It runs normally under win98, better than K6-2-400 on TX97.

However, when use such computer under windows xp,
The computer runs rather slow,
CPU precess always reach 100%,

the SiSoft examples show a similar speed (72/73) for that chipset at 66MHz @ CL2

aida32

RAM write 24MB
lowest in the list,


The Sis 530 mobo are Asus P5S-VM in HP Pavillian, Gigabyte 5SMM, etc.
All have this slow problem under windows xp,
even when I run setk6, condition go even worse,
oc the K6-2-500 to K6-2-550 only got better CPU marks, no better on memory marks

Who can help me to tweak the configuration under XP.
I use two 64 kingston PC100 RAM under XP,
When read these article about L2 cache problem (Sis530 512cache can cache 64MB ram only)
I take out one 64 RAM, computer is still rather slow.

all the reviews showed that Sis 530 is better than TX97, as a super7 chipset,
But my experience only show performance on XP of Sis 530 is much worse than TX97,

don't know if bios need to be furtherly configured,
anyone have simillar problem?

You have some problems :
1) Shared-memory VGA eating up parts of your memory and slowing memory transfer rate down.
2) L2-Cache problem - maybe it's a problem or your board is able to cache 128MB. Uncahced RAM is still way faster than swapping on HDD. Info from Asus: 512KB L2 = 64MB, 1MB L2 = 128MB
3) XP - needs lots of memory and with all the funny stuff enabled eats 3D-power from your slow OnBoard VGA.

First - disable all funny stuff in display options otherwise it uses a lot of 3D-functions slowing down your computer

Do a full system scan - use a recent antivirus program as well as Spybot Search and Destroy and Ad-Aware SE.

Thanks a lot for your guide,
Your analysis is very accurate,
problem lies on the on board graphic.
the problem solved last time by reduce video performance.
I reduce the share memory size from maximum 8mb down to 4mb,
adjust color depth from 32bit to 16bit,
then everything ok, runs smoothly under windows xp,
thank you

Did you run the CTCM test from a DOS Boot Disk?

Can you post the CPU MSR registers?

Thanks.

Oh, I have solved that problem long ago, just review the past post and share my results. that pc not available now.
although some review or advertise about the performance of chipset for K6-2,showed that ALi V>VIA MVP3>Sis 530>Intel 430TX/HX.
However, my test results is like that Ali V at 100MHz=Intel 430TX/HX oc at 83MHz>VIA MVP3 at 100MHz>Sis 530 at 100MHz.
So I abandaned all my Sis familly, 530,5591,5597/5598,
only left a pcchips 5591,it use AGP slot, without built in video,
so it doesn't have the above share video problem I had met on 5597/5598 and 530.
Do you still need the test results for this pcchips 5591?
Btw, my previous CTCM test all be down at MS-DOS 7.0 with option 5 "command prompt only"

the SIS and VIA chipsets aren't that bad..they indeed suffer by some really ugly bios programming crippeling some of their most important capabilities. there were some Asus boards that featured SIS chipsets combined with a very well programmed bios that unleashed the real performance of those chipsets. the same can be said for FIC mainboards that used VIA chipsets..anyway the performance always dropped significantly if any onboard vga stuff was enabled. but vgas were expensive back then and performance with those onboard vgas was sufficient with the operating systems back then. just take a look at today's mainboard market: there are many integrated chipsets which don't look too bad with today's operating systems. if, in 10 years, you would want to install the recent Microsoft Windows version on them you would say the same about them as you said about the integrated chipsets from 10 years before.

if you want a responsive system you should install linux with a lightweight window manager and look for small applications.

i did a few tests on different socket 7 chipsets myself. the intel chipsets are not bad but looking back they were overrated by the press. the intel VX chipset is a practical joke and the cacheability of the intel TX chipset is a giant step backwards compared to the intel HX.
a word on the ALi Aladdin V chipset: they had massive problems with overtalk on the AGP port lines thus limiting the speed to 1x. early revisions of the northbridge shipped with non-functional internal cache tag rams.

cp, I am trying to use and/or install AV (McAfee & Kaspersky) on a K6-2 333 256 MB w/ on board ATI Rage Pro 2x. It's fast without any AV, but very slow with Mcafee. When scanning with McAfee or installing KIS 7.0.0.125, it restarts the computer. memtest86+ 1.70 is clean so it's not memory. Linux is not an option although I understand why it is recommended. Any ideas, such as K6-2 opcode being called that forces CPU to restart? Thanks in advance.

Do an online scan first maybe at trendmicro.

Last time I saw a system restart when installing AV it was infected with some pretty nasty stuff.

Do not assume anything

I just completed the scan as you recommended, it found one cookie. I have reinstalled XP 5 times from scratch after reformatting the drive each time, same results each time. I am wondering if there is an opcode for the processor that is 'bad', or if there is another problem I don't suspect?

I have a feeling I'm in the wrong place. Could someone please refer me to a better place to ask for help? Thanks.

opcode? there is no opcode quirk for the K6-2 and windows xp that i know of.

is the cpu cooler properly installed? is the cpu voltage set to 2.2V? is the fsb not overclocked? after installing windows xp did you: install the chipset drivers (agp/ide/pci steering)? did you already try cpuburn?
If you email me include [WIMSBIOS] in the subject.
