: Hi

: I have a PC which has Pentium 166MMX processor.
: The manual says following :
: Pentium Mainboard

: supports P54C 75/90/100/120/133/150/166/180/200 MHz processors and Pentium P55C, Cyrix 6x86, AMD K5 CPUs with PCI IDE & Multi I/0

: Intel i430VX PCISet chipset

: Uses four 72-pin EDO/Page Mode SIMM modules auto banking in multiple config upto 128M.

: I installed a DVDROM but, hard to see a movies. I have 92M memory.

: I have following questions:

: 1. What is P55c that it says support ?
: a. Can I just buy a P233MMX CPU and install it ? Will it work ? Will I see any performance improvement in DVD watching ?
: b. Can I buy any higher speed CPU and install it ?

: 2. Does my board support PC100 memory ? If does should I replace my 92M EDO with 128K (if possible, more ??) PC100 ?

: Also, my BIOS ID is 430VX-02071997C-00
: Do I need to change my bios ? How ?

: Thanks in advance.

Your memory is 72pin FPM or EDO; PC100 is 168 pins. NOT interchangeable. Total usable memory is rated 128MB. You can use 4x32MB=128MB SIMMs. You probably have 2x32 + 2x16 = 96MB, maybe video or DVD is using 4MB.

Maximum supported CPU speed is 200MHz - at best 20% improvement over 166 - it would be HARD to see the difference.

P55C means the board can support BOTH P54C and P55C CPUs.

P233MMX MAY run at 200MHz, but not 233 (no problem IF it does work) but the MMX features will not work.

Changing your BIOS would be RISKY and WOULD NOT improve your speed.

The problem your computer has is to decide what to retrieve from the DVD (CPU and DVD controller), to read the data and move it to a buffer in memory, and to move the data from the buffer to your monitor screen. This is a case where the slowest component rules.

Some things that MIGHT help:

1. Check your DVD specs - if it is capable of UDMA/33 or UDMA/66 then an ATA/66 IDE controller could speed up data transfer from DVD to memory - probably limited to about PIO-2 (now).

2. An overdrive processor could about double your CPU power - IF your board and the ODP specs match. You can get one for about $50 now at:

3. A video accelerator might help as well by using onboard memory and a video proccessor - speeds up moving from memory to the screen

4. SIMMs are available as 60ns and 70ns speeds - make sure you have 60ns memory and if you get any new SIMMs get 60ns. Expect a very small improvement, if any.

5. Expanding memory to 128MB might help a little - it could help a lot if you can assign some of it to a "permanent" cache for the DVD to use. This might help with the memory you have now.

Good Luck,
Henry
