	Pentium OverDrive - Wikipedia, the free encyclopedia
		The Pentium OverDrive was claimed to enable 486 owners to upgrade their machines to Pentium performance, without the cost of having to replace the entire system.
		Furthermore, the OverDrive chips ran hot, and it was pointed out the DX4 based upon an older chip architecture clocked to a higher frequency, typically ran faster.
		OverDrives for the Pentium 75, 90 and 100 were also released (socket 5, 3.3v), running at 125, 150 and 166 MHz (clock multiplier of 2.5).

	Pentium Overdrive
		Pentium Overdrives were unlike 'normal' Pentium processors, which were designed to function with a fast 66 MHz or 60 MHz front side bus (apart from the 75 MHz version) as well as cpu sockets which did not appear on 486 motherboards.
		The Pentium Overdrive was provided as a means to give a Pentium-performance-level upgrade option for owners of 486 computer systems.
		To perform properly, the chips were dependent on sizable amounts of cache ram[?] being present on the motherboard; without it the Pentium Overdrive was only a trivial amount faster than a DX4.

	Pentium
		The original Pentium microprocessor had the internal code name P5, and was a pipelined in-order superscalar microprocessor.
		In early 5 volt 60 MHz and 66 MHz Pentiums, a problem in the floating point unit code when doing division was discovered in 1994 and is known as the Pentium FDIV bug.
		These early examples of Pentium processors were also known for their fragility and relatively high levels of heat-production.

	Intel 83MHz Pentium Overdrive (Site not responding. Last check: 2007-10-21)
		It won't turn your old PC into a full-speed Pentium: there are a number of technical difficulties in replacing a 486 with a Pentium, the most awkward of which being that the Pentium has a 64-bit bus whereas the 486's is only 32 bits wide.
		This means that a special version of the Pentium, the P24T, had to be designed to fit onto a 486 motherboard, and even then it requires a special socket.
		Finally, the Pentium has greater power and heat-dissipation requirements than a 486, which at the end of the day restricts the number of PCs in which this processor will really shine.

		Pentium OverDrive processors with MMX technology have been specially designed to provide an upgrade path to Intel's MMX technology for existing upgradable Pentium processor based systems.
		When upgraded, the Pentium processor is simply removed from the Socket 5 Zero Insertion Force (ZIF) socket and replaced by the Pentium OverDrive processor.
		The Pentium Pro was the first microprocessor not to use the venerable Socket 7 form factor.

	Processor Upgrading FAQ: Socket Upgrades
		The Pentium II is related to the Pentium Pro but instead of having its L2 cache integrated onto the chip, it is placed on the circuit board that the chip itself is mounted to.
		Pentium III chips come in 100 and 133MHz flavors with the 133MHz chips requiring a 133MHz capable chipset (such as the Intel 810e or 820 or VIA Apollo Pro-133).
		The later releases of the Pentium II and III chip have had their multipliers limited to what the chip itself is supposed to run at (a 300MHz chip has a maximum 4.5x multiplier).

		A good way to tell if a Pentium Overdrive CPU upgrade will work in your 486 is to look at the socket with the 486 installed and see if there is an extra row of pin holes in the socket.

		There is no reason why it wouldn't work providing the chip is made to work in a pentium pro board at 200mhz, the whole idea of an Overdrive chip is to boost the speed beond what the system was designed to do.
		However, Overdrive chips are usually quite pricy and more often than not you would be better off replacing the whole system with something faster, but hey if your getting them at a good price take a chance..
		An overdrive processor is a chip that would say for aguments sake take a board that can only do 200mhz and boost the speed by upto twice the speed or in this case 333mgz, the board it's self is still only outputting 200mhz but the chip ampliflys the power out put.

	Processor Upgrading FAQ: Processor Upgrades
		If a Pentium w/ MMX 200 or 233 only runs at 133 or 166MHz (verify this by running Wintune 97 or ctcm17a), the motherboard may assume the chip automatically pulls pin BF0 'high', and not bother to properly set the pin.
		The Intel Pentium II is an adaptation of Intel's powerful Pentium Pro chip, and uses a proprietary socket to connect to the motherboard.
		Like their Pentium Pro cousins, the Pentium II chips have 4 clock multiplier pins that are set at RESET to determine the internal multiplier the chip will use.

	AnandTech: Intel Pentium II OverDrive
		A problem with using the Pentium II core on the OverDrive processor was that there would be no way a Pentium Pro user would agree to making an upgrade to a processor whose cache ran at 1/2 clock speed while their aging Pentium Pro ran its L2 cache at full clock speed.
		Owners of the Pentium Pro 200 with 1MB of L2 cache may want to think twice before considering this upgrade, as the Pentium II OverDrive is outfitted with 512KB of L2 cache which should be an improvement for most Pentium Pro users as the 256KB processors were quite popular.
		The Pentium II OverDrive, although officially offered in two flavors, a 300MHz and a 333MHz version, is essentially a single 333MHz processor with L2 cache that is intended to run at 333MHz.

	CPU Guide: modern classics
		Intel did this with 486 systems and the Pentium Overdrive, then repeated the scam with Pentium Pro systems and the Pentium Pro Overdrive, which was actually a version of the Pentium II repackaged to plug into the Pentium Pro's Socket 8 — the cache module sat on top of the CPU itself, under the fan.
		The Pentium is one of the all-time classic CPUs, and though it seems strange to think of it that way now, the 100 was one of the all-time classic Pentiums.
		The other nice thing about the Pentium family was that if you were working with an older motherboard of doubtful compatibility, they were more likely to be straightforward and trouble-free than the early AMD and Cyrix parts.

		With a street price of approximately $400, Intel's first Pentium OverDrive chip, which was released earlier this year, offers a moderately appealing solution for upgrading your PC's processor from a 25-MHz 486 to a 63-MHz Pentium.
		BYTE's cross-platform BYTEmark CPU/FPU benchmark tests (see the figure) on the new 5-V, 83-MHz Pentium OverDrive show that this upgrade chip will boost an Intel 66-MHz 486DX2 PC (or any other PC with a 33-MHz I/O bus and a #3 socket) up to performance levels that are slightly less than that of a 90-MHz Pentium.
		The 83-MHz Pentium OverDrive chip is an inexpensive and effective upgrade if you want to squeeze more power out of your PC instead of taking the plunge of purchasing a new system.
