@flanker I don't think that board has support for XOC

It's a shame that the Crosshair VIII Impact doesn't have any video out. Maybe the best motherboard for iGPU/memory overclocking with Raven Ridge is the B550 Phantom Gaming-ITX/ax? Hoping for XOC support. The X570 Aqua would be good in theory, but sounds overkill and 4dimm could hurt mem oc.

@Sladen Two things I'd try: Disabling cores Try a no-ucode bios

@SladenWhich bios are you using?

@4n0nym0u5b3nch3ri always bench my daily lmao might have bricked a few daily OS but never lost any data that I couldn't recover

@4n0nym0u5b3nch3r Do you think it would be possible to get 3466 cl12 working?

@4n0nym0u5b3nch3rkeep in mind kit to kit variance

@4n0nym0u5b3nch3r 3866 14-14 1.5vdimm with tight subtimings should work just fine I think, if your board/IMC can handle it

Any idea when this competition will take place?

Dang no Geekbench? Maybe I'm actually gonna have to learn something

Here are some resources for future competitors. Geek 3 Optimization: Memory relevant information: https://community.hwbot.org/forum/83-memory-heaven-airextreme/ OC Bioses and other overclocking-relevant information: https://community.hwbot.org/forum/119-skylakekaby-lakecoffee-lake-x-z170z270z370x299-oc/

Should be a whole lot easier for me to compete in this than OCWC 2020 lol Looking forward to the competition!

@gymleaderat that price just buy the ripped

@gymleader How similar are the prices? I know someone who binned like 50 kits of 3600c15 gskill and every single one was a2.

Has any tried 32m with this board? Would love to play the 4800c14 1t game but would prefer not dropping $400 on a board

*325XX consistent

@gymleader 4000 15-15 was also at 1.5v. I believe the Teamgroup ARGB available somewhere in Europe, and here in the US it goes out of stock pretty often. This was my first review, and there are definitely more tests that I want to run next time. Can you reply with the part number of that 1.4v rated kit?

This is not a review sample. Team Group 8Pack RIPPED Edition 2x8gb DDR4 PC4-28800C14 TDPPD416G3600HC14CDC01 https://www.overclockers.co.uk/team-group-8pack-ripped-edition-16gb-2x8gb-ddr4-pc4-28800c14-3600mhz-dual-channel-kit-black-my-001-8p.html Part 1 - Intro I only heard of this kit of ram because @sabishiihito posted about it on Facebook. At the time, it was priced at £139.99 including VAT, and ended up being about $175USD shipped to the US. That's maybe $10 cheaper than other 3600C14 bin kits including taxes, which sounds about right for a kit of RAM without RGB. My kit has a 10 layer A2 style PCB with Samsung B-Die ICs, and as far as I'm aware all kits of this bin do too. I am a fan of computer parts that don't have RGB, and this kit matches my setup very well. It comes with a nice short aluminum (?) heatspreader and shouldn't conflict with most CPU coolers, unlike the Teamgroup Xtreem DDR4 which is quite tall. Part 2 - Testing My setup includes an EVGA Z390 Dark (running on the first public XP supporting bios), delidded i7-8700k (running at 50 core/47 cache for daily and 50 core/50 cache for heavy OC), an NH-D9L, an EVGA GTX 980 Ti Classified, and an EVGA 750W N1. My air conditioning is set to about 20C but being summer I doubt it ever gets that low, even at night. 2A - XMP The kit is advertised as doing 3600mhz 14-15-15-15-35 between 1.4vdimm and 1.5vdimm. Interestingly, the XMP did not load the advertised timings. It set 3600 15-15-15-35 at 1.45vdimm. I don't know if others who purchased this kit have this problem, but I hope it will be fixed in a new revision. I have been notified that the XMP issue is likely motherboard related. No need to worry. Here is the performance at the default XMP: Thankfully, the memory would still run at the rated speed and timings just fine. I had to manually change cas latency in bios, but it's really not a huge issue in my opinion. See here: 2B - Manual daily overclocking My initial impressions of this kit for daily overclocking were quite good. It booted my base profile of 4000 15-16-16-28 280 1t tight subtimings with no difficulty and passed memtest without a fan on the memory. I then tightened to 15-15-15 and it still worked without issue. I then put a 140mm fan over the memory and tried for 4133c15. Unfortunately, these settings would not train at all. I backed off to 4100 and it trained without issue. I was able to get it to pass benchmarks at 4100c15 but it was not quite memtest stable. I then tried to do 4000 ratio x 102.1 bclk, and ended up with 4080 15-15-15-28 280 1t tight subtimings memtest stable at only 1.5vdimm! The performance is quite good, as you see here: This is slightly better than my previous best kit for daily overclocking, a pair of 4000c17 Trident Z Royal Silver that now belong to @Rauf. 2C - High voltage overclocking This kit made my work easy. It booted up my 4800c14 profile first attempt and within 10 minutes I had 4800 14-13-13-28 220 2t passing Geekbench 3 reliably at 2.05vdimm, without any vtt tuning. 4133 12-11-11-28 220 1t should be doable at the same voltage, however I did not test it. 4800c14 with more optimized timings needed 2.06vdimm: 32493 passed but crashed before the screenshot. tWRWR_dr/dd at 5/5 would likely push me past the 32500 barrier, but it needed more voltage. Like many B-Die made in 2020, the voltage tolerance is low. I could not pass SuperPi 32m at with or without waza at 4800 14-13-13 or 14-14-14 for that reason. These settings are not to be used daily. At such high voltages, memory access in Windows is limited to less than 2.5gb. Part 3 - Conclusion Overall, I'm pleased with this kit of RAM. It overclocked well beyond its rated speeds. It looks great and fits my system well. It's a great budget overclocking option, especially for people who don't have the money to buy a set that's been handpicked by a pro or or who don't have the means to go digging through the used market in search of a golden ticket. I hope the XMP issue is fixed soon, as more casual users may have a problem with it. I would like to see the Teamgroup Dark 3600c14 for sale in the US market. I hope the XMP issue is fixed soon, as more casual users may have a problem with it. I rate it an 8.5 9/10, definitely recommend.

Apparently, 4666 14-13 has been done with A0 memory on the Crosshair VIII Impact. Also, @sabishiihito almost got 4800c14 working on an Apex IX using an Apex X bios. Could somebody try to put the two together?

@unityofsaints can still use Benchmate 0.9.3

@keeph8n Z390 with 8700k and Windows 10 2004. @unityofsaints I tested it, I can confirm @Splave's findings with Windows versions.

In my testing, 3.1.5 is still slightly better than 3.4.3b3.

Rebench with 3.4.3b3 and chilly mem? Dual rank and/or c13?
