>>>>Are you using a Pentium precessor. The Intel chipset used with these processsors can only cache the 1st 64MB of memory. Since the operating system loads into high memory it runs uncached and the system crawls. If you are using a Pentium Pro or Pwntium II the limits are 4GB or 512MB respectively. The only way to speed up the Pentium is to remove the extra memory and hope you can return it.

>>>Thanks Steven,
>>>Yes its a Pentium 166
>>>No I cant return it. OOPS

>>See my reply to Steve - it is not a limitation of the processor chip, but the support chipset on the motherboard. Changing the processor will not change the L2 cache behavior.

>>If the motherboard is based on the 430HX chipset, there may be an open socket that will accept an additional cache memory chip; adding the additional cache chip, called tag RAM, will allow caching of up to 512MB on an HX motherboard. A few HX motherboards use COAST (Cache On A STick) modules; most motherboards that do will either accept a second COAST module or a larger COAST module with the extended tag RAM. You'd need to check the make and model of motherboard to find this out - in addition to
Tom's Home Page,
Spumador's has a comprehensive list of motherboard and BIOS vendors, and an incredible number of motherboard manuals on-line.

>>The Pentium and AMD are socketed chips that mount in a ZIF Socket on the motherboard. Most TX chipset motherboards will support 200MHz processors; a few will support 233MHz Pentium MMX (P55C) and AMD K6 processors, but may require a BIOS upgrade to do this. The K6-2 really needs one of the newer chipsets like the Via MVP3.
>>
>>If you do elect to replace the motherboard, make certain that you purchase a new motherboard that uses the same form factor as the existing board. Older motherboards are AT form factor; the newer ATX form factor boards (this includes virtually all Pentium II motherboards) will not fit properly in cases designed for AT form factor without having to drill new mounting holes for the motherboard, and ATX motherboards use a different power supply connector than the AT form factor boards. Also, make sure that a new motherboard will accept the memory you have now - some of the newer boards will only accept 168 pin SDRAM or EDO DIMMs, so 72 pin SIMMs might not be usable with a newer board.
>>
>>IMO, it probably is not worth investing more money in upgrades for a 166MHz Pentium at this point. If you replace the motherboard, I'd also replace the processor at the same time.

Great! The right hardware can make a world of difference.
>My hardware guy did not know about the HX board limitations.
Not surprising, since you need to actually look into the details of the chipset a bit to realize that even though the capability exists, it requires some specific steps (in this case, the additonal extra RAM chip) to take advantage of it.
>I suppose that I will be real happy until I get to see a 600meg K7 then it will all start again.
Don't remind me; I'm looking at retiring one of my LX boards once the Pentium III situation gets a bit clear and I can settle on a motherboard.
Right now, I've got an overwhelm desire to upgrade my monitors; I picked up a ViewSonic 19" (the PS790, which uses less desk space than some 17" monitors) and swapped it in on my main development box. VFP at 1280x1024x32 bit color is wonderful, especailly in the Form Designer, or using the debuuger...
