Hello! I have been trying my hand at overclocking recently and wanted to double check my settings so far to be sure i didnt mess anything up and perhaps i could fine tune it better somehow. Long story short, i had another thread about my throttling VRMs and that has been fixed by moving some stuff around and adding fans over them. I also have chosen to set it to 6 cores instead due to temps and the fact that games apparently dont use all the cores anyways. Under prime95 i get 62*C without errors, more like 50* in game i believe. Temps sit at 40*C at idle if i keep windows from letting it drop the frequency, but unless im gaming i let it thottle as it needs so temps stay more around 35*. This is also in summertime heat... Anyways, here are some specs and whatnot. Feel free to run while you can :p

-Antec 1100 case loaded with fans
-Asrock 970 extreme3 (i learnt this is only 4+1 phase, but ive managed to get a fan pulling heat from the VRMs and around the core which stopped throttling i had :/)
-FX-8150 with a H55 cooler (mounted in the upper slot behind the HDD trays to free up the VRMs. Dual cougar 1.6mmh2o fans running push/pull. Soon to be SP120 performance fans instead)
-4x4gb corsair vengeance 1600mhz tall
-Gigabyte 7870 oc edition
-1tb caviar blue HDD
-corsair TX750

Current overclock specs...

CPU freq: 200mhz
PCIE freq: 100mhz
Spread spectrum: disabled
Turbo core: disabled
AMD apm: disabled
X21 4.2ghz @ 1.375v on 6 cores
NB frequency: x12 2400mhz
CPU NB voltage: 1.2v
HT bus speed: 2400mhz
HT bus width: 16 bit

RAM clocked up to 1866mhz (xmp profile)
9-10-9-27

Load line calibration: auto
DRAM: 1.5v
NB: 1.145v
HT: 1.21v
CPU VDDA: 2.56v
PCIE VDDA: 1.81v

Cool+quiet: enabled
C1E: enabled
Secure virtual machine: enabled
C6: disabled
CPU thermal throttle: enabled

GPU also over locked to 1250mhz core and 1375mhz memory @ 12.6v (still have to play more to see if it's finally stable for good but it hasnt crashed yet at these settings after a few plays)

What do you guys think? Is there anything that sticks out to you that i should change or could possibly make better results with? With the above temps, should i try pulling a little more out of the cpu making sure i stay below 70 socket/60core without throttling issues again? I still get limited by the cpu, but i understand the h55 is no gem

I never used cpu-z before, but this is actually what I was going to ask about. I was wondering if there was a way to test if it actually makes a different with higher clocks and how much so I can weigh whether the temps are even worth it lol Ive been messing around with clocks a bit and am currently at 4.3ghz 6 cores @ 1.385v. Temps get to 66*C socket and 55*C on prime with that small increase. I tried 4.4ghz, but it wanted 4.25v and when temps got to 70 I bailed out. Anyways, at 4.3ghz I seem to do around 946 single thread and 4460 multi thread. Kinda cool that I can see a reference vs an average stock clocked 8150. Not sure how well I stand against others with this kind of clock. I'm quite a ways behind you but my mobo would melt if I even tried to clock that high :p

What is vdda and what does it do? Lol I never touched that because I was unsure what it does.

I only have the option for auto, 2.56 and 2.7ish anyways I guess. But it all seems to work at least lol

My score is on 6 cores and when I set it to my reference against a 8150 I see the multithreaded score is a good deal lower. But I figured that's the 6 vs 8 core and the overclock has boosted my single thread about 130 or so vs a stock 8 core

My vcore does drop a bit under load of course, but I thought that was to protect the CPU somehow? I could see lower drops making idle temps better as it doesn't sit higher than needed before the droop, but I don't understand how it could affect things under load as you'd still need that voltage to run the clock

Ok, ill have to look into it a bit more. But it seems so far like its better off just leaving it as is even if idle voltage is a bit higher. From my understanding, the vdroop is there for a reason so unless sitting at the higher voltage at idle causes instability somehow it seems pointless.

For my overclock, i see people overclocking either with the multiplier like ive done, or by increasing the fsb speed... The fsb speed is what my mobo has as "CPU speed", right? (currently at 200) ANd that is what gets multiplied to get the clock. And i also understand that it effects pretty much everything else like the ram speed and NB? Ive read that some people have better luck using the FSB, multiplier, or somewhere in between depending on the chip and setup. So maybe i should play around with increasing that slightly? From my understanding, id be best to set everything to stock aside from power saving stuff and slowly increase the fsb until i get stability issues. Then i can find the limit on the rest of the stuff before boosting the multiplier even more. Is this right? Maybe i should just try adding slight increases to fsb as is and see if i can squeeze some more without peaking temps too much?

Also, i caved and purchased an H105 that should be here in a couple weeks. I figure even if i changed chips i can used one of the other supplied brackets anyways. And ive always wanted one of those bigger rads lol I went with the h105 over the h100 because of my clearence issues with the video card where i have to mount it. I only have back behind the HHD trays to put it, and with the H55 in push/pull the fan presses against the video card's trim a bit. Seems fine, but instead of possibly causing issues that way i opted for the thicker rad where ill go push/pull on the bottom slot where i have room and just the push fan on the top and they wont have to push against eachother possibly causing issue if i ever move the case. I cant wait to get it and see what i can do if/when the mobo becomes the limiting factor. Too bad the only spot for it also means throwing all that heat at the rest of the components, but theres quite a bit of airflow in there otherwise too.

I have a question about overclocking using fsb speed instead/before adjusting multipliers. I heard some find better results with either method so I figured I'd try it out too. I know it changes NB, ram, and etc. But does it affect my video cards? So far I've reached where I have to start increasing voltages and have been doing so. I seem to be passing prime tests when voltage is adequate, but I also seem to have core temp and other program windows that seem to flicker slightly but otherwise be stable and trouble free. It's not bad or real obvious, just a quick flicker quick every now and then. Is this the video card getting affected, or maybe ram? I'm unfamiliar with what ram does when unstable other than crashing. Maybe I'm worrying about nothing, but I still need to know for sure if it affects the video card since I overclocked that previously to its max stable settings
