Forgot to ask this question. The 8gig Ram mod that I have in my motherboard is rated for 1600. The Giga board will only let it run at 1333. Will I see much of a diff running at 1600 in my new motherboard?

Not much for most DC apps. The Gigabyte board I'm running has a special BIOS setting to bump the memory speed to 1600 if the ram is capable. Earlier today I pulled the X4 610e on that MB and put in the new 95w FX-8310. Running at 10% OC (3740 MHz) and with 7 CPU tasks and 2 GPUGRID tasks it's at 270 watts (2 x 750 TI GPUs) for the system. It does bounce up to 4100MHz every few seconds so the turbo core feature is kicking in. Very quiet at 47C CPU, 52C & 55C GPU temps. Inexpensive Antec 300 case with some extra fans (side and front inflowing) and all fans at lowest speeds. Used a Zalman enps10x CPU HS/fan I had laying around. Probably uses more power than an i7 setup but not bad for 9 WUs running, and very quiet. The GPU efficiency jumped 5% (into the mid 90s) on both GPUs so they should be running faster (the low wattage X4 610e must not have been giving them the best support). Pretty happy with it so far.

if you are CPU bound, and 750s you have got 2Gb, you can try running 2 WUs at once - this will mask out the CPU. that's the only way for me to get above 90% on a 970.

Thanks for the suggestion but as mentioned above, they're in the mid 90s with the FX-8310. On the X4 910e the WUs were running at 89-90% and about 30 minutes slower. Trying to run 2 WUs on a 750 or 750Ti would miss the 24 hour bonus deadline as the current long WUs are running at 12 hours - 13.5 hours on my 750Ti GPUs depending on the WU type. There's a reason for the deadline. The project wants a fast turnaround.

Thanks for the reply. I got the system rebuilt and am in the tweaking phase. Basically I was dead on with my power calcs. I can run 6 WCG WUs and 2 GPUGrid with 315 watts at 4GHZ. The stock fan is running at 2800 RPM so I need to get the Artic Freezer out and replace the stock unit. Looks like I will get WCG done in 2.5 hours instead of 4.5 to 5 on the FX8320. Plus I have a new GTX 750 running at 1225Ghz cranking away. The 750 is a wonder at 55watts. Real nice card. Dead quiet too.

I may be able to reduce the wattage down another 10-15 watts. This Asus Gryphon Z87 is an amazing server based board with a ton of settings and temp sensors. Very happy with it.

Which WCG CPU subproject WUs are you running?

Mapping Cancer and Genome. I do AIDS on my Androids.

I saw a GTX 760 Dual (2304 cores) with 2GB for $220 on Newegg yesterday. It is gone today. I was really close to getting one. I didn't cause of power concerns. I couldn't find how much it takes. I estimated it will use 300 watts. Even at 250 watts I thought it would be best to save for the 970.

I was very tempted.

Wonder if and when the GTX 960 will come out. I seem to be a x60 guy. First the 560ti then the 660ti.

I upgraded to 16gig of 2133 XMP memory but it is crashing the display driver and blue screening the PC. If I suspend just GPU activity it runs fine. If I turn it down to 1600, it runs fine.

What is the issue here? I wanted faster memory for WCG but it is killing GpuGrid.

Any ideas or help would be appreciated.

I didn't follow the thread, but a few points regarding memory stability:

- higher clocked memory sometimes requires higher voltages. These much be set in the BIOS according to product spec

- do you have 4x4 modules? If so, the command rate should be set to 2T. Most XMP profiles include it just like this even for 2 modules, but if not this may cause your troubles

- if the mainboard is relatively new there might be problems in thie BIOS which might already be fixed with an update

- when you set it to 2133 MHz you also set XMP timings, don't you?

Scanning for our furry friends since Jan 2002

It is 2 modules and XMP sets all of the settings including the 1.65v. My BIOS is also up to date. Not sure about this one. Need to do more research.

I fixed it. Silly me for trusting the Asus update GUI. I clicked on check for BIOS update and it says I am current (1/14 dated BIOS). Go to the ASUS website and there are 3 more since Jan 2014. Some update GUI's are worthless. I downloaded the latest one from Sept 2014 that referenced system stability fixes and so far it is running great.

Does anyone know if increasing the RAM speed by 600Mhz while still maintaining a CAS of 9 and 1T will speed up GPUGrid?

Thanks for any replies. Working my way to 100Million credits.

I don't think so. What is the RAM speed now?
Could you please tell me the clocks, multipliers and voltages of your CPU ? (reported by the CPU-Z utility)
For reference: my i7-4790k runs at 4487.68MHz (99.73*45) 1.3V core voltage, NB (Uncore) frequency 3990.5MHz (40x)
RAM: Kingston KHX1866C10D3/4G, 931MHz (1862MHz DDR3), 10-11-10-30-243-1T, 1.5V,

CPU is 40x100=4GHz. I turned boost off as the cpu fan was running loud.

The RAM is 2133Ghz 9,11,11,28,278, 2T all settings came from XMP

Interestingly I downloaded EVGA Precision and overclocked the GTX 750 from 1225Mhz to 1300Mhz and the memory from 5000Mhz to 6000Mhz. I need more time to see how much faster WU will get done but the card only went up 3 degs and seems quite stable. This is a great little card for $80. Glad I bought it.
