Duron 750 OC'ing question (regarding bridges)

I am planning to build a new KT266A DDR system using an 8KHA+, AK31A, or AK35GT.
I have an old Duron 750 that I would like to try to OC to at least 930 (7 x 133) or higher and use for a while until I can update to an XP.

<U>I plan to do the following:
</U>1) Unlock the multiplier by connecting the L1 Bridges
2) Set the core voltage to 8.5 by connecting all L7 Bridges
2) Drop the default multiplier from 7.5 down to 7 (for initial bootup) by connecting the 1st L6 Bridge

Do I need to do anything with the L3 or L4 bridges or does unlocking it with the L1 bridges allow the MoBo Bios Multiplier Settings to change the multiplier?
 
once u unlock the L1 bridge, u can changeb 7.5 to 7.x through your bios.
the L3 and L4 and L6 is to change multiplier for board that dont offer this option in bios such as ecs k7s5a.

 
Thanks, I did not think that I needed to touch the L3 or L4 bridges.

The reason that I plan to connect the 1st L6 bridge to change the default multiplier to 7 is to insure that it will boot up and run at 133fsb for those few cycles before the BIOS takes over.
This was a problem for most of the original KT133A mobos when reducing the multiplier and raising the fsb from 100 to 133.

I refer to Anands artical: VIA's KT133A - Overclocking w/the 133MHz FSB: The "Issue"

Have the newer mobos taken care of this?
 
I dont understand why you need to connect other bridges, I just connect all L1 bridges and now my Duron 700 is running at 963 mHz (FSB 148).
 
The 2 mobo u listed in the 1st post all support changes in multiplier & vcore...so just connect the L1 bridges & u r ready to go.
 
All I connected were the L1s. I got my Duron to 1136 and kept it there for awhile, but backed it down to 1050 for stability. What heatsink are you going to use? I have an SK-6.

While you've got the cpu out, look at the stepping and tell me what it is.

Thank you for your concern on this issue.

First of all, I was mistaken about the default speed of this CPU.
It is a Duron 700mhz (7x100) so I could probably just run it at 931mhz (7x133) 931 and get away with it, even if the PC did boot up with the default multiplier and the 133fsb setting.

I would, however, like to get a bit more out of it if reasonably posible.
I am not familiar enough with the steppings and how they OC'd, so I will appreciate your comments.

The HS and Fan that I plan to use is the Thermal Integration's Dr. Thermal TI-V77L.
It has a 70mm (High Output yet Quiet) fan and received very good ratings in some reviews that I read.

Here are the into. from the chip:
AMDDuron
D700AST1B
AKBA 0027APBW
91985320223
1999 AMD
Thanks,

So, you have an AKBA. You should be able to get what you're expecting from that. I have an ANCA, and those tend to hit about 1.1 GHz.

Do you think that I should go to the trouble of unlocking this AKBA and try to take it up to (7.5x133) 997mhz?
Or should I just leave it at the default of 7x and set the fsb to 133 anc be done with it?

Go for it. You may be able to break 1 GHz. A lot of AKBA cpus on overclockers.com have hit higher than 1 GHz, but they've used water cooling.
