Bfgminer Download Windows

By default, BFGMiner will NOT mine on any GPUs unless in scrypt mode. If you wish to use your GPU to mine SHA256d (generally not a good idea), you can explicitly enable it with the -S opencl:auto option.
To start scrypt mining with bfgminer and GPUs, use the --scrypt and -S opencl:auto options, but keep in mind that there are several other parameters to consider. See README.scrypt for additional details about scrypt mining configuration and optimization with GPUs.
CGMiner has removed GPU support, but BFGMiner has not. You can use an older version of CGMiner (i.e., v3.7.2) or GUIMiner or RPCMiner.A GPU is still useful for mining alternate coins such as litecoin, especially if you have a high-end AMD card.
i was wondering has anyone been able to get the 7900 gs agp video card to work with Windows 98. i know there is unofficial drivers for it, but i am curious if someone has actually gotten that card to work in a Windows 98 environment without issues
First issue is not due to 7 series but is 82.69 problem. It is "shutdown bug". This bug is fully fixed many years ago, Google will help. It is necessary just to replace two or three files in 82.69 from another detonator (AFAIK some 77.XX version).
Second issue is due with not only GF7 but ALL nVidia models over GeForce 4600 AGP4X. It is 3D running (in some few games) in window-mode as default. And AFAIK this problem is solved too. Need to find. Anyway you can always switch to full screen mode manually.
I strongly advise against using anything newer than a 6800 in win98. Even the 6800 has issues - especially if it's one of the late 512MB DDR2 models. 7xxx drivers are buggy and cause lots of compatibility and performance issues in win98, not to mention BSODs and other weird happenings.
OK, and there is no logic. Why exactly against newer than 6800? A problem with 512 mb? I thought everybody knows it and even didn't say about it. Of course it is necessary to use 256 mb only versions, it's like 2x2=4 for Win98. And 6 or 7 generation doesn't matter here!
If you could say that "strongly against newer than FX 5950GT" I would understand it because it is latest and fastest native AGP chip.
But you said "strogly against newer than 6800" and I don't understand it, sorry. Some possible issues which may be typical (by the way I don't know them) for 7800/7900GS/7950GT will be the same for 6800GS/GT/Ultra too and nothing more. Therefore if any user is satisfied with 6800 he will be excited with 7900. I say again: unofficial version 82.69 is working wonderfully.
Yeah, sorry! PCIe bridge is soldered on the NV40 pcb for pci-e cards. Anyway we need old nV card and old driver just about 4xxx-6xxx. And even in this case sometimes we can find some errors like incorrect or impossible work DOS-screens etc. Therefore I think that too much severe critique of the 7 series is not right. With 256 memory size it works flawlessly.
In case anyone is still looking for Geforce 7xxx W9x drivers, here's the link to download the BFG unofficial ones. I spent about an hour in the Internet Archive before I could find an archived page that wasn't broken.
(edit) there's also which is supposedly an user-modded version of 82.69 with the 7xxx and 8xxx series added in manually. Info in and
I haven't yet tried either of the above (the card is still in the mail)
1. video memory needs to be cached into system ram in win98. That causes problems with video cards that have over 256MB of ram. As you already know, win98 does not support more then 512mb of ram, and win98se supports up to 1GB. Using a 512MB vram card with 512mb of ram will causes windows98 to not start - error is "insufficient memory to run windows". Using 1GB of ram fixes the issue, but I've experienced general instability in win98se, with loads of programs and games performing "illegal operations".
2. the 7xxx series was never intended for win98. Drivers are more or less unfinished and unstable. Use at your own risk. As such, many games will not run correctly. Most openGL titles except for GLQuake work well, I found problems with lots of d3d games.
I found numerous issues with games running a 7 series card under win98 (tested with 7900 and 7600 AGP) among witch crashes to desktop, system freezes and BSODs. Also some older games are not a fan of the new cards. Dungeon Keeper II runs on the 7600 AGP, but has the black screen bug on the 7900. Black and white displays artifacts ingame. This is a driver issue, as the same artifacts are present on the 6800 - BUT you can use older drivers with the 6800, and it will work fine in B&W - the problem is the working drivers do not support 7 series cards. Sacrifice freezes after 5 mins of gameplay on both 7600 and 7900 agp cards. Again, a driver issue. Same thing happens on the 6800 with the same drivers, and again, works fine with older drivers witch do not support the 7 series. Unreal gold also freezes at one point during gameplay.
The problem is not with the cards themselves, but with the drivers. I never said the cards don't work, but getting them to work is a pain in the ass and even after all the work most of my favorite games won't work well on the card + 8x.xx drivers I got the card working with.
If you want to prove the 7 series cards run well in win98, show us what drivers you're using. I really really hope I'm wrong about the cards acting up in win98, and my experience is based on me fucking something up, but i have yet to be proved otherwise. A link to the drivers you used to get it working perfectly as well as the system you used it on would be wonderfull.
So I am looking at a build with a 925XE chipset and single core prescott EE P4. Trying to do a dual boot XP / 98SE. The board I am pondering has PCI and PCI-E only. Thank you for the archival links above. Will they work on PCI-E versions or only AGP? I've not bought a video card yet, but would like to make the best selection for both intended purposes. Was this debate ever settled about 7800 or 7900 working well on 98SE?
I will say will be not imposible but to hard or to stress to get that hardware run on win98se , i try many diferent ways to get 7900gt working but the drivers not install properly at the end of any attemps , allways finalize with diferent errors , exclamation signs on device manager, windows boot problems etc...
