Question Can I run RAM at 1.4V ?

[Nightlytm]

Hi good evening, I bought the FF3D532G6000HC30DC01 RAM (6000 at cl30) and the MSI PRO B650-S WIFI.

After testing both EXPO 1 and 2 I found out that EXPO 1 isn’t stable when testing it with Memtest86 (346 errors in total). Expo 2 was fine but it was running at CAS 40.

I was trying out “Memory Test It’ in the BIOS and the lowest CAS I was able to reach with a stable RAM (0 errors on memtest86) was 6000 32-40-40-86 but at 1.4V.

I know that this RAM module runs at 1.35V but is it possible to run it at 1.4V or would that be an issue in short/long time?

Thanks in advance

Does it run at stock settings?

If not, send it back for a new set.

What is the exact part number of the ram in question?
DDR2 ram might run at 1.8v, or, overclocked DDR5 ram might go to 1.45v.

Does the FF3D532G6000HC30DC01 come with AMD specific EXPO settings in the SPD or generic Intel XMP settings?

This review mentions:

"The TeamGroup T-Force Delta RGB (FF3D532G6000HC30DC01) RAM includes the Intel XMP 3.0 profile when using the effective frequency of 6000 MHz and 30-36-36-76 timings."

It's not always possible to achieve a stable overclock on AMD systems in the absence of specific EXPO values in SPD, if all you have is Intel XMP timings. Sometimes XMP and EXPO timings differ.

I'd be inclined to experiment again with EXPO1, but loosen the CL/CAS timing by one or two clock cycles at 1.35V. Hence if XMP claims CL30, try CL31 or CL32 (set manually). There comes a point of diminishing returns and stability is more important than outright speed.

In any event, outside benchmark apps or game FPS scores, you might not notice much difference running slightly looser timings. Some apps (DaVinci Resolve and Premiere Pro) gain very little from faster RAM on AMD CPUs. It's fractions of a %.

If you do run your DDR5 at 1.40V, you'll stress the RAM and the IMCs in the CPU, which may lead to slightly shorter life times. Err on the side of caution if you intend keeping the system for 5 years+ and accept marginally slower RAM overclocks. I'm running my DDR5 at 4800MT/s stock JEDEC on my 7950X.
