Great single monitor card – WARNING FOR DUAL MONITOR USERS 07/09/2010
I replaced two older Nvidia cards with two GV-N470UD-13I cards on a non-SLI, multi-monitor system running Windows 7 (64 bit). Despite NVIDIA related issues, the card and associated features are great on a single monitor system.
-Exceptional rendering/GPU processing performance in Premiere CS5
-Exceptional performance in Master Collection CS5 and Windows 7
-Best graphics adapter packaging I have experienced
-Caps on all SLI and DVI connectors
-Quality HDMI cable included
-Ultra-durable component series
-Well written user’s manual and software
-3 years warranty without artificial constraints such as registering within 30 days
-Direct/quick RMA support
-Free tech support (answered in less than 3 minutes when I called)
-Shorter card length allowed access to SATA connectors on my motherboard without having to remove the video cards
Cons with the card were unrelated to Gigabyte and Newegg, so I am giving this card 5 eggs for a single monitor system.
Long story short, I inevitably discovered that enabling the second monitors on each card kicked the GTX 470 idle/2D Desktop apps temps up from 40°C to 82-85°C. This is roughly 48% higher temps per card (i.e., 104°F vs. 185°F per card), and would correspond to about a 43% increase in the systems idle power per card.
Again, I am talking about idle state and not under load. In context, my Intel Core i7 Extreme 980X runs idle at 25 °C and my older 200 series video cards run idle at about 28°C
After investigating and confirming with Gigabyte technical support, I discovered that the NVIDIA 400 generation suffers from flickering with dual monitors at lower memory MHZ. This problem is attributed to the GDDR5 memory and NVIDIAs ingenious solution was to simply disable memory down clocking and let manufacturers fix it later.
Thus my problem, a second monitor = NO memory down clocking = immense increases in idle thermal, power and acoustics for GTX 400 cards until this problem is fixed
I would have been fine with 40°C to 50°C idle and 2D desktop temps and 80-90°C load temps; however, a constant 80-90°C per card across a 10-12 hour days that entails mostly 2D apps and bouts of computer idle time was not an option for me, so I returned the cards.
The Gigabyte technical support rep actually recommended that I return the cards until the problem is corrected based on my two card & 4 monitor configuration. Would have recommended keeping if one card or one monitor per card. He also described that they were within months of a bios fix for this NVIDIA bug/defect.
Newegg support is great...
