Hi guys and girls,
Strange issue here. Both HWInfo and CPU-Z shows the incorrect BCLK/DRAM Frequency.
Before anyone says anything, I understand that most monitoring software only states half the effective memory.
Rig:
ASUS x99 Deluxe
i7-5820k
Corsair HX1000i PSU
Geforce GTX 1080
Crucial Ballistix Sport DDR4 2400 4 x 4gb (quad channel)
The problem is with the ratio and memory multi.
BLCK is manually set to 100 in BIOS, BCLK/DRAM Frequency manually set to 100:100.
So HWInfo should show a DRAM clock of 1200mhz, and a memory reference clock of 100mhz or thereabouts.
But it doesn't. It shows the correct base frequency (1200), but the multi is x24, indicating that my BCLK is incorrectly set at 50mhz.
I have confirmed this in CPU-Z, which shows the same clock with the ratio of 1:24.
HWInfo:
Current system memory clock: 1200mhz (all good)
Current system memory clock ratio: 24
Current system memory clock: 50.0mhz
Latency settings are fine.
I have confirmed BCLK and ratio are manually 100 and 100:100 respectively in the BIOS.
And I have massive latency issues in AIDA testing and visibly.
I have reflashed the latest BIOS, cleared CMOS, reinstalled Windows to confirm that none of them were the cause. The RAM has also passed MemTest86, full runs at both 2400 and 2666, so it's not the issue.
I have also tried running the RAM at BCLK/DRAM Frequency 100:133, in which CPU-Z changes my ratio to 1:18 which still indicates that my BCLK is at half (66.67mhz).
Can someone please advise. Is this because I'm running quad channel? Do single and dual setups show the full BCLK/system memory clock while quad channel only displays half (i.e. 50mhz)?
Martin, are you able to confirm whether quad channel MRC is reported differently to single/dual? Love your work too mate.
Thank all for your input.
