NVIDIA GTX 750Ti / 750 (Maxwell) Owner's club - Page 5

post #41 of 3177
Just installed the EVGA 750Ti SC and man, this thing is tiny! biggrin.gif I didn't tear the card apart but there's an iron choke located somewhat in the same area as in the reference model, so I guess it might be possible that this card's based on the reference design?
Sooo... How's the 750Ti performance-wise? I had quite hard time really "feeling" the difference to my ex-GTX660 in so I'd say pretty darn good. There's no micro stuttering or anything, and everything feels very smooth and consistent, maybe a bit "smoother" than before.
Power consumption? Max. 129 watts during Dayz and 3Dmark 11, which is tens of watts less than before. Nice! Haven't had time to test other titles, though, since I installed a fresh 8.1 yesterday.
Then the cons... Minimum fan speed is locked to 40%. EVGA, why? It's currently running THREE DEGREES CELSIUS above ambient and the fan is clearly audible. And coil whine... headscratch.gifmad.gif I mean, the card is great but I feel like EVGA's letting me down here. I'm seriously considering moving to Zotac.

It's an iron choke, coil whine is no surprise.

Try using Kepler BIOS Tweaker to edit the BIOS to slow down minimum fan speeds

Anyhow as far as memory for GTX 750 Ti:
(Reference = Hynix H5GC4H24MFR-T2C rated for 5GHz)
ASUS Dual fan (3+1 , 6 pin) ... Samsung K4G41325FC-HC03 rated for 6Ghz
Galaxy GC (3+1 , 6 pin) ... unsure how high the Hynix H5GC2H24BFR-T2C will clock on memory though it's rated for 6GHz
Gigabyte Dual fan (2+1 , 6 pin) ... Samsung K4G41325FC-HC03 rated for 6Ghz
ZOTAC dual fan (2+1, 6 pin) ... Hynix H5GC4H24MFR-T2C ... 5Ghz , same as reference memory
EVGA FTW (2+1 , 6 pin)... Samsung K4G41325FC-HC03 rated for 6Ghz , noting that the memory phase is d-pak +iron choke

steezebe please run specviewperf 12 CATIA Benchmark. If it gets 20+ score (Quadro K2000 score) I'd be surprised

frown.gif This is the last time I'm buying a card blindfolded... I heard EVGA released an official bios update for their ACX series to reduce fan noise, so I guess I'll wait a some time to see if they come up with an update for the SC model. If not, I'm going for Zotac.

I have 68xx and 7xxx cards all with chokes like that and they still go today some had up to 1.7v in them so i dont think just becuase the parts are not the best does not mean they cant overclock nicely without issue.

no whine at all from my ftw card
post #45 of 3177
Agreed, and my card boosts very nicely indeed, but there's no way around that the fan profile is ridiculous and it wouldn't cost a fortune to replace that one choke with a little better one.

Just unplug the fan see how it reacts temp wise i mean if it bothers you that much ??? bet its still halfway decent on temps smile.gif

Might just do that and place a Scythe GT below the heatsink, but then again, it'd still sound like I had a small grasshopper trapped in there somewhere lol.

Well, I got my Zotac 750Ti reference a few days ago and finally sat down to toy around with it today. I'm new to this whole GPU OC thing, and still figuring out how far it'll go but so far it seems to be stable at these settings

e6z.png

however when I check my monitoring software it only shows max. core clock of 1311Mhz. Any thoughts why that would be happening? I don't think it's hitting a temperature target, because the card topped out at 50C and it's not hitting the wattage wall because the TDP topped out at 86.9%.

EDIT:

Oh, and if someone's interested here's a picture of it with the shroud off. Memory seems to be, as much as I could see without taking the heatsink off, Samsung K4G41325FC-HC03.

But you have EVGA stepup and Maxwell GM200/GM204/GM206 is supposed to come in second half of the year so you just might squeak by. If not, the resale value is great. wink.gif

Anyhow, there's supposed to be a BIOS update for the EVGA FTW edition that lowers idle fan speed. People complained that the idle on the new BIOs, although a dB quieter, is still too loud.
Quote:
Much like the previously-reviewed Gigabyte, EVGA's fan profile is too aggressive when there's little or no GPU activity, resulting in idle noise level being noticeable. The fans' decibel rating looks good in the graph, especially under load, but they're certainly more audible than those present on other cards' - the pitch is a little higher than expected.

[Update] EVGA appears to be aware of the card's unbalanced acoustics and has released a BIOS update that it claims will "reduce the fan noise level while the card is idle."

We've tested this new BIOS, which updates the card to 82.07.25.00.53, and found that while the fan-speed is still at 42 per cent, the pitch is certainly lower. Our idle-load decibel reading drops from 34.4dB to 33.5dB.

The update to fan acoustics is the only change in this BIOS. Also please keep in mind it will not lower the minimum allowed fanspeed (42%), but the acoustic level will be lower. To update please follow the below instructions:
http://forums.evga.com/tm.aspx?m=2123961

You'd think a card with two fat copper direct contact heatpipes and two large 80mm or 90mm fans and a large heatsink would be less aggressive fan-wise than the stock aluminum finned heatsink that is half the size.

Your best bet is a simple BIOS tweak in Kepler BIOS tweaker (see http://forums.evga.com/tm.aspx?m=2051418)
