Lockup playing AVI file with pivoted display

wrote: Russ, what is your need in pivoting your display on this admitted antique? You have so many variables here...old architecture being one of them. I am writing a program for a Field Programmable Gate Array (FPGA), and I do some of the work at home. It is a larger design than what I have done previously and has taken much longer than I expected. I felt a desire for more pixels at work because the schematic and text portions of the design are large. So I comandeered an unused 1600x1200 display (Dell 2007FP) there. I liked it so much that I bought a used one for home. I use the pivot mode most of the time because it is better for editing the schematic diagrams and especially the text files. I also like pivoted mode better for most other purposes. Playing an AVI file in pivot mode at home is definitely optional. It just keeps me from having to un-pivot (is that a word?) the monitor back to normal for playing an AVI file. The new CPU is also related to some of this. My computer at work is about 2.5X as fast as the one at home. I was also using an MS-DOS program for simulating mathematical aspects of the design. I found having both the MS-DOS and FPGA compiler (Altera Quartus II) in memory doubled the already-long compile time at home. Compile times at home were getting onerous. I considered replacing the computer at home with a new one with Intel 2600 or 2600K CPU until Intel found a significant bug in the chipset. Motherboards and systems were withdrawn and Intel estimated $700 million to fix the bug. AFAIK it still hasn't been fixed. I thought a CPU with hyper-threading would stop doubling the compile time because my computer at work, which has a dual-core CPU, did not exhibit this. I thought a faster CPU would also help me to play 720p MKV files. So I bought and installed a used 3.06GHz CPU, the only Northwood CPU with hyper-threading. It reduced compile time slightly without the MS-DOS program in memory, stopped doubling the compile time when the MS-DOS program was also in memory, and sucessfully plays 720p MKV files too. One more experiment: I played a two-hour AVI file from an internal IDE hard drive using VLC with the monitor pivoted. There was no lockup. So the IRQ shared by the video board and eSATA controller board might be related to the lockup when I play AVI files from the external eSATA drive. Russ |

I can't speak for i7 desktops, but a Lenovo Thinkpad T410 with an Intel i7 I sold to a client recently is downright awesome for quad-core computing power AND for low electrical power consumption...

Ben Myers Thanks for the information. I see that Intel introduced the Z68 chipset yesterday (May 11). I might get a new motherboard or computer with the Z68 chipset later this year. Russ |
