AMD® Phenom™ II Overclocking Thread

stanton4958 - you have to have your RAM sticks in the correct slots to run in dual channel mode. Check your motherboard manual. Failing that just try the different possibilities until it says dual. It is usually that the sticks need to be in slots of the same colour. I think.

thanks a lot mate put them back in the blue slots

nice 1

Much better


Now, quick question to anyone on here with an ASUS board.

What's all this new fancy LLC %'s all about...

I'm used to mobos that have two settings for LLC... Enbled... or Disabled!


What's the best % to set the LLC for? as I'm getting fairly large V.droop under load. (LLC currently set to Auto).

 

[Martini1991]

I remember my gigabyte had no LLC control =/.

 

[eddyc]

Hex - this has been gone over several times earlier in the thread. Set to 19% (or closest) and forget. It should eliminate vdroop almost completely. Pretty good

 

[Martini1991]

My gigabyte had no vrdoop.
They're like completely stable.
Either way, Hexcore soon XD.

eddyc:

Ta muchly, will give that a go when I get in

 

[eddyc]

Martini - I dont know why asus dont just set it to 19 by default. Would be helpful.

Hex - no worries. It might even allow you to increase your OC / reduce your vcore a notch since you are not having to deal with vdroop any more.

 

[HeX]

Yeah i'm hoping I can turn down the voltage in BIOS, as i'm having to set around 1.42V to get 1.36V load with LLC on Auto, which is terrible!

Bit of luck with 19% LLC I can crank that down to closer to the load voltage.

 

[Martini1991]

Don't even ask me on voltages.
CPUZ reporting 3.7v...
Stupid board >.<

 

[eddiew]

Pantburgers, failed after 3 hours - but gracefully, just a single thread not a bluescreen/reboot. This is progress...

What's more likely to get it solid, another voltage notch on the CPU-NB, or on the RAM itself?

 

[eddyc]

have you done plenty of memtest? I guess if it passes memtest then cpu-nb voltage is a better choice.

to anyone who has a dual that wont post when unlocked:
try lowering the HT multi a few times and then try unlocking it. mine wont post at all untill i lower the HT multi to 8x, but i can set this back to 10x/11x in windows using overdrive.

 

[eddyc]

Good find

I have always wondered about this. What does it actually do? I have always assumed higher is better but not sure that this is really true. Cant help thinking I might get a better overclock with a lower ht multi. Might have to give it a go.

Hex i have been doing a lot of testing with my asus LLC setting, i have mine set to 9.35%, im clocking at 3.7ghz with a vcore of 1.43125v, when i test with my prime the most the vcore dropped to was 1.39 it stayed around the 1.44-1.45 mark most of the time, the main thing was it did spike up to 1.52 at some point according to hardware monitor which was worrying me a little i tried 3.8ghz with a vcore of 1.45 and the lowest it dropped was to 1.42 and it spiked to 1.57 at one stage again according to hardware monitor. The LLC deffo makes a difference i changed it to auto which is 51% just to see the outcome and it crashed straight away, Just be carfefull as Asus seem to have got there numbers round the wrong way settin it to 100% you would think turns it off it doesnt that increases the vdroop, if you want to turn it off all together set it to 0%.

Hope this might help you a little bit

Looks like they removed it totally from the M4A79XTD Evo ... lol I just spent 5 minutes hunting in the bios for it !
I am getting around 0.02 droop, and also the manual setting for vcore in bios is listing close 0.04 to 0.06 more than cpu-z/hwmonitor reports.

 

[HeX]

Well I was running 1.45V in BIOS to get 1.36V under Prime/IBT using AUTO (51%).

Changed it to 19% and now I can run 1.4V in BIOS to get the same, muchos improvement

 

[eddiew]

HeX, where exactly in your bios is that option? Lol, I have the 795 evo and can't for the life of me find the bugger xD

*edit* Ah, I'm not alone in it then Vogon :<

 

[HeX]

JumperFree section, in the same place you change the CPU voltage.

 

[eddiew]

Ah. Then it has indeed been removed from the 79X, cos it ain't there Maybe there's a later bios than November 09 I could get that would put it in... *edit* no there's not Oh well, 0.02v drop under load isn't particularly harsh.
