OcUK backroom project "Cobra"

Looking sweet, making me want to take the MoBo out of mine to spray it now :D

Out of interest, what settings did you use for the overclock @ 4.8 and 5?

Is that the last 8 months of progress in sequential posts?! Looking good though - like the blue. Would also be interested in settings for 5GHz overclock. Currently running a 6700K with all 4 cores allowed to turbo up to 4.4GHz but it does get noticeably toaster.
 
to be honest its a damn good cpu , I got this at 5ghz with 1.32 volts on the cpu with slight tweaks to the SA voltage and dram voltage but I cant wait to get it into my loop as it was running the 5ghz on the asetek cooler with a max of 67degrees so I'm hoping to push it a little further, also managed to push the cache to 4.4 too;)
 
I've been trying to do this on and off for a while now but every time I make progress work goes mental so I have to sideline it for a bit.

What voltage are you running to get the 4.4 Cenedd? I notice that your on a gigabyte board??
 
Gigabyte Z170X Gaming 7, yes. Stock voltage, the only thing I've changed is the turbo frequency. In theory it should then clock down when idle or as cores are not in demand - although in practice it seems to be mostly (but not entirely) one up, all up.
That's why I was curious about how much voltage had to be pushed to get higher. I haven't pushed higher as temps started getting into the late 70s while gaming. That said, I suspect that more voltage is only going to make it hotter rather than find some mystical higher speed but lower temp :D
I'm working on more overkill cooling as you can see but I do wonder whether the EK monoblock is perhaps less efficient than a dedicated Evo. Not that I regret the choice - given only a single low speed fan in and one out on that case, the VRMs could probably use the chilling! I know the Samsung 950 Pro's did (at least in my head anyway) :D
 
In my experience with gigabyte boards and skylake they do seem to run the stock volatge quite high, you may find that you could probably get the same speed as the turbo but with less volts if you clocked it manually, what ram are you using and are you on the latest bios for the motherboard?
 
Interesting, thanks. I'll have to check the voltage when it clocks up. Can you still have it SpeedStep if clocked manually?

RAM is Team Xtreme 3733. Bios is F6f (slightly earlier beta than F6) as both the older and the more recent ones seem to be less stable. It has a habit of chucking all the settings out if it detects a boot failure. Trouble is this then loses all the settings for UEFI boot, Secure Boot and most importantly RST being in RAID mode...so RAID 0'd M.2's suddenly vanish and RAM clocks down to non-XMP. With it also appearing to flip flop back and forth with the secondary bios it is a real pain if you've just built one for a friend and it then fails to boot once they've driven it miles away!

Yes you can still have speedstep enabled but I didnt realise you were running 3733 ram, to be honest I would sacrifice a bit of that ram speed so that I could up the cpu a bit, I have noticed that with some gigabyte boards where they lose settings on a failed boot and was hoping they would sort it out with a bios update. I'm still pondering whether to use m.2 or not personally I might jus go for a 2tb ssd instead as I it seems the better option for me at the moment ;)
 
I started off with 3600ish RAM but I had to take the hit and swap for the faster RAM when it hit the rad in the build for a friend. The Team heatsink is really high. Speed is at XMP profile default and I've not played with the Bclk. I'll do some research once I've got the new setup running rather than continue to derail your log. Haven't really been overclocking in anger since Pentium Pro's and a bit on the PII and PIII :D

Personally I really like the M.2's as they're fast but perhaps more importantly they're really tidy. You can instantly lose the drive bays for space and you don't have SATA cables and power cables flapping about all over the place. I do have a stack of additional storage available over both SMB and iSCSI though.
The 950's do top 60C though. They apparently start throttling at 85C so it's technically not a problem but it makes me uncomfortable so I stuck heatsinks on them. Mine are one piece but needed machining to compensate for differences in height differences between chips. VGA chip heatsinks are almost as good and a lot easier. Lowers temps about 10-15 C at load and also the extra mass stops the temps from leaping at bursts of load.

Fair play, that's one hell of a chip you've got there! Any chance you could switch a couple of CPU's when 8 Pack isn't looking? Will post you mine in the morning :D

I was shocked just how easy this motherboard was to use, the ram was 3200mhz at C16 and for starters I went in at 4.8 with no issues so I upped it to 5GHZ!!! Into windows and ran Intel xtu for an hour to check stabiltiy........

I had the same board and CPU delivered yesterday, reading this has made my day :D
 
I had the Asus P8P67 Pro before. Finicky, irritating and WoL didn't work...which is why I avoided them like the plague this time around. Good rule of thumb therefore is to check which board I've bought and buy a different one :D
