[@noreng9333]

When it comes to IOLs and RTLs, the way to tighten them is to use the IOL Offset value. The way IOL Offset and IOL work together is that when your motherboard is training correctly, the sum of IOL and IOL Offset equals 28 or 27 (i.e. 7 for IOL and 21 for IOL Offset). If the sum over IOL and IOL Offset is some large value like 32 or 35, you need to lower IOL Offset until the sum of IOL and IOL Offset starts to add up to 28 again. This can improve your DRAM latency (as measured by AIDA64) by a couple of nanoseconds. Lower IOL Offset can also help you boot higher memory speeds as it helps the memory controller time well. Conversely, if your motherboard is training good IOL values, increasing the IOL Offset can actually make your motherboard train tighter RTLs and IOLs, this is how those Z490 Apex running 4600+ MHz with IOLs at 4/4 are reached.

I've done gaming benchmarks with manually overclocked SR vs. DR B-Dies a while back. TL;DR: A 4133 DR overclock is slightly superior in most games to a 4500 SR overclock. Exceptions were some very old titles, that simply don't need the additional throughput, so they prefer the lower latency SR overclock. This was back with Z390, when there was like 1 specific Gene BIOS (I think 0602) that could actually work well with 16 Gig B-Die DIMMs. In the German Hardwareluxx forum there has been a lot of testing and discussion about this topic as well and the conclusion appears to consistently favor DR. Especially when you consider that now with the Z490 Apex, you can run DR DIMMs at 4500 and in some very lucky cases 4600 with tight subs and everything. On Ryzen 3000, this would be the easiest discussion ever. For actual daily performance, both are limited to 3800 anyway, so SR doesn't even get the benefits of having higher clocks anymore.

8:20 I believe a basic LSB radix sort on a very large array of random integers would be a very latency-dependent workload, if you need one. You're accessing large sections of RAM basically randomly at first, but copying very small amounts of data each time. Essentially no computation involved, just loading small amounts of data and copying them around.

[@MrDrago1954]

Buildzoid, I know your time is valuable, so you make the call. Would it be worth your time and your viewers to give an explanation of ALL the ram timings available on a motherboard and the ranked impact of each one on overall performance? I seem to remember not too many years ago a chart I used for manual ram timings that had like two dozen ram timing adjustments. Are all those adjustments still offered thru the Bios on current Mobos? Anyway, maybe someday when you have more time.

[@mattiasolsson3557]

The added latency from 4 dimms might be entirely motherboard dependent. I run 4000C17 g.skill dimms on my WS Z390 Pro and I get very similar results in the 38-40ns range with 2 and 4 dimms at 4300@C18 in AIDA. Is the MSI you used daisy chain? Have we perhaps stumbled upon some advantage of having t-top?

For the oversimplification sake, four SR dimms in dual channel is similar to the SMT or HT technology, for the memory controller. This is relevant today, with the fastest ddr4, because of the number of clocks between operations, it's so big, there's room for other memory operations... Four DR in dual channel induces too much latency, is not beneficial. There's that, I've saved you some time.

I know this is probably answered in this or another of these videos (since AHOC explains literally everything), but maybe someone knowledgable can throw me the answer really quick: *Does the CR (1T/2T) and the tRC matter?* I notice AHOC has 2T for all modules while mine shows 1T (and 75 clocks for tRC) (3200 14-14-14-34 SR).

[@malphadour]

Most XMP profiles seem to default to CMT 2 - most also default to Gear Down Mode enabled(where the CL number is even) - this is a safer default as some older topology boards can struggle with 1T timings. Setting CMT to 1 can help performance as long as it runs stable. Tightening up tRC will have decent positive impact as well as this is a fairly important timing. Your can also get large gains with trrds,trrdl and tFAW which you tend to tighten up as a group. At the end of the day, you can spend, hours or days mucking about with your timings and they all help. The question is whether those gains translate into any meaningful performance gains rather than just improving benchmark scores. This is entirely dependent on what you use your PC for.

Hi Buildzoid, do you know if there are any single rank 16GB sticks on the market? Or are all 16GB sticks dual rank.

[@ActuallyHardcoreOverclocking]

yes there are. Curcial makes some 16GB stick 16Gb revB kits. My 4000 CL18 2x16GB Ballistix max is one of them: kzbin.info/www/bejne/pZKxo35-h6aZptk and: kzbin.info/www/bejne/qnW0nZmDabBliJY

Bro wouldn't you just use 32M pi to isolate latency?

[@Fin4L6are]

what about quad rank?

[@severgun]

Can someone give me timing of conclusion?

[@eugkra33]

Was this tested with 1 stick or two sticks? It's single rank and dual rank total, or on each stick? If it's only 1 stick, how would doing this in dual channel impact these numbers if at all?

I believe he uses 2 sticks for SR and 4 sticks for DR.
