A messy kitchen, 9900K UK edition, 85F but chilly inside

Put the 8700k into the new gigabyte z390 Aorus ultra board Lastnight and so far it is not doing nearly as well as the Z370 Asus board for vCore required. When the 8700k was in the hero x it only required 1.275v to run 4.9ghz stable in prime 95. I stopped at 1.30v Lastnight after it blue screened again. So much for the current gigabyte boards being more stable with better VRMs. There’s no reason for this much voltage to run 4.9 on this chip. This is the 3rd gigabyte board in a row in the past 3 years that I have had these issues with. If it won’t stable out soon then it is getting pulled out and returned for another Asus board. I told myself 3 years ago after the 2nd gigabyte board fiasco that I would never buy another board from them again...

 

 

Have you updated the BIOS to the latest? It can make a big difference you know. This is a new platform, so there will be bugs to address. I've come across this with so many builds over the years. You may find with a few BIOS updates that you are stable at a lower voltage.

Voltage is never accurate in the BIOS. You need a multi-meter attached to the board to read voltage accurately. My 8700K in a Maximus X Code, required 1.34 or so for 5 GHz on all cores, 1.4 for 5.2 GHz with HT off. 

Were there any other parameters you may have set that would affect the voltage. 

You are also comparing an 8700K in a board it was originally designed for, a Z370, with an 8700K in a Z390 that is a "compatible" board. Two different chipsets involved, two different platforms. So variables at play.

Yeah at first with the stock bios I was having very weird avx throttling even though it was set to 0 in the bios. Massive bug that would have caused me to return the board when it first came out. The latest bios fixed that problem though. I’ll mess with it tonight and find out what voltage it needs but the fact that it is already much higher than the Asus is cause for concern. Temps so far are under control at mid 70s in prime so I have some legroom still at least considering this pc is using an h80igt cooler and not a 360 like my 9900k.

I don’t think this board will give me 5ghz because the voltage delta on the Asus board between 4.9 and 5 was massive. It ran 4.9 avx offset 0 stable at 1.275v and needed 1.365v for 5ghz avx offset 1. I never could get 0 avx offset at 5ghz all the way up to 1.4v when temps became too high. If this board won’t do 4.9 at less than 1.32v then it is going back and gigabyte is forever on my motherboard ban list with no option to return. Great luck with their video cards but their motherboards for me have been unstable messes.

If anyone is interested, I've ordered another 16GB (same model 2X8) of G.Skill 4400Mhz RAM ... why you may ask.  Good question, I was actually able to make P3D V4.4 use more than 16GB of RAM, 16.3GB to be exact ... with the following:

Orbx NorCal
Orbx Vector
Default Maule
AS4 + REX SF3D 2048/4096 cloud textures
ChasePlane (clipping adjustments in camera.cfg to stop z-fighting)
UTLive
TEXTURE_SIZE_EXP=10  (PR hi res 1024 terrain adjustment)
OPAQUE_SHADOW_TEXTURE_SIZE=8192
TRANSLUCENT_SHADOW_TEXTURE_SIZE=2048
OPAQUE_SHADOW_DRAW_DISTANCE=8000
MAX_TEXTURE_REQUEST_DISTANCE=320000.0000
MaintainSystemCopyOfDeviceTextures=0
ENABLE_MEMORY_OPTIMIZATION=0

SCENERY_DRAW_DISTANCE=64000.000000 ... could have gone ot 128000.000000 which would have consumed more memory

All other graphics settings were maxed out.

When I started paging to my M.2 things got a little slow, so slow the audio even started to stutter.  Had I been using a more complex aircraft like PMDG or FSL I think I would have been well in 17GB RAM usage ... so the moral of this story, 32GB of RAM is in order if one is going to push the P3D V4.4 envelope beyond "normal" UI configurations.

Cheers, Rob.

Hi Rob,

I am indeed very interested to hear your thoughts after receiving your 16Gb.
I've recently purchased another 2x8 Gb after reaching the same conclusions as yours using the FSLabs A319 on complex scenarios and heavy weather conditions.

I was a bit anxious to add more heat to the system filling in the 4 RAM slots.
Actually it doesn't make any difference temps wise.

I'm curious as to whether the additional 2 sticks of RAM will have any effect on your overclock.

Ted

[David Roch 1,926]

I don't think so.
Not in my case anyway, no negative nor positive effect on o/c.

@Rob Ainscough quick question - did you connect the extra CPU 4 pin power connector on your board?  I recently upgraded to an i9 9900k but I've been using my existing Corsair AX1200i PSU which I don't believe has the extra power connector.  From what I've read on some forums I've seen they say its not necessary.  Im currently overclocked to 5.0ghz on all cores (i forgot what voltage Im currently at, I think 1.3v).  Just wondering if this extra connection is worth a PSU upgrade or not.  Right now temps have been mid 70s on most benchmarks, (Cinebench, timespy, Prime).

 

Also - does anyone have an idea what a safe daily voltage is if temps are in check?  

[Ted Striker 329]

That's encouraging to hear. On older systems, a higher overclock could be obtained with just 2 sticks of RAM.

Not the CPU, but I may have to adjust the timings and/or RAM voltage ... but I'll let you know as soon as they arrive and installed.

Are you referencing the EATX12V_2 power connector?  It's recommend (warning) that both 8 pin and 4 pin are connected or else you might run into heating issues.  Don't think you need to buy a new PSU, there are adapter cables you should be able to use with your existing PSU ... also think my ASUS box contained such an adapter which I don't need.  Per manual:

Cheers, Rob.

I'm running 1.5v daily and under extreme loads I've seen a very short peak of 93C (coolant temp is about 10C) ... average CPU temp is around 70C in P3D heavy loads at 5.3Ghz, cache at 4.8Ghz, AVX (5.1Ghz) ... idle is 19-21C.  No speedstep, always at 5.3Ghz or 5.1Ghz AVX.  I have thermal trigger at 105C.

Cheers, Rob.

Sweet - thanks for the answers to both questions.  I'm going to double check the little velcro bag the PSU came with to see if I can find the cable.  I'd prefer to hook it up if its meant to be there.  Who knows, maybe a higher more stable OC haha?!?!

PSU's almost always come with two. It should be in the PSU cable bag.

FYI, I only have the 8-pin one connected and it's absolutely enough for a non-SLI rig.

[pegruder 64]

Yea I can't find it.  I might see if I can order a spare but worse case it seems itll be fine.

Since the 32GB kit of the TridentZ 4400 is the only RAM at that speed on the QVL for the Maximus XI Formula, it will be interesting to see if you can get XMP to work or at least a higher speed.  I know that it won't be a matched set of 4, but close enough maybe?
