KT3 : Boost your ATA133 IDE Burst Rate Performance!!

Hi everyone.

I've lost the first copy of this guide. This is a total rewrite and I hope I didn't leave out anything I wrote before.

There are many issues with weak IDE performance on KT3 Ultra board, in fact with most VIA chipset based boards too. This could probably due to the VIA PCI timing control that impacts the IDE performance. There are some PCI patches like VIA RAID Performance Patch and George Breese's PCI Latency Patch to tackle this problem. This guide will focus on how to install these patches accordingly to get true ATA133 performance on your system.

Here are some preparation you need before anything.

Requirement:
Here is the step-by-step guide:
  1. run HDSPEED.EXE to get the hdd benchmark result. If it's well below 80MB for bandwidth, your system need to be tweaked.
  2. Install VIA 4-in-1 driver. Installation guide is here from viaarena.com
  3. Restart PC.
  4. run HDSPEED.EXE to check any improvement. If still below 80MB, your system still need to be tweaked.
  5. If you have RAID drives on your system, unzip the RAID Performance Patch and run SETUP to install the patch. After installation finished, Restart PC. Of course even if you don't have any RAID arrays , you may install VIA RAID Performance Patch too, it won't affect the system.
  6. Run HDSPEED.EXE again to check any improvement, especially if you're running RAID.
  7. Unzip the PCI Latency Patch to a temporary folder, run SETUP.BAT. After the patch installation completed, restart PC.
  8. run HDSPEED.EXE again. You should be able to get 80MB/40MB now! :)
There are some assumptions I need to mention, here are them:
  • This guide is based on Windows XP, I assume it works for Win2k and Win9x too.
  • This guide works for both RAID and non-RAID system.
  • The result of HDSPEED for tweaked system is Bandwidth over 80MB, Sequential over 40MB for fast ATA100/133 harddisks, ie Maxtor D740x 95MB/42MB. If anything lower than 80MB/40MB, your system need to be tweaked.
  • Ultimately it is George Breese's PCI Latency Patch 0.19d that boosts the burst rate. Anyhow I do recommend to install both the VIA 4-in-1 drivers and VIA RAID Performance Patch to cover some patches that PCI Latency Patch doesn't cover. The installation sequence must be first VIA 4-in-1, then VIA RPP patch, then lastly PCI Latency Patch.
  • There are some other performance patches other than PCI latency patch done by George Breese's patch. So overall, it improves system performance. However, this might bring some stability issues to some system.
  • This guide ONLY improve the burst rate. It does not improve much in overall hdd benchmark obtained by PCMark2002 or Sisoft SANDRA.
This does improve my Maxtor drive from 70MB/42MB to 95MB/42MB!
Please tell us your result after attempting this guide. Please let us know if you face any issues in attempting this guide. I'll be ready to amend anything here.

Thanks for reading.

p/s: I hope I really didn't miss out anything ;)

for going through the trouble of retyping the old guide. This is very valuable information.

Can you make these posts "sticky", or is that a privilege of our moderators?

regards,

Hans

  • In WIN-98SE, I have never found it necessary to install any drivers or patches other than the standard VIA 4-in-1 pack to get 90 MB/sec burst out of the better IDE drives. That is on the regular IDE channels and drives being used in RAID 1. I cannot comment on RAID 0.

I only had to install the latency patch coz the rest was already installed and i saw improvement.
Right now the RAID is doing 81 Mb/62 Mb I also saw improvement on another bench ATTO for the first time the reading went over 86 Mb !!!!

Thanks

With a clean install of winxp with no patches:
80/60


After installing the Via 4-1 drivers (4.40) and the RPP 1.05, no latency patch:
93/81

Before installing USB 2.0 update my burst rate is 100 but lowers permanently to 74 after install regardless of MSI 2.0 patch or nicrosoft update.
If removed or disabled my burst rate returns.
I have not noticed any lowered preformance with the USB patch installed.
I was running with it disabled to keep the 100 burst rate but since installed it and have sent in support request to Maxtor on this issue but they have no fix.
I have both latency patches installed but no return to 100 burst rate till I disable the NEC PCI to USB Enhanced Host Controller B1,
It took me 4 loads of Win XP to trace it down.
Oh well, burst rate is only minor issue. It is not a permanent hard drive preformance issue.

I am having conflicts with Archtek/Smarltlink CNR Modem riser(I think). System automatically reboots when modem is activated-all other apps utilizing the PCI boards working fine. When I activate teh dial up - the system immedialy resets. I removed the patch until I find the problem. When patches are installed I had significally better results then below up to 110/50 yet when looking at the results from HDExpert the minimum data reads and min. data writes suffered significaly but the max rate was got good improvements.


I have 4 identical Maxtor 60GB Ultr/133 7200 drives - here's the results from George's Disk Performance Test

-------------------no patches----------------------------------
-----George's Disk Performance Test v0.14 --------------
---------------Bandwidth/Sequential--------------------------
Buffer Size-----Disk 1-----------Disk 2---------------Disk 3
Size ----------(C-IDE 1M) -----(D-IDE 1S)-------------RAID 0

65536---------70.7/41.8-------71.9/42.0----------65.5/45.9
131072-------76.6/41.4 -------77.6/41.5 ---------69.6/47.1
262144 ------78.6/41.1 -------78.8/41.7 ---------72.0/51.3
524288 ------80.3/39.8 --------81.7/41.4 --------73.0/50.2
1048576 -----30.0/41.0 -------32.8/41.0 --------73.6/54.9
2097152 -----39.3/39.7 -------38.6/39.7 --------60.0/63.6

As you can see the difference is when the buffer size is increased. This is with the standard BIOS load - no overclocking

Hi maesus,

if via 4-in-1 v.4.40 has stability issue, then how about v4.42.



has anyone tried??? care to post the result.

Thank you all for that infor on the IDE raid patches and more went from 60/35 all the way to 100/40@65536 115/42@ 131072 non-Raid thats what ive been looking for like forever. i couldnt ask for more thanx again :] thats with the 4.42s i'll learn how to post sooner or later :p

I did all of the steps above and no performance increases for me. I started with a 61/42 and ended with a 61/42. I went to the forum he (George Breese), recommends and saw a comment....

"(This latency patch will not work with the newer chipsets, e.g. KT266 and KT333 due to the fact that they are not on the PCI bus." They can't be used if they are plugged into the standard IDE port however, the Promise controller is.....so are all of you plugging your drives into the raid connectors, even if you are not using Raid, 0 or 1?

its about the raid ide

read maesus's article re using it as normal ide in this section or this thread at amdlink

Found that VIA changed the wording on the patch. It can not be used on the KT3 AND KT4 boards that have the VT8235 chip.

I got the impression that she wrote about raid and non-raid solutions from her opening post. Should I move the cables from the primaryIDE ports and move them to the RAID IDE ports. If I could go from 60/42 to 115/60, it seems that it would be worth the trouble.

I tried that link and DL that biosmod v5.4 and it really works :)) Just had a little trouble with the ata133 driver pac is all. installing these drivers on a fresh system would have been easier ? Didnt try that. But ya i hooked up my cdrom and writter to the Raid ide and they worked. thanx Wonkanoby
