Message 1808998 - Posted: 14 Aug 2016, 2:29:08 UTC - in response to Message 1808976.  

Richard, thanks for the reply, question though. If the card(s) are happily crunching away on 4 tasks at a time, and then an AP pops up, will it then throttle the card back to just that one task any time an AP occurs? Is this normal behavior, and if so, is there a way to configure it so it will run the AP task as just one of 4, and not be so greedy and suck up the whole card? :-) I presume it is a setting in one of the config files? Thanks!

If you are using an app_config.xml, under the astropulse section find

<gpu_usage>1</gpu_usage>

and change it to

<gpu_usage>0.25</gpu_usage>

With respect to SIV64, you can always click on [OK] > [Latest Releases] to read the changes in each beta iteration to see whether anything pops up that is relevant to your hardware or OS and whether you need to update. He is always adding features.

For example, I use SIV64 to control my Corsair AIO cooler. SIV64 provides much better control and with far less issues than the bad Corsair software. Ray pretty much holds the feet of the Corsair developers to the fire to fix all their programming flaws. When they won't fix the problem, he does.

I also use SIV64 to control the fans on my Nvidia graphics cards. I use the 6 point fan control curves to keep my GPU temps under control. I've never felt the need to use the other popular fan control software, SIV64 does what I need with very little overhead. I just keep the main window always open on the desktop.

You have to explore all the capabilities of the program. Don't be afraid to just explore every menu option and definitely use the ToolTips that pop up when you hover the mouse cursor over every element in every screen to see what it displays.

Excellent! I noticed that I had the yellow ! next to the H115i in the device manager, so went looking for the driver, and came across the H115i forum on Corsairs website. Apparently they start a new issues thread every time they release a new version, and as I was reading thru the last 2-3 versions, I came across much of the same sentiment that you have: Their software is pretty much crap. So, I'll just skip their junky software, and live with the yellow !, it doesn't effect anything anyways. Thanks for the heads up on that, I'll install it while I am working on the new dual 1060 system I am putting together, that has the H115i on it.

All you need to do is install the driver software which is in the Corsair Link software. All SIV needs is the driver to interface to the hardware. You got unlucky with the H115i cooler as it is Asetek hardware under the covers. I have the H-100iV2 cooler which is Asetek also. It is much better to have CoolIt AIO hardware as it is more competent. You will have to install the CL link software which loads the drivers for the cooler. You can then uninstall the CL software as it leaves the hardware drivers behind I believe. That should get rid of your yellow ! in Device Manager and allow SIV to control the hardware.

The drivers you should be looking for I believe are the Silicon Laboratories Corsair Hydro Series 7289 USB Device under USB Universal Serial Bus controllers in Device Manager.

The files should be SiLib.sys and SiUSBXp.sys and should be in:

C:\Windows\System32\Drivers\

The document for explaining the SIV control of AIO hardware is:

Using SIV to control Corsair Link hardware]

If you read through the threads in the Corsair Cooling forum, you will see Ray everywhere. He is the goto guy for AIO hardware and software knowledge.

Keith, thanks for the heads up, now I just need to download it. Looking again at the forum to see if there's any new news, I take it that Red-Ray is the Man around there. After reading it a bit more, I have to agree with what some posters are saying, why don't they just hire him to debug some of their faulty code? He apparently has the ability to do so, but it seems from how things are('t) progressing, that they either currently don't have the skillset/ability to fix it, or they don't care. Neither of which are encouraging. Well, I'll just use SIV to control the cooler, that works for me. You mentioned Asetek vs. CoolIt, so it appears that Corsair is just rebranding other mfgs products with their names. CoolIt I take it is a better quality mfg than Asetek?

I suppose one could just go out an purchase them from the OEM, if they sell under their own name, but which versions of Corsairs products are the CoolIt style? I thought the H115i was the bad boy of their lineup, too bad they went with what appears to be the inferior brand for their flagship product. Wonder why, cost? Thanks again for the tip about SIC controlling the cooler, that's a good thing to know!

@Al
for better using and controlling your machine use a cc_config as shown:

<cc_config>
<options>
<start_delay>120</start_delay>
<ncpus>48</ncpus>
<use_all_gpus>1</use_all_gpus>
<skip_cpu_benchmarks>1</skip_cpu_benchmarks>
</options>
</cc_config>

This way you can free some CPUs if needed for other work easily by setting ncpus to a new value.
I excluded the cpu Benchmark also.
The start delay is necessary to give Boinc enough time to find and setup all your GPU's

heinz, thanks for the sample cc_config, I'll make note of it when I get back upstairs to work on it later tonite. :-)


Keith, just spent 30 seconds Googling CoolIt, and found that they only OEM thru Corsair. But, it appears that they also make a higher end unit, the Hydro Series™ H110i GT Extreme Performance Liquid CPU Cooler. I guess I'll have to admit, I was swayed by the number, and failed to do proper due dilligence. Next time I'll know better, and the price is basically the same. Lesson learned, and hopefully I'll not have any issues with it even though it isn't a CoolIt built unit.

Yes, Red-Ray is the man. From reading the forums .... and official Corsair representative comments ..... I gather there is a bit of "not invented here" syndrome going on. Red-Ray has shown them their flaws and offered solutions, but they just ignore the suggestions. There's a list of ongoing flaws going back 3 years or so that are still in the faulty Corsair code in the forum.

Yes, Corsair just rebrands the AIO hardware. Asetek got into a patent pissing contest with every other maker of hardware and intimidated them into dropping out of the market or making major changes to the hardware to not make a patent infraction. CoolIt does mention their hardware on their website, then simply points you at Corsair for purchasing their product. The H-110(i) (GTX) etc. is CoolIt hardware. Ray explained that the superiority is in the electronic hardware and firmware controlling the cooler, not necessarily in the physical parts like the radiator, cold plate, pump and tubing. He can hook into a lot more of the control functions with the H-110GTX and the other CoolIt sourced product. For example, he can't control LED lighting in Asetek products, but can in CoolIt products.

If you look at [Status] > [Link Limits] in SIV64 you will find the matrix of Link devices. Look at the color blobs for all the AIO H coolers and match them up to the legend at the bottom of the panel. If you see a hot pink blob next to the device, that means Full Control of the device. That also matches up with CoolIt hardware.

Message 1809094 - Posted: 14 Aug 2016, 16:17:36 UTC - in response to Message 1809090.  

There have been some early "teething" problems with the hardware from either source when new models have been released. That is sort of expected. After the products are mature, there have been very little issues in the longer view with both sourced brands. Normal "infant mortality" issues and some very few long term, many years in use failures, but really a very low percentage of total product. The mature AIO is a pretty much set and forget product.

I'm also referring to the radiator, pump, cold-plate and tubing hardware. Fans are another total thing. My stock Corsair SP-120L fans didn't last a month before their cheap sleeve bearings started rattling so loud it jostled the teeth out of my head. And spraying bearing oil out of them around the case. I replaced them last weekend with good Noctua NF-F12 PWM IPPC67 2000 rpm fans. Overkill for my use actually. I should have just bought the normal NF-F12A fans at half the cost. I've used them on my other two AIO coolers for over two years now with no issues. They provided better cooling at MUCH lesser fan noise. And with their bearing design they will last a lifetime.

Message 1809096 - Posted: 14 Aug 2016, 16:44:55 UTC - in response to Message 1809094.  

Did a quick search on the fans you mentioned, you said that you bought NF-F12 PWM IPPC67 ones, but when I Googled it, it suggested the Noctua SSO2 Bearing, Retail Cooling NF-F12 iPPC 2000 IP67 PWM instead. Is this the one you meant to say, as there was only one result found which lead to a review of the 3000 rpm variant, where it says

Have you read the review of the NF-F12 IPPC-2000 PWM fan? If not, you really should. This fan continues onwards from where it stopped, and kicks it up a further two notches. So much so that you now have a NF-F12 with max RPM of 1500, 2000 and 3000. But unlike the 2000 RPM variant which comes in PWM, 3-pin and IPPC67 versions, you only get one version of this fan. At this speed, I dare say one is all you need. Thanks to Hank from Performance PCs, we now have the chance to take a look at the fan in detail.

Or, is it all the same thing and they just misspoke? You're correct, not inexpensive fans, but should last a very very long time.

Hi Al, no I got the naming wrong. You have it right. There are 2000 RPM and 3000 RPM variants of the Industrial spec Noctua NF-F12 fans. The IP67 certs are for dust and moisture intrusion. Definitely lifetime quality. What I found is that 2000 RPM was overkill in my usage. The normal NF-F12 1500 RPM variety is more than adequate. When I put the new fans in under my old speed control curve, they were running near the top of their rpm range and my radiator internal water temps were higher than before. Once I reduced the maximum rpm range down to 65% or 1200 rpm, then my temps fell back to the point where my temporary Noctua NF-S12 fans had the radiator. The iPPC fans push an ENORMOUS amount of air at incredible static pressure. I was defeating the heat exchange capabilities of the fin structure in my H-100iV2 30mm thick radiator. The iPPC fans would be a better fit to thicker radiators like my H-105 38mm thick radiators in my other crunchers. You can spend the extra $8 for the iPPC fans and get the benefit of lifetime fans at a very reduced noise footprint or just go with the normal 1500 rpm NF-F12 fans and run them closer to their normal 1500rpm spec. I am at 52° C. on my H-105 radiators fully loaded with SETI CPU and GPU tasks. The NF-F12 fans normally run somewhere between 900-1500 depending on workload and how hot the room is. A/C set at 78° F.

Al, I hope I haven't come off as some fanatic about Noctua fans. I just have very good luck with them and haven't seen the need to try anything else. Most of the negative comments about Noctua fans is the color scheme is offensive to many builders and they won't use them. I believe in "form follows function".

If you can find some old Gentle Typhoons, everyone always raved about them. I have also read very good things about the EK Vardar fans for use with radiators. Both of those not necessarily cheap either. You get quality for what you pay for in the marketplace. Google is your friend.

Oh heck no! I think they are the cats meow too, I have them (as well as their CPU coolers) on one of my dual Xeon rigs, it's an EVGA SR-2 running X5690's @ 3.47GHz, and the temps are averaging a very reasonable 50c, so no complaints there. I really don't mind spending a little more money on something that is such higher quality, because it's one less thing to go wrong, and it certainly won't be the weakest link in the system. It's not like it's a multi $100 difference, so I go with them whenever I buy fans. Sometimes there are higher rated fans in terms of airflow or maybe even noise, but when you add up all the things that they do well, overall they come out on top for me. I think I own about 25 of them between my Intel motherboard systems and my Xeon ones. The only systems I am not using them on are the Supermicro based ones, I am using their OEM cooling solution, and it works very well. I would certainly hope that they use high quality parts for their coolers, because these things are going into servers, and that is the last place you'd want to skimp.
