Damn.. More nice kits from gskill.

Is there a test/comparison that I could have missed showing, purely for gaming, if lower cas is better than high speed? ie, should i go for the 8000 CL36 or the 6000 CL26 kits to get the most out of it? atm, my understandin is lower cas better for games/x3d, but could be wrong.

I guess all new high-end kits would be the same now, because G.SKILL is using a new PCB now. This PCB was originally developed for CUDIMMS, and seams to have 10 layers. Now they are using this PCB on these new UDIMM high-end kits.

I believe this new PCB is the real reasons for these good results. Because they had many high-end kits before, but they just pushed voltage and overclocked the same A-dei on the same PCB. That was a silicon lottery as any other A-die kit, actually. But now this new PCB is a game changer.

Thanks, indeed seems that they are probably very close. But because they are not necessary "cheap" kits and not that easy to get, as i'm about to press buy, i rather get what could be the best. I'm leaning towards the 6000 CL26 kit at the moment.

You are welcome :) Yeah, these are really interesting and I've been looking at the 2x48GB 6000CL28, but they are not cheap, at all. In this round, they are in business of selling expensive high-end EXPO/XMP profiles, you know. ;)

But the big question is, are they going to use the same PCB on all kits now? I hope so, because I doubt they would keep tow assembly lines for PCBs. So they will be forced to use the same PCB on cheaper A-die kits too? In case, we can buy those cheaper kits, with the same PCB, and overclock it manually.

Interesting. If the other CCD is keeping it back, then a 9950x3D with a proper tuning, a good per-core CO and Curve Shaker, should beat the 9800X3D too, because that would isolate any slow CCD or core too. I was trying to say this to @cta62 last night too.

The point is it should with higher clock speed. I want to see the 9800X3D PBO vs 9950X3D PBO because while the 9800X3D can hold 5450MHz I am not sure the 9950X3D will be able to hold 5750MHz at a safe voltage. If that is the case then there is no point that it can clock higher if it does not hold the clock speed for more than a few seconds. I watched a review where someone disabled CCD 1 and was gaming just on CCD 0 and even then the clocks were bouncing all over the place from 5550MHz down to 5350MHz.

i was extraordinarily transparent with my results. I literally included multiple photos documenting the cooling solution - not sure how much more clear I could have been. and i'd love to get cherry picked hardware - could you help me out with that? im stuck buying retail like a pleb :(

it wasnt directed at you perse. i know you legit..

IE
Theres in house asus boys here for example.. and theres one whos posting underambient stuff.

That is because what Skatter Bencher posted doesn’t appear to be correct. I am only seeing the cache CCD top at 5550MHz with PBO +200. It is only 100MHz more than the 9800X3D and not 300MHz. This is with CCD1 disabled as it being enabled doesn’t make a difference here. I am also seeing the same on all review sites.

Yeah I can confirm the fMAX on the cache CCD with PBO +200 is 5550MHz and not 5750MHZ on the cache CCD which is why the performance is so close. What Skatter Bencher has is incorrect. The cache out of the box is max 5350MHz. This makes sense as the 9800X3D I had would hit a wall around 5550MHz overclocking as well. What @domdtxdissar has on his ES sample is what the final samples are as well. There is no special magic here just an extra 100MHz.

Im pretty sure probably using eclk

I can hold 56-57x on the 9800x3d specially dead space remake out of all the games i have is the hardest hammering the cpu even over warhammer 2... i seen it over the 110watts+ on dead space

AIDA64 is a true joy spoiler. :) Today it failed after 3h of testing. This test was run with PBO -15. Next move is to try eCLK 100 (instead of 100.5) and then maybe PBO -10 and or tRFC 448.

I have made it my go to for stability. Core Cycler for 1T, OCCT, finish it off with Aida64. 24hrs of each. If you cant pass that then your not truly stable. 24hr of Memtest5 also.

They were going for $699 like everywhere else. Got home with mine from Micro Center. They had and still have tons of stock. So far lots of clock stretching out of the box. Lots of bouncing between 5550MHz and 5350MHz in a few games that I tested. Going to try PBO and dial in a negative CO offset and see if that helps. So far it runs at a higher voltage than my 9800X3D did. Doing this all with CCD 1 disabled. More to come soon.

How much were they going for on Amazon? Grabbed one from Scan myself, amazon and the AMD site were out of stock by the time I could order

My price was the same as most everyone else's ($699 USD) but on Amazon I can leverage 0% financing for 12 months. Besides, I had to buy another motherboard and a couple accessories so I could get this thing built and running over the weekend.

It's really selling for $699 USD, but the price is too close to 9800x3d and 9950X for AMD's own good. Nobody would buy any of these any longer.

This is going to affect the price of the whole range, I guess.
