If only Linus Torvalds read this tread then only he will know how unreliable AMD is.

To be frank, there are posts on this thread that overblows the issue a little too much. Just like the Intel hate threads on reddit and OCN, lots of bs that is overblown there too.

It's just the nature of the internet and open forums.

Should just stay between 3600-3800mhz CL16 with tuned sub timings for Zen 3 anyways, don't need to go higher. Eventhough I'm doing 4000mhz, it wasn't easy getting here and the difference is quite small. If you're just gaming, you won't even notice it.

@JohnLai
Use a negative voltage offset for time being until you can get a better cooler. Just a -0.1v can bring temps down by 5-8c with no change in perf.

Hey guys, not sure if its okay to post here but maybe I could get some hindsight.

I've been wanting to buy the ryzen 9 5900x , but of course sold out since launch.
As of today, I checked again and I am seeing in Lazada and Shopee that 5900x is becoming available again, BUT with much higher price.

5900x should be at RM2,499 but I'm seeing as high as RM4,000, from china. Lowest I've seen is around RM3,399.
Do you think 5900x CPUs are getting back on stock here in malaysia?
Are those regular prices, adjusted because of the pandemic?
Or are those still scalper prices?

There's no way I'll pay scalper price, but if the regular pricing here in malaysia is, for example, set to RM3399, then I guess it is acceptable to buy.

@bolded

This right here is one of the reasons why the price has increased. If every seller scalps at a pre-determined price (let's take 3399 for the 5900x), then suddenly that price becomes the new "SRP". There is no law or control of the item which must be set a fixed price.

In other words, if everyone is scalping and you don't, then you're an idiot.

To answer your question, no RM3399 is not the new SRP for the 5900x. It's simply a price that has been agreed by all major retailers to scalp at.

It still is and will always be. But by the time a cap runs out, it'll be time to replace the PSU anyways.

There should be another round of major BIOS update to enable ReBAR support for nvidia Ampere cards for Zen 2/3 soon. Here's hoping they stamp out all the niggly annoying issues by then.

Note to everyone, buy AMD products only 6 months after launch.

Those wanting to buy Zen 3, just wait it out a few more months first. The next major AGESA update will be important. Don't be an early adopter.

took them so long.. hopefully will solve my bsod errors on my 3600....yes zen2.

Still getting them at random but very rare. Despite having done over 100 hours of memtest86 and stress tests stable. It will occasionally surprise modafukaaa and goes poof when light browsing or enjoying some music.

I think Zen 2 they diam diam sweep under the rug already, hoping people will forget about the issues or for the vocal ones being so minor that no one would listen to them anyway.

I believe the next AGESA will be the last release that is optimized for Zen 2, beyond that I'm sure they're moving all their efforts to Zen 4 while doing fixes that no one cares about for Zen 3.

sigh.. i dont know what to expect already, did what i can and still happens once in a bluemoon. Most users will probably just shrug it off, but it can be super annoying especially when Im in the middle of doing something when it crashes randomly... like drafting a letter and all the progress gone if forgot to save ughhhh. 

Welp it is a bitter sweet experience. No doubt the performance is damn good for the price when it first launched paired with a B450 despite having some minor issues. Now with intel's price slash and the expensive B550 mobo which i just upgraded into hoping the issues will go away.... i dont know what to feel anymore.

Yeah completely understand that feeling, not knowing when your system will crash. The cold boot bug still bites me once in a blue moon too, don't even know why lol.

AMD really is like playing with fire.

yes I also got same cold boot up then hang sometimes.  blush.gif

not sure why and how to fix but lucky the system overall restart is fast. hehe

It was thought at first to be unstable DRAM clocks and timings, but from what I've experimented is that even on bare bones stock JEDEC certified clocks and timings that AMD adheres to in their official spec sheet, the cold boot bug can still happen.

Then the next logical troubleshoot is voltage for SOC and IOD, increasing them doesn't stop the bug. Using stock doesn't either. Undervolting, nope.

So after that let's check AMD's OC parameters which relates to PBO, nope. No matter if PBO is enabled or disabled, whether a low or high scalar setting is used, cold boot bug can still happen.


QUOTE(Cold|Drawn @ Jan 17 2021, 09:26 PM)
what's a cold boot btw?

System simply refuse to POST. Have to power cycle (in my experience at least) to fix. It's not system breaking or anything, but annoying. Sure booting up to windows is quick, but this shouldn't even be happening in the first place.

all the old amd systems that i ever had like the athlon 64, semprons, athlon x4, etc doesn't even have much stability issues...

The difference with ryzen is that they're pushing with a new product way too fast. I mean, the fact that they're already talking about Zen 4 having a possibility of a 2021 launch (which is almost impossible, so basically it'll be a paper one lmao) says it all. There is not enough time for the platform to mature and then x570 and AM4 is going EOL by the end of the year too.

They chase numbers and new products because that's the only thing they can do to topple Intel, that they did as is evident with their profit earnings and rapid stock increase over the last 3 years.

By and large, personally I don't have any major stability issues on my end either.

Do this and your temps will go down even more plus perf increase , I did that and got lower temps and faster performance as well. But remember to test the stability of it. I adjusted and then played games here and there no issues but somehow my pc will auto restart when I'm doing nothing much like surfing the web. So yeah test your stability after tweaking it.

Moron tuber doesn't understand how to undervolt, makes a video as a blind leading the blind.

You misunderstood. You can certainly do it the way he's showing in the video, it's just that his video is riddled with misinformation as always (just like all his previous undervolting guides, some of which he had to take down).

He claims that @10:30 if you want to "undervolt traditionally" you need to lower all the other limits on the motherboard as well. This is untrue lmao. You can still set a negative offset while maximizing the VRM limits and still get an undervolt, the CPU will still be able to boost to its max clock speed if an app needs it. All the user has to do is to make sure they have sufficient cooling so that the CPU doesn't run into thermal throttling. He doesn't make this clear at all and shrugs off other methods and says his is the best, that's what blows my mind.

I'm also damn sure his undervolt of -30 is unstable in real world usage. Benchmarks IS NOT an indicator of stability, he however believes it is. rolleyes.gif

Did my 5900x undervolt according to this video, -30 counts and yes, my system rebooted a few times even when I'm watching Netflix like 5-10 mins from system bootup.

Then I reduce the count to -25, now it's running just fine and TimeSpy benchmark has improved over stock setup on the CPU.

Cheers all.

Keep an eye on your event viewer at least for a week to spot any event errors. You may not get a bsod or random reboot, but there may be other errors cropping up that you aren't aware of.

Hitman 3 eat up cores like a pig that hasn't been fed for a week. Amazing multi threaded usage.

It does tho.

Look at that workload spread out to all the threads. Hitman 2 wasn't anywhere near this and that game used CPU threads fairly well for its time.

No I haven't bought it yet, doing so tonight.

I'm not saying it's heavy on the CPU, I'm saying that it spreads out workload very nicely on all cores.

its not bro.. its more of a 8/16.

i tested it on 10/20.. the spread becomes uneven.

Your screenshot shows about 36% as the average for all the other cores after core 0 and 2 though? That's not bad considering in Hitman 2 they were barely managing 20% with DX12. That was one of the letdowns of that game when Hitman 1 GOTY was doing much higher than that.

You bring all the reported issues to reddit and people both on intel and AMD subs will curse you to hell. Then say what problems? I've been running fine since day 0! Learn to use a computer.

This is why AMD sells.

That's true. I'm sure Zen 2 would still keep selling like hotcakes even if Zen 3 wasn't released last year. AMD like die die want to release something that isn't ready yet just to get the e peen points over intel.
