[SOLVED] i9 10900Kf, RTX3080, RoG Maximus XII Formula.....which RAM kit?!

[TravisPNW]

Anyway, if the performance gap is minimal between 3600 and 4000MHz (I understood it is), I doubt MSFS2020 will gain anything different.
Or maybe I'm missing something, there? =o

The reviews I read including the one here said MSFS2020 benefits from the fastest ram possible... so that's what I went with. The fact they even mentioned it in the review got me to thinking.... why not? Even if it's only 1-2% faster as I said already it was literally a $30 difference between 64GB 3600 and 4000... so I went with the 4000.

I'm one of those guys that puts value at the top... hence the ram choice... and CPU choice. I only considered 3600 and 4000 and the price difference really made it a no brainer. Same for the CPU.

It's true that the "silicon lottery" is a thing, when overclocking, but I believe 5.3GHz is perfectly within the capabilities of any i9 10900K. Unless you won the lottery of the opposite, and you got the worst possible, that is.

The issue with the temperatures becomes a thing when you pressure the CPU with Prime95 tests, and even then I doubt a good 360 AIO liquid cooling system wouldn't be able to handle the heat and avoid the down-throttling.

At least, this is what I've read around the Internet, by browsing through several overclocking articles featuring stability tests.
By all means feel free to correct any possible misconception.

You're pretty much spot on. I've had mine at 5.3 but temps were a bit much for my 360mm AIO... pushing 90C. Running it at 5.2 is 80-85C on stress tests so that's where I run it. Every day temps are much lower. I also run a -2 AVX offset. When using apps like Handbrake the difference between 5.2ghz and 5ghz when encoding 2 hour videos is literally 2-3 minutes... and temps are lower.

Either way, I'm happy with how I did with the silicon lottery.

A 5.1ghz all core i9 10900k is worth 800$..

Dunno why that guy talks about how much of an AMD fanboy I am. I actually perfer intel, and am super pumped for 11th gen, but AMD is just better right now, no contest aside from the low end, where AMD doesn't have a zen 3 cpu.

Value is a contest Intel wins hands down... at least in the USA.

My 10900k/3090 PC benchmarks in the top 1% on 3Dmark... and that would be the upper half of the top 1%. I say that because I've seen a lot of PCs that scored 3000-4000 pts lower than mine and were also in the top 1%. Links are in my sig... all for a $500 CPU... and got 79th in Unigen's Superposition 4K optimized. What would I have gained by getting a 5950x for $1300 from a scalper? Something like a 0.5% improvement and a few extra fps that you and I both would never notice?

Yeah, that sounds totally worth an extra $800. Anyway, I rest my case.

Anyway, this discussion is done.
Thread closed.

Good idea.

Good idea.

"Value at the top"
Just.. what? I said that there is a small upgrade from 3600 and 4000, it's a bit better, you need to decide for yourself if the upgrade is worth your money, Never said it was no upgrade at all.

Literally exact same thing I said for the clocks.

"A 5.1ghz all core i9 10900k is worth 800$.."
I should rephrase this:
It costs 800$, it's not worth that much.

3Dmark is a good benchmark for comparing 2 systems, but it is not a good benchmark to see how much better a system is.
Why are you again comparing the 5950X to a 10900K? they are not in the same class.
Also, the 5950X is much faster than the 10900k, not .5%.
6 more cores, and a real world single core improvement of about 15-20%.
https://www.guru3d.com/articles-pages/amd-ryzen-9-5900x-and-5950x-review,10.html

But again.. you shouldn't compare these 2 chips...
What is the price of a 5800X in the USA? that is the chip that is most closely resembles the 10900k is multicore performance (since it has 2 less cores, but faster overall cores)
If it is more in line with pricing, then it's really a tie in price-performance with those same scalper prices.
But again, in MSRP USA, and in most other places in the world, the pricing is higher than MSRP, but still same ratio, making ryzen 5000 more value.

Just.. what?

I really don't care man... All your babbling lost credibility with me when you made the comment about the most a 10900k can overclock is 5.1.... Value and availability are contests Intel wins hands down... at least in the USA. It doesn't matter how good AMD is when it's not in stock.

... and the .5% comment was in relation to the top 1%.... am I gonna see this 15-20% improvement WHEN I'M ALREADY IN THE UPPER 1%? Am I gonna notice it? Am I gonna get $800 worth of improvement? Hell to the no and that brings us back to my point... VALUE.

Now I'm done debating when you. Go buy yourself an AMD system so you can actually own the product you are quite obviously in love with.

Anyway, this discussion is done.

Take your own advice. I'm out and won't be responding further.

[....] I also run a -2 AVX offset. [....]

I've read what AVX instructions are, but I have no idea how/why to tweak anything related to them.
How does it work, why that value, and how should I choose which value to set?

Ok... I'll reply to you.

You can change the AVX offset in the BIOS settings. Your CPU will downclock when running those instructions. Mine is at -2... (200mhz) so my 5200mhz OC drops to 5000mhz while running AVX... like in Handbrake.

As I said, the result is lower temperatures while not really affecting performance all that much. My encodes take 2-3 mins longer but the CPU runs at a lower temp. AVX is brutal on a CPU.

More info here.... good luck.

[SOLVED] - why do folks set an offset for AVX when OCing?

every guide i've seen suggest setting AVX offset at -2 or -3 when OCing. I know that will drop the OC by the same value when the CPU encounters workloads requiring AVX instruction sets, but why do we want that offset?

Thank you for the link, it was enlightening!!
So, say, if you stepped back by 2, having a 5.2GHz overclock, would you say I don't need that with my 5GHz?

It really just depends on what temps you are getting. If you're running hot set an offset. Mine was encoding at 85C or so on all cores, so I added the offset and now it's 70-80C on all cores... at the cost of only 2-3 additional minutes of encoding time.

Easy tradeoff.
