no really?
this article aims at showing the difference in raw CPU power.

Sorry if this comes over as aggressive RuB87 but you are really offtopic here.
I know I can get +220Mhz FSB on this KR7A Abit, but there is no NEED to show this in the article.
I already pointed out that by just increasing the FSB you can get a nice improvement in performance.

ahh k put me also in the list plz:(

Yo Jmke,


Nice article on the Xp1700+, Unfortunatly I allready bought a Xp2400+ but if I can believe the information I got from this site
my processor is a XP2700+

So can you tell me how to unlock it in the easiest way, this is the first time that I am going to unlock a processor so I'm a bit concerned.

Information I got is below

Athlon XP Processor High-end
Core Thoroughbred-B
CPU Model 8
Performance Rating 2400+
Working frequency 2000 MHz
Package Type OPGA
Operating Voltage 1.65 V
Max Die Temperature 85° C
L1 Cache Size 128 KB
L2 Cache Size 256 KB
Multiplier 15x
FSB Frequency 266 MHz
Stepping Code AIUHB
Manufacture Year 2002
Manufacture Week 48
Production Batch F
Batch Production Number 0264
Downgraded from 2700+

in a recent motherboard these TbredB chips come unlocked already :)

Maddy 23rd March 2003 13:28

Yo,

Bad luck then I guess I have a Leadtek K7ncr18dPro motherboard with no multiplier options (overclocking is not necesary) and I thought that when I unlocked the downgraded xp2700+ it would show automatic Xp2700+ in the bios instead of xp2400+ as it does now.

jmke 23rd March 2003 13:35

nope :)
you need a motherboard capable of changing the multiplier :)

too much hassle soldering/cutting bridges otherwise

Maddy 23rd March 2003 14:01

Any good suggestions for such motherboard, the cheaper the better.

jmke 23rd March 2003 14:03

any KT266A/KT333 motherboard will do
you can find an Abit KX7 with raid for ~60€

I'm going to buy myself an awesome 2400+ (most likely AIUHB) and I'm wondering if it would also be auto-unlocked on MY mobo. I have a rather old chipset, but a relative new revision: MSI K7T Turbo2 - kt133a - supports max cpu: 2600+/266 (!!!)

My question: are all the L1 bridges factory-connected, giving me the chance to change to mp in the bios without any physical modification of the cpu ?

/mod: offtopic: 43 to 44°C stressed, luv those warm days while mom is leaving the central heating off. =)

jmke 24th March 2003 21:46

"kt133a"

I wouldn't count on it :)

But are the L1 bridges of the 2400+ all factory-wise connected (or "not cut") before they leave the labs ? (because if so, I could up the mp a bit, from 15 to 16, and the fsb a slight bit, pushing the limits of my kt133a with an athlonXP @2.2GHz =))

jmke 25th March 2003 16:33

the L1 bridges are connected
but they don't control the MP over 13x.. I think.

Could be darn true, my bios only allows me to select a mp varying from 5.5 to 12.5 with my duron inserted.

"Darn !" :/

/mod: I remember something about the the last L3 bridge, more specific: if it was connected, you could select an mp-range of 5.5 to 12.5, and if not it was 13 to 20 I think. Most likely (mp is 15) the L3 bridge will be cut, giving the bios the signal to use the alternative mp-table, enabling the mp's ranging from 13 to 20.

Do I have misunderstood something, or is there still hope ? :D

So now i got my 2100+ running at 17*133MHz = 2266MHz. I had to up the voltage a bit, itīs now 1.65V instead of the default 1.6V to get it perfectly stable (from 2600+ processors actually use 1.65V as default). The other way to overclock this fantastic mobo is upping the FSB. That way I got it up to 13*160MHz = 2080MHz at 1.6V, but the USB-controller seemed to drop occasionally. You can get these speeds with proper aircooling and new AIUHB (0250 or newer) processors without problems (actually latter example needs some good ram too). Now I have put watercooling in my case, so itīs time to do some testing with higher voltages. 1.3V and 1.425-1.80V(0.025V increments) are the voltage choices in 3.6 BIOS by the way. Hope my experience gives faith to those, who are not sure this mobo can handle these new TBreds. Yes it can! Now itīs time to test if this 2100+ can brake the 3000+ barrier ;-)
*dancing around* :banana: :D
