Worried about Voltage

[Rip181]

I just recently put the following system together,

CPU: Intell E2200 (Old Zalaman CPNS9500 Cooler)
MB: Abit IP35-E
Ram: Adata 2 Gig PC6400
Video: Nvidia 9600 GT

I am planning on Overclocking the chip to 3.0+ but after looking at intels specs (http://processorfinder.intel.com/details.aspx?sSpec=SLA8X) it says max voltage of 1.312 but the lowest my vcore can go is 1.325 in the bios. Am i looking at the wrong thing or Am i running the possibility of ruining the chip. So far I have overclocked the chip to 2.7 but going to 2.8 the system will restart once windows loads. The temps are good (26°C idle 47°C Load). I would like to push the OC further but I was worried about the max voltage I can use.

On a different note the system is running great, I know 3Dmark is not a great real world test but my score went from 1715 to 9602 so I say that is a nice increase.

old System:
P4 3.0
2 gigs of pc 2100
Asus P4C800 Deluxe
ATI X850 pro

First of all, that chip should be rated up to 1.5V. I have my E2160 running at 1.49V at least 8 hours a day. Increasing the voltage increases the heat that the chip produces and can shorten the life it.

Second, your 3DMark probably went down because you were running 3DMark 05 or < with your old system. Now you should be running 3DMark06. That looks like a good score for your set up.

My chip @ 2.8GHz and my 8800GT 512 @ stock can prolly hit those 3DMark numbers.

If I take my chip to 3.2GHz and OC my card a lot, in my mind, I can hit 12000 in 3DMark06. For me, this took weeks of shooting for a very stable OC. So take your time.

Try CPU Voltage of 1.3875V for that 3.0GHz OC, but make sure you read an OC guide first and make sure you have certain things turned off and some other things manually adjusted.

Good luck.

I'll second this. A voltage before a hastened death would be above 1.5V in windows. Depending on the mobo your voltage droop can be less or greater but you can easily check it with CPU-Z. For a rough guesstimate just try not to go over 1.5V in BIOS. Personally I believe you wont need anywhere near that much to get the E2200 to 3Ghz. For starters you can try 1.4125V in BIOS like I do for my E2180 @ 3Ghz. From there run the normal prime tests while checking for temps and lower or (unlikely increase) the core voltage to get it stable. The goal is to get it prime stable with the least amount of voltage, saving you heat and life expectancy of the cpu.

Thanks for the advice, I guess I was really worried that the On teh Intel Spec sheet it said max of 1.312V but all the other pentium dual-cores are 1.5. I will try it out and see what happens.

When I tried 2.8 I only locked in the pcie voltage (100) and vcore (1.325) left everything else auto but I keep trying to keep my ram close to 800 which I think was causing problems, so I will set it to 1:1 and see if 2.8 or higher sticks. The Temps were good I think no where near the 60°C max at 2.7 so I think my old Zalaman 9500 is doing a decent job.

I know the OCguide says to turn off all the energy savings features but does it really matter? or is he saying to turn it off just to eliminate a potential problem? I left those all on btw.

Interesting, the other 65nm C2D/C2Q shows the VID max as 1.5000V. I wonder why the E2200 shows up as 1.312V? http://processorfinder.intel.com/details.aspx?sSpec=SLA8Y

In that link, the E2180's max VID shows as 1.500V. The E2220 also shows up as 1.5V.

ya this is why I got worried. the lowest voltage my motherboard would allow was 1.325 so I was wondering if it was overvolting already. does the motherboard get the minimum voltages from the chip or is it just built into the BIOS.

It's built in, thus there's tons of voltage option.

I would expect that the min voltage to lower than 1.325v. Do you have the latest bios installed?

 

[Rip181]

they just released a newer one but I have not tried it. the board came with v15 and they just released v16

Read the OC guides. There are some things that need to be disabled in BIOS.
