Why is my ram timings incorrect?
Why is my ram timings incorrect?
Starters.. I have Corsair Vengeance 1600MHz RAM (2x4GB).
When I enable auto in BIOS it shows 1333MHz even though my RAM is 1600.
CPU-Z lists timings as
11
11
11
28
In the memory tab but in the speed tab it says
Case# latency 6.0 7.0 9.0 9.0
RAS to case# 6 7 9 9
RAS precharge 6 7 9 9
TRC 22 26 33 33
Command rate 2T
Looks like this is probably normal, maybe I'm misreading or missing something.
Navigate to BIOS/Ai Tweaker/Dram Timing Control and adjust the necessary timing values for CAS # Latency, RAS# to CAS# Delay, RAS# PRE Time, and RAS# ACT Time. Keep the rest parameters set to Auto. The Dram Command Rate might need to be configured at 2T, though this could result in a minor performance decrease. Only modify it if you encounter issues with the 1T setting.
The advertised speed of the RAM is its highest guaranteed rate. The RAM must operate at that speed or slower. However, the motherboard determines the actual speed. If your motherboard doesn’t support the higher frequency, it will run at the maximum supported by the board. It seems your motherboard only allows up to 1333Mhz, which explains why your 1600MHz RAM is not reaching its full potential.
Good response, but according to the manufacturer's site it appears the RAM I'm using is compatible with my board, so I expect it supports 1600. On a side note, I adjusted the MHz to 1600 as it's the default speed, and now the BIOS shows I'm running at 1600. I'm just not sure about the timings in CPU-Z.
Here are the screenshots showing what both tabs display.
The XMP-1600 column on the SPD tab indicates the profile is compatible with RAM sticks. The actual speed depends on whether your motherboard/BIOS supports it. If your BIOS allows XMP profiles, you must enable them in the BIOS settings to achieve higher speeds. Otherwise, with standard settings, you'll be limited to 1333MHz.
You might achieve better speeds if your BIOS permits manual timing and voltage adjustments, though you should verify your cooling system can manage increased heat. Using higher voltages could also risk system instability.
I've adjusted the ram to 1600, but I'm unsure if there are other steps I should take since I haven't modified the timings even though I can change them. It's possible the timing settings were already optimized for higher MHz. Did I miss anything? I thought timing changes usually affect performance at higher frequencies.
You might want to adjust the RAM latency settings. Right now you're at 1600mhz with specific timings. Consider trying 1600mhz with 10-10-10-26 or even 1600mhz with 9-9-9-24 (this could need a command rate of 2T).
Yes! That's what I need to know as it mentions the number 1600 9-9-9-24 on the site. How can I proceed with that?
