Mainboard M810LR and SDRAM timing of 222?

[onTheBus]

Dear forum,

My mother has an old PC with the following board and CPU:

CPU 01 : AMD Duron, 797 MHz (800,00 MHz = 8,0 x 100,00 MHz)
CPU 01: Kernel/Socket : Spitfire / Socket A (462 Pin PGA)
------------------------------------------------------------------------------------------------------------
Mainboard : unknown
BIOS Type : AMI-Hiflex v6.27.10
BIOS Version/Date : 062710 / 07/15/97
BIOS ID : 62-0914-001437-00101111-071595-SIS730S
------------------------------------------------------------------------------------------------------------
Chipset : SiS 730
Model: M810LR

For this board I wanted to buy her 2 new 512MB PC133 133MHZ SDRAMs (supported according to the manual) with a timing of 222. I asked me whether this chipset/CPU combination supports these timing-parameters since in the mainboard's manual there was no information concerning this.

Another question I have is whether a newer processor of the K7 architecture, e.g. the Athlon XP 3200+ would run with this board without too much performance degradation (considering the 133 Mhz FSB)? If so, which processor could you recommend to work best/fastest with this board? Would a BIOS-update be necessary?

Many thanks in advance for any help.

Looks like a pcchips motherboard. Inspect your old ram and use cpu-z, a free download to see what specs it shows for the ram. Hard to say if the new ram will work; it's so old.

Yes, thank you for the hint . I already used cpu-z. Currently, there's one 256MB PC133 module (Infineon) with 333 timing in use. I have read somewhere, that there are downwards compatible modules who support both, 222 and 333. Maybe the best choice.

You should determine the max size ram module (per slot) before ordering by locating the specs on pcchips website. It could be only 256 mb. If it is, the new 512 sticks may not even post.

 

[onTheBus]

yes, good point. But I checked this in the manual. It's 512 MB per slot and they explicitly state that the maximum sum therefore is 1 GB. But what they did not state is whether I need single or double sides (DS) DIMMS. From the outside they looked like DS, but the internal organisation can be SS as I learned.
