Problems with 3.0C!

3.0C
SL6WU
12 Cap
Pack Date: March 31/2004

Running at 244FSB for 3.66Ghz 1:1. Memory timings are totally relaxed until I find max of CPU but with 244FSB stable I ran 3DMARK03 and got 6720 which is the same as my old 2.4C at 275FSB. So now I just need to figure out how to get alittle more out of it for my 3.75Ghz goal and to get these temps down, arg.

Its already slightly faster then the 2.4C was at 275FSB (3.3Ghz).

3DMARK03 = 6720
3DMARK01 = 20843
AM3 = 20843

So pretty much the same right now as the 2.4C was maxed. If I can get this baby alittle higher, it should yield some nice results. These scores were with the ram at 3-4-4-7 until I find the CPU max. Then the ram will tighten up to 2.5-3-3-7. I'll post CPU Arithmetic and multimedia to compare. Is your 3.0C stuck at 244FSB max?

Seems max stable is gonna be around 3.6Ghz at 1.6V-1.65V! which gives 64C LOAD! :( I think I may sell this one and try my luck with another, but before I do I have an extra IC7 here, so I'll try this chip in that board to make sure its not this new IC7 (RMA)

I was really hoping for 3.75, but 3.6 at 64C is crazy. Its still an overclock I know, but at 1.7V this thing will boot into windows at 3.9Ghz.

EDIT: Forgot to add, the NB fan/heatsink is HOT, like fry some eggs and bacon HOT! At 1.6V it was too hot to really touch. This is the round aluminum one on the IC7. The old one is the low plastic one, so maybe that will help. So far 3.6Ghz at 1.6-1.65V seems pretty stable, so i'll try upping it to like 244FSB again from current 240FSB.

If your metal heatsink is too hot then i doubt a "plastic" one will yeild better results...

My chip tops out @ 240~244 with default VCore (1.424) but need about 1.55 to get to 250. Alot of volts for low yeild :/

Switched back to the older model IC7 and it helped temps alot! so I think the temp gauge is wacky on the newer IC7 I had. Temps are now 38c idle and 56c load at 1.675V. This chip won't do 250FSB stable at all. Even at 1.675V, so i'm trying 244FSB since thats where alot of people get stuck at. Tried sandra burn-in overnight and it locked up at somepoint at 244FSB, screen stayed black until I switched MB, tried clearing CMOS, pulled the battery for a second, still black screen...weird.
 
Anything over 244 fsb on my 3.0C and windows will crash almost instantly.
How did you score so much higher than me in sisoft sandra when we're running almost the same speed?
 
This chip will boot into windows at 260FSB (3.9) but is no where near stable there, even at high vcore. at 250FSB right now at 1.75 Vcore it just failed 1 prime after 11minutes, the second one is still going. So 250 is definately not gonna happen, even at 1.75V! guess its 244 test time again

as for the score, i have no idea why its higher...different systems do different things i guess.
 
I just ran the tests again with everything off. The first time, I had my firewall and mIRC running. Looks normal now.

I've had to bump up the vcore on this P4 to 1.55 because of instability issues.
Why do I never get the P4 that wants to do 4 ghz effortlessly on air? This is my fourth damn P4 and none of them have been as good as I would like them to be.
 
i've got 3.0c 30 cap on a p4p800 that goes 100% stable at 245 fsb with junk ram. And my temps are 27 idle and about 42 load on air. when i get some good ram im confident i can push this thing to around 260 fsb 1:1 stable. :)
 
Thats insane. This chip won't do 250 stable even at a P4 cooking 1.75V. Seems to be running fine at 3.66 (244) at 1.65V. If it passes prime then i'll try again with lower volts. 3.66 is nothing bad, but the temps are still alittle higher then i'd like. Maybe when the AS5 settles, they will go down a few degree's. I was really hoping for 250 1:1 but there is no way, it just won't do it, oh well. 3.66Ghz will still play all the games I want to play with the 9800 Pro overclocked to 450/380.
 
It failed prime 53 minutes in at 240FSB at 1.65V, screw it...its going on ebay. I just need to decide if its better to get a AMD64 3000+ or try another 3.0C. This system is for games and internet. If it won't go stable at 3.6 at 1.65V then its gotta go.
 
True, but its either get another 3.0C or grab an AMD 64 3000+ for $298cdn. As for motherboard I can just sell it on ebay as a package and grab an AMD board. 3.55 is likely all i'm gonna get stable, even at 1.65V! Now its just deciding which CPU to get. All I do is net and games on this system, nothing like video editing, so either CPU will do what I need easily, but i'm thinking of trying the new AMD's...3.55 is pretty disappointing as my old 2.4C did 3.3Ghz with much lower temps and gets the same scores as this system did at 3.66 (both 3dmark, am3)
 
See if you can get a SL6WK 3.0c...looks like most people can hit 3.7ghz with that stepping on 1.55v... i think you chip is what is holding you back and not your MB...
 
3.0C and IC7 are going (listed in forums), i'm definately gonna try the AMD64 3200+ with an MSI K8N Neo Motherboard :D
