G.Skill Trident Z5 Memory Overclocked to DDR5-9560 CL120 Using LN2

[Uskompuf]

We recently reported on the DDR5-8888 CL88 Overclocking world record set by G.Skill, ASUS, and overclocker "lupin_no_musume" using G.Skill Trident Z5 DDR5 memory on an ASUS ROG Maximus Z690 APEX motherboard. This same overclocker has now set a new record using the same memory and motherboard combination achieving a speed of 4779.7 MHz (9560 MT/s) at 120-120-120-120-127-2 timings using liquid nitrogen cooling. The record was set with a single 16 GB Trident Z5 DDR5 memory module paired with an Intel Core i9-12900K processor.

I like seeing the 9560 here being referred to as Mbps

1 Bit per Second = 1.5625E-08 Megatransfers per Second
1 Bit per Second = 1E-06 Megabit per Second (SI def.)
∴ 1 Megatransfers per Second = 64 Megabit per Second (SI def.)
∴ 9560 Megatransfers per Second = 611840 Megabit per Second (SI def.)

DDR-9560 Single Channel = 76GBytes/s

∴ 1 Megatransfers per Second = 64 Megabit per Second (SI def.)

This sounds like utter nonse. The conversion rate should be at the very least 1:1 and at best... interface specific.

Bitrate stated in bits per second (Mbps, Gbps) seems to be the most common industry standard used by manufacturers to indicate the data rate "per pin/lane" in memory chips. There are some examples of MT/s being adopted lately instead, but historically megatransfers were often used to indicate the raw bandwidth (including encoding losses, like in older pci-e where 5GT/s gave 4Gbps).

DDR-9560 Single Channel = 71.2GBytes/s

Well... A single channel of DDR5 is 32 bits of data, therefore it would only be 38.2GB/s (as opposed to 76.4 in 64bit scenario). Unfortunately it seems that "Dual channel" meaning four channels is going to be the norm when it comes to DDR5 (and supposedly eight in DDR6 ).

I've updated it to MT/s to clear any confusion.

Holy batman timings! Really? CL120 ?? That's around 25.1ns latency...
An 3600 DDR4 with CL16 has 8.8ns latency, you realize that this whole experiment is completelly useless.

As are most overclocking records.

Wow, so latency. Very money.

Right BoyWonder! My OLOy PC4000 CL 15 is at 7.5ns, which why I downclocked the Bat Computer's memory to PC3600 CL14-14-14-34 giving me 7.8ns!!! It does Bat Wonders on the electric bill.

1 DIMM for a record is kinda lame. No one else does 2x. That's a real challenge.

1 DIMM for a record is kinda lame. No one else does 2x. That's a real challenge.

With the new DDR5 standards, drop in attainable frequency is even more pronounced going from 1 DIMM to 2 DIMMS.
Max. overclocking frequency example:
1DPC 1R Max speed up to 6666+ MHz
1DPC 2R Max speed up to 5600+ MHz
2DPC 1R Max speed up to 4000+ MHz
2DPC 2R Max speed up to 4000+ MHz

So a single DIMM should always attain the a higher frequency than 2 DIMMS.

Maybe they should have a 2 DIMM frequency record as well.
These records are usually just bragging rights has with most LN2 OC records. Running LN2 on your RAM is hardly practical for most people anyway.

 

[bart1969]

Yeni DDR5 standartlarıyla, 1 DIMM'den 2 DIMM'e gidildikçe ulaşılabilir frekanstaki düşüş daha da belirgindir.
Maks. hız aşırtma frekansı örneği:
1DPC 1R 6666+ MHz'e kadar maksimum hız
1DPC 2R 5600+ MHz'e kadar maksimum hız
2DPC 1R 4000+ MHz'e kadar maksimum hız
2DPC 2R 4000+ MHz'e kadar maksimum hız

Dolayısıyla tek bir DIMM her zaman 2 DIMM'den daha yüksek bir frekansa ulaşmalıdır.

Belki de 2 DIMM frekans kaydına sahip olmaları gerekir.
Bu kayıtlar genellikle çoğu LN2 OC kaydının sahip olduğu övünme haklarıdır. LN2'yi RAM'inizde çalıştırmak zaten çoğu insan için pek pratik değil.:kahkaha:

Is this combination issue like "1-2DPC;1-2R" only valid for MSI? I do not see this narrative in the technical information section of any brand product page other than MSI.

If I bought another brand other than MSI, would it not matter how many ram I installed?
