I'm having a hard time getting my RAM stable at 3200mhz (what it's rated for). I tried getting the system agent up to 1.3 while gradually adding, and I keep getting errors on HCI memtest. I wonder if I need to add more dram voltage than the rated 1.35. Default 2133mhz goes error free on memtest.


The voltage can be what it needs to be (within reason). The guideline is based upon how these two rails usually react. It is not a safety measure.

I know each sample is different, but vccsa ~ 1.3 seems kind of high. Have you tried 1.10 -> 1.15?

That, and try 1.37-1.4v on the ram and see if it helps. There is not danger for the ram at those voltages but 1.3 VSA/VCCIO I wouldn't like that myself.

Obviously depends on the CPU and memory configuration, but I'm still working my sample down between using the system. Currently at 1.08v for 4x8GB 3400.

Per Raja's broad well guide ram over 3000mhz may need up to 1.3 SA for stability.

I went up by 0.05 intervals multiple times. I'll try increasing the DRAM voltage a little bit.

Hello

GSAT is currently the best tool for isolating memory only errors. Issues can be found in hours with GSAT that may take days to uncover with testing utilities in Windows. But like most things one needs to know what the GSAT results are telling them and adjust testing accordingly.

Days? more like eons with 32GB or more. smile.gif

well not pushing the 6950x any further since it died. This would be the first time I killed a CPU in my 25 years in the computer industry and course it had to be the $1,700 one.

I've been running it at 1.352v with uncore set at 3.2GHz auto voltage and memory at 32000 auto voltage and my CPU died right after I exited out of GTA5 and after a reboot. Temp was very low like 33c because I was in windows for a bit with nothing open before the incident, currently I have 11x140 rads with noctua fans and only have 2 GPU 1 CPU block driven by two D5 pumps at constant full speed.

I'm not sure if the motherboard killed the CPU or the CPU caused some damage to the R5E10 motherboard. I installed my old 5930K on it but during post and before it loads the OS I hear some low frequency humming coming from my USB connected Bose audio system.

I'm using the beta BIOS from the Asus website 0801.

Let's just say I'm no longer enthusiastic about the broadwell-e chips now and might sell the replacement one unopened and go back to haswell.

@Artah - OUCH! Sorry, mate! I lost a 5820K last year but it was a PSU casualty. Good luck!

ouch. but that is what the ITP is for. does the board boot the 5930K successfully?
