Recently, after a hard drive failure, I replaced my old boot drive, and IDE 60GB HD with an IDE 120GB HD, and as well, replaced two older generation 1 SATA (500GB and 350 GB) drives with 2 2TB SATA drives in Raid 1 (Hardware). This machines uses an older A7N8X motherboard with 100 MHz Ram (2 GB) and an AMD 1800+ CPU. The SATA Drives are fed from a silicon images 3124 card. The machine is using OpenSuSe 11.2 32 bit.
One partion of the 120GB drive is NTFS, the other is extended with swap, boot, /. The 2 TB Raid is /home.
No matter whether I used hardware raid or software raid, whenever I do any kind of activity that uses the hard drive a lot I get crashes that lock the machine up completely. Programs stop running, the mouse freezes, etc.
The only way to restart the machine is to turn off the power. It starts normally after it fixes the hard drive partitions.
My guess is that the motherboard is so old and slow it’s not able to keep up with SATA 3 hard drives. I don’t know whether upgrading the memory to PC 3200 (400MHz) and or the CPU - I can go up to an AMD 2800+ is likely to fix the problem or not.
Can some of you suggest whether I should just replace the mobo or the memory and cpu. My dilemma is that money is important, and I don’t want to replace the cpu and memory and then have to buy a new cpu, mobo AND memory.
Alternatively, is there something else I should check first?
I used to have one of these with an AMD 2200+ as I remember, but this was a long time ago. I am thinking you kind of blew it away with those (2) 2 Terabyte hard drives, worth a lot more than that motherboard/CPU combo. It is kind of like attaching a couple of missile launchers to a Dinosaur. I never want to suggest to someone they should consider replacing a motherboard that works, but really, it is time to spend some money on the main foundation of your system. I would look at some Intel i7 LGA 1156 motherboards/CPU combos. You need to only add the DDR3 memory two sticks at a time and not three as the LGA 1136 line needs. These are getting cheaper since they are moving away from that format and the speed is beyond anything you have seen with that old 1800+. It is just a suggestion, but do consider it and good luck.
It might be worth, before replacing the CPU, to do some basic maintenance, if you haven’t already. A good (but delicate) dust up, remove and re-seat the expansion cards (check RAID card connector, clean with an eraser pencil if needed) and memory. Run memtest from oS install DVD for a few hours at least.
