My nice overclock (Barton 2500)

[peterwilkes]

Just wanted to let you know that I have overclocked my PC for the very first time and so far I am happy!

I upped the FSB to 200 Mhz and the multiplyer to 10.5 x so that gives a speed of 2100 Mhz at 1.75 volts (1.6v standard)

I am getting good temps so far as shown below.

Before overclock (stock speeds)

Idle - 38 deg C
Full Load (prime95) - 42 deg C

After overclock

Idle - 43 deg C
Full Load (prime95) - 46 deg

This is with complet stability according to a 3 hour run with prime 95 and a 3 hour run on 3D Mark 2001 SE.

I am using a ThermalTake Volcano 11 Xaser Edition set to the lowest speeds which is about 1700rpm and a room temp of 20.5 deg C.

I am pretty please with how this has all gone, especially that the CPu has not got that much hotter

Let me know what you think! I wont be pusing it up to 2.7 Ghz just yet well, not without some serious cooling anyway. LOL

Cool. Good to read this. I'll be getting a B2500+ shortly. I'm still stuck with a Volcano 7, unfortunately. But with results like that, I may have to invest in something a little more modern.

I just got one too! How much do you guys think I could overclock it with the stock heatsink and fan? Could I get it to 2000mhz maybe.... or should I not even try with the stock hsf.

[peterwilkes]

I am not too familliar with the stock heatsink and fan. If you post me the idle / load temps plus the room temp I can let you know roughly how much to expect.

If you can keep a processor cool enough, and the voltage high enough, there shoulkd be no probs getting 2.2 or even 2.3 ghz out of it.

I could have gone to 2.2 ghx (XP3200+) but that would have meant turning the fan up a little which I did not want to do because of the noise.

keep it up, im sure you'll get higher..

i have my 2500+ anywhere between 2300 and 2400MHz depending on the time of year/temp. Ive sailed up to 2500MHz with it, but it got hot pretty bad, id have to get a water setup for that, and its just not worth it at that point.

i use a lapped SLK 800 though, which really helps a lot. If you're getting an SLK you really should lap it just because it come really rough on the bottom.

Wow, super easy stuff!

My Barton 2500 runs stable at bus 194mhz... got BSOD at 200 though.

Effective WCPUID says 2136 mhz.

No changes to voltage or multiplier, running on stock AMD cooler!
(med load @ 43C)

This is a MSI K7N2G-ILSR, running integrated video.

But this is Samsung memory rated @ PC2700, so I'm pretty happy.

Maybe I'll lap my cooler and try a slight bump in voltage...

but right now I practically have a 3200 barton, for $79!

woohoo!

[peterwilkes]

It's amazing that my barton running at 2190 Mhz beats the hell out of a P4 3200 Mhz CPU even with a whole 1000 mhz seperation.

Max load tests usually get the CPU up to 50 deg C which is at 23 deg C room temp. I do not think that is too bad concidering that the Volcano 11 is runing at the lowest speed (1700rpm)

Thats only a 27 deg Increase over room temp. At stock speeds and voltages, there is about a 20 degree increase.

[zucchiniman]

OH NOOOO!

I got too excited too quickly, didn't run a burn-in cycle yet, then the kids used it and BAM a freeze-up followed by bad disk corruption.

(at boot time the system claims it cannot find windows\system32\config\system which is the system registry hive - yikes! this will take me hours and probably a repair-reinstall to fix!)

Took it way down to 175mhz and I'll have to clean up the mess.... if I had to guess either the bus flakes out or my cheapo memory can't handle the load.

I suppose there's no safe way to test your overclocks, is there?

I had always assumed that a crash wouldn't trash anything but the current session.

Does it help to turn off drive caching and run burn-in cycles, or are you always at risk of data loss if you get flaky?

Does it help (i.e. prove anything) to run one of those boot-time memory stress tests?

Thanks!

try 11x multiplier (or 11.5) and up the voltage to 1.85
my 2500 runs 2.3 (200 x 11.5) running at about the same temps

Guys, I am getting a barton 2500+ and plan to push fsb to 200*2, while leaving multi at 11 and vcore at 1.65
I don't want to change vcore, because i don't want to kill proc life. How much life is lost when vcore is changed to 1.7? 1.75? 1.8? etc.

Thanks
