Awesome results with new 1.2 TBird just built today......

[steepcurve]

I just put together a 1.2gig Tbird based on input from members of these forums. Here's a quick summary of my early results:

System:
Abit KT7A
Tbird 1.2gig
Crucial 2x128meg cas-2 ram
Plextor 12/10/32
IBM 45gig 7200rpm udma100
SBLive
Hercules Prophet II mx (with the hyundai memory)
Tornado 1000 case
Alpha PAL6035 with Arcitc silver (paper thin) and a 26cfm fan

Results:

T-Bird is stable at 1461mhz (10.5x133+6)
Temp (as I write this - 34 celsius)
SiSoft numbers:

CPU: 4095/2002
Memory: 581/636
Multi-media: 8174/9926
Hard Drive: 12565

I believe this is all great except the hard drive. Any Ideas on what to do to improve that performance? I do have DMA checked off on the appropriate space, but my scores are only just on line with UDMA 66. Shouldn't my results be higher?

Thanks for all the tips and recommendations - this system is GREAT!

that is an awsom OC will it go any higher the memory score`s seem a little low put up a pic of your sandra score`s ;D

Very nice for an air cooled system indeed. My pep 66t had my 800 pushing 1.2. Switched to water cooling got a little more, broke the clip on the board: back to my old p3 400 till i get the replacement parts
yes cpt kirk you can push it too hard lol

I think the limiting factor is the T-Bird. I tried all sorts of combinations, but a couldn't even get 1470 to run stable in windows, and 1481 wouldn't even post. I suppose the memory could be made faster if I lowered my multiplier to 10 and increased the fsb. I tried that though, and had SBLive problems. I still think the hard drive is not optimized though.

Holy smoke, that's pretty peppy!

turn off the acoustic management on your drive. that'll give you a bit of a jump. go to ibm's website and dowload the tool to do this.

[steepcurve]

Good idea, but I already tried that.....
What's really annoying is that I have a couple of western digital udma66's (30gig) on a DFI mobo and they score slightly HIGHER than this IBM drive.

Hmmmm.....

seem`s that iread somwere that wd and ibm use the same comp`s like chevy and gmc correct me if im wrong

Have you checked to see if the DMA block is selected for the drive in Device Mangler??

[steepcurve]

Yep, I did that too. I think I did all of the obvious stuff. Regarding the WD drive, even if WD & IBM use the same hardware, my WD is DMA66 5400 rpm, and the IBM is DMA100 7200 rpm. Should the larger drive be slightly slower?
The only other thing I thought about is the eide cable. On my WD system the eide cable has a cut in one of the cables. The cable attaching the IBM drive does not have the corresponding wire cut. What if the function of the cut wire?

Thanks again for all of the suggestions.

What OS are you using? In Win 2k, I had to tell it to run the drive in UDMA mode. It defaulted to PIA, which is quite slow.

[something clever]

you're using the 80 wire IDE ribbon, right?

[steepcurve]

I'm running both WinME and Win2000 (dual boot). My test results are under Win ME. The cable i'm using is the 80 pin cable. Is there another one that will fit? Thanks for the ideas though. I'll just keep trying......

I have an A7V, with a Seagate 20GB 7200 RPM UDMA 100 drive and get the same results as you. I have tried the DMA100 slots as Primary, secondary, on it's own, with 80 conductor cable, and one with the cut in one wire making it 79 conductors. Tried it as above in the normal IDE slots with all of the above and still get same results, but slightly higher than the DMA 100 ports, can't work that out? I have Win ME, tried it with Win98SE, all latest drivers etc and gave up in the end, just wasn't getting faster. I know that the DMA drives only transfer at 66MB/s but can go up to 100MB/s in burst mode, but the 7200RPM shold give them the edge. Maybe it's just the Sandra benchmark utilitie, any one else got an idea?

UI had really slow harddrives benches on my KT7-RAID, so I flashed the latest beta bios and latest highpoint drivers and they doubled!

But if yo uare using the onboard via IDE - do you have the latest 4 in 1 drivers?
