1100T OCing help

post #1 of 19
Thread Starter 
Hi all,

Hopefully you gurus can help me. I hoped for 4.4 and have been told 4.2 is the average however, I'm struggling to get 4.2 no matter what volts I use up to 1.6. Temps are around 50C so it seems either the chip is at it's limit or something is holding me back, RAM, MB, me!

4.0 is stable with:

VCORE: 1.425v
CPU-NB: 1.375v
RAM: 1.650v



4.1 stable with:

VCORE: 1.45v
CPU-NB: 1.45v
RAM: 1.650v



Thanks for your help,
Croftie

Try dropping your ram multiplier so you can get it back down to rated speeds.

Lower your CPU nb voltage before you ruin your chip.
post #4 of 19
Thread Starter 
Ok lowered the ram multi but still getting a bsod.

What is the max CPU-NB voltage? The amd dragon pdf says 1.35v-1.50v, it doesn't say it's safe to use that but it doesn't say it isn't either. I also read that keeping vcore and cpu-nb voltage the same can aid stability, is that true?

I've set everything back to stock now accept multi and vcore. It's needing 1.55v to get 4.2 GHz stable.

Is this about right for a 1100T or do I just have a below average chip?

Sorry for all the questions, previously got an athlon 620 to a comfortable 3.4GHz but apart from that I'm new to this.

No do not make vcore and cpunbv the same. Ignore the PDF voltages, that is for x4 CPUs and outdated, you have an x6. 1.55 is way too high. Max cpuv is 1.5 it should be EASY to keep it at 1.45 or lower with llc enabled in the bios. Make sure cool n quiet and virtualization are disabled. Make sure turbo core is disabled. Cpunb voltage never go above 1.3, should be fairly easy to keep 1.25 or lower. I doubt you have a bad chip. What are your temps, what cooler u got? Past 4 ghz or so it really requires so much voltage to get diminishing returns in clock speed.

Oh you got a noctua, you should get 4ghz easy. If all else fails try 1.45 CPUv 3.8ghz llc on, 2.4ghz cpunb frequency and 2.4 ghz ht. 1.25v for those. OC with multiplier.

ht link above 2000 is bad...........
and most, from what ive seen to get 3000 or above cpu/nb frequency need high voltage, if temps are in check its fine just look at the crosshair iv club,some of them are higher than 1.5 cpu/nb volts for over 3000 cpu/nb frequency

try upping you regular nb voltage a little it helped stabilize mine i have mine at 1.2 norm is 1.18 when i tryed for 4.2 i had to up it to 1.22
try 1.475 vcore if that dont work try 1.5 for 4.2
1.22 nb
1.5 cpu/nb at 3000 or above
up ram voltage a smidge
up ht link voltage a smidge keep it as close to 2000 frequency as you can
turn off c1e and cool and quiet and turbo
and for temps you really don't want to go above 60c for a long period of time if ever

links to some of the reviewers overclocks and voltages

most of them have voltage in the 1.5 range for there overclocks and most also left the fsb at 20 and just used the multiplyer to 20-21
hope this helps

CoolnQuiet ect are all already off.. there is no LLC option on this board as far as I can see, which supprised me. Is there some way to enable it?

In my tests video encoding performance was best with HT link at 2200. Any lower/higher and performance was lower.

I'll raise the cpu-nb volts slightly then and see if it enables me to lower the vcore at 4.2GHz...

did you look at all the links?
and thats weird from every review ive ever read on phenom 2's it always said it ruins performance above 2000 ht link i edited my post above

Cpunb 1.5 is way too high. Why is ht above 2k bad? I read it helps stabilize the OC if it is the same as the cpunb frequency.
