overclocking i7 950 with Asus P6X58DE mobo, need Help.

post #1 of 13
Thread Starter 
hi ppl,

i want a slight overclock of 3.5 or 3.6 for my i7 950 with HT,Turbo n speedstep enabled, as i am newbie in this overclocking n tweaking plz help me out.

my current system spec is

i7 950 @ stock
CoolerMaster Hyper N620
Asus P6X58DE
Corsiar Dominator 6GB 3x2GB(CMP6GX3M3A1600C8)
WD Caviar Green 1TB
Corsiar TX750W
XFX 9600GT
Dell ST2320L 23" Monitor
CM HAF 912 Case

Every thing ing bios is auto except some powersaving settings.
BIOS properties are:


BIOS Properties:
BIOS Type AMI
BIOS Version 0502
System BIOS Date 11/16/10
Video BIOS Date 07/27/09

BIOS Settings (ATK):
CPU PLL 1.800 V
CPU Voltage 1.22500 V
ICH PCIE 1.500 V
ICH 1.100 V
IOH PCIE 1.500 V
IOH 1.100 V
QPI/DRAM Core Volt 1.37500 V
CHA CTRL 0.500 X
CHA DATA 0.500 X
CHB CTRL 0.500 X
CHB DATA 0.500 X
CHC CTRL 0.500 X
CHC DATA 0.500 X
BCLK Frequency 135.00 MHz
DRAM Bus Voltage 1.65V
CPU Ratio 23x

My CPU is heating alot on stock maybe its coz of the voltages my idle temps are 45*c n full load in prime95 are 60-79*c within 10sec, why is this sudden jump of 18-20*c in temps ?

Airflow ,thermal pasting evrything is fine.

My room ambients are 26-32*c, what may be the issue ?
been using tunig tx3 thermal grease

This happened to me the first time I installed my H50 on that chip. I re-applied the TIM and re-seated the cooler and everything was fine. What method did you use to apply the TIM? I used to spread it evenly over the entire heat contact on the CPU but there were too many TIMs that didn't spread very evenly no matter how hard I tried. I eventually started applying a pea sized amount in the very center of the CPU and push the cooler onto the surface. When you push it down make sure to rotate the cooler a small bit in both directions to help spread it underneath.

With this method I've never had the temperature separation problems that I had when I used the spread method.

As for wanting to overclock your chip it's really easy to obtain the clocks that you're after. You really just need to adjust your multiplier and BCLK frequency to get to 3.4 GHz. Also, at stock speeds your QPI voltage is sitting pretty high. My 4GHz overclock only requires 1.3V QPI. I'd tone that down to around 1.2-1.25 and I'd also try to get that CPU voltage down to 1.9 or 2.0 at stock. The CPU voltage you're using now would be fine for a 3.4-3.6 overclock.

Just remember that when you up your BCLK frequency, your DRAM frequency is going to change as well. You need to make sure that your QPI frequency is exactly twice the frequency of your DRAM. So if you end up with 1400MHz on your ram frequency, your QPI will need to be 2800MHz.

So with all of that try this -

CPU voltage: 1.25
BCLK Frequency: 172
CPU Ratio: 21x
DRAM Frequency: **This will change automatically when you adjust the BCLK**
QPI/DRAM Volt.: 1.25
QPI Frequency: **Whatever your DRAM frequency ends up just multiply by 2 and that will be your QPI Frequency**

This will put you at 3.6GHz and it will also run cooler on your chip than your stock clocks right now. Those voltages detected by the motherboard are a little much IMO.

i did that before, evenly spreaded the tunig tx 3 on the chip with proper amount the problem here is the voltages when i reduce the cpu voltages my temps don't cross 60*c in prime95 test but the idle temps remain 44-45*c no matter what i do.

now the voltages are on auto coz the mod on anandtech forums told me my chip is not heating i7's runs hot but i don't understand on stock these temps are not satisfying me.

i have my cpu cooler fitted perfectly n the airflow is too good the problem is just the sudden 15-20 leap of temps on turbo mode.

i have been posting this on so many forums still no one was able to tell me what exactly is wrong with chip. i figuredout abt the load temps the problem here is voltages.

i'll do what you said but for right now i'll just change my QPI Dram core volt to 1.2500 from 1.37500 n chk the load temps.

plz tell me what exact voltages to be keep in bios for my mobo ?
the OC is later part coz i am still fighting with my stock temps.

Don't change any other voltages than what I recommended above. Keep everything else on auto. The drop in voltage on the Vcore and QPI alone should decrease your temps. I don't know why your chip is suddenly heating up like it is but with the board using those voltages on auto... seems a bit suspect.

dude i did just what you said but i was unable to change the dram frequency coz it was goin above 1600mhz in options, i successfully set cpu n qpi vcore to 1.25.
in the end i end \\up with underclocked cpu of 2.00 Ghz

i am uploading my bios pic now somthings wrong. i even tried to turn on intel XMP but whenever i turned it on the qpi dram gets at 1.40V amd ram voltages at 1.65
rest everything is on auto n i have turned on the intel C tech n asus Eup

The DRAM frequency changes incrementally as you raise the BLCK. You'd be just fine settling for a bit of an underclock on your RAM for now. So when you go to change the DRAM frequency after you've set the BLCK, select the frequency that's under 1600Mhz.

Let me try to get some pics of my BIOS and i'll show you what i'm talking about.

EDIT: Ok here's a shot of my BIOS -



You can see that when I changed my BCLK (base clock) to 191, I selected the highest DRAM frequency that I could use without going over my RAM's rated clock speed (my ram is rated @ 1600Mhz just like yours.) Now I'm running my BCLK at 191 to achieve a 4.01GHz overclock, in your situation since you're only going to use 172 on the BCLK, your maximum DRAM frequency is going to be lower. But that's alright, if you're feeling up to it you can overclock your RAM later.

Now that you have your DRAM frequency selected (remember, choose whatever the BIOS throws at you that's under, or as close to 1600MHz without going over) you just have to multiply that frequency by 2 and you've got your UCLK frequency. The UCLK or "uncore" frequency is what I was referring to when I talked about QPI frequency in my first post. I think this is where I threw you for a loop and I apologize.

Looking at my BIOS above you can see that I have my UCLK @ 3063MHz which is my DRAM frequency x2 (actually, it's 1531x2=3062 but the BIOS was playing it safe and had 3063 available for me.)

Everything I suggested to you in the first post is still accurate. So in order, you'd do this -

Change all of your voltages - 1.25 VCore, 1.25 QPI/DRAM, 1.65 DRAM voltage
Change your multiplier to x21
Change your BCLK to 172
Change your DRAM frequency (select whatever it has available that's under 1600Mhz)
Change your UCLK (multiply the DRAM frequency you end up using by 2 and use that number as your UCLK frequency)

I hope this helps you man and good luck with the overclock.

thanks buddy i got it now , i will try it now.

the c state is enabled in my bios shud i disable it + the load line calibration shud i enable it ?

i have not enabled the intel XMP profile, plz throw some knowledge abt it coz i don't know much abt intel's coz this is my first intel rig.

can i set ram voltage to 1.64 as its going to be underclock anyways, will it be stable ?

buddy i did just the way you said again the cpu is onderclocking to 2.80 ?

this is the bios pic of overclocking settings, i have just changed the Dram bus voltage to 1.64




this is the turbo v n cpu-z pic frm my desktop

^--- That's speedstep kicking in and underclocking the CPU when idle or not under full load. Feel free to disable it and your speed will be constant.
