I'll run some tests on the GTX 480 tonite Jon. GTX 580 861/2197 0007: 1390fps 0015: 1385fpsĪs you can see on 980Ti 0015 is faster, but forcing Gen 2 boosts both to about the same higher performance. XP64 + 364.72 default settings no lod, average of 3 runs 3DM01 Nature See results below.ġ50x28 (27 cache), 2100 DRAM, Xtreme Tweaking Enabled, FCLK 1GHz What kind of FPS do you expect on GTX480? Don't have one here but I tested with GTX580 and again with 980Ti but Gen 2 forced. There are a lot more tricks and tips in the full version of the guide that will definitely help you push your system further! In case the OC Guide source goes down, here's a mirrored version in the HWBOT cloud.Ĭan you guys help me reproduce this issue? Full settings and setup details please, preferably send me bios profile used as well. Some CPUs may have PCIe cold bug at around -150☌, so use the PCH PCIe slots for testing.įor more details, check out the OC Guide posted by Coolice in his dedicated Maximus VIII forum thread HERE. Most importantly, replace the TIM between the IHS and CPU die. Lower the BCLK frequency as low as possible to reduce the jitter on the PLL. To max out the CPU, you will need between 1.7V and 1.83V. For LN2 overclocking: the CPU core and cache now use the same voltage rail, so you cannot configure it independently. The highest available DRAM Ratio is DDR4-4133. Also note that the tRCD is tied to tRP and must be in sync, hence why there's only one option to control them. Setting both to 1.12V should be sufficient for DDR4-3500. For DRAM overclocking, the most important rails are VCCIO and VCCSA. 350 MHz BCLK should be pretty easy on air cooling. Level 6 PLL Bandwidth combined with 1.45V PLL Termination should give you decent margins. For BCLK overclocking: focus on the PLL Termination Voltage (or the linked CPU standby Voltage) and PLL Bandwidth. It also helps you understand the functionality of the USB ports near the PS2 connector, how to install Windows XP from a USB driver, how to get XTU working in Windows 7. The OC guide is very comprehensive and includes topics on BCLK, DRAM, Core/cache frequency, and LN2 overclocking. The thread also includes a link to an overclocking guide dedicated to the Maximus VIII series. That includes not only overclocking software like ROG Connect Plus, Turbo V, and MemTweakIT, but also handy tools to install XP from a USB drive and the AHCI XP driver. In a thread over at our dedicated Skylake Z170 subforum, Coolice from ROG has shared everything you need to get going with the Maximus VIII motherboard series.
