MSI Radeon HD 7970 Lightning review -
Once the cooler is removed we can see the intriguing and complex PCB design. MSI used Military qualified III selected components. I And I know it is a heap of marketing, but make no mistake, these components follow MIL-STD-810G standards for duration. The board has CopperMOS chips for power delivery. Also seen on previous boards are the Hi-C Caps (aka Tantalum Capacitors).
New however are Golden Solid State Chokes, these actually are gold plated SSCs, supposedly for better heat dispersion and anti-corrosion purposes. Dr. Evils 'GOOOOOOOLD' continuously is in my mind now.
So the idea behind this is that solid ferrite chokes will oxidize over time and thus can cost performance. It also supposedly increases current handling by about 10%.
We spot a secondary new component on the PCB though, Dark Solid Capacitor -- aluminum core solid caps with a nickel-plated cover. This promises a longer lifespan as well as lower ESR (equivalent series resistance- lower temperature and a higher efficiency).
If we flip the cooler upside down we get a better idea of what is going on under the hood. Two 10 cm fans generate massive airflow for heat dissipation while remaining silent (at it's default clocks) The two form-in-one heat sinks improve cooling for memory and the power supply module as well ensure structural integrity. The heatpipes are all 8mm thick.
New is Dust Removal Technology. Fans are running in reverse for 30 seconds after booting to remove dust from the heat sinks.
In this review we take a peek at the MSI Radeon R9-280X TwinFrozr Gaming OC review. The smexy dark custom PCB has been armed with quality components, a dual-BIOS and their dual fan based TwiNFrozr series edition coolers. MSI factory overclocked the product and will try to get you as much value for money as they can.
MSI Radeon R9-270X Gaming review
In this review we take a peek at the MSI Radeon R9-270X Gaming edition. The product shares the same PCB as the HAWK and also comes with a TwinFrozr model IV based cooler.
MSI Radeon HD 7790 TurboDuo OC review
We test and review the MSI Radeon HD 7790 OC edition, also known under SKU code R7790-1GD5-OC incl FCAT Frametimes. The new graphics card is intended to boost a little more performance into entry-level gaming.
MSI Radeon HD 7770 Power Edition review
We review the MSI Radeon HD 7770 Power Edition. MSI recently released an updated Radeon HD 7770 1GHz edition with their own 1.1 GHz custom model. They use their own custom 4-layer PCB and equipped it with a dual cooling solution. I say dual here as you get an extra fan that you can pop onto the card for extra cooling. MSI also opened up the voltages for Aux, GPU and memory making the card very tweakable.
