E2160 Voltage

post #1 of 14
Thread Starter 
Hey guys,

I reached a point where I can no longer overclock at stock voltage. I need to overvolt but first have some questions.

Q1. What is the maximum safe voltage for an E2160?

Q2. What is the maximum safe load temperature for an E2160?

Q3. When I select the 1.325v option in the bios, why does CPU-z and Speedfan recognize the Vcore as 1.28?

I tried a BIOS setting of 1.33125v (which showed up as 1.296v in the programs) but I couldn't hit the magical 3Ghz mark.

Thanks.

the voltage difference is vdroop.I would up voltage 1notch more and check again.You should be safe to at least 1.44. but only go up 1 notch at a time .l

Q1: 1.5
Q2: L2 ->61c and M0-73c
Q3: That's vdroop. Vdroop is to describe the difference/fluctuation from idle to load. The idea is to proven the voltage reached to max voltage and drop back to a reasonable level so it can lowers the overall impedance. If vdrop too much, it will lead to a unstable system. So, when we say vdrop, we have three vcores, one for bios, one for idle and one for load. Therefore, you set 1.33 in bios, you may see 1.296 in idle then less 1.296 in load under cpu-z.

Ran it at 1.35v and 3GHz prime stable for 4 hours then played like 30 minutes of a game and got a BSOD. Lowered it back to 2.88Ghz and now I'm still BSODing. Did I fry my chip?

I don't think so. Maybe need to adjust the MGCH, FSB and DDR2 voltage or DDR ram timing in your DS3L BIOS. How's the temp for idle and load?

The only way it could have fried at 1.35v is if you had no cooling at all. My guess is either your cooler isn't seated properly or your RAM is OC'd too high.

no you didn't don't be paranoid, better check that speed you're ram is running on put it on a 1:1 divider

Hi,

i've got an Asus p5k mobo and the E2160 on it with stock cooling.Also got 2x1GB DDR2-800MHz with 5-5-5-15 timings (nothing special or super duper RAM).

I run totally stable @3.0GHz with 1.45V set in the BIOS.
All other BIOS settings are stock.

I'm running on this setup for more than 6 months now and never got a BSOD.

My guess is that you set the voltage too low.
1.35V is not enough to run stable at 3.0GHz.

Go for 1.45V.


With 1.45V and stock cooling i can run Orthos cpu-memory stress test for more than 6 hours without getting a BSOD and temperature (measured with realtemp utility) never gone over 59 Celsius.

Cheers.

P.S. If you want to run it @3.2GHz you need to set the voltage @ 1.55V.
I tried and it runs stable but runs also hot under this voltage. Needs something better than stock cooling.
With Orthos test @3.2GHz the temperature quickly climbed as high as almost 70 Celsius.
So i left it back @3.0GHz and 1.45V which is totally safe.

A1. 1.5v, but dont be scared to go a bit higher (1.54)

A2. Try and keep below 65C

A3. Its called vDroop, you can solve it with something called a vmod.

Your welcome *JaKe*

1. 1,5 as Lins said. mine ran at 1.425 for 3ghz so you've still got lots of headroom volts wise

2. i'd be wary of passing 80 under a prime / orthos run. i'm sure it can take more but mine ran at 55 in othos and substantially less under a normal load, imo you ought to be okay so long as you don't hit 80+ in Orthos

3. Vdroop. basically the voltage going to the CPU drops. the amount of this voltage is dependant on the board

imo jump up the vcore one or 2 nothces and test wiith prime / orthos for 8 hours, or OCCT for 2. 4 hours is not sufficient IMO
