OCing p4 3 GHz Northy

post #1 of 10
Thread Starter 
With the following rig I can only go about ~ 3.40 Ghz w/o windows crashing or something freezing. I have ddr ram on 400. Setting to 266 will let me go as high as 3.51 or even 3.6 but that means a big drop in points in Aq3 and I loose FPS. I run temps 36-38 idle and 55-57 max load. How can I go higher w/o setting the ddr on 266?

Note: My ram is NOT dual channel.

Before overclocking a Prescott I would invest in some better cooling. First though, you need to see what revision your Prescott processor is as the D(0) revision is not at all a good overclock processor and will need better cooling even at stock. What is your max load at stock?

Your power supply is not adequate for a stock Prescott and your setup. Move to a better PSU such as a 450Watt Fortron, Enermax, Antec etc.

Download CPU-z and post a screenshot.

No, D1 is fine. You still need a better power supply for overclocking. A 400Watt or higher for the Northwood and one that is a name brand such as I mentioned. I also would get a decent aftermarket cooler for the overclock.

Here's a bit of a guide.
Main:
  • IDE Configuration (Disregard these settings if you have RAID running)
  • Onboard IDE Operate Mode: Enhanced Mode
  • Enhanced Mode Support On: S-ATA
  • Configure S-ATA as RAID: No
  • IDE Detect Time Out: 0
  • Primary HD (If you don't run a RAID)
  • Everything is at Auto except..
  • SMART Monitoring: Disabled
  • 32Bit Transfer: Disabled

Advanced:

  • JumperFree Configuration
  • AI Overclock Tuner: Manual
  • CPU External Frequency (Mhz): 250 (This is where you will raise the fsb)
  • DRAM Frequency: 266 (Forces pc2100 and will exclude the dram from the overclock, you will get to this after you find your successful overclock)
  • AGP/PCI Frequency: 66.6/33.3
  • CPU Vcore Voltage: 1.55 ( Try 1.5V and raise if necessary. Prime95 will show if you need to raise the Vcore.
  • DDR Reference Voltage: Auto (Leave at "Auto" for now. When you have your overclock you can then use this to help

    tweak your DRAM
  • AGP VDDQ Voltage: 1.50V (This is default. I suggest you leave this at default)
  • Performance Mode: Auto (After you have defined your CPU and Dram speed, you can test this by setting it to "Turbo")

CPU Configuration:
  • CPUID Maximum Value Limit: Disabled (Default)
  • Hyper Threading Technology: Enabled (For your HT Prescott)

Chipset:
  • Configure DRAM Timing by SPD: Enabled
  • Memory Acceleration Mode: Enabled (MAM=PAT)
  • DRAM Idle Times: 16T
  • DRAM Refresh Rate: 15.6uSec
  • Graphics Adapter Priority: AGP/PCI
  • Graphics Adapter Size: 128 (For Your 9250 if it is 128MB, Set to 64MB if you have 256MB)
  • Spread Spectrum: Disabled (Make certain you disable this)
  • MPS Revision: 1.4

Onboard Devices Configuration: (All my serial, parallel ports are disabled as I do not make use of them)
  • Onboard AC'97 Audio: Auto (Disable if you use a PCI sound card)
  • Onboard LAN: Enabled (Disable if you use a PCI NIC)
  • Onboard LAN Boot ROM: Disabled
  • Onboard Floppy Controller: Enabled (Disable if you do not use a floppy)

PCIPnP:
  • Plug And Play O/S: No (Only set this to Yes when Installing your OS)
  • PCI Latency Timer: Leave at Default
  • Allocate IRQ to PCI VGA: Yes (This is important)
  • Palette Snooping: Disabled
  • PCI IDE BusMaster: Enabled

USB Configuration:
  • USB Function: (Set this to how many USB ports you actually use)
  • Legacy USB Support: Disabled (Unless you use a USB Keyboard/Mouse)
  • USB 2.0 Controller: Enabled
  • Instant Music Configuration: Disabled

Power:
  • Suspend Mode: Auto
  • Repost Video on S3 Resume: No (Unless your Video is garbled when coming out of standby)
  • ACPI 2.0 Support: No
  • ACPI APIC Support: Enabled
  • Bios->AML ACPI Table: Enabled

APM Configuration:
  • Power Management/APM: Disabled
  • Power Button Mode: On/Off
  • Restore on AC PowerLoss: Power Off
  • Everything else under here is disabled by default
  • Hardware Monitor (Take note of your temps and voltages)
  • Q-Fan Control: Disabled (If you use a Cooling Device that does not make use of this feature, Enabled if you use the stock fan/heatsink assembly)

Boot:
  • Boot Settings Configuration
  • Quick Boot: Enabled
  • Full Screen Logo: Disabled
  • Add On ROM Display Mode: Force BIOS
  • Bootup Num-Lock: On
  • PS/2 Mouse Support: Disabled (Enable if you use a PS2 mouse)
  • Typmatic Rate: Fast
  • Boot to OS/2: No
  • Wait For "F1" If Error: Enabled
  • Hit "DEL" Message Display: Enabled

Yeah I basically have those exact settings that you said. Im not sure if the temps are good? 36-38 idle and 55-57 load? Yeah I think I need a better psu but it wouldn;t do miracles will it? also is there an advantage running ddr ar 266 and cpu at 3.6 instead of my current 400 and 3.39? Because when I benchmark, I seem to loose points and fps.

Your load temps are very high for that processor and that speed. You can not use stock cooling/thermal pad that comes with it and expect a decent thermal envelope.

You are throttling your processor and losing points. Get a decent psu and cooling. You do not want to run your ddr at 266. You want to run it at 1:1 if you want decent marks.

You are not running dual channel. Your dram is down to 266 and raised with your fsb so it is not at 266.

If you want an overclocked rig then you need the parts that will allow a decent one.

As it is, I say stick with 3.39 and 400MHz single channel. Anymore will not help your current setup.

How do I run 1:1? Theres an option 266, 320 , 400 , 500 , and 533 and AUTO. When I go to auto, It automatically goes down to 266 as displayed in Everest.

What make is the ram? Is it PC3200 Value ram? If so then you can't make 1:1 with it and will have to keep it down. To gain decent overclocks one needs decent overclocking parts.

It's like racing cars. One can not buy a car from stock and expect it to race like a racing car. One needs to buy the parts necessary. To get one to one you need ram that will take the overclock of the CPU. If your CPU is at 250MHz then you need ram at DDR500 and in dual channel this makes 1000MHz since your 250MHz CPU is quad pumped bringing it to 1000MHz as well. However, without the cooling you will still throttle the processor and lose points. It all works together. Now the good thing is that you have (by the looks of it) a good processor for overclocking and an excellent motherboard as well. Your video card is no slouch and can be pumped up as well. So, a good CPU cooler and powersupply will allow you to do a better overclock. The cooler is necessary, not a luxury.

Yeah true. I think its some crap brand. The 512 stick is simpletech and the other 2 256 sticks are something else.

Thx for da help =) I'll stick to my current cpu speed.

If you have 1 X 512 and 2 X 256 you may be able to make Dual Channel.

Put 1 X 256 in Dimm 1 and 1 X 256 in Dimm 3. Put the 1 X 512 in Dimm 4. Check and see if you have dual channel. If the timings are the same then you may make Dual Channel mode.
