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. -- MiniDisc_2k2 To reply, replace nospam.com with cox dot net. "Mark Grant" wrote in message ...

Have you tried uping the memory voltage to 2.7 to make it more stable. You can't believe a lot of the overclocks that people claim to get with the 2.4,the only purpose the computer serves is to see high the can overclock it. DOUG |

Now I have done some research and realized that its not the CPU that's
holding me back, its the northbridge. It needs better cooling than stock, so I have ordered a Zalman northbridge heatsink...there only $7. Well see what kind of results that i get then. Mark |

Strange, I actually get better performance and fewer crashes with lower
voltage. Right now I am running it at 1.6 v. If I go higher, the system gets buggy. Mark That would mean that you're overvolting it. Yes, if you push the voltage too high your CPU could get "buggy." This means that 1.6v is what you should use for your current speed. |

1.6v? I wish I had a newer P4PE, I Can't set it that low: 1.huh?I forgot
again... But I can't set it at 1.6 but can set it to 1.8v Unless that's just what you get with the P4 2.4B (533Mhz) "MiniDisc_2k2" wrote in message ...

mine runs fine with my asus mobo i run it at 3.150Ghz leave the vcote at
auto or 1.6 make sure your age/pci is a 66/33 maybe it is your memory freq that is too high try turning it down... hope this hepls.. Regards Eric PS: In my opinion asus mobos are the best to o/c with my p4pe rocks... "MiniDisc_2k2" wrote in message ... I've got a Northwood 2.4 as well and I can only get it up to 2.95GHz.

Thanks in advance for any idears, Mark Have you dissabled the last two options on the "game accelerator" tab in the BIOS? A lot of people seem to get 30-40 or so on top of their FSB just by dissabling that option. Also I would not push the voltage up that high. Your seriously killing the life of the CPU at 1.8v. The recommendation I see is to not go over 1.7v but personally I try to stay below 1.6. Eric |
