Sometimes you might not need more voltage for these chips. So clear bios, reset everything, just up the multi to 20, turn off turbo and see if its stable. Then get it to 21 and see if its stable.

If the board allows to lower voltage, try that, atleast the chip and board will run cooler.

my guess is 4.2 would be ideal for that board.

Thanks ! I will do that after reading all the information I've got I understood what is going on. I didnt know that at high temperatures the mosfets will give lower amps. Either way I'm going to hell for OCing with this board so I will be happy with 4 GHz at default settings ! because money is an issue and I dont want to replace the board soon since its brand new.

I will try all default settings and only multiplier change. (should I leave coolnquiet ON ? what about other power management stuff ? all disabled ?) for example: C1E and C6 state and APM

L.E. doesnt boot at multi 20x with stock voltage. I need to up it a bit maybe +0.2V to get it to boot and +0.3V to make it stable. (I've noticed that voltage when turbo core is activated and set to x21 the voltage in CPUID goes up to 1.5 - so my guess would be is it safe for my CPU / mobo combination to use 1.5 with a 20x multi ?)

No it is not safe to run 1.5V infact I would not OC at all on your mobo just leave it at stock and be happy until you can afford a better mobo unless you like risking your VRM's burning out and possibly taking out your CPU when it does I just don't know why you must insist on doing something that me and several others have told you not to do

If u still have time to exchange, at least go with 970-UD3P R2.0. I just got one to replace one of my servers, so far testing it with FX 4130 at 4.6 Ghz, VRM stays cool. Of course its only a quad, but R2.0 seems much better than 1.0 I tried while ago.

 

[bernekus]

I cant exchange the motherboard sadly. I will stay with APM ON and HPC OFF and +0.24V on the CPU with a multiplier of 21x giving me ~4.2GHz with throttle in prime95 and very demanding CPU apps. I dont know if this doesnt equal stock

Can you explain me a bit further how APM really works ? and its connection to HPC and Cool'n'Quiet ?

Can APM bypass HPC ?

 

[Johan45]

That's exactly what I'm saying. If you put a fan on the VRM and one on the back of the board that would be good. I wouldn't overclock it any more. You already have nearly a 1 GNz. If you're not willing to upgrade the board that's as far as I would push it.

 

[Johan45]

APM is application power management and HPC high performance computing. APM has to be enabled to get HCP to work. Some of the throttling is because of this setting but on the other hand it's probably a good thing for you to leave it the way it is to help preserve your motherboard.

 

[Athlonite]

here bernekus this is a good read on what APM and HPC are for http://www.ronwoods.us/2014/02/what-does-amd-application-power.html

I will leave them both on then I just want to have a good gaming experience without throttling that is my main point to be honest.

I did read that before asking but thanks a lot for the link

TDP (of 95W for Vishera) is calculated at 3.3 GHz with 8 cores running ?

Hi there.
Long time since my last visit.

Last night I tried a little more OC to my pc.

4.2GHz at 1.4125v ran prime95 1 hour without errors
4.3GHz at 1.4125v unstable system freezes
4.3GHz at 1.4250v ran prime 95 1 hour without errors
4.5GHz at 1.4250v unstable system freezes

Here are some cinebench scores.

The problem is I've noticed that Load Line Calibration does not work proerly.

LLC possible vaules are: Auto, 1/2, 1/4 and Disable. 1/2 for AM3+ and 1/4 for AM3.

I've bought this mobo (Asrock 970 extreme 4) long time ago with 1.1 bios version and upgraded bios to support fx-6300.

With 2.2 bios version.
LLC set to 1/2 and Vcore set 1.35v, voltage readings (cpu-z, aida64, hwinfo64) are low in both idle and load, but when LLC is set to disable vcore readings are better.

So I decided try newer bios version 2.6, it is messy too.

For exemaple: changing multiplier, vcore and LLC.

4.0 GHz, 1.3500v, LLC set to 1/2. The readings are 1.37-1.38v idle and 1.32-1.33v at load.
4.0 GHz, 1.3500v, LLC set to disable. The readings are 1.44-1.46v idle and 1.41-1.49v at load.

4.3 GHz, 1.4250v, LLC set to 1/2. The readings are 1.44-1.45v idel and 1.39-1.41v at load.

4.2 GHz, 1.4125v, LLC set to 1/2. The readings are 1.43-1.44v idle and 1.37-1.38v at load.
4.2 GHz, 1.4125v, LLC set to 1/4. The readings are 1.44-1.48v idle and 1.43-1.48v at load.
4.2 GHz, 1.4125v, LLC set to auto. The readings are 1.44-1.48v idle and 1.43-1.48v at load.
4.2 GHz, 1.4125v, LLC set to disable. The readings are 1.44-1.48v idle and 1.43-1.48v at load.

Last night I downgraded to 2.5 bios version but it works in the same way that 2.6 version.

Any advice or sugestions are welcome.
Thanks in advance.-

PD: I dont know if other settings in bios affect what I'm doing, so settings in bios are:

Overclock mode ....................=Manual

CPU Dynamic OC.....................=Disable
PCIE Frequency (MHz)...............=100

[Johan45]

Yes from what I understand the LLC settings for Asrock boards are kind of backwards. The best setting if you can find it is to keep the load voltage and bios setting as close as possible. That may take a bit more testing on your end since I don't own one of those boards. That board isn't the best for overclocking either because of the limited power section so don't be surprised if it starts to hold you back. In the end you're going to need more voltage as long as the board and cooling can take it , to get that 4.5 you're aiming for.

 

[qu4k3r]

Thanks for your reply.

I forgot to mention that some times when running prime95 to check oc stability, multiplier and vcore change to x7 (1.4GHz) and 0.9v by themselves for a few moments.

Is that is a kind of power protection or something?

 

[Athlonite]

CPU Thermal Throttle...............=Auto

change that to disabled or off

that's why in prime it goes down to x7 and 0.9V it's throttling at high temps

I see no movement again for a long while so I'll just throw up a couple LN2 runs again.

What motherboard Are you running?
(I am on phone so cant see your specs)

From their sys specs, an ASUS Sabretooth 990FX R2.0
I have one of those just laying around. I also recently found a local supply of dice.
I.. I think I need a dice pot.

Nice, what motherboard? Do u have BD Conditioner installed? ...every bit helps lol

Edit: nvm I just noticed the BDC folder on your desktop.....

What's your score like on 1 core?

 

[FlanK3r]

Johan:

very nice! You can try superpi32M and 1M also, cause its possible do it 7800 32M and over 8 GHz with 1M (if you can run pifast at 7900)

 

[Johan45]

Thanks guys, I was actually running a CHVformula non z
@FlanK3r I was just running for a competition Diviv at the bot. Went on to 3DMark with a 290x matrix. Too humid water everywhere and nothing good to show for it.

 

[Athlonite]

the CHVF maybe getting long in the tooth now but still shows it has a solid bite when OCing great going Johan45 7.9GHz damn and all cores to boot

It's really not that different than the Z model

 

[eidairaman1]

It's really not that different than the Z model

Ok I think I found my limits, I think it may be thermal. at 4.7GHz I run mine at 1.381250Vcore for it to be stable in OCCT. At 4.8GHz OCCT errors out at less than 1.418750Vcore. At 1.418750Vcore OCCT hits 85+ C and stops. I presume my CPU cooler is limiting the overclock beyond 4.7GHz? I have my system specs. Do I need to go water cooling or change the fans to higher pressure models? What about Case fans too or does that matter?

I also noticed when I raise my case fan speeds for both intake and exhaust the CPU fans start jumping in RPMs. I have 2 Intake and 2 Exhaust, 230 and 140. for the CPU its 140 from Scythe
