2180 oc question

[Build it Myself]

I posted this in the how to oc thread, but it's been a couple hrs. without a response...and i suppose it could use it's own thread anyway, so here's the original post:

I have a question because i'm having a problem with my overclock. i'm running what you see in the sig, 2.76 oc on a 2180 with an ip35pro board. it's orthos stable and runs all my apps and games @ 1.3350v. I tried oc'ing to 3ghz and had to up my volts to 1.4050 just to boot into window, and even then orthos crashes in 3seconds and i can't have more than 2 internet browsers open @ a time. Speedfan shows vcore (when @ 1.4050) to be 1.54, temperatures seem ok, but then again i can't load it so i don't know).

My point is that the voltage seems really high to me, however i'd like to see someone else's opinion, maybe i'm just being paranoid. I don't want to blow this chip since i don't plan on getting another one until Q1 2008.

Is 1.4050 too much for a 2180 or can I push it more? I'd like to have a 3ghz oc, that's the reason i went with this chip (higher multi than 2160/40). It's not my ram since i've got the timing relaxed to 5 5 5 5 15 and it's running 1:1 @ 300fsb (600) so that's not the problem.

Can I push the voltage more, or should i be pushing in a different direction. The abit BIOS interface is different than what I studied on, so the uGuru seems a little strange than doing everything manually. but regardless, is there another voltage i should be looking at? am i missing something?

Thanks,

John

bump? strange nobody's replied yet...

i had to go 1.465 to get 3.15ghz out of my 2180, it's on a ip35-e
my core temp topped at 56C with 2 hours of orthos

1.465 is barely over 10% VID, which is way within safe IMO
It's definitely a safe vcore if you have only until Q1 2008 to go !

I would say if you don't intend the CPU to last FOREVER, then a 10% over VID 24/7 is not a problem
Or, if when you upgrade your cpu and want to sell this one, and you want to be able to clam that the chip was never run over 1.35 then it's looking like sub-3Ghz. But, I'd say that that speed for that vcore is not out of the ordinary.

this thread is where you want to ask any further questions about your setup

thank you, that's all i really needed to know, i just don't want to push it too far, and i don't know where "too far" is. I'm not gonna resell it anyway, i'm gonna put it in my parents computer when i upgrade to replace their 3.4ghz p4.

Thanks, i'll go clock this up right now

These E2180s seem to need more vcore as you increase the overclock. I have a 2180 on a IP35-E and it needs 1.52 to run at 9 X 370 stable.....

My E2140 only needed 1.425v to reach 3.28Ghz stable. Load temps are 66C according to CoreTemp.

Now that's just rubbing it in Larry!!

Consider yourself lucky you broke 400 FSB. Many of the E2XXX series top out anywhere around 370 - 380 FSB.

1/2 should hit 3.2GHz. Same with E4xx0 chips. These 800MHz chips are limited to about 425MHz FSB.

 

[Tempered81]

my 4300 hit 3.28 on 1.38 vcore. its either a bummy chip that doesnt want to oc much - to the OP, or you can try going thru an abit mobo overclocking guide, perhaps thers a certain bios option that should be enabled/disabled.

Wee you learn something everyday. I was wondering why moving from E2160 to E4500 still could not get beyond 417 on th GADS3L - now I know.
To OP I run at 1.44v everyday use and I figure by next summer I am probably going to change to something else so I run close to max all the time.

Thanks everyone, i'm running 3ghz gaming stable (orthos doesn't like me much) at 1.4450, i figure that's all i wanted out of this chip anyway, so thanks a lot for the help. I don't know why the orthos fails, but it runs all my apps fine so that is what i really care about. Under orthos, temps peak @ 54C before it inevitably fails, so I think i'm within reason. If i ever have a problem with Crysis or what have you I suppose I could go up a hair in Voltage.

Thanks again!

Raise your NB voltage a notch or two. 4 GB is a hard overclock, no matter what anyone tells you, and almost always requires higher NB voltage (and usually also higher vdimm), unless it's two 2GB sticks.

 

[Build it Myself]

it's 4x1gig, and honestly, i don't know where to locate the northbridge voltage controls at. Like mentioned, the abit uGuru interface is so "simplified" that I think it's complicated

You wouldn't happen to be familiar with the other coinings NB might have, do you? Or other words they might use?

I needed ~1.475V in bios to get my E2180 Orthos stable at 3.2GHz. That's with 4x1GB sticks in an IP35-E.

Not always. I was running 4x1GB SuperTalent DDR2-667, at 410Mhz (DDR2-820), at 4-4-4-12 and I didn't see any additional errors. (There was one reproducable error, which also occured at stock timings and voltage, obviously a bad spot on the chip.) I did have vdimm at 2.0v though.

Quality HP/Crucial RAMs should run well at default NB/SB with four modules. The problem RAMs are OCZ.

Your baseless accusations will never stop.

The OCZ chips are the same ones used in the HP/Crucial rams as you have said in other posts. "They just slap heatspreaders on and charge more." Now you are saying they miraculously use some other chips that make them need more NB/SB voltage.

When will your smear campaign end?

Please say soon because I am completely tired of your ranting and raving.

IT DOES NOT MATTER WHAT BRAND OF RAM YOU RUN. WITH OLDER CHIPSETS THAT WERE NOT DESIGNED WITH 4x1GB by USERS IN MIND, YOU MAY NEED TO INCREASE NB VOLTAGE TO GET YOUR DIMMS STABLE.
