what is L1,L2 cache make any difference in cpu speed?

Hey all, I'm sure there's an obvious answer, but I'm finding myself drawing a blank. Why are there different multipliers for CPU's? Why isn't there a standard for this? I know CPU's operate at different speeds, with those multipliers representing the ratio of internal:external speeds, but why...

I'm looking to order a Toshiba Satellite P740-BT4N22 and have it custom built to my specs. I've decided to go with the Intel i3-2310m processor and right now they are including 6GB DDR3 1333MHz SDRAM for free. A local computer tech told me that I need to stick with either 4GB or 8GB of RAM with...

Hello, Where can I find engineering measurements for ATX case standards. For example, the the height and spacing of where the expansion boards screw into. Also possibly a template for the motherboard standoff, screw and tap size. Thank You. Bill, St. Louis, MO USA

No one seems to be addressing this issue. From my very limited understanding of this subject if you have an active PFC power supply you need a pure sine wave UPS to actually provide power interruption protection. Those are quite a bit more expensive. Is a one of the main benefits of active...

I was experiencing random crashes (reboots) when playing games. So I ran GPU and CPU stress tests (at the same time) and very quickly the CPU reached 85c, so I stopped and I assume that the CPU is the problem. GPUs never got above 65c. Build: ASUS P8Z68-V PRO 8GB DDR3 i7 2600k (stock cooler) 2x...

Hello all: Someone suggested that my CPU (Q6600) was bottlenecking my system and that upgrading would give my computer a boost (I primarily use it for gaming and CAD) System: Q6600, 650il chipset, 4GB DDR2 800, ATI/AMD 5850. I assumed that the CPU was 'good enough' not to affect games or...
