E2180 Overclocked

[jeffconnors]

I have oc'd my new system to 270 and DRAM speed to 1:1.50. I"m new to this so I'm not sure if there is anything else to do? Will this run faster and still be safe? I have the E2180 with Rosewill fan, IP35-E Abit MB, Corsair 2GB 800 memory, Vista. I loaded CPU-Z and Prime95. Prime has passed after about 2 hours. Any help would be appreciated.

Faster, yeah, most likely. Safe, can't say. How do your voltages and temps look?

Use Speedfan to check your temps and CPU-Z to test your voltages. Report back and we'll go from there. I'm curious to see what my 2180 will do but I'm cursed with a crap PSU until I can order another one over the weekend.

Note to beginner DIY PC builders: Don't skimp on a PSU if you want to push your PC harder .... from OC'ing to multiple HDs or optical drives, just buy a quality PSU and go from there.

Some people will say that Prime95 for two hours is good enough to declare your system stable, since they don't plan to do anything that stressful for two hours straight.

Other people will run Prime95 overnight or even for 24 hours before they consider an overclock stable.

Personally, I'm in the overnight camp.

I'm on overnight, too. I frequently do large batches of video encoding and that kinda requires several days at full load. Heck, if I didn't need the PC, I'd do a 24/7 stress test.

I run orthos and memtest overnight a few times over the course of a month or so. Sometimes I run OCCT overnight with a custom 12 hour run. So far, with my E2180, no hitches at all to report.

Core Voltage is 1.160V
Temps are 21C both.

What about under load? That sounds like voltages and temperatures at idle with C1E and EIST enabled. Run orthos for a few minutes and then let us know what cpuz and coretemp show for volts and temps.

You are right! I have Prime95 and just started it, is that okay?

 

[jeffconnors]

1.152V
36 C both

Prime95 (small FFT's) ........for 45 minutes, both the voltage and temp have remained the same the entire period.

How does the voltage and temps look? I'm wondering if this E2180 can be OC'd more?

 

[cubeless]

running orthos? need to get both cores going... 36c is way cool... u should certainly b able to push further...

I ran Prime95. Is orthos a better stress program? I thought Prime would stress both cores. If I OC further, do the RAM timings need to be changed?

iPrime 95 will work but, you have to open two sessions of it and manually set them to run one on core 0 and the other on core 1. Ram timings only need to be changed if you change ram speed. right now at 270*1.5=405*x=810 so if it's DDR2-800 and you want to go higher without changing the ram divider then yes, you'll probably have to relax timings and/or bump voltage.

 

[jeffconnors]

I'll run Orthos and report back tonight. Thanks

 

[nerp]

Yeah, Orthos is the way to go. It will run Prime95 on each core in a nice concise box. No crazy configuration to mess with etc.

Run the Small FFT test to gauge maximum heat under load. For total system stability, run the blend test.

I ran Orthos in both settings for about 45 min each, all passed. The CPU was 1.152V in both. The cores were 35-36C. Th DRAM is 4.5MHz; FSB: 2:3; 5/5/5/18. What would you recommend the OC settings be?

What heatsink are you using?

Rosewill RCX-Z775-LX from newegg

 

[hooflung]

I would say you would be able to get a 2180 at 3ghz using a 300mhz fsb. You might have to increase your voltage up 1 notch if it doesn't run stable. My e4300 ( similar to the e2160 ) runs at 333mhz x 9 just using 1.45v. Been using it for 3-4 months at this setting. Did 300 x 9 at stock for 6-7 months before that.

 

[DerwenArtos12]

Wow, your ambients must be about 14C for those kinds of load temps. I'd say go nuts, crank this sucker up till your loads get to about 50C so long aas you keep voltage at or under 1.475v and see what you can squeeze out of her.

Well, new PSU hasn't shown up yet, so I left the Ultra 500 PSU in there and hit 3.0 ghz with no voltage bumps at all. Speedfan reads the +12 voltage at a steady 11.4 (yikes !!) but I was surprised that it was stable. Tried a newer version of Speedfan under the assumption that it wasn't reading voltages correctly, but 4.33 reads the same. I know its not ideal to run it that low, but so far I'm impressed with this chip for $50 AR.
A friend's 4300 rig that I built couldn't hit 2.8 stable, and he had a Gigabyte 965 DS3 board that smokes my Asrock 775. Overclocking truly is a luck of the draw thing tho.
