Yeah, and Nah, I only have five rigs running F@H. Two Thuban 1045T rigs, #1 with 2x 270X 2GB cards, #2 with 3x GTX950 2GB OC cards, two G4400 OC rigs, #3 with 2x 7950 3GB cards, now running at -20% powertune, due to heat reasons, #4 just put back into commission, with a single GTX750ti, and rig #5, my new main rig, with an i5-6400 @ 4.455Ghz, and an RX 460 4GB Nitro card, and a 40" 4K monitor.
Is anyone else using a GTX 750 (non Ti) by chance? I had one laying around and its only pulling 300 points a day. That seems really low compared to my GTX 950. Im wondering if its driver related? Its an early revision card, it says GM107 on die. Its also paired with someone elses Christmas present 6700K, but its not Christmas yet is it.
Thanks for the warm welcome guys! I've been running my 980ti since it was released, and I've suddenly decided its time to order a 1080, hopefully I can get one here Monday. Now I just need to make sure my power supply can feed both cards.
Nothing like a little competition to empty my wallet.
Im up to:
5820K
6800K
6700K
6100T
2x GTX 980
2x GTX 950
1x GTX 750
You've got to be one of the top 10 computer nerds on AT.
I mean that with sincere respect.
Larry, not sure why all the issues. When running dual cards (I have 4 dual card boxes ATM), I run everything stock, and run the card fans at 90%, the box side cover off, and one extra 120mm fan pointed between the 2 cards. Oh, and at least one slot open between cards. No problems @!My GTX950 2GB OC (MSI) cards seem to be downclocking slightly too. When I first installed them, they were clocking around 1290 core, now they're at 11xx core, and holding steady at 80-81C, which is, I'm guessing, their thermal limit.
I'm running into BIG issues with my G4400 OCed rig, with the TWO 7950 3GB cards. These things are power-hungry monsters. I downclocked them to 700Mhz core, and powertune limit -20%, and they're still cooking my rig, at up to 87C. (Better than 91C, let me tell you that.)
Anyways, downloads were going slowly, and I went to burn a DVD, and UH-OH, no drive. It had disappeared. Well, the top video card, is right over the M.2 slot and the southbridge heatsink is right between the two video cards.
I rebooted into BIOS a few times, and it wouldn't even show my drive.
I replaced the SATA cable, and that seems to have fixed it? Not sure if it was just because I let the rig cool down, or what. It didn't want to boot into Windows several times, though.
This dual video card thing is really kicking my ass. Now I remember why I avoided it so, after having similar types of issues with SLI GTX460 1GB OC cards.
Edit: And if you want to run dual cards, don't pick just any old video card, you need to really research which cards are capable of running dual, without overheating.
These HIS 7950 3GB cards were bottom-of-the-barrel as far as cooling goes, I think that they have a single fan in the middle of the card.
The 1080 takes less than the 980TI. only about 200 watts or less. I run 2 980TI cards and it draws less than 600 watts. So any quality 750 or more will do the job,.
But 850 or more would be safer.....

I had to check, because it has been a while since I upgraded this PC, but I've got a high quality 850 in there. Just go happens my local Best Buy had the 1080 Founders Edition in stock, so I picked one up a few hours ago and the system appears to be happily chugging away with both cards now. I lowered my CPU threads from 6 to 4 (i7-6700k) to give little more headroom to feeding both cards, looked to be using between 30-40% with it paused. I'm not sure if that was necessary, but I didn't want to choke either of the video cards.
refresh our memory, what cards ? The only thing I use is EVGA Xprecision and it overclocks and regulates everything automatically. My gut tells me whatever software you are using is slightly downclocking to keep things cool or within tolerance, and its nothing to worry about.
At least in my case, my cards have been running 100% for months with no break, and apparently no damage.
Yes, feel free to play with cpu allocation, just check utilization after and always use even numbered cores, 2,4,6, etc. If everything is running, and you have 95% or less utilization, you are good. But since the cpu only gets 20k or so, no way you want to limits the GPU ever, since yours do 600k or better each.
I turned off my 6700k altogether for CPU, since it was getting 10k. Not worth the risk for me.
IIRC, by default the 2nd bios is just a back up bios incase flashing of the 1st 1 goes bad.Oh yeah, I discovered my 7950 3GB cards have an A/B BIOS selection switch. At least, it's some sort of switch. And although they are identical model cards, for some reasons, one of the cards was set to one setting, and the other card was set to the other.
Any idea what they do? Overclocking BIOS? Could it be juicing the core with more voltage, and that's why I've got temp problems?
Well I am still only CPU only, since well my mobo won't be arriving until the 12th of dec at the very latest , stupid Australia post, stupid USPS. I have just ordered another pair of E5606's since well the seller isn't responding, and has since refunded me. Grrr
On top of that I don't have a DVI compatible monitor to check if the card works or not, so a DVI to VGA adapter is also on its way
uhm guys i may have stumbled in a bit of a problem but i'm not really sure. i was checking everything as usual and i noticed a drop of almost 40k in my PPD; a quick look with rivatuner and my 24/7 card dropped around 50 Mhz from her boost frequency. the voltage dropped accordingly to a couple bins less than usual (it's still under the card's control, i'm not forcing a fixed voltage). now, while she's running at excellent temps, steady at 61° celsius, well below any thermal limits, i decided to give her some rest and after a couple hours idle she was back again at top frequency and voltage, always at 61°. now, after only 4 hours, she's dropping again albeit not as much as before. please tell me i'm not frying the board's VRMs... if indeed i'm putting too much strain on the power delivery circuits, i'll have to alternate the cards to give them rest instead of running both of them... and i don't think it's a power supply issue, there is no drop or throttle whatsoever if i run them both while gaming, even for hours, nor the PSU's fan does spin up to maximum speed. did you guys ever experienced something similar? i'd like not to fry one of my cards if possible...
