cpu frequency

October 6, 2010 at 06:25:41
Specs: Windows 7 home prem, dual core 3.0/1gb
i overclocked my cpu from the bios. im pretty sure i did as it was reflected in the bios but when i check my computer properties on windows, the frequency is unchanged.

also, my ram is a ddr2 800 but when i check on speccy, its only running on 440++. how come?

List the system specs.
Ddr2 800 is capable of running at 400/533/667/800mhz ddr. "440++" actual frequency (440 x 2=880mhz ddr).
use cpu-z.

DDR2-800 runs at 400MHz frequency....800MHz is the data rate. If the memory is running at 440MHz, you've obviously increased the CPU frequency.

440MHZ is like 880MHZ effective 440mhz is the actual speed of the ram that u overclocked throghout the cpu
kuwese mentioned cpu-z which is a perfect program for u to see

i downloaded cpu z. dram frequency is 423mhz. so what i understadn from the pervious post is that if its a ddr2 ram then the actual speed at which the ram is working is twice of what is reflected on the frequency? so for a ddr3 it will be 3 times?
Another question i have in mind is the my mother board only supports up to a 800mhz ram but if i overclock it will it be able to support a higher frequency ram?

to answer the ddr3 question actually a lot of ppl think the same way that u thought of but unfortunately ddr3 is faster than ddr2 but still twice the speed
like maximum for ddr2is ddr-800 and for ddr3 is ddr-1333 see the difference
but not all motherboards support ddr3 which is the faster ram these days.
and the second question no when u overclock u wont make the motherboard supporting more than what its built to support if its built to support ddr-800 maximum than thats it u overclock a bit but u wont reach like ddr-1066 which is supported by other boards

oh alright. then how come they relfect just 400mhz on cpuz when its running on 800mhz?

ill answer this by a question
why do they write DDR2-800 ?
DDR:double data rate (effective speed).
its not the actual speed the ram is running at its the effective one the real speed is 400MHZ which is half 800MHZ
800MHZ is the theoratical speed
so its not running at 800MHZ its running at 400MHZ
ill give u this example DDR2-667 is actually running at 333MHZ the 667 is double 333mhz which is theoratical thats why they write DDR2-667/DDR2-800

so does this apply for ddr3?
because u said on your pervious post that its a misconception on my part.

yes the same thing applies on DDR3
i said u did not have ddr3 u have ddr2 thats wut i said and yes its a misconception that ddr3 is also twice but faster than ddr2
