    [Sammelthread] Intel DDR5 RAM OC Thread

    Hey! How have you been? What a good result with the new CPU. I can't contribute much from the CPU side, and I never had Klevv, but with my Gskill A-Die I achieved a MVDDQ connection in 1.38v to CVDDQ1.18v, but with 38-48 and SA 1.14. Now I am at 8200 C38-48, let's say without OC, but with good...

    Hi @Veii, Good morning! How have you been? I couldn't go straight to 8400. Tests with very low SA limited me. I was able to achieve the following as a halfway point. What I don't quite understand is why SA has to scale with frequency. 8266C38 MVDD 1.45 <-> <MVDD2 1.425 MVDDQ 1.38 <->CVDDQ...

    Hi @Veii, yes, I always change to LLC4. I used OC tool to read load defaults at LLC4 an AC_LL is around 0.27~28. Any change of VRM behavior like Extreme it changes the AC value. When you are referring to 0.65 or 0.6 is always at LLC3, right? I remember tibcsi setting a higher AC@LL4. But he has...

    Hi @Veii sorry to bother you with so basic question. When you are referring a cut supply is that setting AC/DC_LL right? Or if I set for instante Set Core by usage and limit 2 core to 58, 3x57 and the remaining to 55, for instance, it would be cap? I’m working with my VF, so compensating with...

    Hi @zebra_hun good morning there! I have in mind what’s @Veii mentioned above no cutting supply, so, perhaps I didn’t understand well, but if I could undervolt my VF curve well, I could compensate increasing ACLL. I’m actually running my 3rs 90min YC test for 8200 in the road to 8400. Step by...

    Hi @zebra_hun, I’m doing fine. Thank you! I had sent you in my last post #1,114 ycruncher while it was running at 54x and then many tests with the CPU at stock values, CB23, 15, 24 Do they work for you or do you need other ones? Do you have a screnshot of the new VF to see if they look alike...

    Hi @zebra_hun, how are you? I had worked very hard since Veii gave me some hits. I will put some results in a next post :) How did it go with the new CPU? What is your VF Factory Fuse? My biggest problem is on the CPU side due to my lack of knowledge with Intel tuning. I put more focus on mem...

    Hi @zebra_hun, thank you so much for the test! Below a lot of pictures for you to compare. I guess you will find Vmin better than me and how my CPU is running. I'm far away from an expert, but I learn fast :) I have been back with Intel since September of last year, before that with AMD since...

    Hi @zebra_hun, thanks for all your information! I just did a lot of test to compare with your screenshots. Indeed, as I have an issue with the "Trained" SVID Behavior, which is why I can't run R15 Extreme or CB24 because I either have a crash or BSOD. Therefore, since I didn{t want to execute an...

    Thanks! I will copy your values to run Y-Chruncher. There was a debate in OCN that it should always be run unlimited, for short tests it can work (4 cycles), but for tests of 90 minutes or 6 hours, without a doubt your configuration is the best. I'm going to see if it generates any WHEA for me...

    Hi @zebra_hun, how are you? You're right, you have excellent cooling, I have an AIO with some good T30s, but it's just that. Since I come from a 13700kf that was very good for me, and I ran everything at 55x, with 25xW maximum, I never had problems of any kind. I thought that the 14900k with 57x...

    Hi @Veii! Thank you! :) no worries, I imagine you are busy, when you can. In the meantime I keep testing and learning. Meanwhile, I'm still running test. I guess the delta that I found VDDQ to VDDQ (150mV) it's good, but I need more tunning. Indeed, I just left again TM5 running (I passed 50...

    [Sammelthread] Intel DDR5 RAM OC Thread

    Hi @Veii, how are you? I took your recommendations but none of them worked. In fact, what surprised me is that in all cases I had BSOD, perhaps due to such a low SA both in 8000 at 1.12, and in 8400 while maintaining 8400. For 8000 lowering SA I set the parameters you indicated, it failed with...

    Hi @zebra_hun, how are you? You are doing an incredible job. I would love to know the methodology so I can help. I know that before CMDVRefUp was always used as an entry point, until Veii shared the CTL0 with us. How does the value you discovered help in practice? I don't remember now the...

    Hi @Veii, good morning! After trying several attempts at 8400 I went back to 8200 with the delta I had found and realized that the bitrate was not as consistent. I did a clear CMOS and YC failed in some iterations, from SA 1.165 I tried 1.5, it failed faster, I tried 1.17 and ended up at 1.18...

    Hi! Here they are my results of the new 2x24 Xtreem 8200@1.4v. As I learned from the best, the first thing I did was look for the VDDQ to VDDQ delta. Although the kit comes with 8200 38-49-49-84 @1.4v XMP, I tested the following voltages for 8200: VDD_mem 1.41 <-> MC 1.42 VDDQ_mem 1.35 <->...

    Yes, I was lucky really. I could just buy one CPU cause I have lot of custom taxes and shipping cost, so is hit or misss.. But I know I have a good CPU, I just need to work with my VF as you did. Now I{m playing with a 2x24 Xtreem 8200 with deltas. This mem kits are amazing in term of head...

    Hey! Congrats! I must confess that buying a CPU is like going to the casino. I think many buy it for that adrenaline rush to see if they get a good one. I must confess that the two processors that I bought on Amazon were excellent. I was lucky, but I never buy at launch. Likewise, in my case...

    Yeah. I've been reading the posts since last year, and in one you shared a drive. That's why I could see your name. Don't add you so as not to disturb. But there is nothing to hide :) I have a big part of my heart in Hungary. (Which I still don't know). I am waiting for some new 8200mdie to...

    Well, I tried, but it seems like they put some protection in the BIOS. I could read it with 0080. There should be some way to read it... Your VT3 results are very good, the Bitrate at 8000 surprises me. I think I'm at 1.40.. But I see that you have excellent cooling, which is not my case. That...
