Ok guys so i've had my new rig built (everything from OCUK :D) for about 2-3 weeks now and I feel its time to overclock.
Specs:
CPU: AMD Phenom II X6 1055T @ 2.8Ghz (Stock)
CPU Cooler: Coolermaster V8 HSF
Motherboard: ASUS Crosshair III Formula RoG
RAM: Corsair XMS3 4GB Dual-Channel 1600Mhz Kit (2x2GB) Running @ 1600Mhz

Here is my CPU-Z:

Here are my temps at idle:

Here are my temps under full stress on prime 95:

Note: Everything is still running at stock, i have not changed anything.
Does anybody know any overclock settings for me to get my 1055T up to about 3.2 or 3.4 Ghz? I really need these; CPU Freq, CPU Voltage, DRAM Freq, DRAM Voltage, NB Freq and anything else you would need.

Please help meh, tah guys ;3
 
I use 250MHz fsb at 14x multi with vcore at 1.275V in bios, 3.5GHz. My dram multi is set at 6.67x giving 1667 MHz, dram volts 1.6V. NB and HT freq. 2000MHz, 8x multi, auto voltages.

Hope this helps.

Try going up in 10MHz fsb steps from 230MHz which should be easy. I got to 275MHz fsb on that vcore, but am using 3.5GHz as a 24/7 OC. Turbo is off but cool and quiet is on. This is prime95 stable as it was with 14 x 275, 3.85GHz. I get 47C max at prime95 load at 3.5GHz.

Whats the 1055T temperature safe range? i was told that its max before going unstable was 45-50C?
 
Oh and btw, which of those temperatures is correct? i have temps for the actual processor, e.g. core#0, core#1 etc. and i have a temp called 'CPU:', which one am i actually looking at? my cores say about 16-18C but the CPU one says 30?

Keep it under 55C the CPU is rated at 61C I believe. Ignore core temps as they are not the CPU temp and on my system are 10C less than CPU.
 
Also while your overclocking the fsb, make sure that you reduce the dram, HT and NB multipliers so that you do not get fails from them, you can adjust them back up afterwards when you have your required overclock.
 
Im a bit confused about this.

Here are the settings im using:
Core speed: 3430.2Mhz
Multiplier: 14x
Bus speed: 245.0Mhz
HT Link: 1960.1Mhz
NB Freq: 1960.1Mhz
DRAM Freq: 653.4Mhz (i think its running at something like 1307Mhz?)
FSB: DRAM 3:8
RAM Timings: 9-9-9-24

Ok so my CPU is idling at about 32-40C and when i put it under prime 95 for about 5-10 minutes i got this;

I took that picture right before i cut off prime 95 because i was worried about the temps but at this point the temp increase was very slow but it was still going up in farenheit ever so slowly but starting to stop, but i didnt want to go any further.

I have a coolermaster V8 and the Antec 1200 case, all fans on lowest setting and the CPU fan, i have the dial turned up just a tiny bit from the bottom. and i get those temps.

I also maxed out every fan including the CPU fan and it hardly made a difference, is my temps bad ? :S
 
You are typically 7-8C higher than me, it depends on several variables, ambient temperatures, efficiency of cooler (my TRUE against your V8) fans and airflow, I have three 120mm fans including the TRUE, they operate at 800-1000rpm under load. I have a PWM profile where fans are 10% at 35C and 100% at 55C.

Your temps look safe and after 10mins prime should be quite stable.

Ok, ill keep it at 3.4Ghz and prime95 it for 30 minutes while i go eat lunch and ill see what the temps reach when i get back, if they break 55C then ill go to about 3.2Ghz and try that. But then again i think, and you probably will agree with me, when will you ever put every single core on a 6 core processer under 100% load unless your stress testing or rendering something very very very very very very (hence lots of very's) big. right? ^^

I agree with your last statement, I have never seen 100% core usage on six cores in anything (except stress testing).

Ok well thank you so much for your help andy :) ill be sure to ask you if i need help with something ;p
 
quick question what vcore are you using, undervolting can be useful if the temps look high and it remains stable?
 
CPU Vcore is unchanged at 1.350V, which is what it came as when it was at 2.8Ghz stock, i havn't changed any voltages on my system at all since i built it
 
Try it at 1.275V (-0.75V) as mine runs quite happily at 3.5GHz using this, it will lower your CPU temps.
 
Mine is 1.275V in bios, 1.264 in CPUz last I looked. Go down one notch at a time and boot into windows, then run prime for a while.

should i drop it to 1.3V first and prime95 for about an hour while i play CoD on my xbox then if its stable drop to 1.275V and then do the same and see if its stable? :D

Btw i have enabled Cool'n'Quiet in my BIOS so i idle 980Mhz (1.225V) an a cool 29-32C ish..
When its at the full 3.4Ghz it runs at 1.35V, so if i put it to 1.275V it will idle at like 1.1V? or something? does that sound about right or should i turn C'n'C off?
