Max clock, AIR cooler, 1.6V, no mods, old BH-5.

Stable clock:

1.536v is about the standard voltage most people seem to get with a non-droop modded board with 1.6v set in bios..

:bs:

on P4GPL-X it overvolts if you set voltage to more/equal to 1.4V in BIOS.

yes, imo thats one of the biggest issues of those asus s478 pci-e boards.

i just couldnt get stable voltage if i set vcore>1.6V -.-"

Should I pick up a Pentium M 740 with the stepping..

7418A068 SL7EN
RH80536 1800/2M

I'm hoping to stick this in my laptop and pin mod it without having to increase my voltages. Think I have a good chance?

The fsb pinmod only works with the 7x5 processors. According to that serial number, the processor is a 745. So the pinmod will work, but chances are that you're going to have to increase voltage (which you can also do via pin jumpers btw) to get it stable at 533MHz fsb. Your basically talking about running a B1 at 2.4GHz with 1.308 volts. Chances are it's not going to happen.

BTW this is the wrong thread. PM me if you need some more info.

my dothan don't need volts, check this shizzle!

yeh, some don't..

my celeron M didn't.. but the ones that react to volts are gonna come out best tbh..

How many of you guys use over 1.6v?
12-27-2005, 05:29 PM

and with what cooling? :D

i wouldnt use more than 1.6v for 24/7...at least not with air or wathercooling.

lost another p4c800-dlx.. in normal (def vcore etc) conditions..
comp hanged during bootup, refused to power up after that,
removed cpu, adapter, cards and ram and powered it up.
BANG and this big black cap jumped out.. almost hit me in the face..

Does that bad-boy have CT-479 support ? Looks like an P4GD1 killer :)

Seems to use Ati Northbridge, so I'd say no...

We'll see.

You should do better then that...

I get this with mem @ 197 :D and a little higher oc...

got my 760 under my big typhoon, with a VERY poorly lapped IHS (atleats its down to the copper), with the coldest air i've ever used to bench..

and set myself brand new records, smashed my old PB's :D

Now I'm confused... I got a M 740 and it hits a wall at 2370MHz no matter what voltage or cooling. I'm running it atm in a P4C800E-Dlx with vdroop, vmem, vcore and vagd mods. The max OC does not change if I give it 1.25v or 1.7v the wall is at 2370MHz, this is kinda strange and uncommon, I also got a partly-modded CT-479 adapter and no use... Does someone have an idea where the problem is...?

Ram/chipset limitation? Try using a divider and a higher multi.

Anyone want to get me to 22 secs?

are you using the 11 latency?

if not, that should get you to 22 secs

if you are, get a higher FSB..

I have tested with different multipliers and I know that my board can do 270MHz (did it with my P4) and my new memory can do 255MHz at 2-2-2-5 so those two are unlikely holding me back. It's like a brick wall, no matter what multiplier, voltage or cooling (tried with the adapters heatsink) I throw at it is wount budge.

Looks like a real crappy CPU :/

Try 9x and see how far you go with the rest of your settings the same and 1:1.
