E2180 OC help

James J · 3 Jan 2008 at 20:05

Got the following hardware

E2180 with Artic Cooler pro 7 on it
3gb GEIL 800mhz 4-4-4-12 ULL ram
Jetway 8800GT
250gb WD HDD

Highest my cpu will go is 2.66Ghz atm due to games crashing if I go higher

Currently at 1.4v core, 1.23 CPU VTT 1.37v MCH

temps are really good though still lol

What can I do to go higher?

Up the voltages and try again.

James J · 3 Jan 2008 at 20:22

whats a safe stop margin on the E2180 chips for voltages?

Im at 3ghz with mine 8 X 375 with an Arctic Freezer Pro 7 60oC underload. I also have the Geil Ram. Try loosening the timings to 5-5-5-18.

Ive got one running at 3.3 with 1.45V topping out at 65C during a 24 hours Orthos run.
330x10 1:1 2x2gig OCZ pc5400, AC pro 7. 17 Second SuperPi. Vista 32bit.
Encodes DVD's quicker than my rig in sig.

Trying for 300x10 atm on 1.44v, also reseated all my ram and given everything a good clean and im into windows now. Need to test stability ofc.

edit abit EQ is reporting 1.38v CPU voltage under load whilst my MCH voltage is spot on. Is this a good example of undervolting?

Ram is also 2.06v instead of 2.1 and im running 4 sticks of it atm

Ouch that's quite a vdroop.
Recent E2180's haven't been clocking too well at all.

Games wont start at 300x10 with 1.44v in bios, trying 1.46 and seeing what windows says the cpu is at

Dang, even my L2 E2160 clocks better than that. Dunno what's going on with those 2180's.

James J · 3 Jan 2008 at 20:53

1.46v boots and says its giving 1.44 in windows but got corruption on UT3 opening videos so backed it off

Trying 2.8ghz (280x10) with 1.38v and 1.2750 VTT

James J · 3 Jan 2008 at 21:01

well got no chance of even 2.8 stable, looks like I got abit of a poor chip overclocking wise. Might as well start saving for a decent stock quad lol

pegasus1 · 3 Jan 2008 at 23:19

There must be more to it than assuming its a dodgy chip, what temps are you getting at 1.45V ? Its possible to get .5v VDroop with some mobo's.

uv · 4 Jan 2008 at 00:02

My board says that the vcore is 1.5, tho speedfan reports it as 1.42, and the temps report accordingly. An insane vdroop, but as said earlier, just up the vcore in bios

you'll know you've got too much volts when your cpu loads 60+

just priming mine at 3.4, 1.42vcore (1.5 in bios) - not too shabby these chips!

what mobo do you have?
*edit* and what psu do you have? crashing when playing games can be a power draw issue..

IP35 (abit) normal model and a corsair 520W modular PSU which delivers 40A per 12v rail

If you are running the ram at too low a speed that can cause problems. If you are using the wrong range of FSB strap, again, that can cause problems.

Munkeh · 4 Jan 2008 at 23:17

Try locking the PCI-E frequency out at 100. Also what is your ram multi set at? Try fixing it at 1 (or 2 if your on a GB mobo)

please explain what you mean by what you say here. Ive always kept the RAM BELOW 800 MHZ when trying the overclocks, that what you mean?

its locked at 100 by default mate

Hey mate
I understand the strap but im lost on the 'RAM to low' thing, unless you mean realy low.

weescott · 5 Jan 2008 at 00:10

800FSB chips - use the 200/266 strap
1066FSB chips - use the 333/400 strap

eg. If u can use a 347 CPU on a Gigabyte X38 board, my guess is that 200fsb will be the best. For the Q9550 the 333 strap was best, for the QX9650 the 400 strap was best. A lot depends on the board and bios though: I.E...errr...what works.

I found that running too low a strap or divider/ram speed just would't work in some situations. It could have just been the bios I was using at the time, but I tried a few and came to the same conclusion.
