MSI Radeon HD 7770 OC edition review -
So, pictures then, below you can see the MSI Radeon HD 7770 OC edition. Below you can see packaging and bundle. Included with all cards will be manual and a demo and driver CD, power converters and an monitor connector converters to get your multi-monitor freak on.
The 1.5 Billion transistor encounting 28nm Cape Verde based core is tied to a whopping 1GB memory -- which is a lot for Entry level products.
The reference 7770 cards are clocked at a 1000 MHz core frequency and the GDDR5 memory runs at 4.5 Gbps (effective data rate as GDDR5 has a quad data-rate, so effectively that quadruples that number) the memory bus is 128-bit though. The MSI OC edition card is clocked at 1020 MHz btw.
Here we can see the backside, the card will fit pretty much any chassis. Gain we see the backside of the PCB showing a very non-complex design, that's typically a very good sign.
Connectivity wise the output connectors will vary per brand. MSI equips the card with two display port connectors (mini), HDMI and a DVI connector.
The reference R7770 has a power consumption of roughly 80 Watts. The boards overall power consumption from idle to load is excellent really. Expect an idle wattage of roughly 10 Watt and when the monitor goes into power save mode, the card throttles down even lower towards 3 watt.
Here we can also see the cooler a bit better. Heatpipe based with two fans blowing over the aluminum heatsink.
You will need to hook the 7770 up to your power supply with a 6-pin PCIe PEG connector. We recommend a 500 power supply to start with, with one card of course. You could opt to go with two cards in crossfire mode as there is one Crossfire connector available on the card.
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.
