Some questions about OCing FX 8350
Some questions about OCing FX 8350
I suppose you are all already tired of answering the same qs over and over again but since im noob at OCing I wanted to make sure im doing the right thing.
So to the point, im trying to oc my cpu on gigabyte 990fxa ud3 rev 4.0 mbo. So far i have not reached a stable OC of 4.4 ghz or above (prime crashes after and hour and 20 min more or less). My cooler is Evo 212 and i read that it can cool the cpu to up to 4.5 which is my goal. So the solution would be to up the cpu voltage which is by default sitting at 1.284xx i think. Raising the voltage to 1.29 or 1.30 gives me the temps im not sure i should run it with. The temp goes as high as 60 Cs on Core, 59 on tempin2 and 59 on package temp monitored with speed fan and hw monitor. The cpu starts to downcloack to 1.5 ghz as soon as it reaches 60. Think package temp is socket (?) but not sure.
So my first q is can i leave the cpu to run on 60 C and see if itll fail the test? (i read somewhere that 62 is the max temp for fx 8350 so im kinda afraid to leave it there while the hw monitor and speed fan shows "code red". Ran prime on those voltages for about an hour then i stopped it. Didnt want to risk it without asking first.
Second im running rev 4 F2 version of the BIOS, there is a newer version F3 that has "updated AGESA or AEGESA code" or some such. Really dont know what that is so my q is pretty simple, should i flash my BIOS or not, i dont have any problems with the current version on stock speeds?
Thirdly im using a combination of both multiplier and fsb to reach 4.5 at first, now 4.4 ghz but both failed so my q is did i misunderstand that both fsb and multi yields better performance and better "stability" and should i try it with just multi or just fsb to try and reach better stability without upping the voltage that much?
4th should i or shouldnt i touch the nb freq which is by default 2200 when i change fsb or multi, or can i leave both nb freq and ht link (2600) on auto and just check if they are near defaults like with memory? Memory goes up from 1600 to 1700ish.
5th cpu unlock option on my bios, read it that its something about hidden cores, didnt understand that properly so if anyone can tell me should i leave this on disable or enable it? Tried both but prime crashed with both options so right now im thinking it doesnt matter.
Well since this is my first OCing i hope my qs are answered since it would help me to better understand the process and hopefully reach at least 4.4 ghz without too much voltage. (i should probably reapply thermal paste since well it could be i didnt apply it properly (too much or too little) the first time, but uh dont have time for that right now.
Apologies if i used the wrong technical term somewhere, as i stated im a newbie at this.
So I downloaded AIDA64 Extreme and now understand my CPU temperatures. I adjusted BIOS settings like voltages, core voltage loadline calibration, and calibrated the rest of my QS. It looks like I’ve reached a stable OC at 4.5 GHz with a core temp of 55°C and a north bridge temp of 54°C (as shown by AIDA). So far, 12 hours of continuous use with no errors, still running. I’m planning to run 3D Mark next.
I had to set VLLC to medium so my voltages are between -0.01 and -0.015 compared to the manual settings. If I set it at extreme, I get +0.06 and more voltage spikes, causing temperatures over 60°C in a second.
But now I have two questions that need answers to keep going with my OC. First, during the stress test, cores sometimes dropped to 1.5 GHz under full load but kept the same voltage and temperature at the lower setting (around 53°C to 55°C). I read that FX8350 downthrottles at 62, which is 7 degrees below that. Is this normal? I don’t see any errors in Prime or Warranties.
Second, since I can only set VLLC to medium (or idle, idle under load, but still within the range I set), can I be sure that 7°C is sufficient if the chip decides to pull down that 0.010 voltage? Or should I test the OC with a higher voltage to see if it can handle it?
Just execute the toughest SW you could possibly use, and don’t stress over torture tests. Use them only when SW/games are failing. Many users waste time torturing their computers, only to see them crash anyway!!!
I'll try Intel. However, the AIDA failure wasn't CPU-related, the FSR ran without issues. I didn't adjust the RAM multiplier enough. I fixed that now and will ask about the RAM OC later. But currently I'm still dealing with FSR testing—I don't want to see 1500 MHz on any test, not even after an hour.
P.s. currently I'm working hard with temperatures at 50, but I still think I could go higher since the passes are great for high speeds.
I just follow the preset. It still feels like it's near 100%. I let it run through 10 passes; if it stays stable at that level, you should be fine. Staying under 50% under full load isn't too bad. Just avoid letting it go past 60 for too long.
