Overclocking stuff that I don't know what they are

post #1 of 7
Thread Starter 
hi there every 1:

This is my 1st time , and i'm new here, so if u please Explain as much as u can if u please.

Well guys, i've been able 2 OC my CPU from 3.0 Ghz to 3.75Ghz, and i did that by increasing the FSB from the BIOS, from 200 to 250, my Multiplier is 15, by the way my Ram is DDR2-667Mhz.

Now, when i increase the FSB 200-250, the Ram Frequency increase from 677-833 MHz, and my PC is stable, but in CPU-Z software when i c it, i find the FSB : DRam under the memory section is 3:5, and the Frequency is 417 , and the # under them r 5.5.5.15, (i really don't know these stuff but i know these # if they r low it means better).(CAS/RAS/RAS to CAS/RAS precharge)

Any way, when i go 2 the Bios, there is something call System Memory Multiplier, i can use only , (2 , 2.66 , 3.33 , Auto), and if u do the math u'll find, (250*3.33 Or Auto =833) , when i change the Multiplier to 2, it'll be (500), when i c the CPU-Z , i get 1:1 , and the Frequency is 250, and the #s are 3.3.3.9, and if i use 2.66 it'll be (665) MHz, and in CPU-Z i get 3:4 , the Frequency is 334 , and 4.4.4.12.

So can any 1 tell me what is going on, and what is the best choice for me, they r all stable, i got no problem with them.

But i was thinking, is it right when the Memory Freq higher this should be better,, y when they r high these # get higher 2 ??????

First of all, what kind of RAM do you have that gets to 833 MHz?! The higher the memory speed, the faster it runs (i.e. 833 is better than 650), but those other numbers are also important. Those numbers are your RAM latency, and you want them as low as possible. There should be options in your BIOS to manually set the timings on your RAM.

833 is the RAM speed with the multiplier, sir

NO man it's with out the multiplier, it's on Auto, or 3.33, witch gives me the same as Auto.

Ummmmm...........

Ok, I'm just going to play my ignorance card. Thank god I still have it. Good thing I'm still not fully understanding of RAM yet (especially in Intels), so I can actually have an excuse haha.

If I were you I'd benchmark your rig at the various settings (1:1, 3:4, 3:5) and see which gives the best results.

Personally I would avoid 1:1 as it would make your RAM run slower than it's optimal speed of 667MHz.

OK,In your bios, hit ctrl and F1. this opens up the advanced settings. in the clock control settings you will have new options to chose from. They will be set on Auto. Change them to lowest settings possible(3-2-2-8) i believe. Now try your multiplier at 2.66. Your ram will nbot run faster than 667. so a 3:5 should work ok with 250fsb. Check out stability there. If not good, then set timings to 3-3-3-8 and so forth.
