It's not a simple topic. I can tell you that PAT is enabled on my IC7 at
either 1:1 or 5:4. I can still tweak memory settings and overclock to the
limits of my ram with PAT enabled.

When I went from two to four sticks of ram, PAT was disabled at 5:4 but
worked at 1:1 or when the NB strap was set from 800 to 667 -- which limited
fsb overclocking and lowered performance. The Abit released a new bios
update that got all the performance back -- even improved it at 5:4 --
though PAT still reads disabled. The 5850+ Sandra memory scores I'm getting
at 5:4 now are right up there with the PC4000 1:1 scores I see with PAT
enabled. That leads me to believe it's actually working, but just not
registering in the apps that normally pick up on it -- like CPU-Z or Sandra.

And if you think that's confusing, try to figure out what GAT does, or how
to get it working at anything other than the default AUTO settings.
According to an FAQ at Mushkin, setting GAT at anything other than AUTO
overrides both the SPD and manual timings and runs the memory at 1:1 at
settings that equate to 2,2,2,5 in F1 -- faster than most memory will run
comfortably. I've never had any luck at all with it, any setting I select
either makes the system less stable or shows no measureable improvement.

The hassles with getting GAT configured are one of the main reasons I
plunked down an extra $20 for a Canterwood board. After reading some of the
laments from those trying to emulate the results from the review sites on
Springdale boards using GAT, I'm glad I did.

In general, the Canterwoods clock higher and don't have to resort to tricks
to get good memory performance. Why settle for a simulation when the real
deal doesn't cost much more?

Hi,
just trying to get some *confirmation* about this tech. I understand that
it is meant to be a bonus feature of the Canterwood chipset that somehow
makes the memory work faster. What I wont to know now is whether this
feature only works when you run your FSB and memory bus *synchronously* as
in 1:1.

I seem to be reading stuff that says it is not available when you run say
in
5:4 ratio?

If this is the case then its a great *leveller* between Springdale and
Canterwood chipsets, where someone wants to run 5:4 ratios. . .Is this
true,
or am I misinformed?


I am reading about G.A.T now, an ABIT feature similar to PAT for
Springdale
chipsets. .

Looks cool, and seems to be getting great results in web reviews (lol
Streetracer, F1, sound funny)
