question is a little lower on my testing prioity list than some other things.

sorry...to answer your original question:

Intel's official position about major differences
845--400mhz bus DDR200/266 or PC133 SDRAM
845E--400/533 mhz bus DDR200/266 or PC133 SDRAM, USB2
845G--400/533 mhz bus DDR200/266 (no SDRAM), USB2 and integrated graphics

Well, thus I said "officially" I'll grant you that this being an OEM addon is a bit troubling, but then again it's not as if I haven't taken advantage of unofficial FSB... I have very fond memories of my ASUS P2T4 (?) and 75/83 mhz FSB
