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

very hard to damage a CPU like that. They must be knocking it about. god knows what dmg they have done so not worth the hassle and you have clearly made the right decision.

The seller clearly was trying to pull one over someone as he/she must have realised the dmg and the repair done only made it barely functional so they decide to sell and cash in

It's on it's way back guys but man, what a couple of crazy days of anxiety.

I was given a pre paid label to use. It has the tracking number on it already so it's just a case of taking it to the post office to drop it off. We have a mail room at work which works in conjunction with Royal Mail I took it there and handed it over to one of the guys. Later that night when I try and track its whereabouts - "Sorry tracking number not recognised or invalid" eh what..

It's finally updated to "progressing through this network" two days later. I was starting to panic like crazy as I didn't have a receipt going through the mail room at work.

Lesson learned

don't ever buy a CPU on eBay without seeing the underside of it too.

Anyway, this weekend will be fun

Glad you're getting that sorted

I love that x99 IHS's look like something that just fell off of Robocop

No way is that normal.

It's better than my worse 5820k in the world. Custom water, EK Supremacy EVO block + d5 pump + EK360 rad with corsair SP120 fans. high 80sc @4.3ghz 1.325v.

Realy did lose the silicon lottery on this one

My 5930k does 4.4GHz @ 1.25v and sits around 65°C at full load with a RVE Mono-Block... and that was with 2 * 980Ti in the loop :eek:

I did tell you it as the worst 5820k in the world. Its not like it a bad contact issue, the water does get very warm/hot.

The only thing I could do is Lap the CPU and or waterblock to see if that helps.

Those temps are pretty awesome String

This 6800k is sitting idle in the low 20's, I'm seriously impressed so far and I've only just loaded into Windows. A good 10-12c cooler than the dodgy 5820k under the same Cyrorig H5 air cooler.

I'm about to have a play and see what it can do. Wish me luck..

Thanks

I love the look of it too. It really does look like a bit of body armour or a helmet. As far as looking awesomely futuristic I'd give it a 10/10.

I'm not sure if that 5820k was just dodgy but the temps are already 20c lower 10 mins in to RealBench stress test :eek:

~>Dg<~ · 23 Mar 2017 at 21:59

could be my 5820k @4.6 idles at 30c on only a antec aio and max 65c.

Ayahuasca · 23 Mar 2017 at 22:51

A 5ghz 5820k that's stable in everything at a voltage and temp that won't shorten its lifespan considerably is pretty much a unicorn.

Mine will do 4.7 at 1.329v, after this it requires way above 1.4v for 4.8ghz.

queeg · 23 Mar 2017 at 23:38

my 5820k @4.4 with ek asus monoblock 1.25v idles at 26-30 peaks at 62 that's with a 980ti in the loop I think it will go higher but have never tried was happy with 4.4 and no noise.
has anyone got one of these to 5ghz on water not ln2 or something super exotic

Bluntwrapped · 24 Mar 2017 at 08:42

Some nice 5820k's there guys. This 6800k is looking great so far. It's running so much cooler than the 5820k I had.

I ran out of time last night but it looks like 4.5GHz is possible with just a bit more than 1.3v. I'm able to boot into Windows with 1.25v but crashed when running RealBench. Booted fine at 4.6 with 1.3v, im guessing it'll take 1.325v or slightly more to get it stable.

I'm going to shoot for 4.4 with 1.275v when I get back from work tonight, I'll take it from there

Hey

Great stuff mate, let me know how you get on. I'm interested to hear how it goes for you.

5 o clock cant come quick enough! I'm desperate to get back home and spend more time on it.

NegatronBear · 24 Mar 2017 at 17:39

Jealous, I desperately need more cores. Glad it worked out in the end

tyler_jrb · 24 Mar 2017 at 17:58

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

Fwiw, whoever soldered that cap back on has done a top notch job - colour me impressed!

I spit on that soldering quality I say . Hes left flux residue and its kind of blobby. Looks like large iron and/or low temperature. 6/10

I mainly only hand solder down to 3216 though done a few SSOP chips, not overly impressed though I've seen far far worse. (Though shouldn't speak too loudly as my last project I was persisting with the bit in need of replacement and made a bit of a mess).

hardkore · 24 Mar 2017 at 19:03

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!

Don't get me wrong I've seen some garbage in my time but OP's cpu is not up there with them. It will do the job tbf.
