What's your latest tech purchase?

[QuietBob]

Renoir arrived. I wanted to get a shot of an AM4 CPU with the letters bright instead of dark for once:

Nice one! Checking out your bench results in the Zen thread now.

 

[Valantar]

I've got the B550I Aorus AX for the Renoir chip. Feels kinda weird to be using a midrange 4-layer (though stout) mATX as my daily driver while my TV PC gets the 8-layer 90A ITX board haha. Judging from its design and QVL I don't think it should be a limiting factor all the way up to DDR4-5000.

Have you noticed so far any major differences in memory voltages and overclocking compared to Matisse CPUs? I can't find much good info about Renoir SOC aside from BZ channel and I missed his last 4750G stream

I've never used anything Matisse, so sadly I can't help you there. Mine lives in an ASRock B550M-ITX/ac - I considered the Aorus, but given my use case (HTPC) I decided the extra $50 or so wasn't worth it. I haven't touched the CPU clock speeds - I did try some minor offset undervolting to see if I could get it to run a bit cooler, but even 50mV caused it to drop clocks, so I went back to stock. Mine boosted 100MHz past spec when I was testing it with a 212 Evo though, which was nice, but it went down to stock speeds when I got my low profile cooler on there. The reported voltages on my ASRock board are sort of scary - vcore is typically reported in the 1.35-1.38 range, but I've seen it go past 1.4V quite a lot - but IIRC people were seeing similar stock/auto readings for Matisse when it was new, and IIRC this was explained as essentially being false readings due to the advanced voltage regulation used by Zen 2 and that this wasn't equivalent to a fixed voltage OC at the same level. At least I'm hoping that's true, as I'd be pretty bummed if this chip started to degrade on me.

The only things I've really played with are iGPU and memory OCing. I couldn't get the iGPU OC past 2100MHz without pushing the its voltage higher than I wanted to (2100 is @1.2V iGPU voltage, I couldn't get 2300 stable even at 1.3), but it's still a decent bump. DRAM OC was a breeze - 1usmus' calculator got my Ballistix Sport LT 3200C16 (2x8GB, E-die) to 3800C16 (1900IF) at 1.38V and 1.15V SoC. I just punched in the numbers from the calculator and everything worked on the first try.

Dang, for some reason I thought you had a 3600. Yeah, that's all normal vcore behaviour for stock Zen 2, no need to worry there. Interesting you mention the change in clocks with cooler; my NH-U9S is the only cooler I can spare for this 4650G and on every boot it just immediately comes out swinging, straight past 4.3 on every core, 4.2 effective on every core, and 4.3 sustained effective clock on the best few cores. It's at like 61C in CPU-Z bench, haven't done cinebench yet.

Right now it's clocking so high at 3933 16-17-17 that the DRAM calc doesn't even support B-die at those speeds and this isn't even B-die lol. But while this appears to be really stable so far, 3933 (1966MHz) is the farthest that the infinity fabric will go at the stock 1.1V SOC so I think I'll finish my stability testing and leave it here for now. Don't like to push new hardware to the brink without getting acquainted with how it works first.

Sounds like you've got a slightly better sample than me IIRC I had to go to 1.15V to get 1900IF to run. I frankly didn't make that much of an effort with my tuning - there are definitely some voltages I should have googled, among other things - but the cooler affecting things makes sense. The cooler I'm using now is a modded old Arctic Accelero S1 passive GPU cooler with a custom mounting bracket I could definitely have fit a better cooler if I wanted to (my case could fit an NH-L12s or Big Shuriken 3), but none of those are likely to work as well passively as this does - I've set my fan to turn on at 60 degrees, which means the PC is entirely fanless unless I'm pushing it I'll probably get a bit more into tuning it at some point down the line, but it needs to be 100% stable, so I likely won't be messing that much with it.

Did you find TSME in your BIOS and disable it? It's somewhere under either AMD Overclocking or CBS menus in mine, dunno which one it'll be in ASRock BIOS. I only just remembered and I feel so stupid; I had read it months ago while skimming the Tom's review of the 4750G but only remembered today.



It's some additional memory security feature that only Renoir PRO CPUs have (as part of the Ryzen PRO featureset) and kills your latency because the default setting will probably be Auto (Enabled). In membench the difference is pretty much negligible, but gaming perf is not what I'm looking for - the memory validations are what I'm want

Sub-60ns in AIDA even before my B-die arrives, now that's more what I'm expecting from this chip

My board apparently has TSME disabled as standard My memory latency clocks in at 61.5ns at 3800MT/s, so a bit behind yours, but still pretty decent overall. How did you go forward to get yours running at 3933MT/s? I have absolutely zero clue how to calculate subtimings, and 1usmus' dram calc doesn't go past 3800 for E-die, so that's where I'm staying for now at least

I'm surprised your latency is above 60. I couldn't get 3933 stable in TM5 even with 1.59V (HCI was stable from 1.48V) so I'm dailying 3733 1.45V. For some reason 3733 16-17-17 is still 58.5ns AIDA and 113s membench. So no point running 1.59V for something unstable.

I am still running 165ns tRFC so Rev.E might be a lot looser in the 300ns region. Could be why 60ns+.

Calc thinks E-die belongs on Ryzen 2000. At some point between DJR and E-die it just ceased to be a useful tool for me, so I only use it for membench. I guess people eventually naturally wean themselves off the Calc when they start tweaking secondaries and realize some of the Calc suggestions make zero sense. The Memtesthelper guide is good for starting on subtimings, then stops making sense when you start getting into minor voltages. Everything has a beginning and end, I guess.

Heh, given that there are 27 secondary and tertiary timings to deal with (alongside voltages, termination block resistances, etc.) - even if most of them can be left on Auto - I kind of doubt I'll be abandoning Calc any time soon. Just learning how much to adjust the various timings and which ones matter more than others is more than I can be bothered doing right now - I have too much other stuff to focus on to teach myself all of that, tbh, though I'm well aware that leaves a decent amount of performance on the table. Who knows, maybe I'll get into RAM OC for real at some point, but for now I was just looking to maximise iGPU performance - and that sure paid off!

My tRFC setting is 608, so if my calculations are right that's 320ns. Definitely a lot slower. Guess I might see if it can handle lowering that setting some. Your voltages are crazy to me though - what kind of RAM is that? Have to say I'm pretty happy with my E-die hitting 3800 at just 1.38V.

Not that many, only about 15-18. tCL, both tRCDs, tRP, tRAS are your main ones, tRRDS/RRDL/FAW and tWTRS/WTRL/WR for tightening things up, tRFC, and RDRDSCL/WRWRSCL. Shouldn't need to change procODT or CADBUS, shouldn't need to worry about any voltage other than SOC below 4000. Aside from an additional three (tCWL/tRTP/tRDWR), there's not a lot of point in entering the remaining ones not mentioned manually. Be advised that Rev.E is a frequency overclocker but isn't going to win any awards for tight timings, so go for best achievable speed instead.

For tRFC I have yet to notice a performance difference from a reduction less than 100 ticks, I just set it to something appropriate. Much better to start thinking of tRFC in nanoseconds, not ticks. Reous list is my go-to for tRFC, but take its categorizations with a grain of salt:



Mine is Samsung 4Gb E-die. Really old (think Skylake, X99, first gen Ryzen) and you won't find it anywhere anymore. Best described as B-die junior. Somewhat close to B-die on a lot of timings, much tighter than Micron and Hynix kits, but your Rev.E will run circles around my 4Gb E at above 4000MT/s because I'll need 1.7-2.0V to get there, that's not daily stable, and that's not a safe daily volts. For comparison, you said your Rev.E does 3800/16 @ 1.38V, my E-die is 3800/16 @ 1.48V albeit at tighter timings. The price of being old.

My friend upgraded to a 5800X, so I bought his 3700X for cheap. It'll make a nice upgrade to my 2600.

 

[sam_86314]

This has some interesting tech in it, right?

Nice clean 2.5L five-cylinder in my new 2011 Volvo C30 T5. It has around 86,000 miles on it.

It has a good amount of power and makes an incredible sound. Hope it ends up being reliable for years to come.

If it doesn't count, I have a Noctua NF-S12A on the way. Gonna see if Noctua fans live up to the hype.

nice, should be quite a bit of fun with the manual too... assuming its the 6spd manual. plenty of power too

my gpu came in the other day

Sadly not a manual. Still, it's been a very enjoyable car to drive. It's quick and exciting while being comfortable and practical.

So far it seems to manage a slightly better fuel economy than the 1.6L I4 turbo in my previous car, which is interesting.

 

[xBruce88x]

probably something to due with direct port injection and maybe some variable valve timing tricks... and perhaps a better set of gears for the trans

funny enough when we got our Mazda 5 quite a few reviews said it was slow... yet we have a "problem" spinning tires sometimes lol. drive quick enough for a family car and turns a lot better than the old sienna we had. way better. that thing was like a truck... I swear the van I use for Fedex turns better, except for when I drive a P1000 lol. but the mazda was a nice upgrade. 1999 to a 2012, and better perf, handling, etc. though it is smaller inside. the sliding doors are handy for when the kids get older.. dont have to worry about them dinging cars next to us. doors are also super lite to open as well which is nice.

edit:
forgot to ask, did it come with a warranty? we managed to get ours with a 12mo/12k mile warranty for the drivetrain. not bad for a $7k car lol.

Had to order a new HSF for my Ryzen build. Turns out my current one doesn't support AM4, though the product page says otherwise. Loving the green packaging trend:


Try this one for size



A high quality magnetic tip screwdriver is included:



That'll be the fourth Macho in my collection. I find them Machos irresistible. They're soo... manly

Silly naming aside, those coolers are really nice. Love that they're sticking with the widely spaced fins and high airflow too - that lets them work pretty well semi-fanless too.

Bigger engine helps with getting up hills and being more of a smooth drive. I don't see the point in having a big car and a small engine, that just doesn't work at all... Uses more fuel not less... There's always a happy medium so it's just finding the balance if that's what your after

A friend has had Volvo for ages, raves about them You'll be in good hands. When something if it does break, you'll be shouting at the price, but I doubt it'll break again. Just like German or Japanise based cars, they are super reliable (unless you buy a dog) but otherwise, its just the parts that are expensive...

I have been doing pretty well with Customer requests. Gave myself a gift after using an AData SX 8200 Pro 480GB in a build. I replaced it with this for a decent price. I wanted the SN850 but the 1TB was on back order on Newegg and Best Buy. I haven't bought anything from Newegg in a while but they seem to be coming around. My next purchase will probably be the Enthoo Pro 2.

There is nothing wrong with that keep the industry going strong it's called being an enthusiast. I would like to know how you got your hands on some of the hardest silicon to come by? The MSI cards are sweet too. Their coolers are top notch.
