I have the Verizon Extended Warranty if anything happens take it back to my friend who works there no ?'s asked and bam new phone I have mine at 800 mhzWell, there's this:So, you were doing more than simply providing information, you were telling people that the information should somehow ease any concerns they might have about overclocking and heat.For those of you worried about overclocking put your minds at ease...nuff said.
What I pointed out was that the information you provided didn't apply to the Droid, so any such claims based on it were meaningless. Which is correct.
How do you know that's the junction temperature (which is what the datasheet refers to)? All the temp apps I've seen use the AK8973 sensor, which is thermally remote from the OMAP3430 substrate. Without knowing the thermal design, the only valid assumption is that the measured temp moves in the same direction as the average processor temp (as long as the ambient temperature is constant).
Even if one did know the exact relationship between average processor temperature and the sensed temperature, the processor itself has 9 independent voltage domains. It's entirely possible (for example), that the processor is overclocked and getting too hot, while the rest of the chip is not, so the average temperature appears OK. The only way to be reasonably sure is to measure the current for each of the supplies. TI provides a table showing maximum current draws for exactly that reason.
If that is the case, then this too would apply (from the datasheet):I think it's a valid assumption that the operating temps are similar and not dramatically different.Clearly, TI's concern is that damage is cumulative - the more you run it, and the higher the temperature and/or frequency, the shorter the expected lifetime. It appears that running the processor at 600MHz (OPP5) "burns it up" about twice as fast as running it at 550MHz (OPP4). Even higher overclocking likely accelerates this further.To avoid significant device degradation for commercial temperature OMAP3530/OMAP3525 devices (0°C
<= Tj <= 90°C), the device power-on hours (POH) must be limited to one of the following:
· 100K total POH when operating across all OPPs and keeping the time spent at OPP5-OPP6 to less
than 23K POH.
· 50K total POH when operating at OPP5 - OPP6.
· 44K total POH with no restrictions to the proportion of these POH at operating points OPP1 - OPP6.
To avoid significant device degradation for extended temperature OMAP3530A/OMAP3525A devices
(-40°C <= Tj <= 105°C), the following restrictions apply:
· OPP5 and OPP6 are not supported.*
· The total device POH must be limited to less than 50K.*
*If an extended temperature device is operated such that Tj never exceeds 90C (-40°C <=Tj <= 90°C) then
the OPP POH limits for commercial devices indicated above apply.
IOW, overclocking will damage your Droid. Probably not quickly or catastrophically, but it should be expected to shorten it's lifetime.
"OPP5-6" refers to the core/processor supply voltage. There are lots of claims that the Droid is underclocked @550MHz, and TI specs it for 600MHz. Again, making the (possibly invalid) assumption that the Droid has the same specs as the OPA3530, we find that the actual TI spec is 550MHz @ OPP4. 600MHz requires OPP5, which is simply not supported at junction temperatures above 90C (see above). It's not clear exactly what changes the people building overclocking kernels are making - these may not change OPP, and hence be putting the processor into an unsupported area (which is almost definitely the case for any overclocking beyond 600MHz).
