Thanks everyone for the great insight. Looks like I need to go with the GTX 750 Ti and spend $150CDN to get a worthwhile performance boost. Some thinking to do.


Not sure how the us dollar conversion goes, but here is an EVGA GTX 750Ti "B-Stock" for $89.99.

I stumbled across this guy on YT, who is building weird but wonderful stuff. Like a CPU heat sink on his GPU, and thereby cooling his GPU under full load at 20 degrees centigrade less, against a way lower sound level.

And then that GPU built into his self made PC case, with the motherboard turned sideways so the ports are at the top of the case, and two huge 140mm fans in the bottom taking care of all the cooling.

Maybe it gives ideas. ;-)


Reminds me of the SilverStone Raven RV02 and Fortress FT02:

I'm running a four 970 machine over at Einstein and its rock solid(using 353.62drivers). They are the Nvidia reference models you buy at BestBuy. There was a sale on them for $329. Installed 980ti hybrid kits and running memory P2@3500mhz, and boost clocks around 1400. Temps for the cards average 38-41C, on full 99% usage.

I also own four 980s, found some new ones for under $400 so at that price they become a good buy. If your a fan, keep any eye out for deals on EVGA's B-stock page, they had 970s for under $250 awhile ago.

I built a similar rig using a CaseLabs Mercury Case, its amazing. Tons of room for the hybrid coolers, great support for the gpus, and its made from thick aluminum. If your going to spend 300+ for a case, check it out.

Built a new rig using a 5930K, four 970 hybrids, in a Caselabs Mercury S8. Currently it is crunching at Einstein@Home, but will make a visit here soon.

Congrats everyone on their achievements!


I just recently broke 100 million. WooHoo! :-)


Nice! hope to reach that goal some day myself.

You ought to see how much room there is, in a Corsair Graphite 780T! I've just bought one for my new build....it is massive inside and out. I could've gone for a Skylake build, but have stuck to the promise I made to myself, nearly 20 years ago, to never be at the 'bleeding edge' again. The money saved, meant I could buy better quality/better performing components.

Full details are; Corsair 780T (white), Corsair AX860i PSU, Gigabyte Z97 G1 Sniper, i5 4690K, Gigabyte R9 390X (8GB) 32G Crucial Ballistix 1866 MHz RAM (timed 9-9-9-27), 2 X WD Black 2TB drives, Samsung 850 Pro 256GB SSD (solely for OS etc.), LG 16X Blu-ray drive, topped-off with an Asus Xonar D2X sound card. Just waiting for my Win 7 Pro DVD.....


Nice, take some pictures of that rig when your done. Looks like a solid build.

Here is My first quad GPU host, my daily driver.



Case: Fractal Design Define R4 Black Pearl
PSU: Corsair RM650
MB: Asus A88X-PLUS
CPU: AMD A10-7850K
CPU Cooler: Cooler Master Hyper 212 EVO
Memory: Kingston HyperX FURY Black 8 GB
SSD: Kingston HyperX FURY 120 GB
HDD: Verbatim 2 TB SATA 6 Gb/s 7200 RPM 64MB
Optical drive: Samsung SH-224DB 8X DVD+/-RW SATA
GPU: 3 * Asus GTX750TI-OC-2GD5 (two in PCI-E, one in PCI-E extension card), 1 * AMD Radeon R7 Spectre (integrated in CPU)

As You can see, it draws about 230-240W (230V) when running 4 AP GPU units and two MB CPU units.

Curren RAC is not what it should be, 24h off-line last weekend when I was away, and 3rd 750Ti just installed. Could be around 40K, wait and see.

(and Yes, there is dust inside case, cleaned it after photo :)


Cool riser setup! I love the fractal cases.

133.3 12v rail....sweetness. Your MB looks dink in that big ol' cube case. I could see Zalster's rigs with the multiple rads fitting more comfortably in one. Looking good, really good.

-Edit, Holy crap -- just noticed those kick ass case fans. Are those AC powered Deltas?

Well Zombu2 just ordered 8-980tis, so yeah, hammer down.

Today was a fun day of moving graphics cards from machine to machine. The machine below is Sanford. I put the Titan X in there along with a 980, and a 960 shorty. The case is an Enthoo Pro Metallic Green.



Seti Jr. gets an upgrade. It received a 970 from Punisher to go along with a Titan Black...far cry from the two 750Tis.

Just got a new gpu to add to the collection. The card will be replacing a 980, and will get a hybrid kit like Zalster's in the future.

Do you realize what kind of performance you could have with four GTX-750 TI SC cards crunching 2 Units at a time on each card???!!!???


I don't.

Please enlighten me.

Roughly, a RAC of 11,000 per card (MB only).

And to confirm that, here's a GTX 750 Ti I started from scratch on a new account on 31st. August - around midday, so just over 27 days before it cracked 11,000 RAC, and still rising.

It's running as described here - MB only, two tasks at a time, SETI not crunched on the host CPU. The notch is where we lost some crunch time, because of the fire in the co-lo.


Here's a rig I'm running, 2-MBs at a time on a 750Ti only. G3258 with no tasks feeds the card, and is a 24/7 seti cruncher.

Zalster,

Are those radiators nice and toasty? Nice rigs, so jealous. Hey I just added another 960 to my GPU army ;) Hurry back so you can push my rigs off the top 20 page.

You may want to stick with AMD, and there are some AMD pro users around the forums that can help you out.

If you have two machines maybe move your AMD cards to one machine then do a Nvidia build. Nvidia dominates MBs, and AMD dominates APs. Though that may change with new programs in the future.

The Nvidia card/s I would get would be a 970 and above. I run some 960s and 750tis and they are great low cost cards, but for speed and efficiency the 970/980s do an awesome job.

I'm leaning towards faulty power switch/lead. My corsair case had a faulty lead to its power led. I had to take it out and resolder the connection at the led. If you have a voltmeter you can do a continuity check on the power switch or test the motherboard with a different power switch.

My Deepcool system. I bought these items cheap and re-purposed them. The case was $40, the PSU was $20, the MB was $20, Ram $20, HDD from a busted external USB drive, reused old heatsink from a previous build, the GPU from ebay for $99 and the G3258 CPU was $60. The machine produces around 11-12K aday using the gpu only. It acts crazy when I take a core away, so it gets feed by the whole cpu.

I have a similar case, the steam castle by deepcool. Ugly as hell but functional, picked it up cheap when it was on shellshocker. I'll take some pics of it when I get home from work tomorrow. I'm running a single 750 in there with a dual core on a cheapo mb, but it works like a champ, though I have to dedicate the entire cpu to the graphics card. If I use just one core it throws a fit.

Not getting AP tasks (when they are available) is down to your SMALL cache size - an AP takes about 0.5 days to run, while an MB takes about 0.1 days, so if your cahce is set to 0.5 days, plus 0 you will only ever get APs when you almost right out of MB tasks, indeed, you may not get any then.

With a small "store at least" setting you will have a small cache, probably well below the 100 that is allowed for the CPU, set it higher and you will find that you don't have to tune it so often.
A zero "extra days" will not always work, setting it just above zero will ensure that you will make regular requests for work, not at the default interval that is set server side, again this will ensure you request a replacement task every time you return one.

My cache setting is 6 days, plus 0.01, and all four of my rigs have full caches (well, bouncing off the limits) most of the time and I don't have to worry about spending time increasing and decreasing the settings. (One of mine has a pile of ghosts that will vanish one day...)


Good information right there.
