Barton 2500 - mini-success story.

[alm]

I wrote a few days ago that I'd return and let you know my success story... this is my very first overclock for AMD....

Abit NF7(non-s) latest bios.

Kingston HyperX PC3200 (non-A) (512MB Kit)
I believe they are BH-5 Chips??!!??
Running CAS2 2-2-11 for memory timings... no hiccups!
Actually pushed to 217FSB @ those timings.. booted no prob.
Running 2.7v for mem voltage.

Barton 2500+ 0340 SPMW - Unlocked (verified) Running 1.7v

Running 11x200 - 33c Idle 43.5c Max (Under Prime95)
Ran Prime95 12 hours last night - no lockups!

Not sure if I should step the multiplier up to 11.5x or just be happy with what I have! It's very quick as it is now!

Thanks to HOOT, and a few others that helped me out.
Excellent forum!

could u post the rest of ur specs in ur sig or this thread?

becuase i think the 33 idle and 43 load is a bit off...especially if u have good cooling, bartons are supposed to run cooler than t-breds...so i dont know whats up w/ that. But then again...abit's have been known for reallty off temp readings

Well if that is BH-5 you can probably put the memory voltage all the way up (2.8v right?), they have been know to run great at 3.2v even. 2-2-11 isn't all that great, you might see more speed from lower timings on that last bit if having it at 11 only gave a few mhz...

I say lower the fsb a lil (so it's at the same speed or about the same speed as it is now once you do step up the multi) and step it up then raise the multi slowly and test away

On an NF7, it is not unusual for the Vdimm to be a full .1V higher than called for in the bios. I think manufacturers err to the high side just to make sure it is not undervolted. On my A7N8X, it was .05V high. So, even though you are calling for 2.7V in the bios, you may be running at 2.8V already. With speeds similar to yours, it takes me 2.8Vdimm(real) to run stable at 11x200 2-2-2-11, so it would not surprise me if you measured your Dimm switching mosfet and found the voltage to be closer to 2.8.

I can punch mine easily up to 11.5x200 with 1.75Vcore, or 11x210 with 1.9Vdimm(real), but the system as a whole, feels more stable at FSB of 200. Don't ask me to qualify that one.

bartons run hotter than tb the larger on die cache generates more heat.at the same clock all my bartons with the same cooling
and mobos ran 5-10c hotter than the 2100 in the same rigs.

 

[dalilman52]

but dont the bartons have a larger die size?

Actually I am pretty sure they are the same... but even if it does it's not enough to make up for the extra heat generated by the extra cache.

 

[dalilman52]

ic...thx for clearing that up

My Barton runs cooler than the XP1800 I'm playing with now at the same voltage. YMMV

My barton runs significantly cooler than my tbred did. Maybe I got lucky

visually it looks about 1/3 bigger havent measured.unfortunately
the larger die doesnt transfer heat as fast as you would expect.

my barton at that same week runs cool too but it does 2380 at stock voltages,at [email protected] its about equal to the thorobred
at 2480-2500+ it spikes to 64C,i dont run water so 2420 is where i stay 24/7.my thorobred never breaks 55C at max oc prime 95
not even at [email protected] my duron 1600 based on the TB
needs 1.9vcore to run 2350 but never breaks 48C on air with the
speeze 3200 cooler @2250 rpm/28.5 cfs
