Intel Pentium 4 531 (3.

0GHz) — bad batch

Through the efforts of unknown overclocking gods, new processors appear on sale at the speed of heterotrophic organisms multiplying spores after one of the types of precipitation. We just had time to consider
Intel Pentium 4 516 (2.93GHz), how it became possible to test their older comrades — Intel Pentium 4 531 (3.0GHz) processors. All three processors we got were marked
SL8HZ , were assembled in Malaysia, and their nominal voltage is 1.4 V.

Processors with a number that differs by one from the base model (505⇒506, 515⇒516, 530⇒531) can be taken without any fear, even without looking at the marking. We are guaranteed to get a processor based on the Prescott core revision E0 and supporting EM64T (x86-64) technology. There may be slight differences between processors, for example, the Intel Pentium 4 516 processors that we recently tested were equipped with the Thermal Monitor 2 (TM2) power saving and thermal protection function, while our current Intel Pentium 4 531, judging by the RightMark CPU Clock Utility are content with TM1. However, during today’s test, things did not come to throttling, so in this case, the specific mechanism for implementing overheating protection is not so important to us.

The test system has not changed since the previous tests, it was an open bench, including the following components:

  • Motherboard — Asus P5WD2 Premium (i955X), rev. 1.02, BIOS 0422
  • Video card — NVIDIA GeForce 6800GT (16p/6v, 350/1000 MHz)
  • Memory — Corsair TWIN2X1024A-4300C3
  • Hard Drive — Western Digital Raptor WD740GD
  • Cooler — Zalman CNPS7700Cu
  • Thermal Grease — Zalman
  • Power Supply — CoolerMaster RS-450-ACLY (450W)
  • Operating system — WinXP SP2.

The launch of the first processor was uneventful, but its high temperature inspired fear. Immediately after the start, even before any tests, it was very close to 60°C, according to the BIOS readings of the motherboard. The Zalman CNPS7700Cu cooler is difficult to install incorrectly, but just in case, it was reinstalled, which, however, did not lead to a decrease in temperature. It’s just that the processor got abnormally hot even for Prescott.

Our goal is 4 GHz and above, but with this processor it is simply out of reach. He was able to boot Windows only at 250 MHz FSB, and tests in S&M 1.7.2. passed at a bus frequency of 240 MHz, warming up to 70.6 ° C.

The second processor has pleased us in comparison with the first one, if, of course, we can rejoice at successfully passed tests at a rather modest frequency of 250 MHz.


The temperature rose to 72.3°C, but there was no throttling. I remind you that the stand is open, the temperature is quite high, and in a closed case it will be noticeably higher. Under such conditions, I did not experiment with increasing the voltage applied to the processor, and limited myself to «achieving» 250 MHz FSB.

All processors are brothers that are related to each other in different degrees. If you look from this point of view, then the second and third processors are almost twins. The serial number of the third processor was only three times different from the second one, but in terms of its overclocking abilities, it was more like the first one, since it could pass the test only at a bus frequency of 240 MHz. But, unlike the first one, its temperature remained within reasonable limits and never exceeded 65.6°C.

So, the statement remains true — by purchasing Intel Pentium 4 531 (3.0GHz) processors, you automatically get support for 64-bit technologies and E0 stepping. However, it is far from certain that you will be able to overclock them in the same way as early stepping Prescott processors or even the best examples of Northwood.
