My Threadripper build experience so far. Reseat your CPU


#1

I just built a 1920x Threadripper computer. Asus zenith extreme, 32 gb ecc hynix ram (yes, I know…) 1050 zotac gpu (not a gamer), 256gb M.2 for boot, and an intel P3700 1.6 tb nvme drive I scored on ebay for cheap.

The 1920x was bought on ebay, however the first seller I bought from tried to scam me. Just sent me the box, and then tried to sell me the processor for $50 bucks more. Inside the box was a piece of paper printed to look like the 1920x. And he must have steamed the glue on the cardboard ring to get the processor out, as the security seal was intact. Ebay was great with the refund process. Immediately found another for the same low price, and the seller was awesome!

The Asus zenith extreme was also an ebay purchase, as untested parts only return. From the pics, the pins looked good, so I took the gamble. It was super cheap. $175ish Only missing some of the extras, like the dimm.2 card and the front panel q connector.

The ram was from Memstore on ebay. And I ordered before I knew that B-die samsung was the golden stuff. So I have hynix A die, and it is so far OK. Not much overclocking yet to report on. 2x 16gb, will get another 16 to take advantage of quad channel soonish. Just didn’t want all sorts of money in ram if the motherboard was a dud. These are real weird. 4 chips on one side and 5 on the other.

The night I was able to finally put it all together, I was unable to get the two sticks to finish post when any of the slots between the cpu socket and the rear IO were populated. So in the interest of getting my new toy up and running, I populated two slots on the one side that worked.

Dread filled my mind. Was my motherboard broken? Would the memory slots between the cpu and rear IO ever work? I lived with my machine as it was for a week, as a half working machine is better than a not working machine. Plus, it was so fast and awesome, even if 4 cores didn’t have direct memory access.

Tonight I bit the bullet and took the heatsink off and reseated the CPU. As I tipped up the carrier tray slide, I saw a single hair in the socket between the pins and pads. (I am a hairy guy). I don’t know if the hair was the problem or not, but I know it wasn’t helping. After hair removal, and a reseating of the CPU, All the memory slots on both sides of the CPU work!

Just thought I would share. Reseat the CPU, it may solve some problems!

Alternative is to shave off all body hair before building


#3

That takes so long that the areas shaved in the start are grown back. Kind of like painting the Golden Gate Bridge is never finished.

I guess I have to get one of those clean room suits.

And after a reboot, I had to reseat the ram nearest the rear IO. And finally moved the stick from C1 to C2 (the very nearest slot to the CPU). Which according to the manual is not ideal. ARGGGGG

However, I am now at 2866 mhz stable (ish, not enough time to test fully). And previously 2800mhz would crash occasionally. Hoping for 2933!

Well thats progress-ish… as far as the hair causing an issue, probably not unless of course you have metallic glitter in your hair at which points all bets are off.

For all of the tales from tech I’ve heard

I’ve never heard of a hair breaker

Wish you would have taken a picture for the Tech Cringe Thread.

Eitherway, I had an issue the first time that I seated my 1920x and it wouldn’t play nice with the ram and wouldn’t post. Took out a few sticks and reseated the processor and it worked. repopulated the ram and it stopped working. Then it turned out that 1 of 4 of my sticks was bad. RMA’d the set, got a new set and it’s been working fine ever since. These threadripper processors are definitely finicky when it comes to seating them and tightening them down in those massive sockets.

Reseating everything a few times and using the process of elimination while troubleshooting these machines it definitely good advice. Thanks for sharing.
