The Intel Pentium III Slot1 650E
Nov 14, 2006 Not all Pentium III processors were manufactured in the new package. To support large installed base of Slot 1 motherboards Intel continued to release Coppermine Pentium III processors in Slot 1 package. These processors had the same performance.

In that case you would need to place 20 pentium iii coppermine slot 1 times more bets on blackjack than on slots. Sooner or later the FCPGA-Socket370 is supposed to replace Slot-1 completely. Today, all Pentium III CPUs, which make use of the Coppermine core (see table above) except the Giga-Pentium are.
Last October, Intel 'released' the Athlon competitor it so desperately needed. The only problem was, obtaining a Coppermine was almost impossible as was putting your hands on RIMM for an Intel i820 based motherboard. Today, nearly six months later, Coppermines are plentiful as are non-Intel chipset motherboard solutions. Why review an old Slot-1 based processor? In a nutshell, with the uncertainty of RIMM (or DDR SDRAM), motherboards such as the Asus P3V4X, and zero dedicated Coppermine PPGA motherboards, the overclocker has the opportunity to obtain screaming performance for very, very little money.
What This Review Is All AboutThe Chip |

For the overclocker, someone who wants to push their machine to it's absolute limits, this review is for finding out just how far a particular processor can go. The Celeron series of processors has proven to be not only cheap in general, but great overclockers due to the multiplier and FSB speed settings. Can the Slot-1 'big boy', keep up with arguably the best kept processor secret (the Celeron)?

The competition (FC-PGA Article)
In October 1998 at the Microprocessor Forum in San Jose, California, the first presentation of Athlon was made and some very interesting information was revealed. Probably the biggest one was the 200Mhz bus speed that the Athlon was slated to run on. Many were already wondering, and giving their personal theories online, on the upcoming processor. Or should we call it beast? But the Chip giant 'Intel' didn't take them seriously enough.
Then in 1999 AMD released the long-awaited Athlon CPU. The Katmai core had problems following the Athlon, and even the 'B' revision of the Pentium III Katmai couldn’t catch up with the Athlon. This was probably Intel’s scariest moment. But they never gave up, as we say, competition helps! A few weeks later, Intel finally released the long awaited Coppermine, which was supposed to ship in september 1999, but was delayed by a few months which comes to the 25th October 1999. This was the worlds first CPU running on a .18 micron process and having over 29 million transistors, and Intel finally had something to compete with the Athlon, even without running it on the delayed i820 - i840 Chipsets.
The 0.18 Micron Technology and L2 memory on chip. (FC-PGA Article)
The Pentium III Coppermine offers many benefits over its previous core (KATMAI). The Coppermine offers a 0.18-micron technology compared to the KATMAI core, which was distributed on the 0.25 process. This technique will allow the CPU to be distributed in a smaller size. The 0.18 process allows the implementation of over 3 times more transistors, which is a big move forward. Compared to the KATMAI core (9.5 million transistors) the Coppermine core uses 28.1 million transistors. This is due to the direct L2 implementation on the chip, which uses a large amount of space on the core. This offers many other benefits over the 0.25 process, one of the primary ones being lower voltage use. A FC-PGA Coppermine chip uses 1.60volts compared to the cartridged version of the Katmai, which uses 2.0 volts. Even when compared to a cartridged Coppermine, which at 1.65 volts, is 0.5 volts more than the FC-PGA. This will end up requiring less cooling and keeping the CPU cooler. Pyqt5 signals and slots example pdf. And as we step up to the 0.18 process, overclocking is a very good possibility. As you may already heard, the Katmais are already pushing their limits. The 0.18 process won't limit us in that scene anymore. A simple 550E can do at least 682 MHz (124 FSB x 5.5) with a simple heatsink. The direct L2 implementation is another big improvement. With the release of the Pentium III in February 1999, Intel decided to use their old strategy on the L2 memory, keeping it separated from the core. This was mostly because of a lower cost of production. The Coppermine includes 256k of L2 memory implanted in the chip, running full speed. Even with the KATMAI 512k of L2 cache (half-speed) the Coppermine runs faster with 256k of full speed cache.
Associated Equipment
Without the right (stable) gear, overclocking is a rather fruitless adventure only ending up in frustration. Before you run out and grab any chip suitable for overclocking, you must ensure that the rest of your associated hardware can handle all the aspects of forcing your slab of silicon to run at 'illegal' speeds.
For this test, I chose the Abit BE6-II motherboard, the Maxtor 30.7GB ATA66 HD, a 128MB strip of Mushkin CAS3 PC133 SDRAM and a PowerMan (Sparkle) 235 watt ATX power supply. Your choice of video cards will have a dramatic effect, due to the presence or lack of the magic 1/2 AGP multiplier. Of course, if you don't require an AGP card, various Voodoo 3 PCI solutions exist to get you stable at the 133 MHz FSB.

Our Slot-1 sample was manufactured in the first week of 2000. It's important to note that this is the boxed or retail version of the processor with the factory 3 year warranty and factory heatsink fan. It was birthed in Malaysia and has a default core voltage of 1.65 volts. With more radical cooling solutions, I'm convinced that higher frequencies could be reached at the sacrifice of added expense and noise.

This article is part of the CPU socket series |
Slot 1 refers to the physical and electrical specification for the connector used by some of Intel's microprocessors, including the Pentium Pro, Celeron, Pentium II and the Pentium III. Both single and dual processor configurations were implemented.
Intel switched back to the traditional socket interface with Socket 370 in 1999.
With the introduction of the Pentium II CPU, the need for greater access for testing had made the transition from socket to slot necessary. Previously with the Pentium Pro, Intel had combined processor and cache dies in the same Socket 8 package. These were connected by a full-speed bus, resulting in significant performance benefits. Unfortunately, this method required that the two components be bonded together early in the production process, before testing was possible. As a result, a single, tiny flaw in either die made it necessary to discard the entire assembly, causing low production yield and high cost.[2]
Intel subsequently designed a circuit board where the CPU and cache remained closely integrated, but were mounted on a printed circuit board, called a Single-Edged Contact Cartridge (SECC). The CPU and cache could be tested separately, before final assembly into a package, reducing cost and making the CPU more attractive to markets other than that of high-end servers. These cards could also be easily plugged into a Slot 1, thereby eliminating the chance for pins of a typical CPU to be bent or broken when installing in a socket.
The form factor used for Slot 1 was a 5-inch-long, 242-contact edge connector named SC242. To prevent the cartridge from being inserted the wrong way, the slot was keyed to allow installation in only one direction. The SC242 was later used for AMD's Slot A as well, and while the two slots were identical mechanically, they were electrically incompatible. To discourage Slot A users from trying to install a Slot 1 CPU, the connector was rotated 180 degrees on Slot A motherboards.
With the new Slot 1, Intel added support for symmetric multiprocessing (SMP). A maximum of two Pentium II or Pentium III CPUs can be used in a dual slot motherboard. The Celeron does not have official SMP support.
There are also converter cards, known as Slotkets, which hold a Socket 8 so that a Pentium Pro CPU can be used with Slot 1 motherboards.[3] These specific converters, however, are rare. Another kind of slotket allows using a Socket 370 CPU in a Slot 1. Many of these latter devices are equipped with own voltage regulator modules, in order to supply the new CPU with a lower core voltage, which the motherboard would not otherwise allow.
The Single Edge Contact Cartridge, or 'SECC', was used at the beginning of the Slot 1-era for Pentium II CPUs. Inside the cartridge, the CPU itself is enclosed in a hybrid plastic and metal case. The back of the housing is plastic and has several markings on it: the name, 'Pentium II'; the Intel logo; a hologram; and the model number. The front consists of a black anodized aluminum plate, which is used to hold the CPU cooler. The SECC form is very solid, because the CPU itself is resting safely inside the case. As compared to socket-based CPUs, there are no pins that can be bent, and the CPU is less likely to be damaged by improper installation of a cooler.
Following SECC, the SEPP-form (Single Edge Processor Package) appeared on the market. It was designed for lower-priced Celeron CPUs. This form lacks a case entirely, consisting solely of the printed-circuit board holding the components.
A form factor called SECC2 was used for late Pentium II and Pentium III CPUs for Slot 1, which was created to accommodate the switch to flip chip packaging.[4] Only the front plate was carried over, the coolers were now mounted straight to the PCB and exposed CPU die and are, as such, incompatible with SECC cartridges.
Historically, there are three platforms for the Intel P6-CPUs: Socket 8, Slot 1 and Socket 370.
Slot 1 is a successor to Socket 8. While the Socket 8 CPUs (Pentium Pro) directly had the L2-cache embedded into the CPU, it is located (outside of the core) on a circuit board shared with the core itself. The exception is later Slot 1 CPUs with the Coppermine core which have the L2-Cache embedded into the die.
In the beginning of 2000, while the Pentium-III-CPUs with FC-PGA-housing appeared, Slot 1 was slowly succeeded by Socket 370, after Intel had already offered Socket 370 and Slot 1 at the same time since the beginning of 1999. Socket 370 was initially made for the low-cost Celeron processors, while Slot 1 was thought of as a platform for the expensive Pentium II and early Pentium III models. Cache and core were both embedded into the die.
Slot 1 also obsoleted the old Socket 7, at least regarding Intel, as the standard platform for the home-user. After superseding the Intel P5Pentium MMX CPU, Intel completely left the Socket 7 market.
