8350 CPU Watercooled Overclocking Help

[Aaronp]

So I'm overclocking my FX 8350 processor from AMD but at 1.4Volts, with a Corsair h100, 4 fans in pushpull config. The Motherboard is a Gigabyte 990fxa-ud7, anyways when I go to overclock it it maxes out at 64 degrees with prime95 after about 7 hours, Its not consistently on 64 degrees, its around 59-62 degree's regularly in Prime95 blend mode, I just find that I should be able to do more voltage without that kind of heat with watercooling, Ive reseated the block 3 times so apparently thats not really the problem, any help? Not sure if these temps are normal or not but, they seem quite high. Im clocked at 4.7GHz which is nice and stable but I was thinking id be able to clock 5GHz with my cooler, Might try getting rid of the dust again incase theres another buildup but there shouldnt be any big buildups. Also when I try to go above 4.7GHz is freezes up even if I put the voltage up to 1.425, but either way its always been running this hot with the cooler so I question if something is wrong because i was told it should be running a lot cooler than it is, iv been told people can push 1.5v with an H100 so 1.425, or even 1.45 should be extremely easy. Sorry for my ranting, My head is a little out of it so dont mind if Im jumping all over the place haha (It runs idle at around 37 Degrees with 2 games running and a ton of tabs open in google chrome, so this clock is easily managle but not being able to go over is kind of strange I think)

 

 

EDIT:

Stop saying I'm killing my CPU, the the builtin overclocker overvolts from 1.375 to 1.425 and I'm at 1.4v. Lower than what AMD set by default, the average temperature while running a lot of intense programs,1  intense game and 1 not so intense game, I average 34 degrees. Only in Prime95 did I hit 64 degrees, but the average temp in prime95 is 60ish. And we all know Prime95 is a very very intense program that goes over the limit of what anyone would even do. So its a stable clock and under the voltage of what mostly everyone does with the FX8350.

1.4 v is VERY high. You're seriously reducing the life span of your CPU at this point...

Usually overclocks are mean to stay below 1.3v for normal daily use.

Your CPU core temp should not exceed 62 degrees when overclocked. You're pushing your chip too far.

[threadysparrow]

64 C is not that high for that level of overclocking IMO. Some might think otherwise but that's my opinion and I'm sticking to it. No level of dust cleaning is going to do a damned thing if there isn't a big ass dust bunny in there. Coolers are made to handle moderate levels of dust.

 

But like he said, you're killing your machine.

Not necissarily, the stock voltage for my FX8350 is 1.375 so it is definitely not very high, you dont seem to know a lot about the AMD FX8350... Haha and the reason I made this post is BECAUSE I want to fix the temperature, Im not stupid man Its not going above that at all, running for like 8-10 hours it hit 64 degrees for not very long with prime95, which isnt all the surprising... Of course its not the best so I came here to get some help on what could be the issue here because my h100 isnt doing as good as it should be, that or my CPU gets extremely hot, but getting 4.7GHz on 1.4v is quite good. Also the built in AMD Autoclocker for this chip sets the voltage at 1.425v, so I'm definitely not overdoing it on the voltage

Well I just removed a dust filter and it reduced the average temperature by 2-3 degrees, so Im thinking that maybe its might be being choked

[GloriousPain]

You're killing that CPU >.> you MONSTER. Also dude just give up you lost the silicon lottery get over it...

yeah cleaning it once might help, but you made it seem like you cleaned it a few times.

Oh I was assuming the stock voltage was 1v like on normal CPUs. My bad. Can you tell us your H100 pump RPM, fan speed, and what fans you're using?

Also I would suggest using some aftermarket thermal paste such as MX-4 to reduce temps even further.

In terms of heat, 1.4v is 1.4v whether using intel or AMD AFAIK. 62c is way low. I doubt those are your actual temps. I don't know if many people are going to know much on this since AMD CPU's are less common since they are simply worse.

Naw I dont really care if mines all that great, Just checking whats up, because the temps seem off too me. Just trying to get some more thoughts. the CPU isnt being killed because AMD's stock overclocker goes up to 1.425v bro, also it only gets that hot in Prime95 after 8ish hours of running, on average its around 59-60 during Prime95, running tons of stuff (the usual things I always have opened plus 1 intense game and another low end game) I have an average temp of 34 now. Its a stable overclock, I just wont be able to go any higher

Im pretty solid on Fans, using 4 of the Corsair SP's in pushpull. Gotta figure out if the fans are going at their full potential through the Cosair H100 controller on the waterblock. My thermal paste is aftermarket, I use the Arctic Silver 5

Depending on when you bought your CPU if it was after the release of the 9590 then it will have been binned lower to accommodate the higher OC of the new chips.

My CPU can run 4.6Ghz stable at stock volts at around 62C in prime 95, if I increase the voltage the temps jump to almost 70C and above.

I think you may have reached the limits of your CPU on your cooler.

Yeah okay thats what I was looking for Thanks man! I bought it when it released pretty much

OP

 

judging from the speeds you are achieving

 

i guess you have done the following

 

Disable APM, Spread spectrum, AMD Power App, Cool n Quiet, C6 state,

 

and Enable HPC

 

put the voltage near 1,46V~1.48v and the cpu multiplier to 24~25

 

Set CPU NB voltage to 1.25V

Are you speaking for the Gigabyte 990fxa series?

[dragoon20005]

kinda

 

but this is mostly for the 990FX chipset

 

and these are the settings i may use

 

but your mileage may vary

Yeah was just wondering if you had experience with these specific boards, Theyll most likely have different names. Ill have to look into it, thanks for the advice! Lets hope it helps I dont think im going to amp up the voltage though. 1.4 is very stable, Ill have to see as I go though

What Loadline Calibration do you have (LLC) if available in BIOS? On my Gigabyte AM3+ board it was under voltage settings.

 

Although some early revision 990FX boards don't seem to have LLC.

 

I generally find best results on the 2nd highest setting.

 

Also yes; people that are telling you you're killing your chip apparently don't have AMD CPU experience so disregard that these SOI chips can suck up 1.5v quite happily.

 

Also as dragoon mentioned try disable APM, Cool'n'quiet, C6, C1E, Turbo core(if you didn't already). Some people suggest turning HPC on, I didn't get any difference either way so I just leave it.

 

I found my 8320 could run nicely up to ~68c as long as socket temps were below 77c which was throttle point, so if your prime95 temp is 68 but in game temps are ~60 I'd consider it safe.

Mmk, Ill listen to you guys, Not going to go above an average of 61 degrees in prime95 though :PP Wanna get the best clock I can at the safest temperatures Thanks!

Remember colder ambients help You can sometimes drop a few c using the H100i as intake if you aren't already

or just like a car dyno

 

feed air using a desk fan towards the front of the PC

Yeah I was thinking of flipping the fans around because its currently blowing out, which is why I said it might be being suffocated, just not sure if it would help with temperatures

Have 2 spots on the bottom of the case for fans so I was thinking of putting 2 Corsair AF series fans to get my airflow into the case

as long as it's on wooden surface, i'd make sure all front/side vents are populated first, and try swapping the fans over for your cooler it could give you some headroom for more volts

yea you can try that but your CPU radiator is the crucial part

 

 

which is why the intercooler in a turbocharged car is installed in the front
