FX overclocking

[CyberWarrior]

Hello, are these good settings for my OC - AMD FX 8300 with multiplier (OC to 4.0 Ghz) and M5A97 EVO R2.0.

- Disable turbo

- Power saving settings (all restored after OC was stable):

- LCC left to auto because small change in voltage

- Manual - CPU Core 1.236 V idle - 1270 V in load

Are these setting okay?

 

Second, where is the best to put 80mm (?) in case? To blow on the socket, on the VRM or behind motherboard (probbably not a option because I have Define R5, no space behind)?

Seems a fine result, it's more or less 8350 voltage for 8350 speed. If you mean using an 80mm fan as a spot fan, place it near the VRMs, or VRMs - North Bridge if you cannot accommodate it fully on teh VRMs, as those are the parts of the motherboard that will get hotter in general and when OCing in particular.

On all my AMD's I've only ever just used the Multiplier.My old 1100T was at 4.0ghz for years.

my 8350"

So one fan to blow little on VRM, little on NB. How lower temp on socket can I expect?

Not sure, it will depend on how much the VRMs were affecting the temps right now. I'd say from negligible to 5C are the two extremes. My experience comes from a different board and a higher overclock, and my socket temps dropped 2-5 degrees, depending on the test, while the VRMs themselves went from 90s to 70s. The difference between core temps and socket temps narrowed.

I want to cool the socket. Is it better than to aim with a fan to VRm or directly to socket?

The socket is the least of your worries. These FX8xxx chips fry VRM's like no tomorrow without direct airflow, so focus on that instead

 

What cooler are you using by the way? A top down cooler is preferred in a setup like this. If you go AIO or custom loop, you'll need to add a fan to blow directly on the VRM heatsinks.

I use CM TPC 600. Difference between my socket temp and core temp is 16C~ in load. Fan behind motherboard is not an option, so I will put the fan on VRM. Do you now how to mount it?

that's a small OC, VRM cooling is probably not necessary.

The FX9XXX series are tough on VRM's,Not the 8XXX's.And considering how cheap the AMD boards are, I wouldn't use less than a 990FX board for OC'ing.

Well  I can tell you that the chipset doesnt realy matter anything for overclocking wenn it comes to the AMD AM3+ platform.

The main thing that matters is the motherboards vrm implementation.

 

As a Asus M5A97 EVO R2.0 user, i can tell you that the 6+2 phase design of this particular board is more then enough to get a decent moderate overclock for any FX83xx cpu.

I reached 4.8GHz on aircooling from my FX8350, NB overclock.

 

FX9xxx cpu´s are indeed sorta kinda a diffrent story allthough they could work on this board.

Since i tested one on it, but i realy cannot recommend to buy a FX9xxx series cpu at all.

They are a waste of time.

 

But the Asus M5A97 EVO R2.0 is a pretty decent board.

Same exact vrm implementation as the M5A99FX R2.0

So what now? Cool VRM or not? Fan direction? I want to lower socket temperature...

It's not that simple, it boils down to the board. FX-8xxx do stress VRMs a bit with all 8 cores loaded, which is not an issue at stock speeds for some boards, but is for those boards marginally supporting the 8XXX chips (and this is true beyond this platform: in this same forum you'll find a Haswell motherboard fried during prime95). 

If instead of stock we discuss overclocking, then there is no denying 8xxxs will stress the VRMs, as 9xxxs are just OCed 8xxxs.

A motherboard isn't "more" nor "less" for overclocking by hosting a particular chipset. There is a correlation, as manufacturers tend to pair their best VRM designs with the 990FX chipset, but it's far from perfect. Some 970 boards will be better for OC than som 990FX boards.

Man, you are stuck in a loop: you keep asking the same question, you keep getting the same answer...

If you want a cooler socket, put ice on it. Yes, do it. I dare you.

Not needed.

Socket temps have nothing to do with vrm temps.

What are your actual temperatures?

Show some screens.

I am pretty sure that VRM dumps heat into the socket.

OCCT - 15mn

Prime 26.6 small fft - 2mn

[Sintezza]

I dont think that the vrm heat dissipation is causing your higher socket temp.

Idk which kind of cooler you use, but maybe ramp up the fans a bit.

 

[NelizMastr]

Yeah, which cooler are you using? Keep in mind CPU temperatures shouldn't exceed 70 degrees, or it'll start throttling very soon. 

[CyberWarrior]

Fans are on 80%, airflow is not a problem. Fans can`t help with socket temp.
I posted this before, I have CM TPC 600 + noctua 12cm industrial. Thermal paste is MX-4, changed 2 weeks ago, everything is perfecty mounted.
