8KNXP Rev2 PAT Function

Archived from groups: alt.comp.periphs.mainboard.gigabyte (More info?)

Have been experimenting with BIOS settings and Memtest 1.15. I've
discovered that BIOSs prior to rev FH do not enable PAT. If you're
running a gigabit lan it looks like the update to FH is for you. If
you haven't already tried it, the latest incarnation of Memtest adds a
couple of features including ID'ing ECC RAM and PAT state.

How do you check if PAT is enabled..

I don't see it. Where should I look?

Mine either.

Its under the memory option called Performance Mode

Are we referring to the same MoBo and how are you reading the PAT mode..?


Its a well know fact and the Asus MoBo has a patched Bios to get around this
limitation..

I read another article (on Tom's Hardware) that said to enable PAT on
Gigabyte boards, you have to enable M.I.B. (Memory Intelligent
Booster) in the BIOS. I did that, but CPUID still says Performance
mode - disabled. In reference to above, it also says my cpu (3.0 GHz)
is running at 3014.6 MHz on a bus of 201. I have everything set to
Auto. Since this is >10 MHz, could it be disabled for this reason?
Should I try setting the bus manually to get down to 3.0? Would this
enable PAT and would it be worth the bother?

Thanks,
Jim

Sorry. The 8knxp uses the 875p chipset and should have PAT turned on
by default. My board uses the 865p chipset, but is a Gigabyte board.
It has the M.I.B setting in the BIOS I was talking about. This is
supposed to enable PAT, but according to CPU_ID, it doesn't. It must
be some proprietary form of PAT that Gigabyte uses. I did slow my cpu
down to check the >10 MHz question refered to earlier in this thread -
no difference.

Nope. It is off with the BIOS setup defaults.

I posted this two weeks ago:

"After many reboots and experiments in setting combinations of PSB
Parking, Delayed Transaction, Command per Clock, and Fast Chip Select,
I think I've discovered when PAT is enabled. It looks like it
requires that CPC and FCS simultaneously enabled to enable PAT.
That's the good news. The bad news is that with PAT enabled the
system becomes rather unstable. In less than a day of running with it
enabled, Exact Audio Copy and Dantz Retrospect have both caused hard
and repeatable crashes. My advice to any potential users of PAT is
tread carefully. Backup your system prior to enabling it, and then
thoroughly test all your applications, especially those that use
optical drives.

Also, the state of PSB Parking and DelTran don't seem to have anything
to do with whether PAT is active or not. My system is now set for PSB
and DelTr enabled, CPC and FCS disabled. BTW, DPM doesn't seem to do
anything under any conditions."

Someone else said something about memory timing. PAT enabled/disabled
had no effect on the memory timings on my 8KNXP/V2
