My OC Bundle won't Overclock like it should

Hi All,

I recently got this bundle from OC:
http://www.overclockers.co.uk/showproduct.php?prodid=BU-116-OE&groupid=43&catid=2512
  • AMD FX-6 6300 3.5GHz @ 4.4GHz
  • Asus Sabertooth 990FX
  • 16Gb RAM 1600MHz

I've been using it absolute fine for about 2 weeks, and have stupidly only just checked/noticed that it was running at stock 3.5GHz speeds, not the Overclocked 4.4GHz.

A quick search on the forum tells me that the sometimes the motherboard will reset itself and there's a profile to set it back to, I do that - everything's fine and it's set to max 4.4gHz (in the BIOS).

I restart my PC and fire up Crysis3, I get less than 5 minutes in before my pc shuts down. I reboot to BIOS and my CPU temp is 60-65 degrees C (max for the CPU is ~62 I believe. edit: actually it was crashing out at 80-90, it just cools down quickly).

The 'bundle' came with the CPU on the motherboard and I had to re-apply my thermal paste, and refit the fan myself. I managed to put on the stock thermal paste (not the supplied Arctic Silver) and didn't quite know how much to put on (I put on the thinnest of transparent and even layers).

Should I take the heatsink off, clean up the CPU with rubbing alcohol and try again with the Arctic Silver? Surely that's not solely responsible for the massive temperature difference between stock and what should be run-in overclocked speeds though?!

Please shed some light on this for me - complete overclocking noob!

Thanks,
Chris

Hi guys,

ScottiB - It (was) definitely running at stock 3.5GHz.

deFiniLoGy - is there any guidelines to follow when applying it? e.g. "dollop the size of a pine nut, thinly and evenly spread out with a credit card (or similar)" - something like that?
 
Applying thermal paste:

A very small blob in the centre and thats it. Dont smooth it out, let the pressure from the heatsink spread the thermal paste out naturally as you'll get a more even coat that way.

Applying less is more.

The arctic stuff should be better as well, you should see some temp drops. I would check the bios voltage set and make sure its within spec.
 
AMD chips have no idea what temperature they are. Did you experience heavy system stuttering before shut down? That's what happens when your cpu overheats.

If it was a straight bluescreen/power off then it's probably something else.
 
I thought the throttle temp was 85 not 65? and the Bulldozers tend to get much hotter under OC than Intel. Also, you should only get shut down if throttling fails to control the temp, which tbh, shouldn't ever happen unless the cooler is poorly fitted or you have a fault.
 
It's turning off pretty consistently at ~62 degrees, with zero stuttering before hand.

The fans are ramping up at around 55 degrees (what I've set them too) but they don't cool it quick enough, and it goes past 62 degrees.

I'll reapply the thermal paste and see if that helps and report back !

Thanks for your help!
 
I've been playing a bit more and using AIDA64 and Prime95.

If I stress test in AIDA64 it will usually work fine, getting to 60-65 degrees (more than I thought) and working fine. As soon as I put Prime95 on it skyrockets to 80-90 degresss then turns off.

I think I thought this was happening at 62 because the temperature rises and falls so quickly (surely falling fast means the heatsink's working well?).

If I take the FSB from 220MHz to 200MHz it seems that prime95 runs happily around 65 degress and allows me to start overclocking.

Should I leave my FSB at 200MHz (stock I think) and bump my multiplier up until I'm getting 4.4GHz ? Will that affect performance?

Thanks in advance.
 
Think i've sorted it!

Hi all,

Think I've got to the bottom of it - I must have done a **** job of putting the stock thermal compound down, just swapped it out for arctic silver (after a quick rub down with cleaning alcolhol) and my temperatures are AMAZING in comparison!

This is AIDA64 Extreme's 'System Stability Test' :

the first dotted line is the in-built CPU stress test - which topped out at about 43 degrees. The second line is when I turned that off, as you can see it quite quickly dropped back to 35 degrees.
The circled 1 is where I turned on Prime95, as you can see that was much more intense and topped out around 52 degrees.

Here's my CPU-Z stats, as you can see I'm now on 4.4GHz as I should be :)

One question though - my RAM memory clock appears as 735.8MHz - shouldn't this be 1600MHz?!?!

Thanks for any help with the new memory issue/question and before any says, I know this isn't burned in, but in comparison within 2 minutes of turning Prime95 on before, it'd hit 80-90 degrees and shut the PC down! So I'm guessing it's a lot better ;)

Cheers,
Chris
 
You will need to double what the figure shows, as your running double data rate.

CPU-Z memory tab will also show the same figure.
 
Anything I need to know before hand? I.e. don't go too high otherwise the ram will break or something?

Either way, thanks very much for the help :)

EDIT: I've heard I should have a 1:1 ratio of FSB: DRAM - currently it's 3:10 according to CPU-Z.

Does that mean I should up my FSB and lower my CPU multiplier? (to keep 4.4GHz OC but up the ram to 1600MHz at a 1:1 ratio)
