Re: Sam440ep Setup Tool and Update 3

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

---> CPU <---
MAX MIPS: 1598

---> L1 <---

WRITE32: 2877 MB/Sec
WRITE64: 5685 MB/Sec

---> RAM <---
READ32: 316 MB/Sec
READ64: 316 MB/Sec
WRITE32: 199 MB/Sec
WRITE64: 199 MB/Sec
WRITE: 873 MB/Sec (Tricky)

---> 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):

RAGEMEM v0.37 - compiled 11/06/2010

CPU: AMCC PPC440EP 1.3 @ 799 Mhz

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.
