Despite what some people have said here, the cheapest DDR5 ram isn't "garbage bin tier", the benchmarks tell a different story and its not much more expensive. for faster response and lower input lag. If PBO doesn’t yield much gain in gaming performance than stock should be fine. When you run 1 DDR5 stick of ram, it's like running 2 sticks of DDR4. Hard to tell where regular usage ddr5 will cap out at (basically the ddr5 equivalent of ddr4 3200/3600). I've seen (and I've been doing it myself) floored tRAS everywhere but actually wondering if it sweetspots at higher values. you could do cl28 with more voltage but difference in preformance is very small. First I was running 6200 28-36-36 but had to bump up to 26-38-38. Once DDR5 comes way down in price I'll get faster RAM then. I have definitely seen a lot of the things you posted in different spots like tRC, tFAW, and tRAS formulas, but wasn't sure. You can test the difference using PYPrime, but there isn't a lot of benefit. I remember back then, in the early months after Ryzen launched, when even just getting 3000MHz or 3200MHz XMP profiles to even boot with only two sticks of memory was hit or miss, let DDR5 has the worst latency of anything. 47V a couple days later and still pass Memtest86 without errors. Get the Reddit app Scan this QR code to download the app now - 2 x 16 GB DDR5-6000 CL30-36-36-76 (TRC 134, "EXPO 2") 1. If I do so I definitely would be willing to push the voltage farther but right now even at 1. Reply reply If I was going off my theoretical tras then yes tWR=tRTP. That said, i think 6000Mhz CL36 is the sweet spot for DDR5 right now. It doesn't matter whether you raise TREFI or lower TRAS or whatever. Motherboard is mid range Asus B760-PLUS and I used 4 x Corsair Vengeance 32GB ( 5600MHz CL40). DDR5 by far and it's not even close. That's why you get BSOD. SKILL Trident Z5 RGB Series CL34-45-45-115 1. But, if you compare equal capacity GBs with DDR4/ the price/gb is way higher. I just ordered a G. It's overloading the CPU and controller by forcing more information than it can handle. 42v SA 1. 35V Latenz (CL): CL28 RAS to CAS Delay (tRCD):34 Ras Precharge Time (tRP):34 Row Active Time (tRAS):89 32GB G. All Hynix can do 40-40-40-77-117 + tRFC 840 / tRFC2 640 / tWR 96 @ 6400 1. But what im not really sure about is if I NEED to disable the EXPO before i do those tweaks to the timings or if I can leave it on since its working fine and it tightens the primary timings fine and Then I upgraded from 32GB to 128GB DDR5. Learn to overclock, ask experienced users… I'm gonna describe the operation of DDR5 to the best of my knowledge. Wow, thanks for the long reply. tfaw，理应为trrdsX4即32，但，d5似乎不必遵循这条规则，可以设置为24，最小不能小于16 到底是32效能好还是更低效能好，不知 Maybe look at the mainboards supported ddr5 speed if you are planning on buying cheaper drr5 later. 32GB of DDR5 6000 CL32 is about $125. I purchased two "G. Recently built a 14900K system with 48GB DDR5-8000MT/s RAM. i can give you the best settings for that board. These very high end kits (7800+) will depend on the board and IMC you have, so they are not a guarantee (nothing over Jdec is a guarantee, but 7200 is in the realm of reason, 8000 is going to be hard to run) You don't save anything on the mobo, DDR5 and 4 models are either the same in price or $5-10 off. Skill Flare X5 For AMD Either way, 32gb (2x 16gb) 6000 CL30 is the go-to recommendation. When it comes to DDR5 especially, my suggestion is to buy something listed by your mobo maker's QVL (qualified vendors list). true. A memory stick capable of running tCL 22 at 6000 MT/s, but has to run tRCD 50, tRP 50, and tRAS 80 will almost definitely perform worse than 30-40-40-50 for the same timings. I know people say to run tRAS 28 but in reality running tRAS lower than tRCD+tRTP is just running the timing too low and it will miss clock cycles. But thats for central Europe, could be different elsewhere. The price difference is $20 for significantly better performance and reusability. The current Z690 boards and ADL CPUs may be perfectly capable of running DDR5-8000 or DDR5-10,000 when it releases, but we won't know until there are DDR5 modules at those speeds to validate with. So if anyone is wondering, here's my experience. It should be the same method for Hynix M-Die as well. If you're pairing Intel with DDR5 at the moment, you'll have to upgrade mobo after Raptor Lake anyway, at which time hopefully DDR5 price and performance is better. Is this crucial kit a good buy? [Crucial Pro DDR5-5600 CL46] No it's garbage. I’ve looked up the values and last number is the tRAS, but I’m not sure what that is because the explanation on the site I found didn’t make much sense to me. Skill Ripjaws S5 schwarz DDR5-6000 DIMM CL30 Dual Kit (120€) Voltage: 1. They reduce latency and often increase effective bandwidth by reducing bubbles of bandwidth loss, even though the ceiling doesn't go up. Although, from the leaks it seems Zen 5 is catching up quickly, AMD is allegedly aiming for DDR5-7200 for the server segment, that could mean 8000 MT/s or more Hi, so i am in the market for some nice new ddr5 ram and I am torn between 2 kits. One is Corsair Dominator Ddr5 6600 cl 32-39-39-76 The other is Gskill Tridentz5 6400 cl 32-39-39-102 The minimum latency result I was able to get so far is 52. The DDR4 specific stats dont work for DDR5 but the impact of timing change, value of FCLK and MCLK synchronisation for AMD platforms, latency enhancements etc. tREFI is the biggest single gain you can have but it makes the memory extra prone to corruption if it is too hot. I'm looking to buy a DDR5 kit and I hesitate between Corsair and G. Too low tRAS will just increase instability, and the Hynix 3GB M-Die generally doesn't like too low tRAS/tRC. Overall DDR5 is a better value. New platform is exciting, but also devoid of any information. Skill Ripjaws S5 DDR5-5600 DIMM CL28 Dual Kit (110€) Voltage: 1. Short version: Here are Zentimings, AIDA64 scores and PyPrime. You will also gain enough stability to *maybe* be able to run tCL30 instead of 32. Power Management. . Oct 6, 2020 · If we look at SK Hynix’s announcement of DDR5-4800, this could be DDR5-4800B which supports 40-40-40 sub-timings, for a theoretical peak bandwidth of 38. We both know that as DDR5 ages it will get faster with better timings. Leave the rest of the values on auto. you cant do over 6200 on the carbon. The memory controller outright ignores same-bank tRFC settings, that can have quite an impact on performance. 288K subscribers in the overclocking community. First, load a memory profile for say 6200 from your motherboard. When comparing timings on DDR5 RAM kits, do we only need to look at the first 2 digits to determine the latency, or are the following numbers relevant to its performance, too? Build Help I'm thinking of buying a 2x16GB Trident Z 6600Mhz DDR5 kit, with these timings: 34-40-40-105. I'm planning on pairing it with a 13500 and a 3060ti probably on a B760 MB. Also, I've heard that AMD's minimum tFAW value is 20 so may as well use that as well. I think tWR hard walls at 8 or 6, though it's recommended not to go below 8. Add to the fact that AMD's current gen socket is DDR5 only and Intel's next socket (which isn't too far off) will be DDR5 only makes the choice a no brainer in my mind. Plus Google tends to shove all the popular media on the front page so essentially useless to use for research. Lower tRAS likely won't have any impact. Tested to be stable at up to 65 o C SPD temperature. SKILL because I've always used in the past. To pass initially I was at 1. etc. I come across buildzoids timing tweaks quite a lot, a lot of people recommend his timings on hynix DDR5 memory so i thought lets give it a shot. I will post more about my experience at some point, but I have CMK96GX5M2B6400C32 running at 6000MHz C32, with Buildzoid's Hynix timings (but with tRAS 30), on a Gigabyte X670 Gaming X. The Kit you posted has at at stock XMP a read of 109 gb/s and a 58ns latency(In AIDA64). is the basically the same so you can get the knowledge you need right there. We would like to show you a description here but the site won’t allow us. Skill have shown off DDR5-7000 CL40 running stable on some of the higher end Z690 boards. And that's measured in ns so it's taking into account speed and timings. Is there a definitive guide for DDR5 tuning? Or can anyone advice on optimal subtimings for DDR5-8000 ? Yes, AMD expo and 7600x stock should get you great performance. There's DDR5-6000 CL30 for under $90. I have the same board and RAM (A-Die as well) as you, and I cannot run anything stable higher than DDR5 6600. 45v VDDQ 1. Then tRC should equal tRAS+tRP so 50+38=88. In addition, subtimings have a significant impact on performance. Does it really matter though ? For Hynix M/A-Die, tRAS can usually be floored to 28 without any issues. The goal of tightening timings is to decrease the latency. The effect is seen in the latency. Just 4 individual 32GB modules. 6ns, Windows 11 23H2. However, if i put in the exact same settings manually, it works fine. As for DDR5 - yeah, the DDR4 / DDR5 conundrum had me contemplating all over the place - DDR5 is overpriced right now and not very available - well, better than maybe a few months ago. For example, . Corsair is at 30-36-36-76 Gskill is at 32-38-38-96 They seem both relatively similar except for the tRAS which seems to have a huge difference. The same 4 sticks of DDR5 that the ASUS board couldn't run without a lot of manual tweaking runs right out of the box on its XMP profile with the ASRock board. I know DDR5 is in its infancy and all that… However, I am curious who is showing more potential this DDR5 season. 35v IMC 1. Skill's camp. A decent DDR5 kit is much faster than generic DDR4 3200-CL16. I remember that in the last days of DDR3 you could get 2400 MT kits for pretty cheap, whereas the new DDR4 kits had exactly the same 2400 MTs except with worse latency. 49V then I was able to lower to 1. Skill both at 6000 MHz. Skill Trident DDR5 32 GB 6000 MHz RAM kit that has CL 36-36-36-96, and I found another RAM kit for $20 more with CL 36-36-36-76, and I wanted to know if that’s Cas latency in and of itself rarely matters. I've tighten the timings and tuned secondary/tertiary timings from random videos and posts around internet. Even at 1. what is the best bang for your buck DDR5 speed these days? G. So based on that idea, if you try to run 4 sticks of DDR5, it's like running 8 sticks of DDR4. I was looking into the bitspower ddr5 water block and really considering it. Might be capped by the mainboards ability. All else being the same, more memclk or uclk always helps. But yes, you can buy cheaper DDR5-4800 today, and drop in DDR5-7200+ in the future. I believe the way the primaries work means you would want tRAS to be tRP+tRTP so 38+12=50. The thing iscorrect me if I'm wrong, I'm still learning stuff: tRAS is the time between a row activation and a precharge command - so is the min time a row can stay active. May 21, 2022 · 关于trrds，该参数代表了DDR5中的突发读取，最小设置为8，但是设置为4也可过测 但最小应该设置为8. You can also pay $10-15 more for DDR5-7200-CL32 that leaves the best DDR4 further in the dust. DDR4 low timings (ex. 25 to 1. Maybe try enabling PBO since you’re already OC’ing the GPU. Iv got my kit at 6200 30-37-37-28 1. 4815v VDDQ TX 1. May 28, 2023 · Interesting info on tRAS, I'll try to set it to the sum of those three values and see how my system behaves. The 6000 MT/S appears to be Samsung chips (according to ASUS QVL) but the 6400 MT/S is SK Hynix. Ddr5 performs better in most games but you would need to buy expensive ddr5 to make the difference. As for tWR, tWR isn't an actual timing register on Intel. All things overclocking go here. Currently running 6600 30-39-39-30 at 1. My point is that currently (and likely for another year at least) DDR4 is faster than DDR5. It’s true you can match DDR5 performance with highly tuned DDR4 samsung b die but these kits are much more expensive than DDR5 kits, and it’s not a fair comparison at all as DDR5 can also be tuned in a similar way. After extensive testing i managed to set up timings to get best performance i could out of this ram kit. There is another rule for ddr4 that might be worth testing it wil probably improve bandwith, tcl+tRP+tRTP-2=tras I thought minimum twrrd for 4 dimms was 3, twtrS will likely need to be 4 maybe 3, twr can be 2x tRTP - Crucial RAM 32GB DDR5 4800MHz CL40 Laptop Memory CT32G48C40S5 - Kingston FURY Impact 64GB (2x32GB) DDR5 5600MHz CL40 Laptop Memory (KF556S40IBK2-64) Let us know if you were able to get the G Skill working. Nov 5, 2022 · Here is how I got my Hynix A-Die DDR5 stable at 6400MHz with the below timings. I was told that low means better on that one. Anything > 6000 c30 has a reasonable chance of being M die and obviously the higher bins are guaranteed M die. If you fix the DDR5 kit bad subtimings on a UNIFY-X you could get DDR5-6800 CL32 with a 50ns latency and absolutely bonkers performance. These DDR5 issues of not being able to just stick four sticks of RAM in, set XMP, and have it boot kind of give me flashbacks to early Ryzen memory compatibility. May 28, 2023 · Another trick is to type in all loose values with high voltage, overclock to the desired freq and work your way down. I just preordered the EK direct die upgrade for my velocity 2 waterblock and might grab the ram water block and install both at the same time. Buying new DDR4 is stupid for new 4x16GB Corsair DDR5-6000 30-36-36-76 ‎CMH32GX5M2B6000Z30K Totally acknowledging the whole "the 7800x3d runs 4 dimms at ddr5-3600 by default so that's a bit of stress on the IMC!" So where am I? EXPO 1 doesn't work. Until now, all previous generations of DDR memory received its voltage, pre-regulated, from the motherboard. The board even had no trouble overclocking the RAM from 5600 to 6000 MHz with me only barely having to run up the voltage; 1. Posting my update since I didn't see a lot of 14700K posts with 128GB builds. there wasn't a considerable margin for optimization. Yeah, the Zen 4 DDR5 memory controller is not the best thing in the world. The problem is I don't think timings are at optimal values. Now DDR5 has either "normal" ECC sticks, equal to one of last generations, or one can buy much cheaper on-die ECC sticks. 4 GB/s per channel and a single access 32GB of DDR4 3600 CL16 is around $95. It doesnt get that much cheaper when buying 5600 and it does get a lot more expensive when buying anything over 6000. I have 2x24GB running 24/7 at 8400MT/s 38-49-49-56 VDD 1. That DDR4 kit has maybe 58gb/s and ~50ns. 45V. Don't think that'll give you what you want, but it's a primary timing that can likely be pushed quite lower.

PSU: EVGA P2 850W There have been an excessive number of people reporting an inability to hit their rated EXPO/XMP speeds with DDR5, myself included. For AM4 it was well known that slow RAM held the CPU back "significantly", while on Intel this wasn't that big of an issue, but I'm having trouble finding any infomation about how this fares with 13th gen/Zen5. 32GB G. Also my point isn't that DDR5 isn't going to surpass DDR4. 35V Latenz (CL): CL30 RAS to CAS Delay (tRCD):40 Ras Precharge Time (tRP):40 The FCLK's theoretical max bandwidth is equivelant to dual-channel DDR5-3600 (at spec) or dual-channel DDR5-4400 (at a 2200 FCLK OC). While QVL ram wasn't the biggest issue in DDR4 and earlier days, DDR5 seems to be pushing memory controllers to their limit and it can be hit or miss getting high speed ram working with any stability. Other than timings, you could try raising MEM VDDQ and CPU VDDIO to get more frequency. Set your tRAS to tRCD+tRTP and it will yield zero negative effects to your latency or speeds. G. 45v. Skill Ripjaws S5 for Intel G. 4v 300. $30 for a good bump in performance is well worth it imo. My case cools pretty well… The cheapest DDR5 sticks are not much more then DDR4 and still perform slightly better in many tasks. It's recommended to go off addition of tRTP because it can go lower than tWR. Dec 6, 2021 · Sometimes a fourth primary timing will be listed, if so that is your tRAS or the Row Active Time. 35V (modified primary timings, passed OCCT DDR5 high bandwith benefits 1440p and 4k gaming due to large data transfers, in other words, non-competitive gaming. The only thing I can think of is the motherboard holding back the frequency. Title+ debating on buying a matching 8gb stick with what I got with no heat sink or to buy 2x8gb sticks with heat sinks.
