Overclocking Fx8350

[HindGB]

So I recently started overclocking my fx8350, and with stock voltage I could get it to just about 4.5GHz, Now I didn't stress test it for long (only about 25 mins), and it told me my cpu temps were around 55/60c with my H100i cooler (i get this is on 100% load so didn't think too much of it). Can anyone tell me if this is expected or is it higher than normal? I'm using HWMonitor for temps. I'd ideally like to try and stretch to around 4.6/4.7GHz on an overclock but I don't know if that's pushing it too hard, I normally run my H100i on quiet/mid power (max speed sounds like a helicopter taking off).

 

I'm also wary of the fact I haven't changed the stock thermal paste so there may be a number of reasons for these temps, I'd appreciate some suggestions,

Can anyone help?

Just don't pull a jayztwocents; if it's too hot it'll throttle itself.

Funnily enough I literally just watched that lol.

Heh

 

So my advice is to have fun but don't go over 1.45 volts, and if it throttles, reduce voltage a bit.

I've only actually increased the voltage from the stock level by 1 'iteration', I'm not at the PC in question since I'm at Uni so I can't remember the number of the iteration, something's telling me it was about 1.36, now from stock voltage to 4.5GHz I can't tell why my temps would be that high for 100% load, It keeps bugging me in the back of my mind that It might be something to do with the thermal paste or something.

Those temps are about on par with what I saw when putting synthetic load on my 8320@4.6GHz(Granted I had a custom loop on it with way more rad space). I was able to hit a 5.05GHz OC on my CPU so unless you lost the silicon lottery big time go for that 4.7. you wont see those kinds of temps in gaming anyways.

Because I'm pretty conservative I haven't actually OC'd to a level where the computer shuts down from throttling yet, is it a bad idea to OC until that point? It's just the level I stopped at the temps were just worrying me.

I got my FX8320 running at 4.76Ghz on 1.475V and it reaches temps about 58-60°C (I also got the Corsair H100i with 2 EK Vardar FF5). I hope this helps you a bit

Dont worry bout those temps man you good. 60C isnt bad at all with an AIO at the 4.5GHz OC

Pushing for 4.6/4.7Ghz on a MSI 970 gaming mobo is to much, what are your socket temps under stress test ? even at 4.5Ghz i recommend having a fan blowing over the VRM's, if you want to push for more, then replace the thermal pads for the VRM's and then add a fan, you shouldn't have issues then.

The only mobo temps I was seeing were about 50c, I'm guessing that was the socket temp. The VRMs have decent heatsinks and I have the back case fan sucking air into the case which is sort of blowing cool air over the mobo.

Hell i did 5.05 on it stable for months so dont even start with that

[HindGB]

I'll see about replacing the thermal paste as well as seeing how far I can push it with some more fans and different temp software, What would you guys suggest for the most accurate monitoring software?

[HindGB]

And also what would you guys suggest for a 'minimum safe' amount of time to stress test an OC for? (i use Aida64 atm), I'm strapped for time most days so I can't really be leaving it for 24hrs if I'm doing specific work.

I wouldn't go Push Pull on the Corsair H100i, you won't see a big difference, maybe 1 / 2°C

I'm only using pull atm, can't fit Push pull on the top of the Zalman Z11 plus, I'm just thinking about replacing the stock fans with something like corsair SP120s and the back fan an AF120.

[MadMurl0c]

The stock fans that come with the H100i can ramp up to 2700RPM so they are not that bad, maybe a bit loud if you turn them up but they should deliver relatively good cooling performance

For AIOs usually an hour is good to let the water temps settle down in your AIO, and HWMonitor is the one I use hands down.

My bad didnt even realize it. My board never had the thermal pad "leaking" issue and from what I see thank god it didnt. I also got a really good 8320 that didnt require to much extra voltage to hit that 5.05OC

Your temps are normal for that cooler and 1.36v at full synthetic stress tests. When you run the stress tests, monitor the actual vcore being delivered to the CPU (to know at which actual voltage it is stable, and decide whether you want to touch LLC or other settings).

Your clocks also seem reasonable for that voltage.

Unlikely if your package temps 55/60. The socket temp will be higher than the package (it's the temp reported as CPU by the motherboard or CPUTIN)

On the other hand, if 55/60 were socket temps, then the package temp is somewhere below that, which is good.

Having a rear intake can help the VRMs come a few degrees down, at least in my experience (I assume you have top exhausts, maybe the h100i itself). But doing what @Strike105X suggests can have a much higher impact on VRM temps - air doesn't circulate that well down there, but a little push goes a long way in improving the situation. It probably won't be too necessary until you push the OC further, though.

that has cleared some things up, thank you. 

 

When I get home I'll double check the socket and package temps and see what I can do.

Fx chips can go 1.5-1.55V some say as far as you want as long as you have the cooling a lot will push them to 1.6v or so and ran it with no problems for years. i have a fx 8320 on a msi 970 gaming mobo and my cpu is oc to 4.5ghz on 1.52-1.53v about with a hyper 212 evo. i dont suggest going over 1.5-1.55v and if you are going to do 1.6v would differnalty wanna go with a 990 chipset instead of a 970. Ive been running my 8320@4.5ghz on 1.52-1.53v for awhile now and have had any problems and if you only hit 70-80c for temps under full load you will be fine as very rarely will all 8 cores of the cpu will be pinned and if so most likely not for long. Also it should throttle its self if the temps are getting to high but keep an eye on temps for a month or two or when its hot in the room and if you are getting worried scale it back a little and the reason why you can get 4.5ghz with almost not touching the Vcore is because that is what that chip will boost up to so it dosnt take to much more power to get to that point. i remeber overlocking mine it took nothing to get to 4Ghz but to push it up to 4.5Ghz i had to add some volts. just be careful and keep an eye on temps and dont push to many volts into it that board dosnt have LLC(line load calabration) so it is giving the cpu less volts then what is stated. you would have to get a multimeter out to find out the vdrop and stuff and it shouldnt be a lot but there is a little and jay burned his fx 8350 because he didnt clear cmos before he reboot because his mobo complety shuts off and he explained it in the video. also he notcied the Vcore was incressing above what he set it to and that is what was causing him to get worried about it and then he messed up when he reboot it but that mobo shouldnt give more then the volts you have it set to as there is no LLC and what not. also you can try overclocking the fbs but you have to deal with ram and all that stuff then but if you are looking for them extra few %'s. gernally to get the highest oc its a combaintion of both. good luck tho hope some of it helpped as i was looking into the Fx chip max voltages awhile back.

damn win the lottery lol.. i think i lost on my fx 8320 feelsbadman. you stress tested that as well?

Speaking of I think my 8320 was the highest forum cinebench score on water, only being beaten out by LN2 cooling solutions haha. I still have it lying around somewhere. Wonder if I could push it farther with a better motherboard.

Haha nice. Wish mine was better lol..also wish my gtx 780 power delivery didn't go out on it. Stuck with a 560ti feelsbadman.

thats the fastest i was able to get on air, i down clocked it though to 4.5ghz @1.4v a while back, i was getting some thermal throttling in long gaming sessions 6+hours unless i had a fan over the VRMs
