This statement asks whether a DDR3 RAM module fails to function properly in dual-channel mode when overclocked.
I recently purchased a new RAM stick to boost my memory from 8G to 16G. My original 8G was overclocked to 1960 and is running smoothly. However, the new 16G stick doesn’t work properly in dual-channel mode according to cpu-z. If I lower the frequency to 1866 or below, it functions correctly in dual-channel. Does this indicate that dual-channel overclocking isn’t possible? Why?
Hi, thank you for your message. The images you shared indicate the system is operating with the default BIOS settings, and no changes have been made. I’d like to be able to overclock the RAM while still using dual channel, as I previously adjusted both bus speed and multiplier for my FX8300. Maintaining performance at 1866 is challenging in this setup. Your board model is 990fx-ud3. I’m happy to assist you with this issue.
Can you post the same screenshots again when you do overclock them? Which slots are they in atm? Spd is said to be saying slots 1 & 2? Cpuz is reading dual channel, so it must be correct. Typically on four DIMM slot motherboards with two RAM sticks, slots 2 and 4, the second and fourth slots from the CPU. Unless I saw the wrong motherboard?
It seems the cpuz reads don't align with the number shown on the motherboard. The screenshot displays 1&2 but the actual display is 3&4 (blue). I adjusted to 1&2 (white) on the motherboard, and then cpuz now shows 3&4. It turns out the issue lies with the new stick. When I set the frequency to 1996, it failed to pass POST. Removing the new stick allows the old one to run, but the new one still doesn't pass POST unless used alone. It only works with the 1866 model. I'm uncertain about how it worked initially when I added the new stick and ran with old BIOS settings—it might have been due to multiple reboots while trying to diagnose the problem.
I'm sending the stick back to the seller already. I've ordered another from a more reliable seller. I'll check back later to see if the new one behaves normally, hoping it won't have any issues again. Thanks for your time and assistance.
Yes, I increased the voltage from 1.5 to 1.65 as requested. I also noticed some advice suggesting that raising the default voltage might cause the duel channel to fail before this point. However, it seems those warnings were incorrect now. It's probably related to the updated stick.
On my Ga-990-Fxa-ud3 r4 and the first revision of that mobo along with Amd's for Dual Channel mode 2x sticks, they should be in the 2nd and 4th slots from the CPU. According to your screenshots, they are not. Please adjust them to the correct positions and share updated CPU-z images.
