    Intel 530 on 6700k screen flickering, artifacts and more

    Hysz

      Hello. I recently purchased new PC, with 6700k CPU, Gigabyte Gaming M5 motherboard and 16 gigs of G.Skill Memory [3000mhz CL15], I added M.2 drive as my main storage and system. Everything runs on Win 10 pro. I use my PC mainly to edit photos in RAW format, using software called Lightroom.

       

      After few days problems started to arise. 1st was problem with booting with anything higher than 4000mhz on PC [100x40], then, after I figured out relation between CPU and RAM everything was smooth, until I started to actually work. Lightroom has rudimentary GPU support, so I enabled it. After few hours, my screen starts to shake, mainly in lower 1/3rd of the screen, I see some artifacts [lines, dots], but only for a very brief time, less than a second. But the main problem is the black screen flickering, My screen just switches off for 1-2 seconds, and then go backs to normal. Indicator on my monitor stays as ON, it doesn't switch off. Sometimes I can work/browse for hours and it's OK [that CPU is a beast btw], but sometimes the black screen is  turning off my screen 5-10 times in a row, everytime for about 1-2 seconds. It's hard to change anything when it goes like that.

       

      My monitor is an old Asus that connects only by DVI or VGA [I am using DVI], and I use DVI-DVI cable from my motherboard. I checked it with my TV [DVI-HDMI connection] and it is the same, same flickering, black screen etc.

       

      I am using latest VGA drivers, latest chipset drivers etc. I am sure that my PC has not been infected by anything, as this has been happening even before I connected it to the Internet, also I use NOD32 and common sense, so I am sure that's not a case.

       

      Please advise me on what to do. I don't really have time to sent CPU for warranty, because I have deadlines all the way.

       

      PS: this happens on stock setting, it also happens on OC [4,5GHZ], I tried to change GPU from 1150mhz to lower [as low as 400mhz], but that didn't change anything. I used Intel Extreme Tuning Utility to do so.

       

      Thank you for any comment, or advice!

          GPU problem - YouTube

           

          I have added a youtube video link, showing how the screen flickers and does this black screen. I can answer any questions, and provide any details, I just want it to be fixed.

            It seems to be a hardware issue with the processor or memory compatibility issues. 
            I had checked specifications of the processor and it says memory support for DDR4-1866/2133, DDR3L-1333/1600 @ 1.35V, I did not see the processor can handle 3000mhz memory speed.

            If this is a processor issue, you could try running the processor diagnostic tool, this will test the processor and let you know if the test passes or fails.

              Hello. Test passed. memtest86 on my RAM on 3000MHZ passed as well. It is known that 'supported' memory speed is far, far lower than what can be achieved. I have purchased memory, that is compatible with my motherboard [MSI gaming 5], and I have purchased CPU that is compatible with this motherboard. Everything worked with speeds much higher than 3000mhz RAM and 4,5GHZ on CPU. I have been overclocking stuff for nearly a decade, so please, I feel a bit offended when you tell me that a high-end CPU cannot handle mediocre memory speed. It's built for that, even without my intervention my motherboards enables turbo and XMP profile which gives exactly 3000mhz CL15 and 4.3GHZ on CPU.

                 

                I don't really know if you try to blame third party or you just don't know what you are saying, but I have reverted my CPU back to it's native speed, and UNDERclocked my memory to 2133mhz. The problem still persists, albeit more rarely. I am just trying to rule out pieces of my PC and trying to pinpoint what exactly should I send under warranty, because I am sure if I send CPU, it will be sent back as 'test passed', and so will my memory if I would send it This is also true for my motherboard, PSU, cables, drives and even the case. So please, advise me on what to do, because for so many years, I've had millions of component combinations, and I have not seen this type of behavior before. Memory problem would cause BSOD, resets, etc. Drives fail with loss of data, unable to boot etc, GPU causes artifacts, bands, flickers, and CPU? I had seen one CPU so far that has been faulty, PC wouldn't even start to boot with it. I am fairly sure that this problem has something to do with internal graphics card, but seeing as it is inside the CPU, I feel like it's second CPU in my life that is faulty. Problem is, that I can send it, and it will return to me, because it will be tested under different environment, undeclocked perhaps. What is the point of buying unlocked CPU if you cannot overclock it? And what is the point of making 3000mhz memory, when there is no CPU that supports it? This is just ridiculous.

                Thank you for your feedback. 
                I just based my answer on the processor specifications, not your board specifications since you have third party brand (MSI)

                See the attachment in regard to memory support

                I have some reports about graphics flickering with customers using incompatible memory. Please test different memory.

                  I'll do that and post my resaults here, although I contacted few others with the same set-up as I have [ gaming 5, those RAMs, and this exact CPU ], and they never had a problem with it, running of course @3000mz and 2 of them even had CPU boosted to 4,8GHZ. Everything seems stable on other end. I have a very good contact with the local shop, so I can test whatever RAM I want, but I doubt that will change anything, because even underclocked memory [so that it fits CPU fake specs] produces the same effect.

                      G.SKILL Trident Z DDR4 3200 C14 4x16GB@2133MHZ - flickers.

                      Crucial Ballistix Sport DDR4 2400 C16 4x4GB@2133MHZ - flickers

                      Corsair Dominator DDR4 3000 C15 4x16GB@2133MHZ - flickers.

                       

                      I haven't checked ALL memories that are out there, my local store had these 3 kits, and I spent 2 days testing them under different conditions.

                       

                      Conclusions: Every memory @every speed produces artifacts, flickers and black screens [ black screen was rather rare when RAM was UNDERCLOCKED to 2133mhz]. Now, when the CPU is @4,0GHZ, memory can be @3600mhz even, nothing happens. I mean everything is OK when it is in his base GHZ, but if I change the ratio from  40 to 41, problems arise.  SilentiumPC Grandis XE1236 v2 < I got this thing as my cooler, my temp never goes beyond 60C, even in heavy strees tests. I leave cache mhz and graphics mhz at defaults. As I stated before, I contacted few people who have identical set-up as I have [userbenchmark.com] down to the HDDs I have, OS, etc. One of them gave me a safe UEFI set-up, that can give 4,8GHZ and maximum from memory, he stated that it works on daily basis, with heavy load about 4-10h a day [work related I guess].

                       

                      So I still have no idea what to do. I haven't changed the motheboard, because they haven't got one for this CPU at store, and because my OS wouldn't probably boot. I haven't changed my CPU either, because thy didn't have one that is compatible with my motherboard.

                       

                      So I am underclocked, with stock ratio for CPU, memory is 40% slower in benchmarks, CPU is about  30% slower, but I don't get that many flickers now. Still, everything is new, and I need to pinpoint something to send under warranty. Any clue what it might be, after what you have read? I can provide more details, I tested those RAMs @ every possible speed  [800mhz included, lol].

                       

                      EDIT: grammar.

                      EDIT2: I really NEED this stuff to be overclocked as much as I can safely. I work with some really heavy load, and even 5% increase in performance mean HOURS of free time, instead of chomping on PC.

                        Thank you for all the information. 
                        If this is still happening after working stock settings and compatible memory, this might be an issue with the processor itself.

                        I would recommend testing another processor, for warranty issues please contact Intel at

                          Hi, I really would test another CPU, but my local shop wont ship me next unit just for tests. These aren't exactly cheapest CPUs. Since then I have restored everything to stock, loaded my own memory, and it still does that blinking, flickering thing from time to time, it is more visible and longer when I overclock either CPU or memory. Is it possible for you to estimate how long would it take for service to test my CPU unit and send me back? I live in another country, so those values may not be correct, but I just wanted to have a number, like 1 week, 3, or more? At this moment it's my only working PC, and I have way too much work to just send the CPU and wait for indefinite amount of time.

                            It usually takes about a week and a half, turn around. If you are in a different country, I would recommend contacting your local support through the link I have posted earlier for more information about this matter.

                              Thanks for information. 2 weeks is so-so for my business. I will send all my components [cpu, ram, motherboard], and if all comes back as TEST OK, then I will just sell this CPU and buy something that 'supports' normal clocked memory [like AMD CPUs].

                                  Hi, thank you, but the vendor that sold me the unit can do that for me, I will provide every bit of information, but I still cannot exclude the motherboard failure. So far I have excluded RAM [and just a tip for others, I have tested memory from 2133 to 4000mhz, and every kit works with 6700k CPU without any problems, or configurations]. In upcoming days I will try to exclude motherboard as a problem, and then proceed. If it is a motherboard problem though, there is no sense in sending my CPU under warranty.
