Friend building new Ryzen 2950x system. DOA no matter what.

Have you inspected the socket for any bent pins?

 

Either hes installing the CPU wrong or he has a dud.

In all honesty after 3 boards I would review install procedures and call AMD and have them warranty the chip.

The chip MUST be installed in the plastic cartridge or else poof.

Edit...

I'll add in 20 years plus of building machines. And as a teenager in the mid 90s I worked in a shop and literally built my first 5 to 600 machines while in high school and was paid to do so. I've only seen one bad CPU and it was an old Celeron 300a.

So it's possible hes installing wrong or he won the bad lottery and got a dud chip. Happens.

 

This then

 

To the OP I recommend your friend watch the plethora of YouTube videos on how to properly install the CPU from opening the box to torquing the clamp down.

It will save him/her serious heart break.

Threadripper is unique in how its placed in the socket and locked down.

 

Quick one to rule future issue, is he observing proper ESD care ? Grounded wrist wrap, no paper / cardboard around the building area and ideally a ESD mat ? Also, low humidity make it worse.
Once that's in check, CPU is the last component not replaced so yeah as other pointed out...

 

That's a depressing result. Can't help but wonder what the issue was. 2950 > 9900

 

Hate to say this but this sounds like user error. The odds all these parts are bad? Basically 0.. Most common denominator in this is your friend, so I am just going with the odds here.

 

Your friend should just buy systems from people like puget systems and their ilk.

 

people claim there doing everything correctly but in reality they fucking shit up over stupid shit...as in there is no way all that stuff is bad. first tip is buying an asrock motherboard...anyone with good judgement would use exact same board kyle used

 

Hrmm

Yeah I would HIGHLY recommend he just buy a prebuilt. Please for the sake of sanity at this point Haha

Not down talking your buddy.

 

Yeah please let us know. If he watched the Video Kyle made on how to install a Threadripper CPU it covers everything.

 

I always dread these calls from my friend.

 

im curious if the merchants he sent the hardware back to for rma found a shit load of bent pins?

 

Sounds like my "tech" friend who couldn't get a crypto miner running.

He finally gave me parts and I gave him back a miner...... Which he promptly messed up while "tweaking"

 

It's easy to bend a pin, which is likely why it wont work.

 

CPU power plug is what comes to mind and often overlooked.

 

What is the flashing red light? Is it the Bios Flashback update light(right next to the CMOS battery)?

Assuming it's the bios flashback update light, he probably was attempting to install the wrong bios, although from what I've read the bios LED shouldn't flash red, it should either be solid green or solid red or off.

Now I'd go about this in stages and check if it booted after each one:

1. Many Ryzen Asrock boards have a bridge bios. That is, a bios that you need to update your board to, if it's on the original version, to then update to the latest version. The x399 fatality would need to be updated to Bios version 2.10 before it can be updated to the latest version of 3.50, for example. This would be crucial to make certain the 2950x functioned on the board, and if he's not updating the board correctly, it's unlikely to boot.

2. Make certain both CPU power connectors are connected. There are 2 on the board, a 4 pin and an 8 pin.

3. I would probably have removed & reinstalled the CMOS battery.


Other than a dead CPU/Socket, those are probably the only things that would straight up not allow the system to boot without a Dr. Debug error code. Would've included RAM, but even bad RAM would've come up with a Dr. Debug error code.

 

That 9900k working?

 

Wowsers.. he goes from 3 threadripper fails to full water cooling?

Sure that's wise? I'd hate to see a fitting leak and blow the 9900k. Isn't he being a little ambitious?

Not judging. Truly curious.

 

I’d bet a dollar he had most the WC for the threadripper and is waiting for a new intel block.

Sometimes people know just enough to be dangerous.
