FSB vs MULTIPLIER; HT LINK SPEED AND NB SPEED

post #1 of 6
Thread Starter 
in relation to above situations, here is my rig specification: 990 extreme 4, phenom 2 x2 550 BE, g.skill ddr 3 1600 cl7 7-8-7-24
1) knowing that phenom runs at 1333, why cant i run it at 1600 7-8-7-24 2T? all i could reach it 8-8-8-24 2T
2) i know that NB speed should be RAM actual speed (800) x 3= 2400. now it runs at 2000, should I increase it and how?
3) many say that HT link speed should lie 2000- 2400mhz but should not exceed the NB speed which is 1200mhz for now, how should i increase the HT link speed?
4) Current HT ratio given by the mobo is 6x and that is the lowest. what should i do? increase it? by how much?
5) Since I have BE processor, should i touch the cpu frequency or the multiplier or both?
6) lastly, what are the safe voltages of CPU and cpu-nb? should i touch the HT voltage?
thanks smile.gif

max voltage for both is 1.55v you wont need more than 1.35v for cpu-nb
best oc is usually using both reference clock and multi. if youre just beginning, use only the multi
ht link should be between 1900 and 2100 for best performance and stability. i dont know anything about a 'ht ratio'
cpu-nb speed, get it as high as it will go stable
your ram probably doesnt want to go that tight of timing. theres nothing wrong with running 8-8-8-24. you will not notice the difference

HOWEVER, i cannot get NB speed increased? how will i do it sir?

What mobo/bios? There should be a multiplier, or actual speed settings in the bios. My biostar has the actual speed listed, and I press +/- to change the speed. Need to add voltage accordingly.

My NB is at 2.6GHz, HT is still at 1.8GHz.

I've the same cpu and same ddr3. I've my NB set to 2100 MHz with a xXX multiplier. I think your NB frequency is too low and also OC with cpu base clock and multi is a magnitude faster then just increasing the multi. I've cpu base clock at 240 MHz and x13.5 = 3240 MHz Cpu frequency. I think this called FSB OC.
