I have a Asus M3A32-MVP DELUXE motherboard and I have had some memory problems in the past. After a memory check I removed the faulty stick wich was at slot 1(I took the pair, not just the one faulty stick), and replaced them with new ones. In the start I had 4 sticks coupled two and two in dual channel from the same vendor with the same specs. The vendor was Geil.The memory is 1066MHz PC8500. The motherboard was advertised to run PC8500(random site here:
http://www.afterdawn.com/hardware/product_details.cfm/6773/asus_m3a32-mvp_deluxe_wifi-ap), but I actually have to "overclock" to do that. So I did, and have been doing for the last year.
After removing two of the sticks I couldn't find sticks from the same vendor with the same specs, so I bought sticks from another vendor(Patriot) with the same specs. In the process I noticed a list with approved memory manufacturers(you can find it at:
http://support.asus.com/ search for M3A32-MVP DELUXE). The vendors I was bying memory from were not on that list.
Before installing the new sticks I tested memory again with the faulty sticks removed. This time I got no errors. Now I installed the new memory and again tested for errors. I note here that slot 1 held errors earlier, but that stick was removed. Now when i test both slot 0 and 1 show errors. Slot 0 was healthy before I installed the new memory and slot 1 has a new memory stick that should be OK. To make things clear: Slot0: Geil, Slot1: Patriot, Slot2: Geil, Slot3: Patriot. Patriot is the new memory and Geil is the first functioning older memory. They all have 5-5-5-15.
The memory sticks from Patriot come with cooling ribs, but the Geil sticks have no extra cooling.
I am kind of frustrated. Where are the memory problems coming from? Bad luck, me or a faulty motherboard? I noticed that the memory test runs at much lower speeds then the memory(DDR1, the memory is DDR2).
