GA-EP43-DS3 bios settings help

Artzone · 23 May 2009 at 13:10

I'm struggling to get my Corsair memory working with the Gigabyte GA-EP43-DS3. It's not on their official support list but it should work right?

It'll boot and the memory is recognised but Vista is behaving oddly. Taking ages to open winodws, close programs etc.

Motherboard: Gigabyte GA-EP43-DS3, Rev 1.0, Bios F9
Cpu: E8200
Ram: Corsair, Part# TWIN2X4096-8500C5, http://www.corsair.com/_datasheets/TWIN2X4096-8500C5.pdf
Power Supply Unit: OCZ 500W Mod XStream Pro PSU

Here's my current settings, most stuff was set at auto. I'm not looking to overclock for now, just looking for a stable system...

Set DRAM Voltage to 2.1v.

Then change -

Standard Timing Control
CAS Latency Time -------- 5 ---------- : [Auto]
tRCD ------------------- 7 ---------- : [Auto]
tRP --------------------- 7 ---------- : [Auto]
tRAS ------------------- 24 --------- : [Auto]

to

Standard Timing Control
CAS Latency Time -------- 5
tRCD ------------------- 5
tRP --------------------- 5
tRAS ------------------- 15

Thanks, done that, got a blue screen in Vista first time it booted, second time looks ok. Anything else I should change?

Artzone · 23 May 2009 at 13:34

Oops spoke too soon, another blue screen with a memory management error

Try 'Performance Enhance' on Normal or whatever the nearest setting is.

Could try upping 'MCH Core' by 0.05v.

Ok tried that, still getting BSODs, last one was system_service_exception.
