How to overclock Celeron 2.0 GHz to 3.0 GHz?

[Danel]

I am here to check how to overclock Celeron 2.0 GHz to 3.0 GHz? Earlier, when everything was better, because the Celeron enjoyed after the first unsuccessful launch of a model with no L2 cache with an excellent reputation. Acceptable speed for a very low price helped the CPU coupled with the often excellent overclocking an honorable reputation. The models based on the Pentium III, only reached by the FSB (100MHz instead of 133MHz), and the disabled hardware prefetch unit and no longer distinguished by the memory, the performance of the new Celerons standards. Please provide some more comments on this topic.

However, the PIII, and thus its budget offshoot have resigned - the P4 determines the market and, in recent months, there is also a Celeron-branch, who has shaken off the initial still in use Willamette core, and now in the guise of the Pentium 4 therefore comes with 2.8 GHz created nC1-stepping. Only the L2 cache is 128KB with less by 75%. Although many different processor cores Celeron had heard the name, they all have one thing in common: they are invariably allowed to castrate Pentiums, the Mendocino times out of it. To sell a "Pentium" under the Celeron-label, robbed it for a major part of the essential L2 memory and missed him mostly a low-clocked system clock (front-side bus). While the Pentium III has already worked with a FSB of 133 MHz, it increased that the Celeron from 66 to 100 MHz. This generalization applies of course to the new Celerons also that the socket 478 are provided for, and on the NetBurst architecture of the Pentium 4 based.

While the first models with 1.7 and 1.8 GHz or the Willamette-128 core based on Intel is taking with the 2.0 GHz Celeron is now also switching to the finer manufacturing technology, commonly found on the Pentium 4 in early 2002 did. This makes it possible for Intel, the processor clock without major thermal problems significantly increase and thereby develop a low power loss. The fine production and thereby reduce the traces also the signal quality has improved, thereby one could also lower the CPU voltage slightly from 1.565 to 1.525 Volts. While the output voltage is totally uncharacteristic of the Willamette core, the Pentium 4 was here operated at 1.75 volts, the 1525 the new Celerons are typical of the new Northwood core. Even at first glance it is clear that the new Celeron is up by 75% in the smaller L2 cache, a real Pentium 4. The particulars of the transistor size and die size of Intel, however, is silent. Probably there are no deviations from the true Pentium 4, up to the fact that part of the L2 cache is disabled and thus not all transistors are used.

Higher clock speeds are all well and good if only they were not the problem with the increasing power consumption as well. For what can the processors to run current through their circuits will inevitably converted into heat. The world would be nice if there was (caused by the ohmic resistance of the lines), no loss of performance? Unfortunately, we are not ready and so must the processor manufacturers to prevent their occurrence, that next race car, a 100-watt-eating monster. Despite a markedly higher clock, it uses about 10 watts less than the old model with Willamette core. Seldom is a new processor as much overclocking potential has to be related to how the new 2.0GHz Celeron. Because in it, the processor core and the stepping of a much higher clocked model, namely the 2.8GHz Pentium 4, is used, and the Celeron for these clock rates is perfect.

Since the processors from Intel known to all processors are set to their Multiplication, the Celeron it is set to 20x, and a change of the multiplier via the BIOS is not possible, then the only way to increase the front-side bus. Since all current motherboards for Socket 478 offering a front-side bus of 133 MHz, without having to run this other components beyond their specifications, we have tried our luck first with 20x133MHz, ie, a processor speed of 2.66 GHz, an increase the processor voltage was not necessary. As memory speed, we selected 166 MHz (DDR333). An operation using a standard Intel boxed cooler introduced us any stability problems. All benchmarks were run without interruption or hangers are. In general, this seems the perfect clock for the Celeron and the motherboard components to be.

But the Celeron can do more. To 2.8 GHz, we could easily have increased processor power with standard cooling go on. The front-side bus was allowed to wade in this case 140 MHz. Thanks to our motherboards to let the clock of the AGP and PCI bus lock so that eventually were operated only the processor and the memory controller outside the prescribed framework. Even the Celeron 3.0GHz agreed with boxed fan in Windows to turn. However, here the system was completely stable, to mean not as - as a running Cinema 4D, FlaskMPEG, and only PCMark2002 Lightwave with an improved cooler in the form of water cooler Magnum stable. In Sysmark back we even had a front-side bus of 149 MHz, because Adobe Premiere wanted to run under any circumstances. However, one should not forget that the store was run with DDR400, which is also far from without. A successful power-on self-test was possible the way to 3.17 GHz with appropriate cooling. But either way the results obtained with the Celeron are impressive. An increase above 800 MHz clock, so 40 percent was with the Boxed cooling without loss of stability possible and even with a 50 percent increase in stroke work was largely possible. In all this, one should keep one fact in mind: a Pentium 4 with 2.8 GHz and can be C1-Stepping sometimes be run stable at 3.2 GHz and air cooling. It is thus quite clear that the Celeron is not just get the purest and best processor cores are used.
