Pentium 4 not running full speed, cpu or motherboard issue?

[idata]

I have an old system that I've just noticed isn't running the cpu at the speed it was designed.

CPU is a Pentium 4, 2.4GHz, and identified as such with the Intel cpu id program with following details:

===================================

Intel(R) Processor Identification Utility

Version: 4.22.20100224Time Stamp: 2010/08/12 23:54:03Operating System: 5.1-2600-Service Pack 3Number of processors in system: 1Current processor: # 1Active cores per processor: 1Disabled cores per processor: 0Processor Name: Intel(R) Pentium(R) 4 CPU 2.40B GHzType: 0Family: FModel: 2Stepping: 7Revision: 37Maximum CPUID Level: 2L1 Trace Cache: 12 KµopsL1 Data Cache: 8 KBL2 Cache: 512 KBPackaging: FC-PGA2Enhanced Intel SpeedStep(R) Technology: NoMMX(TM): YesIntel(R) SSE: YesIntel(R) SSE2: YesIntel(R) SSE3: NoIntel(R) SSE4: NoEnhanced Halt State: NoExecute Disable Bit: NoIntel(R) Hyper-Threading Technology: NoIntel(R) 64 Architecture: NoIntel(R) Virtualization Technology: NoExpected Processor Frequency: 2.40 GHzReported Processor Frequency: 1.80 GHzExpected System Bus Frequency: 533 MHzReported System Bus Frequency: 400 MHz

===================================

Note that the expected FSB is 533, but it's running at 400, and this is apparently the reason it's running at 1.8GHz vs. the rated 2.4.

Motherboard is an ECS P4VXASD2+

BIOS is latest available for it, and while I've had this since new, never actually noticed or checked to see if it ever ran at 2.4GHz, I suspect not.

BIOS shows it running with 400MHz FSB, but it also says the cpu is Frequency LOCKED, so cannot change the FSB setting to 533, even though all the specs say the motherboard supports 533.

Question is, is this a CPU issue (locked at 400MHz FSB?), or a motherboard issue mis-recognizing the cpu as being locked and set to run at 400MHz instead of 533?

Thanks for any tips.

Hello;

The problem can be related with a desktop board and processor compatibility issue, is not common to have a 'locked' option under the processor in BIOS, it can be that the desktop board can run your processor at 400 mhz only, I do recommend to contact the desktop board manufacturer for any BIOS settings that you may need to change.

Also, if you need to determine that your processor is properly detected by your desktop board I recommend you to download and the install the Intel(R) processor Identification utilty, you can download this application at the following url:

Thank you very much. I already ran the processor ID utility from Intel and it correctly identifies the processor, and is what showed it was running with a 400MHz FSB, hence my query.

I've got an inquiry at the mbd mfg as well.

Thanks!
