problems oc'ing e2160

[Potatoboy]

First off, this is my first time overclocking. This is what i'm working with..

GA-P35-S3G
intel e2160
2 x 1 g.skill 800mhz
on stock fan.. but upgrading this week

I thought i'd toy with the settings while the fan shipped since i hear of ppl running stable at 3ghz on stock HS, but everytime i change anything it double boots and goes back to default settings. I tried as little as five clicks on the fsb and still no go. I then tried using the easy tune program that came w/the motherboard and was able to run at 2.4ghz overnight w/out problems, i just can't save it on the bios. wut gives?

The issue is that when I try to bump the FSB speeds by just 1 MHz, and save it, it reboots again and then goes back to the original settings. I've tried bumping the voltage, and even tried lowereing the DDR2 speed, but nothing seems to work.

After consulting w/ Google, I found that someone w/ the same problem used a Beta bios and got it to work, but I honestly want that to be the last resort. Anyone have any ideas at all?

You're probably driving the RAM too fast. I really suggest overclocking through BIOS. I've got a GA-P35 DS3R so oc settings are probably very similar. Kinda warm in SoCal so I kept my E2160 @ 2.40GHz (9x266, 57~59C at load). Maybe you can try copying mine and go from there.

My settings:
MB Intelligent Tweaker (M.I.T.)
CPU Clock Ratio: 9
CPU Host Clock Control: Enabled
CPU Host Frequency: 266 -> for 3 GHz, change to 333
PCI Express Frequency: 100 -> change from Auto to 100, probably for oc'ing gfx card, but keep at 100 until CPU oc is stable
C.I.A. 2: Disabled
Performance Enhance: Standard -> default Turbo may cause instability so change to Standard
System Memory Multiplier: 2.00 -> Auto sets to 4.00 which might be too fast for your RAM
Memory Frequency: (800) 533 -> auto-calculated based on cpu host freq and sys mem multi (e.g. 2.00x266=533, 2.00x333=667, 2.40x333=800)
DRAM Timing Selectable: Auto (5-4-4-11, 2T)
System Voltage Control: Manual -> setting to Auto would increase voltages as needed but the increase is usually too high therefore more heat is generated, maybe you can set to Auto at first then fine tune to lower voltages once you've reached 3 GHz
DDR2/PCI-E/FSB/(G)MCH Overvoltage Control: Normal
CPU Voltage Control: Normal
Normal CPU Vcore: 1.275V
RAM Voltage: Normal

C1E: Disabled
EIST: Disabled

Take note that not all E2160s can oc to 3 GHz. Some may be lucky to have one that goes up to, say, 3.6 GHz. Others might be limited to 2.6.

wow.. thx a bunch. everything is running great. running at 3 ghz with load temps at 57-59 with stock cooler.. and i just now received the new one so ima try goin a lil higher

Just curious, what's your room temp and what are your voltages? Also, what stepping is your E2160?

My E2160 is already running at 57-59C under load (room temp 24-25C) clocked at just 2.40 GHz with stock voltages. I don't wanna go over 60C so I haven't tried higher speeds, yet.

room temp is 22-24C on auto voltage for now... its an MO.

Thanks for the info. Looks like my HSF might not be seated properly... Or it might be lack of airflow. The PC is underneath a desk and there's like 1" distance from the wall and the back of the case (and thereby, the fans).

Lol, it's like there's a heater in the room. The room with this PC is the hottest in the apartment. Yesterday at 28C-30C ambient, it was idling at 40-41C. O_O

ya, i hate those plastic clips. i got the new HS installed and bumped fsb to 378 with vcore at 1.5 for 3.4 ghz.. running stable and 29 idle 54 load. extremely happy with the results
