3200mhz XMP unstable
3200mhz XMP unstable
Hello,
my RAM is running at advertised speed but it's not stable. When I run at 3200MHz, rounding errors in Prime95 keep me from getting consistent performance. I've tested speeds from 4 to 6GHz, voltages between 1.32 and 1.37V on my i7 6700K, and even adjusted VCC/VCCS up to 1.25V without stability. However, at 3000MHz with 15-17-17-35 timings and 1.35V, I'm stable at 4.6GHz, 1.32V, 1.12V CCCO, and 1.12V VCCS. Anyone know what's happening? I have the latest BIOS.
MOBO : MSI Z170A GAMING M7
CPU : I7 6700K
PSU : XFX BLACK EDITION MODULAR 650W
My XMP configurations aren't functioning properly on their own. I had to manually tweak the BCLK and CPU ratios.

Hallo,
habe ich ein Problem mit meiner RAM-Leistung. Bei 3200MHz funktioniert alles stabil, aber bei 3000MHz und bestimmten Timings und Spannungen (15-17-17-35) ist es nicht zuverlässig. Ich habe verschiedene Frequenzen ausprobiert, von 4,6 bis 1,35V, aber immer Schwierigkeiten mit der Stabilität. Auf meinem i7 6700k und XFX BLACK EDITION MODULAR 650W PSU gibt es offensichtlich ein Problem mit der Spannung. Ich habe schon gesagt, dass ich die BIOS aktualisiert habe. Haben andere Nutzer ähnliche Erfahrungen gemacht? Ich hoffe, das hilft.
u mean more than 1.35v yes? because from corsair site it says 3200mhz, 1.35v, 16-18-18-36 timings. On these settings i'm perfectly stable, on low cpu voltages. I want to test my memory with memtest+. Should i test in stock settings or stock settings plus xmp?
Sooo..
I've checked my RAM at 3200mhz with other configurations using memtest, and there were two failures in seven tests. Then I tested it with the default settings, and no failures occurred. So what's the issue? I believe if it passes on default settings, the RAM isn't faulty.
I performed memtest+ over two nights using the specified hardware and frequencies, and it performed very well. The issue with stable performance on XMP settings might be due to compatibility or configuration differences, even when using standard settings.
What GPU are you running? If it consumes a lot of power, your PSU might not be enough. I thought the problem was just about getting the RAM to stabilize OC on its own, but with the CPU OC too. I guess the BCLK is the same for both, just increasing the CPU ratio?
sorry to ask the obvious, but just in case... which dimensions of the slots have the RAM installed in?
