Undervolting Gigabyte R9 bios self. Next time, dump the ROM for each card separately. I will try this when I get home. Thank you good sir. Become gv r927oc 2gd litecoin charts Redditor and subscribe to one of thousands of communities. All I did was saved the stock rom, opened it with VBE7, changed 0 in the "1- Performance" section to wassaved and re-flashed.

Just so you know the first two cards are asus and the others are gigabyte. Thanks again, you earned it! I have oc guru installed on fresh win8. The problem does not show up during simple EFI framebuffer mode.

No, i gv r927oc 2gd litecoin charts use mem litecoin hashrate and stable. I am wondering if anyone has the stock Hynix rom for charts cards that they could send my roc so i can try that. This did the trick for me. IR redesigned the chip a little bit and now they selling it under IRA gv r927oc 2gd litecoin charts.

All I need is for the vcore to gv r927oc 2gd litecoin charts lowered to say or bios file 2gd for all your help with these cards. I've found the non-X, so far, to be equivalent in quality and stability, they just differ in heatsink and fan noise. About your settings, are you really running at mem or is that a typo?

What's the gv r927oc 2gd litecoin charts on yours? I'm getting solid and and stable with my settings. No, i really use mem my hashrate and stable. I like my cards, actually. It could be my overclock, duh!

Miner kicks in within seconds of X loading. As an update, the undervolt definitely helped with the temps. I think the undervolt on this card messes with the cgminer temps though. I have the Gigabyte R9 's and I've undervolted to on 0.

I have thread-concurrencygpu-engine and gpu-memclock and the cards are running at kh so far. Check this utility out: If that doesn't work try this: Thanks for trying to help, but neither of these tools work.

Software undervolt doesn't work in linux, the drivers don't support it. The reason why the name of the VRM chip was completely changed is, that the company who designed the original CHLx Chil Semiconductor was aquired by another chip maker, International Rectifier back in IR redesigned the chip a little bit and now they selling it under IRA name. Hello, I'm still interested in undervolting. Did you find another tool to use? I'm using a windows system. Even the voltage monitoring is greyed out.

Has anyone used software voltage control on windows with these cards?? Thanks for the tip. It did not work following those instructions or replacing the name with IRA. Hey, i am also interested in this! Can you please post your modified BIOS? I uploaded the files to my drop box, Here.

The first and last roms for some reason are larger than the rest, and these two cards hash lower then my other cards too. I also noted that at the win98 CMD prompt the 2 cards had different checksum's whatever that is and they were 0x2A72 and 0X2B80 for the first and last one, while all the other cards were 0xFC Any help would be appreciated, and thanks a lot! Jeez I havent been able to get my modded bios working all week. Would you mind modding 1 for me.

All my cards have the same bios version and are the same file size. All I need is for the vcore to be lowered to say or bios file Thanks for all your help with these cards. I have one of these that I would love getting undervolted, here's the ROM:. Damnnnnnnnn that's why I've had a hard time with this card. Any tools in Linux available for this?

Use gv r927oc 2gd litecoin charts to extract the rom image and make a backup, then create a copy and modify the voltage in the copy. How stable is it? I tried vertcoin bamt and would get some odd behavior. I switched back to 1. What are your memcore numbers? I believe I have the same cards these are the ones I boughtbut I don't know much about undervolting or flashing yet. I got the gv r927oc 2gd litecoin charts cards. They both use the same ROM.

Here's the original dump: I seem to have fixed my issue by tweaking another fw for a similar card from a different manufacturer that had both memory types written into it. Submit a new link.

It is difficult to find them in stock. It did not work following those instructions or replacing the name with IRA. I am now hashing again. Considering I could of ordered xfx r9 DD's yesterday but passed since I had the tri-x's ordered. Want to add to the discussion? Ozymandias , Feb 8, They are profitable with a free use of electricity. The demand of these has far outpaced the demand that was thought to be adequate.

Thank you good sir. A detailed description of installation and 2gd is available here club. The energy consumption is up to watts. Thanks a litecoin for all this. There are several main mining programs - bfgminer, ufasoft minerdiablo miner, calculator, guiminer, cgminer. Roc did not work following those instructions or replacing the name with IRA. Feb 6, I can't believe what they are selling for now.

Feb 8, A tangent, my apologies. Ok, these are mostly theoretical questions-- not rhetorical. Or, in other words, how long does it take to go from raw silicon and other semiconductor materials to wafer doping and etching to GPU assembly to PCB etching to soldering to final board assembly then to packaging and shipping for one card?

At which point in the production chain is lagging behind on supply? If TSMC is holding back production of the graphics cards, what is causing the slowdown or lag behind production? In other words, when can we expect both supply and original prices return to normalcy? They will snatch up cards and keep snatching until coin mining is no longer profitable. As if they care how many they own, as long as the price is right!

Prices will never come down. R9 series will launch later this year and skyrocket to the same prices over night. TaintedSquirrel , Feb 8, Well first they would have to meet demand at current levels. So first they have to have enough cards so people don't have to wait.

Then maybe they could lower prices Let's just face it, prices are going to stay what they are for a long while. And now that Nvidia sees what is happening don't be surprised if their cards start doing the same thing in the next couple of generations.

Nobody is going to turn down a few hundred in extra profits Cobra , Feb 8, Ozymandias , Feb 8, If someone is on the market for a new graphics card, AMD or Nvidia, if they know the card will pay for itself via mining, they're more likely to buy AMD.

Use gpu-z to extract the rom image and make a backup, then create a copy and modify the voltage in the copy. How stable is it? I tried vertcoin bamt and would get some odd behavior. I switched back to 1. What are your memcore numbers? I believe I have the same cards these are the ones I bought , but I don't know much about undervolting or flashing yet.

I got the same cards. They both use the same ROM. Here's the original dump: Next time, dump the ROM for each card separately.

The further price growth is possible due to the growing popularity of mining. The newest graphics cards by AMD. For calculating the tasks, 2 cores are used in them. So, when installing 1 card in the farm, it will be equal to 2 and there, where 6 graphics cards could be installed, no more than 3 such monsters would be installed. The largest ones in size. In some online stores it may reach 50, Due to such characteristics, the payback of the farm with such graphics cards will be long.

They are profitable with a free use of electricity. Another popular series among miners. The average cost is RUR. Are not the most profitable ones. The price is RUR. The price increased recently due to a fast growth of demand for them. The third most popular series after r9 and According to the users of these cards, their cooling system is worse than by younger series, which is why when building a farm with such cards, it is necessary to construct a good cooling system. The mining with the use of the CPU capacities is essential only on some crypto currencies where the CPU mining is possible.

The main such currency is QuarkCoin. Here, AMD loses in capacity: This is why such mining is not profitable. Here are the capacities of smartphones, cloud servers with CPU capacities and other low-powered equipment. The information is presented for your guidance as the mining on such component is pointless. According to the above-stated information, we can make the conclusion about the most profitable way of the scrypt mining at this moment.

SHA and Scrypt mining Edit Due to popularity growth of Bitcoin at the end of , the mining difficulty has increased for many times. R9 x To date, the majority of miners consider the golden mean constructing farms on these video adapters. R9 x Also suit for constructing farms on their base. Comparison of graphics cards Edit Below, there are some statistic data about the performance of various mining equipment.

Y - blocked, N — not blocked, U — unblocked by the reflash,? Sapphire MB 1,1 cgminer 3. F62 firmware , 1. The information in the table is sorted by the capacity ascending. Graphics cards by AMD are nowadays the most powerful ones in the mining sphere.

Recently, the nVidia Company announced the release of the new graphics card that can compete with AMD. The most flexible in settings and informative mining program is CGminer.

It also has a modification for various hashing algorithms. CPU mining can be set on the cloud servers that provide capacities of some number of processors. Retrieved from " https: Read in another language.
