what is the lowest cpu voltage and the highest?

what is the voltage when idle (zero load in windows)?
what is the voltage when 100% load (prime95)?

Lowest is 0.984V
Highest 1.416V

Idle .0984 (Maybe lower)
100% 1.386 - 1.413

CPU fan almost silent its my outtake on the side with the honeycomb mesh (Completely Off topic)


~~~UPDATE~~~

Prime95 no errors after 1.5 hours. Turn up to 4.2 - 4.3 stay?

what multi is it set now? if youre happy I would set it to 4.3 and test, and how are the temps?

with those voltages I feel you have a power saving device enabled.

in bios turn off - cool and quiet, ce6 or ce1? something.

when in desktop idle the voltage should remain constant and not drop to 0.984, when it drops that low its because its a power saving/cooling feature. these sometimes make overclocks unstable or not perform as you want it to.

once you tested an learnt about that, you can be prepared to learn a lot more thumb.gif

Multiplier is @ x20.5 4100GHz

Cool 'N Quiet is off in BIOS, cant find ce6 or ce1

Temps:
CPU Max 42C
CPU Lowest 5C
Right Now, DURING Prime95 test 41C

I am going to turn it up to 4.3 tonight, are there any certain voltages I need?

in bios there should be a setting called CE** make sure its disabled. also you make have a setting called 'turbo' again make sure that's disabled.

that lowest cpu temperature is due to the setting you cant find being active. usually on a stock cooler itll settle about 30* idle without those settings.

yes I would increase it to 21.5 x 20 4.3ghz and let it run.

I would search for a cpu cooler that fits am3+ depending on your budget etc.

in hwinfo there is a couple cpu temperatures? one will be higher than the other, one will change a lot. these are different chip sensors. keep an eye on the highest. make sure that stays under 60*c

as for voltages, I think you have found a good voltage that will deliver the overclock you want. temps seem to be good, and so far its stable.

once you've tested prime for a while do a lot of tasks at once, maybe try another cpu stress test. really push it and monitor temps and for anything that doesn't feel right.

question: in hwinfo while prime is running, you should see frequencies core clock1,2,3,4.
do all these stay at about 4300mhz etc?
(or the setting you applied in bios, for example bios = 20 x 21 = 4.2ghz which is 4200mhz, hwinfo at full load should show 4199/4200mhz)

Both of those things are now disabled

I have accurate Idle temps of 8*C

Yes they all stay at 4300Mhz
===========================UPDATE=======================
Started 4.3Ghz no errors so f.....

Just as I was typing that I got ILLEGAL OUTSUM on CPU core #4, why does this happen?
and
Is the Corsair H55 silence edition cooler any good?
~~~UPDATE 2~~~
Started again upped voltage to 1.460V

Current Temps

CPU 40*C
CPU Low 30*C

Just got errors:

FATAL ERROR: Final result was 00000000, expected: E91EEB5A.

on cores #3 and #4

I would start another thread asking about coolers etc. (my feelings would be that the money spent on that cooler would be wasted on an fx4100, with an inadequate phase control motherboard)

the reason you had a single worker drop out is because of a lack of voltage.

now the fun part, you should really pause at 4.2 ghz and prime test for an hour+, and then read and read about overclocking.

I asked earlier about your voltages.
1. in bios
2.in desktop (zero load)
3. full load. (100%)

your desktop voltage (zero load) should now be different after disabling that feature. what is it?

theres a thing called LoadLine Calibration (LLC) which adjusts the difference between zero load and full load voltage drops.

you will have to read about this and learn as much as you can, this will give you the knowledge and power to get a stable overclock @ 4.3ghz and beyond.

heres a starting guide. http://www.masterslair.com/vdroop-and-load-line-calibration-is-vdroop-really-bad

your overclock @ 4.2ghz with 1.44 voltage is still over half a gig (600mhz) free performance. and for 24/7 use is good! amd recommend to stay below 1.5volts and so do most people.

I got to go sleep and well done on having the patience to test adequately between clocks. wink.gif remember to keep an eye on temperatures, frequencies and voltages when testing.......

I as well must sleep, I am testing Prime95 4.2Ghz @ 1.4400V to problems yet

Thanks for the help

I'll add you on steam smile.gif

What is the Steam ID? day19894 seems outdated

~~~~ERROR ILLEGAL OUTSUM ON #3~~~~~~~~

yes my steam is day19894. seems that your cpu/mobo requires more power to have a stable overclock.

have you read up on overclocking? and how long was it before the worker dropped out?

id suggest learning as much as you can because no one can test and retest voltage and frequencies apart from you.

then once you've mastered the basics of multiplier, voltage increments. youll need to learn about changing bus speeds, LLC (loadline calibration) and vdroop and vdrop etc

tbh I wouldn't be pushing any higher voltages without better cooling. you see to the left of the cpu are the vrms. they have a bunch of capicitors and square boxes, that's what controls the flow of voltage to the cpu. me and you have a 4+1 phase design which means its not suitable for overclocking, if you feel them whilst at load the get very hot which isn't good. most boards suitable to overclocking have a 8+1/12+1 phase design and have the vrm's heatsinked for better voltage control. read about it.
im actually buying a new motherboard so I can overclock higher. and you can get a good aftermarket air cooler which is easier and cheaper to maintain, which perform pretty well.

I dont think I can go any higher that 4.2, I still have to test 1.4800V before I can know for sure

At 1am (2 hours in to the test) core #4 got Fatal error, It was at 4200mhz @ 1.4600V
