I want to get a FASTER Processor for my system but don't know how to determine which one.

I assume I am limited by my Motherboard Type - I don't know what other limits exist.

I would like to upgrade to "at least" a 500MHz processor.


Custom-built System ( Nimble Explorer XP )
*** Distributor Out-Of-Business ***
Intel Pentium II, MMX, 300MHz Processor
ENPC EP-KL21 v1.3 4PCI 3ISA Motherboard
96MB SDRAM ( Upgrading to 384MB SDRAM )
Quantum Bigfoot TX 12GB UDMA33 Hard Drive
1.44 Samsung Floppy Drive
Award BIOS ( 1998 )
ATI 3D Rage Pro AGP 2X 4MB SGRAM Video Card (using 4.11.2560 Turbo Driver)
Pioneer DVD-ROM ATAPI DVD-A02X 0105 CD_ROM Drive
(ADDING: Yamaha CD-RW 24x/10x/40x Internal Dive )
56K-Flex Rockwell PnP Internal Modem
PCI / DCS S727 Sound Card / Ensoniq AudioPCI
Wave 600 Sub-Woofer & 2-Speakers Sound System
Multimedia Microphone
PS/2 104-Key Win95 Compatible Keyboard
Microsoft IntelliMouse Trackball Mouse v4.0
VGA / MPEG / 95 OSR2 Video Chip
Smile 17" 0.26dp Digital Color Monitor
ATX Mid-Tower Computer Casing
Windows 95-C ( 4.03.1214 )
DirectX 8.0a
AOL 7.0 Internet Connection
MSN Internet Access 5.6.960 Internet Connection
Internet Explorer 5.50.4807.2300
Lexmark EX2 7200V Color Inkjet Printer
UMAX Astra 1200S Flat-Scanner


How do I begin to figure out how to upgrade my PROCESSOR ????

Thank you for any help or guidance.

I hate to be the bearer of bad news, but unless you are planning to use a Slot 1 celeron, you options are limited to 333 P2 mhz or under.

See for specs on your board.

Supports for a single Intel Pentium II or Celeron processor
Supports 66/75/83 MHz host bus clock, selectable by BIOS
Slot 1 connector
Chipset (Intel 440LX AGPset and PCI/IDE)

An LX chipset won't support a 100 mhz FSB (front side bus).

The Celeron is an option, however Slot 1 Celerons are kind of rare anymore. The later models were released as a Slot 370. You can buy Slot 1 to Slot 370 adapters.
Also keep in mind that any Celeron over 533 mhz is going to run on a 100 mhz FSB - not supported by an LX board.

My best advice ? If you really want to upgrade past 500 mhz, you are going to have to replace your board and processor anyway, I would invest a little more money and go for a Pentium 4 or an Athlon XP. They cost a bit more, but you won't have to upgrade again as soon.

As a final note, most of the components that you listed were fine in the mid 90's, but have become dinosaurs since. A complete system might be a solution. I don't like pre-built systems, because I like to customize my machines, but it might be worth checking out - if the prices are right.

Good Luck

Don't forget that after 500 MHZ, the celeron went from PPGA to a FCPGA Architecture at 66 MHZ FSB to the 800MHZ celeron which as Matt pointed out is at 100FSB FCPGA. So even to run a 533 Celeron you would not only need the Slot to socket adaptor but you would also need one that has onboard Vregulation for FCPGA or flipchip.

Thank you MATT and E.S.:

I wondered when the time would come to get a whole NEW system.

I can see that NOW is the time. I am thinking of returning my "unopened" Yamaha CD-RW drive and put that $210 towards a NEW system.

Thank you for your "knowledgable" reply and important information.

I think I'll try to play with the "overclocking" idea for awhile first (after backing-up everything") and when my processor has had it - I'll go for the NEW system.

Gratefully yours,

Hello again:

I just wondered - could I use the following PROCESSOR on my present system . . .

Introduction date = April 26, 1999
Clock speeds = 466 MHz
Number of transistors = 19 million ( 0.25 micron process )
Cache: 128KB on-die packaging = Plastic Pin Array (PPGA), 370 pins
Bus speed = 66 MHz
Bus width = 64-bit system bus
Addressable Memory = 4GB
Typical use = Value PCs

Could my present system reach 466MHz with this CELERON and the ADAPTER you mentioned ?

If I stay UNDER 500MHz and use that ADAPTER - could I still use my present motherboard ??

Thanks for the help.

A 466MHZ PPGA Celeron should work fine, the only issue might be whether the bios will detect it as a 466 MHZ, which, in my experience, is a cosmetic issue anyway as all new celerons are multiplier locked. Which type of adaptor are looking to get? Jumperable I hope.

Hello E.S.:

I don't know anything about the "ADAPTER" I should get. I was referring to the "adapter" MATT WESTON mentioned in the beginning of this POST . . . "Slot 1 to Slot 370 Adapter."

Do you think I can find a (SLOT 1) 466MHz Celeron Processor or will I have to get this ADAPTER ( I don't know if IT is "jumperable." )

Can you suggest the correct adapter for the Celeron 466MHz processor on my system?

Also, I am unsure of the meaning of "cosmetic issue" pertaining to the BIOS not detecting the processor as 466MHz. Does this mean there IS something I can do - if the BIOS doesn't detect the 466MHz . . . or what ??????

I realize my computer components are ancient - but they are still kicking and I'd like to get another year out of them if possible.

Thank you for your help and info - lost without it.

The slot to socket adaptor is also what I was referring to as well. As to proper CPU detection, your mainboard bios determines what is shown at boot up, if a 466MHZ cpu is installed, but the bios only has 433 listed, the cpu may post as a 433 but still run at 466MHZ, a cosmetic issue with older LX boards. Slot1 466 Celerons are rare but available, but cost more than the socket 370. Asus and a few other manufacturers use a jumperable configuration with onboard Vregulators for running PPGA or FCPGA. The Asus is called Smart Slot1 series and you can probably pick one up for around 10 bucks.

OK - E.S.:

Thanks for all the help and information.

I'll use your info and see what I can do.

Gratefully yours,
