FX 6300 ... impossible OC?

post #1 of 14
Thread Starter 
Hi guys I hope you can help me with this, about a year ago I got my Fx 6300, mobo and some other parts, last month I managed to update my GPU from a rusty HD 5450 to a MSI GTX 750Ti, I know isn't a top tier card to play all of the new games in ultra quality but I'm happy with it, I play mainly MOBAs and a few FPS, the point is I'm trying to get some more juice to play Tom Clancy's The Division, so I tried a "basic" overclock and it worked
from the stock 3.5 GHz to 4 GHz, that gave me a few more frames in game so I tried to get a little bit more, been reading some guides here and in some other sites, watched a lot of youtube vids and managed to get it to 4.4 GHz, but there's a huge problem, my vcore is WAY too high, not even close to what others post

I need at least 1.48v to get stable at 4.4GHz and with a FSB boost, for some reason it's impossible for my cpu to use only multiplier, if I use a lower voltage, let's say 1.41v it just won't boot at all, black screen, at 1.42v it manages to boot windows but it hangs after 10 seconds or shows a BSOD
a friend of mine has it running at 4.8GHz so I tried that too, but I only manage to make it stable using 1.56v

there's another problem, my BIOS shows the vcore at 1.56v but windows programs like cpu-z or AIDA shows between 1.579v and 1.600v and I have no idea why ... it works but I really don't want to overvolt that much

my rig is
the "cursed" FX 6300
MSI 990FXA GD65v2
g.skill 2x4GB 1600MHz + SuperTalent Performance 4GB 1600MHz too
Thermaltake Smart 650w
Corsair H100i Cooling w/ 4 Corsair turbo SP fans
High RPM 8x8 fan straight to the northbridge (otherwise its temp is 175°F/ 80°c)
Corsair 760T w/ 5 fans if we don't count the watercooler ones
MSI GTX 750Ti


the fan I managed to attach

config right now is set to (BIOS setting)

FSB 240
CPU Multiplier: 20
CPU-NB Ratio: 10 (2400MHz)
HT Link Freq: 2400
HT Link I/O: 16 bit in both
Turbo Core: Disabled
OC Genie: Disabled
Cores: Manual, all of them enabled

CPU Voltage: 1.5630v
CPU-NB Voltage: 1.4650v
DRAM Voltage: 1.640v
NB Voltage: 1.394v <- lower = system hangs randomly


Aux is my northbridge temp, the fan is doing a great job there

while playing the CPU never goes over 48°C and the CPU Core #1 - #6 are between 40°C and 68°C depending of the game but it's never a constant value, it fluctuates a lot while playing
if I use furmark cpuburner the CPU goes up to 52°C & the Core goes up to 74°C

my main questions are

a) how I can get a stable OC without overvolting that much?

b) why voltage is that high if i'm in idle mode? (just using chrome and paint)

c) if i stress test it or play a game the voltage drops to 1.57 ~ 1.59 why?

d) should I trust the BIOS setting or the AIDA sensor?

Hey now..... my CHV-Z's can't keep up with my GD 80 wink.gif .

I've had 4 or 5 of those motherboards pass through my hands on the way to customers. The least I could get out of one running an 8 core prime stable was 4.7 ghz.

A healthy 990 FXA GD- 65 should normally push a six core to close to 5 ghz when properly set up.

At this point I'd say he might have managed to damage something due to hightemps/overvolting. Shouldn't need anywhere near that amount of NB or cpu/nb to be stable - damaged IMC perhaps?

Make sure you have good airflow over the VRM / socket area and start over with the overclock.

If you aren't on the latest bios, update it.

Download HWINFO - open it and run a relatively light bench , like wprime 1032 check the temps and voltages after clearing cmos of just after a bios update at stock values.
It's important to know these numbers before proceeding to overclock. I can't imagine a healthy 6300 needing that much juice at those clocks.

EDIT: I just realized you are mixing wildly different RAM kookoo.gif.... take the super talent's out and try it with just the g-skills

I have undone everything now, to start all over again, at 4.0GHz hwinfo reports 1.3375v in cpu and 1.2000v NB
ST ram is out, I'll try at least 4.4 GHz using 1.42v using only multiplier but i don't know if it'll work

I'm not sure what voltage i should use for "CPU/NB" doh.gif

Leave it ( cpu/nb v ) in auto for now, MSI boards do a good job of giving themselves what they need as long as it isn't confused by different ram kits.

I'm running a FX6300 myself @ 4.4ghz just to keep it cool, 4.5+ takes decent bit more voltage but its been humming away happily at 4.4 for like last 2 years with uptimes in the 3-4 month range.

I'm on a Gigabyte 990FX-UD3 motherboard through.

Here's the Bio's pages; https://www.dropbox.com/sh/0aoysef8ibjgfey/AAA3TOzEsMoc-vKPUVze7lpqa?dl=0

Basic rundown of it is, 4.4ghz OC with 4.2 from the Multiplier and +10mh/z (210) per multi from the BCLCK Don't ask me why I did that I have noooo idea.

Voltages are Vcore 1.332, north bridge 1.125, and all processor power saving features on. This use to peak at about 60C on my H60, now good bit of dust etc, peaks around 70c highest I've seen.

Oh the CHV-Z has too many bios options over the GD 80. OC made easy? buttkick.gif

IM KIDDING!!!

personally never had a "bad" MSI OC experience, just had one particular board that needed RMA 3 freeking times. The sad part was it wasn't even my board...... frown.gif

I'd concur with the advice about the RAM. Sometimes mixing RAM types causes problems; I've done it before and got away with it, but it doesn't always yield the best results.

Running the reference clock (what you're calling the FSB) at 240 is right on the limit of what most FX processors can deal with. Don't ask me why, but that's just how it goes. You can often get a better OC by playing around with the multiplier and the ref clock both, but the ref clock hits a wall in the 230-240 range. I had an 8350 for a long time, and it would run 4.85 GHz stable at 231*21, but couldn't run 4.8 stable at 200*24 even if I volted the hell out of it. No FX is the same as the other, so you'll have to use trial and error to see what the best combination is. But there's no way that any 6300 should need to have an effective vcore of 1.6 to reach 4.4 GHz.

I think in your situation, I would try 230*19 (4.37 GHz) at 1.5v with LLC on default settings and just one brand of RAM installed (make sure you RAM speed in spec with the ref clock boost), and see what happens. If it works, see if you can start lowering the vcore.

The GD-80 runs cooler and that's where it has an advantage when using limited cooling ( custom water). If I was using extreme cooling, I'm pretty sure the CHV-z's would express an advantage.
I've had 2 MSI motherboards I've submitted for RMA out of 100+ I've built with in the last 13 years. By comparison I've had 3 chv-z's ( only Asus boards I've owned) , 1 was an open box deal that was DOA , 1 has been RMA'd 2 times ( broken trace near the I/o panel then boot loop issues), and one has been flawless.

Got my CHVZ brand spanking new out of the box. Overclocked a good deal on this board including Phenom II and Opterons. Some extreme, some water looped and some on air.

The one thing I haven't done is ultra low watt chips on it yet. The GD 80 and CHVZ are great boards. The Sabortooth I had an issue with cold bugs ( was rev 1) but other wise OCed like a champ. I gave it to Scott and he tweaked the bios to overcome the cold boot and he's had nothing but a blast with it.

The Gigabyte UD7 I had was a good board but received it from a reviewer that had really mangled up the socket pretty bad. He wouldn't tell me how he done it, but it had tons of bells and whistles. I got One processor on it running. When I swapped to the 8100, it fried the chip and the board. I obviously didn't get the repair as well as I had thought..... Could not RMA this one.

I haven't tried AsRock with AMD yet though....
