Free performance is always a blast. I don't think we'll ever get bang-per-buck like the Stars core unlocks again. Kind of a shame but hey, enjoy that little slice of history while it remains relevant.

we had the pesky '64 bit can't clock as high' on the C2 stepping. I wouldn't say it was the best bang-per-buck by any means

Must have been mobo temp sensors. Athlon II / Phenom II CPUs, after unlocking cores, can't have their internal thermal diodes read for some reason.

no, the socket diode isn't a thermistor and doesn't track with CPU temp instantaneously seeing as it's on the motherboard, below the CPU die, thermally insulated by the air.

Yeah 3.4 is just it's stock speed.

I will try to go higher later on.

If the TDP is anywhere near as high as reported, there's no way it can be kept cool on air.

Nothing I've tried gives any CPU temps except HW Info with TMPIN0 and 1, neither of which appears to be what I need to know.

Having said that, the cooler that was on it was not very big, and it still never showed any signs of instability. It never throttled during a stress test with the smaller cooler.

I'm beginning to think it isn't anywhere near the reported TDP and it isn't getting very hot at all.

Well that's not really the point . . . whenever you can snag a cheap legacy dual core product and turn it into a quad, you're basically doubling your computing power for nothing. There aren't many 100% overclocks out there anymore.

Besides, even c2 could hit 3.7 ghz pretty often under a 64-bit OS.

Yeah I know my mobo still throws temps that seem useable, but from what Ive read the temps you get should only be taken with a grain of salt. Unlocking the chip apparently affects the most accurate temp sensors.

I'm sorry I stupid I meant to say 3.8ghz IMHO or more then it's worth it

if it's C3 you should be fine.
does it have any heat pipes? post pic of the cooler and I can provide feedback. the $30 120mm 212 is fine for it and should make 3.8ghz possible with a 45+cfm fan. I have a 120cfm fan and never needed more than 45% at 4ghz and 1.4375? 1.475? v on the 965 I had to maintain stability and under 63C. the c2 720be->x4 unlock at 3.5ghz/1.47v and 2.6ghz CPU-NB could go up to 70C with stability but the second I jumped over 3.5ghz AND 63C would fail immediately. it was weird, but I was happy. Maintaining quiet PC was priority for me so I left it at 3.5 and moved on

yeah, i guess you're right

I watched all the temps in speedfan and became acquainted with how the CPU heated up at stock. from tehre I unlocked at stock frequency but OC voltage and watched the temps, and found one that was responding instantaneously (unlike the motherboard one-- which you can label in speedfan and won't change with the unlocking)

oddly speedfan was like the only one that gave me the temp. coretemp and overdrive didn't

it might matter which mobo you have. I have used gigabyte exclusively for quite some time.

The computer is at work, so I won't mess with it again until Monday.

Let me try Speedfan then, and see if I can get a useful temperature reading.

Right now it has an Arctic Alpine 64 Pro Rev. 2 on it.

It originally had a much smaller stock AMD cooler on it.

1A02C3W00, which is ridiculously rated for up to 100W TDP, higher than the Arctic Alpine cooler.
 
oh. you'll probably still need more than that for cooler. once you hit the thermal limit on the heatsink you'll see the temps just run away from you.*

you can use PhenomMSRTweaker for nicer CnQ states.

*170-190 is the limit on my thermalright ultra-120. I always wondered why temps just exploded after 1.475v and 3.5ghz at 2.6ghz cpu-nb @ 1.4v on a c2-stepping Ph2; and at 4ghz at 1.44v at 2.6ghz cpu-nb @ 1.3v on the c3 stepping 965 I had. I noticed similar runaway immediately after 4.3ghz and 1.35v on my FX-8310, and finally saw a graph comparison of total system TDP with FX overclocking all the way up to 5ghz-- after 4.3ghz (surprise surprise, CPU component was about 175w there) the speed vs. power curve bifurcated on up to like 275w for the CPU alone just to get to 4.7ghz. To handle 4.5ghz I had to set my 120CFM fan to 100% and even that only barely kept temps 'safe'. Between that and these graphs that I saw a couple months ago comparing the OC and power usage potential was when I learned for the first time that "thermal capacity of heatsinks, heatpipes, and wicks is no joke"

Speedfan adds a single core temp reading, but it stays at 0.

So I still cannot get a core temp with the extra cores unlocked.

is it configured as a thermistor or diode in advanced tab? should be thermistor, and most likely is.

that's too bad then, sorry. perhaps I was just lucky on mine
 
Okay, with Speedfan I have:

Temp1
Temp2
Temp3
HD0
HD1
CPU
MB
Core

Temp1 and CPU move sluggishly and in lockstep. That is the CPU package or case temp, I believe.

Temp2 and MB move hardly at all, but in lockstep. That is the motherboard sensor, I believe.

Temp 3 goes to -70C if set to diode, and 127C if set to thermistor. It never budges from either number.

Core stays at 0C.

When running a heavy stress test:
Temp1 and CPU start at 34c and very gradually reach 56C after about 5 minutes.
Temp2 and MB start at 32C and reach 34C in that same 5 minutes.

Temp 3 and core remain the same all the time.

I have a front and back fan and good airflow through the case.
 
Case temp on the CPU would respond immediately. this has me thinking it's the cpu-socket temp, and Temp2 being somewhere else on the mobo.

if it makes you feel safe, my socket temp is never more than 15C behind the CPU temp


I think Temp 3 or Core is what we needed.

honestly, you could probably safely hack your way through the fan speeds by using the cpu-socket temp. LOL. never thought of this before, but I would personally be willing to try it given how closely related they are on my FX
 
sorry, my cpu-socket is usually a bit hotter than the cpu itself, because the cpu has the heatsink above it to dissipate the heat. never more than like 15C though. but that might be because the fan on the cpu heatsink kicks in
