So I bought a used 5820k on the bay..

[Bluntwrapped]

Thanks for the encouragement guys. I'm finally back home after a pretty hellish week at work. It'll be great to sit down this weekend and have the time to play with it properly. Looks like I'm going to be held back a bit by the air cooler I'm using but I'll post the results as soon as I can. I'm tempted to set up a temporary loop but I've only got a spare 120mm rad sitting so probably not worth the hassle.

The kicker is this isn't for me.. I'm building a new workstation for my dad. He's upgrading from a 2009 iMac so that'll be his comparison he doesn't quite know what to expect so I think he's in for a surprise lol.

Hey, can i be a 6800k friend?

Bluntwrapped, thats a great clock if you can get 4.6ghz stable. I've hit a wall at 4.2ghz but temps are brilliant. I can get 4.4ghz but ive got to push on to 1.4v and temps go through the roof. I'm running it on a cheapo coolermaster 120mm AIO as my h100i wont fit due to my ram hitting the rad. Max temps i've seen is 65c!

Welcome to the club mate Although, I don't know if I can be the one to say that because I'm here on behalf of my old man lol.

What voltage are you using for 4.2? Those temps aound great. Did you leave cache at stock?

enjoy playing with new cpu the nice thing about the 6800k is it takes quicker ram than the 5820

I'm at 1.27v with an offset of +15. Not touched cache but i have looked for it and cant find anything in the bios?

I'm not familiar with the bios of your board mate but I think it falls under target ring frequency.

This is worth a read if you haven't read it. If you jump to page 3 it covers uncore/ring overclocking - http://edgeup.asus.com/2016/06/17/broadwell-e-overclocking-guide/

This chip is looking great so far. I haven't tried but I'm assuming it'll do 4 and 4.1 with stock voltage. I've got 4.2 1.175v, 4.3 1.230v, 4.4 1.3v profiles saved in the bios now.

It's desperately wanting to be water cooled. 1.3v air cooling = insane temps. I reckon I could drop the voltage for 4.4 if i had it running cooler. 4.5 is definitely doable but there's no way for me to check without putting the temp way beyond comfort zone.

I've had a dead CPU sold to me as working and two "working" motherboards. Both with bent pins from the bay.

Wouldn't buy anything from there again unless it's 100% working with all required photos. I've had some bargains from there too so it's not all bad.

Anyway glad it worked out, enjoy your new CPU .

It's a shame as it is my only method of selling used items (no access to MM) and people are getting put off by a minority of dishonest people ruining it for the honest ones among us. Though when I sold my old motherboard, CPU, and RAM on there I did take a lot of photos and showed it working.

This ^

Question the sellers if they haven't provided much in the way of reassurance, and if you go to sell, put as much as you can on there to show everything in top tier condition.

I had one person try and return a motherboard because they bent the pins installing the wrong type of CPU. Luckily I had photos and video evidence of everything in my listings all working together and the bay immediately shut down his request for a return.

Sucks that you got shunted with a dodgy chip but at least all that's been lost is a little bit of time turn around getting a different one

Cheers for the link, i'll check it out.

The 6800k's usually top out at around 4.2ghz with it either becoming unstable or volts and temps go through the roof. You've got a good one there!

 

[Bluntwrapped]

The ASUS thermal control tool looks great I haven't set it up yet but it you can set a max stable OC in the bios then set a lower stable clock with less voltage though the OS.

When you reach the temperature threshold the multi and voltage drop to the lower OC and voltage automatically.

So I could have a 4.4 OC for light loads and under heavy load it'll drop back to 4.1 with stock voltage.

Quite a handy feature, especially for air cooling.

well if it goes for bad 5820K mentioned here before mine was so poor i decided to swap it for Ryzen !!!!! Maximum stable [email protected]. 4.5 unstable no matter what volts i threw at it. Would not boot up with 1.25 strap so max memory was 2666.

Basically my Ryzen @3944 is equal speed. OFC lost on this one also as its highest clock that it can pass Realbench for infinite time or ibt for 1 hour. Once i pass 3950 i can put extra 300-400mv and program will crash :/

Have you tried running IBT for longer than one hour or only stable for one hour?
