Bad harddriver marks with kt266a?

I got a Abit KR7A-RAID with IBM deskstar 75GXP and 60GXP.
When i test my HDs in sandra I hardly get more marks then a UDMA66 7200rpm disk?
I got UDMA 100 IDE cables so what can I do to improve my marks?
Or can it be any settings or options that I don't know of?

I have the same board and I've read on the OCWorkbeck BBS that there appears to be a latency issue with the chipset. This may be the cause of your issues, they also had a patch available. I used it but never did a "before and after" benchmark to see if it was of any benefit. If you do could PM me the results as I'd be interested in find out if it makes a difference?

Link to Abit forum on OC Workbench :link
 
Where can I find this patch?
I'm allready using VIA 4.37a if thats what you are talking about?
I have also tryed the vlatency v019 patch but that don't help.
 
I have tryed vias latest IDE drivers to 3.14 but they don't help 🙁
I have dubble checked the udam status and it says that the disk is using udam5 that should be UDAM100.
So why do I only get marks for a UDAM66 disk?
I have the same problem with my hardrive that is on the raidcontroler.
All my drives have bin working fine on UDAM100 before on my old promise card.
So please help me if you know my problem!

This keeps coming up with IDE RAID - maybe we could get a mini-FAQ? Sandra is not a very reliable disk benchmark for some (at least) IDE RAID controllers. People with seemingly identical setups (including latency patches, 4-in-1's, etc.) can have differences of 20000+ points in Sandra's drive bench. By this point I've searched extensively all over the web on this topic, and no one has offered a satisfactory solution. It's not clear whether the problem is with the way Sandra calculates its score, some component of XP (seems to happen most there), a driver issue, a chipset problem, or even whether the performance really is any worse than it should be. And because people keep on using Sandra anyway, there's no collection of other benchmark scores to compare against. HDTach isn't much help, since the unregistered version doesn't test NTFS.

What to do? Well, ideally we'd use Iometer (available here). This bench was recognized by Storage Review as the most reliable disk bench. But Iometer takes a lot of work to configure and standardize. I suggest ATTO Pro-Tools, which you can download after free registration here. I'm going to make a post later tonight asking for ATTO benches - I'm getting tired of this uncertainty. Until then, try ATTO and compare it to my results (dual RAID 0 60GXP's on Promise onboard): max read/write peak speeds levelled off at 43k-50k after the ~64k file size. Some other ATTO benches, SCSI and IDE, are linked to here.
 
The thing is that I don't run raid.
I only use the Raid controler for a extra disc right now.
So I get bad marks with both the discs on the moderboard controler and the raid controler.

I diden't get much out of Iometer and atto is only of scsi?
Tach is only free for win98 user so I can't use that.
Got more bechmark programs that I can test?
 
Going from UDMA66 to UDMA100 isn't going to give you any kind of tangible performance gain. It will increase the speed of your burst transfers, but those do little for real world performance.
 
DOH!

Don't you think a want to have what what I'm use to and payed for to have?
My old system worked great with UDAM100 no problems.
Now with my new MB I got this problem.
 
bovinicus said it well. i found weird results from sandra on my ide raid setup as well

<< It's not clear whether the problem is with the way Sandra calculates its score, >>


2x30 gig 7200 rpm maxtors
started at 25000 on a fresh install of xp pro
installed the newest promise patch (pp1p or something like that)
installed the pci latency v19 patch
running 40000 now. i have no idea what it really means, but 40>25 🙂

i should have done tests between each patch to see where the gains were (but there may not have been gains at all, just odd stuff with sandra).

i would use hd tach, but i dont wanna pay for the pro version (49$). the regular wont work in xp 🙁
 
My dad have the same motherboard and type of discs as me and he get around 18000 marks in sandra.
I got better marks with my old promise card so I really like to know what wrong with VIAs UDAM100 controler.
But the thing is that I get the same bad marks with the disc that is on the raid contoler.
If I pay for UDAM100 contolers and have UDAM100 HDs I really like to get the performance.
Can this be a driver problem or a hardware problem?
What ever I really like to fix this.

I have dubble checked the cables and that windows is using UDAM5 that is for UDAM100.
But I still don't get any preformance!
 
Stop using freaking sandra to benchmark your hard drive. That's the problem right there. It's results are almost useless.
 


<< also try setting pci latency from 32 to 64 in the bios (read this in another thread...) >>



Where do I set this option?



<< Stop using freaking sandra to benchmark your hard drive. That's the problem right there. It's results are almost useless. >>



Then give me a program where I can test my marks!
 
no idea where to change it, saw it in another at thread somewhere...ill see if i can find it
hd tach requires 50$ to use under xp, and apparently iometer is a pain in the arse.
 
Ok I got the HD tach program to run.
Looks like the VIA controler is working fine.
But I got a bad MBPS rate on the disc at are using the highpoint controler.
Only 48 mbps.
I got 80+ on the other drives.
So whats wrong wit the highpoint controler?
 
Highpoint controllers suck I have always for higher benchmarks on the standard controller. My brother has a Epox 266A chipset motherboard and he is getting about 24000 on his benchmarks with his Seagate hard drive in Windows XP. I don't like motherboards with the built on raid controller if you need one get a motherboard without one and add a good raid controller card.
 
Well want I know of the Highpoint controler should not be that bad.
But this is buging me so do any one know anything I can do to get UDMA100 working on that disc?
I checked the settings in the HP BIOS and I says that it is using UDMA5 = UDMA100.
But WindowsXP thinks that my disc that is on the HP controler is a SCSI divice?
I'm using 2.3 HP drivers and HP BIOS version is 2.0.1024.
So is there something I can do?
 
I have updated my highpoint BIOS to 2.3 and I still get bad marks on that drive.
What I don't understand is how Abit can sell this as a UDMA133 controler when it hardly can make UDMA100 to work?
If there is something I don't know of that I can use please tell me.
