Perf. accel. Tech (PAT) is it on ?

[scott]

I was running Memory Bandwidth in Sandra and noticed in the specs that it had a red X in front of PAT. While my scores are not bad they are not up to the first referance. ( which is what I have ) Also this is an unknown brand of Ram "House Special"= good price. So I was trying to figure out if it was on or off or weather or not Sandra reports it. And I found this Intel prog. that says its "Activated" I will attach some screenies and let you have a look.

What do you think ??

first Sandra

And then Intel

When PAT is enabled on my IC7-MAX3, Sandra reports it as enabled (ignore the ****ty memory scores... I've got loads of programs running in the background and this is with my old XMS3700). :)

In your case, can you not go into the BIOS and try enabling/disabling PAT (if you have the option to)?

Not sure on those Intel desktop boards...

Ther is nothing in the Bios.

Well... your RAM, rated @ 2.5-3-3-6, at 74% efficiency of 6.4 GB/sec puts you at 4,736 MB/sec buffered, which seems right on the money for a DDR400, Dual-Channel system that is not overclocked.

Seems like you are right on the money, but I would venture a guess and say PAT is not enabled.

PAT at it's highest benefit will give you up to an extra 4% increase in performance over a system without PAT increased, so it's not really that much. :)
