Overclocking of Pentium 4 with 533 MHz FSB

[Xanty]

While the fan base of the new AMD still manufactured in 0.13 micron processor core, code-named Thoroughbred waiting for Intel can be transferred with its 0.13-micron Pentium 4 processors already to the next stage of evolution. I want some information about the new Pentium 4 models, which are operated with a front-side bus of 133 MHz or 533 MHz effective by the quad-speed bus and now available with clock speeds of 2.26 GHz to 2.53 GHz in the trade are. After the Pentium 4 could hit 2.4 GHz and a front-side bus of 400 MHz Athlon XP 2000 + with a real clock of 1.66 GHz in almost every area of our extensive benchmark suite, this time could be an Athlon XP say 2100 + against Intel's new high-end processors for the desktop market, the Pentium 4 2.4 GHz and 2.53 GHz with a front-side bus of 533 MHz. Now I am expecting that you members will response me by providing some notes on overclocking of Pentium 4 with 533 MHz FSB.

The new Pentium 4 is based on the products manufactured in 0.13-micron Northwood core, which features a 512KB cache and we looked closer in the past two times. In this context, Intel often had to put up with criticism that they wanted to push the Pentium 4 implementation, only the clock speed up, without breaking new speed records. On one point, the critics have certainly right here: A running at 1 GHz Pentium 4 would be significantly slower than a 1 GHz Pentium III or AMD Athlon. At a clock of 2.4 GHz, which reached the Pentium 4 with Northwood core without major thermal problems, it is clear a completely different result. With the introduction of the 2.4 GHz Pentium 4 on 2 April, Intel increased the processor speed of 200 MHz and permeable is now with the 2.53 GHz Pentium 4 133 MHz or create one on it. In light of these major steps should be clear that Intel's largest competitor, the AMD Athlon XP, has been left far behind. Because AMD was the introduction of the Athlon XP 2100 + processor with a real clock of 1733 MHz only 66 MHz compared to the Athlon XP 2000 + on the top with separating the two fast processors from Intel and AMD currently no less than 800 MHz.

From Intel's perspective, the idea of Netbrust architecture on 20.11.2000 so it was a resounding success - or has become a. This has repeatedly been mentioned in this architecture can be outlined six key words :

• Hyper Pipelined Technology
• Rapid Execution Engine
• Advanced Dynamic Execution
• Execution Trace Cache
• Quad-speed system bus
• Streaming SIMD Extensions 2 (SSE2)

Anyone who would expect with a 533 MHz Pentium 4 revolutionary innovations, should therefore be somewhat disappointed. Also, the processor stepping has not yet changed. Currently, there is the Northwood core, only the NB0 stepping, which is equipped with 23 known bugs.

Together with the introduction of the new Intel Pentium 4 processors as already posted the new e-i850 chipset with Rambus support mentioned in the race. This chipset, we have devoted a separate article in which we also respond specifically to the new features of the chipset. In addition, Intel will soon introduce a slightly revised i845 chipset, which will be named i845-E and is also designed for the new Pentium 4. Besides, Intel has yet SiS with the SiS645DX a FSB533 compatible chipset in the program. Also, VIA has introduced the P4X333 a suitable chipset. Since, however, remains the litigation between VIA and Intel about the licensing of the Pentium 4 bus are not known, will initially probably only have VIA motherboard with its own brand VPSD relevant products in the program.

With our recent processor reviews, we have dealt with the overclocking though often in principle, our thoughts but not put into action. Since we have this time for our test processor in addition to the Intel motherboard that was used for all benchmarks, even the aforementioned P4T533-C motherboard from Asus was standing with his many overclocking features that we were now able to act themselves. It even we were surprised. The Pentium 4 2.53 GHz, we were able to operate here by air cooling (Intel boxed fan), without increasing Vcore to 2.85 GHz (19x150 MHz) is completely stable. The CPU temperature in this case was under full load 45 ° C, a perfectly acceptable value. The memory was running at 450 MHz in this case. No problem for our PC1066 modules are designed as standard for 533 MHz. to conduct the experiment, our Rambus with synchronous front side bus of 600 MHz, 32ns Samsung coped our modules do not unfortunately.

Even if the motherboard does not us to set a higher bar in the BIOS enabled, so this test does show impressive performance potential which lies in the Pentium 4. In light of this, it would be easy for Intel to increase the processor clock continuously at regular intervals to 3 GHz. So now we come to the most interesting part of this article. To evaluate the performance of processors, a slightly modified test system came to support the new Pentium 4 processors. As Intel i850 mainboard us e-reference board was named D850-EMV2 that has a special extra for a USB 2.0 controller from NEC. However, the board overclocked the processors a bit conservative, so that was the 2.53 GHz Pentium ultimately operated with approximately 2.52 GHz. For the screen output of our proven GeForce3 Ti500 Inno3D was responsible. We tested both with the official support PC800 Rambus, and with PC1066 memory, which should develop the full power of the processor.
