Trying to Overclock FX8350 (Problems)

[Aaronp]

Hello! Trying to overclock my FX8350 to 4.7/5GHz somewhere inbetween, Currently I'm at 1.425 Volts at 4.7GHz, its always been at 1.425 volts with the performance booster in the bios but only at 4.2 GHz so no problems, didnt even go near 1.425 Volts I would assume. I tried going up, testing, etc checking tempatures but when I was at 4.7Ghz and I stress tested with prime95 it went up to 84 (After the test it jumped up to 96 somehow according to HWMonitor, Averaging at around 35 normally so that shocked me too. later saying 192C... Im so confused right now lol) Degree C Max, was at a decent 68 for the majority of the test but than just jolted to 84 so I stopped the test ASAP of course. Im thinking that maybe my h100 is seated incorrectly orrrr I dont know. I'm running it with a Corsair h100 with 4 Corsair SP120 fans with GA-99FXA-UD7 Revision 1.1 MoBo, I somehow doubt the temperatures afterwards were correct but it did jump up to 84 I can garantee from the temps of the air coming out of the PC.I grabbed a picture before restarting but noticed that the max temps went up to 94 followed by 192, clearly the 192 was incorrect, I would assume the 94 as well ebcause it was running perfectly at the time.

AMD's temp sensors are garbage, you can't trust them. That doesn't mean that your chip isn't running hot I'm just saying take anything that's reported with a grain of salt.

It's not garbage, people are using monitoring tools that received their last update 10 years ago. Use something else like Coretemp

Seeing that your CPU is passing the Tjmax (91°) at 95°, thats not really possible.

Started using Core Temp but in Prime95 when it starts getting to test 3 it starts moving past 70C, Max reached 72 so I stopped it. Currently at 1.425 Volts 4.7GHz, though in Core Temp it isnt all over the place like it was in HWMonitor, Any thoughts?

72° in prime95 sounds normal for a 4.7GHz 8350 & H100. A H100 can't even do more than 4.6GHz on a 3930K and their power consumption is nearly the same although the 3930K is higher.

Went down to 1.40 Volts at 4.7GHz (There was one error) and after about 25-30 minutes Prime95 was at 74C which I do believe is too hot(?) so I'm going to do 1.375 at 4.6GHz. Thoughts? Would 4.7 be possible I wonder? Im checking out 4.6 now

If your chip can't do it it can't do it. You will just have to settle for lower clocks.

Those temps are offcourse not correct, but the older gigabyte AM3+ boards are garbage.

Also the amd temp sensors are indeed not allways accurate.

 

Did you had any stability issues with it? cause that mobo is not realy the most reliable

thats normal for an intel cpu its way too high for amd

amd chips arent suppose to go over 62c they should throttle at around 70-75c. try remounting your cooler as 1.4v isn't very high

I know but having such temperatures in something like prime is complety normal. Although he didnt really mention which SP120 he uses (quiet or high performance edition) but the quiet edition or any low rpm fan isn't just enough to keep a 8350 below 62° in prime95.

its not. it would be throttling at that speed if the sensor was working and the software was correct. with a h100 and an 8 core at that voltage i would be expecting the temps to be in the mid 50's under full artificial load.

I have the same board. Use ET6 and it will show you correct temps. Coretemp and HWMonitor are off by 10C. I tested this until thermal shut off to verify.

 

You using just the multi or FSB to OC?

 

I would reseat the H-100 like @Jumper118 said.

 

Also you will most likely need more then 1.425V under load to make 4.7Ghz stable. Use Very High or Extreme LLC(Depends on Voltage).

 

Those temps are offcourse not correct, but the older gigabyte AM3+ boards are garbage.

Did you had any stability issues with it? cause that mobo is not realy the most reliable

 

I use a UD7 rev 1.1 and have alot of the AMD Cinebench scores for LTT. 

 

Alot of the time the problem is between the keyboard and chair.

[Sintezza]

Lol your reaction is realy funny. The older revisions of all gigabyte am3+ boards, had alot of issues, especialy with overheating vrm´s mosfets, and northbridge chips. UD3 / UD5 and the UD7 also included. i have to say that, that theire newest revision's are alot better, and solved the thermal issues.

 

Those gigabyte boards cost me too much headaces in the past. for me personaly overclocking a FX 8 core on a highend mobo, i would go for the Asus crosshair V Formula Z or the Asrock 990FX Extreme 9. but even the semi highend Asus 990FX sabertooth is a rock sollid stable OC board.

 

But if op does not has any stability issues, then it seems that there is something wrong with his H100, does the pump even work? H100 pumps are also not the most reliable.

I would say trow the overclock away, and look what the temps do on stock.. If the temps on stock are getting that high aswell, then big chance that there is something wrong with your H100. At stock it shouldn´t be go much higher then 45 degrees on stress.
