e2180 overclocking

[wingnuttzz]

hi guys

been trying to overclock my e2180, and have been with great results

my system is as below
e2180
evga 680i
patriot 4gb ram
zalman 9700-nt

i've got it completly stable at 3.4ghz @ 1.45v's in the bios (idle's at about 45, load at about 77)

the thing is, i can't seem to get it to run at 3.6ghz. i've been all the way up to 1.625v's in the bios, and i tried upping the CPU FSB voltage and the Nvidia SSP and MCP volts with no avail.
It can boot into windows, load everything, but as soon as i try to run orthos, as soon as i click start, it crashes and last-time it jsut shut the pc down. (thermal cut kicking in??)
admitly, it was idling about 70, but surely its fine for a cpu to hit nearly 100 in orthos, as in real life situation, u will nvr stress d cpu like tht.

i have since gone back to my 3.4ghz set-up, but really want to push this CPU further, lol.

have i reached the limit of the CPU, or is my cooling my limits??

and what do you guys run your e2180's at and at what volts etc

thanks

seems these cpu's can be a hit or a miss, whether you get a good overclocker or not.

tbh, i'm not very happy with my current load temp of 77, but the way i see it is that in a normal situation (gaming etc), you are never going to stress the cpu the same way orthos does, and i am yet to go over 60 i think in normal situations, so i'm happy with my temps atm.

i'm guessing OP stands for Original Poster (a.k.a me)

i've just rebuilt my PC (new PSU being fitted) and in doing so, i desided to re-sit my cooler (zalman 9700NT) as my temp's did seem to be rather higher. While rebuilding, i also fitted another 120mm fan to the front of my case directly in line with the cooler as from what i could figure out, my cooler was actually getting no benifit from my front HHD cooling fan as the graphics card practically cut the case in 2, lol.

just ran Orthos again, and my max load temp is much much better now, 65 degree's
idling at around 42..ish

just goes go's to show how a badly applied cooler and bad case cooling can affect your tempertures

Am i right in assuming these temps are now good and safe??

Going to play around with my voltages later aswell, see how far i can drop them and keep them the system stable (it wasn't stable at 1.4v's, and its perfectly stable at 1.45v's, i haven't looked at anything in between) so maybe i might get another temp drop

thanks

That's much more like it. What's the vdroop like on your board? If you load up cpu-z it will tell you the voltage. Take that away from what you set in bios and you have vdroop. Sort of like that anyway.

yay

my motherboard (Evga 680i) suffers quite a lot from v-droop.
At idle in CPU-Z the core voltage is 1.424v's
under load (orthos) though this drops to 1.400v's

remember i'm reading 1.45v's in the bios

i did a bit of reading about the pencil trick on my board, so i might try it, as the difference between the BIOS and in windows doesn't really bother me, its the volt's dropping off under load that is the problem, as you have to conpensate for that, which means you are over-volting at idle.
