Sam440ep Setup Tool and Update 3

Hi,

ACube said in their news item for the Sam440ep Setup Tool that this utility will be obsolete with a future AmigaOS 4.x update.

So is this the case now with Update 3?


Thanks

This is about to fall off the first page, so here's a bump. I'm interested in the answer to this too.

I am very interested to hear too.

However, I run some benchmarks (Q2/Q3 timedemos) and I get nearly the same performance that I had with U2+Acube's patches on a clean installation of U3 without previous ACube's patches.

Sam440EP_Setup is still required:

53.AmigaOS:> AmigaOS:System/sam440ep_setup/Sam440ep_setup VERBOSE

Done !

Thanks Chris for clarifying.

I tried it on my Sam440 and the result is the same. So with AmigaOS 4.1 Update 3 the Sam440ep Setup Tool is still required.

on a similar note, is noone going to do any kernal,OS,mem, gfx, drive, game regression / speed tests ?

@angelheart
Are you offering?

I have problems with Sam440ep setup utility after update3.
It appears to be running fine, but for unknown reasons my GL screenblankers we stuttering and running only at 1 or two fps. I also don't get the 63MB/write speed on the videobus anymore......

Posted this on Hyperion forum but I believe these findings might be helpful here as well.

Due to other problems I ended up trying the entire 4.1 Update1 kickstart with Update3 (basically only the latest MUI, theme and few other things stay the same) and the findings are quite surprising:

RageMem Values with Vanilla Update 3:

CPU: AMCC PPC440EP 1.3 @ 799 Mhz
Caches Sizes: L1: 32 KB - L2: none - L3: none
Cache Line: 32

MAX MIPS: 1598

WRITE64: 199 MB/Sec

---> VIDEO BUS <---
READ: 15 MB/Sec
WRITE: 58 MB/Sec

By adding the Sam440Set_UP in the start-up, the only improvement I get is that the VideoBus "READ" is raised to "39".

Below instead, you will find the results of the RageMem test using Update 3 but with the whole Update1 Kickstart swapped in + Sam440_SetUp (more Update1 than update3 in practice):

I wonder why with the newer Kickstart the Sam440_Set up file doesn't improve the sistuation as strongly as it does with the older kickstart.

The fact that it's still needed should be made more clear to everybody. Anything that helps in terms of speed is more than welcome.

Yup, and another thing that should be made more clear to everybody should be "WHY" such a file doesn't produce the good results it used to provide... (very curious about this...)
