Intel E2160 + Gigabyte GA-P35-DS3L Overclocked to 3.06GHz

post #1 of 10
Thread Starter 
This is the first computer I've built by myself, and the first computer I've OC'd. I took the better part of today to go through and work my way from 1.8GHz to 3.06GHz, benchmarking each increment with PCMark05 to see what performance gain I was actually getting. I've attached an excel spreadsheet with all the data from each increment.

Can someone take a look at this and tell me if I've found a good max for my computer or not? I'm not very sure.

Thanks.

Could you please go to UserCP and fill out your system specs? I have a feeling you need to set the memory multiplier at 2.50.

Alright, I've filled out my system. Do you still think I should run the multiplier lower?

Why is the voltage for vcore1 and vcore2 different on your spreadsheet?
Are you setting the voltages manually, or using the auto-voltage function?

Well, it's what is coming out of SpeedFan, which I have recently read sucks a lot. I have the vcore set manually in the BIOS. At the end (and right now) it is at the default level (1.3250v)

Vcore1 will be CPU and Vcore2 will be the memory voltage.

Okay, set the voltage to 1.425V, the memory voltage to 2.2V, the FSB to 345 and the memory multiplier to 2.40 and boot her up. Make sure your timings are 5-5-5-18. Those are my settings see if they work.

Alright, I've got those settings in place. I set the memory voltage to +.4 in the BIOS, but vcore2 says 2.02. The memory says it normally runs at 1.8-1.9v. Is speedfan wrong or is that what's suppose to happen.

Yesterday I never messed around with the voltage settings for the memory. at +.4, how long would "normal" RAM last, because that seems a little high.

Oh yes, and if there is a difference between my BIOS idle temp and speedfan's, can I adjust speedfan to match what the BIOS says. I've got this huge cooler on the CPU, and I've done about 15 AS jobs on multiple processors before, but I'm maxed out at 61-62 degrees. I have the BIOS set to alarm at 60 degrees.. That hasn't happened and I've been at 60 for over a day.

The BIOS says I idle at 32, and speedfan says 40-41.

Anyways, I'm running F@H for the next day or two to see if this works, it crashed last night running the old settings. I'll probably run a mem test at the new speed/voltage if it happens again.

EDIT2: Just ran Prime95, the BIOS alarmed went off when SpeedFan said 74 degrees. When I set that offset into SpeedFan it matches what the motherboard temperature says for the CPU. I'm guessing this is a bit more accurate then.


EDIT: Sorry for all the questions, I'm running x86 Windows, when I switch to x64 will I need to change anything OC wise? Will x64 give me a better benchmark? This computer is used in a bioinformatics lab, and is almost 24/7 under full system load running genome programs grad students create (when they are unable to hook up to the Ohio supercomputer), will they see a performance gain if their programs are recompiled for x64?

Okay good work! That set up has been stable for me 24/7 for ages so I sort of chose that as my config and tweaked memory. To increase your overclock from there you mght need extra voltage. My E2160 got to 3.3 Ghz but my voltage was 1.5V BIOS and I didn't feel comfortable with that.

Download a program called "CoreTemp" and tell us what your temps are then

Also, a 64 bit OS doesn't make any difference to the overclock you will achieve.

I was using SpeedFan along side CoreTemp, but they both gave the same reading.. I'm guessing the sensors aren't accurate on my particular processor. I've had F@H running for about 10 hours, no crashes yet.

I wasn't too keen with 1.5v either, seeing it isn't my computer. The true test will come tomorrow morning when the first guy starts his project that will be running 24/7 for the next few weeks. I think I'll leave it where it is for a few weeks, and mess around with it later. 1.80ghz to 3.10ghz is a pretty decent overclock right? I'm 51-52 degrees under full load, gotta love AS5.

What would you say the max operating temperature for this processor is, I've heard both 50 and 60 degrees for someone overclocking?

Thanks a lot for your help, my first build + OC was a success!

Depends on the stepping. If it is an M0 then 72C is the limit otherwise if it's an L2 it's 62C.

Glad I could be of some use
