Well, the battle is joined. I just finished installing all the USB to PCI-E connectors, and am in the process of trying to get it to boot. So far, it's winning. It has an unusual boot-up routine, and it gets to the point where it scans the PCI bus, and gives me (what I take to be) an error beep code string, which reading thru the manual I can't seem to find. Because they decided that having (at least) a directly wired keyboard is _so_ 1990's, the peripherals are USB, meaning both the mouse and keyboard, which aren't active till somewhere in the middle stages of the boot process. Which makes it interesting trying to get into the BIOS screen if your keyboard isn't yet seen by the system. I think this thing and I are going be be doing some wrasseling for the next couple days, looking like it's not going to give up its secrets easily, but hey, I like a challenge! Now to pull all the USBs from the PCI-E slots again, and try to get it to boot up, it didn't like it last time I had all the slots empty, but these things can be _so_ temperamental...

Yep, running currently 7 PCI-E 1.0 to USB 3.0 extenders, have 7 cards in the system, and getting PCI-E resource issue error messages during the initial bootup, but have been moving the 7 cards around in the 11 slots on the board, and think I found the right combo to allow it to boot, though it is still giving me the error squawks, at least it let me install Windows, so that's a start. Just getting ready to install the Supermicro stuff in a few minutes, so we'll see how it goes.

If you have a wired PS/2 keyboard in the closet and port for it on the motherboard, try that to get into the motherboard BIOS. Then look for Legacy USB device settings and set that for Enabled or Auto. Then look for UEFI handoff to USB devices to see if you can get the keyboard and mouse recognized upon first part of the POST process. Might be able to get the USB to PCIe connectors to get polled in the POST process.

Thanks for the thoughts, it seems after doing the slot shuffle, I can now get into the BIOS, set everything to Legacy, running at 2.5 gbs I believe it said, lowest setting it had. I am now at the point where I can install a driver for all the cards, is there a consensus on the best driver version for the 750Ti? I plan on running SoG as well as CPU tasks, was going to assign 1 core per GPU to start with and see if it needed more.

Will talk to Supermicro in the morning about these PCI resource issues, would like to get that resolved, as it boots into the BIOS screen every time, I just say don't save and it continues to boot up, but it's a pain and more importantly, it's not right.

There are worse situations of keyboard/mouse settings, mine with present motherboard and win 10 is that BIOS recognises USB k/bd & mouse and I can do anything I want there, but then I have to use PS/2 k/bd & mouse to install win 10 up until I can install the motherboard drivers.

I have to agree with your assessment of how Win 10 recognizes hardware and gets in the way with what was very simple and easy with Win 7. I had a bad time simply changing out video cards in the Win 10 machine simply by swapping out 670's for 970's using the same video driver. Would have been no issue at all with Win 7. I actually had to pull the 970's and go back to a single 670 just to get Win 10 to revert to stock video driver. Only then could I install the 970's and then put in the proper Nvidia driver that supports OpenCL. What a pain!

What a pain!

Wow, I had no idea it was that bad. Well, I know I will still be running 7 after the end date, but I can't run it forever, maybe Win 11 or 13 will be out, I will be skipping the next even # release, as they are pretty consistent about mucking those up. Any thoughts on the best Vid driver version for running the 750Ti perchance? :-)

I'm running 358.91 successfully on my single 750ti, but not with SoG, just standard Lunatics.
Happy Crunching,

I'm on WIn10 and running 368.81 because I needed it for the GTX 1070.
The only (extremely random) issue is DX12 related, so wouldn't occur on Win7.

I'm running 353.30 WHQL Driver in Win 7 on Prometheus with the EVGA GTX-750TI SC, and the same Driver in Win XP Pro x64 on Exeter with the EVGA GTX-760.

The last I read; however, from other Threads, the consensus was that actually 337.88 was better... However; I don't know if SoG Units will run on 337.88.

I haven't had issues with 353.30, and am reluctant to Upgrade the Driver; as both card models are running well on both systems. BUT, as an aside, I haven't run Prometheus, (Win 7), since getting Andromeda, (MAC OS), running on same said hardware. Andromeda, (because of MAC OS), uses the Alternate NVIDIA Driver 346.03.06f01 which is the ONLY Driver available from NVIDIA for El Capitan ver. 10.11.4. As you Upgrade each OS Version for MAC, the Alternate NVIDIA Driver MUST be Upgraded as well. TBar can tell you what the current version is for 10.11.5 and 10.11.6.

If you stay with Windows, I'd recommend 353.30 for your needs.

As always, good luck. :-)

From what I recall hearing, older can certainly be better, I think I will let a few others pop in with more thoughts on it, and go with the best of the consensus. Thanks guys, I'll check in the morning and see what else there is to see!

I'm running 368 on my 650 on the Intel with no issues but can't remember if it's slower or not I don't think so .

I'm also running 378 on my AMD and it has a 680 and a 970 with no problems and it's flying though units in double time

I'm also running with Lunatic 0.45beta with the sog app if any of that helps

Edit: also I'm running win 7 on both machines

Just a little trick when you do the pci-e shuffle all ways clear CMOS as some times the IRQ's can get all messed up and cause problems.

waiting for end of WoW to try:
GeForce Game Ready Driver - WHQL Version: 372.54 - Release Date: Mon Aug 15, 2016

@all: Does anyone know if the WHQL versions are any safer in general for Boinc or S@h tasks?

Btw Al, I'm not pleased that you're starting a new saga when mine's not finished! :-p
But I like yours much better than mine! lol :-D

Game Ready Drivers have very little use for scientific work, they are keyed more to running the newest games about to be released.

Usually they contain errors that end up getting fixed with hot updates later after they find the problems.

Probably better to wait until they fix out all the bugs

And the trouble is that *every* driver is now labelled WHQL on first release, ready or not.

It's ceased to have any meaning, since they stopped the public Beta programme a couple of years ago.

Thanks for the input guys. So at this point, there isn't a known downside to going with the latest version drivers for the 750? Older isn't necessarily faster? I plan on loading them up this morning sometime, and see how it goes, then load up BOINC w/SoG, and then will be back for questions about command lines, as I hear that they can make a significant difference.
