Overclocking Xeon 5450
Please help me understand what is going on. I been using Hynix DDR2 667Mhz RAM, (5-5-5-15) which allowed me to get to 3.8Ghz on the CPU. At this setting the RAM runs at 890MHz.
This seems to be the red line here, because if I go any higher, either the system wont boot or it boots and there's BSODs, errors, etc.
I am pretty sure that RAM is the limiting factor here, because the CPU temps are fine, and plenty of people got their X5450's to 4.0GHz and beyond. Therefore I bought some more expensive RAM on ebay.
It's OCZ Platinum Edition 1066MHz (5-5-5-18). I popped it in and thought I would easily get to 4.0GHz now, but guess what... I cant even break 3.0GHz !!! Anything higher, and the system wont boot! To get the CPU to even the same 3.8GHz, the RAM overclocks way above 1066 MHz...
Why is this, when the Hynix RAM could do it at 890MHz which was much less? What am I doing wrong?
