Should I over-clock my Processor?

[wyz135]

I have a problem, when I went in into the BIOS setup and checked the CPU temperature, the temperature seems to be stucked at 50 degree celsius and when I go into the Over-Clocking feature Menu, they allow me to over-clock by 5%, 10%, 20% and 30%. Since my CPU temperature is stuck at this temperature, should I over-clock?

You must have in count that when you check temps in bios menus the processor is completely idle, so they are going yo be very low and when you run the s.o and applications this temps are going to rise a lot . You should test it running a cpu stressing aplication. I usee CPU BURN-IN to stress the cpu load, and Nxsensor to test the temps (maybe are inacurate but you can see the degrees temp increase).. I have 2 asus mobos that let you overclock the same way you say,5%, etc.., but they leave the ram frequencies overclocked too, and i preffer not run the risk to damage the ram modules. I do overclock if my temps are under the max temp supported by the processor at the manufacter specifications, never reaching that limits and staying some degrees below.

So i tried using the CPU BURN-IN, but when i start testing, nothing special appear, i used ASUS PROBE II to check my CPU temperature, the temperature just keep going up, when the test is over (I have set it to 15min) They did not say any results, just say CPU test completed successfully . So how should I use this software?

Unless it's a C2D CPU , don't bother , it wont do much .

It depends on what CPU you are using...

50 c idle sounds like normal p4 prescott temps to me...

Cedar Mill will produce much more heat because of HT technology

welllll... what kind of core have you got?

Intel Pentium 4 HT Cedar Mill 631+

gotta agree with radiator, it wont add enough performance to offset the potential instability. Not to mention the extra heat in your case.

No, after my getting new heatsink fan, Cooler Master Hyper TX2, it's max temperature is just only 48c with HT enabled. And overclocking my processor by 600MHz (for example) is not just only giving me a 600MHz boost, it's more than 600MHz because of HT.

For more information HT is hyper-theading, enables your OS into thinking your PC is hooked up by 2 processors

I know what hyperthreading is, and it is usually abbreviated as HTT for HyperThreading Technology.

HT is used for hypertransport which is used in AMD's socket 754 and beyond for bi-directional communication along the equivalent of a fsb, the hypertransport bus.

From what I know of P4 architecture, the primary limit of the CPU is in the bus. Having 2 seperate threads running on the same clock probably won't affect actual performance in application.

30% improvement of performance promised by intel. I've tried 3D Mark 05 to determine whether is there really improvement or not, I get only slight improvement, so it proved that getting 2 threads to run on a single core really did improved gaming performance, but not for applications. But after some overclocking, I'll get improvements of higher percentage. I've over-clock my processor to 4GHz, max load temperature is 60 dgrees (Worth getting the CoolerMaster Hyper TX2) , but not so sure about stabilty, still currently testing. If I have the money, I rather get a Core2 Duo rather than overclocking to compete with a Dual Core processor, but I know it's difficult because it's greatly improved by the additional SSSE3 instruction set.

A 3GHz single core perform better than 2GHz dual core in some games, because some games doesn't ultilize both the cores. I have this feeling that my P4 processor is powered by a single strong core and Dual Core has 2 weak cores working together

65/45nm architecture makes things smaller and more efficient.

The core2 solos perform at a level beyond the p4s. Good luck finding a solo anymore though, Dual-core cpus are much more future-proof.

That's why Cedar Mill perform better than Prescotts. Core2 series outperformed the P4s just because of the additional SSSE3 (aka SSE4) instruction set.

Even the original core solos (remember those?) outdid the p4s at a lower clock speed.

Because of the additional SSSE3 instruction set, Take PentiumD vs Core2 Duo as example, they are both Dual-Cores. But in gaming application, a 3GHz (for example) P4 can perform better than a 2GHz Dual-Core sometimes, anyway what's P4s maximum most stable temperature? I'm getting 68 degrees sometimes.....

You're running fairly hot, but you aren't in danger until you hit 75*C

The original core series did NOT include support for ssse3, though it was in later Pentium Ds when they started using Yonah in the PD. The 32 extra instructions in SSSE3 are only useful if the program can use them.

P4s have gotten to 5+ghz on good watercooling, but they don't see huge performance increases at that speed.

Some games don't support dual cores, and a dual-core won't exactly double performance. It also depends on what series of dual core. The pentium D's and core duos had really big memory latency issues between the cores.

The P4 prescott was known to run stable oc'd at around 80c and the cedar mill is safe at 72-73, so you're probably good with that. Only a stress test can really tell though.
