Cool. I can try change timing only In 2-3 hours. I can write process on video (if it helps).

But with the same code motherboard freezes at start when i trying to overclock CPU ( solved by adding the voltage on cpu Vcore). In manual said 01-59 codes all about memory problems. But my memory with defaulth timings and 2133Mhz freq. (without XMP profile load).
BCLK overclocking

sorry for my english


As Xaltar said, the only time the Dr Debug/POST codes indicate a problem is when the PC is starting, and the PC does not boot/start Windows or whatever your OS is.

The POST codes are displayed on the Dr Debug display as each POST process is run during the entire POST procedure. That is normal. If a POST process fails for some reason, then POST stops, the code of the POST process that failed is displayed, and the OS boot process stops.

If you see a code on the Dr Debug display when the PC is being shutdown, it does not mean anything at all. The POST procedure does not run when a PC is being shutdown, any code displayed at that time does not mean anything.

If your PC boots your OS fine, you do not have any problem with your memory as far as the POST tests can find.

The memory controller is part of your Skylake CPU. If an over clock fails because of too little voltage, any number of things can go wrong in the CPU, including a memory problem.

But CPU pass 2hour prime95 4.5Ghz on 1.27v (if i luck to run without freezes 04). And can freeze with 04 code only at start. And i must set 1.36 just for no freezes PC start. Maby exist a way to increase the voltage only on startup.

wardog, 19.15.15.36 (rc1) timings don't give resulth (

Happy, please list out the hardware of your box by make and model, and please include the PSUs age and if the PSU is plugged directly into the wall or not.

Too, let's try taking them off XMP and manually setting them at their 3200 SPD timings, for starters.

tCL - 16
tRCP - 16
tRP - 16
tRAS - 36
tRC -52
CR - 1 (and if there's issues, change CR to 2 and retry)
DRAM Voltage - 1.35v

With the above timings made manually, if the sticks are in slots A2 + B2, try shuffling them into A1 + B1 and reply back the results.

Whether it's plugged directly into the electrical wall outlet, or if it's plugged into a multiple outlet power strip.

Is this right? You have a 4.5GHz over clock on an i5-6400 CPU? That is this processor:

http://ark.intel.com/products/88185/Intel-Core-i5-6400-Processor-6M-Cache-up-to-3_30-GHz

That is not an Intel 'K' processor, so any over clock must be done with a BCLK over clock. That is fine if it is true... for the CPU. But for memory, which can also be used at a different BCLK, any random BCLK value might not work.

How are you over clocking an i5-6400 processor to 4.5GHz? What BCLK are you using, and what core multipliers?

bclk value is 166.7500 x 27 mult.
