Resolution Does Matter

[TiSA88]

I don't understand why people say that lowering the resolution put stress on the cpu when it's just the opposite, playing just cause 3 in 1440p my 5820K is in 30-50% load and 20-35% at 1080p
Not to mention i see some of the threads hitting 70 to 80%
I have v-sync on (60 fps locked) on my 980 Ti

By the way the game stutter sometimes
Frame drops on those big explosions.

Who says this as people know a higher resolution requires a beefier system?

I don't understand why people say that lowering the resolution put stress on the cpu when it's just the opposite, playing just cause 3 in 1440p my 5820K is in 30-50% load and 15-28% at 1080p
Not to mention i see some of the threads hitting 70 to 80%
I have v-sync on (60 fps locked) on my 980 Ti

People generally say that lowering the resolution puts more stress on the cpu because the lower the resolution, the less work the gpu has to do. However, I said "generally" because this can vary a LOT depending on what game or games you are playing. Some games are much more CPU intensive than others and so it really depends on what game as to whether it's more CPU or GPU bound. That's why a lot of the review websites use so many different games to judge performance.

It sounds like Just Cause 3 isn't greatly optimized for multiple threads. Does your game stutter at both resolutions? 1440p and 1080p? Since you have plenty of CPU cores, you might try running a program to check the GPU load to see if it is hitting 100%. Also, is your 5820k overclocked or at stock? Do you have trouble with any other games or just this one?

Because it generally does.

cpu has to prepare each frame, rendering at certain resolution is purely on the gpu, lowering res means more frames per second, so the cpu has to prepare more per second, increasing load.

If you're running capped vsync there shouldn't be any change in load though, unless the game changes lod and viewdistances with resolution too (which some do).

I've seen many people saying that 1440p/4k bottlenecks the GPU but that's not the case with just cause 3.
Gpu usage is around 60% with v-sync on.
Will do further testing.

I will test both resolutions to see if that solves the stuttering, rise of the tomb raider was the last one I played and didn't had stuttering but the game dropped to 55fps at one point.
My 5820k is at stock, i would like to oc but I don't think my nh-d15s can handle that.

Was this a joke...?

If so it's in poor taste. The NH-D15 should happily handle a 5820k at ~4.2GHz, if not higher depending on your specific CPU.

I have had mine at 4.7GHz stable using moderate water cooling. The 5820k is one of the most underclocked CPUs intel sells. Even with the stock cooler you can hit ~3.8GHz

Do i have a faulty cpu?
I changed the ram speed to 3000mhz (125 bclk) In the past and that increased the voltage and the heat so I downgraded to 2400mhz (100 bclk)

My D15S has only one fan and the windows 10 was crashing with that blue screen when i had it running on 125bclk strap (29x 125)
i had to reset.. don't know if that's a problem with the motherboard or the cpu.

You dont have to bclk OC with these CPUs

Just up the multiplier and make sure you have enough voltage.

I have 100bclk 43 multiplier and 1.28v

Never get temps over 72-73C.

Yeah but i have a kingston hiperx predator 16gb ddr4 3ghz, i have to run it on 2.4ghz?

It should have an XMP profile. Just set the XMP and make sure your memory voltage is set appropriately. On my particular board i'm running 3200MHz RAM. I just had to set the XMP, then manually set my CPU S/A voltage because for some reason my motherboard left it at stock. But once I did that it was fine.

The CPU has an integrated memory controller. No need to OC the bclk for OCing your RAM either.

All i did was change the XMP profile to 3000mhz and it did all the rest, it increased the voltage of the cpu to 1.2v, the ram to 1.35v and the multiplier to 29x 125
It wasn't a manual oc, the motherboard did the job.

A few months later i had crashing so i reset the system and manually oc the ram to 2400mhz (can't go higher than that otherwise it would increase the bclk to 125)

Then it's your motherboard specifically doing this.

With full manual settings you should have no problem setting everything normally.

I had heard of some of the older X99 boards automatically changing the bclk with higher speed RAM, but that was usually because the x99 platform had memory stability issues at first and I haven't personally seen it happen.

These issues should have been fixed with BIOS updates. So I would recommend making sure you've got the latest BIOS from your motherboard manufacturer, as there may be improved memory stability.

as you can see here, 99.98 bclk and a 43 multiplier.

I heard people saying you should never update the bios because is dangerous, is there any risk?

My motherboard personally has a dual BIOS so you can just flip a switch to a backup BIOS if you somehow mess up the update.

However, i haven't had any issues in the 3 times I have updated my X99 BIOS. Obviously its going to depend on the board, but if you're having issues OCing and getting your memory stable at the speeds you want, then i'd say it's worth a shot. Up to you however.

I need to replace one of my DIMMs at the moment but i've been lazy and I dont NEED the extra bandwidth at the moment.

It's less about stressing the cpu and more about ensuring the gpu isn't the limiting factor.

By dropping the resolution you are ensuring your benchmark results are not fill rate limited, for example if a 980ti can only achieve 30fps at 4k then trying to bench multiple cpu's at that speed will result in a graph that largely shows only minor variations of 30fps.

Drop it to 800x600 and you are likely to see the cpu's ability to process scene setup become the limiting factor as the gpu can literally spit it out as fast as the cpu can set it up and your results graph will be far more diverse and reflect the cpu's ability to handle the math in a best case scenario.

I've updated the bios and now i can push the XMP profile to 2666mhz at 100bclk
3000mhz is not possible

It used to be substantially riskier when the possibility of actually pushing a corrupt file into the eeprom was higher (the 90s).

Most all update tools will verify the integrity of the update before flashing it these days and the worst case scenario is simply a refusal to apply said update.

Provided you are using the manufacturer's update tool and manufacturer's bios the likelihood of a catastrophic failure is extremely low.

However it is inherently safer to flash bios using a bootdisk style tool as Windows based tools are still susceptible to system crashes during the physical flashing procedure which will end badly for your mb assuming it does not have a backup bios. Which it likely does.

A sudden loss of power during the physical flashing stage will also result in a brick, but you would have to offend all the gods to actually be this unlucky.

Sorry if all this is obvious but the benefits of bios updates, especially motherboards far outweigh the associated risks, which in this day and age are quite low.

*Edit- Aaaand you already updated 20mins before that rant. Oh well it at least provides some context to the mythical bios update risk I suppose.

Lol.. ive updated using a flash drive in the UEFI

I read the HardOCP review on your particular motherboard and the reviwer notes that anything over 2666Mhz on that particular board defaults to 125bclk, the reviewer laments this saying on the higher end Asus boards this issue was fixed and they allow fine tuning with 100bclk and he wished it was fixed on this board, but it was still an issue.


So looks like it's just an Asus thing with their lower end X99 boards. Not sure if by oversight, or specifically to encourage sale of their more expensive boards, but either way it sucks for your case.

What the hell, this is so unfair!!
I threw money away on this expensive ram then
