overclocking FSB and memory

[wjgollatz]

I have never overclocked before. I am buildign a new system, and as it turns out, the chip and the motherboard are well suited for overclocking, and the motherboard itself may be able to overclock the FSB as well.

I want to optimize performance of a RAW image editing application, Nikon Capture NX2. Seems the bottleneck in the application is the FSB. The software is reliant on the CPU for editing, and I was told in some dual core systems, the cpu's are less than half load.

What issues would I need to catch up on to overclocking the FSB. I imagine that would also require overclocking the CPU and memory? Would I need any of the cooling items for the RAM?

Right now, I plan on using the following for a budget system, I haven't decided on memory. The CPU is a 800 FSB (and the motherboard is also 800 even though newegg does not list it as so). Moving up to a 1066 FSB is another $50, put maybe I can safely overclock it faster.

I have no idea where you got the idea that fsb is going to limit your performance. Just so you understand: FSB * CPU multiplier = CPU speed. And you have to divide the "Intel CPU FSB" which they label as "Quad-pumped" by four to get the actual system fsb. So, for the e5200:

800/4 = 200 (system fsb)
200*12.5 = 2.5GHz

It seems to other users of this application that the transfer between the RAM and the CPU is a bottleneck in the application's performance. I will not need to overclock the CPU for extra performance, just increase the data exchange rate with the RAM, unless increasing the FSB requires the increasing the CPU. (Another bottleneck may be the data exahange with the HDD also). That is my understanding. I don't know much about overclocking, just trying to maximize a budget system. I would rather put extra money to a lens for my camera than better hardware if I do not need to.

Did you read the above? Or the forum sticky that Gillbot linked? I wonder sometimes if posts like these are a joke. There's no shame in being inexperienced, but the resources you need for understanding are right in front of you and a Google search will unearth mounds of information about how overclocking works.

See Denithor's post. Increasing the FSB increases the CPU speed proportionally, and typically the RAM as well. Changing the CPU multiplier and the RAM divider, you can determine just how much the FSB affects the speeds of both. However, it sounds like you're talking about overclocking your RAM. You can do that just by adjusting the memory divider so the RAM runs faster at the same FSB, leaving the CPU alone. What RAM are you using? It may not even really be capable of significant overclocking.

In any case, I don't think you're going to see a massive performance increase in any application just by overclocking your RAM. You would probably see more benefit from CPU overclocking and buying additional memory.
