Hello there. I have a few peculiarities floating around my system that I can't figure out, so I guess it's time to shoot some questions.
What made me notice the weird stuff is the PerformanceTest 7.0 benchmarking program. Basically, I get the feeling that some of my PC's components, namely the hard drive, can't keep up with the CPU/RAM overclock even though I considered them to be unrelated or at least have directly proportional performance boosts.
Now, let me explain. As I was overclocking the CPU and RAM (my RAM speed is tied to the CPU
), I saw the performance of the HDD rise a bit in accordance with the CPU boost. Then I stopped doing HDD benchmarks - thought I'd surprise myself later. However, once I found my system's limit on stock voltage (can't change it
) and ran a benchmark, I noticed that my HDD performance dropped even below the pre-overclock level. By performance I mean the sequential read/sequential write/random seek&RW speeds. The drop wasn't much, only around 1%, but considering it was going up earlier... Well, anyway. After that, I ran benchmarks every few days and compared the scores to the initial post-OC bencmmark. What I saw was a slight drop in CPU and memory performance. The physics area in the CPU was the only one that dropped and when it came to memory, well, all the scores went down (allocate small block, read cached, read uncached, write, large RAM). As to reassure my suspicions, slowly but surely, the HDD performance reached the pre-OC level. Now, out of the blue, the CPU/RAM scores are the same as they were after I had just OCed and the HDD score dropped once again.
So, my questions are:
Just taking a wild guess here: could it by any chance be the fault of insufficient voltage?
Thanks in advance for coping with my TL;DR-ness. I've provided most of my PC specs in the system-signature-thingy below the post. If you need anything else, just ask.

So, my questions are:
- How is the performance of other components (namely the HDD) tied to the CPU/RAM performance?
- How come the HDD performance dropped, even though the CPU/RAM performance rose?(remember, it was rising at first)
- What could be the cause of the random performance power shift?
