I inherited a Sam460ex from a trade with someone. Let me start with specs. It is built in a Silverstone Case w/front USB and Audio Jack. 550 watt power supply. 2 GB of DDR2 RAM, XFX Ghost R7 250E 1 gb VRAM don't know if it's DDR or GDDR. sli3114 card DVD RW connected to Port Com1 of sli3114 and 1 TB SATA HD connected to Port Com2 of sli3114. U-Boot was updated to 2015. AOS 4.1 FE. Graphic glitches on U-Boot screen on hard resets after boot up periodically. Video Card fan in high speed with no picture after software reset and soft resets. I have DVD RW connected to com1 and set as first boot device, setting remains in U-Boot. Reports in Media Toolbox LUN 0,0. I have SATA HD connected to com2 and set as second boot device, setting in U-Boot defaults to 3x12 HD, yet Device 3 in U-Boot remains as 3114 HD. Reports in Media Toolbox LUN 2,0. I've read in this forum about this and it is a bit cloudy as to why this is.
I completed a full erase on the HD on my Mac and formatted the HD to MBR Partition Table and MS-DOS. Performed a new install of AOS 4.1 FE and Odyssey and finally got Grim Reaper out of the way. It appears this video card has very poor performance. Tried to watch a youtube video. No sound and slow motion video. RunInUAE had very poor performance the game Agony - video slow and jerky screen scrolling.
I oredered a Radeon HD 5450 and a 2 GB stick of DDR2 PC2-5300 SODIMM and a 2 GB stick of DDR2 PC2-6400 SODIMM. Awaiting delivery. Was this Sam a case of trying to make a Rolls Royce out of an Opal? I used on-board video and proved the U-Boot graphic artifacts go away. I proved I have poor video performance in RunInUAE. Here's where advice and someone's knowledge is needed. Am I on the right track?
I, of course, bought and attempted U-Boot update but this is to no avail. I would like to know all the default values for U-Boot nvgetvar. Maybe I'm overlooking something there. I hope The 5450 card and new memory may resolve some of this.
Please advise. I'll try to answer any questions anyone may have.
