post #16261 of 18191
noiudea under bboinc but in my rendering with GPU im getting increase of perfromance
post #16262 of 18191
few pourcents ?
post #16263 of 18191
not sure of percentage didnt do calculations but also im hitting GPU throttling speed so even being faster it is slowed down by temperature hence the main problem.
in any cas e good enough percentage that it is worth looking into it.
across 8 GPUs even 5 sec faster per frame accumulates over hundreds and thousand frames of rendering

Like it throttles however, it downclocks 200mhz! Temps are in check, no power limit and it acts like this with adaptive and power..
I can't remember any of this weirdness when I first bought my cards and flashed occasionally back in june.. Seems like recent drives also affect the clocks/mV?
That's because you SHOULD NOT ADJUST VOLTAGE ON CYCLOPS 3

- Max voltage on these cards is 1.274v without hard-modding or pencil modding.

- If you install any version of the Ultimate BIOS and are not getting the voltage specified (or slightly above, indicated in software), do the following:

1. Uninstall AB and PX, reboot
2. Use DDU to remove drivers, reboot
3. Re-flash BIOS, reboot
4. Re-install drivers, reboot
5. Re-install AB (I prefer it to PX, but it's up to you)

- The Ultimate BIOS downclocks both core and voltage normally IF installed correctly and NVCP performance setting is left on Adaptive, the default setting. You only get specified vcore under load.

- The Ultimate BIOS won't temp throttle until 85 deg C.

- DO NOT use AB or PX to increase voltage using the Ultimate BIOS; voltage is preset. Use the version with the specified amount of voltage you need. Remember that voltage will only ramp up under load.

I'm going to start re-directing all inquiries via PM to this thread, so that everyone can benefit from the info provided. JPMboy, Charlie and lilchronic can also provide good info about issues like this.

Same for cyclops 3... and the silly # of PMs received. (tho, I'm keeping my TXs tongue.gif )

More likely our existing USB subsystems are not up-to-par.

How do you know if it throttles if the sensors are not working in tcc mode ? Is it possible to monitor with aida64 in tcc mode ?
post #16266 of 18191
nvidia-smi is located usually at: C:\Program Files\NVIDIA Corporation\NVSMI\nvidia-smi.exe

Go there with a command prompt and administrative privileges and type nvidia-smi -s. This gives you the current status and the status of TCC mode after reboot.
Set exclusive compute mode enabled for the first GPU by nvidia-smi -g 0 -c 1
Set exclusive compute mode disabled for the first GPU by nvidia-smi -g 0 -c 0

now ther eare other command flags with nvidia-smi one of them lists oall gpu devices and curent fan rpm and temperautres which I used to monitor/
post #16267 of 18191
You can limit the power to avoid throttling:

-pl --power-limit= Specifies maximum power management limit in watts.

Will try out now ^^

cd C:\Program Files\NVIDIA Corporation\NVSMI

C:\Program Files\NVIDIA Corporation\NVSMI>nvidia-smi -i 0 -dm 1
Set driver model to TCC for GPU 0000:01:00.0.
All done.
Reboot required.


Edit: Boing is trying to reconnect to the client forever when I use the TCC mode.
Reverting back to WDDM.

Also, a 2nd pump as redundancy is not always great in series as some pumps when they break have exceptionally high resistance to flow. If you were dead set on having 2 pumps with those rads you could consider 2 loops.

By example, My D5 Laing pump ran at 40% power setting to achieve optimum flow in a setup using 2 large rads, 2x MB blocks, 2x GPU blocks, CPU, res, filter/flow monitor (these can be very restrictive).


I haven't bothered doing the calculations for flow rate, heat dissipation etc with different setups for over a year.... there are a bunch of good threads on all of this at OCAU though in the extreme cooling forum (overclockers Australia).

Currently running a xspc 750 pump/res combi not sure of the exact model its molex powered so dont think it can be adjusted. 2 loops is the way i wanted to originally go one for the cpu and one for the gpu but im running low on space and not sure where i would fit a 2nd res. i read on overclock.net that the rads im using have a high resistance, according to them my pump has a max pressure of 3.59 PSI and the pressure drop is as follows.

CPU block 0.9 PSI
GPU block 0.9 PSI
HW labs gtx rad 0.7 PSI each

Total pressure required 3.90 PSI

So to me this looks like my pump is not enough can anybody quote on if these figures are accurate ect

April? Damn, that's a lot sooner than I expected. The used Titan X market is going to take a dump, I imagine?

I thought about selling my titans for the mast couple months now, mainly because I went overboard by getting two, and the fact that I don't play as much as I used to because of school and work. I still contemplate selling them, but I know these cards will last a few good years.
