piledriver - Official AMD FX4300,FX6300 and FX8350 review thread

[passey89]

Around 1.5v sustained.
Assuming you using the ASR Extreme3
Problem will be the amount of current drawn during the load testing.
If your using water the temps might be acceptable but the load on the VRM's will be significant, the board will probably throttlle the CPU or shut down.

I think my mobo was doing that when i tried to get it to 4.8 @ 1.47V after a couple of mins it downed my multiplyer to X7 until temps dropped 2C then went back up.

Look slike 4.5 ghz due to my mobo.

Still faster than the 8350 for £25 less

You could try upping the current limits in the bios and pointing a fan at the VRM's

BTW
Disabling the VRM protection could result in a loud crack and a firework display.
Don't do that.

Yeh not gonna mess with VRM settings. Its not like .5 ghz are going to make that much of a difference in games.

4.5ghz is good enough for me from a 3.5ghz cpu.

i'm re-installing windows 8 atm with my SSD's in RAID will try new overclockers later.

 

[passey89]

what are you using to read cpu temps?

 

[passey89]

now windows 8 is reinstalled on my RAID0 SSD's WEI score is 8.1.

I have 8.1 for everything but hard drive which is 8.3 will post screenie later

 

[passey89]

There seems to be a warehouse booking in issue that is holding up the CPU's other than the 8320. So it will not be this weekend, early next week I am reliably informed.

lol u'll get it sometime this year....

Hopefully....

maybe....

Weeellllll.....

We'll see.....

any idea what LLC is called in the ASRock extreme 3 990fx think im getting vdrop as its set to 1.45V but cpu-z is reporting 1.38 / 1.39.

I have also disabled

turbo
APM
cool N quiet

 

[passey89]

oc tweaker voltage control, should be cpu- load line calibration?

Keep an eye on the temps of the vrms fella

i'm not going over 1.45V so the heatsinks on them should be ok.

I jave a 200mm afn blowing down onto them anyway and a 120mm fan blowing in from the back as well

 

[passey89]

just disabled it thx volts up to 1.424v now.

It did say when I highlight it

Enable = AM3
Disable = AM3+

 

[passey89]

LLC should have different settings to control the voltage drop under load.

ASRock sometimes uses 0% to 100% or levels 1 through 5.
Level 1 is least vdroop

only settings were

Auto
Enabled
Disabled
Then the voltage settings for each thing

 

[passey89]

won't work.

As soon as I disable LLC it boots but if I run prime 95 it freezes.

 

[passey89]

wei as promised

 

[passey89]

passey would you mind doing a aida64 cache and memory benchmark between standard and your most stable overclock>?

u gota link to get aida64 from?

Just watching derren brown apoc then will do it

 

[passey89]

this is it at 4.3ghz (just what im testing it at atm).

trying to get memory up and vcore down a bit.

 

[passey89]

fritz chess score @ 4.3. No idea if its good or not

 

[passey89]

1090T at 4.06GHz for comparison (also running prime though)

can you do a x264 HD benchmark im downloading now to try it

[passey89]

I think the 8320 depending on your work load, or the FX6 again depending on your workload.
Really tempted to get one for the times I encode, either that or go full hog and get a 3930k

bit of a price difference between 8320 and 3930k though lol

 

[passey89]

y do I think my mobo might be playing up.

CPU running at 15C after 30 mins of being on. room temp is around 20C

 

[passey89]

my x264 benchie at stock speeds

 

[passey89]

It's not accurate at idle according to a few sources.

I think the best way to monitor AMD temps is to see if it's stable or not, none of their readouts appear to be all that accurate.

yeh I restarted and looked in the bios said 35C so i'm gonn say core temp is 20C off

This would be why I wa getting thermal throttling at 45C last night
