Can I get thoughts on this build before purchasing? RTX 4090 | i9 13900KS

[A Computer Guy]

OMG , so confused .. in that case , isn't 4 sticks of DOMINATOR® PLATINUM RGB 32GB (2x16GB) DDR5 DRAM 6600MHz C32
better than 2 sticks of DOMINATOR® PLATINUM RGB 64GB (2x32GB) DDR5 DRAM 6000MHz C40

can anyone please post some links to the best RAMS 64GB RAMS I can have for this setup? on ASUS Z790 Hero? Preferably CORSAIR RAM PLEASE!

I'm only finding CORSAIR 64GB KITS that are 6000 C40 !!

You may have to consider the classical compromise in speed vs. capacity depending on what is more important to your use case.

According to the QVL these are the fastest Corsair 64GB RAM kit that has been verified working with your motherboard:

CMT64GX5M2X5600C40(Ver5.43.13)
CMT64GX5M2B5600C40(Ver5.43.13)
CMT64GX5M2B5600C40(Ver.5.43.13)

It's DDR5 5600.

There's also a lot of faster 64GB G.Skill kits on there as well, for example:

F5-7000J3646G32GX2-TZ5RS
F5-7000J3646G32GX2-TZ5RK
F5-6800J3445G32GX2-TZ5RS
F5-6800J3445G32GX2-TZ5RK
F5-6400J3239G32GX2-TZ5RS
F5-6400J3239G32GX2-TZ5RK
F5-6400J3239G32GX2-TZ5RS
F5-6400J3239G32GX2-TZ5RK
F5-6000J3040G32GX2-RS5W
F5-6000J3040G32GX2-RS5K
F5-6000J3040G32GX2-TZ5K
F5-6000J3040G32GX2-TZ5RK
F5-6000J3040G32GX2-TZ5RS

You can see the frequency right after the first - in the model names above.

All of the above kits have been tested working on this motherboard with their included XMP profiles. That said, some of the higher frequency kits may vary based on IMC quality (7000 and 6800). 100% safe bets would be the Corsair kits listed above or the G.Skill kits listed above at 6400 and below.

Corsair isn't risking high returns. This is why you aren't seeing above 6000 MT/s. What doesn't make sense about not getting the same frequency with 64GB vs 32GB? Unless you need 64GB, don't buy it. Dual-rank manual doesn't clock as high, doesn't have the lowest timings (retail) and costs a lot more.

Remember just because it boots into windows, does not mean it stable

Ok, let me just get my head around this,

4 sticks of DOMINATOR® PLATINUM RGB 32GB (2x16GB) DDR5 DRAM 6600MHz
OR
2 sticks of DOMINATOR® PLATINUM RGB 64GB (2x32GB) DDR5 DRAM 6000MHz C40

will ONLY the 32GB DOMINATOR® PLATINUM RGB 32GB (2x16GB) DDR5 DRAM 6600MHz be enough if I'm overclocking? Or will 64GB give more benefit in OC?

 

[64K]

You obviously have a very large budget. The only thing I would change is to get a larger SSD. With some games requiring well over 200 GB storage space and games only get larger and larger over time.

Just think of 4x16 and 2x32 will have similar oc. Regardless if you have 4x 16 or 2x 32. The CPU sees 4 ranks of memory. That is the biggest limiting factor. Second is 4 slots. That comes with some other hurtles related to the motherboard and how it handles 2 DIMM on the same channel, but different traces.

You can do more with 2x32GB from a OC standpoint, but that requires some tinkering.

Plug n play XMP route will more or less being the same. Anywhere from 5600-6400. Just depends on the MB auto voltages and the quality of the CPU IMC.

Only reason to get 64GB is you need it. You said earlier your not going to try and overclock, so which is it? Realistically that 6600 memory kit is not going above 7000 MT. Soft limits of Hynix M Die for us normals. You want higher either but a higher kit or pump some abusive amount of voltage in.

I meant not over clocking the MEMORY , but I AM OCing the CPU !!!

"Realistically that 6600 memory kit is not going above 7000 MT." Can you clarify that part? don't get it , my motherboard supports up to DDR5 7800, so if I get this one https://www.corsair.com/us/en/Categ...-RGB-DDR5-Memory---Black/p/CMT32GX5M2X7600C36 you mean that it won't actually run at 7800 ??

So what I'm really asking is , if I go 32GB instead of 64 GB ... will this

DOMINATOR® PLATINUM RGB 32GB (2x16GB) DDR5 DRAM 7600MHz C36​

give me a good overclock on the CPU , as if I was using 64 GB? or will the 32GB lower my CPU OC capabilities ?

 

[64K]

32 GB RAM is plenty for a gaming PC. 64 GB would just be a waste of money.

 

[ir_cow]

Sorry @MoeNAGY , Someone else will have to take over on memory advice. I think I answered the 64GB question already.

You are likely to get a much larger boost out of running faster memory vs trying to OC a CPU that is already at it's thermal limits even if you are able to get an extra 200mhz ST out of it in gaming workloads pairing it with 64GB of ram you will have to run much slower than 32GB will likely negate any gains you are likely to get. At the end of the day its your hard earned cash but with a 4090 at 1440p in the majority of games you will be very CPU limited running faster memory is likely going to be much more beneficial in more scenarios vs having more of it.

 

[15th Warlock]

Hi, I'm in process of shopping for a new gaming PC across famous PC configurators. What do you guys think to the following list?

CASE: CORSAIR ICUE 7000X RGB SERIES ATX Full-Tower Gaming Chassis + 4x CORSAIR SP140 RGB ELITE fans
CPU: Intel® Core™ Processor i9-13900KS 8P/16 + 16E 3.00GHz [Turbo 6.0GHz] 36MB Cache LGA1700 [Special Edition]
COOLER: CORSAIR iCUE H170i ELITE 420mm with LCD Display Liquid CPU Cooler System & Copper Cold Plate
SSD: 1TB SAMSUNG 980 PRO (PCIe Gen4) NVMe M.2 SSD - Seq R/W: Up to 7000/5000 MB/s, Rnd R/W up to 1000/1000k (Single Drive)
MEMORY: 64GB (16GBx4) DDR5/5600MHz Dual Channel Memory [+60] (CORSAIR DOMINATOR PLATINUM RGB)
MOTHERBOARD: ASUS ROG MAXIMUS Z790 HERO DDR5 ATX w/ Wi-Fi 6E, 2.5GbT LAN, (2)PCIe x16,(1)PCIe x4, (5)M.2, (6)SATA
OS: Windows 11 Home
POWERSUPPLY: 1200 Watts - Thermaltake Toughpower Grand RGB 1200W 80 PLUS Platinum w/ Ultra Quiet Smart Zero Fan Power Supply
MOINITOR: LG UltraGear QHD 27-Inch Gaming Monitor 27GL850-B, Nano IPS 1ms (GtG) with HDR 10 Compatibility and NVIDIA G-SYNC, 144Hz,

** I plan to add more NVMe SSDs at a later point.

Specific questions:

• I know many won't advice for overclocking the 13th Gen 13900KS, however, if I'm an overclocking freak and I plan to do it, will the ASUS ROG MAXIMUS Z790 HERO be good for it?
• Is the power supply valid for this setup?
• I originally planned to have this built in COOLER MASTER HAF 700 EVO case instead of the CORSAIR ICUE 7000X RGB, but heard that the COOLERMASTER RGB software is not all that, and I also wanted to keep everything unified for RGB software, case , cooler , RAM. Is the CORSAIR ICUE 7000X a good choice for this build?
• With the H170i ELITE with LCD, the fans max RPM is 1600. Where as the non LCD version fans go up to 2000RPM. Is this a big factor to consider for cooling?

Got the 13900KF, running at 6.2GHz, save yourself a good chunk of money and skip the KS version, totally not worth it.

 

[Hyderz]

how many kidneys, blood plasma do you require for such a setup?

 

[gffermari]

For OC fun the KS will be great. Obviously it will be slower than the new X3Ds but that’s different story.

-the 990 pro is the latest name from Samsung. Take at least 2TB.

I don't think the KS will overclock much, the point is kind of that it already comes overclocked from the factory. As for the X3Ds being faster, time will tell. I wasn't impressed. The KS at least has that thing going that it's going to be the fastest-ever DDR4 compatible CPU, so that's my reasoning behind trying to acquire one.

Bit of a weird flex by the OP (they seem new to PCs altogether and buying extreme gear from a boutique is the worst mistake you can ever do), but I wish them a grand build

No, absolutely not. These are marketing blerbs, claims extrapolated from something that is likely to be lab controlled XOC, done with hand-picked CPU, hand-picked memory chips, at a very low temperature by an expert overclocker with intimate knowledge of subtimings and electrical characteristics of the platform and semiconductors involved.

I strongly recommend you reconsider spending thousands of dollars on extreme hardware, especially if this is your first build (and it seems to be). Things like ultra high speed memory are intended specifically for people who know what they are doing, so the chances that you are just setting yourself up for a fall (or at least wasting thousands on things you cannot extract the full potential of) are very high, especially considering you're buying at a PC boutique and not building it yourself.

If you want to claim to have an amazing next-gen gaming PC, buy the i9-13900K (or the KF/KS, suit yourself), a 32 GB kit rated at 5600 to 6000 MHz (timings don't matter much unless you're chasing scores, I don't recommend spending much extra on a C28 kit instead of a C32 for example), and any RTX 4090 you may want, the FE is a solid pick if you can buy one.

As for the motherboard buy a simpler motherboard - you visibly do not need a ROG Maximus. The power supply you mentioned in the OP is alright.

 

[Chrispy_]

This build is going to be very fast and insanely expensive.

I feel like @Dr. Dro has the best advice here which is tone down the build slightly. There's a lot of money being spent on the CPU/RAM/motherboard/AIO and unless you are a veteran overclocker who knows exactly why you want them, they're probably not going to be of any value to you. They exist as halo products with the highest price tags to rake in fat profits from people who have more money than experience.

A more mainstream Z790 Strix, A regular i9-13900K, or even an i7-13700K would do (the extra E-cores of the 13900K are completely useless for gaming), and a more mainstream DDR5-6000 RAM kit like the Corsair Vengeance RGB would be a better starting place. There's a lot to learn with overclocking and to get the most out of forums/reddit/discord/guides on the web, you'll want hardware that lots of other people own. The people with knowledge and experience to share tend not to buy the rip-off halo/flagship stuff (because they have the knowledge and experience to know they're being ripped-off), so if you're looking for memory timing advice or motherboard BIOS tweaking help from the community, you won't have as much luck with ultra-premium hardware that almost nobody else owns.

Buy the best/fastest mainstream hardware you can, experiment and ask for advice on the commonly-used hardware that many others in the wider community have experience with and then - since you'll have a fat wad of cash saved from not buying ridiculous halo products, and a whole bunch more experience with the platform, upgrade whatever is holding you back later.

 

[Vya Domus]

That CPU is going to be a serious waste of money unless you get faster memory, as in the fastest memory you can reasonably get.

Planning on buying one, but I will be using it with my existing DDR4 kit. If I manage to get it, hopefully soonish, I'll definitely make a thread sharing my experience.

Case in point:

Halo chips such as these are never, ever worth it from a price/performance standpoint, they are eccentric products for eccentric folks

Two sticks is always better for overclocking than four.
Four will reduce your maximum OC speed.

Same goes with memory slots, for OC two beats four.

you would reach the same speeds with a normal 13900K with that cooler. (the KS only makes sense if you run LN2)
and with the saved money you could buy faster ram and have a overall faster system (6000 CL30 for example)

 

[lightning70]

I think instead of buying an Intel system right now, wait for the new ryzen 7000 x3d series.
Even if you cool the 13900KS with 420mm AIO, it will reach 100 degrees. I don't think it will surpass 7950x3d in the game, no matter how high the clock speed it has.

Almost all AIOs are weak anyway. If you're going to spend big bucks on an AIO with it's unexciting little block and anaemic integrated pump, you might as well do it properly and get a custom loop powered by a real pump. The CPU-only components of my Alphacool loop were similar in price to the H170i Elite and obviously the pump/block performance are in a different league to AIOs, but I also understand that OP's choice of the H170i was probably because of the RGBLED and integrated screen.

** Please note, my knowledge with memory is very limited, hope I can back simplified answers!

Hi all, I'm getting a new build soon and I'm going with i9 13900KS on it with RTX 4090 on ASUS ROG MAXIMUS Z790 HERO DDR5.

I know, many won't advice with overclocking the 13900KS but what if I want to be an overclocking freak and do it ?? I'd aim to try to overclock the CPU ONLY, not overclocking RAM at all beyond enabling XMP.

My question here is what RAM capacity / frequency should I be using the the 13900KS? My motherboard is advertised to support up to 7800mhz.

• Does 64GB result in better CPU clocking over 32GB ?
• Why are people advising me to use only 2 sticks of RAM? So, if I wanted to use 4X16GB 7200MHz C34 module listed above for 64GB, what's the downside to that?

1. No, RAM capacity has no effect on CPU OCing, all else being equal.
2. It's a bit easier on CPU memory controller/Motherboard to run only two sticks of RAM. Running 4 sticks could result in lower RAM frequencies being required for stability. But that all depends on the specific RAM/motherboard/CPU configuration.

 

[ir_cow]

Why are people advising me to use only 2 sticks of RAM? So, if I wanted to use 4X16GB 7200MHz C34 module listed above for 64GB, what's the downside to that?

As explained previously, its very unlikely to work with either 2x32GB or 4x16GB at 7200. Especially since you want a plug n play experience. The only way I can see that configuration working is if you like to manually set voltages and tweaking DRAM settings. Seems a bit outside your realm.

My motherboard is advertised to support up to 7800mhz.

"Up to" is the key words here. Just because the motherboard is "validated" to those speeds, does not mean the CPU can do it as well. Also side note, that's for 2 DIMMs only. A little trick ALL motherboard vendors do.
