Evga Untouchables Rev0.1 testing on GTX285 + other vga's

then buy a Evga EVbot for high quality.

Messing with feedback with plain resistors is never high quality, it just "good enough" to work for some cases.

Best is VID/digital control, no matter Volterra, Intersil or CHIL/IR, because voltage control affects lots of domains inside PWM, like droop compensation, overvoltage, overcurrent protections, error compensation and efficiency. That's why EVBot exist, and why modern PWMs all have digital control and adjustment.

Do you get paid every time you mention an eVGA product, suggest someone buys one, or try to talk one of their products up?

[Chillerzero]

you are talking about changing PWM, Voltages other then a EVbot, but still you whant high quality adjustments?
But an Trimmer is not good enough?

Read what Tin says 2 posts above, that just says everything, nagging that a Evbot costs to much etc,
then you shouldn't buy a Untouchables, because you also need a soldering iron, caps, and some other stuff of HIGH Quality.
It all cost money even the low quality trimmers.

I wish i got payed every time i say : EVGA hahahahahahahahaha :p

I never said anything about trying to bypass the eVBot My point was that, basically, I would not trust a 10 ohm trimmer because it's so close to a short circuit. If the wiper slips, it's game over. For 10 ohms, for satety, I would wire up a set of jumpers and add either a 1 ohm fixed resistor or a short, depending on what output I wanted. Noise hell? Yes. Do I trust it to not fail? Yes.


My problem/concern/hesitation is that here is a product designed for low-end GPUs that costs 6-7x as much as the card.

I would like to see eVGA have MUCH better availability all over Europe, that way, inter-shop price wars came help the consumer. At the moment, the availability of some products is so bad a shop can charge as much as they want for it because there is zero competition. That doesn't help eVGA either in terms of sales ("it costs HOW much? Not buying it") or bottom line (eVGA sells to distro for X, by the time it hits retail, it's gouged to 50% higher than X.)

This is 2/3 off topic though

[Chillerzero]

i'm in europe to.
And yes Evga Stuff needs to be better availbale in europe indeed.

This toy is for overclockers minded, normal it cost more then a low-end cheap ass vga lol.

Puts a smile on my face every time I see these in action

Just avoid using the trimmers for voltage if you can help it dude. Not worth messing with the FB loop gain, screws with the reg performance. Unfortunately some people don't grasp this, but I know you can so... Evbot is really the best way.

Every time when i have it in action i burn my fingers of soldering it on vga hahahahahah lol ^p :p

[sin0822]

yea honestly, doing all those mods isn't really that fun to do, the PWM one probably wont be so easy. Id prob buy the evbot to save more hassle, but for those who can't afford it there is another way.

[Chillerzero]

evbot is only 50 bucks
