Set MCH to 1.2-1.3 and set your ram voltage to 1.8 manually or 1.85-1.9

Default Re: Problems with GA-EP43-DS3L and 2x2GB memory

Hey, I'm new here and I'm in dire need of some help!

I have a dual core 2.8ghz processor (not sure about anything else on it, I got it from a pre built comp), 2 gigs of corsair PC2- 5400 675 mhz ram and a 500 watt PSU.

I have everything plugged in and I get the whole continuous reboot jazz...

I played with the ram, one stick rather than two, tried using different slots all combinations and no luck.

I then unplugged the 12v CPU cable and it stopped rebooting, but it also didnt post.

I'm not hot on computers at all, I just managed to build one but the mobo died (dodgy line of Asus P5K boards) so I swapped to this one and accidently opened a new can of worms...

Does anyone have a clue what it could be?

The computer doesnt even post, never, not once. I've left it cycling through the reboot process for 5 minutes straight. It fires up, 3 seconds later it reboots. Its doing my head in!

Default Re: Problems with GA-EP43-DS3L and 2x2GB memory

Hi Lsdmeasap, I would greatly need your help. Just bought my new PC and found out that it's not stable when running DDR2 2GB dual channel. The symptom is my PC will freeze/hang anytime. I've tried with games like CoD:WaW, NFS:Undercover; it'll sure hard freeze when in-game in few minutes.

Solutions tried:
- update the BIOS to F9a
- tweak DRAM voltage[1.9V], MCH core[1.2-1.3V] (even more unstable, system rebooting)
- sometimes freeze in BIOS when running dual channel
- all hardware settings reset to defaults (doesn't resolve)
- install different OS (Vista x86 & x64) (not the root cause)
- run memtest (sometimes freeze also)
- remain only 2GB DDR2 in a slot (works fine in windows, but still freeze in game)

My PC specs:
Intel Core 2 Duo E8400 3.0GHz/1333/6MB
GA-EP43-DS3L
Kingston DDR2-800 2GB (valueRAM) (2GBx2)
Gigabyte ATI Radeon HD8450
Silverstone PSU 500W
Seagate SATA 500GB
Vista Ultimate x86 & x64 (tried both OS with the same problem)

BIOS Settings: (these are the settings from "Load Optimized Defaults")
Code:

Questions:

- will the coming full version of BIOS fix this issue? when will it be available?
- anything else can be done if your recommended settings still doesn't solve the freeze problem?

cpu: e8500
gpu: ati4850
ram: g.skill f2-8000cl5d-4gbpq [2GBx2] ddr2-1000, pc2-8000

worked in dual channel for about 2 weeks. both ram sticks are tested with memtest, and work fine, tested them seperatly.

today i got a cpu freeze and after rebooting, the mainboard keeps beeping (award beep for no memory found/ wrongly seated memory)

when i start with one stick, it boots just fine, when i boot with both sticks (slot 1/3, 2/4, 1/4, 1/2) the mobo just beebs and goes into a reboot cycle.

these are optimal default settings, should be newest bios, did the auto updater.

Hi ,
I had the same problem as Drose and after reading and following Lsdmeasap's help notes , I got my system to run on all cylinders ( I mean RAM) . So a great big Thank You to Lsdmeasap, it proves Forums work !
