FX 8320 on Asus M5A97 R2.0 locking up - Page 2

post #11 of 27
Thread Starter 
Alright guys, I tried out your advices with increasing the voltage. I bumped it up on NB, RAM and CPU more than usual. I was leaving the voltage setting on NB and RAM on "Auto" before. Now the problem seems to be solved. System is extremely stable even under heavy 100% load using OCCT for 15 minutes and with 3 tabs (including youtube videos) in Firefox opened. Before it would lock-up under a minute in OCCT. I think it could be NB, but will continue testing later. The PSU isn't the problem. smile.gif

Thanks guys so much for help, I would never think of increasing NB voltage because I always thought that "Auto" was giving it enough juice... Doesn't seem like it.

Also, can someone explain to me what LLC is actually for? Is it better to leave it on enabled or disabled? Or Auto? Those are the only 3 settings I have for it. Tnx wink.gif

Cheers! thumb.gif

Great to hear it's resolved. Sometimes there isn't enough voltage on the NB for the memory controller on the chip. The CPU does need to talk to the RAM thumb.gif
LLC (Load Line Calibration) is a way to prevent VDroop. When put under stress, the voltage changes. Sometimes it can spike wildly (not too dangerously as long as it isn't above recommendations) and can cause a lockup. When the chip needs more volts than what it is getting and cannot get enough fast enough - lockup. LLC keeps the volts higher; close to what will be needed when under load. This does result in loss of efficiency and higher temps... but this is OCN devil.gif

It is smile.gif
I also noticed that when I raised what was needed the PC became noticeably faster. I mean, when I had it on 4.2 without increased NB voltage, windows was loading quite slower than now. That's also a nice change smile.gif
I usually leave the LLC on disabled and put the voltage on something that will always be enough for the CPU to work. I'd like to try pushing it to 4.5 cause I can with my cooling, but not sure if mobo will allow it. biggrin.gif

I immediately know I have a bad OC when Windows takes an additional 15 seconds to let me enter my password. It's not guaranteed that it is a bad overclock, but most of the time it is. Right now I have my 8350 on my Sabertooth at 22x 200 with 1.3875v. I can do 22.5x for a 4.5GHz OC with 1.3925v, but I do put all my cores under stress in daily situations, so temperatures are an issue. I did just clean my H100 vent and the fan filters on my case, so I think I'm good at 4.4GHz for a little bit

That's great! smile.gif
I didn't know that unstable OC could slow down the system. Also, what power saving features can I leave enabled? Currently they are all disabled. What's APM? Or Application Master Mode it says?

Well, unfortunately the problem isn't solved. Just came back from school, turned on the PC and after about half an hour locked up on a youtube video... Same settings as yesterday when I thought I solved it. frown.gif

I'm starting to suspect the 4+2 VRM. I don't want to discourage you, but if applying more volts to NB, RAM, and CPU didn't give stability, then the last option is to turn on LLC and pray for the best. Good luck

The LLC is turned on... :/
There is one other thing I'm afraid of... I made a huge mistake about a month and a half ago, but I didn't think about it at all till now. I tried to update my BIOS through USB BIOS Flashback and it didn't work. The light didn't flash as intended and the system didn't boot. Then I started fraking out but found a way out and downgraded the BIOS to version 15xx I believe. It's now on v1903. Funny thing is, when I got the PC in August and Oc'ed it to 4.4GHz everything worked fine. But after this bios thing it started happening...
It' not possible that 4+2VRM can't reach 4GHz because almost 100% chips do reach at least 4.2, so I'm really not suspicious about the VRM.
What do you think?

I've been following a few threads dealing with overclocking problems, so I got yours mixed up with another, my mistake. I thought you were going for a higher overclock. I would reset your BIOS/CMOS and re flash it just to be sure. The ASUS easy flash is actually really easy to use, so it shouldn't be an issue.

Alright, so should I flash it with the latest version?
