For 1.33v on the Vcore, 52C on the core isn't too bad of a temperature, although it is a bummer that you top out at 4.0ghz. You still have some thermal headroom, according to the CPU core - however, your CPU socket is about as high as you want to let it be. (CPU socket and CPU core, while related, are not quite the same.)
I am unsure of how well the Deepcool Maelstrom 120k is. 120mm AIO coolers take something special to be anything decent, it could very well be that, like you ( @jackal7618 ) said, it isn't very good at all. The Evo is a fairly stalwart entry level cooler. It has managed to get some people up to 4.4ghz, but that is if you get decent with the lottery and have decent ambient temperatures.
Anyway, keep us informed with how it goes! Saw your sister-post on Tom's Hardware!
depends a bit on the budget you have for a cooler. buying a new cpu and a new cooler all together doesnt make much sense to me to be honnest. Not sure if you have build this for overclocking, or that overclocking is one of the main things you like to do. Because honnestly in terms of gaming performance, even a locked i5 beats it.
Hey everyone back to update! So I went to the store and exchanged my old 8320e for a new one I told them I was having thermal issues with it. I also picked up a Deepcool Lucifer v2 after seeing such great reviews for it. I spent like 4 hours installing it, As I didn't want to completely remove my mobo, so I applied the thermal paste via the middle dot method I had a very hard time adjusting the new cooler wheres I had to take it off(with effort it was stuck at times by the thermal paste.) turn it, take it off, turn it for 4 hours hopefully my thermal paste is okay it did spread during this (I do not want to go back there for awhile.) I got it fitted with some brute strength holding the heat sink down sigh..because of the fittings doing a see-saw thing, lol.
Alright guys, I just saw this discussion and read through all of it. I have an FX-8320 CPU and Asus M5A97 r2.0 motherboard and have the same problem with OC as jackal. I'm currently running a stable 3.9GHz OC but it seems like anything higher than that like 4.0 makes it freeze shortly after bootup. I have Noctua NH-D14 cooler and Fractal Design Core 3000 case so I don't think that cooling is a problem here. I think it might be the LLC stuff... And I'm not really into it. What is LLC? And I've always been putting it off and here someone said it should be on so I'm kinda confused. I also turned off all power saving features. BIOS version is 2603.
LLC stands for Load-Line Calibration, it is used to combat what is called "vdroop". When you set your voltage to, say, 1.35v, but it drops down to 1.29v when under load, that is vdroop.
This happens because the transfer of energy is never perfect, and there is often waste - which takes place in the form of heat.
Load-line Calibration adds additional voltage when the CPU is under load, to help fight vdroop.
The Asus M5A97 R2.0 has a 4+2 phase Voltage Regulator Module - it's not the most robust. Depending on how much voltage you are shoving through it, you may have already hit your limit.
Yeah... The voltage under load is 1.368V on 4 GHz and it's not stable. I guess it's the board then :/ I tried with LLC on too, but nope. Strangely though, when I boot it like that at 4GHz and run CPU CineBench benchmark, it runs fine, but it freezes immediately when I start OpenGL benchmark?? Could it be something with the GPU maybe?
And if my 8320 can't run at 4GHz, does that mean that an 8350 on the same board wouldn't even run at stock? Because it's the same chip but overclocked right?
Quite potentially, but it would depend on how much voltage it requires to run at stock. I've been told that stock voltage is 1.4v, but I have heard others say otherwise about their individual CPU.
Your case and airflow should be fairly decent. What is the ambient temperature? (Do you have a spare fan to try to put over the VRM?)
You cant expect much from the FX8320(E) as its a gimped low bined chip sold as a 'low power' chip running at 95w instead of 125w that a standard FX8320 or FX 8350 runs at.
Current ambient temperature is 26 degrees Celsius. I do have a spare 120mm fan, but the Noctua cooler is in the way so I don't think it's going to be possible... But doesn't my board have a decent VRM passive cooling?
I haven't tried undervolting yet. I will try now. I'm confused about my stock voltage because UEFI doesn't always show the same value, but when I load optimized defaults it says 1.32V. Is that possible? And also, what is CPU/PCI-E Spread Spectrum?
So many questions from me guys, but thank you for answering, I am actually learning new stuff. :)
Okay what the heck my CPU is now stable at 4GHz under load. Voltage is oscillating between 1.272 - 1.296V. Temperature is too high in my opinion tho... Reaches 55 degrees in OCCT after 10 minutes.
But I think my problem was in giving the board too much voltage so it was crashing because it couldn't handle it.
55c is actualy a cool cpu for a AMD octa core. Never mess will LLC on a cheaper asus mobo allways set it to automatic or it just send's way to much voltage to the chip my ASUS M5A97 R2 EVO just cooked with LLC enabled on anything else than automatic and the northbridge was so hot it burned the skin to touch.
The M5A97 R2.0 does have heatsinks for the VRM, but the fewer amount of phases for the VRM means that each segment of the VRM has to handle that much more energy, and therefore runs that much hotter.
Thank you very much :) I understand what I was doing wrong now... I'm going to mess around with it a little more and maybe post my best results later. :D
