Topic: Any LTC miners that dynamically scale usage? (Read 843 times)
Definitely don't use d intensity on scrypt, unless you want a disgustingly low hashrate, i've had luck at about 15-17i
Thank you for the response. I can't find a version number anywhere in the GUIMiner files, but entering D under the intensity does work and it also brought my hashrate to the 20s (down from 600+). I've noticed intensity has no effect on gpu usage, doesn't matter what I set my intensity too, my gpu usage stays at 97-99%. I've also found that I have to bring the intensity to 12 or under to stop the slowdown of my pc and it's still very noticeable in videos. I think my problem stems largely from this. I'm wondering why the Bitcoin clients actually leverages usage and the LTC ones don't.
Going to try out CGMiner/CGWatcher combo tomorrow. Although I spend a lot of time at the computer, and since I have to drop the intensity so low to avoid the lag I'll have to look into how much that drops the profitability of LTC compared to BTC. If I can't find a solution, I think I'll end up changing to CGMiner/Watcher for BTC anyway.

GUIMiner Scrypt is just a front-end for cgminer or reaper. I'm not sure which one you're using, but if you're using cgminer you can set intensity to "d" for dynamic, regardless of whether or not you're doing scrypt or sha256 mining. I don't use GUIMiner but I would imagine it has somewhere to set this. Keep in mind that with cgminer, I believe sha256 has intensity range of -10 to 14 and scrypt has an intensity range of 0 to 20.
Also if you use cgminer you can use CGWatcher to monitor the miner (and as a GUI) and there is an option to raise intensity on all GPUs to a specific value when the computer is idle, and it will lower them back to their original settings when it is no longer idle. This allows you to get higher hashrates during idle than dynamic intensity would. There are many more features, you can check the thread for more info:

And because GUIMiner Scrypt is just launching cgminer hidden, you can still use CGWatcher with it... although it will communicate and control cgminer only and has no interaction with GUIMiner. I've heard others mention this works but haven't tested it myself. This is assuming you've set GUIMiner to use cgminer and not reaper.
Edit: I should point out that I don't use dynamic intensity, but as I was writing this I set one GPU to "D" while scrypt mining and cgminer lowered it to 8, causing hashrate to go from ~400Kh/s to 20Kh/s. Temperature was not a factor because it was down to < 60C by the time I noticed. So either I need to adjust something in my config or cgminer is setting dynamic intensity based on sha256 intensity range and not adjusting for scrypt's intensity range.... maybe. I can't say that for certain and I'm too tired at the moment to look more into it now. I'd still suggest using cgminer and setting a specific intensity value, then setting CGWatcher to raise intensity when the computer is idle.

I asked this in another subforum, but haven't gotten any answers so I'm going to post again here.
I'm trying to switch over to LTC mining with my 7950 and GUIMiner scrypt. I ran into a problem regarding the intensity settings, as I'm a very casual miner using the single 7950 in my main pc, I use my pc throughout the day and the miner slows it down dramatically. I notice my GPU usage stays locked in at 99%, with the BTC variant of GUIMiner it scales the usage dynamically. It's much more convenient then manually adjusting the intensity everytime I want to open something on my computer, are there any scrypt miners that do this?
