1.2 Tualitan- how many volts is too many?

Uncle Vinnie wrote:

Well, I'm now working on various settings from 1.4 to 1.6, nothing stable
yet.

Somewhere I read about possible heat issues with this board. I have the fan
from the powersupply pulling air out of the box. I have added a fan to the
front of the box (that is where Pionex placed the mounting), which pulls air
into the box. I have an oversized Intel Heatsink/fan on the CPU. Temps are
111 for processor and 99 for board area....

I hope you mean F.


Nothing seems out of the ordinary.... running with a 250 powersupply.
Again, all runs solid with the 800 piii....

Will keep tinkering...

David- I think you might have nailed it!

I swapped out Power Supplies yesterday, on a whim (the HD wouldn't spin). I
had a 230, and tried once before with a 250, which must be why it crapped
out.

I got a 330 Antec from CompUSA and all seems to be running solid...(I also
found one a 380 RaidMax at NewEgg which will come down to $8.00 after
rebate).

That might be the issue all along...

If it continues to run solidl, I will attempt the Upgradware again, but for
now, all is fine.

Jumper setting at 1.55, Vcore at about 1.527.

And yes, temp is in F!

Odd, my Compaq has a similar PS and it runs all the same stuff...

Super. I'm glad you got it working.

Might as well try the stock voltage again too.

Well, not all power supplies of the same rating are the same, especially if
all your looking at is total watts, and neither are motherboards, power
wise I mean.

Just as a side note, one of my BH6s is on a 250 watt supply as well.

I say try it at 1.7v and the 133 MHz bus setting! Might run 1.6 Ghz...

Since he hadn't been able to get it stable at ALL it's best to first
establish an operational baseline.

Yes, and yes!

I am running it over the next few days set at 1.55 (vcore at 1.527).

If it was the PS all along (which it might be, and since my first attempt
was to replace a 230 with 250- which probably meant my PS wasn't bad but
that 230 or even 250 just wasn't enough), I will then crank it up a little
and see what happens!

However, if anyone needs a cranked up PC, that would be me....

That will wait a week... (I have a Compaq 5000T/ 5BW. Motherboard believed
to be actually Mitac 6513WU.

Here, I might lead into the same problem... The stock PS is well 300...
could be around 230... I need to check, and feeding more voltage might put
more of a drain wouldn't it??


Thank you both for all your help... As soon as all settles in, I will post
a huge thank you... you''ve helped alot....

My Abit BF6 is currently running a Tualatin Celeron 1.1A at 139 x 11
(which is all my memory will do 2-2-2 with the three slots filled) at
1.65v. It ran 143 x 11 with just two sticks of memory, though. It's nice
to be able to make the small adjustments. It is powered by a 230 watt
Powman that came with the Inwin case. It is cooled by a physically
cut-down and slowed-down Cu-Al HSF that came stock on my
Athlon XP 2500+. I bought a 1.2 Celeron (also 12x multiplier) on
eBay for my mom's computer, and quickly checked to see if it would
run at 133 Mhz on my board. No luck!

Amazing...

BTW, that is the PS I am replacing, 230 Powerman.... to a 380 raidmax I got
at New Egg for $8 after shipping and rebate.

I was going to put it into my Compaq, but am checking to see first, how my
Compaq can only be running on 145W (per the part), with a 1.2 Tualatin,
adapter, 512meg, DVD, CDRW, 40G HD, floppy, firewire, modem, NIC, and 4
usb's all used...

The idea would be, if all does run fine on my daughter's pc, she gets the
upgradware adapter back, I get the LinLin. I then move the voltage up a tad.

If I do get it to 1.65 or 1.7 as you mention, what would the 1.2 actually be
running at?? AND, remember, this board runs 133 FSB, but 100 speed mem..
(verified by Mitac- odd isn't it?)

Thanks!

Mitac did a number of boards for Compaq. I've got one I picked up as a
replacement for an HP motherboard.

I bet you noticed that Compaq isn't HP. So did I after it got here but the
fly by night *&%$ who sold it didn't.

I bought it back when the tualatin mod was a hand wiring job and was going
to use it to test for a customer's HP and it was supposed to BE the HP
mobo. I had my own tualatin to test with and he agreed to pay for the mobo
(it was very cheap) to run it on so if it worked I would swap boards and
the customer got a tualatin plus I got his board for a 'spare' (and paid
for the work). If it didn't I ended up with the new board as a 'spare'.

As my perfect 'all bases covered' plan turned out I had to eat it because I
couldn't run the test. One of those "best laid plans of mice and men..."
things.

Power consumption increase linearly with speed but with the square of the
voltage, which is why increasing voltage is the last thing you want to do.
When overclocking you increase speed first and voltage only if needed and
only as little as needed because it's working both for you (volts for
stability) and against you (heat generation). And the 'against you' part
gets bad faster than the good it's doing real quick.


Thank you both for all your help... As soon as all settles in, I will post

Thanks David..

Actually, this PC is a Compaq- it's coming up on 5 years old. I've taken it
about as far as it can go...

I was thinking of boosting speed a little by upping the voltage (per
Fishface) but as it is, it is very stable, unless I keep it running without
AC!
(It's in my office, a converted attic- Without the AC on, the attic probably
hits 110/120F! PLUS if I forget to keep the desk cabinet open that it's
in!)

My first idea was to replace the power supply since, per the part number,
it's only 145 watts (how can that be?). I was going to take the 230w
Powerman from my daughter's Intel (being replaced with a 380), and use it.

BUT, I am not sure of 2 things- first, how can the Compaq p/s be only 145w?
Second, is it a standard ATX p/s?

The board, btw, is a Mitac 6513wu, with Compaq's part number 191767. The p/s
is Compaq p/n 124848.
