I'm just a bit confused on FSB vs memory speed and performance we get. I'm not a noob in oc but it's been a long time when I last oc and it is my setup you see below. Since then it seems there is more options to look at then before.
Let's take the E4300 for exemple since it may be what I'll get soon.
So in order to achieve a nice oc is to find the max CPU speed being carefull using lower FSB and mem timings. So let's assume you can get 3.4GHz from the 1.8GHz original speed. Take into consideration that I will then clock it at 3.2GHz and that will be plenty enough for me and very safe too because i really don't like being border line.
Next we try to find max memory speed depending on memory we get. That the part where I'm not sure. If I should go DDR2-800 or 1000 because I don't know how impact it has on performance. Also I know a 800MHz 3-3-3-8 should give better result than a 900MHz 4-4-4-12 but I may be wrong. Of course if we talk of very low speed increase (3%?) going 1000 then I would not waste 200$ for such modules. What you guys are heading to when it's time to get memory these days?
Then come the FSB and this concern the chipset too so again finding the top speed is our 1st goal. I heard that the upcoming P965, 975X revisions will handle up to 500MHz fsb. I read some stories about bootstrap(?) and also some internal timings change when you go from 420MHz to 421MHz and that 420MHz will be faster than 421MHz because of those timings change we cannot control and that you need to be able to get 450MHz to get results that look like the 420MHz speed. Well again let's presume I we hit a wall at 485MHz so again to be secure I'll go with a safe 466MHz.
Now I need to find the multiplier and 7*466MHz will give me 3.26GHz that is close enough to my safe determined value of 3.2GHz I was looking for.
Now should I look for (2*466Mhz) 932MHz memory module than will handle 4-4-4-12 or use a 1.5x and run DDR2-700MHz with better timings like 3-3-3-8?
There is so much possibilities that this is where I get lost. Maybe all this only represents a very very small performance increase that I shouyld not bother that much other than getting a decent CPU speed? You tell me...
Maybe it would be much easier, less expensive and clsoe to be par on performance going 3GHz with 9x333MHz FSB (2.5x for mem give 833MHz)?
Ok I'm ready to listen and read what you have to say.
