Every AMD Ryzen CPU will have an unlocked multiplier

AMD has confirmed with some slide releases that the next-generation CPUs it will be releasing as part of its Ryzen range, will have fully unlocked multipliers. That's not a restriction to high-end chips either: every single Ryzen CPU will be ‘unlocked,' meaning every chip can be overclocked very easily.

While once upon a time overclocking was a lucky extra that some CPUs were more capable of than others, somewhere along the way Intel decided it could use overclocking ability as a selling point, so it only unlocked the multiplier on some of its chips. That's not a tactic AMD plans to use with its Ryzen chips though.

Of course you will still need a decent motherboard with the right features (x370, x300 and B350 chipsets only) and enough stability to make it work – as with any overclock – but you won't need a specialist CPU. You also don't need fancy memory either, as one of the advantages of multiplier overclocking is that it affects the CPU only.

Ryzen owners may not even need to do any overclocking themselves, as AMD's Extended Frequency Range could see chips automatically overclocked to their full potential when needed.

Also detailed in Infoworld's break down of the new chips, was that if you are looking to run crossfire or SLI setups on a Ryzen platform, you will need an X370 motherboard. The other chipsets will not support it. According to AMD, that's because only those who buy top end motherboards tend to use multi-GPU set ups anyway, so adding support for that to entry level models wasn't seen as a necessity.

KitGuru Says: It's good to see AMD not putting limiters on the performance potential for its chips and forcing people to pay for the privilege of overclocking. Just make sure you get a compatible motherboard if you're looking to get into it yourself.

The launch of the new Intel Core Ultra 200S family of CPUs along with Z890 motherboards was a thorny process. KitGuru suffered along with pretty much every other review site on the planet and you may have noticed we held off from reviewing of the Core Ultra 9 285K, Core Ultra 7 265K and Core Ultra 5 245K as it is clear to us that Intel has some work to do before this platform is ready for action.

  1. “multiplayer”, really?

    Davor, Multiplier does not mean multiplayer

    For all your multiplayer needs

  4. Good to know about the Multiplier being fully unlocked as I am hoping to get one of these CPU’s if the performance pans out the way everyone is hoping for. I am sure that most likely it is because of the way the chips are designed that the multi is fully unlocked this time around. We may find that in a future revision of these chips down the road that they will start with the black edition CPU’s once more. I guess it could be just a marketing ploy as well to get people to switch over to their new Ryzen CPU’s and it is a good one at that because overclockers do like to squeeze the most out of their hardware and if restrictions are for the most part removed it does get their attention for sure.

  5. But how is the singleplayer experience?

  6. Meh, why overclock cpu’s anymore? Is that 1 frame per second gain going to really be worth all the risk? Be careful with this stuff people if you are new to it! Very small steps each time, with lots of testing time.

    Ho ho ho…. AMD needs to have unlocked parts, because at stock they are so lame compared to intel i5 chips and won’t be that cheap either! *runs before the poop starts getting flung around*

  7. I’m more excited about AMD’s extended frequency range, I don’t really want to OC my CPU, but well and truly happy for it to clock itself as high as it wants, when it wants.

  8. After resigning my desk job 12 months ago, I was blessed to learn about following job offer which was a life changer for me… They hire people to freelance from home. Last paycheck after being on this job for them for four months was 10000 bucks… Amazing thing about it was that the only thing required is simple typing and access to internet… FL-Y.COM/3m09

  9. It’s brilliant that amd are doing this Amd chips have always overclock far better than intels that still heat up an awful lot and that’s what holds Intel cpus back. It’s not a lot to do with cooling it’s down to the way the architecture is designed not as heat disapating as it could be that’s why they are tweeking skylake and renaming as kabylake. In fact it’s very little improvement. Amd chips can go very very high especially amd s apus they overclock so well better than the fx which is bit older in design. With the lower tcp in ryzen I think we will see world records smashed this year with overclocks of way over 8.00 ghz. Think a new record will be a lot higher. Intel are boasting kaby lake at 5.00 ghz is so way off amd have achieved that three years ago I’ve had my 6800k at 5.00 ghz on air! For over three years stable no crashes day in day out you can get 5.00 on and Intel i7 but your thermal limit is very very close slightest over pushing in apps and multi threaded programs and it crashes out. That doesn’t happen with Amd chips if your set up is good

  10. 1 frame a second/ I guess overclocking isn’t your strong point.

  11. Unfortunately the XFR is only extendable to +100 mhz. Unless I missed something from their event, that’s how I understand it.

  12. Yeah, which seems absolutely pointless and counter intuitive. Although holy thread necro man.
