Vcore is 1.88v with wire trick, what should clock multiplier/Cpu freq be to suit?

2000+ XP Tbred 'A'
1.88v is my vcore (applied with the wire trick) as I have a Asus
a7s333 board.
I havent tried any other varients of voltage, because its quite tricky
to apply and this voltage was the "easiest" to attempt as it only
required wrapping wire around 4 of the cpu pins as a "whole" and seems
to apply/work reasonably ok.

I have noticed some instability anywhere approaching 1900Mhz
thereabouts so have clocked it down.
However as I dont have a very good case design at moment, the temps
can rise so I think it has been 45c lately but I am going to monitor
to get a mean value.

Q1/ Can anyone suggest, since I was able I think to run sort of
1800Mhzish at 1.65 vcore, what a "good" value for cpu frequency is to
take advantage of the 1.88v without running too high?
Obviously its some 0.23v higher than standard vcore, so am I best to
leave it overclocked by around 200Mhz say 1850Mhz (12.5x148) and look
at sorting out my cooling?
Or should I be very afraid and remove the wire trick, and try running
lower at normal vcore

Q2/ Also should I be opting for the huge "silent" coolermaster 3200+
rated cheapo cooler or is it going to do little that my existing &
reasonably meaty cheapo coolermaster 3000 rated job does.

Many thanks yet again for any interest in my ongoing oc newbile
attempts :

Unexpected voltage may be because of unmodified L11 bridges, however I went
for 1.85v and got it without touching L11.

if that is the cpu temp under load I would not worry too much

This is where individual wires in each pair of holes has an advantage -
easier modification.

Running too high is a relative term, to me too high is unstable, many
systems in many situations will fall over long before they break. The
problem with high vcore is heat.

On 1.85v vcore I could get my (1.5v) T'bred A 1800+ to run and bench mark at
11.5 x 172 (1978MHz) but was not long term stable. So I settled on 11.5 x
167 (1920MHz).

Perhaps you should find out about any other bios settings you may have, such
as CAS, memory timing and see if they can improve your settings. But it may
be other things causing instability.

If your exhaust ports at the rear of the ebuyer case have slats across them,
block the bottom one off and get a pair of side cutters, or something and
cut off all of the slats from the top hole and dramatically increase the
ability to blow hot air out of the case with the 80mm fan. Removing the
slats from the top hole (in the summer) brought down my cpu temp by 3C and
case temp 2C.

Hi Paul
Done already and now im on a constant 40c cpu and 25c case on idle I
actually took pliers to the slats off before Id even read this, but thanks a
lot for all the advice especially OCing Mind you window has been open and
it is quite cool this evening. Im definitely running 1825 Mhz reliably so
Ill have to see about higher frequencies now I have cooler temps.

Those dumb cheapo case designs really suck. Mind you compared the AOpen case
I have (seems much better from substantiallity point of view) however it
doesnt have the twin exhaust case mount point like this modern style case,
or frontside usb headers so cant be that bad.

It may be that the A core 1.65v DKT3C processors have the commonly reported
low-mid 1800MHZ ceiling, whereas the 1.5v DLT3C processors can go a bit
further. I do not have any information on this but I am just wondering if
it might be so.

Have you tried dropping the multiplier right down and seeing how fast the
fsb will go. Then bring the multiplier up until it is not stable then
started trying to fine tune it around that point.

If it does have the low/mid 1800 ceiling, you may be able to drop the vcore
a bit and still get it to run.

yeah - cheap and nasty comes to mind. Still they are fine for normal use,
and I could OC the A core on mine quite happily, - it was only when I
seriously tried to OC a Barton in there that I killed the psu
