Indeed. I mean yesterday I learned that sleep mode can't be used on a PC without GPU drivers installed, for some reason.

 

Welp, enabled XMP on the RAM and it won't pass POST now. I need NVRAM reset? FN + D at boot?

Or is it supposed to turn on/off consistently for like 7-8 times before it works?

Edit: Ok, I cannot seem to get this system to POST with that RAM beyond stock.
Anybody up for helping me out a bit?

 

@Mr. Fox once mentioned setting XMP, switch to manual, increases the tREFI for the g.skill. He mentioned you could play with some other timings, but I think that was for a boot solution.

It will not even allow me to enter the BIOS with XMP1 enabled, or with his settings copied from Manual. Each time I try to use either XMP or manual, it simply fails to boot. I have had to use FN + D bios defaults at least four times tonight alone.

Unless I have to set the memory to XMP in multiple places in the BIOS? I've seen it allows me the option in something like 3 places... if that's the case then that might be why.

 

Hmmm. Have you tried to slowly step it up from stock, loosening timings as needed, but not jumping to 3000 or 3200?

I haven't, mainly because I'm just slightly annoyed at it right now. I was hoping they'd have tested 3000MHz and made sure it was stable before sending but it came at 2400MHz. Le gg.

I'll maybe give it a run through tomorrow. The forum being broken for many is making replies on this slow as well. I will say though it's one of the more annoying things to get a system and then have to run through things like this. I was expecting at least Kaby Lake to just boot supporting it.

 

Well, best laid plans and what have you! I'm thinking it could be anything from the IMC, a timing being too loose or right for the board, a ram slot being defective, etc. Do you have 2 or 4 DIMMs? Have you made sure they are all seated well or tested to make sure no errors are kicking at stock? I know you just got it, but am unsure what has been done to this point for troubleshooting...

Didn't realize the forum was screwing up, but tapatalk is working fine. My ram on my desktop was the most annoying to get right, then I had to start over with the ram after the new bios version. Edit: In fact, to get 4000 without errors I even have to have each DIMM in a specific slot. If I put them in any other slot, I get errors with my current timings...

Meanwhile, found a site that has gotten the price on AMDs right the majority of the time putting up the price of $490 for the flagship 3.6/4.0 8C/16T Ryzen, so I may have to sell my current MB and CPU in a month or two!

4 slots, 4 x 8GB G.Skill 3000MHz.

Windows seems perfectly fine, it simply refuses to POST after I make seemingly any change to the memory profile in the BIOS. I also have the Prema mod and i7-7700K; IMC should be the literal least of my worries for XMP1

I have not checked seating, but I've used it for a full day without so much as a hiccup, just that it's running at the absolutely atrocious timings of 2400MHz 17-17-17-39-T2 right now.

Tapatalk does work fine.

If you're on mainstream it'll be a hell of an adventure, do keep us posted.

 

I will! The AMD MBs seem like either the asus crosshair or asrock is the way to go (just broke that down on the Ryzen page for what is known).

It's harder to figure out without the system posting. Can you even tighten primary timings? (Assuming you can't because you said any change is no boot). IMC should be fine, just throwing out all possibilities.

Can you manually set voltages for the ram? Also, have you tried increasing the voltages on the VCCIO or System Agent to help stabilize faster speeds?

Sent from my SM-G900P using Tapatalk

 

I see. Sounds good.

I'll try tightening primary timings at 2400MHz tomorrow.

I overvolted the RAM at one point when copying @Mr. Fox's settings. It still would not boot. I did not touch VCCIO or system agent; the CPU is still bone-stock.

 

Ok, I'd say start with the CPU overclock first, as that gives the most performance (and is generally where I start). Then I move to ram because I want the ram to be stable at my overclock. But those voltages will likely help, even though 3000-3200 should be about reachable at stock. 1.1-1.2V on each of those should be more than enough to remove that as a cause (my 6700k can do 1.1 on each for 3733, whereas I use 1.25 on each for 4000).

For ram voltage, 1.35 should be fine 24/7 if temps are good (or even 1.4, but that is pushing it for lower air flow, potentially)...

OCing this CPU isn't happening anytime soon. It needs delidding and I probably need a copper shim to make the heatsink contact more proper. Once I get those things sorted out, I'll aim for 4.6-4.8GHz daily driver. But even so... RAM will help me more than that overclock.

I'll figure it out later. Maybe I need to remove all but 1 stick then boot with the profile then add in more sticks or something tedious like that I noticed Johnksss saying a long time ago, possibly to Tbonesan.

 

Johnksss did say that, in order to allow the MB to train secondary and tertiary settings.

But now I get what you're saying and why you stated with the ram. If nothing else, I'd be seeking 4.4-4.5 undervolt (or I'd actually have my razor blade out with that cpu right now, trying to avoid scraping it on the pcb or pushing too hard while working around the corner and slowly spreading that to the length of the ihs). Are you planning blade or delid tool?

Sent from my SM-G900P using Tapatalk

 

I see. Might have to do that, then. Maybe in the coming days I can get more information about how to begin.

Yes, 4.5GHz flat with undervolt is the good place to start. I have a rock-it delid tool, but I'm waiting until I have the shim. I dislike opening this laptop more than my P370SM3, since I have to kind of pry it open and my screwdrivers do not reach the deeper screws (I have a screwdriver & 24-bit head system, but the screwdriver is too thick and the bits not long enough, so I have to shove the bits in and by-hand turn them to loosen and remove the screws). Then I also need to take stock tests and then tests after I remove the silver airflow blocker. I'd like to just dive at this, but I actually have to be a bit methodical since it is for a review, hehe.

Edit: I was planning to sell the P370SM3 and use the cash to get more/better tools, but it seems once again I'm a little backwards, haha.

 

Got you. Another thing to try is just using two sticks. Pull two out and see if it allows for an overclock at some point. Every once in awhile, a bad slot happens and it runs stock, but nothing else, or the other timings are throwing it off with all slots populated (if it is two dual channel kits, the two kits might be off enough to not be sympatico). I know for getting my desktop stable at 3733 14 16 16 32 280 or 4000 16 20 20 40 310 (I think, might be 21 21 42), I have to have each DIMM in a specific slot to not kick errors (board is officially rated for one DIMM at 3866 and you have to bin boards to get over that for this model). Took me some playing to find which slot each belongs in (4x8GB G.Skill 4133 19-21-21). I also discovered if, at the faster speeds, I'd get row hammer bit flips if I set the tREFI too high.

Also, many tests show like that video on performance scaling, but it really drops off above 3600. Not to say no improvement, rather, it just isn't as good as going from 2133 to 3000.

Yeah, I'll give that a shot later. First I'm trying to make the new thing my primary machine. But it'll take a little bit, lots to install and set up and prepare. I'm still (slowly) copying things to a backup drive to make sure I don't lose anything.

I'll use the RAM as-is for now and see how things work out. Hopefully I won't need a mobo change or anything of that sort. Though this board is indeed rated for 3333MHz.

I knew about the 3600MHz scaling drop-off, though. It hits around the 3200MHz range too. I ideally was hoping I could manually get the RAM to 3200MHz 15-17-17-39 or so, but first we'll try to get it to boot at 3000MHz. I have time, I can play around now. The machine otherwise works flawlessly as far as I've seen. Wish I could disable trackpad without installing CCC though, but I guess I have to do it.

 

Remember to either use the switch in the bios or edit the file to disable xtu if you don't want it...

I'm sure others will be able to chime in over the next couple days to give machine specific info. Did you get the DM2/3 or the KM1?

Sent from my SM-G900P using Tapatalk

 

Certain it's DM3. KM1 is barely in for testing, and I was able to install chipset drivers on W8.1, as well as Prema mod is working. Plus CPU-Z says Z170 xD

 

Just wondering to see if you're the first to have one (for a good performance review). But makes sense... Just didn't know if the KM was out yet or not.

Sent from my SM-G900P using Tapatalk

 

Well I do have the 780W brick, so that can get reviewed haha

 

Yes. Boot with RAM sticks in slot 1 and 4 and apply your XML.
Then you can populate the other slots once they're all settled in.

I’ve got 3200 running rock solid with the 2 x 8gb G.Skill 3000 using the following. These are 95% based on brother Fox's blood, sweat and tears. I only lowered the tRAS to 40.
I'd like to push more when I have more time.

Mem Ref Clk 133
Mem Ratio 12
tCL 16
tRCD/tRP 18
tRAS 40
tCWL 18
tFAW 39
tREFI 12480
tRCF 560
tRRD 4
rTRP 12
tWR [24]
tWRT 0
NMode 2
Voltage 1.30

 

1 and 4 are both under keyboard? Or one on either side? I know the slots are actually marked if I look at them but asking because lazy at 6:45am xD

Sent from my OnePlus 1 using a coconut

 

Yeah unfortunately 1 stick either side. 6:45am..damn son! I thought I was bad having last coffees at 1:30am.

 

I would stop working on the hardware when it gets late or first thing the chance of doing something silly increases a lot

 

I was asleep but I woke up. In bed on the phone is all, not opening that thing for many an hour yet!

This is why I remain in bed and just ask xD

Rough rule of thumb: tRAS= 2xtRCD (although 2xtRCD + 1 or 2 sometimes works better with some sticks) - this is just a window, so lower is not necessarily better and higher isn't necessarily worse.
Try to lower the tRFC as low as possible without errors!
Try to raise the tREFI and tREFIx9 as high as possible without errors. May cause row hammer bit flips. If so, start by lowering the tREFI.
Command rate seems to effect the performance slightly less than DDR3, so don't worry about it being set to 2.

Okay @Phoenix so, I am typing this entire sentence with my eyes fully closed on the P870DM3. I haven't really used the keyboard for more than a day and I haven't even installed CCC to disable the trackpad, so any mistakes will fall where they may. Let's see if I can screw up or pull through! =D

----------
I think I did okay

 

gHacs latest news http://www.ghacks.net/2017/02/11/maxon-cinebench-benchmark-software-with-comparison/ Maybe a little late?

 

I know, it's been around for how many years?

 

CbR15 was posted by Guru3D in 2013. They are pretty upgraded on some software http://www.guru3d.com/files-details/cinebench-15-download.html And most people still talk more about the older CBR11.5

 

TIL if you middle-click a folder in your taskbar, it opens a new "This PC" window (as if you did Windows key + E).

Just thought everyone might find it useful xD

 

Middle clicking my mouse on the taskbar does nothing

 

No, middle click a folder. Like some already open folder you've got. Saves using win + e or opening the start menu

 

ah now it worked. thanks bro, nice shortcut

 

This works for any software that can run in multiple instances.

I actually do this a lot, imagined that everyone knew about this...

Also, I remapped middle click on my G502 to be a better button...

 

Let me share my bios memory settings as well, 2x16GB 3000MHz running at 15-16-16-35-2T, passed 8 hours of MemTest86 and 5 hours of RealBench with 32GB ram selected.
These are Corsair memory installed on the bottom side. Maybe some G.Skill can also do, since they both use Samsung chips.
Occasionally I got no boot when I was setting these values, but once I set them successfully, they can pass hours of stress tests. I guess it might related to the nvram of writing chuck of data.

tCL == 15
tRCD/tRP == 16
tRAS == 35
tCWL == 17
tFAW == 28
tREFI == 10400
tRFC == 467
tRRD == 4
tRTP = 10
tWR = 20
tWTR = 0
NMode == 2

Read write speeds are not shiny anymore in front of 3200 MHz, but latency is still good.
46.4ns on Windows 10 with no optimization, it might perform better in Windows 7 or XP.

 

What programs do you guys use to check for OC stability? I've been able to OC to 4.5 Ghz on the 6700k but I keep failing after 30 min of RealBench. By any chance does Liquid Ultra degrade over time?

 

CLU IS FINE FOR THE LONG HAUL unless air is in there or you use it in cold temp extremes.

As for stability, it depends. Real bench takes more voltage to pass than some others. I did wprime loops and passmark burn in test, but aida 64 stress tests can work. I hold real bench loops right behind IBT and P95 on heat/voltage needs, meaning unless you need that much voltage every day, you are making it run hot without a benefit for the extra voltage (except slightly less chance to crash)... So it depends on your goals.

Overall, delid, check if you need a shim, New thermal pads, etc.

Does this pass TM5?

 

First time using TM5, default settings:



I have been always using MemTest86 to do 4 full cycles with all threads on.
Found out the memory plugged in the bottom is more stable than plugged in under the keyboard.
Forgot to mention, I have +50 offset for uncore.

 

Nice clocks

 

Now i'm going to need you to run it correctly this time....
You need to run it in Admin mode. Which means setting the compatibility to admin and then reboot laptop. Then run test.

2 minutes is nowhere near long enough for 32GB of ram. Should be like 10 to 12 minutes.

 

Alright, followed with what you said.
No wonder I felt so short of the first run, and doubted the reliability of the program.
Here is it, took about 10 mins:

 

Thank you @Coolane
You have a first Gen machine correct?

 

No problem.
Yup, it's the original DM1, still using the skylake bios.
If I have chance to try out KBL one day, I might try to push it to 3200 and see what timings I can get.

 

Is that that stock 3000Mhz RAM or the 2800Mhz?

 

Default is 3000MHz with 16-18-18-39.
With the 6700K, I can't get pass 3000MHz even I added voltage to 1.35V.
The only way to pass 3000MHz for me was to overclock the BCLK through XTU.
I am guessing the CPU or the platform is limiting the memory frequency/multiplier.
I heard that Kaby Lake is more lenient on memory clock, seeing users running 3200MHz without problem.
Sometimes I dream about running 5000MHz+ on desktop, that might result in 30~40 ns latency, closed to the speed of 128MB L4 cache in Iris CPU,

 

so after a bit of waiting i got my book back from RMA, the reason the XMG Bios update failed, according to the reseller, was that my GPU caused the EC relock issue which killed my Bios, sounds weird to me but nvm got a brandnew book. So, to get that 7700k action going, i have to update to 1.06.xx can i use the stock clevo one, or do i still have to use the XMG one, where the "S" is the boot and bios logo.

 

Question...When you flashed the last bios....Was it by EFI or dos mode?

 

EFI

Edit: EFI Shell to be exact, used the XMG Instruction .pdf
