i'm not sure if the appearance of your BIOS is different to mine but it should be similar. try Genie BIOS Settings>Memory (should be the top option)>Command Rate. if you want to combine the timings set them to the looser timings, i.e. 2-3-2-5. it sounds like you may have OCZ's EL series which would use either CH-5 or BH-5 chips on it, if that's the case the things love voltage. the Patriot memory probably defaults the memory voltage to 2.6v while the CH-5/BH-5 would probably be wanting 2.8v at stock speeds. it's risky but if that's what is happening overvolting to 2.8v vdimm may fix it. WARNING: i'm not held responsible for any damage that may occur. it should probably be ok but you must understand there is risk involved and the memory could be damaged. overvolting could end up being the only solution if that is an EL series set of OCZ because those chips basically don't like having their timings "loosened". i have actually witnessed looser timings making the memory unstable. 2-2-2-5 is what they run best but give 2-3-2-5 a try any way as it's the best option. just go into BIOS with only the OCZ in and find the memory latency/timings settings. change the TRCD value to 3. reboot, turn the pc off and install the Patriot memory, of course remembering to turn the mains power off to the pc because of the standby voltage to memory (can damage memory/motherboard installing or uninstalling memory while the standby voltage is there).
edit: lol seems like you guys continued talking behind my back while i was typing
. i might not be able to respond any further for a while because i'm about to leave for school and they finally blocked TF in my last week of school....EVER
