Overclocking Nvidia GeForce GTX 750 Ti Maxwell for Mining

18, Feb 2014

nvidia-geforce-gtx-750-ti-maxwell-oc-mining

We’ve been playing a lot today with the new Nvidia GeForce GTX 750 Ti graphics card based on the new Maxwell architecture from Nvidia, trying to overclock it as much as possible in order to get the best possible Scrypt mining hashrate out of the card using CUDAminer. The GTX 750 Ti card we have is a reference design one and it is a bit limited in terms of overclocking options, though we have tried pushing it to the maximum possible values to see what hashrate we can squeeze from the new GPU. We have already gotten about 265 KH/s with the default settings of the card, but overclocking it has increased the performance up to almost 300 KH/s whill still in the 60W power consumption (maintained by the power limiter of the graphics card).

As you can see from the screenshot above our reference design board does not allow user control of the voltage and does not provide an option to increase the power limiter past the default value of 100%. This is done due to the fact that the TDP of the card is set at 60W and the board has no additional PCI-E power connector available, so it needs to fit in the 75W maximum power that the PCI-Express slot can provide to the card by specifications. We have pushed the GPU to +135 MHz which is the maximum value that EVGA Precision and MSI Afterburner give us available and the video memory to +650 MHz as the maximum stable value resulting in about 297 KH/s hasrate that can be squeezed out of the 60W TDP (100% power limiter).

What we have to do now is look for alternative boards that do not follow the Nvidia reference design and that do have more headroom for overclocking – PCI-E power connector and the ability to increase the GPU voltage along with the option for more than 100% for the power limiter. This can give us the ability to squeeze some more KH/s from the GTX 750 Ti as the GPU is clearly handling overclocking very well and can most likely handle even higher clocks without increasing too much the power consumption. As you can see with the fan of the very small and basic stock cooler at 100% the operating temperature of the GPU is just about 54 degrees Celsius, so with a better cooler higher clocks should not be a problem at all… after all 60W is something that is not hard to cool at all nowadays.

We have just tried the card on a x16 PCI-E extender and there seems to be a problem with the normal operation. The fact that the card needs 60W over the PCI-E slot and has not external power over PCI-E power connector can cause problems if you wish to use extenders that do not have molex power connectors. So if you plan on using GTX 750 Ti with extenders it will be a wise idea to go for cards that do come with PCI-E 6-pin power connector on them to save some trouble. The x16 PCI-E extender we have tried works just fine with a Radeon R9 280X card, so the problem is not in the extender.

Download vertminer 0.5.3 VertCoin GPU Miner for Windows

vertminer-0-5-3-windows

Vertcoin (VTC) mining with GPU requires a special miner called vertminer that is essentially a modified version of cgminer 3.7.2. The latest version of verminer 0.5.3 is designed to be used for mining VTC on AMD-based graphic processors. Note that the hashrate you will get by mining VertCoin with this modified mining client will be lower than what you get wen mining traditional scrypt based crypto coins. VertCoin (VTC) uses Scrypt-Adaptive-Nfactor algorithm and not just the standard scrypt algorithm that makes it ASIC proof and harder to mine, but also making it another very interesting alternative to most other alt crypto currencies that are essentially cloning BTC or LTC by using either SHA-256 or Scrypt algorithm. What is important to know is that you will not be able to mine VertCoin (VTC) with the standard cgminer, you need to use this modified version. Below you can find a download link to the latest vertminer 0.5.3 for windows.

On the Hunt for the Most Profitable Crypto Coins

CoinWarz is another service where you can keep track of the profitability of the various alternative crypto coins in order to hunt for the most profitable one at the moment to get the best out of your hashrate, especially if you do not have a lot of it available. This service provides a mining and profit calculator that works with the supported cryptos, so you get actual profitability data based on your hashrate and power consumption for each crypto coin. It also checks and reports the best exchange rate at which exchange as this is also an important part for calculating the crypto profitability correctly. The list of alternative cryptos includes both scrypt-based ones as well as sha-256, so this service is useful not only for GPU miners, but also for ASIC miners that are interested in making some more extra profit by mining alternative cryptos instead of LTC or BTC directly.

Have in mind though that the profitability of alternative crypto currencies is very dynamic and if you start mining a crypto with very high profitability due to low network hasrate and difficulty, the situation can quickly change is a lot of other miners also follow in your footsteps. So it is important to be fast in finding the right pool and starting to mine the highest profitability crypto in order to maximize your profit – you can check our alternative crypto “cheat sheet” information that we have available here to help you in that. For example at the moment the most profitable alternative scrypt crypto is 42 (42), followed by DigiByte (DGB) and Globalcoin (GLB). The situation with SHA-256 alternative cryptos shows that eMArk (DEM) is the most profitable, followed by Betacoin (BET) and OpenSourcecoin (OSC).
