My CPU ht voltage is on stock voltage also when your nb increaces you need more mother board nb to be stable when you oc using ht mulitplyer you also need more nb voltage to be stable but when your ocing FSB and ht increaces i don't think you need extra mother board nb to be stable

You could probrally get a higher fsb settings try keeping nb on stock frequency or a little bit less and most of the time ram holds you back so losen the timings you could get to a point that ram becomes unstable even if you lower the ram frequency and that is as much as your ram can do
make sure that your nb is higher than your ram frequency or it will not boot up best to have about more than 10% higher nb frequency than ram frequency if your ram frequency gets so high you have a low nb frequency and it will not boot then increace the nb multiplyer and probaly needs some more nb voltage and mother board nb voltage for the nb to be stable(My FX4300 has a stock nb of 2000MHZ and i can get it up to 2400MHZ stable on stock NB voltage and with 300FSB but i can get 2700 MHZ on 1.31V NB but when i try to go over 2800NB i need much more voltage at least 1.4V and thats where you should stop oc your nb frequency since you need too much voltage for it to be stable)

Have myn stable at 310fsb. Its actually pretty easy to do. Just bump your NB1.8V voltage to 1.85v or less if you can. Make sure you put your ram at 1600mhz or less. My nb voltage is at stock for 2400 mhz, and no reason to g over that unless your ram is overclocked past 2400mhz. HT i have set at 3100mhz 2 bumps up past stock voltage. Can get it to boot at 3800~3900 and runs fine, but the system seems sluggish. Should run some benches with HT at 2700, 3100, 3900. But i know that iv read time and time again takin your HT mhz that high never does anything for benches or performance. Now i wonder if it would for tri sli or xfire... anyways since your 2 hours stable at 1.6v. Why dont you bump the voltage down 2 steps and see if u can keep the system stable for 20 minutes. Then bump it down 2 more steps test for 20 min. Do that till u find a lower voltage. Keep it cooler and less stress on it. Ram, well its not going to help your oc to have higher mhz ram. Anything over 1866mhz and your imc gets to much stress put on it. So your overclock will suffer. 1866 or less with tighter timings will do better for benchmarks, but for keeping higher minimum fps in games, you need higher mhz ram. Sorry for grammar and punctuation. hard to write this all on my phone.

I could also to manage to get 310 stable also could push it to 320fsb but not that stable pushed to 324FSB max when i am at 310fsb i need to have 12-13-12 ramtimings and undercloekded nb to 2500.... ht 4000 didn't want to mess around so i put it back to 300fsb since it is most stable (did 21hours of stress)don't think my cpu could run stress on any lower voltages at 4.8GHZ
I could probaly get past 350-400fsb with a 2400RAM since now i am using a 1600+1866ram

I tried lowering ram frequencys but dosen't help with stabibility even if it dosen't go past stock ram speed
Since at 300FSB my ram is at 2000 @ 10-11-10-31-41-2t not much point for me to under clock for tighter timings since the timing now is pretty tight
Sorry for making another post i was supposped to edit my old post but pressed the wrong button and made another post

Your using 2 types of ram. *** im suprised your even able to get anything stable. With your cpu voltage. Ubneed to test it stepping it down one or two clicks at a time. Then stress it for 20 minute s untill your stress test stops or bsod. I run my system at the same settings and my cpu stays at 48c, cpu package is at 58c, nb around 49c and motherboard at 26-28c. Thats with it being summer here and it being 80% humidity. So im quite happy with temps. Being at 75c, that not only is super bad for your mobo and cpu but it being that hot can hamper performance.

Yeah I know so many people already had warned me about it like cpu degrading etc i am half way in lower my cpu voltage and gonna lower my mother board nb from 1.66 to 1.4V if it is stable thumb.gif
Half way there CPU voltage clocked down to 1.548V @ full load 4.8GHZ (tried to push it to 4.95GHZ but could pass stress test)
also go my mother board nb voltage down to From 1.66V down to 1.31V matching my cpu nb which is 1.31V
Gonna try stock motherboard nb voltage and gonna leave stress test over night on occt lagre data set to check stabibilty
Hey thanks guys today i learnt something new is that when you got stable settings lower cpu voltage again and stress test again
Tried stock motherboard nb and couldn't boot up so left it at 1.31V
I am still not sure about CPU degration though i rembered that i did large data stress @4.8GHZ 1.6V and failed at 40mins but after i streess tested for 21Hours i could do large data set for more than 2 hours
I don't think cpu would degrade if it is not running over 80 or 90C core temps
what do you guys think what temps could probaly degrade CPU

Hey guys no luck on 1.548V or 1.56V failed the stress about 20-50 min
Currently testing at 1.572v

The system doesn't have traditional FSB. All you are overclocking the piss out of there is a reference clock generated by the chipset. Running higher base clocks (incorrectly refered to as "FSB" throughout this thread) does nothing for performance in and of itself. Better RAM will have no effect on hitting higher BCLKs. A high BCLK comes from over-volting and properly cooling a luck of the draw chipset.

My 970 chipset will generate 300mhz reference clocks with 1.25V. Yay,. Doesn't do anything but change all the ratios used to get to the same destination. Mostly a novelty IMO. Overclocking the BCLK for the purpose of overclocking the BCLK is like making a number bigger for the sake of a bigger number. I don't see the point (beyond novelty)

The 4GHZ HT link speeds are very interesting, should alleviate any bottleneck between the system memory and PCIE GPUs if you're running multiple high end GPUs, otherwise I wouldn't bother pushing so hard on that bus.

I am using 2x HD7850 2GB cross fire
I pushed the FSB cause lower multiplyer and higher FSB has less stress on CPU so that basically means you can push a few more mhz out of the cpu with same voltage
