Cant get 2.4C to 3ghz....any ideas..?

Hello,

Based on advice from this group,
I just built a system using the following:

My goal was to run it at 3.0ghz (12X250). It will boot, it will post, it
will do most applications okay, but when I run Medal of Honor or MS
Flightsim 2000, it crashes. I either get the blue screen (lower voltages on
cpu) or a windows "weve encountered a problem and have to close ___" (higher
voltages on cpu.

I am frustrated because I thought most all 2.4C with good memory would run
at 12X250. Does anyone have any suggestions ? The highest voltage that I
have tried so far on the CPU is 1.8. I am afraid to run it any higher
although my BIOS supports up to 1.9.

Heat isnt really a factor. The hottest I have got it to so far is 45C. I am
kind of disappointed because I upgraded from a 2800+ Barton, and this system
is slower at the factory default setting. It is only about 8% faster running
at 3.0ghz.

Here's my stuff:


PIV 2.4C
Abit IS7 bios upgrade to 13
Zalman 7000C heatsnk / fan
Antec Case w/ 400 watt PS
Corsair 3200 LL 512MB Ram (1 stick)
Ati 9500 Pro latest drivers
XP Service pack 1

By the way, the Zalman cooler rocks.

Thanks in advance for any idears,

Mark

I've got a Northwood 2.4 as well and I can only get it up to 2.95GHz. Grant
it that you're using a 12x multiplier and I'm using an 18x, so there will be
differences (yours will be a bit easier to OC) but it seems you've maxxed
out. The CPU does still use the 13 micron, 1.5V technology, so there are
some similarities. Mine won't post above a 164FSB (164*18 = 2952, what it's
running at right now). You're getting a little luckier. It'll post but won't
be stable. I'd just recommend increasing the voltage a bit. If you can't get
it then, I don't think you'll be able to go that high. Remember all CPUs are
different and while some people may get up to 3.2GHz, some won't get more
than a 400MHz boost. My VCore's at 1.675V and it's safe with a stock cooler.
I wouldn't recommend going higher than that. If you hit 1.675V and can't get
it stable, I'd give up.
