Trying out the Phenom 955, suggestions on what else to tweak?

post #1 of 56
Thread Starter 
First time out of the gate tried to hit 3.6 just to see what it would do at stock voltage. Didn't get a post. Reset CMOS upped voltage to 1.4 and i've hit 3.6 and 3.8 Just testing the water so to speak. Thing is how many settings should i be fiddling with? I will be going back and working up slower. This Motherboard is ridiculous with the amount of tweaking options. From what i've understood for optimal system performance you want your HT link speed to be low and your Cpu/NB frequency to be high?

Settings right now @ 3.8

Vcore: 1.400
Cpu/NB voltage: 1.25
DRAM volts: 1.65 (stock)
FSB: 200
CPU/NB freq: 2400mhz
HT link speed: 1600
CPU spread Spectrum: auto
PCIe Spread Spectrum: auto
CPU load line calibration: regular
CPU/NB LLC: regular
Cpu Current Capability: auto
CPU Power Phase Control: standard
CPU voltage Frequency: Auto
VRM Spread Spectrum: Enabled

[AUTO]
NB Voltage
NB HT Voltage
NB 1.8v Voltage
SB Voltage
VDD PCIe

As of right now i've set the ram to 1600mhz (board limit for now) and left timings on auto which are 9-9-9-24/2T.

So should i be messing with other stuff such as all the stuff i have listed as auto? From reading around i haven't seen people just all out tweaking tons of specs on their motherboards as i had to with my Intel Rig. Although i might be reading the wrong guides. Any suggestions, criticism, etc. would be appreciated.

I do have to add being able to adjust the amount of Load Line Calibration is pretty awesome. Going to boot into windows and see if it will run a game or two to see what kind of performance gain i get.

HT Link frequency should always be left at (or close if you are overclocking via FSB and not multiplier) 2000mhz. Keep increasing the NB frequency, and CPU-NB voltage will help stabilize you. You can also tighten the memory timings down from 9 to probably 7. If it's a 2000mhz kit rated cas 9, it should pull off 1600mhz cas 7 no problem.

Increasing CPU/NB frequency also increases overall performance as your CPU speed increases correct?

So this doesn't require as much fine tuning so to speak as the C2Qs? With my 9550 on my x38 chipset i was having to test a bit here and there on CPU PLL, FSB termination, NB Vcore, SB vcore, and so on.
Right now windows experience wont complete

Settings:
vcore 1.406 (upped .006 to see if thats why windows experience was failing)
Dram Volts: 1.68 (same as above)
CPU/NB volts: 1.25
CPU/NB Freq: 2400
HT link speed: 2000

How are your temps at 1.45? I can't get it to pass windows experience with Vcore at 1.406, going to up it to 1.410 and see if it will pass that and IBT.

My temps are 52c max with Prime95 and mid 40s when gaming and that is using a Core Contact Freezer Heatsink with a 120mm fan.

What is your ambient temperature?

@OP

Be weary of socket temps, not so much the core temps.

Your HT link at 1600 is very low, stock is 2000. Keep it there or at 2200-2400. Up your NB speed as high as it can go as well. Turn off CPU/PCI-E spread spectrum. Turn off load line calibration and then adjust your voltage.
