Gigabyte 5870 SOC

[Raja@ASUS]

TT Sense works with a NTC thermistor - it should not affect the cold temp throttling at all really because NTC thermistors will hold their resistance high well into the sub-temp threshold (that's why they're NTC ). This prevents excessive sinking of the 122ua to ground, thus keeping the voltage at the comparator above the throttle threshold. I doubt lifting that pin will do anything in this case, although I guess you're free to try.

[BenchZowner]

We ( well, at least I ) don't know the location of the thermistor, could be near a hot source, won't make a difference more than likely, but I do remember saying such things in the past and the results proving otherwise

[Raja@ASUS]

Try it then I guess. Most NTC thermistors will hold their resistance beyond -75 Celsius without a problem.

how can i use gigabyte soc tuner for my vga ?
the vga is gigabyte GV-R5870D5-1GD-B

You can't.
This tools is made for the Super Overclock edition which carries different PWM controllers.

No matter what you do, it won't work.

how can i give voltage to memory?

[BenchZowner]

Only with a hard mod, and if it uses the standard Samsung memory chips you will gain nothing with higher voltage.

[Bodar]

So there is absolutely no way to change the voltage through software.. Ab or anything at all? I already hard modded my mobo.. If the mod actually helps then I guess it's worth it otherwise a no go for me..

[BenchZowner]

Others seem to be able to change the GPU core voltage with the software I linked.
My card didn't ( funny, I'm the only one ).

Afterburner ? for sure no.

Try the tool I linked.

There is using OC Guru. Vgpu up to 1.30v and Vmem up 10 1.70v.

He was asking about a non-SOC card

[Bodar]

Is there a way to change the oc guru software to get 1.5v or 1.6? I've managed 1.5v on a regular 5870 through software before.. thanks so much! Sorry I forgot to mention it's a retail SOC

[miahallen]

Yes, do the VID mod posted for 1.5V....then OC Guru will default to 1.5V and allow SW adjustment up to 1.6V

[Jor3lBR]

Mia,
If the VID mod overvolts by 0.5v all I need to do is perform the 1.40vid mod and this will be raised up to 1.55v thru OC Guru?

[miahallen]

No....OC Guru only allows an additional +0.1V added to the set VID Set your VID on 1.4V and you'll default to 1.4V, OC Guru will allow you to raise that up to 1.5V

[Jor3lBR]

I read somewhere here that either you or benchzowner where having 0.5v of overvolt? So if the vid was set to 1.55v you were at real 1.6v?

[BenchZowner]

Yes, that's correct.
Mine and miahallen's (?) card overvolt by 0.05V, so if you do a VID mod for 1.35V you'll get 1.4V, etc.

[DEVIL K-ce]

I make fb mod with 20kOhm and vgpu def is 1.25v, with soft You can push it to 1.35v. But my problem is ... at stock cooling and stock MHz I get freez in any 3D bench, when I push some more voltage then I can close to 1GHz on gpu with air, on ln2 with 1.4v I cannot complete any 3D bench with temp -100C or sub @ 1150MHz on gpu.

I think MSI card is mouch better than GB SOC.

[miahallen]

I only got an extra 0.05V when I did the 1.55V VID mod (so I got 1.6V actual).
When I did the 1.4V VID mod, I got 1.4V actual

From what I understand, the FB mod will not adjust OVP...the VID mod will

[BenchZowner]

Exactly what miah said DEVIL.
I'm quite sure that you're getting OVP'd.

[DEVIL K-ce]

Ok, but also without mod and on any cooling solution I have freez in 3d test. With voltage adjust only from software card cannot complete bench at 1GHz.

[Jor3lBR]

Sorry to hear about your sample man, mine passes PCMark05 Graphics Suit with 1050Mhz/1350Mhz on stock volts.

[BenchZowner]

If it crashes at default clocks and the temperatures are normal, then I guess an RMA is in order.

[massman]

Tested another sample last weekend with Marc Beier: 1300/1375 Vantage stable.

No coldbug, but sadly enough the card wasn't scaling with voltage at all. Just a bad sample, I guess
