AMD Ryzen 7 9800X3D

LTTs comment, or lack of, was interesting on the WAN show.

Q: "Should I go with a 9800X3D?"
A: "We know too much, no comment, watch/read reviews before buying"

I'm taking that negatively, but maybe it's the opposite, so who knows. Let the theories fly!

Similar and take it for....whatever it's worth. Jayz comment on his Intel Ultra review vid seemed positive as he said the 9800X3D was going to make the benchmark charts he was showing "look very small" when it goes live.

I'm expecting great performance just have to consider if it's enough over the 9700x given its around £300.

Indeed, it's a sign that the unit is faulty, and it might be time to consider the Zen X3D. It seems many will be making the switch as well.

It's a shame, as it was a bargain.

Odd behaviour though, doesn't crash, just literally reboots, no bsod etc, just goes straight to a black screen then the normal boot as if nothing happens.

Then can stay on for 10-15 mins then it ends up doing it over again.

Probably has one or more cores that ***** the bed. Try going into the BIOS and the PBO menu. Set PBO to Advanced/Enabled, go to Curve Optimiser and set to enabled, set to all core positive, and set a value of +10.

Save and exit the BIOS and see if it helps.

So far... So good, no reboot :o

Is this setting likely to hinder performance somewhat I assume?

I'm currently running a stress test on cpu-z and it's boosting all cores to 4.9ghz with a max temp of 79 degrees.

This is why I earn the big bucks. :p

You can attempt to lower the positive curve optimizer until the issue reappears. Increasing the positive curve optimizer results in slightly lower clock frequencies. Conversely, a more negative curve optimizer allows for slightly higher clock frequencies.

It's highly likely that the issue is caused by one or both of your two best CPU cores on CCD1. For another test, turn off the all-core positive curve optimizer and switch to individual core mode. Increase your two highest-rated cores by +10, and set the remaining cores to a 0 curve optimizer. Then, test again.

It's possible that the problem is caused by just one core. If you're particularly unlucky, it could be both of the top-rated cores. Through trial and error, you'll be able to determine the cause, if you decide it's worth the effort.

You can identify your highest-rated cores using either the Ryzen Master Tool or HWINFO64.

In the example above on my 9950X, my two best rated cores are Core 1 and Core 5, with Core 5 being the slightly stronger of the two based on the maximum frequency it achieves.

Absolute legend you are, it's still on and running fine. I will do the above too and see what else I can find.

What would you do? Return? 6 months warranty.. Bare in mind, I paid no way near the rrp for this :p

You're welcome. :)

How much did it cost, and what led you to opt for the 16-core variant? If gaming is your main use, the 9800X3D might offer better value.

You could try an RMA replacement directly with AMD; they might help you. Just be sure to provide the original purchase invoice and serial number. They'll probably ask you to troubleshoot first, so prepare for that. Alternatively, you could return it to OcuK for a possible replacement, if available, or a refund.

It cost me £300...so you can probably see why I opted for the higher core count, because why not at that price.

I wouldn't get a replacement from ocuk as its B grade and was the only one there, refund is an option, but this is less than a 9700x right now. Amd rma is a good shout but not sure how fast they are at sending replacements?

After completing the troubleshooting process, if the RMA for a B Grade item is approved, it should take no more than a week, provided that the item is in stock. Additionally, consider that reselling this part in the future may be challenging due to this issue. Something to ponder I guess.
 
Aah, for that price I take back my "return it" comment.
That's probably the reason it's in B grade, someone else wasn't happy with it
 
Will the new processors slot into existing AM5 motherboards? I’ve never had AMD but I see A620, B650, B650E, X670, X870 and X870E and have absolutely no idea what any of that means, I know I want to upgrade from my aging 6700k but no clue what I need to buy, I want to spend around £4K when the new GPUs drop and get the best available CPU at that time.
