I9 9900k

Bit on the toasty side at 90c :p. Waiting for delid kit and all the bits.

But so far very happy. 1.4v in bios (1.35v under load). However this hasn't been tuned in yet. I suspect it could do lower voltage. 5.4ghz not stable however. Will be tuning in over the next few days.

Revisiting my overclocks to get an idea on what are the lowest voltages required for a given multiplier, will be running Aida64 non FPU/AVX, being as I don't do anything that utilises these instructions. ;)
5.1ghz

Me too, I’ve gone back to my nickel Supremacy EVO which in my opinion is better quality, bigger springs, thicker clamp plate, better microfin machining.

Also the mobo backplate that came with it wasn’t even threaded, just drilled holes.

After a bit of testing, doesn’t perform as well as my original supremacy block by quite a bit so going to swap back to that tomorrow and probably return it back to ocuk due to the non threaded backplate. Just doesn’t seem to contact right on the IHS.

I snapped up a 2nd hand 9900k 6.8-9ghz (ln2) from 8 pack which arrived today so got that to fit and test tomorrow when I get home from work. Also a delid rockit kit and copper IHS ordered so I can do that in a week or so.

Nice scores btw! If mine comes anywhere close to yours, I’ll be happy :)

I changed from Evo to the Velocity and temps were about the same. Within a degree of each other. This seems to correlate with reviews I read around the time. Maybe there has been a batch with bad mounting gear? I read someone else get a 7 degree difference between the EK and an Alphacool. This also tends me to think there was something up with the mount as 7 degrees on Intel chips at the top end of wc blocks is a multi generational gap. 1 degree is seen as a big jump at the top end.

I’m thinking the same. 5ghz before was around 90+c.

Now can run 5.3+ at lower temps.

Everything is just running much nicer with the evo. Which is solid nickel so may have something to do with it. However the velocity just didn’t seem to clamp down as hard and much more a pain to fit with shorter lower nuts and springs.

Now idling at 25c where previous it was into the 30s. And I’d say several degrees from load at least. I’m guessing just poor mounting.
 
I've had 2 Ek Velocity blocks, each used with their own mounts and they were both the same in terms of temps.
Cleaning the block helped some but it really is tough to mount with a delidded 9900k even with the Die Frame.
In addition to the mounting issue, one of the jet plates had iffy machining which was obvious when compared to the other while they were being cleaned.

On the plus side they do look amazing imho, but looks alone won't bring temps down so right now I am looking around for up to date reviews of other blocks.
I think buying a replacement is going to be a shot in the dark anyway because the EK velocity wasn't that bad when reviewed from what i have read, yet it doesn't seem to perform where the reviews are placing it.

I'll give the velocity another scrub and try again with the replacement Die frame when it arrives and perhaps temps will be better. However, I won't be recommending the block to anyone going forward.

For Direct Die mounting the Velocity falls short IMO, my trusty Raystorm Pro has a much deeper body so unlike the Velocity it doesn't sit straight on the nuts on the mounting posts which gives you room to tighten down properly, which gives a very good contact. JMO. ;)
 
Upping the cache ratio now to the 48 multiplier, my chip can do 50 at least, 52 core ratio. Still using Aida64 non FPU/AVX, I don't use it so what's the point in my opinion. Load voltage 1.243v, max temp on one core 67c, lowest core 61c. Average core temps between 52c and 59c. Package temp max 67c, average 63c. Will keep tweaking. ;)

Very nice, are you aiming to keep that oc (or as high as reasonable) as your daily once delidded?
What kind of cooling are you using for that?
Click to expand...

Just on my loop which is 3x360mm rads. Will be running at 5.2ghz (0 avx) for 24/7 usage, 4000mhz on the memory.

Load voltage 1.275v, around 200w, 80c on prime95 small fft's. Realbench around 75c.

Not sure on delidding yet. Will decide tomorrow once all the gear arrives.

Snap!!! Same as my 24/7 oc. I mainly game :)
 
Hey OcUK, just wanted to say a quick thanks. I bought a 9900k a month ago (OEM) and thought I might get a bad/average OCing CPU (where exactly do OEM CPUs come from?).

I've just attempted my first OC with this CPU and I'm hitting 5Ghz comfortably. AVX: 2 and still adaptive Vcore hitting 1.27. This allows my whole cooling to be kept on the silent setting, which is my main priority. I still need to do a few test before stabilising the Vcore, but initial test are promising.

Thanks!
