Dual Boot owners is your RAM running at 1066 Mhz and not 1600Mhz?

[Chris G]

Just running through my review of the Android ROM on my new Dual OS Hi12 (Liking it a lot btw) I noticed that the benchmarks are a good 10% or so slower than the Windows-only version I have. Normally there is always a difference between Windows and Android in 3Dmark, but when I dug a little deeper I see my bios has the ram set to 1066Mhz only.

DDR3 1066 Mhz

My Windows 10 first batch reports:

DDR3L 1600 Mhz

So we have a ram change to DDR3 from DDR3L (lower voltage) and the clock rate from 1600 to 1066. Funny thing is it only seems to lower performance around 5-10%. Can Dual OS owners please have a look and see if your memory is 1066Mhz or 1600Mhz? This could vary from batch to batch, maybe Chuwi ran out of 1.35v DDR3L ram and just 1.5v DDR3 instead? Not cool!

I’ve just set my ram speed to 1600mhz and everything seems fine! benchmarks have increased about 5% in Geekbench 3 and 10% in 3Dmark. More or less as I expected.

I looked and have 1066, how can change to 1600?

This is risky and I don’t recommend messing in the bios. But under the CPU settings, go to northbridge and memory config. Change frequency A from 1066 to 1600. Save and reboot, cross your fingers it works. I’m not responsible for any bricked units for this.

You’ll see a 5 to 10% boost in performance at the cost of battery life maybe, haven’t confirmed that yet. Maybe 5%to 10% battery life drop. Looks like the Windows only version might have the best battery life due to it running DDR3L ram which saves a little power.

“DIMM 1” option doesn’t shows up in BIOS/Northbridge/Memory config, didn’t find it elsewhere

Chipset/Northbridge/Memory Config/Frequency A selection (DIMM 1) change from [1067] to [1600] 

This may cause issues, change at your own risk. Not sure why Chuwi set it to 1067 when my first batch Windows model runs at 1600 Mhz. Whatever you do don’t mess with any other settings. It has no failsafe settings or rest and many options if changed could cause it to not boot requiring a reflash via USB programmer.

I see Frequency A and it’s [1068], I can change it to 1600 but nowwhere stand DIMM 1…. what BIOS version do you have?

[Rogus Mortem]

Chris G, I enter my Windows 10 only BIOS, and I can see a Southbridge but NO option to see the memory speed.

My Dual Boot Hi12 is also DDR3, 1066 MHz

[Mickey Y]

Can you advise how can I get onto that BIOS page from a reboot?

My hi12 dual os also came with 1066 Mhz, already set it to 1600 Mhz. No other side affects after that. Thanks.

[Chris G]

I’ve been running two days now at 1600 Mhz and no issues. Not sure why it was set to 1066 from the factory if my first model was 1600 Mhz.
