how do I get more then 12.5X on athlon xp?

[Binox]

hi, I got the tbred A 1700+ on an old KT133A chipset, so my max is 133fsb
I tried going higher, but it's not stable and I'd rather not overclock my motherboard...

so my max is 12.5 x 133 = 1666mhz )-:

I know this CPU can make at least 1.73 or 1.8ghz!!
and I remember reading about a bridge that you connect to enable the higher multipliers (13 and up)!!!
does anyone know how to do this?

I know how you get the lower multipliers from a cpu above 13 by default - all you have to do is connect 2 pins on the bottom of the cpu... but I don't know how to get the higher ones )-:

get yourself an nforce2 board that unlocks the multipler

 

[Binox]

yup, I will be, but I'm gonna get a tbred B with my nforce (-:
but until then, I want to run at 13 or 13.5 x 133 instead of 12.5 ...

so you don't know how I mod the CPU?
does anyone know?

and all nforce boards will allow me to go above 13? or just certain boards?

thanks shady06, but I read that article and it talks about the 2 pins on the bottom which gives the lower multipliers on tbred and barton which are above 13 by default... so if you need to raise your fsb and want lower multipliers, you can do this mod..

but at the end of the article, it very quickly says "With the XP2800+ (TBred), the situation was different in that the mod opened up all multiplier settings from 13X to 22.5x but that is not the point of this article"
is this true? so if I connect the pins on a 2100+ for example, I will get lower multipliers
but if I connect them on a 2000+, it would give me the higher multipliers??

 

[Corporate Thug]

i dont know enough to make that call, sorry. i dont want to give any advice to fvck up your cpu

 

[Binox]

ok well does anyone else know?
I remember reading about a bridge on the top of the cpu, just 1 bridge that you connect that would give you higher multipliers...
I don't remember where I saw this, I should've bookmarked it

does anyone know of this mod?
or any other way to get higher multipliers from a 1700+ ?

Here's the deal: your motherboard has a KT133A chipset. End of problem resolution. Time to join the 21st century, and get a real motherboard if you want to play in the big leagues. Besides, any decent current m/b will handle any Athlon XP chip you want to throw at it down the road.

http://www.beachlink.com/candjac/index.htm link to Workarounds article, has sections specifically on the 1700. Have to open 1 or sometimes 2 L3 bridges, depends on the mobo.

That's about the most Useless and Crappy reply to a thread I think I've ever read. If that's the best help you can be around these forums, maybe you should be find some Other forums to TROLL around on.

thanks a lot johncar!! this link will be very useful

I haven't read it all yet, but I think this is what I needed

I'll let everyone know if I do reach 13 or higher on my old KT133A w/ 1700+

JohnCar was put on this earth to explain this.

Are you planning on doing a full hard mod of the L2, L3, and L4 bridges? Sometimes modding the L10 and opening L1 doesn't work (well it didn't in my case).

Oh, I see. So, instead of replacing an obviously out of date motherboard with the archaic KT133a chipset, it's a much better idea to physically modifiy the CPU? When a decent ECS m/b can be had for $50 or less?

No, I'm sure your degeneration of my post is much more helpful to him, than something with any actual information content.

Shut it pspada. Your post was pointless. You didn't answer Binox's question. Not only that, but upgrading his mobo would do ABSOLUTELY NOTHING FOR THE MULTIPLIER. Even if he bought an NForce2 board, he would have to modify the Cpu's bridges to get multipliers over 12.5x because they only can change multiliers for T-Bred Bs.

Oh and just for future reference, there is no such thing as "a decent ECS board."

 

[kylebisme]

you can get a gigabyte/via board with 6 dip switchs which will give all cpus access to everything from 5.5 to 18.

 

[Binox]

very interesting guys...
I know my board sucks!! it's really old, and it is the next thing I will be upgrading...
I already got myself 1gig of cheap kingston ddr333 cl2.5 (I got this for real cheap otherwise I would've got ddr400)
and I will buy an nforce2 board with a NEW TBRED B!!! my friend just got one, the 2100+ (1.73) o/c to 2.24 ghz!!!!!!!

so I'm definetly getting that!! BUT, meanwhile, I like to play around with my current system and tweak it to the max...
wouldn't you?
this way I might be able to sell it for a bit more aswell

so I've been reading this http://www.beachlink.com/candjac/Workarounds.htm and it seems that I have to OPEN a CLOSED L3 bridge :S

so I'm not sure, is this safe? what do I do? how do I do it?!?
should I just do like pspata says and wait for new mobo?

 

[pspada]

Well, perhaps an ECS motherboard is not the best choice - I would never use one in my main machine, but I have serveral clients using them for in what needed to be very low-cost systems. So if you are going to sell it and the chip anyway....

But even my older KT400 m/b allows me to change the multiplier and FSB speeds entirely within the BIOS for any Tbred or Barton processor, no chip mods necessary. I believe this is the case for any good current NForce2 based motherboard, unless you are trying to drive a Barton way over the 166fsb speed, which may require cutting the 3rd L12 bridge.

Regardless, I would NOT mod my chip trying to make it work better with what is basically an obsolete motherboard. Forget about the chance of screwing up the chip, or removing any resale value, what if the mod does not work properly on a new motherboard, should you want to try it in one? When you also factor in to the equation that a new nf2 motherboard will support any newer Athlon XP processor you might buy as well, it seems to tip the scales in favor of getting a new motherboard. Besides, it allows you to defray the cost of buying a new mobo and chip at the same time - get the m/b, put this chip it in and find out what it can do. Then you can buy a new chip, Tbred or Barton, a paycheck or two later.

Or perhaps this is a better idea? Get the ECS & Tbred 2200+ (or whichever) deal at Fry's for about $100. Put your old chip in the ECS m/b, and sell it to someone else. Then get a new m/b, and put the new chip in it for yourself, oc'ing as you like. How's that sound for a good wheelie dealie?

You can open a bridge with a brand new exacto knife, but I hear the preferrred method is to use a 9V battery and a couple of wires and pins, and blow the bridge.
This bridge can be easily closed again with conductive paint. This is much easier than unlocking an old palomino chip. You can mask off the area, there is only one bridge to paint over instead of 5, and there is no laser cut pit to fill in first.
I have never used the 9V trick, but there are some links about it at amdmb forums. Here is a link

 

[pspada]

The idea of doing these things to my chip always gives me the heebiejeebies. I'd perfer to give myself a vasectomy using a mirror, a Tom Mix pocket knife, and moonlight on a cloudy night.

 

[skyking]

so you value a $40 (max) t-bred A over your cojones? THAT explains everything!!

I have been running my new Tbred-A XP 1700 on Asus A7V 1.02 (VIA KT133) at the speed of 1716Mhz (17*101). Basically what I did was to cut the right-most L1 bridge (If I recall correctly), then I sent my multiplier thru my onboardf dipswitch to 17x, (I set to 9x, since I have cut the bridge, it is being seen by the cpu as 9+8=17).

Take a look at the link, more detail and discussion inside.

 

[Binox]

hmm, very interesting!!
did you mean right-most L3 bridge? not L1 bridge..

anyway, yesterday I cut right-most and middle L3 bridge (3rd and 5th), by defaul they were all closed (11x) and by opening 3rd and 5th I should get a multiplier of 13x...

this caused my system not to post unless I hold down the insert key (KT7 option) which puts the cpu back to default and it displayed 1300mhz (13 x 100)...
then I get into bios and no matter what I try, no post!!
the only way to post is by holding insert and then I get 13 x 100

so it's definetly my board which is too old, I even tried 5 x 100 (hoping it would do 5 + 8 = 13 x 100) but that didn't post either... I guess the A7V is better for supporting this..
I ended up reconnecting the 2 bridges, and now everything is back to normal and my max is 1.66ghz still...

Nforce boards can unlock ALL athlon XP multipliers?

Binox,
This suggests a problem unique to the KT7 (and A7Vs). Read about it at http://www.beachlink.com/candjac/index.htm link to Workarounds article and focus esp on the section re "13X thru 14X no boot but 15X and up does". You will find a legacy Duron/Tbird circuit which causes problems with 5 bit Tbreds....problem fully explained, and there is a workaround for it discovered by "KF". Not positive it will solve your problem but the symptoms are similar. Worth a read...see what you think...run some tests...try the workaround???

BTW...We would think that your system would have booted at 13X133 at least if the bios Multiplier mode was set to Auto/default since you did reset the default to 13X. Were you in Auto mode...cause that seems to disable the offending circuit/problem.
