OCZ Memory Troubles, Advice Needed

Ok, so about 3 weeks ago I got another 2gb dual channel kit from ocz (had the same kit already, decided to double my memory) and ever since I got that installed I have had nothing but trouble! BSOD like all the time. So I started doing some experimenting, and concluded that one specific stick was causing the problems. The system will work just fine if I pull that stick, but will BSOD within a few seconds of booting with ONLY that stick installed. I have contacted OCZ about it, and they say that I need to set the ram to run at 800mhz, and change the timings. However, the ram is set up to the specifications that OCZ suggests on their website. Is there something I dont know about running 4 sticks of ram? Thanks!

Here's the ram.

Run memtest on each DIMM. Be sure to adjust the voltage as well as timings and speed to specs in BIOS. If one module shows errors, return the entire kit. OCZ special.

Yeah, sounds like you have worked with it and know something is wrong with it. I would tell OCZ support the RAM appears to be bad at least in your machine and ask for an RMA replacement. OCZ has sent me 'dead' RAM as a replacement!

allrighty.. Finally convinced the RMA guy to send me some new ram.

Just for future reference, do I actually need to underclock my RAM to run all four sticks together? I have never heard of this in my life, until talking with this RMA guy. he was telling me to drop it down to 800mhz, and make the timing 6-6-6-20

The ram I paid for is supposed to run at 1066mhz and with 5-5-5-15!

Motherboard: ECS nforce9m-a
Processor: AMD Athlon x2 7750, @ 3.2ghz
PSU: Antec Earthwatts 430w
GPU: ATI Radeon 4830 512mb

Thank you very much for all your help Badge! I am very aware of how cheap the motherboard I have is, its pretty much the most basic thing you can buy. I am thinking that probably has something to do with the voltage regulators and stuff you were talking about. Even so, I know it will run 3 sticks at advertised speed just fine, as I was doing that for the past week. But that is actually good in my situation since I am on a 32 bit OS and could only really use 230mb of that 4th stick anyway!

Sorry, you have 4 x 1GB. I use the G. Skill I linked in a micro with no voltage adjustmet at all. 4 DIMMs eight GBs for my system. Runs super.

Remember, it will take more voltage to power 4 DIMMS than three. That OCZ you have requires a minimum of 2.1v to run at 1066MHz. It is possible your micro MB can not supply enough juice to four DIMMs. And, the PC26400 I linked requires 1.8v, which is what the BIOS default voltage is. And that G. Skill will run 'near' PC28500 1066 with voltage increase.
