DDR3 overclocking problems
DDR3 overclocking problems
Hello...
I’m experiencing problems when overclocking my RAM. In simple terms, if I push the speed beyond what’s recommended—say from 1866 to 2100MHz—I’ll immediately encounter a boot loop after saving, which results in a failed OC. No memory error message appears; instead, it proceeds through Q codes up to around 50 and then restarts. To resolve this, either performing a CMOS reset or holding down the memory OK button seems effective. If I overclock from the stock 1866 setting to 2100MHz, it saves and boots normally. I’ve tested this with HCK and Intel Burn Test (10 passes).
I’ve used 1.650V, released timings ranging from 10-11-10-30 2T to 12-12-12-36 1T, and still encounter issues even when using LLC on RAM. I haven’t adjusted any other voltages.
Additionally, if I reach 2100MHz—which is stable at 11-11-11-33 1T—I notice a noticeable FPS boost of about 10 in most games. So, essentially, why does the motherboard keep looping? Are there any additional settings that could help?
Also worth mentioning: Occasionally, it displays Q code 55, requiring me to use one stick and re-seat it into every slot until it starts booting again, after which I can plug in the last stick.
Specs:
CPU - Xeon E3-1225v3
Motherboard - Asus Maximus Hero VII (latest BIOS)
RAM - Kingston HyperX Fury Black 1866 10-11-10-30 2T (stock)
GPU - R9 280 Dual-X
PSU - Delta TDPS - 650BB A 650W server class PSU
Storage - 1TB P300 Toshiba, 500GB WD Blue.
LOL. Are you really getting 10 FPS just by jumping from 1866 to 2100? That seems impressive. It's a big jump from 1333 to over 2133, but going from 1866 to that would usually be less noticeable. If you can maintain 1866 memory and hit 2133 stable with that kind of improvement, you've definitely won.
Yes, using BCLK 102.0 and 2200 really helps—gains less than before, fewer drops under 40, and I managed a 10fps boost even when keeping BCLK at 102.0. I feel like I've reached the limit, but DDR4 overclocks work better as I noticed.
