Oi lads, sorry to be a pain but I wonder if I can make a technical request?

Can any E7200 owner please do some undervolting tests? I'm keen to know what voltages these new chips can run at using low vCore?

Thanks! :)
 
ManCuBus, what are you reading temps with?

Coretemp reads 10c higher than Realtemp, they are obviously using a different TJmax.

My gut feeling is that Realtemp is more likely to be right because the temps in coretemp at stock speeds seemed high and it doesn't report the details correctly.

Have I read somewhere that there were some incompatibility issues with coretemp and wolfdales?

Its the wolfdale temp sensors mate, they are all over the place and they sometimes post crazy temps. I dunno what to believe to be honest.

Below is @ 3.6, 1.27v. Working my back up to 4ghz after my raid config decided it was having a coronary.

As you can see none of em match.
 
Just had a quick play;

366FSB 3470Mhz at stock volts (showing 1.168 in CPUZ)
411FSB 3900Mhz at 1.385v (showing 1.34 in CPUZ)
423FSB 4000Mhz at 1.4v boots but fails to get into windows

Don't really fancy more than 1.4v so will probably try a few more settings between 366 and 411 and may stick at 3.5 at stock volts for 24/7 use, can't really complain at that.
 
Right then, gonna run orthos overnight @3.8ghz with 1.384vcore. If that passes ok I think I'll stck with that.

The voltage increase I needed for 4ghz would need a better W/C system than mine to be ok 24/7 I reckon. :(

Then in the morning I'll do Big.Wayne's undervolting test.
 
1.1 is the lowest vcore available in my bios so i can't try any lower than that (1.072 loaded).
I guess you would get a lower vcore if you disabled the load line calibration.
Only ran orthos for a short while but it seemed nice and stable. I was watching live tv in VMC while this test was running and it never stuttered at all. That's probably because my GTS handles all of the video although VMC records on the fly so it's still really good.
Ignore the right hand temp reading. There seems to be something wrong with that sensor as it didn't move from the idle temp.

Currently testing 3.8 with a lower vcore (1.344 load). Seems ok so far, runs a few degrees cooler too. :cool:

I don't think that there's any available at that price now chap. :(

Mine arrived yesterday so gonna have a play tonight hopefully.

Close th ough... just ordered mine at £83.88 delivered =)

Mine'll be going into a p5k-vm, along with some pc8000 g-skill, so 3.8ghz+ should hopefully be possible... gonna chuck it under water too btw.
