9700k 5GHz (nybörjare)

Vad händer om man ändrar sync vore till per core och ställer en högre. Kommer du alla tugga på lika snabbt men när endast en används kommer den öka?

Shit. mitt moderkort är ett ASUS Strix och det överklockar automatiskt min 9700k.
Ligger på ca 1.6V idle och överklockar på 5.25Ghz.
Provad stresstesta med AIDA64 för att få upp tempen ordentligt (FPU-stresstest visar verkligen hur bra kylningen är), och efter 10 minuter så pendla tempen på ca 88-89 grader (det sker inte med spel iallfall, då tempen då ligger runt ca 70C tror jag), vattnets temp ökade med ca 3.5C under den tiden, och fortsatte öka (har väl inte ställt in fläkt-profilerna optimalt än, men sen vill jag ha lite tyst också).

Lite lustigt dock var att CPU-volten sjönk ned till en 1.51-152V under stresstestet, kanske CPU:n som temp-throttla då?

I idle ligger tempen på CPU:n ca 35C, vilket tjänst lite högt (GPU:n, 1080Ti, ligger strax över 20C grader just nu). Allt beror självklart också på den omgivande tempen också när det gäller idle misstänker jag.

Dock är väl mitt gamla CPU vattenblock lite dåligt tror jag, gjorde rent det, men tror jag vek några flänsar i blocket. Dock vet jag inte om det just nu är värt att investera i ett nytt block...

För övrigt använder jag glykol som kylmedel.

Edit: Effekten på CPU var ca 218W under testet också.

@Rico01 Tack!
Synd bara att den är på 1.6V. Har suttit och juxat med volten och satt den ned till 1.29V och gjort diverse inställningar enligt den här herren på youtube:

Mitt bios är lite annorlunda, men dom mesta inställningarna var applicerbara.

Förut hade jag ratio på 51x man satte ned den till 50x.
Så nu har jag 5.15Ghz och 1.24V enl. HWINFO (trots att jag satt satt volten på 1.29V).
Frågan hur man kollar om det är stabilt eller inte. Kanske man ska höja/sänka frekvensen eller volten, eller båda dera. Är inte världens bästa på det här.

Iallfall är CPU-tempen mindre nu, ca 32 grader på idle för närvarande.

Edit: Är väl på en ca 60C grader vid FPU stresstest nu med AIDA64, så kanske några grader till efter det då, låt oss säga 65C.
System har inte hängt sig än.

It's one of my favorite Youtube channels but one unmistakable problem of these guys is that they do not really play any game. Since they only benchmark games (in a very professional way) to make money, they do not have real experience in games, which means they sometimes neglect the fact that not only (i) temporal differences in FPS numbers in the same place in a game but also (ii) spatial differences in FPS numbers in a game matter from the perspective of a gamer. What I mean by this is as follows:

Up until a few years (2-3) ago, most games utilized DDR4/DDR3 memory only in order to load data when the player moves (or fast travels) to a new place in the game. Of course, those games accessed DDR4/DDR3 memory to regularly refresh the world / environments as the player moves around but, in most cases, the access to DDR4/DDR3 memory could be postponed a little bit to genereate high FPS numbers by accessing various kinds of cache (L1/L2/L3). In other words, DDR4/DDR3 was largely used to reduce loading times between different scenes. Recently, however, several open-world games seem to utilize DDR4/DDR3 memory very aggressively, so much so that, in densely NPC-populated areas or in very complex environments, they seem to heavily rely on DDR4/DDR3 memory to generate each frame because the amount of data that those games have to process for each frame is too huge to be stored in various kinds of cache (L1/L2/L3). I highly suspect that this trend will become even more pronounced in the future. Some representative examples are Assassin's Creed Origins/Odyssey, Watch Dogs 2, Shadow of the Tomb Raider, and Klei Entertainment's Oxygen Not Included (the last is not an open-world game but exploits a massive amount of data).

In terms of gaming performance, what does this mean? Due to the rarity of such densely NPC-populated areas and very complex environments, the average FPS numbers with two different DDR4 speeds are not so drastically different, just as shown in the above video. Even in these games, most areas are very sparsely populated. However, you can experience unexpectedly very low FPS numbers when the player moves to such aforementioned places. That is why lots of Assassin's Creed Origins players complain about the game's poor performance in huge cities like Memphis and Alexandria! In summary, if you can endure the ordeal of shockingly low FPS numbers on rare occassions (in those complex areas/cities), yes, I think 3200MHz is a sweet spot! However, if you are more interested in mitigating worst case scenarios (as well as increasing the overall FPS numbers), I would recommend you to buy higher speed DDR4 memory, for example, 3600MHz or higher. Just watch the following Youtube video to see what happens in populated areas:

(Watch from 40s)

Moreover, even with the forthcoming advent of DDR5 memory (maybe in 2020/2021), those memory modules will be rated for speeds not so much different from 3600MHz, which makes it unnecessary to upgrade your memory in coming years. Also, high speed DDR4 memory modules are nowadays priced very reasonably. Especially if you are using an Intel CPU (e.g., i7-9700K, i9-9900K), Intel CPUs are not dependent on memory timings whereas Ryzen CPUs are in fact notorious for their heavy reliance on DDR4 memory timings (due to the so-called Infinity Fabric). This means that, if you have an Intel CPU (which is free from problems arising from the chiplet design), you can buy high speed DDR4 memory with very loose timings. As a matter of fact, you can buy 3600MHz 16GB DDR4 modules for 1100-1200kr. They usually have CL19 timing but it does not affect the performance of an Intel CPU. As a digression, these memory modules are usually Hynix CJR die, so you can optimize timings by raising the voltage every so slightly if you "really" want to. In overall, for the elusive future proofness (which I gather that most people with highly specced PCs want to be assured of), it is probably more enonomical to invest in higher speed DDR4 memory modules.

Lastly but most importantly, I am looking for a used i7-9700K for my daughter's gaming PC. I know it's not a good idea to build a PC now but children do not wait... Please send me a PM if you are interested in selling your i7-9700K. If you have several PCs now, I think it is a sensible idea to sell it now to buy a mighty 12-core Ryzen CPU in July! I reckon that i7-9700K will be priced much worse after the release of that monster.
