They did ship the memory. New ram kit will be here Monday! I did some research on the G.Skill 6000c26@1.400v and G.Skill 6000c26@1.450v kits. And read so much about both kits from the pro’s and extreme binning enthusiasts. So it’s literally just luck of the draw, but the 1.450v kit can be better than the 1.400v kit, and the 1.400v kit can be better than the 1.450v kit. But the 1.450v kits are not lesser than the 1.400v kits by default. But either kits are both equally binned and it’s completely luck of the draw with winning the memory silicon lottery with either kit. Some kits can do 6000c26@1.330vdd some need slightly more.

So 100% stability tested on all three tested 9950X3D2’s. (1) 2167fclk@6000c26 SP117 (Ultra Weak IMC) (This turd already went back) Ran this one on the Dark Hero open box I had. (2) 2200fclk@6200c26 SP118 (Cores use the least power of all, ultra efficient highest clocking chip, it uses the least pwr and has some very low temps. (I actually may have just stabilized 6400c26@1:1) I noticed a discrepancy in screenshots. The auto CLDO VDDP voltage was running at 1.150v stock, my other chip with the strong IMC will automatically run this at 1.045v. So I changed it on this one, and now it’s running VT3 at 6400c26 1:1. 🤷‍♂️ (3) 2167fclk@6400c26 SP118. The chip has such an easy going IMC, it’s just hard not to love it. But the cores don’t run as high although it’s still very good. I’ll probably be keeping chip #2. Further testing will be done with new G.Skill 6000c26 ram kit. Finally a high binned kit to test!

Nice kit! Ram is expensive! These prices are becoming normal is all, and something like that $595 price tag for 8400 G.Skill sticks feels like a good buy. For anyone interested, there is another kit just like @Mr. Fox bought on Jawa.gg they have a make an offer option. $650 OBO. https://www.jawa.gg/product/133577/gskill-trident-z5-rgb-ddr5intel-xmp-ddr5-8400-cl40-48gb-2x24gb

I was happy with the 5090FE for its price tag and base level 5090 performance. It was only $1,999.00, not even $1,999.99. 😂. So for that price tag it’s really good. I had it apart too many times and it held up great, but I was super careful. I didn’t like that I couldn’t flash the bios. But then again, my 5090 Astral OC runs the original stock 600w bios and it’s not even shunted, but I have tried the XOC bios once. I’m so much happier with the Astral though, I can’t exaggerate that enough, even though the Astral was $3700. It’s just a far better GPU. Performance is significantly better on the Astral too compared to a stock air-cooled FE. The Astral is freaking massive, and I do not like and would not trade for a 5090 FE. 😎

I ended up getting that kit just like you had previously. Amazing deal! Heck yes! My rams are sweet, but dang they need the JUICE! But now that I’ve tested the Corsair kit, and now my G.Skill 6800c34 kit. I’ll hopefully be able to fully appreciate the bin. This kit is a G.Skill 6000c26@1.450v (2x16GB) @electrosoft You ever buy from MBPC.GG? Looks like a small shop that sales used premium parts. They had a 6000c26@1.45v kit listed for $439.99, I used a -$10 off promo and got it for $429.99. https://mbpc.gg/products/g-skill-trident-z5-neo-rgb-32gb-ddr5-6000mhz-cl26-36-36-96-desktop-gaming-memory-ram-2x16gb?variant=53407464554785&country=US&currency=USD&utm_medium=product_sync&utm_source=google&utm_content=sag_organic&utm_campaign=sag_organic&gad_source=1&gad_campaignid=21505374951&gbraid=0AAAAA-CjMDB6Y2qkjRbGAWsMtZp-CYEda&gclid=EAIaIQobChMI3LDl4ZjelgMVujgIBR0AHjBcEAQYASABEgKr6fD_BwE

Man, while I am pretty happy with my G.Skill 6800c34 XMP kit. As you can see they scale with voltage, and they at least do the job with some voltage. Which is great. But they just can’t compete with these fancy/elite 6000c26@1.400/1.450v kits. There is a kit that’s really interesting me, I saw some people running the 2x32GB 6000c26@1.400v Gskill kits. And they’re running 6400c26 tuned timings with merely 1.470v 😂 It looks like the 2x32GB kits seems to scale a tiny little better with less voltage than the 2x16GB 6000c26 kits do. Has anyone tried dual rank performance on AMD? I know I’m all in to 1:1, I’ll get bored with it sooner or later and move to 1:2 😁

😬 It seems like the jump from 6400c28 to 6400c26 needs significantly more voltage, I am using 1.700v VDD currently. Anyone else try this profile before? What sort of voltages did you require? I do not know why, but for some reason I do like the 2167 chip #2 better, the memory controller is more fun to play with. I will enjoy it for another 1-2 days, and then I will pop Chip#1 back in for 2200fclk and more testing! And if I find myself where I cannot live without Chip#2, then we will go from there! lol. But 6400c26 is amazing to me. 1.700vdd is high, but keeping the 1.400vddq keeps temps realistic with a fan. (3) cycles on VT3 and sticks were 45c.

Here is mine all stock no tuning to the cores or anything like that, PBO is auto so I am not sure if thats enabled or not. These Gskills 6800's are fantastic rams. Running 6400c28 with 1.45vdd and 1.40vddq. They destroy my last Corsair rams!

That’s pretty amazing temps for an SFF! Can you tell me what sort of settings you run here on this SFF PC? Do you run a manual OC with this?

CPU#2 might be the keeper for me. It’s only 2167fclk, but the memory controller easily stabilizes 6400c28 (Fully tuned timings) 1:1 with 1.480v vdd. I maybe can drop to even lower VDD voltage. I ran TM5 for several hours, ram temps were 51-52c and it still held up even with 65k tREFi. (I was using a fan on the memory) I’m going to test CPU#1 again, but I don’t think it’ll be able to do the same thing with 6400c28 1:1 so easily. Even though it has a 2200fclk. I will move to some 1:2 testing soon. It seems like either chip will post and run 8000c34, but I haven’t stability tested it. CPU#2 can run it easier. Which makes me lean towards it being the better choice. I haven’t tested any kind of core overlocking. I’m just not really any good at it, so I’ve stayed away from it lol. But I suppose it’s time to dig in. I’ve learned a lot about ram tuning on them though. Just not really sure what to do or start with on core clocks or CCD clocks and voltage etc, or load line etc. 6400 1:1 c28 performs STRONG. Just a little bit slower than 8000c34.

Oddly enough, I was trying @Mr. Fox 8000c34 bios settings, and CPU#1 could not run the 1.480V VDD, it required 1.500 VDD to even post in bios. Well CPU#2 works fine with 1.480 VDD. So IMC strength is definitely there, and seems to factor in your ram ability as well.

So, I was worried this would happen lol. I am testing the 2nd 9950X3D2, and it has a “Superman” IMC. Even stronger than the other one. This one runs 6600c30 1:1 without any fuss, but only 2,167 FCLK. So now I have a choice to make. #1 (9950X3D2) 2200fclk@ 6400c28 1:1 Easy Mode SP118. #2 (9950X3D2) 2167fclk@ 6600c30 1:1 Easy Mode SP118. 🤔

I cannot run 1.480v VDD, but thats alright. When I run R23 it hangs the whole system. I’m not really sure where to start.

Thanks! It works! I copied all of your settings. Only thing I changed was, I flipped the CCD0 55.50 and CCD1 55.25 etc, and I ran 1.500v VDD mainly because I am not sure how good my ram is, I think you had the 6000c26 sticks. But I may try 1.480v now. Very proud of this Intel GSKILL 6800c34 ram kit right now. It has impressed me so much!! I’m absolutely thrilled. Its not a Expo kit, so it runs DCPO, but they seem like an amazing bin.

So far I have been strictly playing with 1:1 memory tuning. 6400c28 is completely solid even with 2,200 fclk. I think I may even can stabilize 6600 1:1. But it starts to show IMC limits at 6600 (1:1) I just tried 1:2 today for the first time, DDR5 8000 1:2 posted up first try. Even with only 1.400v VDDIO. There was definitely something seriously wrong with my last setup to not work. PS: These are my setting below. I can't seem to get my latency down much. I am wondering if its OS related at this point. I even tried some manual Nitro Path settings. I am on a really old bios 1401 from 05/2025.
