Overclocking AMD Vishera FX-6300 to 4.3Ghz

[Paolo Figueras]

I just wanted to share what I've done with my 6300.

Sys Specs:
CPU: FX-6300
Cooler: Cooler Master 212 Evo
MoBo: Sabertooth R2 990fx
GPU: Radeon HD 7950 Boost State
Ram: G.Skill Sniper 8GB 1866 9-10-9-28
PSU: Rosewill 1000w

First thing I did was, I disable all power saving option in the bios and after that I put the Multiplier to x 21.5 with 200Mhz bus speed. I didn't raised the voltage for the CPU because it still runs stable. I stressed test my CPU with prime 95 for 3hr without any error. After that I changed the NB to 2400Mhz and HT Link Speed to 2200Mhz. I put the NB voltage to 1.35 and it was stable with that Voltage.

I tested the system with prime95 blend for 24hr with no error. The max temp I get is 56c which is a good temperature for my CPU. I also overclocked my 7950 from 925Mhz to 1100Mhz and the memory to 1250Mhz to 1500Mhz. When in stock speed both GPU and CPU, I get AVG 63.0FPS using cinebench. OC GPU stock CPU I get 67.FPS. OC both I get 75.0FPS which isn't much of a great raise. My system runs crysis 3 with avg of 58Fps all max. I was able to get the avg FPS using fraps

Now enable all the power saving features

My FX 6300 is perfectly stable at 4.7 GHz with everything turned on . I do have a better cooler than you though

Not bad, but your mobo should be good enough to push the FX-6300 further, you should be able to reach 4.5Ghz at least. Just keep an eye on the NB temps. I just got one of these, very good CPU for the price.

Yea that's the problem, my cooler is ehhh. I actually pushed this to 4.8 and It was stable. BUT temp is way too hot for the CPU. It goes around 75.

Yea I will start pushing this further when I get a liquid cooler. It's way too hot above 4.5. I pushed it about 4.8 It's just too hot. 78 is max.

My take on fx6300 in 30 days of use.
M5a97evo2.0, 16gVengence1600, VX550 psu, Saph7750, 400R case
Initially I used OE cpu cooler it was good to 4MHz overclocking w/ temps reaching 65C (as indicated by ASUS Bios). Delta T is most important, difference between indicated CPU and MB (motherboard) temps ~ temp inside the computer case. With OE cooler @ 4Mhz this deltaT was 65-30=35 degC in stable prime95. Incidentally, typical benchmarks were: Cinebench-CPU-4.48 (3,5Mhz) 4.92(4Mhz), GL-66-68fps; CPU pass mark- 6800@3,5Mhz and 7400@4Mhz).
Just the other day I added the 212EVO cooler and it made a huge difference. I elected not to use liquid cooling since I hate maintenance and need a robust system which will run for 4-5 years. Water and electronics don't mix. At 4840Mhz (22.0/220/1,41875Vcpu) running video conversion was reaching CPU temp of 68C and MB temp of 28C, ie. deltaT of 40 degC, while at the same time total power wattage w/o monitor was 340W (idle OE setting of 105W, OC idle at 125W). I have not run torture test for stability verification, however in functional utilities the stability was there. Benchmark wise, Cineb-6,10, GL-73fps, CPU passmark-9050.
I recommend to pay particular attention to how the cooler fan is integrated with the 212 cooler. I made sure that vertical position of the fan is such that the lower external edge of fan housing is level with the lowest fin. This ensures highest air flow velocity around the fins closest to CPU, ie. hottest fins. I then noticed large gaps (fins-fan housing) which would bleed off the air flow to the detriment of cooling efficiency and elected to place narrow strips of duct tape effectively sealing the gap between cooling fan and cooler fins top and bottom. I don't have any comparison data before/aft since this was the first thing I did right from the start. Also note, that sucking air is most effective way of cooling (thermodynamics), allowing the benefit of plenty space around RAM and dumping hot air near the exhaust fan.

78 on a torture test is not too hot, its perfectly safe. i have my ib 3570k at 4.6 and in prime it hits 78-79 with an evo 212. during hours of intense gaming, planetside 2 (which is very cpu dependent) it maxes at 68. start worrying when in real world experiences like gaming it gets past 80.

I'm at 4.7ghz at the moment rock solid stable.

I agree 4.3ghz is very tame, I also have cool and quiet enabled so its not running flatout all the time.

I have this cooler: http://www.tigerdirect.com/applications/searchtools/item-details.asp?EdpNo=6085172&SRCCODE=WEBGOOPA&cm_mmc_o=mH4CjC7BBTkwCjCV1-CjCE&gclid=CLvNkLSk5bkCFatj7AodAT4AeA

which doesnt let it go any higher than about 50 Celsius and with cool and quiets help my idle temps are about 20 degrees.

why is you HT 2200mhz stock should be 2600. some reson mine runs stock at 2400 tho not 2600 whats up with that. so I bumped it to 2600 myself. your NB should 2000 MHz not 2400. also I had to bump up voltages myself just to get it to run stable at 4.1. which I now have. g skill ripjaw x 8gb 1866 CL8 9 9 24 stock at 1600 had to OC 1866 manually and bumped up CPU-NB voltage to stableize the memory controller in the cpu. I am using a msi 970a-g46 mobo. amd fx 6300 at 4.1 ghz vcore voltage is 1.39 to 1.40 cpu voltage is 1.36 cpu-nb voltage is 1.31 my NB and SB voltages are both 1.09. those are auto clocked should I adjust those myself?

you cant have the cool n quiet enables in overclock mode dude

 

[ffejster25]

Now enable all the power saving features

My FX 6300 is perfectly stable at 4.7 GHz with everything turned on . I do have a better cooler than you though

you cant have the power saving options on when overclocked can have a sudden jump in frequency and fry your crap have to turn it off dude

 

[razzell77]

i have my 6300 stable at 4.6ghz on 1.44 volts.running prime i get max temps of 55 with an ambient temp of around 30 degrees so its a warm room but i do run a custom water cooling loop for the cpu.this is the first overclock and now my tim is burned in i will push it a bit further.

sys specs
cpu: 6300
mobo m5a99fx pro r2.0
supremecy elite water block
arctic alumina which required 60 hours burn in to see temps drop by 3-4 degrees.
g-skill 1600 8g
corsair 1200w

Ahhhhhh dude you would not be correct about that .

Overclocking might fry your crap , but enabling cool'n'quiet wont be the cause of anything except power saving .
Some chips might clock higher if you disable it . Maybe most chips . But the difference will be small and not worth it when you balance that against the power savings , and lowering the chips temperature at idle
