I've got a new E2180 and a GB P35-DS3L that I'm trying to overclock.
Here are the full specs:
CPU: E2180
Mobo: GB P35-DS3L Rev 2.0
RAM: 2x1g g.Skill DDR2 667 (F2-5300CL5S-1GBNJ) 1.8v
GPU: XFX PVT73GUGF3 GeForce 7600GT PCI-E
HDD: Hitachi 160g SATA2
DVD: Asus 16x DVDROM SATA1
PSU: Rosewill RP500 500w (it'll be sometime 1Q next year before I can replace this)
HS: Enzotech Extreme-X
FAN: Scythe S-Flex-D (800rpm)
Case Fans: 2x Scythe S-Flex-F (1600rpm)
Case: Rosewill R6AR6

I have C1E and EIST turned off.

System Memory Multiplier is set to 2.0 (keeps the ram @ 1:1)
All voltages are on auto

The max I've been able to get stable so far is 305mhz FSB. idle vcore is: 1.392 load vcore is: 1.360

When I push the BS to 310 mhtz I start getting errors in Orthos (very quickly, like the very first test). First time I got error on the 1st core, second time I got it on the 2nd core.

When I tried to push to 333mhtz BS (prior to trying the above speeds) it wouldn't boot into windows. It would post, but before getting to the loading windows screen would restart.

My core temps @ 300 BS are 19 idle, 51 load. Not bad at all for an 800 rpm fan. Temps with the stock intel cooler were 22/53 @ 266.

So... What is the next step? Should I set the vcore manually? If so, should I leave the other voltage settings on "Normal" (these include DDR2 OverVoltage Control, PCI-E OverVoltage Control, FSB OverVoltage Control, (G)MCH OverVoltage Control, and CPU Voltage Control (vcore I assume)) or should I be setting them as well?

Any help pushing this machine to the next level would be appriecated.

Thanks.

haha during first read I thought BS was Bull Shit, took a minute to realize you mean Buss Speed.

Glue a 40mm fan onto the MCH/Northbridge heatsink, it gets OCed just like the cpu.

Forget that auto voltage crap.

Set your Vcore to 1.425 (promptly check your core temps on next boot into windows.)

Set your memory voltage to the high end of the manuf recommendations. Gskill in particular does not like to run at its rated 1.8V. Use 1.9V. Get some PC6400 memory when you can, its cheap enough now.

Set the MCH voltatage to +.2

All other voltages on default/auto (but since you have selected manual voltage control they should get set to default values even with Auto selected.)

Might find some more tips here: http://hardforum.com/showthread.php?t=1248435

Post back with max FSB and what the multi is (i too lazy to look it up) and the resulting cpu speed and idle and load temps witth the settings above.
 
Thanks for the reply Bill.

I can attach a 40mm fan to the NB, but I don't know how effective it will be. My HS/Fan covers more than half of the NB.

See image (crappy cell phone cam):

I went ahead and switched out the 800 rpm SFlex for a 1200rpm (I have a 1600 I can try as well).

Multiplier is 10x, gonna work on the voltage now and report back.

So after some testing (and many reboots) here is what I got stable:

MCH: +0.2
mem: +0.2
vcore: 1.475, 1.440, 1.408(bios, idle, load)
310mhtz BS(1240mhtz FSB), 22/56

After several attempts I couldn't get 315 BS (1260 FSB) stable. Kept giving me BSOD with stop 124. I'm guessing I'll have to push the memory higher, but I don't want to do that with these g.skills.

The temps all seem good, equal to stock HS/Fan @ 266 BS. When I tackle this again (after getting the new RAM) I'm gonna go ahead and flip the HS/Fan around so I can attach a fan to the NB. Will also put on the SFlex-F at the same time.

With all that said I'm gonna drop it back down to 300 BS since it was stable at much lower voltage.

What RAM would you suggest in the PC6400 range? I'm guessing something that's actually rated 2.0-2.2 voltage? Even though I'm testing with 2x1g at the moment I'm looking to have 4g total (4x1 or 2x2 doesn't matter to me) when all is said and done.
These look good:

Any others to suggest?

I'm also going to replace my PSU, I don't trust this Rosewill when it comes to OC'ing.

Any other advice, or words of wisdom would be appreciated.

Its quite possible that the chip just won't do much more than 3.0 - the 10x multiplier is a little bit limiting on those chips. 1.475 seems a little high for Vcore - isn't stock like 1.325 or something?

Also, I'd be suspicious of those temps - 22C idle with 1.475 seems too low - what is your room temp? What are you using to measure temps - I'd be inclined to think that you need to add the 15C adjustment to those temps, making your temps 37/71 and you are temp limited on your overclock.
 
Room temp is ~ 17-19 range. Using CoreTemp and SpeedFan to measure, they agree on the temps.

Right now on a 3.0 OC with vcore set to 1.425 and reported levels at 1.392/1.360 I'm getting 18/48.

Remember, this is a fairly big copper HS with a large fan (running the 1600 rpm SFlex at the moment), and a second large fan (also a 1600 rpm sflex) pulling air out of the case a few inches from it.

At stock speeds it's reporting 20/41 temps with the stock Alum HS/Fan. This seems about right based on other people's chips. Either most people's are reporting incorrectly (which is always possible), or they are all in the same low temp range.

I do think I'm hitting the wall with my particular chip, mobo, and/or ram and I haven't decided if I'm gonna replace the ram yet. Right now trying to see if my 4 gig setup (4x1g) is stable at 3.0ghtz. Will probably call it a day if it is. 50% OC on a $90 chip isn't bad at all.

Maybe you can explain the OC multiplier to me... I figured a higher multiplier would allow for a better OC since you can achieve better speeds with a lower FSB/BS. For example, I'm running 300x10 to get 3.0ghtz, if I had gone with a 2160 I would have to run 333x9 to get 3.0ghtz.

Anyway, thanks for everyone's help with this.

Click to expand...

A higher multiplier is better if you are FSB limited - if you can only get to 333 FSB then it would be better to have the 10x since you get a higher final speed (assuming the chip can handle it). Performance-wise it is better to have a lower multiplier and a higher FSB, if possible and within limits, because then your memory throughput is higher. I don't know that it is as much of a factor as it used to be though - not sure how memory limited C2D chips really are. Nowadays the northbridges can handle insanely high FSB speeds - upwards of 500 in some cases, so being FSB limited is usually not a problem, it is the chip limit that gets you - especially if you have a low FSB chip like the E4xxx series. The new 333FSB chips will require the high FSB for decent overclocking.
 
FWIW, I just finished a quick setup on a 2180 with a known good to 412 FSB/~850ddr2 MB/memory combo. Seemed like the CPU was limited around 310fsb causing reboots under Orthos. I left it at 300fsb for 3.0Ghz at 1.2875vcore and it's happy now.
 
Yeah, I've seen a couple of confirmed 3.3 OC's, and at least one confirmed 3.5, but this chip seems more limited than I originally thought, hovering in the 3.0 to 3.1 range for most people apparently.
