speedfan says voltage is very different between cores

[cubeless]

dropped a x23800 toledo in the kid's lanparty... it has had a number of single core chips in it and all the parts are (were) good up to 300 fsb...

drop in a 3800 x2 and the chip don't oc too well... odd thing is that speedfan says that core 1 is @1.49 (i set to 1.5 in bios) and core 2 is @ 1.17... and it's core 2 that fails every time... core 1 is merrily running along...

is it the mobo screwing up the voltages? or speedfan not reporting right?

Mine showed as being different voltage too. What stepping did you get on your 3800+ X2?

ccbwe 0632...

very odd chip... it doesn't seem to like to run with a memory divider... it looks fine @2.4 @1:1, but wouldn't run @2.4 @ the 166 divider... the surprising thing is that with this chip my ram is running fine @ 240... with my 4000 it needed a divider because it wouldn't do 1:1 over about 112... weird...

i did update the bios on my dfi nf4 lanparty... maybe that's why the memory behaves better???

I had a odd problem with my Opteron 165 and a MSI board. I can run 100, 166 dividers, but 133 won't work with my Corsair or Ultra ram. 100,133, 166 dividers will work with my PQI ram

"Vcore 2" is not the amount of vcore that your second core is receiving. All cores in a processor receive same voltage. With SpeedFan, vcore 2 is what voltage your northbridge chipset is receiving. Also, core #1 (the second core; core #0 is the primary) always, always, always fails first. That's as normal as can be. And since you have a DFI, just use the 180 Mhz divider, since you aren't going to get that RAM anywhere near 240 Mhz, using the 180 Mhz divider and an X2 3800.

that's the funky thing... i'm @245 stable now... and this is cheeporam...

and a 'thanks' and 'doh!' on the vcore 2 number...

I knew that, I was just testing you guys...

In case you were wondering, here's what all of the temps stand for, on a DFI Ultra-D: link. They should be the same for your board, even if it isn't an Ultra-D.
