Asking a huge favor (i7 920)

[Beitzel15]

System:
Asus P6T Deluxe V2 mobo
OCZ Gold 6gb of ram
XFX 5770 videocard
Intel 920 i7

I have turbo v with the motherboard but am a little unsure of how to use it or what to do. Im REALLY wanting my cpu to 3.0ghz. Im using a cooler master hyper n520 cpu cooler and idling at 37-40c.

My favor, can someone tell me on here or in a message, what I need to change to get my cpu to 3.0ghz, PLEASE. This computer is for my dad and I couldnt afford a more expensive i7 so I got the 920 in hopes of OCing it because he wanted the next cpu up from the 920.

Please help me out here.

Thank you!

I put the BCLK at 150mhz and increased the core clock from 1600 to 1800... what speed would that put me running at?

You should start here. http://www.tomshardware.com/forum/253365-29-core-overclocking-guide

You should be able to go well past 3.0ghz even to ~4ghz with good cooling.

I have the same motherboard and CPU as you and I was playing around with my overclock just tonight. This board makes it really easy. I've got a stress test running in the background now and seem stable with these settings. Generally you shouldn't blindly input someone else's settings into your BIOS, but it should give you a good starting point:

AI Tweaker: Manual
CPU Ratio = 20
Speedstep enabled
BCLK = 190
CPU Voltage = 1.200
QPI/DRAM Core Voltage = 1.200
DRAM bus voltage = 1.64

Everything else is 'auto' and whatever the defaults are. Temps maxed so far at 62c.

That's at 3.8ghz. I'm sure you can hit 3.0 with the same voltages. Just set BCLK to 150 and change the DRAM frequency to the fastest setting that doesn't go over your memory's specs.

I'm assuming your i7 is a D0. If it's a C0 you might want to start on 1.3 volts for CPU and QPI/DRAM and work your way down.


[Edit]: And good luck!

Thanks a lot! Im going to mess with it more when I get home later today. My memory is 1600. and how do I know what speed I get my cpu up to after all this? When I open up cpuid, it still says 2.67ghz

When you leave the BIOS make sure you press F10 instead of ESC so the changes are saved. The new speed will flash on the screen quickly during booting. Cpuid will show the new speed on the CPU tab, bottom left under 'Clocks'. It'll say Core Speed: 3000 MHz when the multiplier is 20 if you run a stress test, or it could say 1800 MHz when the multiplier is 12 if it's just sitting there. The Bus Speed should say 150.0 MHz.

The 'Specification' field will always say 2.67.

In the bios, i put the bus speed at 150mhz but on cpuid, it says 133.9. Core speed is 1606.6 at x12 multiplier at idle...and 2.667 at x20

When i restart and go into my bios, the settings are still as I put them but its like its not registering?

Weird. Are you sure you pressed F10 to save the changes?

 

[SpidersWeb]

Did it power on, then shut off, then start again?
Might've failed and reset itself.
Failures (if thats what its doing) are usually voltage or RAM speed related, and can be easily delt with, I just don't know enough about i7 overclocking to advise.

And don't worry about only getting the i7 920, at the prices, it's not recommended to get anything higher, and the 920 can be overclocked to the 3.8 to 4.4 range with good cooling.

The AI tweaker was set to auto, I forgot to set it to manual... so I set it to manual, and set it to 150mhz in the bios and it shut down, restarted and now it idles at 1800.0Mhz x12 and 2999.9mhz @ x20.

My temps at idle are

Core 0=44
Core 1=40
Core 2=40
Core 3=40

I did prime95 for about 5 minutes and the hottest it got was 73 and it only stayed there for a second, mostly stayed at 72c.

Is that good? Ive never had an i7 before, just my core 2duo and it idles low 30's

I gather that a max of 73 for an i7 is fine. It usually takes more than 5 minutes to reach the maximum temperature, though. Yours might max out around 75-76, but no real world application will keep it that hot, so it's probably fine.

Did you change the CPU core voltage and QPI/DRAM voltages? If you leave them on 'auto' this motherboard tends to overcompensate. When I had mine set on auto, CPU-Z would report core voltage at 1.24 or 1.26 or something at stock speeds, but I'm only using 1.208 volts with a 40% overclock.

Setting the voltages manually can greatly reduce the temperatures.

I changed the CPU voltage to 1.200 and the QPI/DRAM to the same and the DRAM Bus Voltage to 1.64

 

[cory1234]

Try lowering the voltage you can probably get to 1.1vcore for a 3.0ghz overclock. I wouldn't recommend using those settings if prime is passing 70C. That will definitely shorten the life of the processor, especially since over time dust will collect and raise the temps more.

 

[Beitzel15]

So from 1.2 to 1.1 and is the DRAM bus volt. good at 1.64?

I feel like it runs hot anyways. Stock, it was running high 30's.. 38-39c

Is that normal with an aftermarket cpu cooler?

 

[Beitzel15]

I feel like maybe I didnt put the thermal paste on right, but I put a really light coat on the cpu... the stuff was kinda thick though.

Beitzel15, I wouldn't be satisfied with temps in the 70's @ your voltage. If you have the time to take apart your dad's, do it. Because, it took me three tries to even get my I7 920 / AsusP6TDeluxeV2 W/ Corsair H50 @ 52C @ load w/ Vcore 1.92. The first and second time I was seeing 71C's, *Note* I7 @ 4.035, and the third time I simply didn't remove any thermal paste, however, I used a card to spread the existing thermal paste out, and added a TINY bit more Artic Silver 5.

 

[pluke the 2]

NOTE* These are when I applied the thermal paste when I had temps in the 70'S, and apparently this wasn't enough paste.

(above picture) this is my heatsink when I took it off the second time. The light area on the copper is the Artic Silver 5, the dark copper area is NO THERMAL PASTE AT ALL.

(above picture) This is my CPU after taking off my heat sink the FIRST TIME. The dark area of the CPU IS ARTIC SILVER 5, the other part has NO thermal Paste. I was getting Temps in my 70's @ 1.192Vcore.

(above picture) This is my CPU after apply THERMAL PASTE the second time, and the end results were the same, Loads in 70's. I don't happen to have the pictures of the third time unfortunately, I will only have Overclocking pictures.

Hope this will somewhat work if you decide to take re-do it.

ALWAYS USE ANTI-STATIC TOOLS!!!

Sorry for the SPAM of replies, but try turning off your Hyper Threading. May reduce temps 5min-10CMax

What does hyperthreading do, how do I turn it off and what effects will I see when I turn it off?

Also, it was only running 70's with prime95. It usually idles between 38-41

Anyone correct me if I'm mistaken.

Hyper threading in our case: Intel I7 920 has 4 CPU's, hyper threading enables each core to use 2 cores, essentially creating 8 cores. You can turn it off by going into the Bios, Advanced, CPU Configuration, Scroll all the way to the bottom, 5th from the bottom is called "Intel (R) HT Technology", Disable it. The effects of someone who ONLY plays video games will see NO EFFECTS. A person who uses the computer for DAILY things will see NO EFFECTS. It will ONLY EFFECT a person using the computer for ADVANCED EDITING or people who use Programs that require ALL FOUR CORES for their applications.

Pluke-

If your happy and the temps are in the 70's you are fine. Most Programs and Games, if your temps are in the 70's using PRIME95 will not exceed 62C on the hottest core.
