CPU throttling !!! quite urgent - Page 11

post #101 of 136
Thread Starter 
prime95 is good for stabilizing your CPU under most extreme circumstances.

and the thread says prime95 isn't optimized for FX processors, but that's not true the newer versions of prime95 fully adapt to CPU type before stress.

look at my screenshots, the first sentence says adjusting to bulldozer architecture, or something along those lines.

however, what i'm trying to get through is that your real world tasks don't quite work the same way as a synthetic benchmark.

After some test on my side i trust p95 i just got a bad chip p95 wont fail 1.4v 4.4ghz until now mad.gif

4.4 ?! for me i had to go to 1.44 to have a stable 4.4 oc

but yours a 6300, try 1.42
post #104 of 136
p95 blend test for 1 hour now on 1.4v with very high llc so voltage is 1.392volt on idle and 1.404 under load


Blend always fail while small ftt pass 12 hour + even at 4.5 ghz when blend fail in 5 10 minute at 4.5



I have a good chip but the 5 core is the problem and even at 1.55volt i cant run at 5.0ghz

Tried 1.5 4.8 and fail too..


Will try 1.5 with high llc next day at 4.8


But anyways at 4.4 im near a i5-i7 in most bench even beat them in some...

The only advantage they have is they can overclock too and have less core

i think the best is the lower we can get

1.3volt 4.0ghz 1.4v 4.4 if it stable im pretty happy smile.gif

If blend fails could that be a sign of RAM instability?
post #106 of 136
uh did not think of that ways but i have 1 kit of xms3 4gb and one value 2gb both 1333 cl9


Hum will see im now at 4.4 1.41 volt it failed at 1.4


Thank you i heard bad story about xms3 anyways

Run memtest on it for a least a couple of passes.

Very true. Ive noticed the AMD stability test exercises some different areas than prime, so its also a test to run in addition to prime and IBT AVX.

like those ceramic solid state capacitors, they're usually rated for 230-260 safe to a max of 360c.

resistors "Typical maximum temperatures for carbon composition resistors would be around 100 to 120°C and for metal and oxide film types, about 150°C. Wirewound resistors can operate at higher temperatures up to around 300°C"

couldn't find specific values for mosfets. (same with diodes)
they very depend on the type and use. higher temps simply mean lower efficiency.
________________________________________

more research shows that typical motherboard mosfets are stable at 130c. yet they can go up to 150c apparently. (130 sounds better thumb.gif)

don't get VRM mixed up with mosfet, VRM is a module, a whole set of different components make a module.

mosfet is what's under the heat-sink.
it is all well and good that certain components can handle temps like that. But that won't stop the software in the BIOS from throttling your chip at a certain point. Also you can't ignore the laws of physics. It's wonderful that these mosfets can handle 150C. But what is the point when your solder on your motherboard starts to MELT at 135C? I thought so.... Guys I give up on this thread. I've HANDED the solution to your problems on a golden plate. If you don't choose to listen then that is your problem and your choice. But don't go blame brands such as AMD and ASUS for poor quality components because you weren't willing to listen to the solutions to your problems. When you do decide you ACTUALLY really want to fix the problem you can contact me for word on fans to use for your VRM's and socket. See ya

ahaha c'mon chill bro.

1st of all the solder on your motherboard doesn't melt at 135c, don't believe me ? try it for yoursellf, get a soldering station and heat it up to 140c ...
there are different type of solder, some even melt at room temperature.
refer to this list for more information on different alloys :
http://en.wikipedia.org/wiki/Solder#Solder_alloys

the melting temps for the kinda solder used on PSBs is over 210c.
they have a pool of molten solder, then they swype each board over the pool for a fraction of a second, that does it.
for smaller parts on the board like those tiny diodes, they use robotic arms and machines as far as i know.

anyway the point is that you don't need to worry alot about the 100c on your mosfets etc..

just keep your CPU cool, everything else will be fine.

and for those who want a stable overclock, at 4.4 4.5

like i said before, just give the motherboard a bit of head room. these FX chips draw alot of power. maintaining the same voltage and amp puts a lot of pressure on the voltage regulation module on the board. specially because the m5a99fx pro r2 is 6+2(+2) phase design. 6 for the FX processor 2 for the 990 chipset and 2 for your RAM.

to push these CPUs really hard you need a certified power supply that can maintain the 12v rain voltage under load. and of course a board with more phase design. e.g. sabertooth 990fx

*by giving the mobo a bit of headroom i meant, drop all the Digi+ settings to their minimum and instead increase the CPU Vcore and VDDA (if you have to). this way the Voltage regulation module has more room to stretch its arms and legs if it needs to.

power (w) = current (apms) x potential difference (volts) .... this means that when the V goes down under load instead the Amps increase to provide the same power to the CPU, meanwhile when ur CPU is sitting Idle the Amps drop.

to add to your general knowledge:
*voltage is the energy transferred per unit charge(coulomb) *1.6 × 10^-19 is the charge of an electron*, in most cases charge carrier is an electron but it could be other things like an Ion.
*and amps are basically the number of charge carriers (electrons) per second.

*if you don't know what VDDA is check this link:
