Click to See Complete Forum and Search --> : Which Athlon XP is best for overclocking?
Hey,
I'm thinking of getting a new motherboard and processor, and maybe overclock it a bit. Which Athlon XP should I choose? Is changing the FSB the only way of overclocking? Not sure if I want to tamper with the processor itself.
I'm also thinking of getting an "old" SDRAM motherboard so I can use my 384 Mb of PC133 CL2 SDRAM with it. How much performance do I lose compared to buying new DDR RAM?
Thanks for any replies.

the AMD MP CPUs are the best for OC-ing
but non of the XP

I dunno, my xp1700+ overclocks pretty well... Have gotten the FSB stable at 144 with stock voltage, 152 with just a .025 increase in vcore and goes up to 155 @ +.050 volts.

but non of the XP I've got my XP2100+ AGOIA stepping up to 177fsb x 10.5 = 1860mHz @ 1.85vcore (air cooled) and didn't really push it. I normally run 24/7 at 174fsb x 10.5 = 1827mHz @ 1.775vcore... so I think there's plenty of room left at that 1.85vcore setting. Those are pretty decent OC numbers. I've read reports of many folks with XP1600+s (AGOAI stepping) getting up into the 1800's (mHz).

Thanks for any replies. CPU Mods (http://www.cpumods.com) did a real nice job professionally unlocking my XP2100+ ($30). They employ microwires that are microwelded to connect cut bridges, laser to cut bridges that need to be cut, and seal the whole thing in some sort of polymer to protect it when done. They test your cpu before and after their process. I was very pleased with the results.

If you have the money, get one that runs on the .13 micron process. You can push them a bit harder than the .18's. You really need to get newer DDR ram. Keeping the old stuff is like trying to hook up a fire hydrant to a garden hose.

well.. I am not dissapointed by my garden hose/firehydrant combo.... I have 768 mb SDRAM and an XP 1700+ that runs stable at 1634MHz (11 x 148)... i still get over 10,000 3DMarks on it.. and someone told me that i wouldnt ever get to 9000 with SDRAM - oh, btw, i am currently building a DDR computer to try and use my GF4 to its best potential:D

T-Bred B. I am almost certain that one can get the FSB to 333 (166*2) with the stock multiplier and good cooling. Even if not, you'll get good OCing results.

How can you tell wich tbreds are the "B" revision???

Thanks for the feedback. I see now that XPs are, generally, pretty bad for overclocking. An MP would maybe be better, but they also cost more, so I think I'd be better off just getting an XP.

How To Tell Them Apart (http://www.overclockers.com/) :t
Can't seem to get that link to work right. So scroll down to November 4 where it says PROCESSOR SCORECARD...

Forgive me, but from all the comments within this thread, I do not see how you draw the conclusion that XPs are generally bad for overclocking. I'm reading the same comments, and they look pretty good as far as overclocking goes. Perhaps you are not familiar with what the XPxxxx+ ratings mean? An XP1600+ actually runs at 1400mHz, an XP2100+ actually runs at 1734mHz. They are "performance rated" at 1600mHz and 2100 mHz, respectively.
Also, none of the commentors have provided you with any "numbers" regarding the overclocking results achieved with MP cpus. MPs may be either multiplier unlocked or partially multiplier unlocked (I forget which specific MP speeds are which), but they essentially the same architecture as the XPs. They should overclock about the same. You may have a bit more work to do to get the XPs unlocked so that you can vary the cpu muliplier, but that is about the only difference.
The TBreds are still marketed as XPxxxx+... they have a different architecture and use smaller traces (0.13u vs 0.18u) and run at lower vcore. They are cooler, draw less power, and would be easier to overclock from that standpoint. My next cpu will be an XP2700+, since I'm looking for native 166mHz fsb support.

The XP processors (Palomino) ratings were based on a comparison to the Thunderbirds. So an XP1600+ (1400mhz) has the performance (roughly) of a T-Bird running at 1600mhz. So they say. But it also allowed AMD to print bigger numbers, since Intel basically baits the consumer with big numbers. The average consumer will not understand how this all works, all they care about are big numbers and key words such as BLAZING, AWESOME and PERFORMANCE etc preferably in combo with one another. Suckers. But I've begun to change the subject.;)

MPs overclock just as well as XPs, they just come unlocked from the factory. You decide if that's worth $30.
The best XP overclocker would be a palimino xp1600 (cheap) or a TBred Rev 2 when they come out.

For cheap thrills, the AGOIA 1600+ Palomino. An AIUCB 1800+ T-Bred/B if you can find one. I haven't been able to...

What is the standard voltage of an XP? How far is it generally safe to up it? Any of you guys overclocking with a standard HS/fan?

The Palomino XPs are 1.75vcore default, the TBreds are 1.65vcore default. Consensus seems to be 1.85 is quite safe for a Palomino (assuming a good HS/fan)... my take would be +0.10v on the TBreds, too. I've run TBirds and Palominos essentially 24/7 at +0.10. Some folks push to +.015 and even higher with really good aircooling (incl really noisy, high rpm fans), or water cooling. Personally, I would not consider an overclock with the retail HS/fan.
