Lowering temps of core

[Guest]

Archived from groups: alt.comp.hardware.overclocking.amd (More info?)

as spring temps rise, have noticed a slight increase in core temp. Should
temps start encroaching the 60 degree range, which would be a better way to
lower temps. (don't want to do hardware mods)
2500 barton running stock 1.65v 200fsb and 11 multiplier sits at 48 idle,
52-53 loaded.

lowering the multiplier alone
lowering fsb
combination of voltage and above?
Just wondering at this point.
Thanks

I've been playing around with undervolting my XP2500 Barton and have
210FSBx10 Prime95 stable using 1.55v. The max temp is 44C as opposed to 50C
when it was running 220FSBx10 using 1.725v. Of course your mileage may vary
;-) I'd say see how low you can go set to 1.5v or 1.55v (try 200x10). Post
your results.

Total waste of time since it will run just fine at at least 85C.

Maybe yours will - but mine won't (Barton 2500+ @ 2400mhz at 1.9v vcore)
if the core temperature gets up to 55C under full load - I start getting
errors in prime95 and games will crash, whereas under 55C - no errors. It
seems my cpu can get a lot hotter if I wuss about with marginal overclocks
(eg 2200mhz) or no overclock, but to get the maximum out of it I have to
keep it cool.

This is a completely untrue, though a common misconception. A
non-overclocked CPU might well run fine at 85C. As soon as you start
overclocking then all bets are off. It could crash at 41.... or 59... or
85. But at 85, you can be pretty certain it will fail. At 41, its more
likely going to be OK.

"Of course your mileage may vary". I think you got it right there Frank.

Most 2500's I have seen need more than stock volts to do 3200 speeds.
There's no way the *average* 2500 will do 2100 at 1.55. I think you got
lucky.

My barton 2500 is running as a 3200 Only alteration on an Asus A7N8x-dlx
was setting fsb to 200 Temps are ~47C under normal load, and ~55C doing
this or that, not max loading though..

Mind you I did get an early one Before the locking situation arose.

There seem to quite a few variables with the 2500, not just the cpu
itself, mobo, memory etc can alter the situation... horses for courses
in the end I guess

So far I've OC one way or another damm near every AMD cpu
I've had and only had 1 out of 9 die on me, and that was down
to the cpu fan running intermittantly:-/ Damm thing ran on startup
and could be seem and heard running then it would stop for no
apparent reason sometime later.. I only found the problem when
the cpu croaked:-( That was an XP1800+... working as 2200+

That made cooling the cpu a major item for me And MBM
sits on the dashboard with the cpu temp highlighted in red on
a yellow background...and I watch it, at least when I'm awake
All my rigs work 24/7... so some of the time they are on their
own... which I suppose is the way its supposed to be

I bought my XP2500 (AXDA2500DKV4D / AQXEA0324TPFW) on eBay when it was
discovered that AMD was locking the multipliers. I'm sure if it was locked
at x11 I'd have to run much higher voltage to get up there. And then heat
and stability become much more of a problem :-( I've got a 0330 that should
be here soon. I'll replace my unlocked XP2600 T'bred and see what it can do
in my backup machine ;-)

Hi RD,

I am not saying that Frank's experience is unique. Clearly many people have
had good successes overclocking and especially with the 2500+ Bartons. My
only point is that its not the *norm* for 2500+s to do 3200+ speed at stock
volts. Some will, but many - probably the majority imho - will not. I
think most need an extra 0.025 or 0.05v. Maybe a little more.

Therefore to ask these chips to do 2100MHz or even 2000MHz at only 1.55v is
asking a lot, I think.

Cheers,

Chip.

I havent had more than one to play with So I cant really say for sure
either
way from personal experience, but it seems logical that a 2500 will go it
wee
bit more then need more umph in the form of a higher vge.

Horses for courses The best way to find out is to try, start low and work
up
