Description

NOTE: This device is intended only for advanced users with electronics experience. EPower board is covered by DOA warranty only. Use of this product will void your graphics or motherboard warranty.

 

EVGA "The Untouchables" EPower board is a separate VRM board to provide additional power for target devices, such as videocard, motherboard or other devices which may need high-current low-voltage power source.

 

Notes

The EVGA EPower board is designed to operate with two voltage outputs:

VCORE output - Voltage adjustment range of 800mV to 2000mV. Current source up to 400A.

VDIMM output - Voltage adjustment range of 1000mV to 5000mV. Current source up to 80A.

 

Recommended Toolkit

AWG12 or AWG10 Copper Wire with Insulation

60W or 80W Soldering Iron

Digital Multimeter for Resistance and Voltage Checks

EVGA EVBot with X58 Firmware

80 or 120mm +12V DC FAN with 3-pin header for VRM Cooling

Flux and Solder for Wire Joints

 

 

 

MSRP: $99.99

 

Same price as the EVBot

:welcome: ALL

 

Long-time awaited moment, thing that noone does before.

All-mighty EVGA's "The Untouchables" EPOWER available.

 

http://www.evga.com/products/moreInfo.asp?pn=100-UT-0400-BR&family=Accessories%20-%20Hardware&sw=4

 

EPOWER card is designed to operate with two voltage outputs :

 

  • VCORE output– Voltage adjustment range of 800mV to 2000mV. Current source up to 400 A.
  • VDIMM output – Voltage adjustment range of 1000mV to 5000mV. Current source up to 80 A.

 

Minimum requirements

Minimum 600W (42A on +12V rail) power supply with two or three 6-pin PCI-Express supplementary power connector cable for each EPOWER card used in system.

 

This device is intended only for advanced user use with basic electronics experience. EPOWER is covered only by DOA warranty

 

Basic usage guide:

 

1. Disconnect stock VRM power inductor on desired channel

2. Open copper plane for ground and power on target device

3. Solder thick (AWG10-AWG12) wires from EPOWER GND to ground and VCORE or VDIMM points to power.

4. Default startup voltage on VCORE – 1200mV, VDIMM – 1500mV. Maximum current for VCORE – 400A, VDIMM 80A.

5. Good rule to follow – one pair of wires (VCORE+GND) per each 10-15A. For simple VGA like with 2-3 phase VRM best to use 4-8 wire pairs. For high-end VGA should be no less than 10-15 wire pairs. Top GPUs like GF100, GF110 must use as many pairs as possible physically.

6. Multiple wires reduce voltage drop under idle and load states. If drop (difference of voltage between EPOWER card and GPU capacitor voltage near package) is more than 100mV – more wires are needed to compensate.

7. EPOWER card requires forced airflow under heavy load conditions. User can use onboard 3-pin FAN connector.

8. After connecting EPOWER to GPU always check resistance between power and GND to ensure no shorts. Normal resistance range for GPU is 0.5-10 ohm, for memory – 5-200 ohm.

9. For videocards with advanced PWMs (>3 phase) check VR_ENABLE signals and VR_PGOOD (power good).

10. Connect PCI-Express power to EPOWER card AND videocard. If you don’t use secondary power on EPOWER (3phase) you can leave “INPUT DIMM” connector not connected.

11. If after power on voltage is OK, but system does not detect videocard – cut VR_PGOOD trace near onboard PWM on videocard. This will prevent onboard VRM to reset GPU (because onboard power is not used – it’s fault state for it)

12. For voltage adjustment on EPOWER use EVGA EVBOT with X58 motherboard firmware. VCORE voltage is CPU Voltage, VDIMM is Memory voltage on EVBOT.

Retail price is $99.99 USD for this power monster. Shipping price not included.

 

Refer to EVGA's page linked above for ordering.

 

Some people already tried this unit during their OC sessions and had lots of fun.

by The Way. Has Anyone Who Tested This Thing Reported On The Clock Freq Gain?

 

+14,000,000,000. I really would like to see a proper before and after on a card that has been benched on it's own PWM a few times and the behaviour & MHz are KNOWN.

Yes ME, i used them and still use them, have them in the house and played already on gtx285 ref, 6670 ati and 8800gt

Okay I want one but where to buy in Europe? ;) eu.evga.com nothing available...

Don't have results of that, but what i still know is :

 

Stock VRM ref gtx285 Vmod LN² : max 945Mhz core, with Untouchy 1025-1050Mhz core

 

Stock ati 6670 Vmod LN² : max 1400Mhz core, Untouchy 1600Mhz core

 

8800gt died while benching with artifacts, but will be redone and more vga's to come,

 

have a 8800GTX, 9800gt, 8600gt ready for Untouchy mounting and benching, only looking now for better cpu SB +5700Mhz.

I used too long cables of poor quality so I had damm big vdroop, but I managed to do 1150 MHz GPU 3DMark 11 (the same as on stock crappy VRM - max of card, but with EPOWER I needed a bit more voltage cause of droop) but I in my opinion for strong GPUs like 580 EPOWER should be treated like rescuing GPU plan B (plan A - RMA it :E) rather than mod for MHz gain.

From what I've seen on OCF, no actual review before/after performance on the cards - just final results after the mod. Kinda OK, but everyone wants to know the before and after. The after doesn't mean shit if you don't know how good/bad the card was to start out with.

 

If you don't do before and after, its more marketing/PR than it is actual review/testing.

 

+1

I bet cards vary more from sample to sample than the extra PWM yields.

This is all the info the entire community has on "before & after" and it's only just been posted. I'm sure you can understand our frustration.
