Need help on Asus P4P800E-Deluxe + 2.4 GHz Prescott

post #1 of 36
Thread Starter 
Hello good overclock guru,
I can use some supports and ideas, let's start out with my specification:
- Intel Prescott 2.4GHz
- Asus P4P800E-Deluxe with firmware 1009 (2005)
- Kingston 1GBytes 3200 single module
- ARCTIC COOLING Freezer 4 ACFZ4 80mm Ceramic CPU Cooling
- ATI 9600 Pro. with 128MB on-board
- Antec True Quiet Power Supply 350W
O.K, here is how it goes, I can ONLY overclock this baby only upto 2.880Ghz with 160FSB x 18, at Vcore of 1.36V, the temp is 42C when running Prime95 for at least 6 hours straigth. If I goes beyond the 160FSB - then Windows would boot-up but the Prime95 will not complete it runs. The Prime95 response back with unstable CPU. I've already tried to increase the VCore upto 1.45V with 161FSB and it's still not working. Have I missing anything? By the way, I keep the ratio 1:1 on the DDR-RAM and CPU. I have read before that with this CPU (Prescott 2.4Ghz), some one can take it upto 3.11GHz - no problem and very stable. Can some one explain to me what is the "divider" when talking about the memory timing. Thanks so much for your help.

Since your Prescott is a 533MHz fsb processor you will not need a divider with PC3200 DDR RAM. That is because your ram is spec'd for a faster 800MHz fsb and your overclock will not go that high.

Have you locked your AGP/PCI?

Please enter your system specifications by the link at the top of the page specified by (User CP).

Thanks Ropey, but the specification is exactly as I've indicated. And my AGP/PCI is set to AUTO. When I increased the VCore, the system will boot into Windows XP but the PRIME95 will not run completed testing. It look to me like this setup will only goes as high as 2.880GHz and no more.... The CPU I have is an Prescott 2.4A with label of SL7E8.
Anyhow, just what the heck is the memory divider? Please explain.

You need to set your AGP/PCI to 66.66/33.33 or you are concurrently raising the fragile ancillary PCI and AGP busses. Doing so can damage your system.

Please specify your entire system as requested and I will give advice that WILL help you to overclock your system correctly.

If you can't do that then I can't help. Let's work together. Lest I appear too brunt, let me give you one scenerio. We are working to get your system stable and a high overclock. We are into two or three pages. I have to either write down your specs or go back continually to check what you have as it might take days and to keep your entire system in memory while helping you and others is a task indeed.

This is only one reason for the requirement.

Dopley,
It's done. It's not that I do not wanted to display my specification of the system BUT I JUST DON'T HOW YET (because I'm still new to the forum). I'm recently discovered the process and fill in the info. like you've asked. Anyhow, can you explain to me what is the memory divider is? And why is it I must change the AGP/PCI to 66.66/33.33 or damage will occurred? Should I change it ASAP? As you can see, I tried to keep everything 1:1 ratio - would it be better...

A memory divider does exactly that. It divides the ratio of 1:1 (CPU:RAM) so that lower value dram can work with higher CPU overclocks. Since you have a 533MHz FSB CPU and 800MHz DRAM you need not use the Divider but it is always a good thing to set it at the lowest (266MHz) when overclocking to isolate dram issues from the overclock equation.

You need to lock your AGP/PCI so that these busses do not concurrently raise with the FSB overclock raise.

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:Enabled

Advanced:

  • JumperFree Configuration
  • AI Overclock Tuner: Manual
  • CPU External Frequency (Mhz): 133 (This is where you will raise the fsb) Set to 160 and test for stability. If stable raise incrementally and retest.
  • 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: 1.35 (This is where you will raise your vcore. 1.35V is a good place to start when beginning to overclock a Prescott.
  • 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

CPU Configuration:
  • CPUID Maximum Value Limit: Disabled (Default)
  • Hyper Threading Technology: Disabled (For your Non-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 9600 Pro 128)
  • 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
  • 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, install the Asus Probe utility found on the Asus driver disk)
  • Q-Fan Control: Disabled (You are using an ARCTIC COOLING Freezer 4 that does not make use of this feature)

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 (Who uses this anyways?)
  • Wait For "F1" If Error: Enabled
  • Hit "DEL" Message Display: Enabled

Awsome Ropey and Thank You so much. I'll give it a try tonight again...
Anyhow, I'm trying with it all night by increase the FSB from 160 to 161, and play around with the VCore from 1.36v(AUTO) increment as in the BIOS has already config. TO 1.5v. The result is still the same. The system will boot into Windows XP just fine, but I tried to run both OCCT and PRIME95 test, either one can be finished. Both of the programs reported as "unstable CPU"; although the system still perform just fine. Just to stay on the safe site, I download the VCore to 1.36v and set back to 160FSB. And the testings went through O.K. Do you think I might have hit the ceiling with this mobo + CPU? Anyhow, I'll let you know the process further tomorrow - Thanks

Are you sure you have not set the AGP/PCI to 66.66/33.33? I can't believe that you are not even able to hit 3.0GHz on that system.

"YES", I have set the AGP/PCI to 66.66/33.33 - just like you recommended it and I just cannot exceed my max limit: 2.880GHZ (160FSB). I leave the FSB to 161 and just increment the VCore from 1.36v(AUTO setting) to 1.5v. And it would boot into Windows just fine - but never completed/passed both the OCCT and PRIME95 testing. So, I'm just would DARE try further. Again, I'll try out your setting in the system tonight and report the result to you tomorror ASAP.
One thing I did notice that the ASUS mobo label as P4P800E-DELUXE, but the CPU-Z v1.32 reported as P4P800E (only) not DELUXE???? Is that normal? The current bios in this mobo is ver 1009 (September 2005), but base on ASUS Web site, the latest BIOS version is 1008 (26Sept2005)? I'm abit confusing. ddedicate

You might be at the limit for that processor. Sometimes you can get ones that are pretty poor overclockers and if you can't make 161FSB with 1.5V then I would say that this is the problem. CPU-Z would report the deluxe as a P4P800-E.

You can update the BIOS to see if that will help but my money is on the processor being a poor overclocker. I've taken 2.4A's on a P4P800-SE board to 3.4GHz with ~1.45V.
