AWD-IT says it's got 11 in stock (https://www.awd-it.co.uk/amd-ryzen-9-3900x-cpu-twelve-core-4.6ghz-processor-socket-am4-retail.html?wgu=13527_206719_15706351466144_2deb0e58ab&wgexpiry=1578411146&source=webgains&siteid=206719)


But frankly, at that price I'd pass - that's nearly 670 Euro, for a cpu that should be 499.99 RRP.

EDIT: Mindfactory.de also seems to have stock, at a more acceptable price of 537 Euro. EIDT2: They don't seem to sell outside of Germany anymore...

Cannot see any place that would be 499.99 pounds.

It's nearly always 550 pounds or even 589.99 with overclockers

I've never used www.awd-it.co.uk are they reliable?

The price should be 499.99, it's AMD's price - it's 499.99 USD in the USA (incidentally, I was in the US in May...I should've postponed my visit!); Which also means there's no reason it shouldn't be 499.99 EURO (it was initially sold at that price on some German, Spanish, French and Italian stores, including Amazon, when it first came out - the price crept up as soon as it became clear availability wasn't great).

Anyway - search "ADMI Bundles" on Amazon.co.uk if you need a motherboard as well, they seem to have a few R9s bundled with either a B450 or an x570 board. Prices are not bad either, you can choose if you need the RAM as well or not.

As for online sellers being "reputable", I'd say in this day and age ones who aren't don't last very long, it's a shark pond selling online...

Had a quick look at the ADMI bundles. There is some Chinese reseller selling some of the full rigs for like 1/3rd the cost.

I guess it's almost certainly a scam. Hard to resist a punt though :pac:

Most likely filled with parts which had the "bios hack" so they report to Windows as something they aren't - some 2003 entry-level nVidia card pretending it's a GTX1660 and such. You can probably hack a motherboard BIOS to say a PentiumG is a Core i9 9990K as well...then again, the joke's on whomever seriously things such rig could be bought for 300 GBP.


I wonder if the ADMI folks (it's the same company as AWD-IT) know about this "nice" seller.

EDIT: After reading some reviews, it looks like another possibility is that these systems might be made out of defective returned parts...If I had some cash to burn I'd order one to see what the hell gets delivered

Good, means they were already reported for scamming.

The enthusiasm seems to have faded in this thread - I finally got the 3900X; Ordered a mobo+cpu ADMI bundle on Amazon, they are indeed fulfilled by AWD-IT in the UK. Paired it with a DDR4 3200 Vengeance LPX 32GB kid from Corsair (I managed to get it at a better price from a different vendor in Italy).

The mobo an MSI Gaming Edge X570 with the 3900X - boy have they come a long long way, back when I started building systems (1998-ish), MSI were basically the bottom of the pile; Crack open any supermarket-bought PC, and you'd find one of their boards in there.

With a full black finish, all the paraphernalia associated with a gaming-grade board, hefty heatsinks on the power delivery circuitry, the MPG Gaming Edge WiFi x570 looks well built. There's even an USB Type-C port (not really that useful on a desktop, but hey, nice to have) and let me say a word about the integrated backplate: about time EVERY board started having this, rather than keep using the flimsy, sharp-edged little panel attaching unsteadily to the case (hands up whomever ever put the board in only to realize one of the metal "tongues" from the backplate had gone inside an USB or the Ethernet port).

The fan on the x570 chipset is indeed noisy in a high-pitched, Socket-7 or Socket-A fan reminiscent way (remember these fans running at 8000rpm?), but thankfully it's stationary most of the times; By default, it's set to only kick in above 75c and in my tests, the board seems to settle itself at about 65c, no matter what the load is.

Now to the CPU - well, it's a beast, easily doubling the performance of my old (and still very valid) R7 1700. It's also a completely different kind of animal compared to any other CPU I've seen before - in terms of thermals/performance/power management it does indeed behave more like a GPU, making use of any headroom it can find.

I'm cooling it with an NZXT Kraken x62, idle temperatures are clearly meaningless as they constantly swing between 35c and 50c, but it settles itself at about 72c under heavy load (Prime95 small FFT, OCCT Stress test). Used to the cool 25-30c at idle and 55-60c under load of the 1700, these initially looked bad - but it immediately became apparent, via a few searches, that these temps are pretty normal even with an AIO or a performance-oriented air cooler. Moreover, I tried JayzTwoCents experiment with the vCore - Ryzen 3000 simply loses performance rather than crash or misbehave, my CB15 score went from 3100 to 2000, and the difference is not really reported in any monitoring software - while scoring a "paltry" 2000 cb points, both CAM and HWMonitor claimed everything was boosting at 4.4 Ghz.

EDIT: I just found out x470 boards also have the EPS 8pin + ATX 4 pin connector for CPU power, and also on these you only really need to plug the EPS in. I had no idea, never had an x470 board.

I don't want to be calling bullsh1t on an established reviewer, but...well, I have to.

I've run the most recent OCCT stress test, small units, for over an hour (1h23m precisely), and the MOS never went above 80c, reached for a second or two, then it settled at 79c; All set stock and "auto" in the BIOS, with a 12-Core R9 3900X. Worth noticing the CPU was apparently drawing 145W, I have no idea how accurate that'd be. Probably not much. Anyway:

Consider this is in an NZXT H500 case, which is not exactly known for its airflow qualities, with the only intake fans being those on the Kraken X62 (which means, they were blowing in air that's warmed up already); Two extraction fans are at the top and rear of the case.

I'm not sure if the matter was the bios, version or a defective board, but sure enough mine didn't reach the levels mentioned in the review. It's safe to say it's probably not the ideal board for an extreme, liquid-Nitrogen based OC, but certainly it won't just "go up in flames" just by normal use - in fact, I'll be surprised if I ever see these temperatures in the screenshot during day-to-day use, even rendering and gaming.

New bios coming out with updated Agesa settings from AMD for you X570 folks.

What's the general consensus on non-x570 boards with gen 3 chips now? Are all the problems ironed out? Depends on particular combinations?

Had a few problems when I updated to the ABBA bios from MSI on a b450 gaming plus, constant BSOD's, rolled back to the previous version and its been fine.

X570 AORUS ULTRA no issues at all, haven't bothered with bios updates.
