Hello all,
Trying to ramp up the speed on my system. I'm pretty new to overclocking, but I did take the time to read a few threads and Overshocked's tut page (which was very informative)
First off, here's the rig:
i7 920 D0 stepping 166*20 (3.33Ghz)
Cooler Master Storm Scout Case http://www.newegg.com/Product/Product.aspx?Item=N82E16811119196
MSI X58 Pro LGA 1366 Mobo http://www.newegg.com/Product/Product.aspx?Item=N82E16813130221R
Cooler Master Hyper N520 CPU Cooler http://www.newegg.com/Product/Product.aspx?Item=N82E16835103057
OCZ Platinum 6GB DDR3 1600Mhz (3*2GB) http://www.newegg.com/Product/Product.aspx?Item=N82E16820227381
Corsair 650TX 650W PSU http://www.newegg.com/Product/Product.aspx?Item=N82E16817139005
XFX Radeon HD 4850 1GB GDDR3 GPU http://www.newegg.com/Product/Product.aspx?Item=N82E16814150351
All voltage settings are on Auto, except the DRAM which is set to 1.65V. Temps at 3.33Ghz are 39~41C Idle and 67~71C Full Load under Prime95. That seems a bit high compared to all the other threads I have read. My goal for this chip is 3.6Ghz~4.0Ghz.
I have tried the settings at 175*21 (3.67Ghz) with no voltage adjustments to the CPU/QPI/or NB. The temps were 46~48C at Idle and Mid 70's C once under load. Also, 190*21 (3.90Ghz) using Vcore 1.28V, but the Load temps were 77~81C and Prime95 BSOD within the first minute. A little scary.... I also tried 200*20 for 4.0Ghz; Vcore at 1.35V. The system did boot to Windows, but once again BSOD as soon as Prime95 started working.
I have reseated the Cooler once, but there is a chance I used too much thermal paste when reseating. I used Antec AS5, the line application method. I was told this is almost as good as Arctic Silver 5.... I have turned the system to it's side, also I have removed both side covers....All with no noticeable change to idle temps.
I am aware that the IOH needs attention in that it idles at oh.....80C.... I do plan to remove the sink and reapply thermal paste to bring this down. Could this be holding back the overclock?
I did spend much time reviewing my HSF, but now I wonder if it's not up to par for the overclocking....
Also, the max speed I can set the RAM to is 1333Mhz, anything over that, the system will NOT post. I don't know much about timings, so If I need to tinker with those to get it to POST...Well, I'm open to suggestions.
Current Settings
Bclk - 166*20
Vcore - Auto
CPU PLL - Auto
Dram - 1.65V
QPI Voltage - Auto
NB Voltage: Auto
EIST: OFF
Turbo: OFF
C1E: OFF
Spread Spectrum: OFF
The case seems to have good airflow, I even purchased 2 Cooler Master 120mm Case fans for the side window to blow air onto the mainboard. The CPU HSF is of Push-pull type, but I'd really like to see Idle's in the low-mid 30's and Load temps no more than 65C. Is this possible at 4.0Ghz? What would ideal temps be at 3.33Ghz?? 3.67Ghz?
Once again, Can anyone give me a few tips in order to get this up to 4.0Ghz, or somewhere close to that??
I hope I don't have to look into another cooler.... as I spent a few hours dealing with a crappy install diagram which originally led me to install the cooler backwards. Someone did recommend the Scythe Mugen 2 whilst I was building the system. Also the Core Contact Freezer has me intrigued, since Overshocked has an i7 running at 4.53Ghz with it.... But, once again, not having to buy another cooler would be a plus.
Any suggestions are greatly appreciated!
EDIT: All temps recorded using Core Temp 64bit
