CPU Bus speed 200Mhz

[ninjatuna101]

Hi my CPU Bus speed is running at 200Mhz is that too slow for an AMD 8320 8 cores at 3.5ghz each. my PC is running fine i just don't know if that speed is bottlenecking my rig or if it is just slow.

thanks in advanced.

It is the correct bus speed, when times the multiplier gives you the actual CPU speed.

oh okay i thought it was something completely different.
is it still a good speed or should i increase it?

Your bus speed is the speed at which your HyperTransport (or similar as AMD don't have a brand name for the system bus/base clock) is running, this is multiplied by the Clock Multiplier to set your CPU clock. It's basically like the hour hand on a clock, with your CPU clock as the seconds hand and the RAM clock as the minutes.

Strictly speaking it keeps all of your computer in sync. Your CPU (if it's the one in your sig) runs at 3.5Ghz, so your multiplier should be at 17.5x. If it is not allowing you to set multipliers with a decimal point, I would set it at 18 and call it a day, although strictly speaking, you would want to set your bus speed to 175 and then your multiplier to 20 to achieve the exact clock speed that your CPU uses.

Why?, becasue 3500mhz, your CPU speed, is the same as 20x175mhz which is your clock multiplier times your base clock (aka HT clock or system clock.)

200 MHz is the stock reference bus speed for AMD chips. Increasing it will OC your CPU and your memory as they are both referenced off of this bus speed. Your 8320 runs with a 17.5x multiplier so increasing your bus speed to 210 would increase its speed to 3.675 GHz, but the easier way to do that would just be to increase the CPU multiplier in BIOS since that will increase CPU speed without increasing the speed of other components which can induce odd instabilities.

Pretty well explained above but if you increase it you will overclock your rig. Overclocking your CPU is simpler just by increasing the multiplier which will not affect other things like ram.

Okay Thanks a lot everyone!!
i really appreciate the time and effort you put into this thread thanks gain.

you have a good motherboard and CPU, i'd suggest you set the multiplier in the bios to 20 or 21 (4.0ghz or 4.2ghz) and turn off turbo boost that way your CPU will always be clocked at a nice speed and provide better performance...most 8320 are stable at 4.2 ghz without increasing the voltage...

 

[ninjatuna101]

Okay so if I use Asus ROGs applications to do that and I'll see the results I get also I was checking my clock speed with cpu-z and it said core 0 was running from 1.4ghz then when gaming It went to 4.7ghz a bit confusing since it only goes to 4ghz on turbo charge. Is that normal?

 

[paitjsu sadff]

yes this is because some power saving features like cool n quiet are enabled in the bios and they slow down the CPU when it is idling to save on power and heat output...when the CPU is underload it will auto clock to max settings in bios....i suggest doing the overclocking from the bios of your motherboard and disabling turbo boost...

Okay then thanks again paitjsu sadff
