What 750Ti do you have? Asus? EVGA?

What does your memory max out at btw? I've heard some bad stuff about memory OC on 750Tis however mine seems to be able to bench at 1625MHz (6500). Though I'm not quite sure if that's good or not.

evga ftw

Btw my rams bench at max 1700 but 1650ish for all benches is best.... forget it gaming thuo 1400ish is all in bf4:eek:

Ok does not want to flash on my p67 efi or legacy board but flashed fine on my z87 board.
First i tried the modded one in that cypto blog but no boot on my evga ftw card so i modded mine the same way and now 1.19v with the dmm
the bios i know is good for this card not of others so dont chance it make your own with kbt

evga 750 ti ftw 1.2v 3d .96v 2d.rom

Pulled the trigger on the PNY Ti OC
:wheee:


Props to AlphaC for the PCB explanation and Mining info that led me to the decision!

It's always exciting getting a new card. Or anything new that's computer related for that matter.

Are you flashing using the nvflash linked in the owners thread? Are you disabling protection first?

Nvflash.exe - - protectoff

Then

Nvflash.exe -4 -5 -6 Asus.rom

I am using this KeplerBiosTweaker and this DOS version of nvflash.
http://cryptomining-blog.com/wp-content/files/gtx-750-ti-power-limiter-mod.zip

windows version of nvflash did not work for me.
I created a MS-DOS bootable usb drive using Rufus
In Rufus, choose MS-DOS, not FreeDOS. FreeDOS did not work for me.

only DOS commands I use are
nvflash --list
nvflash -save [name_of_bios_to_save].rom
nvflash [new_bios_to_be_written].rom

So far, I increased the power limiter but did not like the results.
Much higher voltage and higher gpu temp.

Alternatively, I would like to decrease voltage and not increase power.
For reasons unknown to me, I can not save voltage decreases with KeplerBiosTweaker.
In the voltage table, I decrease voltage of CLK 52 to CLK 60.
But when the bios is saved, the voltage reverts back to the original voltage
Please help me to decrease the 3D voltages in the voltage table.

Initial results: PNY GTX 750 Ti OC

Core: 1359 MHz (Valley read 1476 MHz when running, although I can't figure out how to get a screen of that.

Max core temp was 63C after a 30-min initial bench.

I'm amazed at this card. It's just what I wanted; low power, could fit in my case, and can crank out my games and CATIA work without crying.



Since my last card was a 6970, I'm very happy!

Hey guys. Finally found this thread
redface.gif
Figured it was a good place to ask about, first of all, a modded BIOS. I heard it just raises the power limit. No 1.212v? I have 2 EVGA FTW's and have been mining at 1363mhz/6000mhz, and one is at 1.175v, the other is 1.15v. Would love to see what they can do with a little higher voltage.

Also, if anyone knows what config/flags to use for CUDAminer? I been using the auto-config, getting almost 300kh/s on each so far. Not sure if there's anything I could change that might help though.

hello to all,
I have a palit stormx oc, I wanted to flash the bios of the palit dual stormx c that seems to have the same pcb, only 5,163 with nvflash does not work for me, it crashes immediately after the command, someone with a palit could try to see if it works?

Houston we have a problem I maxxed the slider 135

Made a bios on the fly with 1700 max boost but dont know if it works i could not flash it on this board 1490 max boost 1.2v -30c its got more for this bench i could run this clock for all day uses hardly any dry ice

Awesome! Time to go cold, seems like it will save LN2 usage running with no cold bug IvyB-e which drink ln2 for lunch

Yeah you should save alot of ln2 with this card

the mount was a pita thuogh needed zip ties for it cb cbb tested only to -40c was a ok


playing bf4 at 1470 np

..... well dying alot:p


ultra and ao set to quailty is too much for it setting to high is better
will try more sub zero later today:)

Galaxy GC is Hynix BFR (not AFR) not Samsung : that's quite disappointing

Now according to techpowerup I'm missing:
ELSA GTX 750 Ti S.A.C (short PCB so not hopeful on this one)
EVGA GTX 750 Ti Superclocked (most likely reference)
Gainward GTX 750 Ti (short PCB)
Gainward GTX 750 Ti Guan Edition (I've not seen it on geizhals so I don't know if this is going to be available in the Western Hemisphere)
Galaxy GTX 750 Ti OC (low profile card , no 6 pin, this is the card to pay attention to for HTPC use)
KFA2 GTX 750 Ti OC (should be the same as the Galaxy OC card ... low profile , no 6 pin)
Leadtek WinFast GTX 750 Ti (short PCB , likely reference)
M-ONE GTX 750 Ti Worry-Free Edition (likely only in Asia)
Palit GTX 750 Ti StormX OC , PNY XLR8 GTX 750 Ti --- seem to be very similar, short PCB
Yeston GTX 750 Ti Game Master --- no hope getting this outside of Asia probably
ZOTAC GTX 750 Ti --- short PCB, no 6 pin : likely reference with d-paks swapped out for Low(RDS)on mosfets & ferrite choke instead of iron choke

ZOTAC GTX 750 Ti Thunderbolt

Geizhals has an ASUS GTX 750 Ti (GTX750TI-PH-2GD5) with single fan also , it looks to use the cut down GTX 750 PCB (no 6 pin, 2+1)
