What is going on in yac.coinmine.pl !!

No any information... and miners are hashing just air?

Not to mention the efficiency of the psu will also have a impact on the system as a whole. 25W from a R7 240 is nice, something tells me they will outshine the 750ti when NF gets even higher as you can get them in 4Gb versions compared to the 750ti with only 2Gb.

Spot on about the power supply. I prefer to use the evga supernova 650G (gold efficiency power supply) on my rigs. Another builder used generic grey box PS on his and his efficiency isn't quite as good as mine - I think it may even be as high as 10W per card difference. Do I think I saved the $40-50 difference between to different units in a year? My math tells me it's about $10 per card per year cheaper at $.125 per KWH, so actually, I do. Now, if I am done with a rig for a reason, I have a premium PS left over for some other project or for sale, and it's got fairly low utilization because that rig uses well under 50% of the capacity of that PSU.

Rule #1: Don't cut corners on the power supply unit: Gold Plus or above.

I learned that lesson the hard way... Sad

Tbh i have no idea as i dont have the gear to measure it on my test setup, i know the 750ti is TDP locked @ 38,5watts i have 2 of thees just for testing purpose. One of them is flashed to 65,5watts TDP while the other one is stock TDP. Crypto mining blog already did some testing on 750ti http://cryptomining-blog.com/tag/gtx-750-ti-power-consumption/ http://cryptomining-blog.com/3036-power-usage-of-geforce-gtx-750-ti-with-various-crypto-algorithms/
The r9 280x https://litecoin.info/Mining_hardware_comparison or simply google r9 280x dc2t 3gd5 mining power consumption there will be plenty of reading on people oc and undervolting thoes cards.

Hope that helped abit

Unfortunately, unless they are specifically mining at NF=16, there's not really a great gauge. Because of the memory requirements of the coin, not all of the shaders can be utilized, so the card is running at a portion of it's full capabilities. The best way to tell is to plug your system into a kill-a-watt or similar device and take an idle reading of the watts, and then take a reading while running various mining configurations. You may find that a slightly lower hashrate (perhaps from a lower lookup-gap) yields a higher hash-per-watt, and that may be of interest to some people. I haven't taken wattage readings since NF=14, but I was measuring about 25W per R7 240 at that time, and ~32W per R7 250.

That setting should give around 0,22-0,23Khs. core clock is +155 and memory clock is +475 in msi afterburner.

That's too low. You can get 1200 H/s from your card -> http://www.whattomine.com/

Default(start) values are adapted for 1000 kh/s of Scrypt(280x). (copyed from whattomine)

A 750ti does roughly 260Khs scrypt can be bumped to about 330Khs with oc and the bios mod for more power. 1,2Khs was maybe true when nf was 15 but not at nf 16. If you know a config for a 750ti that does 1,2Khs at nf 16 then by all means please post it.

1000 H/s for a 280x and 1200 H/s for a 750ti, those are the default values for Chacha Nf16. Are you saying that both are too high?

It calculates it after the scrypt hash rate, the default rate they put in is 1000Khs. Try changing the scrypt hash rate and see what happens in the chacha hash rate tab. My r9 280x runs 760Khs in scrypt mode but only 255Hs when mining YAC, my 750ti run 336Khs in scrypt mode and 240Hs mining YAC, both speeds are at current N factor 16. Basicaly its just gives you a rough estimate of hash rate for the diffrent algo when you put in the scrypt hash rate.

Could you please tell us the power usage on your cards to get those 255 H/s (R9 280x) and 240 H/s(750Ti)? Thank you!

Has anyone else been having connection issues with yac.m-s-t.org? I looked at my 'unconfirmed balance' (ie coins mined in the last 520 blocks) and it was much lower then normal. I looked at a few of the miners, and they all have some kind timeout/connection error.

What performance can i get with dual processor intel xeon E5 2670 v3 (24c 48t) [email protected] GHz? Grin

~375 H/S (for 240 watts)
roughly the same hash rate as a 25 watt R7 240 4GB card...

So GPU is still more efficient? When (what N) will CPU be more efficient?

It's more efficient than _THAT_ CPU by a lot. That Xeon's a power sucking beast that does not support the latest CPU extenstions. The newest low power i7's are going to be the best bet for CPU efficiency and hashrate. I have an i7 3610QM in a laptop that's around 140 H/sec with a load draw total of 48W, and 24W at idle = 24W of CPU. It's not quite up there with GPU's, but about 40% the hash rate for the same wattage. Newer i7's and desktop chips may perform better. When I think about it, I'll test the newer i7 4800MQ to see if there's much difference.

with 280x its more tricky, gotta find that buffer sweet spot, this may not work for you out of the box:

-nfmin 4 --nfmax 30 --starttime 1367991200 -R 2500 -g 1 -w 128 --buffer-size 2590 --lookup-gap 16

or simply try those from UTC site for nf16:
http://www.ultracoin.net/configgen_raw.html

Using cgwatcher, so no batch file.

yeah, this is working. thank. now will try to push the speed.

Hey,

Sadly 280x are wrong, not sure why... Will update it soon(Managed to get 290hash/s with stock 280x)

Anyway I managed to get even better results from 750ti - reports 0,38 khash/s:
cudaminer.exe -a scrypt-jane:YAC -H 2 -L 8 -i 0 -l t64x1 -b 4096 -m 1

can you share batch file for 290h/s to try?

I know, I am the owner Cheesy

The current (wrong) multiplier for yac was 0.001, which would put 280x at 730hash/s. I distinctly remember someone giving me those number when yac went nf16. Well hard lesson for the next time to always confirm by yourself.

Haha yer i was wondering if i missed something and could push my crads higher, but props on that setting for the 750ti Wink
