I am wondering if anyone has some input on this. I have an ASUS A7V600 that started randomly locking up. My initial suspect was the RAM,. It has two Kingston value ram 512 modules - they are the same part number but one has Mitsubishi chips and one has Nanya chips.
I figured one was going bad - so I pulled out first one and then the other. With either chip alone, it runs fine. I put them both in, it starts locking up again.
I could understand the chips not working together - but the system worked fine for a a good two years in this configuration. Why has this now become a problem? Has something on the motherboard gone bad? I tried changing the CAS latencies in the BIOS - setting it up to 3 the system would not work at all - 2 or 2.5 same problem.
I was thinking of ordering some new RAM from Crucial - at least they would be be matched - and see if that fixes the problem. I should add that I believe these were used when I got them (they were advertised as "pulls") so I really do not know how they were used in the past.
