Hello pzed22
Just put my XP-M 2600+ into my old KT7A Raid and would like to try the Mainboard mod but the pics are not online anymore. Could you upload them again somehow or does anyone know another link with pictures about the same mod?
Thx
German version:
Habe hier grade meinen XP-M 2600+ in mein altes KT7A Raid eingebaut und wollte den Mainboard mod mit dem Widerstand machen, die Bilder zum mod sind allerdings nicht mehr online.. hat irgendwer nen anderen Link mit Bildern davon, oder kann sie mir evtl. per mail schicken?
Waer total geil, der kann naemlich mehr als die 1815Mhz mit 12,5*145/34

Here is a neat trick to get your FSB to 133:
Cut the 4th L3 Bridge, and make sure you cut it a little too deep. Now paint the bridge again. This grounds the 4th Bridge to the CPU, and allows the 133 FSB to work. I did it with my KT7E, which doesn't even officailly support 133FSB. Side effect: It reduces all your multipliers down 4X, but you can now paint the 5th L3 bridge and it will work with higher multipliers.

Mistake!
I said Palomino & thoroughbred will both work the same, but now some more detail:
XP1500 to XP2000: This resistor mod works fine.
XP2100 and above: These CPUs have AJ27 already ON by default. If you don't mod. the board, you should get >12.5x already. You might still want to install the switch, but connect it to GROUND (Vss) instead of Vcc. This is essential if you have cold-boot problems like me (you switch it ON to get <12.5x if you can't boot).
-- Veröffentlicht durch pzed22 am 11:50 am 5. März 2003
The problems you could get is trouble unlocking the CPU and soldering the wrong pins and causing a short.
Of course, you should verify that your CPU has been unlocked successfully before beginning.
It's unlikely you'd loose your motherboard, unless you solder the wrong pins.
You can break your CPU if you don't insulate the pits between L1's. But this is an unlocking issue.
I don't have a digital camera, maybe someone else here can take a photo if they've done the mod.?
As for the core, Palomino and Thoroughbred should work just fine. Their BP_FID pins are compatible, so it works with both, BUT the multipliers you get are different. For example, Palominos only have "... ,16.5,17,18,20.5" but some new thoroughbreds have other numbers (you'd have to google for them, I don't remember). Either way, you should find a multiplier that's close enough to what you want.
karabulo: A 1700+ at 2GHz is amazing, I'm jealous now :) If you can't get other multiplers, it probably means some L1s didn't unlock properly.

hi, I would like to put an XP in my old Asus A7V.
what are the problems I can get?
Lose my MB?
Lose my CPU?
can somebody make a picture of his mod? (at the back of MB) to see what it should look like :p
and just to be sure: I don't especially need a palomino core? a Thoroughbred will do the job as well?
Thank you all for the inspiration you'll gave me!!

@karabulo
I've got an 1700+ Tbred B working perfectctly on my Abit KT7 Raid, and before it I had a 1800+ Tbred A, and they work perfectly. So the chip will work on your board if the bios support it.
The question of the multi-mod.... I've not test in a KT133A chipset, but I think it must work in any chipset, becouse the mod work on the processor, not in the board. I tried the multi-mod on a thunderbird, and didn't word with my board.

Hi, I've just tried your KT7_RAID mod!! I've bought an XP1800+ and added the multiplier(mainboard) modification according to your info. I use and 100ohm resistor instead of 180ohm->works fine.
The CPU is now running happy at 110x(8,5+8)@1,88v=1826Mhz!!
THANX FOR YOUR INFO!! KEEP UP THE GOOD WORK

My idea is buying a Thermaltake volcano 7+ (Entire copper heatsing with thin fins), and whith this, I think i will reach better overclocking than using any palomino core (even aroia or agoia).
The thoroughbred 2200+ runs at a default voltage of 1,65 while all palominos does this at 1,75.
As i say, i think that using a copper heatsink capable of absorb the heat from core from himself, i will get more mhz with a tbred than with a aroia-y

KS:
1) Only on Thunderbird & old Duron. L6 is irrelevant on XPs.
2) Forget FID, it's not needed anymore. BP_FID controls the multiplier in XP & Duron-Morgan. In the old days you had to match up BP_FID/FID, but not anymore.
Tassadar:
Thoroughbred should work the same way, if it's 2100+ or LOWER.
If L1 is cut, you'll have to join them. I havn't tried it personally though.
Doesn't thoroughbred "A" run hotter though (small surface area)?
-- Veröffentlicht durch KS am 16:44 am 18. Okt. 2002
May I ask one more question?
- Does L1 and L6 (FID) has anything to do with each other?
- When we talk about multiplier setting, do we talk about BPFID (L3 and L4) since L1 is connected or L6 is disabled?
I am getting confused about FID and BPFID.
-- Veröffentlicht durch pzed22 am 13:36 am 18. Okt. 2002
Because AJ27 is the new pin added in AthlonXP (BP_FID4). Older motherboards have this pin NC, that's why you need the resistor & switch.
Don't bother with durons, XP1600+ is dirt cheap :)
-- Veröffentlicht durch KS am 13:22 am 18. Okt. 2002
May I ask why AJ27 and VCC?
As fas as I know, BP-FID pins (for Duron) are
- AN27= BPFID0
- AL27 =BPFID1
- AN25 =BPFID2
- AL25 =BPFID3
These pins are either pull high by connecting to Vcc or Pull low by connecting to GND.

Great! today I have place an Athlon XP 1700+ on my abit kt7 raid and it works perfectly, I even don't have the timing problem you talk about (at least not in the 5-10 times I have reset, put-off -> on, etc).
The question is that this processor was not mine, but a friend's.
I'm thinking in wait a bit and try to get a 1700 - 1800+ with thoroughbred 'A' Core, whose will cost me the same than a 1700 - 1800+ with Palomino core.
Will the thoroughbred work on my board?, and another question: unlocking the thoroughbred is easier than a Palomino, is needed to paint only one bridge, it isn't?
In the case the thoroughbred would work on my board, will multi-mod work unlocking the processor with this bridge? or I would have to unlock the five L1?
(The true question is not how many bridges I would have to paint, I don't mind, always when multipliers above 13 will be selectable with multi-mod)
Thank U very much!!! :D

Yes, my board is a KT7, not KT7A, when i bought it the rev A was still not avaiable, KT133a appeared on market 4 or 5 mounths later.
I would wish it were a KT133A, hehehe
Other question is that when I made the mod with my thunder I experienced many stability problems, even I had to reinstall windows, and for a time I though I had broken the CPU or the mainboard, now it seems to be ok, but at once I'm still not sure it will be completely ok, i will have to see my system running ok during some days for be sure.
I pray for my CPU and board, :P
-- Veröffentlicht durch pzed22 am 5:33 am 9. Okt. 2002
Tassadar: Are you sure your board is KT7 and not KT7A?
You were right, the resistor mod doesn't work with thunderbirds.
I'm using A9 BIOS myself, and it works fine. But XPs arn't officially supported, so there is some element of risk you have to take. Then again, look at this thread, 3 people tried it, 3 people succeeded :)
> and other question, the multi mod doesn't work with my thunderbird, will it word > with an XP???
Yes, it's for XP only.
-- Veröffentlicht durch Tassadar am 4:51 am 9. Okt. 2002
I have an Abit KT7 Raid with an Athlon thunderbird 133 bus. due to this my CPU has a default multiplier of 10,5 and max i can get is 13, so now i've got my cpu at 1366 mhz and 1,5v.
The question is i have made the multiplier mod that is explained here, and it don't work, I suppose don't work with thunderbirds.
In other hand, I see some of you have no problems running an XP on chipset KT133, even Pzed22 has the same board than me. I have the latest bios of the official abit webpage, and here i don't see anywhere any mention about supporting duron morgan, so i don't know if i will be able to run a morgan, and even less, an XP.
What bios do I need to run an XP on my Abit Kt7 raid? I have the version kt7a9, whose I downloaded from official abit page, will this work??.
and other question, the multi mod doesn't work with my thunderbird, will it word with an XP???
Thanks very much to all

Miky: If you got ~1.7V at AJ27, I think the only problem could be that the 5th L1 bridge wasn't connected properly. I'd try touching it up a bit. Note that the 5th L1 controls the +8X line, which you can't seem to get ON.

Pzed22: the problem has been solved. It is not timing incompatibility. The CPU was badly unlocked. I have repaired 4th and 5th L1 bridge and now it works fine. The only problem is same as yours - powercord disconnection..but I can live with that.

You've right which value of core voltage I set in BIOS than I measure it on AJ27 with switch ON.
I really don't know what to do :'(
maximum which I can reach without this modification is only 120 * 12.5 (1500) and it sooooooo bad :cry:

>What do you mean by 'it doesn't work'? No post, or wrong speed?
post is OK, but same speed like with switch off
from my view it is like I never connected rezistor and switch (ON or OFF)
I'll try measure the voltage you gave me, thanks
-- Veröffentlicht durch pzed22 am 12:43 am 4. Okt. 2002
Miky: If you have a multimeter, measure the voltage at AJ27 while the computer is on (and switch on). You should get about 1.7V. If the switch is off, you should get 0V.
What do you mean by 'it doesn't work'? No post, or wrong speed?
-- P>
-- Veröffentlicht durch Miky am 9:47 am 4. Okt. 2002
I change my BIOS to A9 too, but it still doesn't work :o(
I think, that resistor with switch works OK, but my board ignore it.
When I measure resistance between these pins through socket with switch off, that's none resistence, but when I switch it ON there is 180ohm.
I have KT7-RAID, can be here the problem?
-- Veröffentlicht durch pzed22 am 7:36 am 4. Okt. 2002
It's possible Haris, but I think the reset-at-bootup is just the AthlonXP timing incompatibility. KT7 bootup timing is not 100% compatible with XPs, and reseting gets past this problem.
Sudhian KT7 FAQ says:
"AthlonXP processors are not officially supported due to a minor timing problem that can require you to hit reset during a cold boot. Unofficially, however, few people seem to experience this problem and these processors work fine."
I don't have any other power hungry devices like you though, only my CPU. I think AMD recommend from 300W and up don't they?
http://www.amd.com/us-en/Processors/ProductInformation/0,,30_118_756_3734%5E4348%5E4376,00.html
Check your 5V and 12V lines while at 100% CPU usage, if they are dropping alot, you know you've got a problem.

-- Veröffentlicht durch Haris am 0:51 am 4. Okt. 2002
Yes, that what I have thought. My idea is this: The computer is starting again and need more amps (hdd spinning up,chcking all the cards and drives,spinning up the coolers etc.) So the power sup. is overloaded. It could also be the reason why I can not go over 1600Mhz even or 1.85V...higher freq. + higher voltage....more amps needed....
Am I right?
I am going to try 300W or better. (Fortron)

Yes shure, AMD recomdes for their CPU's 20 A for the 5 V string and 15A for 3,3V.
And your Gf4 Ti 4200 needs a lot of Voltage too.
Good powersupplies for your System are the Enermax 353 W EG 365AX- VE or the Leadman LP-6100D.
-- Veröffentlicht durch Haris am 23:42 am 3. Okt. 2002
(((((((((((((((((-: I have average No-name 250W powersupply...
I have Gf4Ti 4200, Athlon XP at 1600Mhz (higher voltage), massive cooler Titan D5TBTC,modem,sb-live,ethernet card,one HDD,CD-RW,optical mouse.
It is possible that it is too much for 250W?? It could really by the couse of the problems...
I have strange problem:some times when I restrt my PC from Windows or by pressing CTR,ALT,DEL...it does not boot again (blank screen) I have to push reset button...then it normally starts and boot up.....
Otherwise the system seems to bee running stable. I am suspecting weak powersup. or wrong unlocking of the CPU??? What do you think?
ThanX
-- Veröffentlicht durch pzed22 am 4:40 am 1. Okt. 2002
Miky: It doesn't matter when you switch it, it will take effect at the next reset. It can't be perminantely connected, because of Haris's problem.
I don't see the multiplier at POST, but I see the speed, something like:
"Athlon(tm) Processor 1700MHz".
Haris: I have the same cold-boot problem. Only solution I know of is, never remove the power cord ;) I thought it was my weak power supply (265W), but maybe not.
It's a shame that a AGIOA doesn't work at 1700mhz, they usually do. 1.6g is
pretty good for a KT7 though!

Hi all. I have managed to do this modification according Pzed22. It works (almost) perfectly. The PC is stable. I have brown AGOIA 1600+. It is running 16*100Mhz. 17*100 is unstable even on 1.85V (highest possible in this board)
The problem is: If I disconnect powercord and then connect it back the PC will not start. (Blank Screan) I must switch off the resistor/switch, start the PC on 800Mhz, then switch off (only by the ATX switch), turn on the resistor/switch and turn on the pc by ATX switch. Then it will work OK on 1600Mhz...
It is very strange.
PS:Pzed22 can you tell me your bios version?
ThanX

Hi Pzed22,
can you exactly tell me, when I have to switch from Aj27 to Vcc.
While post or power off or in BIOS?
and if it is while power off why it can't be permanent connected?

PS: I have Athlon XP 1600+ stepping AGKGA. Is he overclockable?
(Geändert von Miky um 13:25 am Sep. 28, 2002)

Insulation of the gaps is very important! Make sure you don't get any conductor in the gaps, or you'll short all the L1s to ground (bad!).
This is what I did, but you can find lots of different methods on the net:
Light a candle, drip some wax on a plate, then rub a Q-tip in it and let it DRY.
Now rub the Q-tip with dried wax over the L1s. Little wax bits will start to fill up the gaps. I found this to be safer than super glue.
I'm not sure about graphite conductor. You shouldn't make more than about 200ohm across the length of the L1's. Silver is probably best.

I have bought an XP 1600+ (brown AGOIA) but I am not able tu unlock it. I have to use graphite conductive paint, because all the local stores were out of silver conductive paint. I think the el. resistance of my paint if too high? Am I right? Or I am making another mistake?
Tomorrow I am going to buy the silver conductive paint. I hope....
I tried to use the "graphite" several times, but it was impossible to set 11 or higher. When I set lower then default 10.5, the system did not started.
Any suggestions? Especially about the insulation of the laser cuts before painting the conductive stuff...What can I use for this insulation? Is it necessary?

Yes, you can use up to XP2000+ with this method.

-- Veröffentlicht durch pzed22 am 5:49 am 11. Sep. 2002
Maybe this picture will be more clear: 
The two points are "aj27" and "vcc". Yes, the resistor and switch are under the board.
I used a XP1600+ ("AGOIA" core), overclocked from 1400MHz to 1700MHz.
Note1: Multiplier 14x did not work for me. I don't know why, but the lowest that worked was 15x. 15.5, 16.0, 16.5, 17.0, 18.0 also worked fine.
Note2: To select 15x, you must choose 7x in the bios and turn the switch ON.
Note3: The CPU must be unlocked! All five L1 bridges connected. You should unlock the CPU first, and make sure all 5x to 12.5x work before installing the resistor/switch.

Yes it did work, but I didn't cut the bridges. Here's the result:
This is how I did it:

2) Insert new unlocked chip (all five L1 unlocked).
3) Connect a 180 Ohm resistor and switch from AJ27 to Vcc:
4) Boot at 17x100 = 1700MHz!
Performance is not bad either :)

It will Work. If your Mainboard is able to handle a Duron > 1000 Mhz (XP Core) it will work also with your XP 1600+ if you change the Multiplier to 14 by cutting the Bridges! Here in the Workshop you can see how to do!

its a lot faster, the kt7 is reeeeeeeaaaaaallyyyyy slow!
-- Veröffentlicht durch pzed22 am 18:02 am 12. Aug. 2002
Maybe a better idea...
Since these boards don't understand the new 5th L1 bit, leave it locked, but unlock all the other L1 bridges. Then swap L10 around (add 8X). This should let me select any multipler in the bios, from 13.0+.
5.0->13.0
5.5->13.5
6.0->14.0
6.5->14.5
etc...
Work would involve: Join total of 5 bridges, and 1 cut.
Does it sound reasonable?
Anyone tried it?

Ok, here goes. This is just a theory, I havn't got the guts to spend money on trying it (yet)
I want to extend the life of my good-old KT133 board (ABit KT7). So what about putting an XP chip on it?
1) Buy a XP1600+ (1400MHz). This is cheap, $60 on pricewatch.
2) Paint the bridges to a 14.0X multipler (but keep it locked).
https://www.ocinside.de/html/workshop/socketa/xp_painting.html
3) Turn it on, and hopefully see "14.0x100 = 1400Mhz" on the screen.
If it stalls during POST, just hit the reset button. This should avoid the
XP bootup timming incompatability.
Now blow holes in my theory :)
P.S. Are the "reserved" multiplers okay to use?
