AMD Ryzen 7-1800X Cracks 5.20 GHz OC with LN2 and All Eight Cores Enabled
AMD's upcoming Ryzen series processors promise to be an overclocker's treat. A PC enthusiast with access to a Ryzen 7-1800X sample managed to achieve an extreme overclock of 5.20 GHz with liquid-nitrogen cooling, and more importantly, not having to disable any cores to stabilize the OC. The 5201.07 MHz overclock, achieved by cranking the base-clock up to 137.78 MHz, and the multiplier up to 37.75X, backed by a core voltage of 1.875V, was even tested to be bench-stable, scoring 2,363 points in Cinebench R15. This also reveals that you should be able to finely crank up the base-clock multiplier in steps of 0.25X, (as opposed to 0.5X). The Ryzen 7-1800X will be available on the 2nd of March, 2017, priced at $499.

5.2Ghz on LN2 is actually, low if you ask me.Are you serious? The OC is done by mixing both higher multiplier and a base-clock. It's since the 286 that whenever you increase the FSB (Base clock) the complete system becomes faster. A system with a higher FSB and lower CPU clock compared to a system with default FSB and higher CPU clock is generally faster.
This is just oc basics and you deny that the Ryzen can be actually faster when properly overclocked.
According to AMD the Ryzen 7 1800X scored 1,601 points in Cinebench. And if said claims of this article are genuine, then a 1800X clocked at 5.2GHz would score ~2,363 points.
[INDENT]5.2GHz/4GHz=1.3
1,601 * 1.3 = 2,081
2,081 vs 2,363 → +13.5% clock for clock efficiency?
[/INDENT]
If the 1800X was making use of XFR on AMD's bench (we don't know) then this would be even more impressive. And even if the 1800X was running at its base clock of 3.6GHz, it would be 2,313 vs 2,363 points (still +2.2% → pretty much linear scaling). My guess is that RAM clocks and timing are probably heavily influencing the outcome, but nontheless those results are very impressive.
Are you equally frustrated by the fact that your new car no longer has an 8-track player as well?
1) New instruction sets are called progress.
2) No-one bothers implementing them in software that is two versions out of date.
3) MS has never released an update that randomly starts bluescreening stuff, at least not by design as you seem to infer. Also, bluescreens are usually caused by drivers or software causing system instability, not the actual OS itself. This would be found out, and lead to a major class action lawsuit. Very, VERY large businesses depend on Windows being stable. Which it is, and as an Wintel/VMware SE for a company with 144.000 employees, I'm pretty sure I have a better grasp of what has gone wrong with Windows OS's in the last few years.
Stop spreading FUD. Seriously, the whining about MS for something you have so little grasp on you might as well be a baboon in a nuclear power plant grows tiresome.
You want MS to backport brand new extensions from 2016 into their software they released in 2009 and gave it's last major overhaul in 2011, even though not doing it will change NOTHING about your experience in Windows 7 on Kaby/Ryzen.
Are you starting to hear how inanely stupid that sounds? You don't expect this kind of service from ANY software vendor you use, yet MS is somehow a demon for wanting to concentrate on newer things instead of infinitely supporting out-dated software.
There are a lot of things you can fault MS on, this is not one of them.

47% is still using Windows 7. It's fairly stupid to start ignoring those 47% of users who still like the looks, feel and simplicity w7 has to offer. Sorry but there's no W10 coming in from now on, where MS decides which updates to install, resets user preferences, messes up updates or even causes dataloss after an migrate from either W7 or W8.
W10 has nothing serious to offer compared to W7. Do you really need DX12 at this moment? Do you really need the tiles and all in your fancy start menu? Do you need the app store to get your favorite program to work? W7 suits me perfectly for what it does.
And I bet your stepmother's printer still works with generic PS drivers.
As I said, it's scary to see 5.2ghz on ln2 considering we are boosting to 4ghz. That doesn't bode well for air or water cooling. I'm thinking we are topping out below 4.5ghz on water...likely closer to 4ghz on air. Remeber, the 6900k starts at 3.2ghz.. 400 mhz below ryzen. ;)
Feels like they have pushed these things pretty far as is.
AMD's done a fantastic job if you ask me.
All in all, it's very very possible that at least some retail chips will achieve even 5.0 GHz on high-end custom liquid cooling systems, and then hit a brick wall beyond which it won't move an inch, and you need LN2 to reach beyond...
What I'm curious about is how turbo and XFR behaves with overclocking... do they need to be disabled? Or, would it be possible to have an overclocked system at 4.5GHz with turbo up to 4.8 and XFR up to 5.0?
Also, this is the second LN2 I have seen. The first was at 5.1GHz. ;)
Turbo, AFAIK, boosts 2c/4t 200 MHz (3.6 to 3.8GHz), XFR takes a single core to 4.1Ghz. I would imagine this should be disabled when you want all cores at the same speed. Otherwise, it can likely be left enabled.Yeah, for those that don't overclock, that is good, no doubt. But for those enthusiasts that overclocks, you then wonder what a 5Ghz 7700K looks like against a 4.2Ghz Ryzen...
dat price tho......
47% is still using W7. There is absolutely nothing wrong with that. I never claimed there was, I can understand the reasoning for it in a lot of cases. We still use Windows Server 2003 for some legacy software applications. But guess what, we also don't expect MS to back-port Hyper-V in those machines, or give us an x64 upgrade path. We don't expect them to give us Office 2010 on Office 365. You know why? Because that we be really freaking stupid ideas to put forth.
You put forth your reasons for not wanting to upgrade to W10, which are mostly based on FUD itself, but that is your choice. MS granting lay users less choice in update matters honestly is a very understandable choice, which you'd understand if you ever have had to support end-user systems. I don't give our users, even our first and second-line support, a single drop of lee-way in their selection of updates. Resets of user preferences after updates have happened in every previous version of Windows I've used since 95, so have messed up updates and data loss caused by a migration, so why single out W10 for things that have been issues since time immemorial, especially pre-SP1?
I'm in no way claiming that W10 is some sort of major revolution. The use of DX12 will show its use in time. I don't use the tiles, but they are perfectly disable-able, which is what I did. Just like I disabled the interface in W7 because I preferred the classic XP interface. The app store changes NOTHING about the fact that you can install any software you wish. If this disturbs you, using a smartphone or tablet must be hell on earth for you.
Also, if W10 offers absolutely nothing over 7, why are you demanding that MS back-port stuff? I have completely lost the logic in any of these arguments.
Intel has this 'issue' too with 7700K. It starts at 4.2, boosts to 4.5Ghz and poops out around 5Ghz depending on cooling and the sample. But, 5Ghz can be done on water. I don't see that happening at all with Ryzen. Yes, its a 8t processor vs 16. The 6900K started out 400 Mhz less (3.2Ghz), can reach 4Ghz+ on ambient cooling, and craps out in the early 5Ghz range too.
Feel like I've said this before.......lol
Back in the 90's when ram was expensive and systems were planned around how much RAM a system could have to determine performance, printers had their own RAM, it made printers expensive, and the drivers only had to tell the system how many KB of buffer the printer had so printer spooling could keep the buffer full, but not dump all the system resources out to make room for simple print jobs. Fast forward 10 years and RAM is relatively cheap, so printer drivers started using system memory and printers became cheap as they didn't have much if any of their own memory beyond the ROM/EPROM of the control chip. This allowed a lot of exploits on operating systems as you could easily overflow the printer buffer with little or no checks on where or who the print job came from ( I did it for fun, and actually reported the issue when I was in the beta program for Vista). MS essentially made the choice to try and patch around it as there were a LOT of users with cheap printers that would have no usable printer moving from Windows 98/ME-XP to Vista and the security hole remained.
Fast forward to Windows 10 and many of the holes have been patched and manufacturers have been forced to update their drivers (it really is their responsibility to keep their hardware up to date, and prevent memory leaks, and security holes) to a model where the driver must pass certain requirements for its own memory management, and other security checks to prevent security breaches and holes.
In short, the printer probably doesn't work as it has a shit driver and MS is tired of taking the blame for cheap printers causing issues.
I've tried to talk him out of it. We shall see if he sends it to me to save his sick and twisted soul.
