CCX Overclocking Tool for AMD CPUs Updated With New Features
Today an overclocking utility for AMD Ryzen CPUs called "Work Tool" has been updated with new features. The tool enables per-CCX overclocking, which is said to enable additional overclocking performance if one CCX is more capable than the other, so the whole CPU doesn't have to run at the speed of a slower CCX to be stable. The tool has been released by user shamino1978 on Overclock.net forums.
The reason for overclocking Ryzen CPUs on per CCX basis is because if you want to overclock a single core inside a CCX, the second core must run at a 1 GHz difference, meaning that if one core is OC'd to 4.5 GHz, the second core must run at 3.5 GHz. Such design is to be blamed on CPU's internal clock divider. However, you can use the Work Tool to do individual CCX overclocking and gain additional performance. Additionally, the tool has been updated to support tweaking of voltage aka VID. There are two versions of the tool, one which is smaller and has less features and one which can tweak the voltages. The smaller version is available here, while the bigger, more capable version is available here.

with xfr and pbo nobody needs to now, just add cooling and the chip will give you all it's got.
why are people shocked to hear an top tier clocker uses/creates tools that push performance at the cost of longevity?
they don't pay for their hardware, they get paid for results that highlight the bleeding edge performance not 24/7 mission critical stability.
i have lots of respect for what shimano has done over the years, he is a god tier clocker. much the same as i have for 1usmus. but for totally different reasons.
AMD set our expectations too high with their marketing. Which might bite them in the ass when the fried CPUs from the CCX OC tool get back via RMA.
Adoredtv pointed out some interesting thoughts on why AMD consumer CPUs are so "bad"
To make it short, AMD saves the best chiplets for the Epic server cpus. So we just get the chiplets with the poorer quality. With the 4000 series we might get the higher quality chiplets which have higher clocks.
I think he is right on that one, and i even can't blame AMD to get as much money out of Ryzen 3000 as they can. They even made their 2000 series absolete and are a competition for their Threadripper series. And i personally think that PCI-E 4 will stay on the pre X570 boards. AMD fought against the Unlocking of Phenom II as well, but just gave up.Here is the link to the CCX OC Video
As for CCX oc`ing: most apps or games do not utilitize all 16 threads on a regular ryzen CPU. Many games such as Pubg and so just allocate 4 threads. It makes sense to aim for CCX only overclocking where 4 out of 8 or even 12 / 16 cores are clocked highest, and with a software tool automaticly assign the most using threads to the fastest cores. This way you could still archieve some profit here and there, but the effort from old school bios adjustments, reboot, testing, adjustments and retesting has now shifted to basicly software tweaking.
Pinocchio's nose keeps growing.
Overclocking isn't for everyone.
What is more concerning however is that someone registers on a forum and first thing they post is throw blame of something or someone else, without providing any kind of evidence of their claim, or explaining anything about what they tried to do.
That is instant-ringing-of-troll-alarm-bells.Oh wow, wth happened to that video ?
It was named "AMDone", and he ended by "I'll stop believing anything that AMD marketing says, they lie through their teeth"
He was quite harsh on the launch of this generation, on how AMD "adjusted" their slides and presentations to mean something else than initially...
My understanding is that he tried to explain why his previous "predictions" fell short by A LOT, and the fact that it's very difficult to explain why 3000 series aren't clocking as high as they -should- on 7nm, and the conclusion is:
The entire Ryzen 3000 series is "garbage chips" with high leakage that are rejected for EPYC use, which they sell to consumers because even as bad as they are, they are still better than what Intel offers in most metrics.
Such claim might also explain why these "garbage chips" run so hot out of the box, and why they need massive voltage spikes in PB ( up to 1.5 ) to clock to their specs, 4400-4600 mhz, which not only is not much higher than previous gen, but also much lower than what should be possible on 7nm.
Selling "trash" as the latest and greatest....
Hmm... I wonder why the video was removed?
(Well I bought one of these trash chips, because it's less trash than the Intel trash I had before)
The just registered guy says that he has access to "many... RAMs and motherboards. PLURAL., but he doesn't have access to a bloody camera ?
When every lousy phone starting with $100 has a camera good enough for an art exposition ?
I really don't understand why are you trying to defend an obvious troll.
"Let's register on this forum and dump some unsubstantiated bull$hit about something !"
Anyway, I'm done here.
