Is this a bottleneck?

Hi. I was wondering if I have been sold a notebook system with major limitations. I purchased a Toshiba A505-s6965 notebook about a year ago. The specs that are stickered to the laptop read: Intel Core 2 Duo P7350 (2.0ghz) with 4GB of RAM. After having some performance issues when using it for trading, I researched it a little bit. It turns out that for trading it is good to have a fast FSB. Well, here are the actual; specs: 2.0GHz, 3MB L2 Cache, 1066MHz FSB and a Mobile Intel® GM45 Express Chipset. My question is regarding the maximum speed I can achieve from my RAM. the RAM in the system is DDR2, and the highest speed I can purchase in this type RAM is 800MHZ . This sounds like a bottleneck...no? If this is the case, can the computer actually perform at the stated 2.0GHZ? Your great comments will be much appreciated.

Sure it will. Cpu speed and ram speed are completely independent of each other, as motherboard bios' have built in ram multipliers. Most ddr2 is 800 speed, and most boards won't run at 1066 unless you overclock the cpu by 33%.

A higher FSB on the ram helps for reaching a greater CPU overclock.. But that is more of a desktop term.. Your notebook is performing fine.. If at all, the automatic clock control programs are creating some niggling issues.. Turn then off in the BIOS.. That way, your CPU will stay consistent with the 2GHz clock speed and will never drop down..

My guess is that the performance issues are more likely a result of all the bloatware that came pre-installed with the system.

No, it not a bottleneck. Your FSB is 1066 so the actual speed is 266. Multiply this with 2 and it will give you the speed that the ram is running which is 566. So actually your ram will run at a slower speed to be sync with your cpu so you are fine.

Hi everyone, thanks for all your comments. I learned a lot from them. I have decided to upgrade my system entirely. I am having a Core i5 - 760 computer built. Thanks Cory
