Ok so I just built a pc recently here are the specs: Windows 7 x64 ASUS SABERTOOTH Z77 LGA 1155 Intel Z77 HDMI SATA 6Gb/s USB 3.0 ATX Intel Motherboar Intel Core i5-3570K Ivy Bridge 3.4GHz (3.8GHz Turbo) LGA 1155 77W Quad-Core Desktop Processor Intel HD Graphics 4000 BX80637I53570K EVGA 015-P3-1480-KR GeForce GTX 480 (Fermi) 1536MB 384-bit GDDR5 PCI Express 2.0 x16 HDCP Ready SLI Support Video Card CORSAIR Professional Series HX750 (CMPSU-750HX) 750W ATX12V 2.3 / EPS12V 2.91 SLI Ready CrossFire Ready 80 PLUS SILVER Certified Modular Active PFC Power Supply Western Digital Caviar Black WD1002FAEX 1TB 7200 RPM 64MB Cache SATA 6.0Gb/s 3.5" Internal Hard Drive -Bare Drive NZXT Phantom PHAN-001RD Red Steel / Plastic Enthusiast ATX Full Tower Computer Case CORSAIR Vengeance 8GB (2 x 4GB) 240-Pin DDR3 SDRAM DDR3 1866 (PC3 15000) Desktop Memory Model CMZ8GX3M2A1866C9R ASUS Black 12X BD-ROM 16X DVD-ROM 48X CD-ROM SATA Internal Blu-ray Drive Model BC-12B1ST/BLK/B/AS - OEM $ So I noticed the cpu was hitting around 75 degrees C under load with the turbo turned on running at 3.8 ghz. So I turned off the turbo and now according to CPU-z the cpu is running at 1.6 ghz even though the only things I did were turning off the turbo. Also according to my temperature utility the cpu is at 1 degree C, so not sure whats happening there. So how do I increase the speed? I notice the dram speed is only 1333 when its rated for 1866 so I manually set it to 1866. I was reading online about this FSBRAM ratio stuff and got extremely confused so any help would be appreciated. I bought Cool master evo 212 hyper and am waiting for it to come in by mail but I still want to figure this issue out in case it happens in the future.
