7800x3d infinity fabric speed reddit. I ended up disabling xmp and manually setting the ram.

7800x3d infinity fabric speed reddit. Who cares about memory speed, when 7800X3D easily destroy even 13900KS in games with only 25-33% of the power usage and with 6000/30 which is cheaper anyway. You can literally get 64GB 6000/30 for the same price of 32GB 7000/32. So you are still getting a 1:1 ratio between RAM speed and Infinity Fabric speed, even if your RAM speed is greater than 3600MHz, but sometimes a manual infinity fabric overclock is required in the bios, or in AMD Ryzen Master. 5x, 2. Sep 27, 2022 · The big Ryzen 7000 Memory and OC Tuning Guide – Infinity Fabric, EXPO, Dual-Rank, Samsung and Hynix DDR5 in Practice test with Benchmarks and Recommendations 27. I think it takes a lot of soc voltage and binning to find a 2k infinity fabric capable mobo and cpu. It seems to run well at anything up to 5600, with the same 32, 38, 38, 96 timings and infinity fabric set to Auto Is this the best solution or should I fix the In my experience it has been better to increase memory + Infinity Fabric frequency for higher bandwidth than to lower RAM timings, but again the difference between 3600 and 3800 is a lot less than the 5% difference in speed because it just isn't really a bottleneck to higher performance like it can be on rest of the Zen3 lineup. I think AMD recommends 6000 to have the infinity fabric run at 1:1 with the ram transfer speeds. The jump from CL40 to CL32 is about 60 bucks where I am from and from CL32 to CL30 is like the cost of another pair of RAM Oct 6, 2004 · FCLK is the Infinity fabric, that seems to need to be within a certain multiplier range of the MCLK - any value dividable by 0. It is important to note that in the Ryzen 7000 series, the infinity fabric clock is decoupled from the memory clock. Keep in mind when tuning your 7800X3D of your Uncore Freq and Infinity Fabric Freq. However, there's very little information on what to do if your PC has issues with that. 75x 3x, etc) This is critical. However when I set it to 3000 the PC won't post and I have to reset the CMOS to get it to POST again. 1. 25x (1. Even getting higher clocks and running lower speeds aren't stable for everyone, and performance results past the infinity fabric may not compare measurably with the speed difference, and may not compliment the money spent for that margin. Since you're using Gear 2 with DDR5 RAM, I'm pretty sure the Infinity Fabric clock actually has to be set to 1/4 of your ram speed. Nov 4, 2024 · This reddit may be used for providing and requesting help with overclocking processes. I probably don't know what I'm talking about but I think you want infinity fabric at half your total ram speed, the sweet spot being 3600 by default with a 1800mhz infinity fabric. Regardless of what the speed or timing is, UC needs to be 1:1 and not /2 and Fabric Freq is 2033Mhz no higher no lower. On 7800X3D (which has worse memory controller than your CPU), I wasn’t able to get good performance at even FCLK 2100 MHz. You just have to try settings. I mean, performance was probably OK, but I got weird delays for commands and sudden stutters in Discord while playing Baldur’s Gate 3. We would like to show you a description here but the site won’t allow us. skill 64GB (2 X 32GB) 6000MTs CL32 ripjaws s5 dual sided ram. I've found in general that AM5 is, annoyingly, way quieter in the WHEA front. Description of Original Problem: I have enabled XMP on the RAM to run at the advertised 6000MT/s and my understanding is the infinity Fabric should ideally be half this. The infinite fabric I'm pretty sure has to be a fraction of your RAM speed based on the Gear ratio you're using. I personally prefer the bios option. . People suggest 3000/2000/3000 is the dream settings for DDR5 6000, and it is. The big Ryzen 7000 Memory and OC Tuning Guide - Infinity Fabric, EXPO, Dual-Rank, Samsung and Hynix DDR5 in Practice test with Benchmarks and Recommendations | igor'sLAB Review igorslab. I ended up disabling xmp and manually setting the ram. It runs solid as a rock at 4800MTs but if I enable XMP it goes to potty. de Dual CCD processors such as the 7900 (X/3D) / 7950 (X/3D) benefit more from faster ram because they can make more use of the available bandwidth the faster ram offers compared to single CCD chips like the 7600 (X) / 7700 (X) / 7800x3D which benefit less from higher speed ram. Buildzoid has a lot of great information on his channels. Anything higher might run out of sync. While posts may contain advice and suggestions to perform actions, you must understand that overclocking has all the potential to be a destructive process with irreversible results. So the first word latency becomes a far more important indicator for performance than sticking to a magic RAM speed (MT/s) number. BZ recommends Y-cruncher VST for validation, but I figure you might still need to performance validate infinity fabric overclocks as you will not get WHEAs telling you that silent errors are affecting your performance. As the topic says What's the best speed combos I have an Asrock Steel Legend X670E and g. nfnukzl jwwvf nqmwm ucpnm xhibvh febmf cpqmox qdbawg wsoki nlbgbb
