Mr. Fox

They used the space to the right of the DIMM slots for a vertical NVMe slot and heatsink, which I am totally fine with. I like that a lot, same as DIMM.2 and the NVMe slot on the B850MPOWER next to the memory. But, it is goofy that they put just enough distance between the slots to make the Supercool block not work. The Apex has wider spacing than most as well, and the IceMan block is too narrow for the Apex. So, the Elite Duo X has even more space than the Apex. You don't notice it until you try to screw the block onto the DIMM jackets. You have to bend the modules toward one another to get the screws in, so that is not cool. I initially installed it and got to looking closer and did not feel comfortable with the visible amount of distortion. I tried using thicker thermal pads on right DIMM to shift the cold plate toward the left memory slot to balance it out and relieve the tension, but that was not enough to get them straight enough for me to feel comfortable with the installation being "safe" for the memory slots. (That thermal pad trick works fine on the Apex to use an IceMan block because the space is not as great. It's only about 0.75-1.0mm wider than normal spacing on the Apex.) Things would be better if all of the OEMs held to a standard on this.

I have had people (some not even noobs) argue with me and say things like "no, that's not the problem because my RAM is only reaching 65-70°C" and they often don't believe me that anything above about 40-45°C is "too hot" and will cause errors.

When Gigabyte scores a win it is usually pretty solid and respectable. They often do not, and they are masters of cheapness and engineering shortcuts. They are an example of a company (there are many) that doesn't learn from its mistakes. The X870E AORUS Master was a phenomenal motherboard and I mostly loved it. The firmware had some minor but glaring functionality omissions that they didn't care about. The one that I hated most was no ability to disable onboard WiFi and BT modules. For people that use them, not a big deal. For people like me that do not, being able to disable them is super important. I don't want crap that I don't use enabled and I deserve having the ability to disable it. Like many companies, they only care about what normies care about so they can sell them products and if you're not a normie you get to have whatever the normies are willing to put up with. Guess what? The Elite Duo X has no BIOS option to disable WiFi/BT. But, I can disable the wired ethernet device if I use WiFi. Bastards.

I am returning the Gigabyte Z890 AORUS Elite Duo X. It arrived today after a 5-day slow ride from Amazon in Baltimore and I have spent about 8 or 9 hours fighting it. Super nice motherboard, but something is bugged with the hardware or the firmware. When I first installed it, could not get it to POST normally with two RAM sticks. It would POST, restart and then hang with the DRAM debug LED illuminated. So, I swapped in another memory kit. Same thing. Cleared CMOS several times and nothing. I then got it to boot with one RAM stick, but Windows would freeze while loading. I tried to reflash the BIOS using the EZ-Flash button after renaming the BIOS file GIGABYTE.bin but the button would not do anything. Totally unresponsive. I finally got into the BIOS and the file was seen as "invalid ROM" by the BIOS. I moved the memory stick to the other slot and tried again, then it worked and I flashed the BIOS. After that it booted with both RAM sticks. Both memory kits booted fine. I turned it off, unplugged it, then plugged it in again. This time the EZ-Flash button worked and it seemed all good. Easily hit 8800 stable. I thought "OK, that was weird, but everything is fine now." NOT! I began working on tuning the CPU, but any change made to the D2D clock ratio other than leaving it set to "Auto" it would only boot to BIOS Safe Mode with the message that the BIOS settings were unstable. Another issue I encountered, even though it is a 2-DIMM board, the memory slots are spaced several millimeters further apart than the Apex and the Supercool direct touch RAM block would not work with it. I considered getting an ASROCK Taichi OCF, but don't really like the brand or how it looks. (I have hated all three ASROCK mobos I have owned in the past.) Ordered another Z890 Apex for $25 less than the OCF. It was $100 more than the Duo X, but I don't need any more drama. It will be worth the extra to keep my sanity. No more likely to drip on the GPU than the CPU block. I've never had a memory water block that leaked before. This story made the thought of getting the Taichi OCF an even more unattractive option. That, plus the fact that I have never actually cared for any ASROCK motherboard previously, including a Z370 Taichi and X870E Taichi.

OK... The decapitation was painless and the thermal improvement was even greater than my other 270K Plus (which was about 15°C). Using the same BIOS settings, more than 20°C cooler in Cinebench R23 versus stock solder and IHS. The IPC uplift with 270K Plus over 14th Gen Intel and AMD's finest is pretty insane. (Captured in the CPU-Z benchmark.)

I learned a lot about Ryzen by chasing overclocked benchmark scores. It is goofy in some ways compared to Intel. The same in other ways. Principles are the same. Clock is king and clocks need more voltage. Ryzen starts losing performance when it is voltage starved. It clock stretches but performs worse, maybe starts dropping IPC. TM5 (as well as Karhu and perhaps other tests) is also going to error out if your Curve Optimizer undervolt is too aggressive. Don't automatically blame it on the memory or a weak IMC. I'd recommend setting Curve Optimizer offsets to 0 when checking for memory stability, if all tests pass and you set your previous Curve Optimizer offsets and start having errors, you know immediately what needs to be addressed and it's not the memory overclock. You can use the SMU debug tool to test PBO CO offsets with Core Cycler in Windows, then apply the settings in the BIOS once you find the max stable negative offset. Best to do it per core. There can be a gigantic difference between cores. Perhaps contrary to popular belief, a core that can handle a deeper negative offset is not necessarily a good one. When I look at per core SP ratings and V/F curves, the better cores are already needing less voltage and the crappier cores need a deeper negative offset to match the voltage needs of the better cores.

The pleasure is mutual, brother. I am super excited for you and I can hardly wait for you to get the stuff in your hands. Having everything under water is going to be a real game-changer. I think my next purchase may need to be a block for the 5080 Prime if I can find one that isn't absurdly overpriced. I do not like anything being air cooled if I can avoid it and GPUs put off a ton of heat into a chassis.

Sold my 9950X and Mycro Pro to @damric on overclock.net. Now I have the B850MPOWER on standby for Zen 6 if that turns out nice. It's rocking the 4585PX for the meanwhile, along with the crappy V-Color dual rank turd RAM. I am so glad I snagged this 8400 memory kit and Supercool block on overclock.net back in March for $450 just to have on hand in my spare parts. It will pair well with the 270K Plus in the Z890 AORUS Elite Duo X. If you can even find it for sale it's a fortune. Super stupid - selling for $1500 on NewEgg now, LOL.

I ordered this as my second Z890 board. Price for a 2-DIMM is hard to beat. This is a LONG review and he actually does live memory overclocking and does a teardown on the board.

Sold to our beloved friend @Reciever

Sold to Brother @Reciever. A pleasure as always, friend. Thank you.

It never ceases to amaze me how much better temperatures are bare die.

I believe Brother @Papusan does Yeah, I sent the tools back already. Hopefully @Jor3lBR won't mind letting me borrow them again. If I sell the Apex components I will need to buy another Mycro Pro block as well. If that happens I may buy a GIGABYTE Z890 AORUS Elite Duo X to replace it and see how that fares. Looks like a good 2-DIMM option without having to pay an Apex tax to avoid having a 4-DIMM mess. It looks like Z890M (mATX) options with 2-DIMMs and a debug LED are essentially non-existent, which is very unfortunate. A memory cooling kit will definitely help. Even the legacy type with generic heatsinks and a waterblock bolted on top is a huge improvement and not that far behind a direct touch RAM block.

No worries, brother. Putting the needs and concerns of your family first and the ability to provide for them takes precedent over anything else and you are making a good/right choice in doing that. I would be disappointed if you allowed any kind of hobby or fetish to draw your attention away from that duty. I only offered it in case you were interested and able. Since you are a friend I wanted you to have first crack at the stuff based on our recent communications about the CPU and memory overclocking experience you have had with it. If your main use of the PC for pleasure is gaming there is no point in returning what you have or buying a 270K Plus CPU and Z890 mobo. AM5 is going to live quite a few more generations and what you have right now is way more than adequate for a world-class gaming experience. Superior overclocking capabilities using the highest end parts (like those you already have) is not of any remarkable value in the context of gaming. It would only be worthwhile for eking a little bit more life from an antiquated setup or marginally adequate hardware that stuggles with gaming workloads.

These parts are currently in my daily driver build. I may regret selling, but I could use the cash to fund another project. I am not "parting out" at this point, (so don't bother asking,) but willing to sell it all as a bundle. I really like this build and I am not desperate to sell, but asking a fair price on these super expensive components. Here is what is included: X870E Apex motherboard (includes box and all original accessories) 9950X3D2 CPU - Delidded (will include IHS and retail box) Buyer's Choice of: Thermal Grizzly IHS, Thermal Grizzly Mycro Pro DD block, or IceMan DD block G.SKILL Trident Z5 Neo 6000 C26 (2x16GB) Memory F5-8400J4052G24G 1.450V Supercool Computer Direct Touch Memory Cooler (will include stock RAM heatsinks) If you do not want a 9950X3D2 CPU for some reason, I have a decent 9950X that is delidded and also runs 8200 stable with tight timings and I will discount the price to reflect the cheaper CPU. (We can discuss that via PM.) Price: Asking $1800 including shipping and insurance to a US buyer in the lower 48. SOLD Item Location: San Tan Valley, AZ Shipping: As noted above. International Shipping: I will consider selling internationally but buyer will pay all costs associated with shipping outside the lower 48 states unless a shipping forwarding service is used (with a US address).
