p4 2.4 says its operating at 1200

[redfella]

Thanks for the clarification. I was unaware that there where different multipliers...

Anyways, would it be unwise to run my mobo at 160? The specs say that it should run at 400/533... Will I run into heat issues \ hardware damage if I run it at 160?

I don't think it would be unwise to run it at 160, becuase the CPU is rated for at least 200. It'll be producing more heat than it will be at 100 or 133, becuause it's clocked higher. However, that heat won't be unsafe for your CPU, because it's still running lower than it's rated speed.

Does your motherboard come with software temperature monitoring? The program is usually on the driver disc under "Applications" or "Misc." If it has one, I would suggest installing it after you have set your FSB to 160. Also download Prime95 (http://www.mersenne.org/freesoft.htm). It's a program used to stress test your CPU and RAM. After it's installed, run the temperature monitor program, open Prime95, and go to options than torture test. Use the "In-Place Large FFT's" test. While that test it running, make sure your temp monitor is running, and watch the temperature. As long as it is below 50c, you should be safe.

Run the test for about 15min then just stop it, and if they're was no error, I'd say your safe to run the CPU at 160FSB. Since your not even overclocking your CPU (it's actually underclocked),
you really don't have to do the Prime95 test, as that's mainly used for people who are overclocking their CPU and want to stress test it to make sure it's stable.

You can just set the FSB to 160. Then install your temperature monitor, play some games, or run 3dmark and watch the temps. As long as it's under 50C and programs aren't crashing, it's safe. I doubt it'll go over 50c, since your CPU is underclocked.

You should check if your mobo has pci/agp lock...

If you didn't know that modern cpu's had multipliers to obtain final Mhz speed, you should spend some time first reading material on the internet to understande the ins and out's of modern hardware.
Than, you will be ready to "play" with you hardware without problems...

Getting to your problem, I would suggest one of two things :

- Sell cpu and get a 533 version
- Sell mobo and get one that suport 800fsb

Obviously the cheapest route is going to be getting a board that supports 800 fsb chips. Even a new one would only run about $70 and a used one can be had for under $50 if you shop around the forums.

Right, I understand that I'm not overclocking my CPU... but am I overclocking my FSB? The FSB was only rated at 400/533 for the mobo I have. Is it safe to run it higher than speeds they put in the specs? That's the part I'm questioning.

Thanks again.

Oh ok, I didn't realize that's what you meant. Now that I reread it, I get what you mean.

I can't say if it's safe or not for the motherboard to run at 160FSB. Since that is the highest, it may stress the motherboard. As stormgiant stated, you may need to check if your mobo has PCI/AGP lock, since running at a higer FSB for the CPU might run the PCI or AGP bus too high. Since i'm not exactly sure if it'll be safe for the motherboard, I'll have to let someone else answer your question on whether it'll be ok to set the FSB to the max.

The best option though would be to sell the motherboard and buy one that can run 800FSB CPUs. You could probaly sell your motherboard for around $30-40, and could buy a used board that supports 800FSB for around $50-60 on the FS\FT forums . So you'd only be spending around $20. You could also trying post a "For trade" thread stating that you want to trade the motherboard plus cash for one that supports 800FSB.

AGP/PCI Asynchronous Mode with FSB (fixed AGP/PCI frequencies)

This is what Asus "claims" on the product page for the P4S8X-X, however on my similar P4S800 motherboard which Asus also "claims" the fixed AGP/PCI frequency... nope. I couldn't find any setting in my BIOS, plus seemed to have instabilities running in-between speeds. Unless that's all just my imagination. Possible...

Ok, I just looked at my BIOS again... CPU External Frequency is setup really WIERD. It doesn't give me the option to select 100, 133, 166, 200, etc. Instead, it has 100-160mhz... Ya know, 100, 101, 102, 103, 104, 105, 106, 107, etc. etc.

Retarded. Whomever design this BIOS where morons.

I guess I should try 160? That's the highest setting available.

(and yes, its 800fsb... or so they proclaim on all of their sh!t advertising.)

A classic case of Newbie flaming "morons who designs BIOS"
