FX 6300 overclock on stock voltages. - Page 6

post #51 of 61
I do 4.5 Ghz w/ 1.35v. After that the increases in voltage/heat out weigh the performance gain.

VRM throttle on a sub par mobo I'd bet.

yes my "sub par" mobo was part of my budget, buying a computer I could afford.
m5a78l-m lx plus, its like a 3 or 4 phase 53-55$ mobo

I wasn't trying to insult your budget. I was making an educated guess based upon the information I observed as I have extensive overclocking experience with FX's on motherboard's of all different VRM configs. FX is very picky when it comes to VRM's and overclocking, the more the merrier.

so, the mobo that I have, is it limiting my OC abilities? I've heard all kinds of things about the "throttling" or "drops" or "fluctuations" ranging from thats not normal, change settings in your BIOS, to that's normal, it's just your CPU because it never really stops working, to heat issues (which it's staying at 58c under 100% load, so I'm pretty sure that's not it. And it's not just random, it's multiple posts on all three + suggestions... so I'm not sure what to think.

A general rule of thumb is throttling within max core temp for CPU is due to either BIOS settings for power savings or VRM over heating on lower end boards. So in that case I would say yes because an OC that throttles is not a stable OC in my opinion. I will give you an example from my early encounter overclocking FX chips. My first board was a cheap MSI with 4+1 VRM that would not pass 4.2 Ghz w/ 1.38v. Core temps were in line but vrm's would throttle under load. I tried gigabyte and asrock 4+1 variants with relatively the same results. I moved up to a 990FX Asus board w/ a 6+2 Digital VRM and big fat heat sinks and bang 4.5Ghz w/ 1.36v 50c max temps and never throttles. Think of motherboards like performance cars. Can you make a civic try and be fast, sure. But at that point will it be an unstable piece of crap that at the end of the day still isn't as fast as a car that was actually meant to be fast and runs without issue, yes it will be that unstable POS. Overclocking takes specifically designed hardware, especially with FX. You want to go fast you need the right hardware.

Damn, it doesn't blue screen or die on me under stress or anything (Prime95) but because of the throttling I'm assuming that it's not getting the full use of the CPU? What does it mean performance wise if it throttles? (I'll be testing the throttling in Crysis 2 after the dang download is finished)

Yeah, its not recommended for 125 watt processors or overclocking.
http://www.overclock.net/t/946407/amd-motherboards-vrm-info-database/0_20

But you can try any way, you may have 30watts of headroom with the FX6300. biggrin.gif

Youll need to put a fan on the vrms, which are to the left of your cpu socket.
Make sure Turbo is turned off,
HPC mode is enabled, and
APM master mode is disabled.

Besides CnQ, C1E, and C6 disabled while testing overclocks.

I'm not familiar with APM master mode? Could you shoot me a quick how-to plz

It is hard to say if it is completely stable as the throttling will reduce the clockspeed and therefor the over all load on the CPU. What throttling translates to performance wise is FPS drops and over all sluggishness and lower performance when running any type of program (game or otherwise) that is CPU dependent.

As for APM master mode it is another feature that works hand in hand with cool and quiet to limit clocks and voltages here is all the in depth detail about the FX you will need. Read up.
