Phenom II X6 1055t on GA-970A-UD3 NEED ADVICE - Page 2

post #11 of 16
Thread Starter 
Update:
I made my phenom boot at 286x14 !!! Here is my Validation: http://valid.x86.fr/xnh9dz. It seems that I need a higher NB clock (used the 10x Multiplier) to boot. But Prime 95 crashes imediatly after booting up my system but now I know that my CPU like a high NB clock. maybe I can improve some settings.

Settings were +0.225V Vcore , +0,2V CPU/NB

unfortunally I still was't able to get this settings to work. My last hope is that somebody has a hint for me what voltage I have to tweak to get it work.

Maybe I just got a weak cpu that doesn't like overclocking that much.

If you look back at post #4 spoiler and post a few snips (like this one showing test failure) and if possible show a few snips of current bios settings I'd be happy to assist you.

Thank you, I hope that I've taken the screens you want to see.
3,5 Ghz Settings (current setting): (Click to show)




I'd have to say that my board only allowes me to set voltage in 0.025V steps. Anyway I have lowered it to +0.03375V with PhenomMSRTweaker. With vdroop included I get 1,333V under load.
4 Ghz Settings (unstable): (Click to show)

The bios snips helped.

Start by always keeping the HT Link Freq as close to 2000MHz (+/-200MHz) as possible. Not 1400 - 1600MHz this can cause issues.
When I look back at post #8 settings you were probably closer than you think.

You've already seen you'll need a higher NB Freq (very common) and it will help allow you to clock higher.
You'll be testing both CPU and NB Freq in the same test (draw back with an unlocked multiplier) but maintain that HT Link and it'll be much easier.
I'd start with 2600 to 3000NHz NB Freq (when possible) and try again. Phenom II CPU/NB voltage max is 1.5v, same as Vcore. I'd guess it's the NB core in your bios.

Referring back to post #8 and NB voltage,
The actual NB (chipset) voltage may need to run 1.2 to 1.3v+ this stabilizes the increased ref clock. (very important one here) you'll need to test to see what your system requires.
Keep a written record of failure times/settings during stress tests and after making a few small increases/changes you'll start to see failure time either increase or decrease which will tell you if you're moving in the right direction. Change only one setting/area at a time.

One more thing to consider is that as you raise the CPU and CPU/NB freqs you will also (eventually) see a need for additional Dram voltage.
The Dram voltage listed by the manufacture is rated for Intel (1.5v) and it's not uncommon with the AMD platform to use .05v to .1v additional dram voltage even at stock timings.
As you raise these freqs consider adding more Dram voltage. GSkill can easily handle 1.75v without any issues. (not that you'll need that much at this point)

A couple things I do when running P95 and you get errors/failures,

BSOD, usually a lack of Vcore

Freezing is usually a sign of a lack of Dram voltage and or CPU/NB voltage (sometimes a combination of the two)

When you get a "Worker Has Failed" in Prime95 and it's not temp related I usually treat this the same as above.
Start with a few adjustments of Dram voltage while watching failure times and if that doesn't help return Dram voltage to previous setting and then try CPU/NB voltage.
If that still doesn't help then back both of them up and try in combinations.

And yea, 3.8 is a 1GHz OC on the 1055T which is very respectable and if your chip is capable of 4.0GHz I wouldn't expect to even try that one till I had the 3.8 well under control
to give you an idea.

3.8 will probably take a lot of testing to stabilize so be patient.
I'd try to choose a Ref Clock that I could easily get to 4.0 and keep NB, HT Dram within reason but stabilize a 3.8 as close to those settings as possible by whatever means ness Thinking maybe 1 under max CPU multiplier (if possible) or even 8MHz on the Ref Clock so after 3.8 is stabilized you won't be needing a lot of adjustments to hit 4.0

Take your time and keep good organized notes as this will help you the most.
Watch those failure times and you will see a pattern.

Please post your test results with CPUZ showing both CPU and Memory tabs along with something like either HWInfo64 or HWMonitor showing voltages etc when under load.
This will also help us help you.

Good luck and have fun!

"Start by always keeping the HT Link Freq as close to 2000MHz (+/-200MHz) as possible. Not 1400 - 1600MHz this can cause issues."

Sure but it is at or near 2000 because this setting in Bios represents a multiplier. So 1600 is the x8 multiplier and 1400 the x7.

Thank you very much for your great tips. I'll test them soon and then share my results with you.
