A7V333 + 1700+ JIUHB, only multipliers upto 12.5x

Oreo77 · § #1 04-02-2003, 06:45 AM

I've got a A7V333 and a 1700+ T-bred B (JIUHB) which is unlocked but I can only access the multipliers below 12.5x. Is there anyway you can use the multipliers over 13x? Can I modify the CPU or motherboard in someway to do this?

The A7V333 only supports 'high' (>=13) OR 'low' (<=12.5) at any one time. This is determined by another bridge on the CPU (L5?) that you need to toggle.

(Sorry dont have link to hand to be more precise on which bridge it is. Not sure if software ROMSIP would open the option, but also has other effects.)

You can only access 13+ multi if you have a 2100 or higher because these chips have the last L3 bridges cut.

I recommend 2100 over 1700 if you don't have a Nforce2 board because you will need higher multi to get a better oc with 1700 on these old boards. On NF2 boards you can use high FSB, so lower multi is not a problem.

So if I want access to the higher multipliers I have to cut the last L3 bridge? Which one is it, the one towards the center of the CPU or the other direction?

I've also heard of a 5bit mod that you can do on the motherboard to allow all the multipliers to be used? Is it difficult?

I don't know about that 5-bit mod.

You should be able to find the label L3. The connection you need to cut is the 5th of this L3 bridge and that is the furthest one from the label.

You mean the furthest away from the "L3" text?

If you count from the top of the L3 bridge, you need to cut the most bottom one. And if I remember it correctly, it should be furthest from the L3 text.

Try this thread in the O/C forum (or do a search in o/c forum for multiplier pins).

Seems you have 3 options - paint the last L3 bridge, paint some pins on the bottom of the CPU, or make your own 'jumper' that you insert in the correct CPU socket holes.

Your method is for accessing multi lower than 13 on a CPU that is above 2100.

Oreo77 What is your mobo's revision?

I have gone over some site that explains how to use 13,13.5,14,17,21 multis without bridge work - wires only.

OLD___NEW
11x_____13x
11.5x___13.5x
12x____14x
12.5x___21x
13x____No change
13.5x___No change
14x____No change
15x____17x

PS, how do I attach an image file?

This is a multiplier translation table, it is only enabled if 5th of L3 bridge is cut.

Duzen · § #12 04-03-2003, 06:30 PM

They said that you need to wire two groups of legs and you need all the L1 and L3 bridges to be closed. (are they already closed on 1700?)

Not English, pictures though.

Bump..

dukla2000 · § #14 04-06-2003, 04:35 PM

Yeah - I was wrong earlier: you need to cut the last L3 bridge, not paint it.

The gospel (IMHO) on Athlons is either at Ed's page or John's page.

I have a TBred 1700+ on an Abit KG7 that has the same issue with the x12.5 max multiplier. After reading the workshop on this site regarding which L3 bridges to cut.

http://www.ocinside.de/go_e.html?/ht..._painting.html

I took the plunge and cut the 4th and 5th L3 bridges to code my cpu with a x15 multiplier to change the chip into an XP2400+.
This could work for your mobo too. At the moment I am sitting here at 2250mhz using the x15 multi and 150 fsb which is not bad for a cpu costing £43!!
