My system is in my signature.
At idle, both cores report the same temperature +/- 1 degree and are close to MBM-5 (after adding 10C as an offset in the BIOS -- known problem for early DFI expert MBs).
BUT, when I load prime05 in both cores, one reports 55C and the other soars to 75C! (MBM-5 only goes up to 50C).
When I load 2 copies of super-pi the cooler core reports a little lower (52C) and the other core is _only_ 67C.
How can I have a difference that big when both cores are on the same die so close together? OR, does that explain why core 1 (you call it 2) is the weak core.
QuietIce said:Yeah, I have a small problem with Core 1 & 2 also - should be core 0 & 1. Eh.
There are some strange results for me, though. Using Prime95 I have the following results (core 0/core 1):
idle - 29/19 (not a surprise since core 0 is the first to fail Prime95)
Prime95/core 0 - 30/25
Prime95/core 1 - 53/29
2x Prime95 - 53/35
It looks like the single runs are reversed or something - weird. But I did double-check the affinity setting and it's right so I don't know what to think. Prime95's affinity setting not as good as first thought?
Also, the VID is showing 1.325v instead of 1.525v - I assume you're reading that off the MB? To go above 1.45v on this MB you have to use a "boost" setting in the BIOS, which adds 0.2v to the VID setting. If that's the real volts as read by the CPU then this chip is a wonder running 2.8 GHz at 1.325v!
It is a great program - definitely pointing out the limiter.The Coolest said:Well Core Temp doesn't use affinity to select a core, its done by writing to special registers in the CPU's IMC.
Regarding VID, its read from the CPU itself, thus on the CPU the vid setting is 1.325v, but the mobo adds the extra 0.2v via the boost option.
Idle: both 34CThe Coolest said:I would suggest you test what QuietIce has done (#31).
Both idle, load core0\idle core1, idle core0\load core1.
So, since I set my VID to 1.35V, you show 1.35V. But since you can't see the VID Special of 119.2%, you don't know that it's increased by 19.2%?The Coolest said:Well Core Temp doesn't use affinity to select a core, its done by writing to special registers in the CPU's IMC.

Read the two last quotes by me in this post:davidk21770 said:Idle: both 34C
Prime 0: 51/48
Prime 1: 74/51
Prime Both: 75/55
SuperPi Single: 60/50
SuperPi Dual: 65/53
Killed 1st SuperPi: 60/50
(Only about 30-60 seconds each -- not long runs).

V-CPU 1.609V
2761 MHz (Was stable at 2808, but I've needed to reduce this -- why I'm really interested in the accuracy of the readings)
Danger Den Liquid Cooling
NOW -- what does this mean? That core 1 is running big time hot? And, why doesn't this agree with the BIOS which is supposedly using temperature diodes on the CPU also?
AND -- is there any way to balance? Ie., is it the heat spreader or just that one core runs really hot and there's nothing to be done?
