Finding the bottlenecking component

post #1 of 4
Thread Starter 
Intel QX9770
Sapphire 5850HD
GA-DS5-X48 (Gigabyte motherboard)
4GB of kingston ddr2 800mhz
EarthWatts 500 Watt power supply

This computer is 5+ years old, and my guess is that the bottleneck is because of the power supply if anything..
Examples of the fps problems:
Cod4 - 60ish fps in a smoke, 700 fps when looking into a wall, ground etc (high fps cfg, 800x600 resolution)
World of warcraft - 10-20 fps on ULTRA (1680x1050), 70 and lower fps(mostly lower, I get alot of 20's) on LOW (1680x1050)
A lot of old games share the same problem on this computer..
Recently changed my memory so it wouldn't be the problem.

Thanks in advance, hoping for something or else i'll have to upgrade tongue.gif

Its the CPU, or more specifically, the interface between the CPU and the rest of the system.

See, when intel made core 2 quad, they got lazy and didnt create a dedicated internal interconnect between the two dies (yes, core 2 quad has 2 dies, intel only made a monolithic quad core with the first gen i7s). As a result, that data has to be shot out to the northbridge then turned around and sent back to the other die in the package. On top of that, the FSB the processor is using for inter-core communications is ALSO being used for memory communication via the northbridge, which by itself can completely saturate the FSB.
And then there's the fact the CPU needs to crank data out to the GPU so it can chew through it and put stuff up on your screen, which puts further load on the FSB.
On top of all of that, the design of FSB itself means that it is not full duplex (can send and receive at the same time) unlike QPI, which is FSB's successor. So, here you have two processor dies communicating with each other, communicating with the ram, communicating with the rest of the system and being able to only read or write to one device at any given time, means that the 12.8GB/s interface between the CPU and the rest of the system becomes very clogged very fast.

If you want to eliminate that bottleneck, you must upgrade to a more modern CPU that has an integrated memory controller, and with that, a better board and ram.

Basically you need to rebuild your system.

Alright, thanks a lot!
I'll probably get a new system in a month or two, need to save some money smile.gif
By the way, some knowledge you have, didn't expect such an informative comment biggrin.gif

Hey, i try to help the best i can.

And if you want to at minimum make some money back after getting the new system, sell your current system core. The board alone will fetch easily over $100, and the processor can get double that. I'd buy them off your hands to upgrade my own LGA 775 gear but I has no money to do it with.

Anyways, if you need any assistance in picking out suitable parts dont hesitate to ask. Me or someone else will give you the info you need to get it done.
