SO CLOSE! Stability issues on FX8320 at 4.6Ghz

[fueloficarus]

Hey there, does anyone have any idea why I wouldn't be able to reach 4.6ghz on an FX 8320? My rigs in my signature, and I've seen plenty of posts from other people reaching it with a single 140 radiator i80. Could it be my motherboard being a 970? Or RAM (considering trading or selling my PNY stick and keeping my HyperX)? Or should I be modifying the BUS frequency instead of the multiplier? I was pushing 1.456 CPU voltage, and could open Windows, but would crash right quick. I made it into prime95, but didn't even get to see the test start. I tried it with one stick of RAM (even though I have different brands the latency and timing are the same) to no avail.

OS: Windows 10 Pro | CPU: AMD FX-8320 3.5ghz (OCd to 4.2) | Corsair H100i V2
Water Cooler | GPU: MSI Radeon RX480 8GB | PSU: Corsair 750W Modular | Mobo: ASUS 970
Aura | 16GB DDR3RAM | WD Blue 1TB HD, SSD, Sandisk 240GB SSD

As I posted in your other thread; mixing ram is not advised unless they have the same exact timings/sub timings and voltages.

What are the timings for:

PNY

HyperX

?

About to run memtest to confirm. Each are different. I can manually set the timings to help even that out, right?

 

[Mr.Scott]

More vcore. Your chips a ****ty clocker, and what are your load temps?

More voltage? Hmm...okay. Not much, just about 45 under load at 4.4Ghz.

O my god what're you waiting for?. Juice it up a little. You still got cooling room.

And the mobo may be a limiting factor. As you go farther up the scale octo core FX chips get hungry. There aren't a lot of boards that can reliably run big OC on them.

 

[Mr.Scott]

That 970 Aura is a top 5 board easy. It'll be just fine.

[Mr.Scott]

Run 11-11-11-x @ 1.5v

And you're gonna need to do something about that shanker on your finger pretty soon.

 

[Alaric]

Missed that the first time. I should have looked a little closer. My bad. I just came to this thread from the OP's thead asking about temps. Definitely some headroom there.

Believe it or not that's a scar! Looks like a wart, eh? I took a nail to the finger from a nail gun in the hand of an idiot friend.

Looks like Mr. Scott & Alaric got you covered. You're in good hands.

 

[Mr.Scott]

HPC mode should be enabled.

Thanks for the help! Have a nice evening, good sir.

Do you think that's contributing? I don't really understand what Disabling/Enabling High Powered Computing mode entails. Forgive my ignorance. When I last was doing any real overclocking we were building resistors to do it, and BIOS was about five options.

...I'm not that old, but I did it whilst very young. That sounds legit, eh?

 

[Mr.Scott]

Could be a factor. It's not gonna hurt.

HPC Mode (High Performance Computing) - HPC Mode is a setting in the BIOS that prevents the CPU from lowering and locking its clock rate under load in certain conditions. In some benchmarks, HPC Mode can increase performance by about 6%, but these performance improvements are only realized in benchmarks like HPL. Dell tested this setting for the AMD Interlagos Server based CPU'sand saw very little performance increase outside of HPL benchmarks. HPC Mode did however increase power consumption and power draw for very little benefit.

In a nutshell, HPC Mode prevents the CPU from locking and lowering its clock rate when the chip is either getting close to going over the TDP, or the motherboard CPU socket temp is getting to high. This is not always true in all cases though, because in certain situations, the CPU can still drop and lock its clock rate under load. This setting is more geared to very specific environments such as clustered computing where there are specific applications running that would benefit from this setting. Those situations are not your average home user.

I understand. I'm 'not that old' either.......even when I was soldering crystals to gain 15 MHz.

 

[fueloficarus]

Oh ****! Brother's droppin' hot crystals! You just made my night, good sir. Concerning the RAM...HyperX Fury automatically overclocks to 1866...this might be my issue here. PNY has a 9-9-9-27 CAS timing right on the label. HyperX is programmable up to 11. Will setting it to 9 force both chipsets to that latency?

And I'm going to lurk in the corner, because Mr. Scott is one of the guys I'd be asking about this.

Hah! I'm researching as I'm going, here. I could probably yank that PNY, I doubt it would affect my performance much, even in TF2 and BF1.

 

[fueloficarus]

Ah, well...now after about 40 minutes of prime95 I have CPU throttling. But my temps are at about 48. This just keeps getting better and better.
