Strix Z-790-E Gaming/13900KS Combo, 14900KF (2), TG Mycro DD, Supercool DD

[Mr. Fox]

After selling both of my Z790 Apex boards, CPUs and associated parts, I am getting around to offering up the surplus parts. As I found better binned CPUs to buy, I set aside some of the great samples as backup/spares rather than selling them right away. Now I have leftovers that are still better than average. I forgot I had these hoarded away, LOL. So, I had to purchase a motherboard to confirm their identities and test them. So, now I have a new motherboard to sell that was only used to check these CPUs. I've also got a couple of bare die blocks I no longer need.

 

All CPUs were delidded for bare die application. They have been relidded with liquid metal for resale. All tested and found to be excellent. The IHS can easily be removed for direct die application if desired. There is only one drop of rubberized glue on each side to hold the IHS on the CPU.

 

Payment: PayPal Friends & Family or Zelle cash transfer

Shipping: Buyer Pays (or local pickup)

 

Send a PM if you are interested. No more testing or benchmarks will be performed, so don't ask.

Item #1: Z790 Motherboard/13900KS CPU Combo - $550 + Shipping - SOLD - NO LONGER AVAILABLE -

The motherboard is essentially brand new. It sells for about $350-400 depending on where you look and when. I do not know how high it can be tuned stable. I tested an AMD EXPO 8000 kit in it and it booted up fine but needed more tuning to be daily driver stable at 8000. The CPU is mounted with a Thermalright frame and will ship in the motherboard (as currently installed). The stock ILM and socket cover is in the box.

Updated 5/27/2025: 

Well, the mobo and CPU combo deal just got sweeter. I had an old G.SKILL Trident Z5 7200 kit that had one bad stick. It was in my spare parts pile an forgotten about. I rediscovered it going through my stuff to sell and I had it replaced under warranty and today received the brand new replacement kit. I am including it in this mobo/CPU bundle at no extra cost. So, it is like getting $135 for free with the purchase. It sells for that price on Amazon today.

G.SKILL Trident Z5 RGB Series (Intel XMP 3.0) DDR5 RAM 32GB (2x16GB) 7200MT/s CL34-45-45-115 1.40V - Metallic Silver (F5-7200J3445G16GX2-TZ5RS)

I just now opened the sealed package to install it and set the XMP profile to confirm it was good. No tuning done, just confirming the kit runs at the rated XMP speed and timings.

Buy with confidence everyone. 

 

The 3090Ti, 10850K, z490-h and 16GB 4400Mhz DDR4 RAM all purchased from @Mr. Fox all were in great condition and still working in tip-top form.

 

If I had even the slightest justification, I'd be PM'ing instead of posting lol

Item #4: Thermal Grizzly Intel Mycro Direct Die V1 (non-RGB) - $50 + Shipping <<This item has sold - no longer available

[Clamibot]

I'd buy one of these if I hadn't already bought a 14900KF from you last November. That thing is awesome.

Bro Fox is an awesome seller. You can buy with confidence from him as you will get exactly what you paid for. He will also make sure you get what you paid for. As a result, I scavenge used hardware from him like a vulture when something is available.

Thanks brother. 

 

Somebody needs to grab that dirt cheap CPU/mobo combo before I change my mind about selling it. 

[Mr. Fox]

I haven't change the price on overclock.net but I am willing to knock $50 off the mobo and CPU combo for members of this forum. So, $500 + shipping. The motherboard is basically brand new. It was purchased for the sole purpose of identifying each CPU (SP ratings) because I had lost track.

[Mr. Fox]

SP104 CPU - Lapped Copper IHS

Only item remaining is the 14900KF (SP104). Everything else has sold. @YoungChris at oc.net is interested but having to scrape up the cash. It's not being held for him. First-come, first-serve.

 

I've got a WireView and WireView Pro that I am not able to use any longer. I sold the Gigabyte 4090 that one was used on and the other one will not fit my 4090 Suprim with the new Alphacool Core waterblock. (It did fit with the Byksi block.) I will probably list both of them and the MSI 4090 Byski block. If anyone is interested before I list them drop me a PM to let me know.

[Mr. Fox]

All items sold now.
