thank you very much everyone, try 5 ghz first with 1,205 voltage and default ram memory without xmp and with 4300 mhz, in 2 cases BF5 in 15 minutes restart the computer ...

second operation I put cpu 5ghz with 1,215v and ram 4300mhz after 3h.30 restart of the computer ...

Now I am testing 5ghz 1,220v with ram 4300mhz I should not have problems but I will tell ..

I have the ram at 4300 cl17 18 37 350 with voltage 1,500
vccio 1,250
sa 1,250

those are the ram voltages that I use, is this checked with hci up to 1000%, do you see the high ram voltages?

 

Well, you're still doing all your testing with overclocked RAM by the looks of it, so that's different to what we suggested, but the fact that it is taking longer to crash with increased CPU voltage does make it appear that it's down to CPU instability rather than RAM instability. For your last test you've only raised the CPU voltage by 5mv - if that proves to be stable in BF V you might want to raise CPU voltage just by another 10mv to be sure that it's stable, it's good to have a bit of a buffer of voltage there, and also given that BF V shouldn't be the most taxing CPU load you can throw at it then you probably need that extra buffer of voltage to ensure stability in more taxing workloads too anyway.

Yes, 1.5V for your RAM, that is a high voltage, and it's the maximum that pretty much anyone will recommend as safe - most people say 1.4 or 1.45V as a safe max RAM voltage. I don't know if anyone here has personal experience of running their DDR4 RAM at 1.5V for a number of years - any tales of degredation or no ill effects? (I'm running 1.41V on my RAM with no ill effects for nearly 3yrs so far).

 

I have been running my DDR4 at 1.500V and higher for roughly 2 years and my personal opinion is 1.500V is as safe as 1.200V. I used to run my SO-DIMMs in Alienware laptops as high as 1.650V, and sometimes do that with my desktop when I am pushing the RAM as far as it is capable of being pushed. It just works better with more voltage, especially when you start running more aggressive timings. The RAM never gets warm to the touch no matter how much voltage it gets, and I haven't seen any changes. I think the whole push toward lower voltage RAM (starting with DDR3L) is just a thing that makes self-righteous tree-huggers feel like they have accomplished something special.

 

That's comforting to know that 1.5V is safe, assuming that all units respond the same way, although I imagine in a small ITX air starved case in a hot country the RAM could warm up more, and higher temps mean greater possibility of degredation through increased voltage. I know for my rig that I don't think I've seen any more than the high 40's for my RAM temperatures (maybe low 50's, can't quite remember), but I'd think twice about say 90 degC RAM and 1.5V. My RAM doesn't respond favourably above 1.4V, it actually becomes more unstable if I put 1.5V through it. I've got Dual Rank RAM, I learned (read) the other day that Dual Rank kits won't overclock well in terms of frequency, and that's exactly the same thing with my RAM - 3200Mhz I can run with really tight timings, and 3333Mhz is the max stable but at rubbish timings; benefit of Dual Rank is increased gaming performance, but a highly clocked and tight B-die kit at Single Rank would outperform it though.

 

Yes, high temperatures are really bad for all electronic components in terms of durability, performance and stability. The role of the increased voltage scales with frequency and timings, which makes perfect sense. If I run at lower clock speeds the higher voltage provides no benefits and seems buggy to me as well. But, that's OK because it's not needed at lower speeds. 4300 is really high. I suspect it would behave better with 1.450V to 1.500V at such a high frequency, especially if the timings are not left at their typically sloppy loose defaults.

 

knowing the volatge of the ram that 1.5v is sure that maximum volateg can be put in VCCIO and SA? that if, without degrading the cpu

 

Do not set 1.500V for VCCIO or SA, only for the memory. You will probably want those somewhere around 1.200V to 1.250V.

CPU input voltage can be set high, around 1.950V to 2.100V without harming the CPU.

 

and seen that on oc.net there are people who put 1.3v for vccio and sa ..

 

Yes, that's OK on the high end. Even 1.350V would likely be safe as long as the CPU is staying cool. But, setting 1.500V for SA might damage something. I've read you have to be more careful going too high on SA voltage. You should not need to set them higher than 1.250V, but you can check stability with 1.300V to see if it improves.

Not the facit, but you learn the bacic https://edgeup.asus.com/2017/kaby-lake-overclocking-guide/5/

 

Thank you very much for the guide, but I see with an HCI of 500% there is more than enough ...


Now I find out that BF5 uses AVX instructions ...

 

Yes, I think it does use AVX instructions, even BF1 does because I see my CPU voltage increase to levels that equate to AVX instructions seen in Prime95 or OCCT. That's another reason why I'm surprised that you can run OCCT stable but not BF V. Anyway, you're on the right track it looked like you just needed to increase your CPU voltage. Did you increase the CPU voltage, and to what value? Is it stable in BF V now?

 

If you have put AVX negative offset in bios you should see clocks will drop if AVX instructions is in use.

 

Very good to everyone and as always I appreciate your attention ^^ ...

5ghz 1,220vcore
ram 4000mhz cl16 17 36 1,4500v
VCCIO ,SA 1,180V

With this configuration I was playing 6 hours...
I don't like using avx

 

I don't know why you've lowered your RAM overclock and increased your CPU voltage - if you know which variable was creating the instability then you'd only be changing one of them, which is what we were trying to show you. Do what you like, but if it's stable that's the main thing.

 

AVX Instructions put higher stress on the processor. Roman at Caseking recommendation is -2 Avx negative offset

Almost 36K in Firestrike

 

and I decided to lower the frequency of the ram because I don't like the high voltages SA and VCCIO ... for 4300mhz I need sa vccio 1,250 ... and with the drop it goes up to 1,280

 

I think you got that the wrong way round, you just said for 4300Mhz you needed 1.250V for SA/VCCIO, and when you decreased to 4000Mhz you say you need 1.280V for SA/VCCIO. I think you got that the wrong way round. I'm not sure if you're trolling or not, but the vast majority of the time you defy logic and show inconsistencies in almost everything you post/say/do - so it feels like you're just bored/playing/seeing what people notice in the detail. I mean I know you have the language barrier, but that doesn't explain the inconsistencies, I doubt what you're about.

 

I'm sorry, I'm Spanish and donkey at the same time ... xd it will be for that ... haha what I say that for 4300mhz I need SA and VCCIO 1,250v but with the drop the VCCIO reaches 1,280 which means that I prefer to lower the frequency of the ram and lower voltages I never trolley anyone and FOX knows me ...

 

What 'drop'? If you're lowering your RAM overclock you don't need a higher SA & VCCIO voltage, what are you talking about? See, this is why I think you're trolling. I mean I know you supposedly put your PC together yourself and supposedly overclocked everything yourself, so you should possess at least a little bit of logic or consistency. A lot of what you say/post is 'circular', 'inconsistent', it feels intentionally so, it's not a language barrier - to be honest it feels like you're testing to see what people notice & what they don't, to see how 'stupid' people are. I know that sounds paranoid on my part (& inconsequential in the grand scheme of things), but really, you're not making much sense on many levels, and I'm trying to fit a picture to it.

 

I’m sure bro makina don’t trolling. Language barrier and with google translate on top can give some weird results.

 

Hopefully not, I just can't see the strands of logic though, it's a red flag to me. Maybe I've been playing too much BF1 and trying to see patterns in play to identify no-good hackers, it's made me paranoid and sensitive to unusual patterns! Ha, but it's weird, hardly come across many people here that post such "circular illogical inconsistencies". Like I mentioned briefly in my previous post, it's not really of any consequence either way - I just don't like to see people ignoring advice and being inconsistent & illogical at the same time, it feels like an insult or on purpose. Maybe it's the language barrier & google translate, I'll give it a rest. Sorry to Makina if I've got him wrong.

 

it's the translator's **** ... I don't fool anyone or lie ... all my ram OCs are checked with hci ... I don't like the ram at 4300 because I need too much voltage VCCIO SA ... that's why I lowered them to 4000cl16 ...

 

Bro, I agree with @Papusan I don't think he's trolling. He definitely knows a lot more than the "everyday" OC'er. I would say, whatever translator he's using, needs some work. I think @makina69 should add both English and Spanish (when he needs to go deeper into detail) explanations. It may help. With that said, I am with you. I seek out patterns in everything. It means you have a pretty high IQ.

I would to add, he's taunting me with that Gene. I really wish it came to the states with support. I won't import it because there is no warranty with it.

 

If you don’t understand English language completely and translate is your only option.., It’s difficult make understandable posts/answers.

 

but let it be clear that I don't trolley anyone

 

Yeah, now that makes more sense!

 

6h OCCT ´´´´´´´´5ghz 1,240v llc7 ram 4000cl16.......
the most important without mistakes of cache

 

Wow, 6hrs of stability on OCCT, that should be stable in anything I reckon! You got 67 degC max CPU temperature at 159W CPU Package Power, what cooling system are you using, and what's your room temperature? Have you delidded the CPU with liquid metal? (ah, I forgot, 9900K uses solder doesn't it, so no need to delid really).

I'm gonna blow the trumpet of air cooling for a minute, because most folks posting up here got water cooling, air cooling deserves it's rep too! This is my 6700K on OCCT with a peak of 123W, 60 degC max CPU temperature after 1hr testing, that's in 23 degC room temperature (see following screenshot). I reckon if I had a 9900K in my system here at your same 159W I reckon it would be about the same as the temperatures you've got there, especially as you've got the advantage of double the surface area on the chip to transfer the heat, so my results with my 6700K are handicapped by having a greater heat density in my testing. As you can see max fan speeds on CPU and case fans (all Noctua) is a low 900rpm, which is a gentle hum in the background. I'm looking forward to building my next system (next year probably) in this case along with this NH-D14 air cooler I have - I wanna see how it will handle an 8 core CPU!

 

tomorrow I put photos and computer explanation .... you have an excellent CPU ... small temperatures better ...

 

https://www.3dmark.com/3dm/39442295 Just over 36K now by disabling more Windows Services and Running CPU at 5.2GHz

 

https://www.3dmark.com/nr/163050 and https://www.3dmark.com/cg/4593923 was able to make top 100 into Hall Of Fame but couldnt seem to make it for Ice Storm Regular or Extreme nor could I make it for Firestrike Unfortunately.

 

The liquid refrigeration I use is simple:

https://www.ekwb.com/shop/ek-kit-p280

I only changed the radiator and put an Alphacool NexXxoS XT45 Full Copper - 420 mm radiator

 

That's a nice looking build, well done. That is a lot of CPU cooling you've got there with a 420mm radiator, pretty massive! I'm surprised that your CPU temperatures aren't a bit lower though, because you were at 67 degC for a 159W maximum CPU load. Like I mentioned and showed in my previous post I'm at 60 degC at 123W max load using my 'simple' Noctua NH-D14 air cooler, and that's with 4 core 6700K CPU that given my overclock has a higher heat density than your larger die 9900K (a variable that increases cooling difficulty). So, as a guesstimate, I reckon I'd be at the same temperatures with you if I were to wack your 9900K in my rig here. I showed my cooling results in my last post to blow the trumpet of air cooling, so that's why I wanted to compare it to your temperatures. What's your room temperature though, do you know? If you've got a very high room temperature then I can see that your water cooling setup is performing better than my air cooled setup.

I'll also add that my Noctua NH-D14 CPU cooler is using the Low Noise Adapter to lower the rpm of the fans to silent levels, and I know if I remove the Low Noise Adapter (if removed it's the stock condition) I get about 5 degC better cooling performance; I've also not blown out the dust from cooler for at least 6 months - so my CPU temperatures could be over 5 degC lower than the figures I've shown (I've just opted for a completely silent CPU cooling configuration). (My case fans aren't silent when my PC is under load though - gentle hum at load).

By the way, I'm not saying here that good air cooling is better than good water cooling, because that would be rubbish - when you compare the best of both then water cooling wins! What I am saying though is that good air cooling can be as good and sometimes better than water cooling, and that a lot of it depends on individual build factors such as PC case choice & mods, configuration of fans/layout, choice of thermal paste and it's accuracy of application/mating.

 

a simple computer, when it passed the test it would have almost 24 ambient degrees, but keep in mind that each cpu is a different world ...

 

We got about the same room temperature then, because I've got 23 degC room temperature and my idle CPU temperature reports 25 degC, and don't know if you're talking room temperature or CPU temperature there, but either way it makes our room temperatures to be about the same. Well, it does look like my Noctua NH-D14 in my setup is offering about the same cooling power as your water cooled setup there then. Yeah, there's factors in play such as your case and how you configure your radiator and fans, as well as the mating of the cooler to the CPU. With 420mm radiator water cooling I did expect lower temperatures from you though as that's a beefy setup, maybe there's some optimisation required somewhere along the lines in terms of case layout or fan configurations or how well the CPU cooler is attached to the CPU.

 

very good is very much 1,370v vccio and 1,408 sa are the voltages that the plate puts in car ... dangerous

AWESOME Fox xd

 

This is true. I bought it fully knowing of its limited serviceability and physical limitations, the most damning of which is BGA crap. Performance is good enough for what it is. I expect it to do a nice job of playing games, not overclocking.

Both have a shared feature that is also great: not a Dell/Alienware.

Part of the mission here is to provide additional evidence that anyone that spends more than what this small and mostly unknown brand costs is totally nuts because there is absolutely nothing to be gained by spending more for brand name BGA rubbish. This meets or exceeds what is available from other brands with the same specs, but the other options cost substantially more without offering any value to go along with the added cost. If fact, the build quality of this one is better than most of the like-spec'd alternatives.

 

I’m surprised your hands didn’t burst into flames when you touched the keyboard.

 

What's going on with the new laptop?! I know you said it's BGA in a later post. What kind is it, is it any good?

Not a bad Firestrike GPU score, just a little bit below my GTX 1070, so fine for games.

 

My brain almost did, LOL.

I still despise the idea of BGA filth. But, to be totally honest, there was no way on earth I was going to spend a lot of money on a laptop. The only option I actually "like" and would be super proud of is a P870. That is double what I paid for this and EOL. While this is a little more than what I wanted to spend, it's the best bang for the buck. It will do everything I need it to, and since what I want is super expensive, not in the budget, and EOL it was the only option that made good sense.

 

Well, it's as good as a BGA product can be. I haven't changed my opinion about BGA... still hate that. It has all of the negatives that accompany BGA, but not as pathetic as most and a much better value than anything else with the same specs. I didn't buy it for overclocking. I bought it for work/business travel and playing games on the road. It does that really well. I am using common sense here and staying within a budget, while minimizing compromise to the greatest extent possible due to limited options.

Eluktronics MECH-15 G2Rx (Tongfang whitebook sold by numerous vendors... Walmart Overpowered brand, HIDevolution, CyberpowerPC, XMG, PCSpecialists and others.) Metal lid and palmrest, mechanical keyboard with individually addressable (per key) RGB, very nice 144Hz IPS display and a decent assortment of ports. This is the one that @B0B and @OWNORDISOWN have done many reviews on for the past couple of generations of CPU and GPU advances. Forgiving the fact that it is BGA and focusing on it being what it is, this product is pretty impressive and offers a respectable value based on price.

I have always loved doing business with HIDevolution, and still do. Awesome folks. This was my first experience with Eluktronics and I have to say they are pretty awesome as well. My impressions are all very positive. They seem very responsive and passionate about their products and servicing their customers.

There is a 17-inch version that is also decent, but it has a plastic chassis. I opted for the 15-inch for the metal chassis. Would have otherwise preferred 17-inch.

 

Good review from Bob there! I can see why you bought that laptop, it was pretty solid in most areas, and the display looked like a real bonus (144Hz IPS, 98% sRGB), plus the metal chassis and brown mechanical switch keyboard - nice looking solid laptop. Do you know what the Eluktroboost function actually does, was it worth using? For gaming did you do an optimised tweak like Bob did? Ha, did you put liquid metal on it yet, or is that just gonna make your laptop less practical and less movable!?
