2700k beyond 4.8ghz

murah · 27 Mar 2015 at 22:36

Now have my 2700k under water, doing 4.8ghz @ 1.376v might be able to notch that down slightly to 1.350v anyway I'd like to push the chip higher

Can you tell me the "max safe" voltage under water that you personally wouldn't go above without moving to LN2? I only use the PC for gaming and the odd video encode so won't be folding

Custom water or AIO, if its custom then benching at 1.5v, 24/7 etc 1.4-1.425v, check temps!!

custom water, currently hitting 60c prime/folding

Check with asus real bench for a more realistic load, ideally dont exceed 70c

At 1.4v and above it becomes difficult to cool but if your temps are good it's safe enough to go up to 1.425v as above

The 2700k I had did 1.368v 4.8GHz, 1.4v 4.9GHz and 5GHz needed around 1.45v.

I settled for 4.8GHz as the other two ran pretty hot, even under custom water.

1.4v and 80c to mid 80c

Personally I'd stay at 4.8ghz,but up to you

i go upto 1.62v on air on my 2600K for benching. i wouldn't run it much higher than 1.4v 24/7

temp while running asus real bench (benchmark mode) 4.8ghz @ 1.368v

Max temp 60c (package)

Core 1 - 54c
Core 2 - 60c
Core 3 - 58c
Core 4- 54c

CPU PLL voltage @ 1.750v

When you hit 80c in this bench, stop! This will give you 65-70c gaming temps etc which is perfectly fine.

Would you recommend the same temp on haswell Nick, on real bench at 4.7 on 1.300v mine will hit low 80's. That's the most strenuous program ill use. Lately been trying to hit 4.8, passes a few benchmarks at 1.31v but bsods on 101 in games. Which means more vcore, on a chip that hits 73c in games. I might wait until the oem warranty is up and scalp it.

Why fear 80c? 80-85c is perfectly fine in stress testing

1.45 is about tops 24/7 on this CPU. Dont do too much stress testing just run your own stuff. This is a true test of stability for what you use your pc for.

80-85 is fine.

Shall give it a go and report back , thanks
