Regarding high-amp AMD X2s / FXs and some MBs unable to handle them

[imported_Kiwi]

I have a new AMD X2 6000+, AM2, 125 watt CPU, and an Abit KN9 SLI (nForce 570) MB, that I currently have an X2 4200 intalled in. Several recently produced MBs were reported to have had troubles handling high current draw CPUs -- have there been any similar complaints about "older" chipset MBs with similar limitations? I'd like to upgrade the PC that the Abit MB is in . . however, that Abit MB is now out of production, and Abit's support info on it is somewhat reduced now.

my much derided ecs k8m890m-m handles the 6000 just fine... even oc's it to 3.2...

Although I seldom pay attention to anything from ECS, it is based more on very poor end user support rather than poor quality. Is your ECS from the nF500 chipset series?

what do you need to know?
the 6000+ is supported http://www.abit.com.tw/cpu-sup...sli_an9-32x_series.htm

I also have an Asus M2N32 SLI Deluxe with the 590 chipset, and I had checked it for the 6000, but the X2 5200 that's in it now seems satisfactory.

The MB I have from Abit has the nF570 chipset, not the 590, and I looked around at Abit, found the same reference that you did (though not another for my own MB), and I just wasn't quite ready to automatically equate the 570 to the 590 about something that could literally destroy a working mainboard.

You don't have an AN9 then but a KN9 SLI. http://www.abit.com.tw/cpu-sup...orce570sli_kn9-sli.htm
can't really blame abit if you don't know which mobo that you have. :evil:

This was not a chipset problem, but an issue with the power circuitry on some motherboards. Boards with fewer power phases were having problems with the higher-power Athlon 64 X2s.

It was an Anandtech article, but I'm afraid I can't find it at the moment.

straight from the manual:

"...incorporates a k8m890 northbrodge..."

the famous via northbrodge...

really was the 125W Phenoms on 780Gs.

You only need to worry about Micro ATX boards (or smaller form factors) being able to support the upper-most TDP parts. The VRM limits you are referring to rarely apply to ATX boards. And virtually guaranteed to never involve an enthusiast ATX board.

Thanks. It's been getting harder to remember details from recently-reviewed articles. Some people refer to it as "Old Timers Disease"!

Same for swapping the first letter in the MB name, though I definitely had the "570 Chipset" parenthetical there all along.

This is exactly the problem I read about also, and was not limited to one particular chipset or motherboard manufacturer- it had to do with the power circuitry.
