H110 enough for 4.5-4.7Ghz on 4770K

[dugdiamond]

Yeah it will if you know what youre doing in the bios.

Ive even had £100 mobo's doing it.... tut tut

I think it is best i shut up then!!! lol

The likelihood of running 2400MHz RAM clocks decreases as your CPU clock speeds increase. Your specific processor may be capable of doing 4.8GHz, but only with a memory clock speed of 1600MHz, or luck of the draw might allow you to do 2400MHz with a 4.8GHz CPU clock. On the other hand, your Haswell may only be stable with a 4.5GHz processor clock and work just fine with 2400MHz memory.

I have 2x 8GB sticks of Corsair Vengeance DDR3 that are rated at 2400MHz (10-12-12-31) and I had found that hitting 2400MHz was not a chore... AT STOCK, but there is the caveat... it comes back to your specific processor.

I now use 16GB [4x4GB] of Vengeance at 1866MHz (9-10-9-27-2T), and I can push the full 16GB to 2000MHz at 4.8GHz.

Stable 24/7 under H110, with 4x Apache Black Super Silent 140mm Fans (push/pull) and 4pin CPU Speed Reducers fitted.

It purrs.

Its a BIOS thing dug. Ive got i3's here doing 2666 just with XMP

I recently got a 4770k and a z87 sabertooth with an h100i setup as push. I tried overclocking it up to 4.4Ghz and with an ambient temp of 32 degrees the temps were too high (90-100 degrees). So unless you got luckier with your chip I believe that you need something better than the h100. I'm seriously thinking of deliding this chip.

When I mounted my H110 I had the feeling that it wasn't pushed all the way down on the CPU (still have that feeling), as all the screws bottomed out on the nuts with very little force applied.

However, when I run 'BurninTest max CPU temp' with just 1 fan in push and at 4.4GHz (1.2V) I only get to 70C (25 ambient), so something is working. Perhaps your cooler is sitting with marginal connection.

Corsair mounting system doesn't always work depending on your motherboard.. I have had to use washers with a few of my old builds...

OK than we expect new Prime95 not so strong, because Haswell.
After few years seems some old stability test are not so good any more.

People will swallow everything what Intel give us. And later we will cry few days when no OC at all but humans are really weird. No more planing about nothing in future. First must saw application see 2 samples in real life and than shooping.
We dig own grave not calling things with real name.
I doubt we can change and with complain but I feel better when I say them what think about their 3-5 years of development.

Just an update. Finally getting around to overclocking.

I've got my 4770k stable at 4.5Ghz at 1.22 vcore and max temps with the H110 in pull only are hitting 85C. RAM is at 2400mhz XMP setting.

I'm having trouble pushing over 4.5Ghz though. The voltage needed to get Prime stable at 4.6-4.7Ghz is pushing temps up quite high. At 1.3 vcore and 4.6Ghz i was getting thermal throttling in prime after about 30 mins (normally i'd want to run prime atleast 12 hours to declare stability)

don't the haswell cpu's have crap tim inside them
i have a 3770k oc'd to 4.5ghz 1.3v in bios extreme llc
(not really a good chip) and with a h100i it was throttling till i de-lidded it and now it don't go beyond 70c with liquid pro but big risk tho you might destroy your cpu if done wrong

Yer Haswell has the same issue with the glue under the IHS as ivy.

I haven't pushed my overclock any more, but found my instability was due to cache voltage not vcore so I can probably push a bit higher before hitting the temp wall.

Probably not going to delid, atleast not for the moment.

Just been using it at 4.5Ghz for the time being and it's quicker than my 2600k at 4.9Ghz.

I think you will find its not worth the volts to get higher than 4.5ghz
I know my 3770k needs 1.35v for 4.6ghz its just not worth the extra 0.05v for 100mhz more but if you dont mind pushing your chip then go for it i dont really have the money to replace mine at the mo so im trying to keep it a safe oc for now
