Overclock i3-2120 + DRAM Ratio: FSB + Asus P8H77-M
-
Hello everyone, how are you? I'm trying to understand a bit about the DRAM:Fsb relationship... but I haven't had much success... My idea is just to increase the micro frequency I looked in the bios, and I saw that I have the FSB unlocked (which by default runs at 100mhz) the problem is that when I increase this, it also affects the speed of the memories... (the same are 1333mhz)
here, I tried to increase it by 10% (from 100 to 110mhz), but as you can see, it affects the memories. It doesn't let me set them to the standard speed (that is, 1333) The DRAM:FSB ratio I have is as follows 
I would like to know how I would have to do to take the micro from 2300mhz @ 2500/2600mhz (about 10%), without affecting the speed with the memories... Any ideas? Thanks in advance!!

Hello. Have you read any O.C guides?
I think not, right?
Otherwise I think you would know something about synchronous and asynchronous
And it's sad that I'm telling you this, I've only read 2Greetings and read a little bit

Looking around the forum a bit and I found a couple, you can check out one of the greats in this forum Bm4n which is quite comprehensive and has a few links that might be very useful for you

First of all, I see that you have it 'clear' writing between lines, but not yet to read them..
I agree with this, thanks for your help (Y).For the rest of the people, I'll say that the first thing I did was look at some posts here..
I easily came to the user "Bm4n"..it's clear that he is really one of the people who knows the most in this forum..
but even so, I still don't understand the relationship..how it works and how to modify it..
I would appreciate your help!Greetings and thanks!

Roughly speaking, you have to lower the least so that when you do the OC, you get the same value

Basically it's very simple, as you have increased the base clock the ram has also increased in speed, and what was 800 is now 880, and what was 1066 is now 1173, and of course with 1333 it has also happened to 1466.
So if you keep increasing the base clock little by little, you would reach a point where now the ram is at 1173 and that originally was 1066, by increasing the bus enough you would reach 1333, and then you would reach the first point of base clock increase where the ram coincides again at 1333, neither before nor after.
If you had the micro's multiplier unlocked you could overclock it without moving the ram an inch, but if that's not the case and you have to overclock by base bus you have to stick to finding the best possible relationship between micro and ram if the micro doesn't go up enough to reach the first level where the ram fits again at its original speed.
If I'm not mistaken, by increasing the base clock to 125 the second level of memory (where in the image it says 1173) would give 1333.
With this last you have the practical info to get to the point and increase the micro while keeping the ram at its speed.For the rest, I assure you that the huge amount of guides and useful information available on the internet is more than enough for anyone to understand it. You wouldn't like to always repeat the same thing for the sake of art either, right.

thanks for the data!
I'm commenting on what I've found so far...
according to what I understand, if, let's say, I want to make the CPU 9% faster
I would have to change the FSB from 100 (stock) to 109mhz...
the current ratio is:
20:3 = 6.66666667 x 100mhz= 667mhz (real speed = 1333mhz effective)
now, if I want to set the FSB to 109mhz... I would have to look for a ratio...
could it be this one?
49:8 = 6.125 x 109mhz (FSB OC) = to 667.625 real (or 1335mhz effective)
Would this ratio be good?.
If I'm more or less on the right track, haha, I just need to modify this ratio (from 20:3 @ 48:8)
In case something goes wrong, tell me!
Hugs and thanks!

depends on the proportions allowed by the plate.

Yes, that's correct..
The first thing I did was look for that relationship..
put the bus at 125 and there, the 1333mhz coincided..
but it seemed like a lot to me, besides I have the stock cooler..
I only want to increase it by 10, 12%.. more than that, no..

it depends on the proportions that the plate allows.
mmm, and to test..
how do I change the dram:fsb ratio?
I went into the bios, but I didn't see an option to modify it..
-
mmm I didn't have the pleasure of "tasting" that motherboard, someone else maybe can answer you, and maybe those levels you see are the only ones. The relationship that comes out in that screenshot you put can be calculated by the program by seeing the values that are there, it doesn't have to be like that in the bios menu.
The motherboard manual?…..
PD: I also tell you that to raise it by 10%..... why?

encode?
anyway I'm going to go into the bios again, to see if I find something..
thanks in advance!

While it is true that it is better to do the OC by BIOS …. Why don't you try the Turbo V which is from Asus and will increase it between 200 and 300 without problems. And besides it allows you to have several OCs
For example I have a Phenom 9950 at 2600 for Internet I put it at 1000 (the minimum) for other things at 2000 and for playing and auto cad at 2800/2900 and no problem

encodear?
igualmente me voy a meter otra vez en la bios, a ver si enuentro algo..
desde ya, gracias!
Encodear/codificar, vale muy bien, entonces te seria interesante subirlo mas, no solo un 10%.
Yo me compraria un disipador, que entre 30 y 40 los hay muy decentes, y a partir de hay ya hacia un overclock completo.
Y como te comentan puedes tener diferentes ocs para diferentes necesidades, incluido uno mas agresivo, pero con 10% la diferencia es poca todavia.Tambien te comento, si esas codificaciones que haces no requieren mucho de la ram puedes subir el micro para codificar aunque te quede la ram baja (solo para codificar), pero si por el contrario la codificacion usa mucho la ram y acusa su velocidad, entonces no tocaria nada hasta que no pueda ponerlo a 25% mas como minimo.
