It can be overclocked. The official website has software for overclocking. However, this top class graphics card has heat and stability as its major premise. It does not need overclocking, and it is not too slow.
It depends on what motherboard you use. Gigabyte can do it.In addition, after entering the bios, the numeric keypad is turned off by default, and numbers can be entered only after being turned on. My E5400 can easily change the main frequency from 200 to 240, that is, more than 20%, without adding voltage,
The only way is to change the board of 2140 Pioneer hard. There is no option to adjust the external frequency. Choosing D2000 is to choose not to overclock
200 266 333 400 This is the memory frequency,.You didn't find the right setting item. It should be the 200M item. It's OK to go up to 230. My e5300 can go up to more than 240, but the temperature is too high. I only go up to 230
The problem of overclocking is relatively complex. Some mainboards have overclocking protection function, which requires a complete power failure and BIOS clearing to restore to normal.Some mainboards have overclocking nodes. When the frequency is set to a certain value, overclocking is not allowed. It must be lower or higher than this value to be normal.Other motherboards have rich overclocking options, but as long as the frequency is higher than a certain value, all settings will automatically restore to the default.If these conditions do not match, the mainboard may be faulty and can only be sent for repair.
