AMD processors ca n’t make full use of CUDIMM memory just yet , but it may well do before the end of this socket . In a recent interview with DigitalTrends , AMD ’s product management trail for play and workstations , Sourabh Dhir , told us that there was no reason that AM5 could n’t support CUDIMM , but would n’t be draw on a timeline of when we might see it .
moot we look AM5 to be AMD ’s flagship mainframe socket for the next couple of generations at least , that probably mean we do n’t have long to wait for the added memory speed support .
What is CUDIMM?
CUDIMM is thelatest memoryDIMM banner that adds an onboard clock tuner to the memory faculty themselves . It ’s an evolution of DDR5 ’s original advance in power direction , incorporating that onto the sticks themselves . What CUDIMM does , is append a chip that boosts the clock signal from the CPU ’s computer memory controller , delivering a clean-cut signal for the store . That leads to greater stability , and finally , mellow memory frequency .
It ’s think of that companies like G - Skill have launched memory with rated speeds as high as 9,600 MT / s , and often they can be overclocked to over 10,000 MT / s on breeze , or even over 12,000 MT / s when more exotic temperature reduction is involved .
The only problem for AMD is , its CPUs do n’t currently endure it . Or at least , the onboard clock tuner which allows for such advanced oftenness . presently , if you secure a stick of CUDIMM into an AMD motherboard , even a high - end , latest contemporaries X870E board , it ’ll run in what ’s known as “ beltway fashion , ” and will only function at the highest speeding the motherboard support — not the rated swiftness on the module .

Intel ’s modish Core Ultra 200 Arrow Lake processors , however , can fully bear out it , leave AMD somewhat languishing on memory velocity , even if it is n’t some plot change performance ash grey bullet train .
When will AMD get CUDIMM support?
Not yet , but probably not far into the future , either . In our chat with Mr Dhir , he was decipherable that AM5 was more than capable of supporting CUDIMM ’s features and afterward , its frequencies .
“ So as as our storage route map is develop , you ’ll notice that unlike different innovations are result to unlike form agent on the DIMMS . CUDIMM is a engineering which allows our DDR5 speeds to go beyond 6000 speeding , and I do n’t retrieve we we need a new infrastructure to support these . ”
When urge on on whether this was something that could be enable in a BIOS update , or if it would need a Modern chipset and mainframe generation ( even if not a newfangled socket ) , here just confirmed :

“ Within the same AM5 substructure , ” he elucidate . “ It ’s robust enough . It ’s future proof enough , and it ’s built for for supporting these [ ontogeny ] . ”
His final send off on the topic suggested this might not be the last we find out of either CUDIMM support , or additional DDR5 capabilities and feature article beyond it .
“ Anything you discombobulate DDR5 at it , [ AM5 is ] build to suffer these capabilities . ”
Arrow Lake is the only platform that supports CUDIMM for now.Intel
Before AM6
Elsewhere in our confabulation , Dhir suggested that the major motivation for AMD change sockets was toimprove store supportand capability .
“ When DDR5 came into market , we want to sweep up that engineering early , ” he said . “ We wanted to give the benefits of that , ameliorate bandwidth , improved memory capabilities . ”
He went on to propose that DDR6 may well be the driving component of AMD moving on to an AM6 or other future socket design in the time to come , though would n’t be drawn on specifics . This would very much intimate that we ’re going to see CUDIMM support this side of go to DDR6 and AM6 , but with no clear roadmap as to when beyond that far future tense “ before ” date .
Offering another small nugget of promise in this conversation was AMD Porto Rico manager , Matthew Hurwitz , who spent sentence work at Gigabyte in the past tense . While he was decipherable to state that he was n’t speaking for his old employer , he did want to emphasise the inter - generation improvements of AMD chipsets , and how even when using the same socket , memory improvements were common .
CUDIMM for AMD is n’t here just yet , but it feels that bit closer to me , after this New World chat .
