Pinmod (voltage) on Duron 1800MHz

Wes Newell was interested if voltage can be modified through BIOS after
doing pinmod for voltage, the answer is yes

I had some free time so I used pinmod to modify the voltage on which my CPU
runs. It ran on 1.5V default and I could increase it by 10% through BIOS but
for 13.5x166 it wasn't enough . I used voltage pinmod and I set voltage to
1.7V. And increased it by 10% through BIOS (yes, , it works) and my
computer was stable, it entered the windows and I ran Prime 95 for maybe 5
minutes and then it hit 70C (my MBO is Gigabyte S7S48) so I decided to work
on 13.5x156MHz=2106MHz where I do not need voltage pinmod and it runs much
cooler.

Now I'm saving for watercooling and then it will go to 13.5x166 , maybe
even more, I will see. And after that peltier will join the watercooling kit
for some extreme OCing

Thanks, I wasn't sure. and I'm too lazy to test mine.:-)

What cooler do you have now? Are you sure it's on right. That sounds very
high, but I don't think you need water to cool it down. I've run at
2400MHz with just a cheap $8 cooler.

np , I was curious also

I have Spire Whisperrock IV, the case is AOpen A600A with a 120mm in the
back (I run it at lowest setting, didn't see any diffirence in cooling on
low/med/high settings except for the noise . The airflow is ofcourse much
greater at high but no temperature drop. Cooler in the front is going to
wait a little bit cause in my city (small ) there are no 92mm ventilators
to buy.

Maybe the temperature was to high coz I didn't have any thermal paste (I
have Titan, heard it's not too good so I'll get some Arctic Silver 5 later).
When I removed the pinmod, I reapplied the thermal paste and now I think the
temperatures are a lot lower (10C). Will test it later

What about Spire Whisperrock IV? Any good? Should I get different vent (more
airflow) for the Whisperrock and leave the passive part or should I change
the cooler? You ran Duron 1800 on 2400? What about temperatures, what MBO?

Yep. No thermal compund will definately cause high temps. It will probably
be closer to 20C lower now under load.

Same HS as the Falconrock II from what I read. OK, but a fan that puts out
a little more air will help if you need more cooling.

The cooler should be fine as long as you use thermal paste and don't
install it backwards. Stronger fan would provide more cooling. The basic
HS construction is Ok.

You ran Duron 1800 on 2400?

Well, it wasn't a Duron 1800, but it was the same core, Tbred B, CPUID
681.

What about temperatures, what MBO?

I think it topped out around mid 50's without software cooling, Ran it on
the board below, and also on a couple of K7S8X's. Only had vcore at 1.80.
Could probably get a little more out of it if I tried. Still got it in the
K7S8X R3 at 2700+ (13*166) speeds, but it's just my spare now. Currently
using an AMD 64 with a S755MAX MB.

Hello everyone how you doing.

Just a general observation on the Applrebreds.

I think I struck lucky with the Applebreds. I got me an unlocked 1800
with an Asrock K7S8XE + cooler for £64, and this was at the time when
these Duron's were just coming out.

Despite only having +5% Vcore on the Asrock (i.e. 1.58v) and using a
thermal pad, I can hit 2150MHz using a standard cooler. System runs
United Devices all day and never locks and the only lockups I have are
with Win98se or speeds over the 2.2GHz "wall". Intel people ask what
all the fuss is about - they seem to forget the "PR" rating! Friends
have bought £700 Celeron/Pentium 4 setups and this Duron rig seems so
much better.

Only thing I would say - get a fast grafix card if you're overclocking
to make those games run faster. I use GF4 Ti 4200 and notice that
whenever lens flares or fog appear in Direct-X games, the frame rate
plummets as these FX are emulated in software instead of being
processed by the card itself (i.e. LOTR: Return of the King). No amount
of MHz or bus speed can counter this, although I am not sure how much
the lower L2 cache contributes to the effect.

The system has "burned" in enough now, and I am ready to get under the
hood and take back my L2 cache as well as mod the Vcore or even use a
better overlocking board.

These Duron's rock :-)
