kimcicle posted:Thanks for the reply. I'm not using the stock cooler, and it looks like only the chassis fans were spinning up so I'll mess with the fan curves some more. Depending on the mobo you can look at setting chassis fan speeds based on 'system' temp rather than CPU, which is generally a temp sensor on the mobo chip. On anything but the X570 that hardly varies, so you kinda have to change fan speeds on 2 degree intervals.

I could have sworn Excavator implemented AVX2, but that didn't see much use outside some laptops, a one-off part for FM2+, and the earliest AM4 APUs. But assuming I'm not misremembering that, it'd still be pokey considering the architecture's limitations...

I think I posted about this before, but I got me a monster of a dinosaur AMD FX 9590 cpu (lol) that I successfully undervolted/underclocked? so it can work on my mobo. Ok, so, now that amd released some budget ryzens I was wondering if I should go the new route or try to buy a mobo that successfully supports my my watt monster of a cpu? Anyone have any experience with the new ryzens 3s? Pros of staying: I only need a mobo that actually supports the 220w cpu Cons: Alot of the mobos are no longer made and the ones that are are kinda pricey for an am3+. Why pay $200 for an old mobo when I can get a new am4+ ? Pros of switching: Well I'd have all new hardware that isn't ancient. Cons: I'd need to buy a mobo, ram, and a cpu I actually bought a mobo off of S.A Mart but I can not for the life of me get it to boot up. Nothing. Maybe I fried it on accident? Maybe it was bunk from the git go idk. I aint looking for 4k gaming here. But I am def not getting the full power of my set up and games work fine, but I aint getting many frames in say Call of Duty. It can chug sometimes during warzone. It runs at 30fps but thats not ideal for that game at all.

It sounds like you've already invested in hardware that isn't working with your current setup, and it sounds like you won't be able to recoup that Imho, get all the new stuff and sell the old stuff to somebody else in your current situation.

Investing any money whatsoever into Athlon FX platforms in 2020 is a mistake. The only thing that's good about it is the 8 cores means it doesn't fall over in recent games that dislike 4c CPUs, so there are places where it can outperform a 2600k or whatever. But it's not good. OTOH: ShortyMR.CAT posted:but I aint getting many frames in say Call of Duty. It can chug sometimes during warzone. It runs at 30fps but thats not ideal for that game at all. This suggests to me that your video card is choked, because a 9590 can still keep ~60fps in battlefield 5 and codblops 4. Though I guess it depends on how much you had to underclock it. If you're running it at like 3ghz to not burn out your mobo that would definitely be the reason. But I think you're probably also running too high res / detail for your system.

I don't think so today, but back in 2017 when ryzen was having a promising but slightly rocky launch? The 9590 was a lot of CPU for the price AMD was selling them for back then. 5ghz for $100, what's not to like? As long as you bought the special mobos that could run them... and a bigass water rad... and didn't mind the small sun worth of heat... and totally ignored the potential of Ryzen to improve vs a 4-year-old CPU that was going nowhere.

The Excavator / Carrizo type is a pretty different kettle of fish though, those things were pretty much made for the low-cost NAS box.

I can't find any details about planned cheaper models that would compete with normal HEDT prices. The 1900x and 1950x are basically living in the previous HEDT price segment. There's a big gap between the 1950x and the 3960x, though $1400 for a high-clocked 24 core part is pretty sweet... even if I'd end up underclocking it by 5-10% to tame its power usage.

I woudn't call it merely expensive, not insanely. People who truly need that kind of power/IO are working on projects worth much more than the cost of complete HEDT systems, regardless of Intel suckery. Also only 1 in every 20 Zen dies gets put onto a TR part and they use more of them.

You can make an argument for as low as $600 - after all it's also 4x 3600 dies, that's $160 a pop (swapping 4 io dies for the single larger one). Even at $700 would they make a better profit margin than selling those dies as 3600s. But if it were $800 then OK, I guess that's fair. Paying double the price of a 3950X, a CPU that is already completely off the price-curve for the rest of the lineup, for cutdown chips, is a ripoff. Cutdowns are cheap and easy to produce - this is why Intel was willing to sell you the 5820K for the same price as a 4790K. The 4790K has to be absolutely perfect, the 5820K can have two broken cores and still be a 5820K. It actually makes complete economic sense for a cutdown HEDT chip to be cheaper than a "perfect" consumer chip. That's how the cost of production works out. And the truth is that in the server market where AMD is facing much stiffer competition, they are much more willing to price aggressively. The Epyc equivalent to the 3960X is the 7402P, and those have always run several hundred dollars less than the 3960X (actually have been as low as $1050 before). Yes, it doesn't clock as high, but it has advantages in other areas as well (twice as many lanes, twice the memory channels, RDIMM support, all for less money than the Threadripper). Basically server chips have historically always been much more expensive than workstation, so you wouldn't buy them unless you had a really good reason. That situation is now reversed because AMD doesn't really feel the need to compete in the workstation market, so you should give real thought to whether you really want a super high clocked chip or whether you'd rather be running RDIMMs and more memory and more PCIe devices, because you can get much better capabilities in those areas for less money if you are willing to yield some clocks. So I mean, AMD's own answer to "what is it actually really worth" is at least 30% less than what they are currently charging, because that is what they are willing to accept from enterprise customers for the same exact chunk of silicon. Oh and put back TR4 support while you're at it. Despite all the excuses they "just coincidentally" managed to make that work on Epyc, but nope consumers gonna have to buy a whole new board. Klyith posted:The 3900X and 3950X are your HEDT CPUs for "enthusiast HEDT" prices. HEDT has always been about IO more than core count.

So with an impulse decision to upgrade to 32GB of RAM, I got a chance to try out messing around with Micron Rev E./E-Die RAM. I am extremely impressed with it and have actually found it to be much easier to overclock than my old Samsung B-Die, though I do believe that was in part due to my old B-Die not being the best binned while my Micron looks to be excellent binning. Pairing this RAM with a 3900X. I've got 2x16GB sticks to replace my old 2x8GB sticks, since going 4 DIMMS on a daisy-chain board was likely to force me to drop RAM speed significantly. Ended up getting the Crucial Ballistix RGB DDR4-3600 2x16GB set, cost a little under 200 dollars, a few bucks cheaper than what I paid for my old 16GB of B-Die. The RAM booted at XMP settings perfectly, which is not a guarantee on Zen, even on Zen 2 CPU's. The RAM is DDR4 3600 16-18-18-36 XMP, but handled DDR4 3600 CL 14-17-17-17-34 perfectly. It also looks like it's handling DDR4 3800 CL 16-18-18-18-36 well in my testing so far. Getting latency of 66ns in Aida64, only slightly worse than the B-die, with my memory speeds being even slightly higher than my old B-Die at 3800 with better timings, likely due to the benefits of dual rank vs single rank. In some game testing it looks like the E-Die is actually slightly performing the B-Die, with the dual rank pushing it over the edge. So yeah, gently caress B-Die if you aren't literally aiming for the last percent of performance. I got the B-Die in the first place as I don't think E-Die was out yet and on a Zen/Zen+ CPU's that I was using before getting a 3900X, it was pretty much B-Die or bust if you wanted to run anything past 3200 or so without hating yourself. E-Die is half the price and 95% as good. I'm extremely pleased with how easy it was to work with Micron E-Die.

Team has a “Za Dark” 4000 C18 2x16 gb kit that Newegg carries for $170 that has been tempting me. It’s reportedly micron E die but like, that’s also less than half the price of an equivalent Samsung B die kit. How much worse is it really in practice? Can’t be that bad right?

Yeah I can easily do 3600-3800 on mine (CL16 to CL18) but my 2700's IMC/IF kind of loses it's poo poo about it. E-Die likes it's some voltages and looser timinigs than B-Die, but it also likes to go fast asf and can run pretty drat hot and not give a poo poo. Also buying Crucial now pretty much guarantees Micron-E die on anything above CL15 3000.

Hey, so I'm looking for some Ryzen upgrade advice. Currently my main desktop looks like this:
And I have been thinking about upgrading the CPU to a 3900X. I mainly use this computer for software development + general internetting , and don't really *need* something faster, I'm just itching for more cores+Hz for the fun of it. If I go ahead with this, I'm also thinking I might just keep the 2700X as a secondary system, and use that to finally retire an old rear end 4770K that I still have. So this would mean getting another motherboard + RAM at least, and I think I'm fine just transferring over the case, PSU, GPU, and drives that the 4770K is currently using. Even after getting seriously burned on an impulse buy "ASUS Prime B450 Plus" and basically writing that off as a complete loss, I did a bit of research and settled on that TUF as the best value in terms of very solid VRM and upgrade potential. (Fool me once, take my money I guess? But I seriously cannot stress enough how awful that Prime motherboard was, and the endless headaches/ system instability I suffered through before finally determining the culprit and upgrading). Anyways the TUF has been rock solid for me, and I'm very satisfied with it. So if I end up keeping the 2700X for a secondary, partial re-build, then I'll probably just get another... or maybe a B550 version of the same. So I guess my main question is regarding the newer B550 variations (which could save me up to a whopping $20!) if there's any reason not to get one? I don't really get much about the differences, but as far as I understand:
I got my TUF X570 no-WiFi for $165 back around mid Feb, and looking at pcpartpicker, it seems the best price has gone up $15 since then. At the moment I'm seeing these prices: $160 - B550M $170 - B550 $180 - X570 $180 - B550M (WiFi) $190 - X570 (WiFi) So should I bother with the penny pinching on a B550, or even possibly B550M(mATX), which still has 4x dimm sockets too apparently? I don't care about builtin wifi either, I just figured I'd show those models as a comparison. Lastly, and tying into recent discussion which got me thinking about upgrading again: for the RAM of the newer build, this Crucial 3600 C16 2x16GB looks like a decent deal?
