2 Prologue to Hawk series In 2009 MSI introduced the Lightning VGA series. Lightning is a custom build PCB combined with a high-end GPU made to shatter world records. MSI N275GTX Lightning continues to hold the record of world s fastest single nvidia based VGA card! World Records Cooling 3D Mark Vantage MSI N275GTX Lightning LN2 P20460 GTX285 World OC record LN2 P17322 GTX280 World OC record LN2 P17665 GTX260 World OC record LN2 P18822 GTX275 reference design AIR P13541 MSI Hawk series will bring the features and overclocking madness of Lightning series to a mainstream level GPU. MSI Hawk series is an Overclocker s essential! Source: MSI GTX 275 Lightning Shatters World Records on LN2 Confidential Page 2

3 Key feature of MSI R5770 Hawk 7+1 phase PWM design World s first HD 5770 has 7+1 phase PWM for better overclocking capability 7 phase PWM for GPU on Hawk provides 100% more current compared to 4 phase PWM on reference HD Over voltage function of GPU Use afterburner to overclock HAWK, and performance is up to 20%. GPU Voltage can be increased up to 1.35V Twin Frozr II Thermal Design Dual PWM fans and triple heatpipes. Temperature is 13 lower than reference cooling design. Military Class Components Model Core Clock Memory Clock Output Hi-C Cap provides more precise GPU voltage and has better stability. SSC (Solid State Chock) for No Buzz noise. All Solid CAP for longer lifespan. R5770 Hawk 875MHz 4800MHz DisplayPort + HDMI + DVI-I Confidential Page 3

4 7+1 Phase PWM Design Supports higher current Has better overclocking capability Shares more loading compared to 3+1 Phase PWM design 57.2 % better! Confidential Page 4

5 Over Voltage function of GPU Default GPU voltage of HD 5770: 1.15v Maximum GPU voltage of R5770 Hawk: 1.35v 20% Higher! 16.4% Higher! R5770 Hawk OC: 1020/5600 Confidential Page 5

6 MSI Afterburner All must have features for overclockers! Afterburner Interface Industry leading VGA overclocking & monitor utility Co-developed by MSI & Rivatuner Support both NVIDIA & ATI graphics cards GPU voltage adjustment 5 customized profile settings. (2D/3D profile auto switch) Advanced Fan control. SLI & CFX Mode Support. 2D/3D Profile Switch Advanced Fan Control Multi GPU Control Afterburner website: MSI Afterburner supports R5770 Hawk to adjust voltage of GPU & 4 x CFX mode!
