So how do i tell which 2600 i have?

[hugorudd]

This is all very confusing.

My CPU is one of the 'magic' batch of 1800s that are actually downclocked XP2600's. I got it shop-unlocked for less than half the price of a 2600 at the time. How do I tell which version of the 2600 was downrated for my proc? Specifically, is my processor a 266 or a 333 clock processor?

I can see that the difference according to AMD's technical spec in terms of performance is the posted actual MHz; when it's all running according to specs, the processor is absolutely stable at 29deg and 2086MHz.

This suggests that it's a 333mhz chip, but i need to be sure for an upgrade. No point in going for a fastass mobo and PC3500 memory if it's all going to chug along trying to mark clock cycles.

Before anybody suggests checking numbers, remember that it's badged as the 1800+. (Trying to run it at 1532 now makes it post a temp of less than 20 degrees!)

Any ideas? CPUID gives the revision and stepping as 0x681, and CPUinfo is as useful as it's always been.

Thanks.

Try pluggin in the three sequences of numbers on your processor into this doohickey .

Ok, my bad, I didn't read about the numbers.

I have had good luck obtaing info with AIDA 32

[hugorudd]

Does the fact i'm running at 166 clock ratio prove it's meant to be a 333 clock processor, or am i going mad again?

Go ahead and post the numbers on the die.

[hugorudd]

i already made the point that i was trying to figure out the type without all that crap. Surely if it was a 266 processor, it would have to run at 133 fsb? But my machine runs at 166fsb perfectly stable with the processor posting a 2086 speed. I dont want to go removing the massive cooler from the machine if the processor isn't going anywhere!

and another thing... i don't want to buy anew processor, i just want to overclock it. anybody think that it makes sense to upgrade to a kt600 board?

Uhh, NO. I have a 1700+ designed to run at 266FSB running at 400FSB.
BTW.. if you really want to OC, get the Nforce2 chipset

[tony_j15]

hugor: 133x2=266. 166x2=333. I think you answered it yourself I would reccomend getting a Asus A7n8 motherboard, it uses the nForce 2 chipset and is the best dang thing for OC XP's

get an nforce 2 mobo if your going to overclock . asus a7n8x or abit an7 or nf7 all 3 are great overclockers .

all cpu's are " badged " cpu's , do you really think they make different type ? they all come from the same silicon waffer . just some tested can't run with the specs that they want them to for certian cpus . so they are downgraded . or they are badged to how they make the most money . so in times that the lower end type are selling lots of volume then thats what they are badged and they make there money in volume and some are badged at higher end and they make more profit per cpu . it is all about marketing .

for example if you look at the cpus today they are all the same core, thorton. but a xp2000 has the extra l2 cache disabled . but it is the same as a xp3000 .

think the numbers won't give any insight is wrong . the speed will read the same but you want to know about the core and the model . that will always be the same.

this kinda goes back to my first comment on cpu's . they are all made from the same platform so potentionally they might be able to run at the same speed as the highest cpu that was out the time that yours was made , or even higher if you are lucky .

So should i bother getting DDR400 memory if the processor is a 333? I guess there really ought to be mileage in the processor yet at this temp and voltage.
