I've run into the same problem with Corsair Vengeance LPX RAM, twice. My Plex server only supports Vengeance LPX ver 4.31 DDR4-3200, but when I ordered the same part number online to add another 16GB, I received ver 4.36 or something, and I can barely run the RAM at 2933 MHz. I think I got them in the wrong slots, but it detects it in BIOS as 3000mhz? Anyways its only an office computer so whatever JEDEC speeds are probably fine for now. I'll try the other ram slots with COPD speeds later.

QVL lists usually don't matter. Be sure to update your Bios to the latest version, that might help. And use the slots recommended in the mainboard manual, as suggested. The RAM might also simply be defective and not run stable at full speed. teagone posted:My Plex server only supports Vengeance LPX ver 4.31 DDR4-3200, but when I ordered the same part number online to add another 16GB, I received ver 4.36 or something, and I can barely run the RAM at 2933 MHz. If your RAM is dual-rank, that is the reason - not it being incompatible. Running four dual-rank sticks is like running 8 single-rank ones, which consumer CPU memory controllers can't do at high RAM speeds.

See the following regarding my friend's issue with trying to get his Corsair Vengeance LPX sticks to run at their rated speed: teagone posted:
I had similar issues trying to get my own ver 4.32 DDR4-3200 Vengeance LPX sticks on an MSI B450M Mortar board (latest BIOS) and a Ryzen 3 2200G to run at 3200MHz. I could only ever get the sticks to cap out at 3000 MHz on my Plex server; this was running with ONLY the ver 4.32 sticks installed. If I ran the 4.32 sticks with the 4.31 sticks together, I could sometimes boot at 2933MHz, but if I ever had to restart it was 50/50 if the RAM timings/frequency would stick or do the memory fail boot loop to reset the timings back to the JEDEC speed. I can run the 4.31 sticks at their rated 3200 MHz speed without issue... because that specific version is on the QVL of my Plex server's motherboard. [edit] Also, Corsair's RMA department won't/can't swap your sticks with the proper version if you didn't get the version number you wanted. Because of that interaction I had, I'm personally never buying or recommending Corsair RAM again lol. teagone fucked around with this message at 12:55 on Aug 16, 2020 |

Zen+ doesn't have the world's greatest memory controller, and Zen 1's even worse. In my limited experience Zen+ tops out at 2933 without getting into the weeds, but the performance difference between 2933 and 3000 or even 3200 will be imperceptible in all circumstances, so I wouldn't worry about it.

Get QVL RAM for Ryzen. The small premium you have to pay in money and time is worth it when you could end up being the guy fiddling with memory timings to get it stable.

You're really limiting your 0.001% lows. If you want to dampen the impacts of that without having to remount your cooler, you could hang these satchels filled with a specially compounded silicate that's designed for that very range. Normally I'd recommend checking out brazing your CPU cooler directly to your lid, but it obviously seems like you're not ready for that kind of commitment to computing if you're already using cheapout shortcuts like thermal paste. I hope I'm not sounding too harsh, but you'd obviously benefit from lurking more because this is really basic stuff and I'm embarrassed for you.

The thing is you don't get to pick what version of Corsair Vengeance LPX RAM you get from whatever vendor you're ordering from online. So while the part number for the Vengeance LPX is on the QVL, you're basically playing the lottery when it comes to what version you end up with because of Corsair's aforementioned lovely inventory practices, unless you physically got to a Best Buy or Micro Center and ask the employees to look for the specific version of the LPX kit you need... which is dumb, and why I now won't recommend Corsair RAM for any potential Ryzen builders.

Not as finicky as AM4/Ryzen I don't think but still, it's been good RAM.

XMP is really just a suggestion of how far they can be safely pushed to most of the time, but everyone markets this as if it was JEDEC. To be fair, it feels like XMP from Intel is a tighter standard than DOCP from AMD. I haven't heard of people not getting their timings on the newer Intel stuff though that simply could be they aren't moving large volumes so we don't hear about issues that don't occur. Also if a RAM manufacturer is selling you RAM at rated speeds above JEDEC, they better deliver or you can refund it as a faulty product. Otherwise, they can't be segmenting their product stack like they are doing.

MikeC posted:To be fair, it feels like XMP from Intel is a tighter standard than DOCP from AMD. XMP isn't a standard of quality, it's just some info on the ram module that tells the bios what speed settings to use. That's all the standard does. DOCP is the exact same thing, but XMP is trademarked so AMD doesn't call it that. Plenty of AMD mobos call it "XMP" in the BIOS of their AMD boards anyways. The the memory maker can put whatever specs they want in their memory, there's no enforcement (other than reputational and cost to the store for returns) if it doesn't work. They say that such and such product is XMP 3600, and on most modules in the fine print somewhere it says "validated on Intel Core platform". The difference is that Ryzen's memory controller sucks compared to Intel's, so memory makers choose Intel as the main platform to claim their validation. DDR-3600 memory that Ryzen can barely run, or can't run, will comfortably work on Intel, in a crap mobo, on a unshielded benchtop case sitting next to a shortwave ham radio set. The issue is 100% with Ryzen, which is why we look at QVLs. If things change and with DDR5 the AMD memory controller is way better than Intel's, you'll start seeing "DDR5-6900 *Validated with AMD Ryzen 6" real quick. And there will be "for Intel" branded memory that's $10 more for the same spec. But speaking of reputational damage, I've stopped putting Corsair memory on AMD builds in the PC build thread because of their version shenanigans. Selling DDR-3600 that can't run on Ryzen is fine, that's our lookout. Selling a product where you can't tell whether it is QVL or not is not fine.

QVL is just whatever their validation group did interop with, and it would be impossible to do all options. It would be interesting to know what failed interop but that’d never be made public outside of select customers.

QVL lists are the same thing as you going on to the internet and googling if X memory kit will work with Y motherboard and Z processor, it's just already compiled into a list and hosted by the motherboard manufacturer. Either way, don't buy Corsair for memory. (I actually think you shouldn't buy Corsair for ANYTHING at this point, see my earlier posts about the loving power supply that shat itself before the warranty was out and was replaced by a Seasonic unit almost ten years old by this point without a hiccup.)

I still think Corsair PSUs in particular are a good & reliable brand. I think there's been a spate of higher DOA rates across the board for everything from pandemic disruption -- in the PC build thread there's been more reports of that for mobos, ram, and all sorts of things. OTOH Corsair overall isn't my favorite for non-PSU gear, as I think they do a lot of premium brand positioning without always backing it up. I have a corsair case that I got for my old parts / guest PC, which was very much Corsair's version of the Fractal Define C (very compact ATX). I was kinda disappointed with it in comparison with fractal cases I built for other people, in a lot of the small details. Bulky and awkward plastic PSU shroud (but also removable, so I threw it away). Crap drive sleds. Dust filter behind an over-stiff front panel that broke one of the plastic tabs trying to get it off. It was on sale for a fair shake cheaper than the Define, but normal prices were the same.

Corsair SFF PSU's are legit good, and have a decent cable selection from the manuf, even if it is a PITA to navigate compatibility (because PSU + i have a tiny brain). I just use Gskill for RAM. I only deviate away if they don't have something in particular I want.

We buy a lot of PSUs for work and used to get corsairs and moved to the full modular evgas. Fun fact, you can plug the modular pcie cables in to either supply (keyed the same on the psu side) while the 12V and Gnd pins on the output side are flipped! Lol. I have a lot of corsair gear, I like their mechanical keyboards, they were a really good price point for a while. Might be better options now though.

Yah always always check. In our case it wasn’t too bad because the evga ones were braided cables and the corsair were the flat plastic coated ones so it was easy to spot them once you knew. But that first plugin, lol (blew up a diode with a flash but otherwise the board survived)

Quaint Quail Quilt posted:Same, I got a Corsair RM650x, 650W, Fully Modular Power Supply, 80+ Gold Certified for Covid pricing a few weeks ago, since mine was pretty old, it was DOA, I RMA'd it and my old Seasonic was 750 watt and still in the 10 year warranty so I'll wait it out another year. It's not even a COVID thing, the PSU had been in this computer that I'm presently running just fine for almost three years. The only change made was that I bumped the card from a 1050 ti (bus-powered) to a 1660 ti (single 6-pin) which would make the power supply crap itself after about half an hour under a moderate load (I hesitate to call FFXIV a "heavy" load, under any circumstances), or just about as I'm running up on the final boss of a dungeon in FFXIV, thus entirely obviating the point of running the dungeon in the first place.

From Hot Chips, AnandTech covering some of the APU stuff coming out in more detail now. X-post GPU thread for obvious reasons. Interesting situation with the new consoles being more or less contemporaneous with the state-of-the-art for PC gaming — Zen2 cores, plus fixed-function accelerators for audio, storage and other functions. Wondering how games will map to PC levels of performance offered; would a current-gen Threadripper with its extra cores make up for the HW accelerated audio processing and storage decompression?
