What the Core i7-5775C is
The Core i7-5775C is the top socketed Broadwell desktop part on LGA 1150. Intel released it in May 2015 with four cores and eight threads at 3.3 GHz base and 3.7 GHz turbo. Six megabytes of Smart Cache plus 128 MB of eDRAM feed cores and graphics. Processor base power is 65 W on 14 nm.
Hyper-Threading gives eight threads for encodes and virtual machines. The eDRAM acts as fast L4 for graphics and memory bound loops. The multiplier is unlocked, so Z97 owners can tune beyond stock where cooling allows. Stock turbo already leads Haswell i7 parts in graphics bound work.
Iris Pro Graphics 6200 from 300 MHz to 1150 MHz is the draw. It runs older games at 1080p and carries creation apps without a card. DDR3-1333 and 1600 over two channels feed the system. Buyers pick the 5775C to keep an LGA 1150 board while gaining the best integrated graphics Intel shipped on the socket.
Socket and motherboard compatibility
The 5775C fits LGA 1150 on Z97 and H97 with a 2015 BIOS that lists Broadwell C. Flash with a Haswell chip before swapping where the board shipped early. Z97 unlocks tuning, H97 covers stock clocks. The Socket vs chipset: what decides whether a CPU works guide explains the BIOS step.
Memory slots are DDR3 only. LGA 1151 boards never accept this chip. For used buys, confirm the seller board revision and BIOS version against the maker list before paying.
Memory, PCIe and cooling
DDR3-1333 and 1600 in two channels to 32 GB is the official ceiling. Dual channel pairs matter for Iris Pro performance. Sixteen gigabytes covers integrated graphics gaming with background tasks. The 128 MB eDRAM eases bandwidth limits in many titles.
PCIe 3.0 with 16 lanes from the CPU supports one card at full width. Most 5775C systems skip discrete graphics, since Iris Pro already leads the socket. A mid range card helps newer titles at higher settings.
Cooling follows the 75 mm LGA 1150 pattern in the CPU cooler compatibility by socket guide. A tower cooler handles 65 W with headroom for tuning. Watch eDRAM temperatures when raising voltage on Z97.
Upgrade paths
On the same socket the Intel Core i5-5675C drops to four threads and 4 MB of cache at the same 65 W for lower cost. The Intel Core i7-4790K offers Haswell speed to 4.4 GHz with weaker graphics for cheaper used builds. Both share boards where listed.
A platform move to Skylake needs a new board and DDR4. The 5775C is the end stop for LGA 1150 where threads plus graphics decide the build.
