Lol. I did of course mean 1.3125. Thanks for pointing out - will update my sig!

Heh

In answer to your question about cooling, if you're reaching 80c+ then that seems very high.
With my Triton the highest temp I've seen running Cinebench is around 65c even in the height of summer.

I think you do need to get a better cooler. What are you running now?
 
Hiya. I'm running a Titan Fenrir, with a single 14cm fan. With this setup (4GHz, no hyperthreading, no turbo), I'm hitting mid to high 70s after 30 minutes of prime95. If I could take 5-10 degrees off that, I'd be happy I reckon.

So I've taken the plunge. After much research, and based on the limitations of my Fractal R4 Define case as much as anything, I've ordered a Kraken X41. Should be a straightforward install, and the tubes should reach from the front of the case to the CPU socket. The X41 seems to perform quite well, and there's an option to add an extra 14cm fan to it as well.

Will report back once I have it installed.

Kelt - a question or 2 if I may.

I notice you have 4.4GHz and the same mobo as me. Are you able to set the mutliplier to 22 then? I thought that this was the turbo multiplier, and that it doesn't 'stick' if you set it in the BIOS.

Also, what Vcore do you need for that? Just so that I can compare my temps when I get the X41 installed.

Yes, mine is set at x22, turbos to 4.6Ghz across multiple cores.

Voltage is set at 1.35625V in bios, which after vdroop goes from 1.328 up to 1.344v in Windows depending upon load.
 
Mine does 4 GHz @ 1.300 V with HyperThreading. I know it won't work with 1.275 V but never bothered to check values in between. I can use the 22x multiplier but it always throttles so in effect it would be between 4 and 4.4 GHz. I haven't tried to get that stable though so I don't know how tricky that'd be. Otherwise to get over 4 GHz I'd need to use BCLK above 200 MHz, which my motherboard doesn't like.

I'm sure I could play with it more but I basically haven't had a need to. Maybe when I'm bored one day.

Just to be clear about the temps people are reporting/suggesting, I'm assuming these are cpu temps as reported by coretemp etc, and not cpu fan temps ?
 
Hi folks. So I got my Kraken X41 installed. I'm pretty impressed with the load temps, which are now about 60C after an hour of prime95 (versus mid to high 70s with my old air cooler). I have a further 14cm fan on order to create a push-pull, which will hopefully lower load temps further.

However, idle temps seem a little high, at around 36C - slightly higher than my air cooler. I'm thinking it might be an airflow problem, as I now have 2 x 14cm intake fans, and just a single 12cm exhaust fan. I'd prefer to keep positive pressure in the case, but I could I'll try adding another 14cm fan on the top of the case and maintain a positive pressure state.

Just rambling now!

Hiya. There isn't a Speedstep setting in the bios, but C1E and EIST are enabled. In fact, if memory serves (away from home just now), the only things that aren't enabled are hyperthreading and Turbo.

Another observation. My Fury X is now also idling at 36C, which makes me think that it's internal case temps that are to blame. I'll add a fan tomorrow and see if it helps.

4GHz stable HT on 1.328 Vcore. Tried 4.4 required way too much of a VCore boost, even 4.2 was running toasty on a H50 (that being said the H50 is about 4/5 years old now) so I settled for a solid 4GHz and get about 66c max temp in a real world scenario. Quite happy with it for the price.

Yeah they run cool, especially compared to Bloomfield. That seems like a fairly high voltage though, mine does 4 GHz on 1.30 V and I never bothered trying below that.

That does seem a high voltage for 4Ghz. I'm on the same board as yourself and 1.328v gets me 4.4Ghz rock solid.

Every chip is different though, I guess.
 
Whats the rest of your settings for it like QPI PLL etc? I couldn't get it to even boot with 4.4 at 1.330v set in the BIOS. Also hows the SP120's working for you, was looking at getting a set.

maybe it's a noob question but setting 1.300v in the BIOS gives 1.264v maxed in HWiNFO/HWMonitor etc, any reason why or is it just the CPU only using what it needs?
