Very new to RAM OC'ing but very interested in learning everything by testing.
I'm running an AMD Ryzen 7 9850X3D on an Asus STRIX X870-F board, combined with a G.Skill F5-6000J3038F16GX2-TZ5NR DDR5 kit. Overall I'm very happy with the performance even tho it was a pre-build system.

In HWInfo64 I noticed the memory running at 3000MHz as well as the UCLK running at 3000MHz. I assume the UCLK is adjusting to run in a 1:1 ratio with the memory.
the FCLK is 'only' running at 2000MHz and ChatGPT is telling me I could reduce the latency between the CPU and RAM if I bump this higher. While it's actually not really OC'ing the RAM but actually the CPU I want to play with this.

How plausible is it that I could make the FCLK run at 3000MHz? So they run at a 1:1:1 ratio? If I try to bump this speed, at what intervals would you all recommend I do this? And how big are the chances that I'm putting too much of a burden on the infinity fabric?

Thanks for reading my stuff :) appreciated!

thanks responses

嗨：
我有一个 Ryzen 9 5900X 和 Windows Server 2019，当我尝试运行 Ryzen Master 时，我收到错误：

Ryzen Master 10 需要让 Windows 运行的
版本
。

谢谢

The strange thing is, that all other BIOS settings seem to apply fine multi, RAM divider and timings get saved propperly (even though the board doesn't reboot after the warning screen)

Things i have tried so far:

2 BIOSes on 2 diffrent chips 1x Infrared BIOS and 1x Manta Rays

Raising the FSB in windows --> got up to 117 then crash

multiple BIOS resets, all diffrent RAM channels one old unlocked and a newer locked barton...

Hope someone with socket A experience can help me...

I have Asus Zenith Extreme Alpha and x399 Aorus Extreme.

For either of this 2 if you have a working stable bios. Many thanks !

Since some time I have 2 Abit AN7 boards. Great boards and I can mod the NB voltage and all...

But the Windows XP installation and stability is a horror. While installing I had to make backups of every reboot in the installation process and to come to that point it costs me at least 10-30 tries. I tried several bios versions (modded or not modded), ATA and SATA drives. nothing help, any idea what the problem is? 
 

Note that I also have a dfi, Abit nf7-s (2) and an Epox board working fine with all hardware. 

If not mistaken , that's the latest version shamino provided.

Anybody has a download link ?

Is there any confirmed and easy way to install XP on nForce 2 board, preferably on SSD? Maybe sort of IDE->SATA adapter. Looks like IDE is the way to go if you don't want to prepare million of CDs with XP installs. USB install doesn't seem to be working good too, I'm not sure if Soltek's board use it, on Chaintech it works.There are also IDE SSD drives on the market, but I'm not going to spend another ~50 euro on such drive only for testing purposes.

Thanks,

Bartek

 I wanted to share this binning result of 7 CPUs. The lucky one makes 10 minutes of memtest at 780 mhz with 2.5V and -96 on the evaporator.  Post at 810 but no memtest.

 Also ask some questions to those with more specific experience:

@Gumanoid told me that his CPUs have CB at around -40 degrees.  What are the numbers of your experience?

I succeed with ACPI Multiprocessor on Ryzen CPU. It is AM4 socket.

This is interesting, because soon are new models

I overclocked my CPU today at 2.95GHz. The last time I tried more than 2.8GHz i got a blue screen. The only thing that I needed to do was to set the Vcore to 1.5V (1.3625V before). http://valid.canardpc.com/show_oc.php?id=878448

Now, my problem is that I can't go more than 2.95GHz because my CPU need more Vcore. My motherboard (ASUS A8N-SLI DeLuxe) can support up to 1.65V but it allows me only 1.5V.

How can I set more Vcore ?

• Ryzen 7 1800X
  
• Asus Prime B350M-A (BIOS 0502)
  
• 4 x 8GB Corsair CMK32GX4M4A2400C14 @ 2133 MHz
  
• Nothing is overclocked. Everything is stock.
  
• Windows 10 Anniversary Update
  

When I run the Haswell binary from here: https://github.com/Mysticial/Flops/tree/master/version2/binaries-windows

The entire system usually freezes when it gets to:

Single-Precision - 128-bit FMA3 - Fused Multiply Add:

Sometimes, it will make it past that, but it usually ends up crashing/freezing later on in the test anyway.

For those who don't trust the binary, the program is completely open-sourced in that GitHub repo. If you have Visual Studio installed: Open the project, build the x64 Haswell binary, and run.

For me this always hard freezes the computer:

• At all clock speeds.
  
• When running single-threaded, it happens to any core that I pin it to.
  

The questions that I want to answer are:

1. Is this specific to my setup? No - Confirmed by multiple other people.
   
2. Is this specific to Asus mobos or an immature BIOS? If so, can it be fixed with a later BIOS?
   
3. Is this an issue with Windows? The crash does not seem to happen in Linux, but that is with slightly different code due to differing compilers.
   
4. Is this a CPU errata? (I hope not - however unlikely it might be.)
   

---------------------------

Current Testing Status:

All of these are running Windows, and are at stock settings or underclocked.

Confirmed Crashes:

1. 1800X + Asus Prime B350M-A (BIOS 0502)
   
2. 1700 + Asus Prime B350M-A (BIOS ???)
   
3. 1700 + Asus Crosshair VI Hero
   
4. 1700 + Asus Crosshair VI Hero (BIOS 5803) (two sets of memory G.Skill + Kingston - also fails with overvolted SOC)
   
5. 1800X + Asus Crosshair VI Hero (Windows 7) - Once pass, mostly failures.
   

Confirmed No-Crash:

1. none yet
   

For those interested in the technical details, I'm getting hard freezes for all types of FMAs (128-bit, 256-bit, single and double precision). But for some reason, it only affects this particular benchmark. Other programs (like prime95 and y-cruncher) aren't affected despite using FMAs.

---------------------------

Update 3/16/2017:

As much as I had least expected this to be the case, this appears to have been confirmed as an errata in the AMD Zen processor. In other words, the last bullet on my list (and the most serious). Fortunately, it's one that is fixable with a microcode update and will not result in something catastrophic like a recall or the disabling of features.

To everyone pouring in from the various news sites:

• The important part is that a user mode program should not be able to hard freeze the entire system. Because if it can (as is the case here), it makes it possible to perform DOS attacks. IOW, this errata is a security issue.
  
• Don't be fooled by the "Haswell binary". The benchmark is 5 years old and I've largely neglected it for the last 3. So I haven't updated it for Zen yet. Any processor will be able to run any of the binaries if it supports the underlying instruction sets. If it doesn't, the program merely crashes with an, "illegal instruction". Under no circumstances should a user-mode application be able to bring down an entire system.
  

My System:

Ryzen 7 1800x

Asus Crosshair VI Hero

G.Skill Trident Z

1200Watt PSU

and a bunch of GPU`s i wana bench

First it all workt out perfect. Installing CPU, MOBO, RAM and all was no Problem.

I installed Win 10 Home Premium,

updated BIOS on the Crosshair to 5704,

benchd some 2d Benches and uploadet them

then i got 10 E-mails (one of your submissions has been blocked) Win 10 not allowed with AMD Ryzen

I was pretty pissed. But ok thats the Rules.

The next Day i tried installing Win 7. And its pretty much impossible.

USB does not work on Win7 so Keyboard and mouse do not work. (i tried all USB 3.0 and 2.0 Ports)

Asus Crosshair does not have any PS2 Port, so i installed Win 7 on a different System. and tried to boot with Ryzen. And what should i say... it doas Not work.

I have seen the guide on anandtech

How To Get Ryzen Working on Windows 7 x64

but it seems to be almost impossible to use the new AMD CPU`s on HWBOT (wich i have been waiting for Years)

I think there are a Lot of Submissions wich have been blocked and i really think there must be an easier way for AMD user to be compatible on HWBOT.

(btw sry 4 bad english)

Thanks In Advance!

I would like to know if anyone of you have had the idea of fresh DELID an AMD FX 8 ***

whether you have had of winning?

thank you in advance for the answer.

(I is that the die is welded, it is not the problem.)

thank you in advance

I am getting an asus m5a97 le2.0 with fx6300 for 120 usd from the nearby hardware store.

considering I am a noob to ocing

what do you guys think? I got ek supremacy evo waterblock and some serious industrial cooling hardware(pumps etc). will I be able to get atleast some points using the above stuff and get a basic start into ocing

And yes it is overclockable, not by much, but it would be great if you could help anyway.

http://hwbot.org/hardware/processor/athlon_ii_x2_m320

I've a couple of socket A (socket 462) Athlons, Durons here. As we all know it is easily possible to unlock the multiplier. But is it allowed for hwbot benchmarks? I've some Athlon Thunderbirds which are "factory unlocked" (no lasercut on L1 bridges).

Is it allowed to use non-standard multipliers on "factory unlocked" CPUs?

Is it allowed to use non-standard multipliers on "factory locked" CPUs?

my problem is that i want overclock my MV 40 from 1600 MHZ to 2GHZ or higher, but it is in my Netbook, HP Pavillion DV2 and, i can only overclock from Windows, but i dont find any Programm that can Overclock my Processor, i have tried with SetFSB and ClockGEN but nothing works, du you have some Ideas?

Sincerly your Wa1lock

My ram is DDR2 800mhz,cpu-z reporting 390mhz(780mhz).I set it to 667 in bios.

FSB:DRAM is currently at CPU:7

With this setup I get Average 40fps in Dirt2,on ultra graphics.

Now the problem!

If I lower my ram to 400 in bios,it will run at around 270 in cpu-z.

Still my cpu is at 2725mhz,but I get Average 30fps in Dirt2????

Can somebody explain how is this possible,why my ram bottlenecks so hard.How do i find the point at where i will clear the bottleneck
