G.Skill's new DDR5-9600 CUDIMM sticks can achieve DDR5-10000 speeds on air cooling

zohaibahd · Friday at 11:11 AM

What just happened? G.Skill just unleashed its Trident Z5 CK and Trident Z5 CK RGB DDR5 RAM designed specifically for Intel's freshly launched Core Ultra 200 processors and Z890 chipset motherboards. The headliner is that these sleek memory sticks are rated for a blistering DDR5-9600 straight out of the box.

To achieve such speeds, G.Skill has employed cutting-edge CUDIMM technology that integrates a clockdriver chip onto the RAM modules themselves. This helps stabilize the signal between the memory ICs and the CPU for more reliable operation at extreme transfer rates.

The company says that no adjustments in the BIOS are required to enable the overclocking profiles – all you have to do is drop the sticks into a compatible Z890 motherboard.

For those looking to push things even further, G.Skill will offer a premium 48GB CU-DIMM kit (2x24GB) clocked at DDR5-9000 with CL42-56-56-144 timings. The company claims to have hit DDR5-10000 speeds in their labs with these modules, using air cooling and flagship Z890 boards from Asus and ASRock.

Beyond offering such blistering speeds, the new Trident Z5 CK line maintains that signature G.Skill look with a sleek black brushed aluminum heatspreader and matching black top bar. Alternatively, you can opt for the RGB versions, which swap that bar out for a translucent lightstrip.

There are a couple caveats, though. First, you'll need cutting-edge Z890 hardware to unleash the full DDR5-9600 potential, as Intel's Core Ultra 200 CPUs alone only support up to DDR5-6400 speeds with CUDIMM or DDR5-5600 with standard DIMMs when running stock settings.

Second, these CUDIMM kits are currently Intel-exclusive since there's no support for AMD EXPO (Extended Profiles for Overclocking) yet, meaning you'll not be able to pair them up with the latest Ryzen 9000 CPUs.

However, if you're going for an ultra-enthusiast platform built on Team Blue's latest, these new sticks could allow you to pair that up with the fastest RAM clock speeds in the industry. The Trident Z5 CK and Trident Z5 CK RGB series DDR5-9600 memory kits are currently listed on Newegg.com.

I think I'd get more from an overpriced custom water loop than these high latency dimms. I know it's enthusiast level, but I still don't get it.

You'll probably have to remortgage your house, or sell your car, to buy 64Gb of these along with a suitable motherboard.

It over 9000 !!11111
realy ? it look useless, so far benchmark showed this processor dosen't scale performance with faster RAM

These aren't high-latency. CAS latency for modern synchronous DRAM is specified in terms of clock cycles, so CAS latency figures alone do not tell you how responsive it is. You need to take the clock rate into account as well. DDR stands for Double Data Rate, meaning that data is transferred on both the rising and falling edges of the clock cycles. So the clock rate (in MHz) is half the transfer rate (in MT/s).

CL42 at 9000 MT/s (4500 MHz) is 9 nanoseconds (42 / 4,500,000,000). An example comparison would be to a Corsair Vengeance kit (CMK64GX5M2B6400C32), running CL32 at 6400 MT/s (3200 MHz). That's 10 nanoseconds (32 / 3,200,000,000) -- slower than this G.Skill kit.

In fact, 9 nanoseconds is some of the fastest DDR5 currently on the market.

Once you pass CL 38 it's high af imo.
Def not for gaming. Productivity maybe.

Except, again, as I explained, you can't just look at the CAS latency figures alone and conclude whether it's high or low. You need to take into account the clock rate as well, because CAS latency is specified in terms of number of clock cycles, not an amount of time.

CL42 at 6400 MT/s is a 31% higher latency than CL32 at 6400 MT/s. So yes, this appears to be a high latency.

However, CL42 at 9000 MT/s is a 10% lower latency than CL32 at 6400 MT/s, and you get 41% extra bandwidth as well (9000 MT/s × 64 (memory bus width in bits) ÷ 8 (bits per byte) = 72000 MB/s).

Edit: All percentage figures rounded to nearest whole number.

Lets see some real world benchmarks with these CUMDIMMs. High clockspeed with high latency tends to be irellevant in most cases, especially gaming.

I would much rather see 8000/32 than 10000/48

What have the reviews shown here using higher than 7200 on Intel and 6000 on AMD?
