If I do so I definitely would be willing to push the voltage farther but right now even at 1. 40V F5-7200J3445G16GX2-TZ5RS As you reach the upper end of current ddr5 available on the market, your chance of getting Hynix M increases as it’s more suited to high frequency and needed to guarantee faster XMP profiles. Hard to tell where regular usage ddr5 will cap out at (basically the ddr5 equivalent of ddr4 3200/3600). This is probably the most consolidated and comprehensive information on AM5 DDR5 I've seen. for faster response and lower input lag. 55ns to 45ns is where you start tightening Not sure what you mean by this. In addition, subtimings have a significant impact on performance. For example, . 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. Skill's camp. Tested to be stable at up to 65 o C SPD temperature. Now DDR5 has either "normal" ECC sticks, equal to one of last generations, or one can buy much cheaper on-die ECC sticks. 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. $30 for a good bump in performance is well worth it imo. Nov 5, 2022 · Here is how I got my Hynix A-Die DDR5 stable at 6400MHz with the below timings.

Too low tRAS will just increase instability, and the Hynix 3GB M-Die generally doesn't like too low tRAS/tRC. Learn to overclock, ask experienced users… I'm gonna describe the operation of DDR5 to the best of my knowledge. To pass initially I was at 1. 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. They reduce latency and often increase effective bandwidth by reducing bubbles of bandwidth loss, even though the ceiling doesn't go up. 70 votes, 33 comments. Does it really matter though ? For Hynix M/A-Die, tRAS can usually be floored to 28 without any issues. etc. 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. Then tRC should equal tRAS+tRP so 50+38=88. DDR4 low timings (ex. 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. i can give you the best settings for that board. Skill have shown off DDR5-7000 CL40 running stable on some of the higher end Z690 boards.

Other than timings, you could try raising MEM VDDQ and CPU VDDIO to get more frequency. I know DDR5 is in its infancy and all that… However, I am curious who is showing more potential this DDR5 season. It would then become something like CL36-38-38-52. But yes, you can buy cheaper DDR5-4800 today, and drop in DDR5-7200+ in the future. 4 the stick closest to my CPU I'm looking to buy some DDR5 RAM (16GBx2) for my new build and I've been looking at G. 45v. tREFI is the biggest single gain you can have but it makes the memory extra prone to corruption if it is too hot. 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. 288K subscribers in the overclocking community. 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. 45V, we only reduced the tRCD, tRP, and tRAS from 39 I am planning to build an 48TB Raid Z2 Nas on Ryzen 7000 with DDR5 RAM. Once DDR5 comes way down in price I'll get faster RAM then. 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. All Hynix can do 40-40-40-77-117 + tRFC 840 / tRFC2 640 / tWR 96 @ 6400 1. It's overloading the CPU and controller by forcing more information than it can handle. 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. 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. My point is that currently (and likely for another year at least) DDR4 is faster than DDR5. It doesnt get that much cheaper when buying 5600 and it does get a lot more expensive when buying anything over 6000. You will also gain enough stability to *maybe* be able to run tCL30 instead of 32. 3. Lower tRAS likely won't have any impact. I have the same board and RAM (A-Die as well) as you, and I cannot run anything stable higher than DDR5 6600. And that's measured in ns so it's taking into account speed and timings. First, load a memory profile for say 6200 from your motherboard. I'm looking to buy a DDR5 kit and I hesitate between Corsair and G.

When it comes to DDR5 especially, my suggestion is to buy something listed by your mobo maker's QVL (qualified vendors list). 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. 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. Technically speaking I can tighten tRAS/tRC up to 46/84 and tREFI to 65535 but that will make it unstable at ~58 o C and it won't net any measurable performance improvement. what is the best bang for your buck DDR5 speed these days? G. The goal of tightening timings is to decrease the latency. Leave the rest of the values on auto. 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. I believe the way the primaries work means you would want tRAS to be tRP+tRTP so 38+12=50. 46v. 4 GB/s per channel and a single access 32GB of DDR4 3600 CL16 is around $95. But thats for central Europe, could be different elsewhere. I just ordered a G. G. Recently built a 14900K system with 48GB DDR5-8000MT/s RAM. Either way, I'm going DDR5 with this, hence my question.
