A7N8X-E Deluxe and OC'ing, Question about 1.8v cpu core

Ok I got an athlon 2500+ (i think 1.86ghz stock) running at 2.3ghz rock
solid stable at 1.775v.. cpu is 54C under max load of prime95 and 3dmark
2001 SE running 24h.

the chip works just fine at 2.4ghz at 1.775v as well, but I generally get a
crash after about 8h. I'm thinking of pushing the chip to 1.8v.. but the
cooler I have, a thermoengine with a delta 38CFM 60mm fan, is probably not
going to do the trick.

Should I be concerned with pushing the chip to 1.8v (or perhaps even 1.825,
or 1.85v) ?

Also, my mem timings are currently 2-3-3-6. I'm going to tighten it up to
2-3-2-6 soon (HyperX PC3200 ram)... this shouldn't have any adverse effects,
yes?

I'm even thinking of pushing it to 2.5ghz with a higher voltage (1.8-1.85),
but thinking the new cooler I ordered just won't cut it. Its a zalman
cooler, I think its a Zalman CNPS7000A-Cu (92mm fan on it). I got this
cooler because its a much more quiet cooling solution then my current setup
(60mm delta fan/thermoengine).

The key here however is that i have a rock solid system, as it will be used
for graphics design.

ANY comments/help would be appreciated.

Well it's been said heat kills hardware, so the cooler you can keep an
over clocked CPU the better off you'll be.

The Barton 2500+ runs at 1833MHz, sounds like you have a decent core! My
week 7 Barton 2800+ (2083MHz) will only do 2378MHz @ 1.80v stable, more
vcore really doesn't help it either, best I could do was 2400 but was no
where near 100% stable, I just have a Vantec Aeroflow on mine so I just
run it at 2315MHz @ 1.75v.

I lost my last partition on my slave HDD in WinXP playing with ram
timings, had to use DOS to get the files, in Windows the partition was
blank and would say... want to format this drive?, so you may want to
Ghost your HDD to a HDD/DVD/CD before you leap tooooo far! ;p

Good luck,
Ed
 
Well it WAS rock solid at 2.4ghz the other day at 1.775v, but ti seems like
the shit hit the fan... because at 2.2ghz its not stable anymore?

I think it may be due to the fact that when i was testing it the other day I
had the window wide open, and its 20F outside here in canada, so it kept the
room at a decent temperature.. but with the window closed today, the CPU
core shot up to 54-56C and that was the breaking point.

I'm back down to 2ghz right now trying to ensure it wasn't norton internet
security prof 2004 that caused the crashes today, since I just installed it.
(I would of thought playing 10 hours of call of duty would bring my system
to its knees, but apparently 15 minutes of C&C generals zero hour was much
more stressful on the system, who knows lol)

54-56C die temp shouldn't really be a bother for an AMD CPU , mine was
hitting 65C at full load this past summer , socket temp is generally
10C-12C lower then the die temps.

It's cool here now too, my PC room only gets up to about 23C, CPU die
might get to 55C at full load, playing games it peeks at about 52C. But
how accurate these readings really are is anyone guess!

Best of luck,
Ed
