WTH is AMD boost?

It's my secret weapon when wanting high benchmark scores... :nutkick:

Seriosly I don't know how it works. Fusion has the AMD Boost option and AOD has the green button the right upper corner. It raises idle temps very much.

Sorry guys sorry, I got confused with AMD Fusion. SOrry.

AMD Boost is the same as CPU Tweak. Sorry, I deserve something thrown at me hehehhe :roll:

Looks like I'm going 3.4G now with my Cores 0, 1 and 2, but my Core 3 is a real bitch. I should keep her around 3.2

I went back to 200 HT ref
Changed ACC to 0%

CPU NB VID gets the core much hotter so I decided to try something cooler and skip the whole NB speed, NB voltage... and leave them to 2GHz / x10

I am just a bit confused why AMD decided to use 1.8GHz / x9 NB/HT link speed with PhII

EDIT:

Have you guys tried the Nehalem Smoke Demo... it would be awesome to get clock to clock comparison with intel 4 core chips. In FPS of course.

you said PII you didn't say Phenom II or Pentium II :roll:

so i gave you a upgrade to a pentium III

btw thanks for the lol :toast:

Anyone see the new Athlon 2.7GHz Black Edition i wonder what kind of clocks i can get and for only $85 with free shipping on the egg its a steal

Please do yourself a favor and disable CPU Tweak. It drops temps by like 10ºc, thus giving you room to clock further

I now this but with CPU Tweak off it Cost many Performance for me.

can you explain what it costs you performance in? For example I only saw a big difference in super pi, and in 3dmark it wasnt much. But i rather have less heat, be able to clock higher, and get even more performance. Just my two cents of course.

i was thinking about buying some DDR3 but will it make a difference in my system?
around 6 or 8gb of DDR3 vs my current 8gb of DDR2 800mhz

OC help?

Hey CP, Guys...

Just as i said few posts before, need some help with OC-ing the crap out of the 9950... but instead of providing highest stable OC screenie i tought of asking you guys to go this way...
Heres a screenie of what i did just now, reduced ram from 1066 to 800mhz, and bumped FSB to 220, multi is at def 13x, and def voltage....

1) Now im thinking of doing it this way, not cuz i want to OC the crap out of it, but to better understand all the stuff that happens under the hood. So lets say i want to OC my CPU by just increasing the FSB... which settings would be the limiting factor (if we imagine that FSB itself is not the limiting factor)... im thinking of HT, SB, NB and so on...

2) As ive come to conclude, raising FSB increases HT speed too, so if i lower the HT frequency to lets say 1800mhz (opposed to 2000mhz stock) i would lower my HT multi to 9x and get FSBx9= HT speed? So following the example from the sshot i would get 220x9=1980mhz and thus remain ~stock while still getting higher FSB and CPU speed... am i right?

3) But how does NB core come into the equation? Northbridge is actually responsible for what? Im trying to look at this as simple as it can be, so im kinda interested in what functions does NB do, and whats SB's responsibility... There has to be a good reason in why and when the voltages on NB and SB should be raised....

4) In earlier years (older PC's) raising FSB also raised the speed of all the interfaces on the MB (eg. PCI, VGA, DIMM).. is that the case with the current hardware? I mean would a 220mhz FSB also increase the speed of my PCIe slots or not?

I know i have many more questions, but ill just wait and see what u guys have to say on the ones i already asked...

Cheers and thanks for helping out, Milos

p.s. RESPECT :respect:

Hi there Milos, and thanks for posting the SS:

now to answer your questions:

1- When you increase the FSB the RAM, NB, and HT clock higher along with the CPU. If you are going to use the fSB to clock try to keep your HT under 2000 MHZ and your NB at around 2000 MHz. This helps greatly with stability at higher clocks. The FSB itself has its limits, my board had a FSB limit of 285 MHz, higher than that it would not post.

2- you are correct. The HT link in the BIOS is a multiplier of the FSB. 2.0 = x10 / 1.8 = x9, etc.....

3- The faster your NB runs the better your performance, but like everything it has its limit. I could do 2400 MHz on the NB at about 1.16v on the NB, however to go higher you have to give it more voltage, which then brings temps into the scenario, but for stability I would keep it at around 2000 MHz, use the multiplier in the BIOS, it is also a multiplier of the FSB. 220 x 10 = 2200. The NB basically handles the communication between the CPU, RAM, IMC, etc.

4- When you raise the FSB the only thing that overclocks is your CPU, RAM, HT, NB. The PCI-E has a seperate clock in the BIOS, i reccommend leaving it at 100 MHz.

Very important, for now I suggest leaving the FSB at 200 MHz and using the unlocked multiplier to overclock. THis way you dont have to worry about the RAM, NB, HT overclocking. Its easier and you can find a comfortable clock on the CPU quicker. Once you find the clock on the CPU you like, then you can worry about the FSB and start to lower the multiplier. For example lets say you hit 3.4 GHz and thats the max you want to go. That will be 200x17= 3400 MHz, then you can do 206x16.5- 3400 MHz and so on and start going lower multi and higher FSB then you play with the dividers and keep the HT and NB in check. Hope this helps.

Here is a very very good guide to overclocking Phenoms, it has helped me greatly:

you would have to wait till the DDR3 Phenom comes out (AM3). DDR3 is fast bro, i'm using it now obviously in the i7 rig, they run loose timings out of the box but im running my ram at 1400 MHz

miloshs · Dec 25, 2008

Thanks for the input... and the linky...
Gonna read the stuff (really good stuff), and try to utilize it in my OC. I'll get back to you when my morale drops low again

Cheers, Milos

P.S.
Just a quick one... I presently understand everything but the relation between NB and HT?!Somehow from every explanation i've read i come to think of it as the same/similar thing???But im sure thats not so

no problem bro, and then I'll be here too! keep us posted.

miloshs · Dec 25, 2008

Okey-Dokey... I'm back...

Using the instructions from link You supplied I was able to find out the following:

- FSB Max = 256MHz
- Multi Max = 17x
- HT Speed Max = 3328MHz
- NB Max = ???

Now... i couldnt get MB to post at over 256MHz FSB, 17x was tops i was able to post... but HT speed made me wonder a bit since i saw most of the ppl hitting ~2600MHz HT Speed and not being able to go higher. Now im not sure if other ppl meant 2600mhz in-OS or POST-able... i'm giving You what was my tops HT MHz when i was able to post.. I got it by setting FSB to 256MHz and HT Link Freq to 2600Mhz (13x Multi). Strangely enough NB speed setting was nowhere to be found in my BIOS (maybe under another name, but ill get to that in a sec)... Thats why i'm giving you guys a few screenies from within the BIOS and maybe u can help me locate the NB speed thingy...

Now.....

1) This is the BIOS Genie section (tweak section) in my BIOS

2) HT settings within the Genie stuff

3)Voltages part of the BIOS

4)And the CPU section which i have no clue whats it all about? Any info on this one?

I'm now back to stock settings just to post here, and consult with you guys. Oh and all of the above numbers (FSB,HT....) were acquaired without touching the voltage settings. Do you think i should have tried those too, and maybe got higher MAX values???

p.s. These are not SS from my bios, but the ones taken from the PDF manual of my mobo. Not all off the settings are at the same place as in mine, but i can say they are 98% true...

Cheers, Milos

BTW what is the difference between CPU Host/HTT Clock and CPU Host/HTT Boot Up Clock?

BTW what is the difference between CPU Host/HTT Clock and CPU Host/HTT Boot Up Clock?

Welcome back

First off let me just clear this up, maybe you missed it in the guide. The HT will only run as much as the FSB is set to. So even if you set it at 2600 MHz (x13) the FSB bus was 256, meaning the HT link only run at 2560 MHz. It will never run greater than the FSB. To run it at 3328 MHz how the math will give you, you need to have your FSB at 332 MHz,not happenning :laugh:

These DFI boards are definetily very confusing as everyone says :roll:

but lets see what I can do for you:

1- first off make sure cool & quiet is disabled !!

2- what options do you get other than auto under CPU feature for "NPT FID Control"?

3- This is a very confusing BIOS hehe, try to get the 2nd question answered, and we'll go from there
