Basics question on overclocking Intel i7 920

post #1 of 18
Thread Starter 
There are some finer details that with all my googling, eludes me. Nobody is giving a definitive yes or no on some things. My goal is to overclock my i7 to I hope around 3.6GHZ. This weekend I finally replaced the heatsink knowing before I do anything I need to have a better aftermarket one. I got a Thermaltake NiC F3, and used some Arctic Silver 5. I am curious as to a few things.

I installed CoreTemp and HWMonitor, I also installed Prime 95 to make sure I see a diff and heatsink is indeed keeping things cool.

Do I base my temps off of the 4 CORE temps or the 1 CPU temp??? I assume the CORE temps. I cannot get a solid answer on this. I put maybe a bit more than a pea size of thermal paste on the CPU. I may remove the cooler and put a literal grain of rice size drop, perhaps there is to much paste?

I ran Prime95 for 12 hours...The following are my MAX under FULL LOAD

Core 0: 67c
Core 1: 63c
Core 2: 65c
Core 3: 61c

Max CPU temp was 54c (this may be socket temp??)


Are these good temps at stock settings? I have not OCed yet as I am waiting for a week to let the paste cure. I know the temps will jump on an OC, and possibly by a ton, so I would assume I could easily see 75c on some cores. Are those temps reasonable?


When overclocking is it wise to set the fan to spin faster at all times rather than let it adjust based on CPU usage?


My system:
Windows 7 Pro
Intel SSD 128gb and WD Black 7200 RPM 1 TB
Gigabyte EX58-UD4P Bios updated to latest NON Beta bios
12GB Patriot Ram
Intel i7 920
Nvidia 560ti MSI Twin Frozer Gold Edition (MSI 970 on backorder buy incoming)
750 Watt Corsair PSU Gold 80Plus

Case has decent airflow.

Go off of the cores for temps.

The temps are fine, but figuring in for 3.6Ghz, the temps might be in the 90s. You want under 80'C at all times, so overclock what you can based on that.

If you want lower temperatures on a similar vcore/frequency a xeo. X5660 is like a i7 980 which is 32nm and just costs 100usd can be what need if you want a cheap upgrade

I would totally consider an upgrade, I never considered a Xeon as I always thought of them as very expensive, didn't realize they drop in price tons more than consumer processors. I will be using it to game, and will also be using graphic software such as Cinema 4D so I may really find this desirable. I know you can game on Xeons, just not sure how they overclock, I googled around and people say they do not OC very well???

I appreciate the input!

Welcome to OCN Quaglinoman, have the same motherboard and the max stable BCLK I have been able to achieve is 200, but that gives me 4ghz. on my I930.
I looked at your cooler and the images I found show it to be a direct contact cooler, i.e. the copper tubes come in to direct contact with the CPU, this makes for lower temps if the TIM is applied correctly, you said you used a pea sized drop on the CPU but did you pre-fill the voids on the cooler it self?

I will try to locate the guide I used for the two similar coolers I installed

Thank you!!

I just ordered an upgrade to the Xeon!

Thats awesome! Thank you! I will use that technique when the Xeon comes in!!

Ask on the xeon club which bios need your.mobo to support the xeon

Btw the guy was talking about direct touch heatsink not direct to die.there are few of those heatsink but the more efficient doesnt use that methodology..a glacer 240L or a h220/h220x would be better than any heatsink

Agreed, these old socket 1366 CPUs make a lot of heat, I cool mine with an Ek Supreme HF and RX360 rad
