How to volt mod my P4C800-Deluxe

Sir ScissorClaw

Okay here's my situation. I have a P4C800 Deluxe with a 3.0C running
at 3.255 at the moment. It has a swifty MCX4000 HS and a 92mm
thermaltake fan hooked up. Here's the kicker, for christmas with my
work bonus, I am buying myself a Chip-Con (now nVentiv) Promethia Mach
II. WAHOOOO!!!! I already have a 512MB Dual PC4200 EL kit for the
memory. I am definetly going to need to volt mod the mobo to reach the
speeds I want to, both with the 3.0C, and the 2.4C I recently aquired
(needless to say, I am going to be havin an awful lot of fun xmas
night).
Now, I have NEVER attempted a volt mod before and have scoured the net
for a way to do it, but the best I could come up with was somewhat
vague descriptions, or directions for folks who are "in the know"
about these things.
Can anybody tell me how to do this correctly, or lead me to a
trustworthy site that could help? Any help would be much appreciated
and I will definetly keep you all updated on the progress with
pictures and stories from good ole' New Jersey!

Have fun damaging your board in the pursuit of a few more MHz, sucker.

Take a look here. Select the Pentium 3.0C entry.

http://www.cpudatabase.com/CPUdb

What you'll notice is that several people use 1.7 volts for Vcore, but
only the guys with refrigerator systems get the high overclock. So,
a good cooling system is all you need - no further abuse is required :-)

When you do the install, be very careful to seal the processor from
outside air, as condensation of moisture from the air, onto metal
conductors in the processor area, is what kills these systems.
Corrosion can happen in a matter of months.

HTH,
Paul

Unfortunately that database only shows the volts that the CPU was
pushed too. It doesn't show the memory volts. I've also been told that
the installation kit that comes with the chip-con promethia mach II
has an almost fool-proof install system. The memory I have is
certified up to 3.0 and the P4C800 doesn't go that high. Adding that
extra voltage definrtly gives the memory moduloes more headroom. I
found a really good thread after I posted this thread at
http://www.xtremesystems.org/forums/showthread.php?s=&threadid=13402.
Theres alot to go on their. Thanks though Paul. At least you don't
have your head up your ass like the other guy.
 
repetition is the ingredient that keeps me up to date.

I would like to upgrade to p4c800-e deluxe and 512(2x256) EL4200. I think
this test is for 1024, don't know what diff it makes.
I'll get prob a 2.6C or 2.8C box CPU.

From these tests, benchmarks show the that the highest performance, by far,
by my reckoning, comes from the highest memory overclocking, regardless of
the CAS (a-b-c-d-e) ratings. This board and RAM seems to go together (see
first sentence)

I don't know what you need to know, or even what I'm telling you, but I have
some questions:

3-3-4-7 @2.85V @560 @1:1. Don't know what this means. Just looks
good(better). May even be better numbers elsewhere.
I assume once I've done this on the MB I have covered the max. RAM
performance task. because I guess @560, not being @400 means FSB1120, not
FSB800

Q1: What about overclocking the CPU to max this performance parameter?

Q2: Will using an ATI 64MB DDR Radeon VIVO AGP4x restrict the ability to
use all of these maximized performance setttings? i.e fsb, and cpu
overclocking

Q3: Same question, about my other components:
SBLive5.1 PCI
USRV.90 PCI voice 2976
Pioneer 16X DVD116
IBM Deskstar 30GB 7200RPM ( as storage only, as I want to get a 10krpm, 5
ms seek, 37GB WD Raptor SATA HD as o/s boot disk.
 
ok, your orig Q was about volt mods. Is this about my question, overclocking
the cpu, which is not the same as maximizing the RAM performance?

I want to maximize both, but I want to do it with the best components, not
by brute force.. I have seen it is common to overclock a cpu to 30% over
rated MHz. If I found a similar source of information for this procedure
will I likely need extra cooling, beyond the intel cert'd heatsink, and fan?

I think I have a decent 350W ps. Not sure whether or not it, or I can
handle the temp sensor, fan speed, noise questions possible.

pleas e-mail me if you have info in these regards. I'll TRY to keep up w/
newsgroup too.
 
I just spent hours researching and believe this 2.85V is to cover the
advanced FSB drain.
I believe now no other cpu overclocking is possible, as the cpu is locked.
so mobo and ram choices are your only overclocking concerns
don't know yet what to expect about other eg AGP4x, or 512MB RAM, or 2.6C or
2.8C vs their 2.4
