9900K or wait for KS?

Will try. I think I just quickly glanced at a review. What is your favorite program to stress it?
Click to expand...

I run the Intel stress test that's inside of XTU and I also run BOINC on all threads as well as try it with my favorite games. By doing all of those and it staying stable I consider that good enough.
 
my idea of stress testing is playing games for a few hours, because thats what my real world use will be. If it doesnt crash or behave abnornally I considered it passed.

I hate the idea of torture testing a CPU for hours at max temps just to see if its stable under those conditions.

The thing is though, it might be stable under some games and not others. If you can get it to pass some unrealistic torture test with a massive heat load, it will run like that under ANY real world condition.

How do you feel about Aida64 + Prime95 as a good OC stresser?

Prime was always quick to call me out on incorrect voltage and Aida64 spotted memory errors quick-fast..

Yes I understand if it is stable under the torture tests then it will be stable under any condition.

That's why I just play my games and if it is stable then I don't need to stuff around with ir, if it is not then I adjust the voltage/OC etc and continue gaming.

That way there is no need for me to put my poor chip under extreme heat for long periods.

You don't need excessively long stability testing. People will put systems under torture tests for 24 hours etc. but the fact is that's probably overkill. Anytime I've torture tested a system it's always crashed or locked up within the first hour or two. I can't recall ever seeing a machine run for 23 hours and then crapping out or anything like that.

I did the XTU test 2, 100% utilization at 5Ghz/4.7 uncore , 77C on the processor with 30C liquid. I went with 1.31V, 1.25V crashed under load. I’ll take it.

Pretty impressive it’s only around 140W on the processor. My 5960X took 400W to reach 4.8Ghz lol. Gotta love advancements.

So I am happy I went with the KF. Price seems right, performance is great, unless you want to wait a year (?) for 10-15% IPC (?).

I don’t see myself needing higher IPC or core count anytime soon.

Good deal. At least you got that voltage down. I love my 9900KF for my gaming rig. Can't beat it.
 
I read I think on Gizmodo that when the KS hits the market the 9900K/KF/KS are going to all get a considerable price reduction. Do you think that's reliable info?

Possibly. As it is the 9900KF can be had for as little as $419.99. I don't anticipate them dropping much below that, but I suppose its possible. Intel has done drastic price cuts in the past when its needed to.
 
I've had stability tests fail past the 10 hour mark. I do try for at least a 12 hour full test before putting a pc into service, I keep my machines for a few years so it's worth the extra few hours or day to ensure it's stable moving forward.

There seems to be some weird scaling wall for most games past 5.0 ghz.
At 720p ultra, most games saw no performance improvement:
https://www.techpowerup.com/review/intel-core-i9-9900ks/13.html

1080p medium, which is probably more CPU intensive, showed little change as well.

130 fps is seems high, but remember, this is a 2080ti running 1080p medium.

The 9900k is geared towards hardcore gamers. The 9900ks is geared towards benchmark gurus and crazy people.

Interesting. Maybe something to do with u-arch? Maybe ring bus doesn't clock up with core frequency? I have no idea how it is linked internally or if it's separate like HT/IF etc.
So we could be seeing the limits of feeding those cores.. bit like Vega core overclocking being not 1:1 either.. memory limitations... this is similar behavior.

I'm not sure why they are running medium settings. That's leveraging the GPU more than running it on low. Honestly, that's likely why there is no real change past 5.0GHz. Next, 1080P isn't going to be more CPU intensive, if anything it will be slightly less so than a lower resolution. The more you increase the resolution and the more visual effects you apply the more your leveraging the GPU.
 
I currently have a 9900k and I like it but im also under a custom water loop and mainly game. The 9900ks is just a better bin for others that want that assurance kinda like what the did with the 8086k
 
My 9900KS is currently at 5.2GHz/1.30v - too high? I tried 1.275v and I got a BSOD.

Temps are great - maxing out at 74C (during Intel XTU) using an H115i AIO.

EDIT: lol up to 1.35v and prime95 still kills it. XTU passes. Raised VCCIN to 1.25.
EDIT2: looks like this CPU is already binned for 5GHz so beyond 5.1GHz you need more luck. I couldn't get true stability at 5.2GHz (went up to 1.35v). Just not worth it when I play online MMORPGs like ARK and it can royally fuck my game up lol.

OK. I couldn't imagine anyone buying a 9900K today. It would make sense to get a 9900KS or go a step down to 9700K if it's a dollars issue. "Big" is relative when you're talking about top dog gaming performance. Even the 8700K could hang with the 9900K in most gaming workloads.

Beyond all of that - AMD is the best overall choice today. Further making the 9900K irrelevant.
 
Can I plug a 9900K or 9900KS into a Z390 Asus ROG Maximus XI Hero motherboard, and it'll work okay? I think my delidded 8086K is starting to show problems, I used high voltage to get 5GHz. That or my day one 2080Ti is fizzling out, which is a real possibility.

I am stumped why my sig says Z370. Maybe the product on the vendor's page changed. What about Z370? I'll have to check what's in my PC, hah. First step is to downclock to 4.5 and see if the problem remains.

Yes K and KS will work fine in those boards. Your VRM's will be a bit toasty but it will work. Make sure you update to a recent BIOS first.
 
The Microcenter in Dallas has a ton of 9900KS processors in the display case.

It says 6 in stock. I am guessing they will all be sold by year end (nationwide). 6 took a few days at my MN location.
 
My MC in Maryland is jam packed with Intel CPUs in general. Site shows 10+ 9900k/ks in stock each.
 
9900KS is in kind of confidential production, just to look good as to "we can make those things" to investors.

I don't think investors have much to do with it. The 9900KS is all about Intel trying to hold onto the one thing it has going for it and that's gaming performance.

That would mean there needs to be plenty of them and this is not going to be the case. I'd rather believe they tested plenty of them for months to have some exceptional ones they provided to the media and started marketing the little amount they had on well known places promising for higher volumes that will never happen.
I was believing in the recent lies of Intel going forward with 10nm and new batch of Ice Lake CPU but not anymore. It looks like they weren't even close. Intel has no plan to make anything better for the 2 years to come before they get on 7nm if they can, but I'm already unsure of that. It also seems that despite they hired some old professionals with reputation, who may have retired otherwise, people are starting to quit Intel. It looks like Intel could go bankrupt in a couple of years if they don't find miraculously a solution. My best bet is they should swallow their pride, buy TSMC or Samsung full technology for a huge amount of money (tens of billions $) and maybe offer them all their optane et flash in exchange, because the US military and administration needs US made chips. This needs to happen now. Would solve most of their problems.

No, it doesn't. How many of those CPU's they have is irrelevant. Obviously, Intel has production issues across the stack for anything beyond 4c/8t. The further away from that number it gets, the worse things are. However, the CPU and all other designs are about Intel holding onto as much of the market as it can. Either through the product itself, market perception or whatever.

What you'd rather believe is irrelevant. We will never know how long it took for Intel to hand pick enough KS's to turn them into a variant of the 9900K and get them on shelves. They aren't rare at this point. I see plenty of them on shelves.

This is almost certainly false. Do not confuse "can't" with "no plans to." Intel may very well have no designs that are ready to move forward if it has a way to produce them. At this point, all Intel's troubles relate to its production processes.

Charlie has a mixed reputation. He's been way off on things before. I'm not saying he's wrong, I don't know that, but the name of the site is "semi-accurate" and that's not unfounded. I would have a hard time believing Intel would go bankrupt in a couple years. I mean, look at AMD. It found a way to operate for decades while making no money. Big corporations can certainly fail, but I don't believe the time frame.
 
Intel going out of business? I got chu fam, investor funds sent!
