Win7 should natively support USB 2.0, so disable it.ġ3) On-board audio - Disable. Raising bandwidth on the same architecture tends to require more buffering and latency, so it's not hard to see why USB 3 would be worse for mice.ġ2) eHCI hand-off - No reason to have this turned on for Win7 or higher. Virtualization and it's services tend to be resource heavy and no reason to have it on for a gaming PC.ġ0) 1394 controller - disable in order to reduce DPC latency unless you actually use it for some reason, probably 99% of people don't.ġ1) xHCI pre-boot driver / xHCI mode / xHCI hand-off - Long story short, you want as few USB controllers active at once as possible, and I would say mice perform objectively worse on USB 3 controllers. Traditionally a setting disabled by overclockers anyway.ĩ) Intel Virtualization Technology - disabled for any gaming PC obviously. Set it to Gen3 if you have an Ivy Bridge or higher CPU + a PCI-E 3.0 GPU, otherwise, use Gen2.Ĩ) Execute Disable Bit I disable it just because the odds of any negative effects outweigh the security benefit. Large difference between manual setting Vcore and auto on my Asus z77, but not as big on Gigabyte z77.ħ) PEG Gen3 Slot Configuration: I get better results by manually setting this instead of leaving it on auto. There's a noticeable difference between auto with power saving modes turned on and maximum phases on most motherboards.ĥ) Hyper Threading - If you disable HPET, you most likely do not want to run any virtual cores.Ħ) Vcore - Usually best to manually set Vcore since it seems to disable dynamic power features on some motherboards. I didn't have this issue on the Gigabyte board, so it seems to vary by motherboard.Ĥ) PWM Phase Control - Set this to max phases. On the Asus Z77 board, using a Steelseries firmware updater for a mouse seems to fail on Win8 if you disable "C3 State Report" and "C6 State Report". If you cannot tell the difference between changing settings like this in mouse response, you most likely have other latency bottlenecks.ģ) Turbo Boost/C-States/EIST/Thermal Monitor/Etc: You want to disable as many of these as possible because they bring a lot of lag. 100:100 with 1600mhz should obviously provide better results since it matches BCLK. This is also due to 133 vs 100 memory ratios. Some people will claim the difference is impossible to feel, but I assure you that it is, at least once you have eliminated all other sources of high latency in your system. The ram I have installed can do 2133mhz 11-11-11-28, but 1600mhz 7-8-7-24 provides a much better feeling mouse response. The only problem is, high bandwidth and the resulting high latency is not conducive to a positive game play experience. Disable spread spectrum to try and fix the last part if you can.Ģ) Memory Strap / Memory Multiplier: Since this is an overclocking website, many people love to crank this number as high as it can go. This is the closest to a flat 100 I can get on this board due to spread spectrum being a hidden setting. Manually setting it to 100.01 gets me 100.03. Leaving BCLK at AUTO, or manually setting it to 100.00 gets you an unwanted number like 100.1 on the UD5H. The Gigabyte z77 UD5H is one example of this. Many board makers have BCLK overclocking features built into their BIOS to try and cheat at benchmarks for hardware review sites. The closest you can get this to 100.00, the better. ![]() This setting will probably be very subjective to a lot of people depending on what mouse, mouse settings, and surface you use, but my experience so far is that legacy tends to be better with a more classic mouse movement.ġ) BCLK: you want this to be 100.00, not 100 point random number. UEFI vs Legacy boot Legacy with CSM enabled tends to give me a more traditional mouse movement feel, while the times I've tested UEFI with CSM off, it gave me a more floaty mouse cursor type movement.
