Just curious. I'm overclocking my Abit AI7 and Buffalo Tech PC3700 to 210MHz
FSB 1:1 at 2.8V DIMM. I can probably get more out of it if I up the memory
voltage, but wasn't sure how far people have gone in this area. So what all
are you running at?

If you are running PC3700 @ 210MHz, you are actually underclocking this
memory as it is rated to run at 1:1 on a 233MHz FSB. I wouldn't think
increasing voltage on the memory is necessary at this point.

As for your question,

Kingston HyperX PC3500 1GB Dual Channel (CH-5 chips) @ stock 2.6v
ASUS P4C800-E Deluxe with Thermaltake Crystal Orb on Northbridge
Intel P4C 2.8GHz cooled by Zalman CNPS7000A copper HS and 92mm fan

I have pushed the FSB to 235 with relaxed timings, but system is only stable
with RAM at 1:1 at 230MHz. Since I was more than happy with 3.22GHz system
speed, I haven't bothered tinkering with voltages and such.<!-- ~MESSAGE_AFTER~ -->

Yes, I know, but frankly I have been unable to get this up to 233MHz at up
to 2.8 VDIMM. These sticks were tested at Buffalo Tech at 240MHz, but for
some reason in my AI7 I can't get them anywhere near that speed.<!-- ~MESSAGE_AFTER~ -->

Either the memory is not the limiting factor in your system, or it is bad.

P4 2.6C, currently running at (210x13) 2730MHz. CPU voltage is currently
1.55. Zalman CuAl7000 on the CPU. I am running with case open right now, so
my temps are CPU - 21C, SYS - 18C, PWM - 24C. I do not believe the memory is
bad, as I have run Prime95 and memtest86 at both 200 and 210 MHz for tens of
hours with no problem at all. The interesting this is that if I use only one
stick instead of two (doesn't matter which one), I can push the FSB up
higher than with both. Using the latest BIOS for this Abit board. The tech
at Buffalo Tech indicated that there were no memtest errors with this stuff
at 240MHz, but he was using a DFI board, I believe. I'm starting to wonder
if this rev 1.0 AI7 board is not yet suited to support oc'ing. I know that
in the past other Abit boards have improved on this capability after the
first rev.<!-- ~MESSAGE_AFTER~ -->

Is your Buffalo Tech using Micron on Winbond chips? My BT PC3700 uses
Winbond BH-5. I can get 230+ 1:1 with loose timings, but the cpu and overall
system performance are higher at 5:4 with lower memory speeds and tighter
timings. (I've heard the Micron can run at slightly higher speeds, but
chokes on tighter timings.)

I'm running an Abit IC7. My P4C 2.4 runs at 275x12=3.3ghz at 1.575v. The
memory is set at 5:4, 220 mhz, 2,3,2,6. It works best at 2.8v, as high as I
can run the voltage on my IC7. I've heard reports from others that the BH-5
thrives on voltage and runs well at 2.9 or 3. Can't say about the Micron,
it's fairly new and I haven't seen a review or more than a handful of owner
comments.

Voltage is important, but bios settings are even more so. GAT is the worst
offender on Abit boards. The only settings that don't cause problems for me
are all-Auto or Auto,Auto,Auto, Disabled, Disabled. And I can't run reliably
with the NB Strap at anything other than 800.

My suggestion is to try 5:4. Even if you get the memory stable at 240 your
2.6 will be at 3.12 ghz, and it's likely capable of more. At 5:4 with an fsb
of 250, you'll be at 3.25 and the memory will be idling at 200. At the 210
you're getting now, the fsb would be at 2.60+ and the cpu would be at 3.4+.<!-- ~MESSAGE_AFTER~ -->

You may recall I wound up getting the Micron chipped modules from BT
directly (Newegg sent me one Micron and one Winbond). The stuff that was
sent to me was tested on a DFI board at 240MHz 1:1 at BT.

I've been wondering what is the highest VDIMM that can be used before
risking damage to a module. There must be some specification somewhere that
the chip manufacturers must meet, at a minimum.

I'm running Auto,Auto,Auto, Disabled, Disabled, although I haven't tried
fixing the NB strap yet.

Hi Skid and all:

I've been lurking for a while, attempting to learn something about
overclocking before jumping in and screwing up my new system. Smile

I'm building a P4 2.6C, Abit IC7, Kingston HyperX KHX3200K2/1G 1GB Kit
DDR400 PC3200 Memory, don't know if everyone realizes the difference between
KHX3200K2 and KHX3200AK2. The KHX3200K2's timing is at 2-2-2-6-1 so I assume
that it is very overclockable.

I have the requisite PSU, CPU cooler, quality case with extra fans etc.

So I am ready to begin overclocking right after I install XP, chipset
drivers, etc.

I am going to use the system for gaming, mostly Flight Simulator FS2004, I
would like to overclock to 3.0 - 3.2 GHz or even higher if I can maintain
system stability and not run into problems caused by excessive heating.

Never having overclocked before I have been studying websites and newsgroups
and I think I understand the process somewhat.

What is the very first step I should take in the BIOS? Assuming everything
else is installed correctly and ready to go.

A small primer on steps 1,2,3,4,5,6... would be greatly appreciated. :->

Thanks and Happy New Year to all,

Dashi, there is a very good thread you can read here

<a style='text-decoration: underline;' href="http://www.systemcooling.com/modules.php?name=News&file=article&sid=417" target="_blank">http://www.systemcooling.com/modules.php?name=News&file=article&sid=417</a>

that goes over the fundamental issues of oc'ing very well. He used an Epox
board, but the concept carries to any decent motherboard. Note the comments
about not skimping on things like power and cooling for an oc'd system.
Probably the first thing you should do after putting your system together is
let it run at stock voltages (CPU, DIMM, AGP) and speeds (FSB, DIMM timings)
for a while, until you feel comfortable with how it operates under various
conditions. Next, burn the system in using Prime95 and / or Sandra. These
will also give you a good indication if there are any operating problems in
a stock configuration. There shouldn't be. You should also consider running
memtest86 at some length (several hours at least). It is pretty much the
accepted standard for memory testing in a clean-boot environment. It sounds
like this will take a little time (and it will), but it will help you when
you start overclocking.

I won't get into where it's best to start, other than to say that it pays
not to rush. If you're working on FSB speed, don't up it by more than about
5MHz at a time, carefully noting the stability and temps while running
stress scenarios. If you reach a point where some instability is noted, you
may want to crank up the voltage of either the CPU or DIMMS (depending on
which one makes sense) only one step, maybe two at the most. Then check it
again. It's an iterative process. Always keep an eye on stability, voltages,
and temps. With an IC7 you should be able to use Motherboard Monitor 5 in
XP. Use it. Bottom line is to know when to stop. With an air-cooled system
and good components you should be able to get a 2.6C up to 3GHz or so, but
be careful about CPU voltage (and ultimately NB temps). There's quite a lot
of information about Sudden Northbridge Death Syndrome (SNDS) that seems to
be related to CPU voltages at 1.7VDC and above. Lastly, my opinion is that
any error - any - in memtest86, Prime95, or Sandra is an indication that you
will ultimately have trouble. If it can be overcome with judicious raising
of voltage, then fine. But some people will get there systems cranked up so
they can just get an ultimate benchmark, brag about it, and not be able to
use it that way. Try not to be too caught up in that.<!-- ~MESSAGE_AFTER~ -->

In addition to Tony's sage advice, there are good overclocking guides and

With PC3200 and a P4C 2.6, you should experiment with the 5:4 cpu:ram ratio.
With your cpu running at 250 fsb or 3.25 ghz, your memory would be at spec
running 200 mhz CAS 2.

Like Tony says, start at stock and work your way up, but that's a reasonable
goal.<!-- ~MESSAGE_AFTER~ -->

Thanks Skid, excellent advice, I'll check out all of the links.
