Changing the GPU to +150 I have an 3KHs increase in my average rate.
Both CPU and GPU temperatures increased 1ºC.

With an open window, and continous air flow, both temperatures decrease 2~3ºC.

Now I need to measure the power consumption. Need a Kill-A-Watt ASAP.
Problem is that no one sell it here and Brazil and shipping fees are high.
Will try to find a way.

I'm also tempted to go Windows because Cudaminer and Linux are a pain to set up. Wasted a day finding out that my Xubuntu 12.04 distro cannot compile Cudaminer because of clashes with old versions of libcurl. So I'm just gonna install the minimal Ubuntu 13.10 and work with that.

I'd reccomend waiting for BAMT 2.1 which will feature nvidia support out of the box wink.gif

64bit os too.

I'd use Windows for now...and as for the hdd problem, I've had tons of problems with CSM on many z87 boards, I hate that stupid thing lol
Never had a problem on older platforms.

I can't wait for NVIDIA support in BAMT, it'll give me a good reason to switch both my rigs over to BAMT from Win7. :thumb:

The best part, they pull 120W from the wall total.

Parameters at T5x24 and that's basically it.

It may be because the VRAM used is Hynix BFR

H5GC2H24BFR-T2C modules are rated to run at 1250MHz using 1.35v and 1500MHz using 1.5v
(see http://www.overclock.net/t/1468166/gtx-750-ti-mining/100#post_21878424)

what's likely the issue is they are set to run at 1.35V by default = 5 Ghz

A big factor is the efficiency rating of your power supply as in how many watts at the wall does it take to make a watt the card pulls. In other words its taking 70 watts at the wall to supply the card with 45 to 50 watts which is what the un modded bios is stuck at. By adding 1 card at a time I confirmed it was exactly 70watts per card at full load at the wall at least on my el junko 500 watt 40 dollar powesupply. I am replacing that with a high end 1000 watt this weekend and will unlock the bios on all cards and add a 6th card and let you know the new stats. The short answer though is bone stock no overclock your looking at 250khs at ~70 watts at the wall

Update, took out the junk 500 watt power supply and put in a corsair rm 1000, slapped in the 6th asus gtx 750 ti on the gigabyte 990fxa ud3 cable 1x risers. 1500 to khs no mods or overclocks. Card temps 58 to 62 Celsius 445 watts at the wall. Will attempt overclocking and bios mod again this. Weekend after I confirm it runs rock steady till Saturday.

Try some other algorithms like say ultracoin which is scrypt-chacha...and more profitable than scrypt anyway. thumb.gif

Just to inform that this last tweak is not stable.
Usually after one hour cudaminer stops working.

Very nice rig.

Are you using x1-x1 or x1-x16 risers?

I bit the bullet and ran Windows for my miner. I have two EVGA SC cards set up and running. Still need to install the PNY cards for tomorrow. Here are my OC settings after going for my 300 Kh/s per card goal, using -l T5x24 -i 0 -C 2 -m 1



GPU 0 is running a bit toasty at under 80 degrees C, as there are no risers to separate the cards and the fan is directly behind the other GPU. GPU 1 is at 50-53 C. I de-synched the cards so that GPU 0 can run a bit slower and with less voltage, and let the other card pick up the slack.

[Edit] I pushed the GPU and memory speed of card 1 up to +100 and +600 respectively and now am getting close to 620Kh/s between two cards.
