Fast-ATA MKIII for A1200 issues - Page 4

Do you say CPU/FPU MIPS? That's what I first searched, but it seems it doesn' affect to them. I've got 18.80 MIPS that is (for what I remember) what I was getting before installing it. That's not much, but I think (I'm a newbie, remember) it only deppends on the accelerator.

EDIT: Well, I was getting 105,70 Mips with a B1260...

Hiya,

It's actually hard to see what the CPU load is (unless there is a utility on AmiNet?) because the load will only occur when your actually reading/copying a file.

You might be able to simulate it by:

1) Run SysInfo and make a note of your MIPS (run it 3 times to get an take the average).
2) Leave SysInfo running and then coping a very large file from one partition to another
3) When the system is copying the file, switch back to SysInfo and check the MIPS again.

Hang on, are you saying that SysInfo is reporting 18.80 MIPS for your ACA? That's huge

Retrofan · 11 March 2011, 00:26

I've measured it three times with SysInfo. It gives less than SysSpeed:
12.04, 12.03, 12.04 Mips. I've started a copy of System in Dh1, and repeated the test: 11,69, 11,69, 11,68 Mips.

EDIT: Huge 18.80? If I was working with 105...

NovaCoder · 11 March 2011, 00:35

Ok put it another way: 18.8 out of your 030 == very good, 18.8 out of your 060 == very bad

Anyway, looks like there is a very small cpu load going by your results (<5%).

Retrofan · 11 March 2011, 00:39

Surely you're right... and I haven't the ACA overclocked still...

EDIT: Hey, wasn't there a guy that overclocked it? I don't remember who was... and what happened...

rkauer · 11 March 2011, 03:16

Not on here, although at least Fitzsteve & Davideo are members here.

They, plus Cosmos overclocked the ACA630 to lovely 60MHz, IIRC. Check on Amibay.

NovaCoder · 11 March 2011, 03:36

Got a linky?

Cosmos · 11 March 2011, 05:26

@rkauer

Only 40 Mhz !

At 50 Mhz, the ACA630 give me a yellow screen at pwr on !

It's 2,9%

Perhaps Thomas could tell which would be a good number of buffers using PFS3 for DH0 (<1Gb), DH1 (3Gb) and Dh2 (12Gb), and if they (and how) affect to the speed you can get.

thomas · 11 March 2011, 17:29

I cannot say more than is written in the docs. I don't have the guide here but IIRC it says that 600 is the maximum number PFS3 can deal with and that block size should be set to 512.

Generally more buffers reduce seek times. Sequential accesses are not affected.

Furthermore, if it has enough buffers for what it needs to do, then more buffers do not increase speed.

Each buffer needs 0.5 KB of RAM.

So you should decide how much RAM you can afford to be reserved for HDD buffers which are not used most of the time anyway.

If you do big copy operations of many small files, you can add buffers by the Addbuffers command at any time.

Retrofan · 14 March 2011, 23:08

Ok. Buffers at 250 in Dh0 and 600 in the rest. Now I've got 9,540,000 Mb/s in DH0. Won't try with more buffers, I think that's enough.

I want to tell too that in the BPPC instructions it says that with the SCSI you can get a maximum of 10mb/s, so I believe that although the ACARD can get more speed, you can't because of that. So, I think 9,830,040 must be very near the max. any can get with an ACARD. It possibly can be improved with a Fast Ata, as for what I remember it says you can get till 16mb/s.

It's very extrange what's happening to me with the CF HD's. I did a copy of the one which I'm usually using and it doesn't boot, but I have the same problem with another three Cf. Now there's only one that boots and runs in the ACA Amiga with the Fast Ata.
Today I taked a new one, Trascend 133x, 16Mb. I installed OS3.1 and it was booting right. I installed the same instructions I've got in others for ACATune and Fast Ata in second place and selected Pio 5. It seems it was to much for the Trascend, as it wasn't booting, but the thing is that even disabling all those instructions it doesn't boot anymore.
Well, at least I've got a Cf HD that runs with those 9,54Mb... what more can I ask?
Will try anyway to install a complete OS3.9 boingbagged 4 and then will try the ACATune and later the Fast ATa.
