AMD FX-4100 Zambezi - Overclocking [Help!]

post #1 of 43
Thread Starter 
First of all I don't want to make a noob mistake so here are ALL of my specs:

CPU: AMD FX-4100 Zambezi
CPU Cooler: Stock
Current Clock Multiplier: x20 (4.00GHz); Stock speed 3.6GHz
Core Voltage: 1.344 V
RAM: 8GBs (x2 4GB) Corsair XM3 DDR3-1333Mhz
RAM Voltage: 1.5-1.6
Motherboard: Gigabyte GA-78LMT-SP2
GPU: On-board (Soon to bee MSI 660 Ti power edition biggrin.gif)
BIOS Version: F3
Power Supply: Thermaltake 600W Non-Modular

=====================================================

I am VERY new to Overclocking just started yesterday so here we go:

I have OC'd my 4100 to 4.0Ghz as far as I know its completely stable. (Prime95 for 24 Hours and 31 Minutes with 32C as average temps) I've tried to go higher (4.1Ghz and 4.2Ghz) and I cant even run Prime95 for 15-30 minutes without getting ILLEGAL OUTCOME or FATAL ERROR (Bunch or 0's or random combinations) Expected (Random numbers and letters).

If anyone would kindly tell me how to get high speeds, I'm fine with changing voltages in my BIOS, but nothing extreme. I would like to know EXACTLY what to have in my BIOS or even some better custom Prime95 settings to get the best results out of the tests.

Thanks!

PS: I have looked at other forums and threads to no avail

Bump volts til its stable at whatever clocks you want or cooler limit.

you also need to up the voltage little by little as you up the multiplyer...

wehat do you have for cooling?

ive been overclocking mine today and getting some benches in.

the problem youre experiencing is probably lack of core voltage. my motherboard is cheap and nasty and ive even pushed 1.6v through, only for benches tho. are you hoping to keep the overclock 24/7?

if I was you id set my vcore to 1.45 and up the multiplier a notch and test for twenty mins on prime each time, when a worker drops out then go down a multi and test for longer.

also that 4gz is easy for the 4100, I start getting problems at 4.7+. also you don't really need to run prime that long until you find a clock you are happy with. what is your goal btw?

oh I can set my bios settings on auto and the multi to have 4.4ghz and its stable 24/7

and like the others asked what coolong have you got?

and prime95 is probably a good starting point for testing, just have the torture blend test and stick with it.

@Speced
I have done this to no avail

@Malo
Thanks, will try this now

Stock Cooler

@d1nky
I am hoping to keep it 24/7, but my MOBO only has like 1.45xx-1.50xx V as my Vcore voltages and my goal is 4.2+

I HAVE STOCK COOLING AND COOL MASTER 2000RPM BLUE LED FANS

be careful with overclocking on your motherboard with stock cooling


https://spreadsheets.google.com/spreadsheet/pub?key=0AgN1D79Joo7tdE9xMUFlMEVWeFhuckJEVF9aMmtpUFE&gid=3

(GA-78LMT-S2P (r3.1) 4+1 No 140W OC with cooling

you will run into problems probably above 4.4ghz.

if I were you quickly set multiplier/ frequencies to stock. 18x200. disable ce6/1 turbocore, power saving features etc.

set my vcore to 1.45 and see what temps you get with prime95, the temps should rise quickly and level off for about 5-10mins. remember to have the fan set to turbo or manual to max @ 70*c

if your temps go crazy I wouldn't oc till a new cooler etc

question: what is the tdp value for compatible cpus?
I cant find it, it should be something like am3 125 tdp or 95 tdp

I forgot the answers in the spreasheet....140watt tdp so this gives you a little overclock room because the 4100 is 95w

Alright, Ive been running prime95 at 4.1GHz for almost 30 Mins no problems, temp is about 40C at the MAX with voltage at 1.4400

Should I go up from here?, considering that I have 30~ degrees of wiggle room?
post #8 of 43
wiggle room hahaha!! if I was you on stock cooler aim to stay well below 60*c and youll be ok.

what programs have you got installed?

I recommend:

cpuz http://www.cpuid.com/softwares/cpu-z.html
hwinfo64 http://www.hwinfo.com/download64.html

best to keep it simple.

now up the multiplier one notch and test for twenty min, restart and repeat.

watch temps closely. now the cpu has that amount of power to the cores (1.4v) temps wont change too drastically. its the power input that increases temps a lot

also when you have hwinfo installed look for the cpu vcore in sensors. and make a note of the lowest and highest.

I use both of those

Then I have 20 Degrees, or whatever tickles your peach
post #10 of 43
whatever tickles your peach hahaha! its whatever noise you can stand when the cpu fan is @100%

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)?
