If you get the RAID version, be prepared for a lengthy brawl with Win2k. The general solution seems to be (and it worked for me) to ditch ACPI.

I have the board and it runs like a champ. Being able to crank the FSB up to 133 is a dynamite deal and had a big increase in performance for me.

Upgraded from KT7 with Duron 600 @ 935Mhz, to KT7A and Duron 750.
Motherboard was $127, CPU was $61, and bought a decent case w/PS for $26 as well, at microbarn.com.

Older KT7 600@935, 1.75v ran around 50C at idle, and 56 under heavy gaming load.
Max it would do is 935MHz, with best memory and cooling. Tried everything.
But it was rock solid stable. Remote for TV Tuner card would not work.

New KT7A. Duron 750 easily runs 1008MHz. 1.82v runs 36 idle, and goes to about 45 under heavy load. Again, rock solid stable, and remote now works with this "A" verion!

------------------------
EDIT:
After ton's of testing, I found the 133fsb speed useless for me.
Currently running 112/37 x9=1008MHz. AGP and IDE run at 75MHz.
Memory at HClk+PCICLK, or 149MHz.

Running 133/33 x7.5=998MHz. AGP and IDE run at 66MHz.
Memory is not given choice of HClk+PCIClk, and must run at 133MHz.

Also tried 140/35 x7=980MHz. No boot at x7.5 or 1050MHz.
AGP and IDE run at 70MHz. Memory stuck at 140MHz.

Benchmarks clearly show 112MHz x9 is fastest. The only thing 133MHz does is increase internal CPU speed, but slows down everything else. More is gained by increasing everything, not just internal CPU speed.

Just crank it up and see how far it goes, you should get 900 - 1050Mhz out of a Duron 700
I run my Duron 700 @ 933 (133FSB) or 950Mhz (143 host + PCI) at 1.775V

It will do 7.5 x 133 = 1000Mhz at 1.85v temps raise much quicker at that speed

Normally idling at 34-36 and peaking at 48-49C after heavy gaming sessions

Well, just the 133FSB alone took me from 6200ish in 3dmark2k to 7433. Sandra likewise bore out higher marks in the memory tests (519/541), but now I'm wondering about maybe shifting back down and trying for 1200(12@100) vice my current 1133(8.5@133) just to see if there's any major difference.

Hmmm....

Going to reboot and give it a whirl.

 

[grendelkhan]

Well, as Jesse Jackson would say: "The question is moot!"

My CPU won't even post anything above what I'm running now. Mega bummer.

Oh well, I'm still getting great performance out of this puppy so I'm not gonna bitch.

grendelkhan,
you need to do a little bit more tweaking with your board yet - on the memory front!

I'm getting 556/583

 

[gtd2000]

Here is an indication of my memory scores

133FSB:
fast/cas3 = 458/518
turbo/cas3= 522/571
fast/cas2 = 504/538
turbo/cas2= 556/583

 

[RobsTV]

Thanks for posting Sandra memory scores.
This helps prove my point that 133MHz is not always best.

My results with Duron 750 at 1008MHz, using 112x9.
525/615

Reason is simple.
133FSB = 133MHz memory MAX.
112FSB = 112MHz memory or 149Mhz memory, as 112MHz bus speed gives you the option to add PCICLK to FSB for total memory speed.

Of course this memory gain is not the only thing increased by choosing a LOWER fsb.
133FSB uses 33MHz for other buses (1/4), 66Mhz for AGP, (264Mhz 4x AGP).
112FSB uses 37MHz for other buses (1/3). 75Mhz for AGP, (300Mhz 4x AGP).
This translates into faster video (especially with 4x agp, as 7637 3marks shows), faster Harddrive, and all other cards will be clocked faster as well. The last reason why 133MHz may not be best is limited "usable" multipliers. Running at a lower FSB gives many more choices of "usable" multipiers than 133.

 

[gtd2000]

I'll check out those settings too Robs
Do you feel any difference over 133FB though?

 

[gtd2000]

btw - how do you get the system rigs option?

 

[gtd2000]

OK then tried 112FSB HOST CLK + PCI CLK - won't go into windows...
Must be my RAM which is Micron CAS3 PC133...

Finally got down to 105FSB with HOST CLK + PCI CLK and I got Turbo/CAS3 = 483/571, Turbo/CAS2 = 509/598
However tried 133FSB + 4 = 137Mhz FSB Turbo/CAS2 = 563/617

Try running your benchmarks at 133FSB + XMhz settings and see if it improves things for ya too
