deafandy Posted September 2, 2015 Share Posted September 2, 2015 1st post, hello haven't figured my way round this place yet, so i thought I'd just blurt out my question and hope someone could point me in the right direction... what's the current CPU record for overclocking a 4790K without going below zero celsius? thanks in advance andy / tech-wreck Quote Link to comment Share on other sites More sharing options...
xxbassplayerxx Posted September 2, 2015 Share Posted September 2, 2015 When you look up a processor, you can also toggle different types of cooling. While water cooling doesn't guarantee above-ambient cooling, it's very likely. Looks like the record is 5600MHz: http://hwbot.org/benchmark/cpu_frequency/rankings?hardwareTypeId=processor_3621&cores=4#start=0#interval=20#coolingType=3 http://hwbot.org/submission/2937238_don_matto_cpu_frequency_core_i7_4790k_5600_mhz Quote Link to comment Share on other sites More sharing options...

xxbassplayerxx Posted September 3, 2015 Share Posted September 3, 2015 thankyou i intend to smash 6GHz, btw; cue laughter 6GHz on water? I'll be quite surprised! Most chips need pretty cold temperatures to do 6GHz. Quote Link to comment Share on other sites More sharing options...
Guest TheMadDutchDude Posted September 3, 2015 Share Posted September 3, 2015 6G might be possible in Antarctica, but that's about it. Quote Link to comment Share on other sites More sharing options...

oc_ninja Posted September 3, 2015 Share Posted September 3, 2015 i enjoy being told that something can't be done. challenge accepted Correct me if I'm wrong, your plan is to push 4790K to as high as 6.0Ghz with ambient air/liquid cooling, isn't it? You claim you used to make a lot impossibles become possible. However, this time, I don't think you can win if you are challenging physics, aka the King of Science.

deafandy Posted September 3, 2015 Author Share Posted September 3, 2015 consider yourself corrected. i said 'above zero' and by that i mean 'just above the Dew point'. i have no beef with the king of science, but if 5.6GHz is the record for ambient limited watercooling, then i'm confident that 6 is possible with chilled water. or, all that liquid will come in handy for putting out the fire...

oc_ninja Posted September 3, 2015 Share Posted September 3, 2015 I'm confused, you want to do it with 'above Dew Point' cooling, or chilled water? Assuming 25degreeC room temp with 50%(+-3%) relative humidity, then Dew Point is 13.86 (+-0.9)degreeC, I believe chilled water is definitely below Dew Point. Besides, I'm certain current record of 5.6Ghz already invokes pumping icy water or blowing chilled air to keep CPU as cool as possible. Also, you didn't make yourself clear, you simply want 6.0Ghz validation for a few seconds, or you'd like to do some light bench @ 6.0Ghz?

deafandy Posted September 3, 2015 Author Share Posted September 3, 2015 ambient temperatures are nowhere near 25c (the house is well insulated and when the central heating is on it's never above 19), and i can control the humidity. coolant temperature will be around 4-5 Celsius, like the milk in your fridge, i'd say that was chilled. and the tables aren't that clear, or i missed the bit that says 'stable' or 'unstable'. either way i'm aiming for the stars... my target is still 6GHz, and failure is always an option. apart from failing to try, that does not compute.

oc_ninja Posted September 3, 2015 Share Posted September 3, 2015 In order to hit 6.0ghz, you will need a very good 4790K, not sure how golden your chip is. On the other hand, I think your chance is low with a random chip. Quote Link to comment Share on other sites More sharing options...

oc_ninja Posted September 3, 2015 Share Posted September 3, 2015 So you are saying you don't even have the CPU yet? Quote Link to comment Share on other sites More sharing options...
deafandy Posted September 3, 2015 Author Share Posted September 3, 2015 hey, it's a work in progress i still have lots to do so it'll probably be early 2016 when it's up and running. Quote Link to comment Share on other sites More sharing options...
