can only boot by pressing mem ok!

[vishalg]

i am able to boot only by pressing the mem ok button (twice) on by asus m5a97 evo board, it gives continuous 1 long and 2 short beeps and the dram led on the board is lit.

i have 2x2 gb corsair ddr3 value rams @1333

1. i have tried clearing cmos by jumper as well as removing the battery.
2. tried booting with single stick of ram
3. cleaning the contacts of ram sticks
4. tried different slots
5. have manually entered the ram timings

but everytime i shutdown my pc for say a few hours, the problem reoccurs

Why don't you revert all the BIOS settings to the original values?

Take out the ram, then re insert it, happens to me every time I clean my pc and remove the ram, asus boards are very sensitive to ram connection.

1. Power your PC off completely.
2. Take out the RAM modules.
3. Reinsert them.
4. Press Memok button for 5 seconds.
5. Start your PC.

already did that by clearing cmos

did that several times and also cleaned the contacts

1. Power your PC off completely.
2. Take out the RAM modules.

4. Press Memok button for 5 seconds.
5. Start your PC.

you mean to say press mem ok before powering on??

Keep pressing the memOk button and switch on your PC till your RAM gets detected and system boots. Then restart again and check.

Did it work?

Yes!!
MemOK button should never be pressed while the motherboard is powered up.

did so, but the pc powered on by just pushing the mem ok button.
is this normal?

although it booted up fine after some days again the same promblem occurs

Yes!!
MemOK button should never be pressed while the motherboard is powered up.

i used to press it with the pc powered on and booted

can this be due to any grounding issues, coz one of my mobo standoffs(brass) is not properly fitted to the chassis

 

[d6bmg]

Press memok button in the process I've already mentioned. Your problem will get solved I think.

 

[vishalg]

did the above but the problem remains, each time i boot the system after few hours it beeps with mem ok led on

i have to press memok button each time to boot, this is really getting annoying now

 

[d6bmg]

^^ Well, then send the board for RMA. It is motherboard problem.

 

[sumonpathak]

^^its 1.65V? yes? tried setting 1.5v in Bios?

 

[vishalg]

no its 1.5v
i am posting the cpuz screens for what the memok has set!!!!!!!!!!!!!!!!

 

[d6bmg]

He meant to say set the DRAM voltage manually in the BIOS to 1.5V.

 

[vishalg]

yes it is already set 1.5v only, did you look at the crazy timings the memok has set?

 

[sumonpathak]

try 9-9-9-18 1.5v manually...the timings are not crazy per se...at about 444*2 its supposed to run at that settings....

 

[vishalg]

ok, will do and report

 

[vishalg]

that didnt help either
everytime the system is powered off for few hours it will only boot after pressing memok
its like bios cant remember timing setting

 

[sumonpathak]

erm.....is the battery ok?
