Not lengthy after our Constructing 3x Intel Xeon W-3400 Workstation and Servers with the ASUS Professional WS W790E SAGE SE article and video, an organization referred to as V-Colour reached out to us about their reminiscence equipment. We had a Kingston Fury Renegade Professional 16GB DDR5-6000 ECC RDIMM that we used as an improve to plain DDR5-4800 ECC reminiscence. V-Colour went greater with twice the capability and sooner speeds. That V-Colour DDR5-6400 equipment is the topic of our mini-review at this time.
V-Colour 256GB 8x 32GB DDR5-6400 RDIMM Equipment Overview
Looking on the DIMM, we get the label displaying this can be a TR532G64D832SO equipment that’s DDR5-6400 / PC5-51200 CL32 at 1.4V.
The RDIMMs got here outfitted with warmth spreaders that have been chrome in shade.
We will additionally see that that is DDR5 ECC RDIMM reminiscence. Not like with DDR4, one can not use shopper unbuffered reminiscence in DDR5 RDIMM slots, which makes kits like these extra attention-grabbing than in earlier generations.
One thing that we appreciated was that these clips and warmth spreaders truly made it a lot simpler on the fingers to put in the modules. Anybody who has put in dozens of DDR5 modules in a day has in all probability skilled fragile fingers. I didn’t imagine that was a factor till putting in 24 DDR5 DIMMs in an AMD EPYC Genoa server. Having these warmth spreaders helped.
The equipment arrived in two 4x 32GB DDR5-6400 kits. One of many largest challenges with fashionable workstation CPUs is that when we’ve got 56 cores, an 8x 16GB DIMM equipment is simply 128GB for simply over 2GB/ core or 1.1GB/ thread.
This equipment was put in in our ASUS Professional WS W790E SAGE SE Intel Xeon W-3400 motherboard in addition to within the Falcon Northwest RAK utilizing the identical motherboard. We lined these builds in Constructing 3x Intel Xeon W-3400 Workstation and Servers with the ASUS Professional WS W790E SAGE SE.
We will even have the FNW RAK system overview quickly on STH. It simply occurred to be probably the most photogenic for photos given the liquid cooling block quite than air cooling.
All instructed, with 8x 32GB RDIMMs we had 256GB of reminiscence giving us simply over 4GB of RAM per core, which is a good determine.
This equipment, on the time of scripting this overview, was not on the QVL listing for reminiscence modules on this motherboard, however V-Colour has 16GB RDIMM-based DDR5-6400 kits on the listing in addition to 32GB RDIMMs at DDR5-6000. Different QVL distributors are Kingston and G.Ability. It was spectacular that V-Colour was on the listing for such a high-end platform.
The large query was, would they work, and on the rated speeds?
V-Colour 256GB 8x 32GB DDR5-6400 RDIMM Equipment Efficiency Instance
Fortunately the set up was tremendous easy. We may simply use the XMP profile and the DDR5 equipment labored at DDR5-6400 out of the field.
Only for some sense, we had executed an AIDA64 run on what can be our “normal” 512GB configuration utilizing 8x 64GB SK hynix DDR5-4800 RDIMMs that we purchase for servers.
Placing the brand new reminiscence modules in halved our capability, however we have been a bit shocked at how way more bandwidth they offered. It was not the theoretical 33% improve, but it surely was very noticeable.
The 8x 16GB Kingston DDR5 reminiscence went again with the Falcon Northwest RAK, however we had taken a screenshot utilizing AIDA64 earlier than it did.
Even with the overclock from Falcon Northwest, the V-Colour remains to be out-performing the Kingston reminiscence equipment at twice the capability.
Remaining Phrases
The V-Colour DDR5-6400 256GB RDIMM equipment was tremendous simple to make use of simply relying upon a XMP profile setting to get enormously elevated reminiscence bandwidth. Allow us to take a second and take a fast observe on the massive draw back: value. The 8x 32GB DDR5-6000 equipment is listed at $2,399 on the V-Colour website. The equipment we’ve got will not be listed but, however the 16GB kits see a roughly 10% listing value improve from DDR5-6000 to DDR5-6400. At $300/ 32GB, that’s costly reminiscence. To offer some sense, we’re spending about $100 for traditional server DDR5-4800 32GB ECC RDIMMs today and about $200 for DDR5-4800 64GB RDIMMs. The pace binning and testing is actually price a premium, particularly for many who have reminiscence bandwidth-bound purposes. On the similar time, having a 3x value premium looks as if quite a bit. Maybe the largest competitors is not only Kingston and G.Ability, but additionally the idea of getting twice the slower reminiscence (512GB) for 33% much less price.
On the one hand, that is tremendous cool. The intel Xeon W-3400 collection can go from DDR5-4800 to DDR5-6400 steady utilizing this V-Colour reminiscence and deciding on the XMP profile. That’s precisely the habits we might need. However, there’s a steep premium for pace.
Nonetheless, it appears like Intel’s Xeon W-3400/ W-2400 messaging misses the truth that its reminiscence controllers can assist these sorts of speeds. In case you do want higher-speed reminiscence and likewise need capability, this equipment is superior.
