E2180 voltage question

[batgosho]

I have a E2180 working on 3000Mhz very well.I tryed to see what's the max it can go.Starting from 3000(300x10) I raised the fsb to 310.It was stable.Passed some tests(3d mark05 and everest).The tryed with 320 and as I started 3D mark 05 the pc reboot.I tought it was the voltage that caused the reboot.It was on auto (1.256 shows CPU-Z) so I made it 1.375 and it refused to start Than I made it 1.275 manually and it didnt start again.Damn!I even tryed to raise the voltage on 3000Mhz and again no start.Why is that?
Currently I use 3000Mhz(333x10)and its stable
By the way this is my first post here

You are crazy undervolting that chip. The stock is 1.325. It will not run 3.0 at those low numbers. To get 3.0 I need 1.39xxxv raise it more

 

[batgosho]

Actually the stock (auto) is 1.256V if my cpu-z is not lying me
I run it at auto right now on 3000Mhz
Will make screen if u want

Depends, is C1E on?

 

[batgosho]

C1E Support Enabled
here is the full config.
[ASUS P5K SE|CoreDuo E2180@3.0Ghz|HD2600Pro 256MB DDR3|250GB Seagate|2x1GB DDR2|FORTRON 350W]

If C1E is on and it's at idle it will undervolt... So that's not your default voltage.

Check CoreTemp and read the VID.

 

[Silverion77]

that chips stock is 1.325 guranteed
I have the exact same chip and its 1.325

the BIOS should tell you that.

Cmon dude, VIDs are different. Stock isn't you are right on that... But each chip might have a different VID.

 

[Silverion77]

I understand that cnumartyr but 1.256 seems pretty low

If I were him I'd go higher (1.38+) than tell us what his results are

Oh I agree, I still think it's an undervolt from C1E.

 

[Evilonigiri]

Wut? I thought 1.375v is plenty for a 3.2Ghz OC? Heck, 1.35v is more then enough.

 

[Silverion77]

Evilonigiri...

the E2180s do not overclock nearly as well as the E2160s (hate to say it), but its true. You can see people configs like mine and Bilbos whose voltages exceed 1.39v to get above 3.0

So I've heard. I knew it was bad, but I thought it couldn't be this bad.

 

[Silverion77]

I kno its dissapointing....I think it either has to do with the added multiplier or its the different dump chips (I think E4500s and E6xxx) they are using

 

[batgosho]

So should i raise the vcore and how much for 3.0

 

[Silverion77]

try around 1.39 and go from there....if it reboots on Prime96-small ffts test then it probably needs more so keep raising it bit by bit.

Watch temps...1.39 on stock cooler got me to 65+

 

[batgosho]

One more question
Do I have to turn off C1E?

 

[Silverion77]

At first, it helps get a stable overclock.

Once you have a clock you like you can try to turn it on to save power etc.

In my particular case I went to 1.4125V for 3Ghz. I ran about 5~6 hours prime stable at exactly 1.4V so I upped it up a couple notches to get that rock solid prime. But now I got greedy and decided to go for 3.2Ghz. Kind of scary/borderline I have the voltage in BIOS at 1.5312V (I think). In windows I idle at 1.504V and under load it droops lower to 1.47 (I basically droop about .06V under load!) This ran prime stable for 6 hours, I've done some hours of gaming with no crashes though which I thought was impressive. My super safe OC was at 2.75Ghz at bone stock voltage with all power savings features on. I plan on replacing the E2180 with a Q6600 when it gets cheaper in the next year or two.

bildo123 what cooler do you use (dont tell me its the box)
raisng the vcore more than 1.5...courageous

LoL I have that one sitting on a coaster of CD's. I'm using a CoolerMaster Hyper TX-2. Yesh, I am pushing the thing to the very edge...But I dunno, I do plan on replacing it in a year or two depending how fast the price drops on Q6600's. It's that or I can run this thing on stock voltage @ 2.75Ghz w/power savers or I can run it at straight 3Ghz at about 1.4125V BIOS. I dunno, I'm already having second thoughts about going back to 2.75Ghz just so I can use the power savers again. What do you guys think I should so? Go to 2.75Ghz or full bore at 3.2Ghz? Also, does running RAM at a 1:1 ratio increase stability? I never tried using the x2 multi for ram, when I played around I always used 2.4/2.5.

I've had the vCore up around 1.5 on my Q6600.

It'll be ok, I promise.

Edit: Just pay attention to temps.

 

[bildo123]

Well I can a memtest86+ last night for about 9 hours and noticed I recieved an error. So now I'm doing testing and I backed up to 3Ghz again with the 333Mhz FSB. I think it's cause of my timings that it caused an error, but now I set it all to auto and im going to see if I error again.

Same problem is mine, cpu-z lies, try volting manually =<1.5
