How great were Athlon Thoroughbred CPU's for O/C'ing?

A friend has an Athlon 1700+ thoroughbred for sale with an Epox EP-8K3A and I'm seriously considering buying it since he's offering it up at a super low price. The combo would include a Thermaltake Volcano 5 HSF.

From what I've read most of the Tbred's overclock a good 700Mhz straight out the box with maybe a +.1vcore adjustment, is this true?

I know this setup is outdated but I'm low on cash and my system (T-bird 750 @ 1Ghz w/ Abit KT7) is older than the trees.

Has anyone else had experience overclocking thoroughbred CPU's to a decent speed? What's a realistic overclock with this setup, 2Ghz?

Also I plan on using PC3200 RAM so that I can jack the memory and FSB up higher. From the reviews on the net the 8K3A seems like it was a great overclocker.
 
The old $44 1700+ Tbred B's were supposed to be quite good overclockers, so try it if the board is good.
 
The 1700+ Tbred is generally a good overclocking chip. I know you said you were short on cash, but have you considered getting one of the 2400+ mobile chips? You could probably pick one up pretty cheap off the FS/FT forum, since everyone is moving to the newer A64 chips.
 
The Tbred 'B' was not bad at all. My 2100+ runs at 2.25GHz (2800+) at 1.7V. Bear in mind the chip was made in the first few weeks of 2002. In contrast with the mobile XP-M's that became the OC craze in mid 2003, this was not bad at all.

The Tbred 'A' core was not as nice. The OC's were about 2GHz tops on air. The 1700+ was produced in both flavours.
 
I have a TBred-A XP1800 unlocked retail CPU that won't go past ~1.7Ghz stable, but my mobo won't let me give it more than 0.1v above the default of 1.5v either. XP2200 and up nominal voltage is 1.65v.

OTOH, I built a rig for someone a year later with a TBred-B XP2000 locked retail CPU, and I was able to clock it pretty high on an Biostar NF2-based board just by upping the FSB, I had the BIOS showing XP2900+, don't recall what the actual Mhz was.

So in short, TBred-A = poor OC'er, TBred-B = excellent OC'er. (And a 1.5v TBred-B = mindblowing OC'er, assuming your mobo isn't limited in adjusting vcore like my MSI KT400 board is. 🙁 )

PS. Even if the chip you get doesn't overclock by much - it's still going to be nearly twice as fast as your old rig, which was probably running SDR too.
 
I've had experience with a 2100+XP and two 2200+mobile XPs, all three were TBredB. Without insane voltages, the 2100+ desktop cpu was good for around 2.2ish and the two mobiles were good for 2.3ish.
 
My 1700 JIUHB did 2.42 on my AN35N. Currently at 2.3x on someone else's other board.

:brokenheart: to see it go, but at least it went to a good home.

What's a quick way to determine which of the two a given cpu is? If the A and B are that different from each other, I hope there is more than just a code for production week to go by? I'm about to build a PC for a grandkid, and I have a feeling that other grandkids are going to want to know when he/ she will get one of his/her own. I think that XP's make good starter systems, and presumed that I might pay the extra to get Bartons. This thread gives me some reason to think more about that plan.

Overclockers.com had a pretty definitive guide to identifying XPs. Btw, there is also something else to think about, most of the later-model chips, including the non-mobile Bartons, had locked multipliers. So the only way to (safely) overclock those is by increasing the FSB, which generally requires an NF2-based mobo, which has async PCI/AGP/CPU clock speeds. (The so-called but incorrectly-termed "PCI/AGP lock" feature.) Mobile Athlons are by definition unlocked, because they are able to adjust their multipliers on-the-fly for power-management purposes. Which is why they are more valuable for desktop users looking to overclock too.
 
Best chip of all time. $44 LOL and still screems. Heck back then you could build mobo, chip and 512MB ram for a what a 2.26B costed by itself. Many OC to 2.6..I only got 2.2 and am very sad I sold her.🙁

I was thinking about using a micro ATX MB from MSI, in an NF2 series they sell -- that link was just what I needed; voltage differences in the OPN --

Thanks! 🙂
