Intel Core Ultra 9 285k 'Arrow Lake' Discussion/News ("15th gen") on LGA-1851

[Nevakonaza]

Just put my order in for the 265k as it dropped to under £350. Looking to see what motherboard and RAM to grab now,

Great choice,I highly recommend the board i went with "Z890 Aorus Elite WiFi7"

Great board, Doesn't break the bank and has a ton of features.
Worked straight out the box no issues, I have 6000Mhz ram though not sure how it handles faster ram.

FYI 6000 is below the base of 6400 on the memory for Arrow Lake.

Up to 8200/8400 maybe the limit on 2 DPC boards

I've gone with an Asrock board (Z890 Taichi Lite) as there was a sale on and a cashback too which has worked out really nicely. The only thing I paid full-beans for was the CUDIMM 8000mhz memory which I'm ok with considering the discount on the CPU and motherboard! I was tempted by the Aorus Z890 as I've had some great Gigabyte motherboards over the years.

It depends man i was in the same boat as you.

If you use a good case then a D15 should be good on a 265k stock (intel default setting) but...the moment you start using within the bios things like "performance" and with a higher PL1 and PL2 setting or do a manual OC then these things become pretty hot as ive seen in reviews and user feedback. Arrow Lake loves high speed CUDIMM (there are rather big gains at the sweet spot of around 8000 to 8800mhz) if that is what you want then CUDIMM is the way with if you can a 2 dimm slot mb there is one out there for a decent price but it's ITX ie The Asrock Z890i Nova.

I wanted to use a D15s it can fit inside a Lian Li A3 matx however the case is small. So i checked for a proper AIO 360 i then decided screw it due to the sound of the fans on those things at higher loads. And im not new to custom watercooling i have everything i need except for a cpu block which i already ordered. If you intent on using higher performance within the BIOS or do a manual OC then i would def go with a good 360 or 480 AIO if your case can handle it.

Cheers man, ended up grabbing the Arctic Liquid 3 360mm as my case supported it so I thought why not!

My understanding was that the official spec didn't change for UDIMM (still 5600) and is 6400 only for CUDIMM, but can't find any confirmation anywhere.

This is correct. 5600 for UDIMM and 6400 for CUDIMM. I went with 6400 UDIMM though because I need and want 96 GB of RAM and don't want to spend the money on 48 GB CUDIMM that would also get me a 96 GB UDIMM kit.

Thats a great AIO and has a thicker radiator then most AIO's out there that should keep your 265k DEF in check incl some mild OC. 8000mhz + potential OC is great should be able to do 8400 to 8600mhz if need be. However i read that DDR5 can be unstable at above 55c, 55c....yet others have no issues at all. Me...i will put a custom RAM cooler inside my small Lian Li A3 already started working on pesky cable management on those Lian Li ST-120 ARGB fans and the look on tubing etc + custom RAM cooler just in case it will lower temps by around 11c to 15c:

Great choice on the mb the Asrock z890 Taichi Lite. I my self on my MAIN gaming rig have a Asrock Z790 Taichi + 13700K + MSI RTX4090 Gaming X Trio all custom watercooled with read carefully 2 x 840 full copper rads from Aquacomputer AMS rad line, so i have 12 x 140mm rad space cools very good more rad space then a MO-RA3. 12 x 140 fans running at 600rpm = dead silent. I am liking the Asrock brand mb main objective is stability, reliability as i have seen feedback from people. Screw Asus they went downhill like 7 or so years ago with QC. The only brands i trust with Intel based mb = Asrock or MSI (and also EVGA mb's). And for GPU's only MSI (they tend to use high quality pcb parts ie chokes, fuses etc) used to be EVGA god i miss EVGA gpu's!

Do share your benchmarks and temps when your build is done. Have fun! Cheers.

Do you guys think id see much improvement going for faster ram with my 265K? i currently have 6000 Mhz but they're good CL30.

Cudim worth it? How do you even tell what are Cudim as looking at DDR5 on OCUK i cant see any that stand out>?

 

[Glanza]

Took plunge and got the following:

265k,
Kingston CUDIMM 8400 Renegade Fury,
Intel Z890 Maximus Hero (got a good price on this from one of our suppliers) otherwise was going to go with the MSI Carbon this time around.

 

[Vimes]

@Glanza is this in addition to what you have in your sig or as a replacement..?

What would be your cooler..?

either search for cudimm or go into ddr5 7200+ section sort by price and they'll be at the top, Kingston or Crucial is all OCUK stock currently. I went with the Kingston as I hate having to install icue just to change the RGB on Corsair sticks

Addition / potential replacement if happy with it. Was having a few little niggles with the 9800X3D build and wanted to see how these new Intel chips performed (I game at 4k 120hz) so not chasing the huge numbers that YouTubers keep stating as to why you need a 9800X3D.

Cooler used on both is this (black version):

My basket at OcUK:

• 1 x Phanteks Glacier One D30 420mm White RGB All In One CPU Water Cooler (SKU: HS-01U-PT) = £169.99

Total: £173.99 (includes delivery: £3.99)​

Ah, hope it works out for you. As a broad generalisation, I had noted some mention Windows responsiveness, and some with applications, in other words desktop use, and, at times, some stuttering with their 9800x3d builds. Then again, that could be related to many things I suppose
Don't really experience anything like that with my Intel build.

I am gaming a t4k with my 14700k and 4080, all is fine for my expectations and games that I run. I am not too bothered about the highest of frame rates, I am more likely to notice stuttering, perhaps 1% lows issues than I am higher frame rates.

I use a Arctic Freezer III 420mm.

I remember zip tieing a fan over my RAM on an older build I had a long time ago to keep the memory cool!

Yeah, the AIO seems great so far, really like that it came with a contact plate as well. I'm currently just getting everything set up before moving things into my case / swapping parts around but mostly so far all has gone well. XMP profile for 8000mhz CL38 worked without issue and I'm running a few different memory tests to make sure things are stable. Memtest ran fine, might see about OCCT and Karhu today as well - then I'll move things into my case.

I forgot how nice it was working on a PC with integrated graphics too, saved me some hassle of having to keep moving my GPU around.

Overall from having a bit of a play around this morning with installing everything and getting Windows configured to my liking it definitely feels 'snappier' (incredibly technical term there) and more responsive than my 5800x3D build and having them both alongside each other is quite useful to cross-compare.

Has 285k in the test

The benchmarks towards the end are interesting - but it does show that 285k is much improved compared to launch. Sitting second behind the 9800x3D in the majority of titles, only those where they absolutely go bananas for 3D cache does it drop behind the 7800X3D.

Impressive from the 5800X3D as well to still be in consideration considering the amount of 'newer' CPUs that have released since it came out 3 years ago! It's a shame they wanted absolute system parity in the tests with the same CL30 6000mhz memory on both the AMD and Intel builds, we all know that the 285k hugely benefits from faster memory.

 

[Rroff]

The 14900 performance in that video seems a bit off - closer to the 7800X3D in some cases than I've seen it while quite a bit slower in other cases where generally it wasn't far behind, albeit I've not seen how things stack up with the 5090 myself but it shouldn't result in it closing the gap in some situations compared to the 4090 unless there are some drivers/CPU changes with the 5000 series in play.

Weird it was crashing in Hogwarts legacy as well - there does seem to be some issues with the game and latest drivers if you have nVidia App overlay enabled at 4K but I've not seen it crashing at 1440p unless again this is something 5000 series specific that affects the 14th gen but not other CPUs.

 

[RSR]

I'd like to know all the details of the test systems, mainly so I can go and see

I've got the 5090 running on the 285K at the moment, and seems a 28% uplift at the mo

Thats great news that your 8000mhz XMP worked out of the box and you done some ram testing without crashes or BSOD you mentioned still have more tests to do on your ram. Feel free to post your findings after you done testing the ram more indepth. I wonder if i go with 9000mhz on a Asrock Z890i Nova itx it also will be stable but i guess it wont be probably 95% sure of that but i am aiming at 8800mhz hope that will be stable at that speed all that need to be done is tinkering with CAS.

I also read that gaming with the 265k and 285k is more smooth then with the AMD counterparts there are various YT channels conforming this when they used Ryzen 9 vs 265k or 285k (not talking about fps difference)

Nvidia drivers are in a bad place atm, they've now tried 5 times just to fix black screens
