I am using OCZ RAM (OCZ DDR2 2GB kit OCZ2N800SR2GK) , from last one year without any problem SLI enabled in BIOS MAX CPUOC everything set to AUTO nothing overclocked suddenly all just happend. system crashing BSOD's can anyone tell what problem causing it all suddenly. now whenever i enable SLI mode in BIOS, system wont BOOT hangs on POST screen. Disabling SLI works but after using system for sometime BSOD.
This could be for several reasons, including the power supply going bad. Check to make sure all of your fans are clean and operating. Make sure have good airflow and that nothing is blocking your fans to the maximum extent possible.
If the inside of your case is dirty, get some canned air and blow the system out, making sure all of your heatsinks and fans are clean, as well as any fan grills.
If these steps don't stabilize the system, try to swap your power supply with a known good PSU that meets your system's requirements to see if that does the trick.
PSUs, even very good and expensive ones, fail. When they do, they often cause the very symptoms you are experiencing. I keep a spare PSU on the shelf for just such times.
Based on your system's history and symptoms, a new PSU is likely in your future.
Checked everything.. fans running properly no dust(one week back cleaned UP whole system), CPU fan okay all fans working at normal speed.
one thing i want to know why SLI enabled not working in BIOS suddenly thats the main issue arise... when i enable SLI in BIOS system just hangs in BIOS post messages
[BTW whats the relation between PSU and SLI RAM]
CPU: Intel Q6600 revision: B3
PSU: Cooler Master real Power Pro 850
A bad PSU can be sending inconsistent power to the system's various devices, particularly the GPUs. That could cause the SLI issues and the inconsistencies you seem to be having with your memory. I assume all was well for some period of time and now the system is unstable? Is that correct?
one thing i tested when i set 4-4-4- TRAS-15 Command Rate- 1T, memory Volts Auto and Manuall Set 2.00 both tested BIOS Hangs and same 4-4-4 tRAS-15 Command Rate Auto and Memory voltage Auto system boots UP perfect
Re-read the entire post, so lets start over. Until recently, your system had been stable. What, if anything, changed just prior to the system becoming unstable? In your original post, you said something about going back to version 1305 BIOS. What version had you been using when all of this started?
What other hardware is installed in this system and what flavor of Windows are you using?
Got it. I assume the new BIOS version didn't fix anything so you reverted back to the original BIOS.
Either you mobo or RAM seems to be flaky given that you ruled out the PSU as the possible problem.
Have you run memtest to verify that RAM is good? If not familiar with memtest, you can download Ubuntu Linux and run memtest from the CD by booting from the CD and selecting the proper option (it will be evident).
Do you have any other RAM that you can swap into the mobo to check out stability of the mobo?
ok tested 1 week with my kingston value select 4GB kit RAM, no BSODs and no crash i think there is some issue with my OCZ RAM (OCZ DDR2 2GB kit OCZ2N800SR2GK) need to buy new OCZ 4GB OCZ SLI KIT or can you suggest me some best compatible RAM for my board
