Tighten Timings

[Hopper64]

I have this GSkill 8400 kit with default 40,52,52 timings working quite well with 1.5V VDD/VDDQ. Tightened the timings some. Any room to go further? 36, 48,48? Is 1.5V adequate?

I will try that today and see what I come up with.

So I will find a stable XMP as a baseline.  And then report back. Thanks

XMP is stable at 6600 anything above that game will freeze it will load windows everything but anything above 6600 once in game it will lock up during game. So XMP 1 with everything set by board auto stuff it is stable at 6600. Now what is the next suggestion to adjust since I know 6600 is stable. Passed test and real world test at 6600. Thanks

8400MT very much depends on the CPU silicon quality. Does every adjustment made result in Q-CODE 55? Are you using a CPU contact frame?

[MtnMan]

Yes I have read on here and have read you have told I think everyone that I know after reading it does factor in. I have a Ryujin III AIO in ROG Hyperion Case 1200watt Thor battery and one of those Thermal Grizzly cpu holder. I have changed SA, VDD/VDDQ and MC voltages. But after reading on here and the OC forum i read to much everyone is a expert or they fuss cause the QVL blah blah I just want to get it to work and get what I can I may not get 8400 but want to try. But reading so much has me scratching my head. 
Amber light only on XMP 1. XMP II no lights. But I don’t think I am making the correct adjustments. 
tested today as suggest by hopper try XMP until it’s not stable well tested and at 6600 it pass tests and real world test. Suggestion on what to tweak now to try and raise that up. Yes anything over 5600 is considered OC but I know or should based off reading making a few voltage changes can pass or fail. Suggestions on what change to make and test next. Thanks

Remove the contact frame. Not being able to get over 6600 suggests it's overtorqued.

[MtnMan]

Really? But my CPU temps are fine. What does the contact plate have to do with the ram? And it’s the new version that don’t have to be special torqued not the old one its the new version. I had the thermal lake one also and couldn’t XMP either. Seriously? 

[Hopper64]

The contact frame might cause memory stability issues if it is overtightened due to impingement of the underlying pins in the socket. Scone is quite serious with his recommendations. Helped me numerous times. It’s part of the troubleshooting process. Consider using the native ILM to rule out the contact frame as an issue. You can reinstall it later if needed. Otherwise you are not going to know for sure and you may be downclocking a memory kit.

[MtnMan]

Ok. I figured he was serious. I like his explanations helps educate. Alright will follow the advice guys. Thanks

You may also consider a 7200 GSkill kit to test as well and just keep the 8400 for another build later. I had a GSkill 8000 kit working fine on mine and was never successful stabilizing the 8400 kit until I installed this ks chip. So it may take a while and the right hardware to get your stuff working the way you want. It is definitely a lottery. Takes months sometimes.

[MtnMan]

I might consider the 7200 gskill have an 8200 coming also. But let me get this contact frame changed out that I have never used till this build so we shall see and I will let you all know if it will XMP higher. Get back to you all within the week. Thanks for the guidance you two appreciate your time.
