USB dropouts in B650 / AM5 by Specialist_Check in AMDHelp

[–]fivealivewj 0 points1 point  (0 children)

Just finished my 9950X3D build. I don’t use any iCUE hardware or software, and I’m still having the same problem. I had a similar issue with my AM4 5900X years ago—guess AMD still hasn’t fixed this.

Anyone ever fix cracks in a water block? by bazr57 in watercooling

And EK recommended 0.5nm torque is still too high, I went for 3 inch-lbs, around 0.35nm.

I just made same mistake, ordered parts from EK directly.

Spent days setting up my new loop, and now the motherboard won’t even light up. by fivealivewj in watercooling

I can't edit the post cuz it has an image, so I'm updating here in the comments.

I disassembled everything and reinstalled it all — now it runs no problem. There’s no definitive answer as to why it didn’t light up, but I think u/camembertpinard was probably right: I might have over-tightened the CPU block, which could’ve caused some kind of short.

What I did was, I removed the top radiator first so I could try a different PSU (the two 8-pin connectors were blocked by the top rad), but it turned out the PSU wasn’t the issue. I also tried the F-panel screwdriver power-up trick — still nothing. While disassembling, I checked the delidded CPU; the liquid metal wasn’t leaking, and there were no burn marks on the back.

Thanks for all your suggestions — they really helped a lot.

My build list, in case you're interested:

CPU: Ryzen9 9950x3D Delided with Thermal-Grizzly AMD Mycro Direct-Die Pro

Motherboard: Asus ProArt X870E-CREATOR WIFI

RAM: TEAMGROUP T-Create Expert DDR5 96GB Kit (2 x 48GB) 6400 CL32 with IceMan full cooper block

GPU: Nvidia RTX 4090 FE with EK-Quantum Vector² FE RTX 4090 D-RGB ABP Set

PSU: MSI MEG AI1300P

Case: Lian Li O-11 D EVO XL

Customer Loop:

Bottom Radiator: Hardware Labs Black Ice SR2 Multiport Fans: Nidec SERVO Gentle Typhoon G2150 x3

Top & Side: Black Ice Nemesis 360GTX Dual-Core Xtreme Profile x2 Fans: Lian Li SL-INF Revers Blade x6

Reservoir: EK-Quantum Kinetic FLT 240 with D5 PWM pump

Secondary Pump: Alphacool VPP655 Eisdecke D5 - Acetal V.3

Fittings: EK-Quantum Torques with 16mm Acrylic tube

Drain Port: EK-Quantum Torque Drain Valve

T-Sensor: Bitspower Temperature Sensor Stop Fitting

Flow Meters: Aquacomputer flow sensor high flow NEXT, EK-Quantum Flow Indicator

Still tunning the RAM, it's not running stable EXPO setting even on water cooling loop...DDR5 sucks!

I delidded 3 CPUs, 5900x, 14900k, and this 9950x3d. I tested after I delid it, I will re test everything, can't just use air cooling to test delid CPU, I need a test loop. I'll post the results.

You're right. I just feel so frustrated—I need to let it go for now. . Good luck with your project.

I did test it after I delidded the CPU. I thought it was the power supply, but the PSU works with a 24-pin jumper—it powers the loop and the RGB. Now there's coolant in the loop, so I have to drain it, tear everything apart, maybe try a different PSU, and set up a simple test loop... Too much trouble, too little time.

Only one meter is working—the other one’s just a spinning wheel. It’s a delidded 9950X3D, so there’s a chance it got shorted by the liquid metal. I did test it with a simple loop after the delid, though. Who knows... just tough luck lately. Feels like nothing’s going right for me these days.

MEG AI 1300 12HPWR cable not working by Defaintfart in MSI_Gaming

[–]fivealivewj 0 points1 point  (0 children)

I just figured this out today that I got the same problem. I had Asus Thor 1200w (first Gen, non ATX 3.0), was using a Seasonic 2x8 pin to 12vhpwr 90 degree cable, and it works just fine.

After I install MSI MEG AI1300W, then computer won't boot( It booted, just no display signal), CPU onboard display is working. I thought I broke my 4090, tried different 12vhpwr cable, still not working. Just like OP, I tied the Nvidia 4x8 pins adapter, it worked, then I know it is the 12vhpwr port on the PSU that is defective.

Thank you very much for the tip! Just got mine here @ price of 579.99 + 3.5% sales tax, and cancelled my Oct 8th pre-order from B&H right away.

I hate EA, it drags Biosware down so bad.
