Hi guys i have almost exactly the same problem as zeuseng06. My dell studio xps 9000(435t) does not have CPU overclocking options available from the bios. I talked to a dell techie about this, and he said 9:30:21 PM 'name' It is better you do not do it. 9:30:32 PM 'name' It might hamper the performance. Now from what I have heard, overclocking should not hamper performance, unless voltage is increased. I know my computer is good enough already, but I want to overclock the CPU for the fun of it, even for only a couple hours. Specs: Studio XPS 9000 (435t) OS: Windows 7 Home Premium Mobo: Intel® X58(Tylersburg)/ ICH10R Processor: Core i7-920 2.66 Ghz (stock) Ram: 8 GB DDR3 1066 Mhz GPU: HD 5870 1GB (not sure of maker) @ 800Mhz GPU clock & 1200 Mhz memory clock Hard Drive: ST3750528AS (seagate barracuda) 750 GB 7200 RPM PSU: 475w stock (i have been told by dell this is fine for the 5870, even though the recommended PSU is higher. CD/DVD: 2 16x--nothing fancy Love to hear your opinions and options I have for overclocking. Thanks in advance.
