FX 8350 4.4ghz OC - GA 970-UD3P - Page 4

post #31 of 40
Thread Starter 
Tried 4.4Ghz with vcore voltage on "Normal" instead of "Auto" and by enabling the dynamic core as you said to "0.00000".
The value "0.000000" lets me think it drains all the additional voltage it needs for stable frequency, but I am not sure.

Tested it with occt and it actually reached 1.44 vcore under load (This didn't happen with voltage on auto), unfortunatly temps raised up to 61°C after 3 minutes, so I shut down the test because that was getting dangerous.

Do you think I can keep this state? or I need to have it stable on occt?
I don't games will stress the cpu as much occt does.

So your getting the extra volts even though dynamic is at 0.0? With it at 0 I figured it would run stock volts until you added onto it and I'm sorry if I confused you, your supposed to add volts with the dynamic setting
, when I'd use it I would just increase by 0.025v and then test, the 0.025v should give you that much to your cpu from stock volts, but then you have to compensate for llc.
So if my guessimation is right if you put 0.12v on it should give you around 1.44v, but I do NOT suggest just throwing it In and booting up, if you haven't already, mark the volts required for every 0.1 oc from stock and write it down so you can go back to it, this way you can later tell if the extra volts is worth a 0.1 increase compared to the previous 0.1,not only that you may not need the whole 1.44v for 4.4.

Also temp wise, after you do a run or two of occt or prime do exactly what you normally do, play games,movies, etc and see how temps compare.

In my experience most games run 10c under what I get in prime95 (after the 20 mark when it really heats up)
I get temps up to 65c when at 4.5 in prime but I stay under 55c when playing bf4 64p after a few hours of nonstop gaming.
It'll be rare to get up to the same temps as prime or occt when doing regular stuff

Also were you able to increase your clocks off of stock and not increase voltage at al while being stable? Just curious tongue.gif

I was able to overclock up to 4.2Ghz stable (turbo off) with stock voltage, without changing any more settings, if I go 4.3 occt gives me error after 3 minutes.
But I tried to set Load Line Calibration LLC to EXTREME, and the dynamic core on 0.0000 .
I don't know which one of these settings allowed the vcore to go up to 1.4 underload without changing the voltage.

I think more than dynamic core it's the LLC which gave me that.
So according to this I could oc up to 4.4 Ghz on stock voltage without adding any values, because it gets up to 1.4vcore underload, enough for 4.4Ghz. (With LLC extreme enabled I think)
The only problems are the temps, after 5 mins on occt I saw 60°C on the cores and I shut the test off.

I noticed extreme llc on this board wasnt good, llc is supposed to lower the drop when under load like when you put in 1.4vbut only get 1.375v but with extreme for me, it increased the voltage used by a whole 0.1 and it would crash my pc in 10 min so yea it was prolly the llc giving you the volts when dynamic is at 0.
I'm honestly not sure how effective or safe using the llc only is, I don't know the ins and outs of llc and still don't fully understand how it works even though I've had more then one person explain it to me and read guides.

And cool about the 4.2, start increasing the dynamic by about 0.02v each test and see what you need for 4.3 until stable thumb.gif then 4.4!

Will do!
Will post results soon.

Thanks:D

If 4.4ghz requires 1.4-1.45 vcore, should I set dynamic core to a whole + 0.1?
stock vcore is 1.3375v

It'll roughly be 0.1 for 1.44v depending on llc setting I know for me on normal I get about a 0.030v drop from what I set in bios so it may be 0.120v.

If you want to see the differences of setting go back to a stable setting then start up with each setting and check for voltage changed, as you found out extreme adds to your max voltage quite a bit

I'd suggest auto or normal unless you test each setting and see if one is better for ya

@4.4 GHZ OVERCLOCK ACHIEVED! thumb.gif

I added 2 more fans to the case, one blowing air in front of the cpu, an other one on the side. For a total of 4 case fans, providing good air flow in the case in strategic positions.
Dynamic VCoore set to 0.1.(1.42v underload). Ran OCCT for one hour, no errors, max temp around 56°C.

Thank you for your help and patience wink.gif

woot! Thats great!! thumb.gif now go test some games, maybe a little prime as well, Ive found you can pass one test with flying colors and fail another one in 10 min, does it mean that its not stable, not exactly but it just means that it hangs up somewhere, may need extra voltage for those extra intensive situations

what were you temps before adding the fans?


temps can play a big role in OC's, Ive been told some cpus have harder times keeping an oc stable at higher then normal temps and the VRMs next to the CPU, if the VRMs get too hot it can cause throttling even when everything else like CnQ is disabled, I've been told countless times to put a fan that will blow air onto them, but I bought the ud3P because it had the heatsink, the Ud3 doesn't have one at all which were the people that NEEDED a fan on those. @.@
Im sure it wouldn't hurt but its a very VERY snug fit for an 80mm fan where I need it with very little options of mounting. tongue.gif

Yeah, indeed! thumb.gif

Temps before additional fans installation could reach 61°C in OCCT under load ( not really safe ), now I got like 5-6°C less.
In OCCT i get 55-56°C under load now.

I get about 45-46°C while playing BF4 multiplayer on ultra settings.

This is my fans set up:

plus an other fan on the side panel blowing air in. all fans are 1200rpm (not much, but do the job nicely)

Will run some games now and see how it goes.

Nice! remember you should have some temp headroom outside of prime/occt testing, obviously those programs give off more heat compared to bf4 or any other game, but I think your at a good spot temp and voltage wise, you could prolly do 4.5 and still not have a problem.

Have you noticed any performance differences? it may not be as obvious in some games as it could be in bf4 because bf4 will use all 8 cores therefor getting more mhz out of the oc, but you may notice your min fps go up a few, maybe only in certain situations.

with my 8320 I see about 4-10fps difference in my minimum fps when playing bf4 from 3.5 to 4.0
but I know with my 965be I got pretty much no increase when OCing
