Hello. I am looking to take my OC a little further by means of fully understanding the concpets involved. I have some questions that I'd be very greatful of the community answering. My CPU-z readings are atthe bottom of OP.
1) When setting the Core clock (My fx 8370 is 4.0GHz by default - my current OC is 4.575MHz, 1.332v) - Does it make a difference how you achieve said clock? I have learned that there are two ways of increasing the Core clock; increasing the multiplier (Which I have left at 20.0), and/or increasing the Bus (which I have increased to 228).
The reason I am asking this question is because; Increasing the BUS also increases the; memory frequency, HT Link freq and the NB frequency, where as increasing the multiplyer ONLY increases the core, without effecting the RAM/NB. I can see how you would adjust those two things to finetune an OC, reaching the same core with lower bus setting by using the multiplier etc. Therefore, increasing clock without stability issues elsewhere (HT link, NB etc).
Is this how its done? Or, is there a benifit to reaching desired core freq one way or the other?
2) Fine tuning RAM, HT Link and NB freq. My fx 8370 (as far as i can see in bios, because its not black?) doesn't allow me to alter the multipliers of HT Link, NB and RAM. I am limited to choosing the preset ratios within the dropdown menu. These presets have big jumps from one setting to the next.
I have read that my NB Freq must be three times higher than my RAM. However, I am having to run my RAM at a lower speed than optimal, because I cant keep the NB stable. (At least I think thats the instabilty I am seeing). Is this a usual thing?
I have increased Voltage to the NB, but my temps are at a point where i am reluctant to go any higher, (72' Socket, 60' Core after 20 mins stable prime 95 blend)). So, as a trade off, I am forced to run my ram slower to achieve 3:1? Or in this scenario, is it best to just run everything as fast as individually stable, ignoring the 3:1 ratio?
3) I have read conflicting things regards performance gained by increasing the HT link and NB freq. What would you advise? Is one more important than the other?
4) I am having a little trouble searching the exact spec of my RAM. I no longer have the box to see the spec. Obviously, I am using CPU-Z, and In the SPD menu (slot 2 or 4) it says MAX Bandwith: PC3 12800 (800 Mhz).
Can I trust that this is the default Ram Speed, 800? (2x800) = 1600?.
If so, by default, my Ram should be set to 1600 and my NB to 2400?
MY CURRENT OC is;
4575 MHz at 1.332V (Temp: 72' 60').
Multiplier: x20.0
Bus: 228.8 MHz
Rated FSB: 2516 MHz
NB Frequency: 2516 MHz
DRAM Freq: 765 MHz
Voltage to NB: Will have to edit this is as I cant see BIOS right now!
Thanks for reading, regards.
Ps. My cinebench score (8threads) is 734. Is that good?
