Hi there!
I've just bought 4 sticks of OCZ3P13332G memory to use on my system, with an Intel DX48BT2 board but, after I installed the memory, my system becomes very instable, with random reboots, especially when starting a game. Sometimes it reboots when booting the OS. I already set the memory voltage to 1.82V on BIOS, and even tried to reinstall the OS (Vista x64), but, no success. :bonk:
Before I bought these memory, I was using an Fatal1ty 4GB dual channel kit (OCZ3F13334GK) with no problems on my system. The only things I had to set was the memory speed to 1333MHz (the BIOS auto-recognized it at 1066MHz) and the voltage to 1.7V. I'm using this kit now, as I already said, sometimes I can't enter Windows without a reboot using 8GB!
Is my board incompatible with 8GB memory? Or there is any special config to run it stable?
Thanks! :thumbs:

Set a few more timings for me. tRFC 88, tRC 40, CMD 2t. Raise your chipset voltage to 1.4V and test things again. If its still unstable with 4 sticks test the pairs on their own

Hi, sorry for the delay to answer, I was in a trip in the last days.
I made a lot of tests here, tried to raise the chipset voltage as suggested, and changed the other memory parameters too. With these settings, the system booted ok, but, afther some hours of gaming, I got a blue screen.
I tried to test the modules in pairs (4GB of system memory) and, the two pairs worked perfectly. The problem comes only when putting all modules together (8GB).
Well, besides that, the good part is that I noticed some improvement of these Platinum memory over the Fatal1ty series on the Everest memory benchmark, especially on read/write and latency. I'll keeping my system running with 4GB until find an solution. Thanks!
