Abit - KT7A and 1.4 multiplier problem - FIXED!!

[]^X^[]

The problem IS ACPI!! In order to get higher then 10.5x multiplier you need to turn off ACPI in the bios, remove all drivers. (booting into safe mode) And flash the latest ZT1.11+ bios. This will give you a new option "Disable/Enable ACPI" disable it and your set. :) I'm running 1.57Ghz right now at 1.80v. Going to try higher soon. Anyway I'm happy now, hope I'm helping someone with this post.

NOTE: when flashing the bios make sure you do not use the supplied runme.bat file. As it will not work correctly. Use the following syntax: awdflash biosname.awd /cc

PS. I'm running a 230watt psu, and crappy ram. Upgrading the ram monday, and looking for a good 400+watt psu. If anyone has suggestions please let me know. :) For all those that suggested the bios thanks guys!!

for a good psu, antec, enermax, and pc power and cooling are favorites here. Really any amd approved psu should be fine though.

Talk about the little power supply that could - LOL :-D
230W running a 1.57gig at 1.8V - now that's impressive! Hope you can get even higher with the new psu, 400W ought to be more than enough.

I find this very interesting. Is it because ZT 1.11+ does not inplement ACPI correctly? I ask because I am running YH with ACPI and quite frankly, I like ACPI enabled. That doesn't mean ole Hoot can't learn a few new tricks though.
If anyone has a link to a credible explanation, I sure would appreciate reading it. TIA

ACPI does seem to be the problem. Once windows loads and acpi kicks in it locks hard. The ZT1.11+ driver has the option to turn off acpi. This fixed my problems 100%.

I had the problem of mine locking up at windows to. Mine wouldn't even run 1.4. So I disabled ACPI (using ZT+1.11) and mine would manage not to lock up at windows start. Then I ran some benchmarks and it will lock up in 3dMark 2001 about 3 or 4 test into the benchmark, so I'm back @ 10x133 which runs the benchmark and doesn't lock up. I just wonder if my 40.0 amps my pwr supply provides is borderline on what the cpu needs to run 1.4.

[Hoot]

That Antec 400W supply can run your CPU just fine. It must be something else.

Well it's been a few days and it's still 100% stable. So this DID fix my problem. I have a new 430watt enermax on the way. :)

[bdf24]

Good choice! Thats what I got and seems to be real nice. Even while running an 85w tec along with the rest of the system kept my voltages all with in spec.

The Energmax430 is sweet but I still think the Antec with a nice case for a few extra bucks is a nice deal! Why does windows even need to mess with the CPU multiplier?? M$ is bloatware!

[asmodean]

It's just the ACPI stuff messing... M$ prolly doesn't know there are multipliers.

[Hoot]

You people are blaming the wrong end of the horse. I'd be grilling Abit who will probably blame VIA about this whole issue, since the problem varies from one lot of motherboards to the next. That is only my honest opinion.

I concur. I believe Abit to be at fault here as other motherboards seem to overclock 1.4s just fine. For my next system I'm going with IWill. :)

Where can I get this bios? on ABits web site all I find is a ZT bios not a ZT 1.11+ bios. If someone would be kind enough to email it to me that would be great.

When I flashed my bios I used the command line from the KT7A manual, And changed the name of the .bin file in teh command...It worked fast and apperently safer as it automaticly resets the bios even though the manual says to rest manualy anyway. I have one little idea though about the KT7A, Could it be that athlons on the KT7A are more senseitive to heat than when they are on other boards? All I know is that mine is a little too senseitive compared to what I have seen on other boards. I mean this is just a thought..maybe we should compare temps on other borads with the KT7A?

[mEKbOY]

The motherboard is not to blame as a i have an iwill kk266 and i have the same freaking problem so that messes all that up
