Hello
Before I start, let me give you my system specs:
E8400 @3.420Ghz (380X9)
Gigabyte X48-DQ6
Said RAM
Windows 7 64bit
Now, to the problem:
I've had the 4GB Black PI 1066Mhz memory set for quite a while now, but as I upgraded my CPU and motherboard I went on and overclocked my system a bit (without changing voltages). As I ran tests I suddenly noticed my RAM was listed as PC2-6400, which it is not (it's PC2-8500 or F2-8500). And because the PC2-6400 has a max bandwidth of 400Mhz, I set the FSB at 380 and up until now it worked fine, but if I try and go as much as 385 the OS won't boot. At 390 my computer won't even get pas the POST screen.
"Fine", I thought to myself, "gaps happen sometimes. I can surely just jump ahead to 410 and it'll work". I was wrong, as any setting above 390 won't work - the computer doesn't even get to show anything on screen before it's restarting itself. And of course, I tried these settings with multiple values of clocks, SPDs and ratios. It just won't work. The voltages are fine, the memory receives every bit of the 2.1 it requires.
So I'm asking, what's wrong with my RAM? How could it possibly be registered to stop at 400Mhz? It should provide a lot more. Are the sticks faulty? Was I scammed into buying PC2-6400 instead of 8500? If it's the right sticks - how do I get the system to recognize them like it should?
Thanks,
Yoav
