Need some advice for a new VR gaming PC...

[15[Span.]/JG51Navarro]

Hi all,

I´m thinking on purchase a new PC for gaming focused on VR and I am not used to OC and hopping not to update it anytime soon...

Here are the components:

 

CPU: Intel Core i7-8700K 3.7Ghz
MB: Gigabyte Z370 AORUS Gaming 7 or Gaming 7-OP

GPU: GIGABYTE GeForce GTX 1080 Ti AORUS W.FORCE W XE 11GB or Gigabyte AORUS Geforce GTX 1080 Ti Gaming 11GB GDDR5X

RAM: Corsair Vengeance LPX DDR4 3000 PC-24000 2x8GB CL15 (enough frecuency or need it higher?)
SSD: Samsung 970 Evo PCI-E NVMe M.2 500GB
HDD: Seagate Barracuda 2 TB 7200 RPM
PSU: Corsair RM750X V2 750W 80 Plus Modular or RM750i 750W 80 Plus Gold Modular
COOLER: Corsair Hydro Series H150i Pro (if yes, which one) or Cooler Master MasterAir Maker 8
CASE: NZXT H700

 

What do you think?

 

Thanks in advance

Looks pretty good to me.

 

I will be doing a new build here soon, have been using a Corsair H100i on my current build ( almost 5 years old) and have been really pleased with it. I will go with another one (whichever is the more updated one) for my new build also.

 

[15[Span.]/JG51Navarro]

dburne, thanks for your fast reply. You will go to the Corsair H100i v2, which looks good to me, or to a higher series one?

Have not really looked into it closely yet, but likely I guess the H100i v2.

Hey, if you search the forum there's another recent thread (within a week) where someone is asking the same question. You'll find detailed stuff in there, but looking at your config:

• RAM is not fast enough for IL2. Get 3600 if you can, and CAS-14 if you can. I got 3200 CAS-16 and I regret it, it's just not fast enough.
• IL-2 is CPU bound for VR so anything you can do to improve single-threaded AVX performance is a must. Definitely get a 240/280mm liquid cooler. Consider the 8086k or even waiting for the 9000-series chips which will be clocked higher.
• Motherboard needs to be good for overclocking. I don't know exactly about the one you're looking at -- maybe check a few reviews and see how they did with overclocking on that board. For my build I went with a 10-phase power delivery on the motherboard, for better CPU overclocking.
• NVMe HDD doesn't do anything over an SSD for gaming. If you're working with a fixed budget, consider a 'regular' SSD and putting the money into either an 8086k or faster RAM or better CPU cooling.

Here's the other thread I mentioned, more info in here:

Think it all depents on what generation VR he wants to buy, if it is a gen1 OR, Vive or Samsung Odessey then I geuss this will be OK. But if this is the gen2 VR like the Pimax 5&8k or who knows StarVR, I would wait for the 2080ti, it will be available when these gen2 VR is in the webstore. 

Same about the new Intel CPU and Z390 motherboards.

Make sure to overclock; it's necessary for good VR performance and there's generally no reason to avoid it. Many easy guides are available for popular overclocking motherboards. 

 

The RAM isn't terrible, but I agree that you should get something faster. Overall, it's a rather sketchy time to be getting an epic gaming rig with 9th gen CPUs around the corner. 

[A_radek]

Agree with those saying wait. If the 9-series really has the rumored Oc potential due to a soldered Ihs they could be well worth it. A cpu that get’s close to 6 ghz would be a rather large step considering the last generations and something we could use right now with the first gen hmd’s. For the pimax, as things are looking, I don’t see any alternative. 
 

If the Oc potential of the 9 series proves to be just hype and speculation, the 8 series cpu’s will by then be available as nicely discounted cpu/motherboard combos.

Hi guys, thanks for your comments and help!

 

Alonzo, thank you very much for your recommendations.

 

After I have read your comments on the other thread I've changed some components of my previous configuration, here are new ones:

 

CPU: i7-8086K Extreme OC 5.2Ghz Delid (5.3Ghz gets way out of my pocket)

RAM: Corsair Vengeance RGB Pro White 16GB (2x8) 3600Mhz CL (CAS) 15 - highest frecuency-lowest Iatency I can find but I have read that low CAS does not have to be a must for gaming, true? 

 

According to this https://wccftech.com/intel-z370-motherboard-roundup-asus-msi-asrock-aorus-gigabyte/ the MB Gigabyte AORUS Z370 Gaming 7-OP has 10 phase power delivering. So MB remains the same. 

 

I like the Corsair Hydro Series H110i 280mm but I am open to suggestions... 

 

I do not really understand what you want to say with: "NVMe HDD doesn't do anything over an SSD for gaming." Sorry for my poor English.

 

Mitthrawnuruodo, SvAF/F16_radek, I do not have a PC right now, it's dead!! ? and I don´t know if I want/can wait until the 9-series generation comes out, who knows how long it takes...

 

Thanks in advance

 

Regards,

Hey, 6GHz is a lot. I don´t expect to reach that number in an steady way with a good liquid cooling. I think 5.3 or even 5.4 GHz is more aligned with my expectations.

From where did you get that? Silicon Lottery?

5.2 is a very good freq.

[A_radek]

To be honest I don't know where I pulled that number from,  probably some speculation in the internetwebz as I all by myself would never salt a post here to make a point ?. Your right though, 5.4 sounds like a high enough expectation.

Here in Spain there is a PC Gaming online shop selling it, coolmod.com (coming from Spain maybe you will know them).  They offer also the 4.0Ghz, 5.0Ghz, 5.1Ghz, and 5.3Ghz but I will double check it before to proceed with the purchase.

[15[Span.]/JG51Navarro]

I also like the Cooler Master MasterLiquid 240... aesthetically I like it more than the Corsair but performance come first.

I'd say don't bother and get a nice monitor.

Corsair is a good cooler, check Gamers Nexus for very in-depth cooler testing. 

 

NVMe is a fast drive, but it's only faster than 'regular' SSD on very large sequential file transfers. I would just get a non-NVMe m.2 drive, they are quite a bit cheaper than the NVMe drives. You still want m.2 interface, just save the money and don't get NVMe (unless money is not important, in which case have fun and NVMe is fun!).

Yeah! I knew this online shop but I didn´t know they were selling delidded&OC CPU with warranty. Thanks!

Where I work we have to buy PCs 3 or 4 times per year, for applications which are also very much dependent on single-thread.  We were buying from pccomponentes.com or from Mantis.es or other. But it is good to know that coolmod go beyond them.

Let´s see if they also overclock the new 9th gen.

[15[Span.]/JG51Navarro]

chiliwili69, I didn`t knew either. I have find it out making a budget for the new gaming PC (the prices are very similar to those of PcComponentes). I didn`t knew they delid&OC the CPUs either. Do you know by any chance if the people from PcComponentes delid&OC the CPUs too?

Do you have already bought something form coolmod, are they serious sellers? I have read good and bad things about them...

PC componentes doesn´t delid neither OC.

I have never bought at Coolmod. I have no opinion. Sorry.

My PC is generally spec'ed the same way as yours (i7 8700k + 1080ti, ssd, etc) and one thing I can really attest to far as the efficacy is RAM speed and latency. I've had DDR4 3200 CAS 16 memory for the past year. Then after reading Alonzo's comments I went out a bought me a DDR4 3200 CAS14 memory.

 

Man, after the swap it feels that I got 15-20 fps during some heavy loaded scenarios near the ground, with smoke, 10+ players, etc. Soo..  3200 CAS14 RAM is definitely something you'd want to take a look at.

I have seen that the highest CPU that currently sells PcComponentes is the i7-8086k 4Ghz.

Ok, no problem, thanks anyway.

delidding is pretty easy actually. I did the delid/liquidmetal/relid mod on my 8700k and it couldn't have been easier. The only requirement is to get the delidding kit, which is a special tool that allows you to remove the heat cover from the top of the CPU. After that it's just basic clean up of the gunk from the previously used glue, applying a layer of liquid metal from a syringe to the top of the actual cpu chip (it's shiny), then attaching the heat cover back with some super glue. The full load CPU temperature drops from ~85 to ~60C using a liquid AIO cooler (2 fan).

Here in Spain I am able to find either 3200Mhz CAS 14 or 3600Mhz CAS 16, which one should I choose from the two?

so here's the rational behind these numbers:

 

- The frequency is expressed in Hertz, which means "cycles per second". So, the DDR4 3200 will perform 3200 cycles a second or 3600 cycles per second for second memory type.

- The CAS latency is given in cycles. So, a CAS14 RAM will take 14 cycles to respond and the CAS16 obviously 16 cycles.

 

- so the formula is:

for 3200mhz cas14:     14/3200=0.004375 seconds latency

for 3600mhz cas16:     16/3600=0.004444 seconds latency

 

?    I'd go with 3200 cas14 simply because of math.. ?

Thank you very much, now I understand how it works!!

I'll go with 3200Mhz CAS 14 too! ?

I can get the following 3200Mhz CAS 14 RAM: G.Skill TridentZ and FlareX Black. Any recommendation...

What do you think about the ASUS ROG Maximus X Hero, Code, and Formula Series mother boards?

Those are good overclocking boards that appear in places such as Silicon Lottery's Qualified Vendor List. 

 

Both the memory listings should be good as well.

 

 

[Alonzo]

The 3200/CAS-14 and 3600/CAS-16 are both similar in performance, I'd get the one that's cheaper. If you can find 3600/CAS-15 that would be marginally quicker. Some people also do stuff like take 3200/CAS-14 and then try to tighten the timings. I've had no luck but there might be memory kits out there that tighten nicely.

I tried to find 3600mhz cas 15 but had no success... :/

 

If I take 3200 cas 14 OC to 3466:    14/3466=0,004039

3200 cas 14 OC to 3600:                   14/3600=0,003888

3200 cas 14 OC to 3866:                   14/3866=0,003621

 

3600 cas 16 OC to 3866:                    16/3866=0,004138

3600 cas 16 OC to 4000:                    16/4000=0,004000

 

It seems that if you OC the 3200 you get a faster response than the 3600 one but I don't know if it's possible to reach all the parameters described above (sorry for my lack of knowledge.)

Overclocking certainly isn't guaranteed. I think you should go with 3200 CAS-14. That's good memory already, and if you are able to push it a little higher to 3333 or 3466, that's a nice  bonus.
