***Updated for Claymore’s Zcash Miner V9.0***
***Update: Some variants (new ones) have an 8pin connector and Samsung memory, With mem clock up to 2050, you can expect 28.5mhs stable***
(This doesn’t really make a difference as the card doesnt overclock much, and power usage with ZEC is quite low, but still)
The all new MSI armor 470 4g just arrived in the mail today. So let’s review it !
Compared to the MSI GAMING X, the Armor has a smaller box, and is a smaller GPU too – All thanks to the less impressive heat sink. After running DDU and the latest AMD drivers, we are all ready to go.
Stock: The MSI Armor hashes away at 205 sol/s on Claymore’s v8.0 ZCash miner. Not bad, but what is impressive is that undervolted to -96mv on MSI afterburner, with stock 1230 Core Clock and 1750 memory clock (a bit overclocked – default is 1650/6600Mhz and Memory type is Hynix) we find ourselves with a voltage of 0.95v, and a GPU-Z power consumption of 72w. At the wall we are talking about a 105w total ! This card has an 82% ASIC quality, so there is possibility of bringing the voltage down even more, perhaps saving another 10w. If you fine tune yours, let us know !
BIOS Mod: A simple BIOS Mod through ATIWinFlash and PolarisBIOSeditor for the memory timings (1500 timings copy pasted to all higher values) nets us a 215 sol/s, with a slight core overclock (1250) for 105w total.
This card is cheaper, well built, smaller, backed by a 3 year warranty and is a solid GPU all around. Although it may be cheaper than the MSI GAMING X, there is a big price difference. It may be worthwhile to pick that one up on sale, but we are very impressed with the results so far. It also has an 8 pin power connector. A total performance of 215 sol/s with 105w at the wall usage (Gold PSU on 120v) means .49 watts used per sol/s performed (Or 2.05 sol/s per watt). Let us say this again, very good results. Good Show MSI.
NOTE: MSI confirmed these are Ball Bearing fans.
