Been wanting to learn to overclock my current build so I can get it running correctly, started another thread thinking the RAM was the issue but wasn't so I'm thinking it's just not stable but other than using the XMPI/II I don't know almost anything about overclocking as I've never seen the point personally. Thing is the setup for both XMP's sets the RAM to 2666, like I want, but games always eventually lock up the system. I've already tried new ram so now I have 64gb's of ram as faulty hardware isn't the issue, and also a new gpu because we thought that was the problem the first time. I've so far read around online that unstable overclocking can make your computer freeze/lock up and/or BSOD randomly or very often if setup wrong. I figured the XMP files would automatically be alright as it's what the RAM was tested for but maybe not. If anyone has any video's or guides how to do it step by step or if anyone has a similar build or the same exact build! Been tempted to take the ram a little lower and possibly give the CPU a couple steps up for voltage as that can freeze/crash your computer too I'm sure.
I am in dire need of a BIOS downgrade for my 2017 Corsair One™ Pro (CS-9000011-NA). I'm looking for an early version of the BIOS, one that will allow me to manually set the PEG0 - Max Link Speed back to Gen1. I think I was running either version 4.QF or 4.QQ, and that was the last time my system was running consistently well. I understand there have been major security updates in the meantime, but what's the point of security if my $2300 USD computer is not working in the first place? Here's what happened: A week ago, I (finally) decided to do a BIOS update. I have been running the original factory BIOS version since originally receiving it back in 2017. First BIOS update I tried was version E7A66IZ1.4C1 (aka "the Spectre/Meltdown BIOS Update"), and then a few frustrating days later I installed and flashed the current version, 4C3. For the record, I followed all instructions as provided on your forum sticky, and reset the CMOS after each successful update. (Understand that I've been building and fixing PCs since the '486 days, so this isn't my first rodeo. :biggrin: ) Ever since applying the last two BIOS versions, where you invisibly locked the graphic card at Gen2, I've been unable to successfully boot my Pro into Windows without it locking up 4 times out of 5. (At this rate, I fear that I will have to replace the power button.) I'm at my wit's end by this point, since there seems to be no combination of BIOS setting or Windows re-install that will bring me back to stability. If anything, I'd like to just take my system back to its original configuration and pretend none of this ever happened. Note: My Pro is running a clean install off a Windows 10 202H ISO straight from microsoft.com. I've been through a myriad of BIOS settings, starting with the default optimized settings, and I'm still unable to attain the stability I had before the BIOS update. Cold starting the computer will usually result in a lock-up before the OS is even booted, sometimes a spontaneous restart happens where the Pro powers off and then back on, and even if the Windows login screen does appear, it will usually lock up before I can finish punching in my 4 digit PIN number. I recognize this behavior from a few years ago, before I found the Max Link Speed setting in my BIOS and switched it to Gen1. System ran fine afterwards, booted into Windows every time I switched it on. I know I'm late to the game on getting the PCI-e ribbon replaced (>1 year past warranty), and I'm sure there's a cost to video performance by throttling down to Gen1, but I NEED a working computer now, not an aluminum $2300 desktop conversation piece and angry clients wondering why I'm not meeting their deadline. Thanks.
CPU: i7-8700k Motherboard: ASUS ROG STRIX Z370-E GAMING (bios 0605) Memory: CMD32GX4M4E4000C19 I am trying to get my memory to run stably at the specs on its product page Speed: 4000MHz Tested Latency: 19-23-23-45 Voltage: 1.35V However, memtest86 and prime95 validations quickly show memory errors. I was wondering if anyone could help me find out if I can dial in any settings to get stability. My core overclock to 5ghz has been validated, but I am doing all of my ram testing without my core overclock first to eliminate it as a source of instability. I know my memory isn't on the motherboard's QVL, but it seems I never see dominator on vendor lists, and an identical Vengeance kit is on the list. I've heard the same ICs are on both products, just higher quality and better validated ones are in Dominator. I'm entirely open to the possibility that this isn't the case and Dominators just have a sexy tax. I have tried using XMP and manually applying the paremeters, as well as upping VDIMM and VCCSA + VCCIO and no luck. I've noticed that if I apply the parameters of the next fastest Dominator kit, Speed: 3866MHz Tested Latency: 18-22-22-40 Voltage: 1.35V I do not throw any errors in a default memtest86 test (other than "RAM may be vulnerable to high frequency row hammer bit flips.", is this a cause for concern?). A prime95 test on this seems stable, at least much more so than the XMP parameters. Is it possible for me to achieve the specs on the box, or is this a case of "stability isn't guaranteed for these specs" for my motherboards speed support and the listed RAM specs?
Hi everyone, i write this post cause i am really running out of ideas and hope to hear about some similar problems someone solved. Duh. A bit about me: i am working on computers since about 20y, overclocked my first 486 dx2 66mhz without knowing what i did (at this time), then later started again with "modern hardware" (Athlon Classic 750mhz to 1,1Ghz with Goldfinger Device), killed a few Athlon XP's, etc. besides this i work in IT since 15y. long story short: i believe i know a thing or two about hardware. Anyway, it all started with the idea to build a new system, nothing overpowered, but since i was still working with my 6y old i5-2500K system i thought it is about time. i spent a while with choosing some proper components and came up with this list: MSI Z170A Gaming M7 Intel i7-6700K Alpenföhn Brocken 2 (CPU FAN) G.Skill F4-3000C15Q-32GVR DDR4-3000 15-15-15-35 1,35V - 4 Sticks, 32GB (4x8) - i know, you will ask yourself why i bought G.Skill and write in the Corsair Forum, i will get to that later OCZ OCZ700MXSP (still had it from the old system) MSI Geforce 1070 GTX Aero 8G OC i mostly need stability in my systems, so overclocking the hell out of it was never the plan, but therefor i choose a bit higher default clock rates for the memory. The MSI Z170A Gaming M7 is (on paper) able to run the memory up to 3200mhz without any need to overclock the CPU. So i started to build the new system, everything went well, system posts at first try, everything went really well. i read about problems with XMP Profiles, so setting the memory to those and get a post at 3000mhz right away made me certain - i like this system. few days later i thought - well, i should bench a bit and run the proper stability tests - before i even started with memtest86 and prime95 i got some strange errors on some of the benchmarks, pointing out the memory might be bad. to make sure i startet memtest86 and prime95. Prime95 had troubles right away, after a few minutes one process after another crashed. memtest86 also took only test #6 and hat thousands of errors in a "full run" (4 times). so i started to clock manually down (still at XMP Settings, but clock down to 2133mhz). went fine. i tweaked around a bit but nothing more then 2400mhz was stable (rest at XMP settings). I started to put more juice to the memory (since 1,35v gave actually only 1,31v), heard about the VCSA and VCIO tweaks that should help - but it didnt. i got desperate so i turned all relevant voltages close the recommended max. no changes, not stable at 3000mhz, but always posting. so i tested every memory stick in every memory slot - and was supprised. not only all the memory was good at JEDEC settings, they all where fine at XMP settings too - as long as i only tried one at the time. just to be sure i ordered another set of memory (Corsair CMK32GX4M2B3000C15 DDR4-3000 15-17-17-35 1,35V - 2 Sticks, 32GB (2x16)). Put them in, set the memory to XMP aaaaand nothing. Didnt even post. Again same tests - both memory sticks in any slot running fine at XMP. further i found out that the problem is attached to use of dual-channel. as soon as any configuration is set up that would activate dual-channel, the memory would fail at speeds above 2400mhz. well, then it must be the board cause in the meanwhile i changed EVERY other component EXCEPT the CPU. till now i never ever had a defective CPU, so i assumed it could not be the problem. So i blamed MSI, still friendly and patient i opened a support ticket at MSI. 2 weeks later and no changes. i flashed a few bioses, cleared CMOS for my friends at MSI about 50 times on 5 different ways - no changes. i triple checked the pins at the cpu socket, nothing bend. the cpu cooler was not mounted to strong, when i checked first time i saw that my artic cooling 2 from the older days was not even spread over the cpu, and i really really was carefull cause i heard a lot about problems resulting from use of too much power at the wrong place. In the end MSI told me they cannot help me unless i change the CPU - what a bulls*** i thought to myself, went to the next store, bought a Asus Z170A Gaming Pro Aura, came home, changed the board, double checked the pins at the socket, build everything up, put in the corsair and fired up the system. again, first time post, everything fine, system boots, everything stable at JEDEC. then came the moment of truth - set memory to XMP, the Asus Board asked another question regarding some higher voltages for stability reasons - i said yes, cause i wanted to see it work. well. it didnt. same msg like the MSI board threw at me. too much OC, blahblah, unstable, blahblah, reset to default settings, blahblah. ok... i thought. there must be a explaination. talked to my old friend aunt google, searched for "dual channel xmp no post" and found a few things, mostly things i checked already - "socket pins", "all memory slots good?", "all memory sticks good?", etc. nothing that really helped me to solve the problem. i bought 3000mhz memory for a board that says it can take it but it will not run stable like this. then i found a post from a guy who had a similar problem, cant find it again but it was pretty recent. one of the answers was that with the skylake Arch the memory controller went from the board to the CPU, i didnt knew that but that sounds like a lead. in the intel ARK i found a spec for the i7-6700K saying the memory controller supports up to 2133mhz in dual-channel mode. no f***** way - really?! come on, rly?! well, and that is the end of my journey i had for the last few weeks. My question to you brave guys (i mean, if you still reading this my kudos go to you) who are still here is: is this the answer? is it luck (like chances to oc a cpu) how high the clock can go in dual-channel? since the memory is advertised with clock rates up to 4000mhz in special made memory kits for the skylake platform (Ripjaw 5, Corair LPX, etc.), with mainboards, advertised to manage memory up to 4000mhz - i just find that hard to believe. Do i have to be happy to get 2400mhz in dual-channel stable? i bought all of that hardware at amazon, i still can send back the CPU - but i really cant tell if the CPU is the problem. In Kaby Lake the Dual Channel clock is spec with 2400mhz btw. i still have all the components here (except a spare 1151 CPU) and actually i dont care so much about the 1% performance difference i would expect in compare between 2400mhz and 3000mhz, but it is a matter of just finding the goddamn bug in here. i am happy for any feedback. thank you.
