Easy to install. Easy to follow instructions. Works terrific! Exceeded my expectations. Overall a great pick-up for anyone into gaming and music. Price that its offered at through dell could be better. I paid 109.

Easy to install and fantastic improvement on my Inspiron 530. Flight Simulator Acceleration is way much better to play now. I upgraded my XPS 400 with this graphics card and 2 more additional GB of RAM. There was a noticeable difference in speed.

BIOS setup screen L

Genie BIOS settings: This setup thread is combined all needed settings for over clocking (CPU speed setting, CPU features, DRAM timings, Voltage settings and PCI speed etc.)
Genie BIOS : Main setup screen
OC Fail Retry Counter: 0~3 times OC fail retry looping setting. For example, set it on 1, it will retry boot again if fail, then auto back CPU default

value to boot system.

OC Fail CMOS reload: Disable / Bank1~4 Assign bank settings reload for boot when OC fail
CPU VID Special Add: (+12.5mV~+787.5mV)
DRAM Voltage Control: (1.800V~3.375V)
CPU VTT Voltage Control: (1.20V~1.55V)
Core Aux+1.2V Dual: (1.19V~1.66V) (Chipset Core voltage)
Core VDD Voltage: (1.199V~1.387V) (Chipset Core voltage)
GTLVREF Lane0~3: (-155mV~+155mV) CPU data bus data reference voltage level, reducing it will help getting correct data deliver in highest DRAM speed. To increase reference level can reduce highest frequency noise effect.
CPU Clock ratio: CPU multiplier setting, 6~11 for locked processors, 6~50 times for unlocked processors
FSB & Memory Config :
FSB Memory Clock Mode: Auto, Linked or Unlinked mode
This is usually either auto, linked, or unlinked. If it is linked, you can set your memory ratio. If it is unlinked, you may set the memory clock to whatever you feel like.

* Linked mode:

FSB Memory Ratio: Auto, 5:4 / 3:2 or Sync Mode (1:1)
FSB (QDR), Mhz: 400MHz ~ 2500MHz (FSB 100Mhz~625MHz)
MEM Power Feature: Enable / Disable
Power management solution, It comprises a step-down controller, a source-sink LDO regulator, and a reference buffer to generate the required VDDQ, VTT, and VTTR rails.
Advance Path: Auto or Enable / Disable
Provides the lowest latency data path for memory writes and reads within the chipset
ADSTB: Auto or manual 0~3
External latched timing. In memory-to-memory operations, data from the memory comes into the DMA controller on the data bus during the read-from-memory transfer
Budget: Auto or manual 1.50ns~3.75ns
Delay budget timing for memory operating

* Unlinked mode:

MEM (DDR), MHz: 400MHz ~ 1400MHz

Memory Timing Settting :

Memory Timing Setting: Optimal / Expert mode
(tCL): Auto or 1~7 clocks; CAS (Column signal) latency time (tRCD): Auto or 1~7 clocks; RAS (Row signal) to CAS (Column signal) delay for read/write command (tRP): Auto or 1~7clocks; Precharge timing for memory data by each command cycle (Tras): Auto or 1~31clocks; Minimum timing of a command working cycle. (TRCD+CL+ 2 clock) Command Per Clock: Auto or 1T~2T; Command Rate
(tRRD): Auto or 1~15 clocks; Command rate of memory's banks (tRC): Auto or 1~31 clocks; Minimum timing of a command to next command. (tRC) = (tRAS)+ (tRP) (tWR): Auto or 1~6 clocks; Write recovery timing (tWTR): Auto or 1~15 clocks; delay write to read command for memory chips (tREF): Auto or 7.8/3.9 us; DRAM chip reflash cyc

Onboard GPU: Enabled If No Ext GPU / Always Enable Enabled If No Ext GPU Auto open onboard display if no display card inserted when if it detects a extra display card inserted, onboard display will be disabled.
iGPU Frame buffer Contorl: Auto / Manual

Frame Buffer Size: 256M / 512M
Retain PCIE dev to Gen2: Auto / Disable
These applications may want to retain flexibility when specifying the operating port type in the device configuration stage. Such applications need special PCIe logic implementation to support both root port and endpoint configuration models and different configuration register sets. This dual mode supports results in increased transactions and configuration register block size; however, the additional cell count is usually outweighed by the achievement in solution flexibility.
System BIOS Cacheable: Enable / Disable
BIOS Reloaded function: DFI Lan Party series are providing 1last fine status + 4 users profile space for doing BIOS setting saving and recovery.
Auto Save bootable setting: Enable / Disable For saving last fine/ bootable parameters by BIOS itself every time
Load last bootable: For loading last BIOS parameters.
Save setting to bank with: Current settings or last saved CMOS settings. To define the resource of parameters for bank saving.
User define setting bank #1 ~ #4: 1. Bank Description: There are 4 rows for writing a short description. Double click on row when this row is empty, it will erase pervious data.
2. Save to this bank: Press Y to save data to this bank 3. Load from this bank: Press Y to load data of this bank to be current BIOS setup settings. 4. Hotkey =>: define the hotkey for quick change BIOS settings to boot. Please press Hotkey after power on system immediately.
