Ya its 16-16-16 samsung bdie. Could only get it run at 3200 tho on the old 1700x. Hope the new cpu helps that. Some say its more the mobo than cpu tho but Ill see.

[Nunz]

Why would you buy better RAM if you have 3600CL16 b-die? you could easily get that running 3800, which is probably all you'll be able to run on the 5800X3D anyway.

[pax]

Im shopping for ram and can only find cas 18 at 3800 and up... They stopped making bdie a while back or just forget about the cas 14 timings because they were too aggressive and unstable?

Im not finding any cas 14 ram unless it at 3200 or lower. Havent shopped ram in years so its kind of odd to see latencies have increased.

[Shapeshifter]

Pc partpicker shows lots of stuff at cl 14 all the way up to 4000 kits. It's quite expensive but when you compare it to a high end ddr5 kit it's not as bad.

They still make BDie. There's plenty of CL14 ram available .. I'm not sure where you're looking.

[pax]

Newegg and amazon up here mostly but the cas 14 stuff sure there is some but its 3200... Im not seeing 3800 cas 16 even.

Ive been looking up the bdie stuff:

Was waiting for 5800X3D but Microcenter has 5800X for $270. Can't pass that up. $180 more for 9% ???

[pax]

Wow 270$ man ya Id drop the x3d too for that price.

[KAC]

Pricing sucks dick on 5800x3d.

5800x has been as low as 250 in recent months. So 270 is an OK deal.

[Nunz]

I'd take a 5800X at $270 over a 5800X3D at $450 all day, every day.

looks like someone managed to overclock one.

Problem is that it's voltage locked though, so I wouldn't expect much headroom. But hey, if 4.8 is stable that's a pretty impressive performing chip.

[Nagorak]

Pax, if i were you I'd just stick with your current kit. There's nothing out since then that's really better. There are kits sold with better timings, but usually it's because they've pushed more voltage into them (like 1.5v). In terms of bins 3200 CL14 or 3600 CL16 is just about as good as it gets, with it mostly just coming down to luck of the draw beyond that.

If you manually set your timings you should be able to get 3733 or 3800 (whatever the CPU will do) at CL14-15-14-14-28-42, TRFC probably 270 or so, at 1.45v. You may want to add a memory cooling fan if running very tight timings, since b-die becomes increasingly unstable in the mid 40s C, but other than that you should be good to go.

Once you manually set the timings the difference between dual rank and single rank is also only 1-2% I mention this because a lot has been made about getting dual rank, and there is a substantial difference at XMP settings, but it seems to be mostly because XMP settings are very loose. Once you manually tweak most of the difference goes away. Maybe you hit other limitations like IMC.

So, anyway, besides capacity you have about the best DDR4 you can buy already. For gaming 16 GB is still more than sufficient.

[Nagorak]

Looks like TechPowerUp got their hands on a chip early and have their review out:

https://www.techpowerup.com/review/amd-ryzen-7-5800x3d/

Basically it trades blows with the 12900K and 12900KS: all are within 1% in terms of the average, with the actual results varying by game.

Overall 12900KS looks like a real waste of money to me. Either of the other two are more or less equivalent to it for a lower price. 12900K has more cores for non-gaming tasks. But 5800X3D is cheaper and can slot into existing AM4 motherboards for those who already own one.

In terms of value for money it's hard to argue with a 5800X at half the price, of course. None of these are the best value options.

[demo]

I'm interested to see how common stable bclk oc's are. With a small bump to frequency it could certainly be the fastest gaming chip across the board.

Ya I did find a 4000 kit with cas 15 but it was at 1.5 v ouch and its about as pricey as ddr5 so... I guess I save my pennies for am5.

Theres only a 75$ CAD diff in price between the 5900x and 5800x and the 5700x is only 50$ less than that right now so if the 5800x3d matches the 5900x Ill go for that.

[Nunz]

I would get a 5700X. It's by far the best value of the Zen3 line right now. The 5800X3D really, considering that only few games benefit from the cache and there's no guarantee that future games will, is overpriced at $450, imo.

The 5700X is the price the 5800X should have been to begin with. Super solid deal for $319.

[Nagorak]

There's a decent chance that a 5700X can be made to match the performance of a 5800X by just enabling PBO and setting AutoOC to 200 MHz. Even if not the difference in performance isn't a whole lot, so an argument can certainly be made for the 5700X.

[Megaman]

Pretty sweet for gaming results.

Very impressive showing in the games that utilize the cache. I'm super interested in the GTAV and Red Dead Redemption results - looks like the Rockstar engine scales very well.

Farcry6 does not surprise me as Ubisoft engines typically loves AMD anyway. Though, I will say, the increase in 1% and 0.1% lows are more important than the average, and even in games that did not scale with the cache (ex: CSGO), the 1% and 0.1% lows are still going up.

I don't get Steve's obsession with the 12900KS though. It's just a binned 12900K for extra $$. The chip is essentially for hardcore OCers that are trying to get better chips for XOC. No one in their right mind would buy it for ~$200+ more than a 12900K just to cheat silicon lottery for their gaming rig

When you have more money than you know what to do with, those kind of arguments go out the window. I'd buy a 12900KS if I was putting Audi R8s on order brand-new from the factory too.

I also bought my 12900KS to replace a 12900K. It's something new to play with.

My Audi R8 is a poor man's no option base model. I'm almost embarrassed to drive it.

Actually, It's not really mine. I rented it so I could post photos of it on here to make it look like I own it.

Oh, here we go. It's happening.

Anyway... How about them AMD 5000 series processors. I heard they're pretty neat.

[KAC]

Newegg has 5900X at about 380 cockslaps.
Best deal in town.

[demo]

I'm impressed. Seems like the best option for a gaming rig atm.

Curious to see more bclk oc's.

[Nagorak]

If the issue with overclocking is too much voltage potentially harming the VCache, I don't understand why they didn't just disable the voltage adjustment (and maybe the PBO limits), but still allow us to use curve optimizer and auto OC frequency offset?

At least some chips must be good enough to be able to do higher frequency at stock voltage. Manual OC hasn't been the way to go on AMD since Ryzen 3000 series anyway.

[Nunz]

The voltage adjustments are locked to 1.35v, if I'm not mistaken.

You can OC through bclk still apparently. Someone got one up to 4.9Ghz

[Megaman]

The voltage adjustments are locked to 1.35v, if I'm not mistaken.

Correct

[Nagorak]

It's just kind of annoying having to use BCLK instead of the more direct tools available.

[Nunz]

It's just kind of annoying having to use BCLK instead of the more direct tools available.

The 3D Cache was made on normal 7nm (not finFET), and apparently less thermal resistant than the CCX and IO die. I think AMD's approach to locking out CPU OC was stupid (there were better ways to restrict it), however I do understand that AMD is trying to reduce the potential for RMAs due to users burning up the 3D Cache.

From what I've seen of the design, all the heat from the entire chip is transferred through the 3D Cache to the IHS. You're talking about a LOT of voltage and heat flowing through the cache.

Personally, I believe in unlocked OCing for all. Free the nipple! But in this case, for the first "test-run" of 3D Cache implementation, I kinda get where AMD is coming from.

[pax]

Theres inactive silicon chips on either side of the cache chip to level the cpu that also transfers the heat but the problem with any 3d stacking will be heat dissipation. They have some ingenious ideas on how to do it as they stack more dies in the future but the perf we get from such stacking will be well worth the loss of ocing.

If they can remove the factory ihs and put in a custom copper ihs like the rockitcool kit maybe the temps can be brought down a bit.

Hope derbauer tries that.
