FX8350 Temps.

[marco]

Hi, Temps for my fx8350 seem to high and fluctuating when overclocked, when setup defaults in bios are loaded temps are fine at 25 - 35 degrees but still fluctuate a little, here is a link to show what cooler I have > https://www.overclockers.co.uk/showproduct.php?prodid=HS-005-AN problem is when I overclock to 4.7ghz, idle temps shift between 57 - 75 degrees, so something is wrong with the overclock ? Is it to do with voltage ? Im a bit green when it comes to voltage may need help.
Here are some pics to show my bios settings:

what volts are you putting through the cpu? it just says auto in the pic.

how do I find that out ?

 

[WYP]

use programs called cpu-z and hardware monitor (HWMonitor).
i assume your new to overclocking?

we'll also need to know your cpu cooler and motherboard.

firstly please set everything back to stock settings please!
on auto god knows what voltage your using, 4.7 is a hefty overclock

ok cpu-z says 1.488 v and my mobo is stated in one of the bios pics (up the top), also a link to my cooler is in op.

oh yeah, sorry for missing that, multitasking is a B*&"£.

first thing for overclocking never keep it on auto volts, it will use too much volts and won't be stable.
second your motherboard is a lower end board, its not designed for overclocking. i'd advise reverting to stock immediately to avoid any damage to your board, those volts could kill the board if left like that.

if you want to overclock buy a higher end board, my gigabyte 990FXA-UD3 is awesome for amd stuff! otherwise i'd stick to stock settings.
you cooler is good enough for moderate overclocks on amd but without the motherboard to back it up please don't. i've seen people blow lower end motherboards with a lower volts and less power hungry cpu's

Message understood, back to stock, thanks for the help.

no problem, we are all here to help .

I'm runnig 4.4 Ghz on 1.375v. You can take a look at that. Also keep in mind this CPU does not like anything above 65C

There doesn't seem to be any direct way of changing the voltage with my board, but anyhow I've ordered a new mobo and its coming tomorrow, its this one > http://www.overclockers.co.uk/showproduct.php?prodid=MB-349-GI&groupid=701&catid=1903&subcat=2046 I will re-install windows upon installing new mobo and post back for some help.

 

[marco]

Ok, I now have installed a Gigabyte GA-990XA-UD3 mobo, this one > http://www.overclockers.co.uk/showproduct.php?prodid=MB-349-GI&groupid=701&catid=1903&subcat=2046 .

Although I have checked out tutorials they all seem to be for ASUS boards and the bios menus seem to be a little different. And as always the mobo manual is as vague as a blank bit of paper.

I've tinkered with the cpu ratio but not the voltage as im a little green in that area, everything is stock at the moment, would like to get my 8350 stable to 4.5 or more if I can but will need help, I have posted some pics of my bios showing the relevant menus, thanks in advance.
Main menu

CPU info etc

CPU setting

CPU features

Voltage control ?

 

[WYP]

Firstly watch this video!


It may be a intel 1155 overclocking video but the same principles apply to amd overclocking.

 

[marco]

Ok thanks, I watched the video a few times, my menus where almost the same, I used occt and cpu-z as stated in the vid, I followed the advise by undervolting first etc, tested @4.4ghz with stock volts ok, then 4.5 and 4.6 with stock volts also, (which was strange) but im now at 4.8 with +0.025 volts which is 1.428, (1.404 was stock) Then something puzzling happened, I noticed that whilst running occt, cpu-z showed the clock speed dropping to 3.4 ghz and volts drop to 1.4 when the temps got to about 73 degrees, is this settings in occt ? or my rig ? When I stopped occt they went back to 4.8. I made sure all of the cpu features where disabled in bios.

you dont really want it going past 70c really mate

 

[marco]

you dont really want it going past 70c really mate

could be that then, the screen did go a bit jittery, so I dropped it down to 4.7 for now, will test more and post back tomorrow.

 

[Wraith]

The voltage and frequency drop your seeing when you hit 73c is the AMD thermal fail safe preventing damage to the die. Perfectly normal

I don't know about the FX8350 but my 4100 had a -15c offset on the thermal readings in CPU-Z and Open Hardware Monitor as these software monitors don't read the AMD chips right, that in mind your true temp would be 88c and not 73c (just a thought)

 

[WYP]

i agree with Tripp on this, i wouldn't go over 70 degrees.

what cooler do you have on your cpu?

Antec Kulher h20 620, by no means the best but still very good, idle temps are between 35 and 42.

I've just run occt again at 4.7ghz with the +0.025 volts (1.404 is stock) so now its 1.428-ish, I experienced the core and volt drop again but this time temps where only 57 degrees (unless the screen froze, I don't know ?)

One of the guys on overclock.net had a throttling problem with the Gigabyte 990FXA-UD3 board. In his case the board was warped and the VRMs weren't making proper contact with the heatsink, thus the system would throttle even when the CPU was at perfectly reasonable temperatures. That's hardly your issue is it? Do you get throttling at stock?

It's buried somewhere in this thread:
http://www.overclock.net/t/1023100/official-gigabyte-ga-990fxa-series-owners-thread-club/6950

BTW, this is what I get for my FX-8350 at stock with an undervolt of 150mV.

Throttling at stock ? if you mean the core and volt drop then the answer would be no, stock runs sublime.
Basically what's happening is im running occt with cpu-z with my cpu at 4.7 or above with a slight voltage increase, and it runs ok for a minute or two then the core and volts will suddenly drop, I have turned all cpu features off in bios and set load line calibration and ram as advised in the video watsyerproblem posted,. It may just be a fail safe of sorts to prevent damage, but still, have I not turned off all that type of crap in the bios ?
