How high can a 2.0A P4 go?

hello
I got a P4 2.0a Pack date of 8/21/02 (SL5ZT Costa Rica). It does 133 FSB @ 1.675v rock stable (2.66 Ghz). I can do 2.70 Ghz w/ 1.75v rock stable too. it wont do 2.80 Ghz yet. Probably it needs to be burned in for that.
will keep you posted though. Oh yeah, it does 2.4 Ghz @ default voltage.
hope that helps.
THanks

hmmm...dug...what vcore voltage are you using?
No go at 2.8Ghz. Everything runs fine except every once in awhile I get kicked back to the desktop running 3dmark.
Looks good at 2.76Ghz though.
Funny thing is- the temps are the same at 2.0Ghz as they are at 2.8Ghz.
Anybody got any ideas. Ram is fine. Its been tested up to 160fsb stable. Voltages look fine. AGP/PCI is locked at 66/33.

I'm going to leave it at 1.6v at 2.7Ghz for awhile until I can pinpoint what's going on. Possible limitation of the chip. The chip is brand new and I haven't even let the artic silver set on it yet.
I'm water cooled and even at 2.8Ghz under full load I have never gone above 36c. Ambient temp is 29c.
So much for hitting the 150fsb for 3ghz.
+3.3 2.59
+5.00 5.08
+12.00 12.10
-12.00 -12.35
-5.00 -4.99

NEVERMIND EVERYBODY
I got my 2.0A to 2.7ghz stable at 1.65v; i was running at 2.75 at 1.70v, but toned it down to 2.7ghz and then dropped the voltage. Haven't burned it in yet, and i'm still running on the stock hsf =) but overall i'm very very very very pleased.

You hear a lot about guys hitting 3 gig with a 2.26b, or 2.53b, or 2.0a, and I tell ya, these guys are probably not checking their stability with 3DMark2000. For some reason, I find the "B" chips are real sensitive to 3DMark2000 compared to 3DMark2001. Most guys clear 3DMark2001 and call it a day.
On one 2.26b I have, 3DMark2001 runs fine at 175 fsb but I have to drop down to 170 to pass 3DMark2000. Now, I routinely run this first to check for stability on an overclock.
I have a 2.26b at 2.99 gig, a 2.0a at 2.9 gig, and a 2.53b at 2.93 gig, and what's keeping me from hitting 3 gig at reasonable voltage (1.7-1.75 volts) is 3DMark2000 kicking out to the desktop. I can eliminate this at 1.80-1.85 volts, but don't wanna run that high. All cpus boot up happily at 3 gig, no blue screens or random reboots, but that 3DMark2000 is the kicker. As far as I'm concerned, a rig is not stable unless it can clear both 3DMarks. And to be 3D stable, they also have to pass the Second Sam 2nd Encounter and IL-2 Sturmovik demo loop, CodeCreatures, Vulpine GLMark, X-Island, Wolfman demo, and a 40' SuperPI run. Unbelievably, my P4T533 has done this with both an "A" and "B" chip.
On one 2.26b I have, it passed all the tests at 165 fsb, 1.7 volts, except the IL-2 Sturmovik demo would lock up after 10'. Sure enough, I ran SuperPI and it failed. I had to drop down to 162 at 1.8 volts to clear the latter two. But if you didn't run these two tests you'd swear it was stable. How many guys post at DDR460 or something, grab a Sandra memory screen, maybe clear one run of 3DMark2001, and proclaim they are stable?
My 2.0a will do 145 fsb for 2.9 gig, but it needs 1.8 volts. Since this is one of 4 rigs, I run it this way since I don't use it every night. It is perfect for my P4T-E, since my RDRAM maxes out at 145/4x, giving me 3600 bandwidth @ 2.9 gig. This is one sweet rig, clocking one of the best 3DMark2001 scores I've ever gotten. The chip is a 6-17 pack date Phillipines.

Your right Clevor. I can boot and run Sandra benchmarks and 3dmarks at 2.82Ghz. But if I throw Prime into the equation at the same time I'll get an error.
I think running prime and a 3d ap at the same time over and over is good enough to test stability. At least for what I use my computer for, games.
The funny thing is, I find that NeverWinterNights really puts a heavy load on my system. I can run prime and 3dmark at 2.8, but NWN will crash after about 15 minutes.
So I guess I'm stuck at 2.76 for now. I still think this chip has room to go though, because the temp hasn't gone up at all.
