2180 Overclocking Issues...

Maybe someone here can help me before I put my foot through this build... it's essentially an HTPC build, but I want at least 2.8GHz out of it, 3+ if possible... which I know is possible from other's results...

Specs: Gigabyte P35-DS3L, e2180 (w/minja and 92mm fan), corsair 550w (new) psu, and crucial ballistix CL4 pc2-6400.

From what I've seen, most don't need 1.45v to hit 3-3.2 GHz, however my setup is wanting 1.5v for stability from Prime95 running off of a Ultimate Boot CD. Heck, it needs around 1.47 to boot into windows... The droop is about .3v. I have the RAM down low so as to not interfere with my results (750mhz for 800mhz native, have gotten it up to 925mhz though on 2.1v)

My current LOWEST possible volts for stability are as follows:
FSB MCH FSB
300x10 +.2 +.2

Anyone want to try to lend some light onto this situation? All components are actively cooled (ram, nb, sb, etc) and temps are not an issue with the ambient around 17'c in my basement. Power is also not an issue, volts are all nice and clean from the PSU. Did I just get a crappy proc or mobo?

Thanks in advance
 
I don't think there is a need to add voltage to the MCH and FSB, could actually cause instability, at least it does with my mobo.

you could try dropping the multi to 9x333 which I have found worked perfectly for me.
 
That may be a little worse than average, but not much. My e2200 is at 3 GHz. It needed a voltage bump to be stable at that speed. It can go to 3.3 GHz, but that requires 1.55v, and it's a furnace at that voltage and speed, even on watercooling.
 
Here are my results with a very similar setup:

I opted to move the E2180 into my shuttle (whole different set of OC issues there) and put a Q6600 on the DS3L (same everything else) and pushed it to 3.0ghtz without any volt bumps.

I think it is just that these E21X0 chips are more limited than anyone originally thought.

I just built a work computer for myself using the 2180, and to be honest it was the easiest build I've ever had. I'm at 3.2GHz with a very minimal bump in voltage, I believe I'm at 1.35 right now.

Have 2x2GB ram, a Gigabyte GA-G33M-S2L mobo and an 8800GTS in there with the el cheapo X-QPACK2 power supply and 2 1TB drives. This thing just screams and I only spent $400.

I will tell you one thing though, when I put the 8800GTS in I had to bump the voltage a little more on the proc, most definitely the PSU though.
 
It really depends on whether you get a good overclocking chip or an average one, I have an E2180 overclocked from the default 2GHz up to 3GHz, but I needed 1.478v (Vcore) and 2.3v on my Ballistix memory to get there, I'm pretty sure I could ramp it up to 3.2GHz but I'm not prepared to pump more volts thru the CPU to get there. A system builder on another forum has said that the last dozen or so rigs he built using E2180's or E2200's seemed good for between 3.0 - 3.2 GHz and nothing higher.
 
I got my E2180 late last year (November) and have been running at 3GHz with 1.34v but any more speed than that requires a hefty bump in voltage. I managed to sneak my way up to roughly 3.5GHz but at around 1.5v or so and wasn't prepared to let it sit at that since the temps were getting pretty high. These chips can usually reach 3GHz with very little, if any, voltage boost but any higher than that seems like they need a bunch more volts to be stable. Although, I am happy with it, I am starting to think I should have saved a bit more money to get something a bit better. But hey, its still a great budget chip.
