FSB seems low. Am I missing something?

[Tyler_Durden]

Here are my specs:

945 Phenom 2 Deneb
OCZ Gold 4GB (2 x 2GB) 240-Pin DDR3 SDRAM DDR3 1600 (PC3 12800) Dual Channel Kit Desktop Memory Model OCZ3G16004GK

I used CPU-Z and it tells me my bus speed is at 200.7 MHz. This seems kinda low to me. My ram is running @ 1600MHz and according to CPU-Z it's at a 1:4 ratio. How can I set this to a 1:1 ratio. I checked in my BIOS and couldn't find anything like that.

Am I doing something wrong here? Hope I did a pretty decent job at explaining that. Here's some screenshots. Can anyone see anything wrong here?

thanks!
EDIT: sorry if it sounds dumb to some of you guys. I haven't been keeping up with technology.

Its call cool 'n' quiet, it auto downclocks the CPU to save power usage, when the CPU is in an idle state.

p.s. don't forget to post the pics from your build.

 

[AMDXP]

Post in the AMD section. Probably cool n'quiet, and you don't have to post pictures of your whole build.

 

[Tyler_Durden]

Oh okay, I'll try to read up on it a little more. Any thoughts on running it in a 1:1 ratio instead of 1:4?

Here's pics of my new rig:

CAUTION VIEW AT YOUR OWN RISK (old rig)

I plan on tidying up after everything looks good to go.

Go to your bios and disable the cool n'quiet.

No need, it will auto up-clock when the cpu is under load.

Run something that will task the CPU and look at CPU-Z again while it is running.

 

[Tyler_Durden]

Okay, I ran Prime95 while looking at cpu-z and everything stayed the same. There's a setting in my BIOS called HT frequency. I have it set to auto. Should I change it to 1600MHz (same as my ram), or should I just leave it alone?

 

[lt_shiro]

install AMD overdrive and check it again.

i will find the bios option to disable in a momment, if it is the problem.

look at page 54 of your manual.

 

[Tyler_Durden]

Okay, so I installed AMD Overdrive, ran Prime95. The core speed was about 800Mhz idle and 3 gig while running Prime95. I'm guessing the HT ref. clock (200MHz) times the multiplier (15) equals the processor speed. What I'm trying to figure out is how to get my fsb and ram running 1:1 instead of 1:4. Or whether or not I should even worry about it at all.

oh sorry I mis-understand, what you were asking.

HT ref (FSB) on AMD doesn't work the same way as Intel.

its its an amd feature called cool 'n quiet.. it is designed to drop the multiplier on the CPU so that at idle it runs at 800mhz.. the second there is any load it will start increasing the multiplier to the needed level.. it also has the ability to only raise the multiplier on 1 2 or 3 cores instead of forcing the entire processor to go from idle to full load to idle again.. this same feature on intels processors is called speedstep..

unless you plan to overclock the processor using the multiplier to raise the cpu clock leave cool 'n quiet on.. but if you do plan to overclock with the multiplier you need to turn it off.. all the options are in your bios.. if you overclock using the FSB then you can leave cool 'n quiet on.. with your current processor the 945 does not have the unlocked multipliers.. so you can leave cool 'n quiet running with no problems..

the FSB on amd processors is always 200mhz and will never change.. the HT link(the bottom number shown in cpu-z below the bus speed) is the same as intels FSB rating they used on their older processors pre intel i7.. though it doesnt work the same, it is similar.. as for the HT link clock LEAVE THIS SET TO AUTO unless the system is unstable.. the phenom II's can handle up to 2200mhz on the HT link clock.. so unless you plan to exceed that.. then you would have to change it from 2000mhz to 1800mhz.. your HT link clock is effected by your FSB so default its set at 10x or 200x10=2000mhz.. so at say 230mhz FSB you want to set the HT link to 9x.. so 230x9=2070mhz.. at 260mhz FSB you want to set the HT link to 8x so 260x8= 2080mhz.. so hopefully this gets the point across so that you can keep your HT link clock at 2000mhz which the default speed for the phenom II 945..

and for the last tid bit of information.. there is no such thing as running anything 1:1 on an amd system.. so anything you know from intel overclocking.. completely forget about it because none of it carries over to amd overclocking.. they are 2 totally different worlds..

 

[Tyler_Durden]

Thanks for clearing that up. Appreciate the help fellas.

 

[sirmonkey1985]

no problem.. its actually quite depressing how many members here dont know about amd technology or overclocking.. but trying my best to change that


btw if you want real time data on how the cool 'n quiet works.. load up amd overdrive and watch the cpu section of it and you will see how each core can independently change the multipliers while under certain types of load..

or site reviewers that get to HT 240 MHz, where everyone else is getting 280.

or site reviewers that get to HT 240 MHz, where everyone else is getting 280.

very true.. there are almost no hardware reviewers left that remember how to overclock an amd processor.. quite sick of seeing reviews with phenom II chips getting these mediocre overclocks on them.. when 1000's of people have already shown they easily exceed those overclocks on the same exact hardware.. along with even more that dont know how to overclock a processor using the multiplier.. when the 940 first came out.. almost every review i saw showed the processor overclocked using the FSB.. and the phenom II's suck at overclocking with the FSB.. because they dont know how to downclock the NB..

just the northbridge alone.. every 200mhz its overclocked = 2-3C more in temp and then they wonder why the stock cooling couldnt handle 240x15(3.4ghz) with everything set on auto.. thats a wopping 2100mhz just to the northbridge on a chip that came stock at 1.8ghz.. that alone is 4-5C increase in temp on a chip that uses a preset max temp unlike the intel chips that use a TJmax.. (btw the temps i explained were references from my overclocking done on my 940 using a thermaltake big typhoon VX so on stock cooling it would most likely be even higher)
