1.41/ 1.425, any more and the socket hits 70°C which is my limit.

Kraken X40 is not up to the task unfortunately, even with a case full of fans in my NZXT H630 case. :(

Single thickness single rads can't deal with FX CPUs. I used to have a H60 and it could barely hold 4ghz. Anything more and it would throttle the CPU.

You need a H70 or above. H80, H100 etc.

sorry read that wrong ignore my post about air dunno why i thought kraken was air cooler lol

but as alex said not enough beef in that cooler

Yeah I purchased the X40 with a smaller case as I was on a budget, part way through the build I realised the X40 wouldn't fit. So as I'd had it out the box and in pieces, I thought better against sending it back so picked up a new case instead, I'd of thought the air flow with 4 x 200MM, 4 x 120MM and 2 140MM would be enough, I was wrong.:p

orch post your games in group on steam when u get chance m8 please :)

and anyone else then we can vote on what to play and when

will try and remember when I get home mate, there's not many to be honest and for the next few months I'm gunna be investing my limited gaming time pretty heavily in BF4 :cool:

The NB/mosfet water block arrived today. It's reassuringly heavy as it should be for the price.

I have cleared out the basement level in my case to fit a 240mm x 54mm thick rad which will be devoted solely to the FX8350 and NB/mosfet wattage.

I am still waiting a few parts which I ordered with the block but I will be in a position to start the rebuild at the weekend.
 
If I had the spare cash I would!

If I was to buy right now it would only scrape a 7950. I am put off by them as apparently pairing two up would 'bottleneck' me :rolleyes:

There seems to be lots of us with overclocks and people monitoring their temperatures. Can we include some pics or text with the:

  • clock speed
  • voltages
  • Temperature (CPU and Package)
  • Activity (i.e. benching; gaming; streaming etc)
  • Cooling solution
  • Duration

This would yield better data so others can determine if their cooling is performing, if their voltages were maybe too high/low etc.

When you monitor your CPU temps do you watch the 'Package' temp at all?
Click to expand...

Package is the one to watch m8. Package is the core temps dont want them over 62 according to amd myself on air had them near 70 this is when throttling starts. Personally I dont like the over 60 but on water max I have hit is 47 on prime gaming they dont touch much over 30

Some results:

  • clock speed: a mere 4.5ghz
  • voltages: 1.404 vcore bios (raises to 1.416 under load) / 1.206 cpu/nb
  • temps: 60C package / 65 socket
  • activity: p95 small FFTs
  • cooling: air (nh-u14s, single cpu fan, good quality case fans, all set to 100% for test)
  • duration: 10mins

Temps around 47C in aida64 for equivalent run, and there seems to be plenty of room to clock much higher on current cooling while maintaining temps in aida. However, certain games (eg ns2) heat up the cpu more than aida (I presume due to heat from the gpu), so I holding back on a higher overclock for now.

To stop the vcore jumping around up the vdda voltage m8 will stabilize vcore voltage

Also thats a great overclock for air dont be surprised if you cant run prime @ higher clocks as you temps are near limits just run aida64 bf3 if there good overclock shouldd be ok. Also try adding a second fan to push pull on cpu cooler helped my temps when I ran air

Farmerboy mate would you mind changing my details on the first page.

The system is:

8320 @ 4.8 GHz 24/7 at 1.44Vcore. Able to achieve 5.15 GHz stable at 1.53V
Cooling: Custom water with D5 pump/res, Phobya Xtreme 200mm rad and EK waterblock
Temps: max 59C package using LinX 20 cycles
Board is now Crosshair V Formula Z and this doesn't throttle the CPU.

Thanks :)
