Help a Noobie overclock a tbred-b 1700+

[pug_s]

I brought a Tbred-b processor AXDA1700DUT3C with a giga byte 7vax with kt400 chipset. The bios allows you to change the multipler via switches and via the bios menu.
1) Do I have to make any modifications to my processors to change the multiplier settings? If I have to, how do I do it?
2) Is the fsb locked? If so, can I change the fsb to 166 mhz, I believe the motherboard supports 166 fsb.

Thanks.

With a T-Bred B, the multiplyer should be unlocked. You should be able to adjust this in the BIOS. As for the FSB, well, that is unlocked in almost any chip, and is for yours. It should also adjustable from your BIOS. Enjoy your OC'ing fun!

Overclock as much as you like. Bear in mind though, max multiplier will be 15, unless you modify the chip.

<ax multiplier will be 12.5

How can I make the multiplier more than 12.5? If not, I think I will try to change the fsb to 166...

type in unlocking the athlon XP in google or whatever


search the net for unlocking there are a lot of ways to do it and a considerable amount of articles about it

SL6EF OC's GOOD

You need to modify the L5 bridhes. Go to the CPU overclocking question and ask a question about higher multipliers of a Tbred B and then it is very likely someone called 'phosstpok' (sp?) will reply to you telling you everything you need to know.

Actually, I was able to overclock past 12.5x multiplier without modifying the L5 bridge. This processor is the retail version of the athlon xp. Guess this processor is really unlocked. The motherboard wasn't what I expected because I can only change the multipier via jumper.

It's the L3 bridges. However KT400 owners don't need to mod the Tbred B XP1700+. Abit NF7-S (nForce2) owners don't need to either. All the multipliers are availailable, 5x-18.5x and more.

Wow! I didnt realise they were all available on nforce2 / KT400 mobos, even more excuse to upgrade to an nForce2! Sorry I got the 'L' part wrong, and your name

Actually, I only know that the Abit NF7-S opens all multipliers, even for low-end Tbred B's like XP1700+ (as long as it is unlocked, L1's closed).

The Asus A7N8X (and deluxe) don't open the higher multipliers for Athlons with multipliers of 12.5x or less. I don't think (not sure) A7N8X opens the lower multipliers for Athlons with multipliers of 13x or higher.

Don't know about any other nForce2 boards.

it doesn't unlock multipliers of 13 an lower. I'm using an Athlon XP2700+ and having the same issue.

Do you mean the A7N8X?

I'd have to guess that since NF7-S doesn't have the problem that it's possible a future A7N8X BIOS can fix it in that board.

You could mod your chip, close the 5th L3 bridge.

You can also do the wire trick and connect the 8x bit LO, socket pin AJ27 to AH28 (Vss - ground).
