I'm trying to overclock my FX-6300 but I haven't able to get past 4.1Ghz before my computer freezes or produces a BSOD. I'm running an air cooled system in an Antec Eleven Hundred with 9 120mm fans, a 200mm exhaust fan, and a NOCTUA NH-U12P SE2 CPU cooler. All I've done so far is changed the multiplier in the Bios and turned off CPU Performance Boost. Has anyone been able to achieve 4.5-5.0Ghz and if so, what voltage are you using and what are you using to cool your system?

Here's my setup:
AMD FX-6300
Gigabyte GA-990FXA-UD5
2 HD 7850's in crossfire
Kingston HyperX BLU Red Series 16gb (2x8gb) cas latency 7 with 7-7-7-20 timing @ 1333Mhz (CPU-Z is showing 1342Mhz)

Hi.

What voltage and temps do you have in this moment?

Assuming your temps are normal, you'll achieve the best overclocking results by bumping the bus frequency as well as the multiplier. You'll have to fiddle with both (along with the voltage) to find the points in each that give you the highest stable overclock, every piece of silicon is different.

Make sure to de-couple the frequency for the memory from the CPU's.

Good luck!

P.S., OC'd xfire'd 7850's are hot like supermodel ninjas, amirite? :)

Right now I'm stuck @ 4.1Ghz at 1.425V. Running idle my temp is 26C and under load it jumps to 54C. While doing my research last night, I've read that other people had to turn off cool and quiet and leave llc set to auto.

quilciri your right about the oc'd xfired 7850's. Best decision I made in regards to my first build.

hey,

I am currently running prime95(1 hour in), on the the same cpu and MB as you.

I am at 4.5 ghz 1.360v 54c 1 hour in. I did disable 1 module(2 cores,) as when i got to 4.5ghz with 6 cores, the voltage it took to run got my temps higher then i like(60c.)

i had all six cores going at about 4.4ghz pretty good. i tried for 4.8ghz, got it stable, but jumped up to 64c. so i am shooting for 4.5ghz.

also on this board disable the application manager something er rather. it was causing the frequency to jump around.

Edit: forgot to note Im using a CM 212 evo, idle at 22c

I tried shooting for 4.5Ghz and failed miserably. I had to pull the battery out of the board to reset the Bios back to stock. I'm back running at 4.1Ghz. As this is my first go around at overclocking a cpu, I'm definitely frustrated.

you have a gigabyte board. it has dual bios, shouldnt have to pull battery or reset cmos.

yeah i just did 2 hours prime95, 4.5ghz 1.360 v 56c(highest.) then i ran the heaven dx11 bench and the whole thing started acting wierd! kept giving me a nvidia driver error, but said it had corrected itself. re installed all the drivers and it persists. me thinks the oc is not as stable as i was thinking. going back to 6 cores and 4.2ghz!

...maybe the cpu! exchange it if you can. i just did mine today thinking it was busted...

oh yeah and update your MB bios. f11 being the newest!

Unfortunately the monitor wasn't receiving the signal anymore, so I just went ahead and pulled the battery. It was a quick simple fix. Thanks for the heads up about the MB Bios update. I'm going to try one more attempt @ 4.3Ghz before the night is done.

yeah just tried the 6 cores at 4.5ghz again. no luck! the had to go to +0.125% voltage bump, which took me to 1.42v, which promptly shot the temps to 64c. so I may try the rice sized dot of tim over the pea sized...see if that changes anything. may need a new cooler :( 

good luck! keep me posted.
January 3, 2013 2:06:58 PM

Well I just tried 4.5ghz, but my system kept restarting itself. 4.4ghz ran for a 10 min before I got a BSOD. At 4.3gz I was able to run prime95 for 30 min before receiving a BSOD. Backed her down to 4.2ghz @ 1.36V so far I failed two stress tests. My rig is back at 4.1ghz. I need to stop for a little bit, get my head right, and do some more research.

Yeah breaks are a good idea!

I think im staying at 4.2ghz. any higher and i get to much heat. I may need a new cooler...i wonder if it would help any!?

oh was just thinking! have you tried disabling the crossfire with you oc?
January 3, 2013 3:10:12 PM

I haven't tried disabling the crossfire yet. I'll disable it and see what happens.

It appears I finally found a sweet spot. Currently I'm at 4.2ghz @ 1.36V. All I did was raise the multiplier and increase the timing of my ram to 10-10-10-30 @ 1866mhz.

are you ocing your ram? or is it 1866? may need a bump in voltage for that! glad to hears is working out!
January 4, 2013 12:01:47 AM

Actually I'm doing a slight overclock of my ram. It's originally rated for 1600mhz but I've been playing around with the timings. It seems to run the same at 1866mhz as it did @ 1342mhz. I'm still trying to reach 4.5-5ghz but that will be for another day.

set your ram back to default. then try 4.5ghz

when i said bump in voltage i meant for the dram, and the NB.
January 4, 2013 1:18:35 AM

Great idea. I set the ram back to 1600mhz with a timing of 10-10-10-30 and bumped the core voltage up to 1.475v. Running prime95 right now for the last 20 min with temps ranging from 50C to 56C. CPU-Z is showing voltage holding steady @ 1.488V. I might have found the 4.5ghz sweet spot.

can prolly put your timings back to 9-9-9-24? if you oc the ram you need to bump up the voltage to the dram and NB. i hear a lot, that the ram oc isnt that noticeable. prolly better off using the power for the cpu\gpu.

Best solution

Put the ram at stock speeds... overclock only one thing
I run my fx 6300 4.2ghz with 1.356v

Voltages that normaly fx6300 uses:

4.2: 1.33-35
4.4: 1.37-38
4.5:1.40-42
4.6:1.42-45
4.8:1.47+

Even though I set the vcore voltage to 1.475v in the BIOS, CPU-Z is the showing the core voltage @ 1.44v. I tightened the the timing on the Ram to 9-9-9-24. Ran memtest for 2 hours with no errors, then ran prime95 for 8 hours with zero errors as well. My rig ran Assassin's Creed III for three hours and never got hotter than 40C. I'm very pleased with my results so far.

Good to hear!

got mine going, only ran prime 95 for an hour. i will do i longer test later. I did just play batman arkham city for like 4 hours. max settings, pretty much 60 fps!
cpu was a great up grade!
January 5, 2013 1:17:07 PM

Yep I'm glad I went with the FX-6300 instead of the 955 black edition. Since getting her to run @ 4.5ghz I need to run fraps to see what my frame rate is now. Before the overclock I was getting 45-50 with Assassin's Creed III and 55-60 with Battlefield 3.

yeah i was tesing with heaven d11 bench. im up to 48fps, from like 33fps.

had the 970be at 4.2ghz, and a 6870. but the fx6300 and gtx670, well worth the cash!!

enjoy your rig :)

hm...i must be doing something wrong...maybe you guys can help..ive gotten successful 4.635 OC with the 6300 (overnight run on p95, 2 hour occt, 20 pass HIGH STRESS IntelBurnTest) but anything less than 1.48v and it wont get past the 2nd or 3rd test after passing 512k test on prime95 (about the 11th to 18th test in...so like 15 to 20 min) could this be my memory? im running gskill 8 gb but its 2gb x 4 of the ripjaws 1600mhz 99924. and when i try just increasing the multiplier to 23x200 and running ram at 1333 (it only shows 1600 as the XMP profile but shows in cpu-z that i have 10700 ram) and ive also tried loosening my timings up to 9-10-9-25-27 and 10-10-10-25-27...no luck. my other settings are:
NB: 2200
HTLINK: Tried at 2200 2000 and auto
voltage: tried everything from 1.43 to 1.48
mobo: m5a97 r2.0
gpu: xfx 6870 1gb
case: cm storm enforcer
cooler: 212 evo 2x corsair sp120 hp editions push, pull. any help? :)  thx
also: my max temps occured in overnight prime95 testing of 60c but average temp was 58c ... thanks!

I have no idea. I'm just got my FX-6300 to run @4.6Ghz. I set the voltage in my bios to 1.475V, but CPU-Z shows the voltage is at 1.44V. I have my ram timings on my Kingstons set to 9-9-9-24-30 @1600, but CPU-Z is showing 1612Mhz. I didn't touch the NB and HTlink. During testing my max temps approached 63C but my average was 56C. I ordered stronger fans to increase the air flow coming into the case. I'm hoping the temps will go down after I switch out 4 weak intake fans.

vCore in the BIOS sets the upper limit of the voltage the motherboard will put through the CPU. This voltage will change as the workload changes, much the same way that the multiplier changes.

The FX-6300 'Vishera' should overclock the same as the FX-4300, but possibly not quite as far as the extra cores use more power and generate more heat. Forum and review reading indicates that the FX-8300 and FX-6300 can clock up to 4.6Ghz/4.7Ghz but the FX-4300 should hit about 5Ghz (though I haven't seen any voltage/multiplier/screenshots posted for that yet).

I have an FX-4300 clocked up to 4.5Ghz on +0.075v over stock voltage. I turned off dynamic performance boost but left Cool&Quiet enabled - I don't want my chip running at 4.5Ghz while I'm in Excel, but I want it to step up for gaming. I know this thread is mostly about the FX-4600 but with the same architecture, the same rules apply.
