New Via in1's are worth it.

I just upgraded to Via 4in1 ver 4.45 from 4.43 and saw a 12% increase in cEMs/sec on a dual P3 Tualatin @ 1.33 Ghz.

75809 to 85117

Wow. Seems to have worked for me. 54k --> 62k cEM/s. Athlon 1.2+w2k

Then, enabling 4-way ram interleave in bios got me up to 65k.

[jjjjL]

Yeah, wow. Good find. I was a little skeptical when I saw this post and thought maybe it was a fluke. I just installed the 4-in-1 drivers on my 1.33GHz Athlon box and had an increase from 64-->70kcEMs. Very nice.

I already had the 4 way interleaving on so maybe that's why I didn't gain as much. In any case, I'd definately recommend upgrading if you have a VIA chipset.

I also got a similar increase. I'm wondering what exactly they changed to get so much performance boost.

The Intel Application Accelerator does the same thing...

I believe the *all* portion is not quite correct. On the page they're talking
about Kt400 users. I have Apollo Pro 133A, and for me the new drivers did nothing.

My windows machine is running on an MSI 6330 Lite board, based on VIA KT133. It's a low-end, DDR266 board running an Athlon TBird at 1400, but those new Via drivers did boost performance by about 15%. With that kind of gain, it's worth trying, even if it doesn't produce any gains on a particular system.

So different chipset and different CPU manufacturer from what I have. Either of two could explain why you see the improvement and I don't.

i'm using a totally different mobo and processor
MSI K7T266 Pro
MS-6380
w/ Athlon XP 1900+ @1728mhz
1gb DDR Ram
and my performance increase was about 15%

Maybe 'all' isn't 100% accurate, but it seems 95% is, so.....

It's too bad they didn't work for you - they've been quite stable and well worth it for me. Perhaps you have some BIOS settings holding you back, or perhaps you are using the Intel app referred to previously. I have no experience with this one, so I am taking the post at face value.

BTW I am using them on an MSI Pro266TD Master (Apollo Pro 266T Chipset)

Merry Christmas!

An easy overclock to try is changing the CAS setting in the bios from 3 to 2. This reduces access latency a little bit. Most memory will take it, but it may be unstable with cheap ram (expensive stuff is often rated for 2); however, I've done it on two machines with no decrease in stability, and a couple percent increase in performance. I recommend it. :)
