I had an Athlon XP 2600+ (Barton) 1,65 V, 1919 MHz stock. I hit a wall with ther motherboard (Asus A7N8X-E) at 1,85 V and 2557 MHz. The performance was great, I think that it was actualy way better than my Athlon 64 3000+ stock (1.8 GHz). I used a ThermalTake Volcano 12. It´s surely loud, but it cools it like a champion.
Of course, with higher clocks models I don´t know what could happen... surely mi Venice at 2500 MHz is faster.

I have a xp 3200 how high do you think i can oc it too?
 
Ebay, but a good nforce2 board still cost around $40. I just sold a MSI delta
that didn't boot as-is for $24, I couldn't believe it. It seems 2.4 was the average OC for the burton core on air.
Not to change the subject, but I'm I the only one who wants to see the burtons on a 65nm die with 1mb cash and updated extensions? Some tweaks to the core and it would be a nice 32bit chip. Intle went back to the p3s for there new chips after all. Just the clock increase would be something.
 
They're Bartons not Burtons but you're correct about needing a good NF2 board. Something like the Abit NF7-S V2.0 or an Epox 8RDA+.

dvdpiddy, the 3200s are/were the top of the line for the XP series. I'm not sure how much headroom is left on them since they are the fastest stock Athlon XPs to be sent out. What are the idle temps at and at what voltage? Stock was at 1.65V.
 
My XP 2800+ Barton will OC to 2.75 on air, but not very stable at all. It's stable at 2.55, but runs really hot (83c, yikes!!) 2.24 is about my sweet spot, totally stable at 53c under load.

LET ME SEE *CHECKING ASUS PROBE* 35c!
 
Thanks man its an awesome site! But how high do you think i can get my xp3200 to i was hoping fx-55 speeds and dude i aint using stock fan i am using the thermaltake volcano 10+ i bought my cpu oem thats why so how high do you think i can take it i got 2.5 ghz before but it kept overheating thats why i got as5 now so the sky's the limit right?

Is there attitude along with this? Because I was just trying to help.
 
I'm having some problems with my Athlon XP 2500+ Barton.
Vcore1: 1.63V
Vcore2: 1.55V
FSB: 165Mhz X 11x = 1815Mhz
RAM: Kingston Value Ram --- 512MB CL 3 --- KVR400X64C3A/512
Mainboard: ASUS A7N8X-VM (NO BIOS Settings. No voltage FSB or Multiplier)
PSU: ANS 400W

When I raise the FSB, using SpeedFan, to 189Mhz (2079Mhz) is is perfectly Stable and Benchmarkable :) (4000 score in CPUMark 2.1).
When I raise it from 189Mhz to 190Mhz it instantly restarts 8O :x .
Temp.: 55 C

What should I do to get higher performance?

That mobo probably does'nt switch from the FSB/5 to the FSB/6 divider, causing your PCI & AGP bus to respectively run at 38MHz & 76MHz when you set the FSB to 190.

Without a way to change the multiplier and voltage in BIOS, you'll have to use a wire mod to force the proper settings by tricking that POS into believing that you got a 200MHz FSB CPU like a 3200+.
 
:lol:

You said you were running an Asus board. Which one?

What are your CPU/RAM/Chipset voltages? Chipset probably isn't adjustable on your board, but I thought I'd ask anyway.

What brand/speed is your memory and what are you running the timings at?

I ran into issues OC my XP-M 2600 because I had nothing but cheap value ram, but I was still able to achieve 2.4 on air rather easily. If you have good RAM you might be able to achieve a decent OC but 2.6 is really pushing it for a chip that is already at the top of the Athlon XP charts.



Dan14, from what I've read that board supports virtually no OC abilities.

If you feel adventurous enough, you can try Sid's wire mod.

You're probably reaching the limits of that Value Ram. You could try getting a better quality RAM as well, but I don't think it's worth it. Your board just wasn't meant to overclock processors.
 
I have a 3000+ (barton) with 13x multi, and I can run at a FSB of 186, 2418MHz, but as soon as I hit 187FSB then i currupt the OS. Will take that off stock volt, and overvolted, even if i slacken off the RAM timings, and put the RAM at 1:1 to CPU.

One day soon I will Ghost my drive, and play some more, but i got pissed off with having to reinstall XP, not that it didnt need it mind. at 186*13 its cold as on stock heatsink and paste. If i can get the thing to run at ~200Mhz on the FSB then I will upgrade the HFS, and get AS5 on it.

Motherboard Asus A7V800 (Nasty VIA chipset)
2*512Mb DDR Crucial Midrange RAM.
 
Do post and tell us how it went.

And i dont think that there is much headroom on the 3200+ because of the 200FSB. May not be stable, and u may have to fiddle with the CPU:RAM ratio to keep ur RAM happy. Best of british though.
 
My bad, Burtons the next town over form me[ then flint :cry: ].
SidVicious is right without a pci/agp lock you wouldn't go to far. You could look for a modded bios and open up some features but the nforce2 is a legend and is the only k7 chipset worth a crap IMO.
I ran my unlocked 2500@ 2.13gh[ on stock air, no overvolting] with no prob in a MSI delta nf2 but in a ECS board[ also nf2] it wouln't go past 1.9gh. The ECS had a good chipset but nothing to support it. That 2500 is running to this day in my father in laws system[ MSI dealt2 ] at 2.06gh with a 9700pro and 1g ddr400. Plays doom3 like a champ. I would have pushed it further but it was the only system I had at the time and my girl friend needed it for on line classes.
 
252x10. Take it your on about the highest FSB not total speed there? If so then there aint a chance in hell, but if your on about the highest GHz then I may have to try and challlenge that.

Can the multi's be lowered on a 3000+ Barton, or is it locked at 13x, and thats all it will give?
 
Yeh, but that with custom waterccoling plus ice chilled water on 1.975V
Just for the sake of Bungholiomarks and all that. 8)

At least it reached into the top10 table of 'normal' Barton records which is what I wanted.

Ahh, yes...you aren't anybody around here unless your equipment is Bungholiomark© certified.

I searched both Google and my CD book of the Da Vinci Code and could not find a source for Bungholiomark. Please provide a link.

Looks like XP overclocking did a lot to get people into their BIOS.
What a blast from the past this discussion is. This old rig just putts
along year after year. XP2500/AbitNF7 v.2/Value RAM 11x200

The ultimate limitations for the future is simply, clockspeed isn't
everything and pushing much over these speeds you run into
video card issues and lots of parts running hot. Also I don't think
NF2 has much future.I think these are great setups for anyone
wanting to learn a lot, but I would always recommend a good
939, and if you haven't tried it dual core,
you will never go back believe me :)
 
It's all about money for me, I can build socket A stuff cheaply, just have to keep your eyes open for the deals. That and the fact that I'm running games like Fear at high framerates and resolution on this old timer is really cool.
 
I just bought a DFI Lanparty NF2 Ultra B, and it's certainly seemed to breathe some new(old?) life into my system. While I was moving my processor from the old Mobo to te new one, I couldn't help but notice the year my 2500+ was labeled: 1999. Wow. How times have changed.
