Question about Intel (RK80532PG0881M) Pentium 4, 3 GHz Processor

1 Answer

Overheating? Processor running at half speed?

I have an older socket 478 Asus motherboard and I've maxed the machine out with 2gb ram, sort of okay 128mb graphics card and now I've upgraded the processor to an Intel Pentium 4 3.4 ghz processor.


It was quite tough to get hold of a socket 478 processor - but I did find a reseller to said he had some.


They turned out to be unwanted processors from another batch of machines - so they were removed (or so the reseller said). So essentially I bought a used processor - but who cares, so long as it works eh?


I installed the processor myself, but almost immediately began experiencing overheating issues. Thought maybe I applied too much thermal paste.


So I thoroughly cleaned the top of the processor and the heat sink, applied about a pea-sized plop of paste in the middle of the processor and put it all back together. I assume you don't need to spread it all around and that the force of the contact tends to spread the paste evenly.


It still seems to be running too hot - Asus probe is moaning at me for running the processor anywhere from 60 to 67 degrees celsius.


So I downloaded the Intel Processor Identification utility to see what kind of processor it really and matched it to about five different possiblities. These processors seemed to max out at at up to 69 and higher to the low 70 degrees. If that is what they mean in the processor specs page that refers to the processor temerature.


So I thought that maybe these processors just run a bit hot . . . until I noticed that my processor, according to Intel's utility, is only running at 1.77ghz and 416 fsb (should be 800).


I've got quite a large thermal unit on the top of the processor and one additional fan on the front of the case which extracts air directly from the area around the processor fan.


Is the processor overheating? Could it just be a bad processor? Is the processor being sandbagged so as to avoid burning out?

    Thanks for responding so quickly ardmax. Using  your information, some online searching and some new thermal hardware - I solved the problem.


    You were right - the processor is operating as it was designed. Which is that it runs way too hot!


    For anyone else who reads this looking for solutions relating to an Intel Prescott processor running too hot - well there are actually a lot of posts detailing just how hot they run if you search Google.


    I ran a quick home test by getting a desk fan to run over my open box to see if it decreased the processor heat - which did absolutely nothing.


    I guessed that what that meant was that the standard processor fan which shipped with my Asus motherboard was not designed for a mad Intel processor running 10 ? 20 degrees hotter than it should.


    I'm sure other manufacturers also have good third-party processor fans ? but by replacing my standard processor fan with a Thermaltake "Beetle" system I've managed to reduce the processor temp down to about 45 degrees C in idle. It's probably going to heat up with some PS photo editing ? but then I also now have a go faster throttle on the fan ;)


    It was quite difficult to install (don't think something designed for at least four different socket types is going to just click in all by itself). I even had to bend one of the plastic bits at the top with a pair of pliers to get it to fit in my case. I was fully expecting this plastic part to shatter when doing this but it did not. Seems Termaltake actually expect that some part modding may be necessary to get the unit to fit in tight spaces and have used rigid, yet pliable plastic in some components.


    Once installed the results were obvious ? major decrease in temperature. Intel Processor Identification Utility now reports that the chip is running as expected 3.4Ghz and 800MHz System Bus.

If the PC boot and start I believe your processor is OK, it's very unlikely that a bad processor can start.
Normally the average temperature of a processor is between 40-50 degree C. Your processor is overheating and it will not last too long.
Please look at the link here below
and see if you can reconize your processor. The number on the left is the same number printed on your processor (You have to remove the fan again).
As a second test I suggest you to download the Asus manual of your motherboard and verify that you don't have any jumper that you are missing.
If you want to post the motherboard type I can further help you.

Is the ms 6540 motherboard compatible with the asus p5s800-vm

what u mean compatible? if u mean u want to change your ms 6540 to Asus P5S800-VM, then i tell u it cannot be done.
first thing that u look when to change mainboard is SOCKET type... ms 6540 have socket type 478 and asus p5s800-vm have socket type LGA775. thats mean your old processor cannot be use in asus. socket 478 is older than LGA775.
So if u want to change your mainboard for ASUS P5S800-vm, then u need to change your processor to... about RAM socket and VGA socket, ms 6540 have same type with ASUS P5S800 (DDR400) so u dont need to change your RAM and VGA (if u use external VGA)
hope this useful, regards.

I have an ASUS P4T-E motherboard and looking for info regarding; max. processor speed and max RAM capabilities. Can you assist????

Looks like this motherboard is capable of supporting PC800 ram and the general maximum processor speed is decided by whether the processor can fit the socket on your motherboard, as they don't make processors that are incompatible with the same socket. Thats is the whole idea of the CPU socket system.

The spec and more advanced information for you motherboard can be found here:

Dear Sir, my mother board d101 has been damaged can i use of p4sd m/b insted of that while i want all rest parts remain using i dont want change ram,SMPS, Proccesser etc.

fbhushan, the Intel D101GGC motherboard (Grand Country) supports;

1) Intel Pentium 4, Intel Celeron D, and Intel Pentium D processors that fit in an
> LGA 775 processor socket.

The Processor has the socket holes, and the processor socket (LGA 775) has the pins.
775 socket holes, and 775 pins.

The Front Side Bus (FSB) can be either 533MegaHertz, or 800MHz.

2) Supports DDR Sdram ram memory at either 333MegaHertz or 400MHz.
(PC2700 and PC3200, respectively)

Will support Up To 2GB of ram memory.
Has two ram memory slots. The maximum amount for EACH slot is 1GB

3) The SMPS used for it has,
A) One 24-pin ATX main power cable

B) One 4-pin ATX +12 Volt power cable,

The Intel D101GGC motherboard has Four SATA headers (Connectors) on it, so I'm going to assume you are using a SATA harddrive.
This would mean the SMPS you are using should have at least one SATA power cable.

It should also have an assortment of 4-pin standard Peripheral power cables.
(Misnomered as 'Molex')

The Asus P4SD (Motherboard chipset Intel 865PE) supports;

1) Intel Pentium 4 and Intel Celeron processors that fit in a > Socket 478 processor socket

The Processor has the pins, and the processor socket has the socket holes.
478 pins, and 478 socket holes.

Your Processor will NOT work.

The Ram Memory WILL work.

The SMPS MAY work.

I state MAY because the Asus P4SD motherboard uses a 20-pin ATX main power cable.

If the last four pins of the 24-pin ATX main power cable that you have on your SMPS right now, Do Not remove, you can Carefully cut them off. Wrap them up, and out of the way.
If you need guidance on this I can help instruct you.

You need an IDE (PATA) harddrive, or a SATA adapter card to use a SATA harddrive.

So there you have it sir.

I have an asus p48vx-x motherboard

you may check
1) your Intel pentium 4 3.2 GHZ cpu socket 478 processor #sl7nb what's FSB?( see on the chip surface, if 533 FSB can use but 800FSB could not match your motherboard if which is not support 800 FSB. that's why no display.
2) check RAM stick speed, try to increase a level, for example 266 to 333.
is this helpful please feedback thanks

yeah possibly, providing you,ve got the sys-bus speed to go with it, and plenty of Matched Speed RAM.
And a good quality heat-sink paste, heatsink and fan.
You,ll be thrashing the capicitors to the max, with everything running. but you,ll get 3-6 months probably.

Intel ASUS P4 845 GL Motherboard

Hi, For an ASUS P4BGL-VM Intel 845GL Chipset Ultra ATA100 MATX CPU Type: Intel Pentium 4 478-Pin (OEM), the Asus site specifies max of 2 x 184-pin DIMM Sockets support max. 2GB PC2100 / PC1600 non-ECC DDR or SDRAM memory but not "and". Personally, I find it more practical to install 2 X 1Gb rather than a single 2Gb. Hope this gives you some idea. Kind regards.
