Good day I've been having some problems regarding this Motherboard, its a Winfast K8M890M2MA-RS2H. I wish to upgrade my processor to a dual core so I tried to put an Athlon64 x2 5000. But there's no display just fan spinning. The bundled processor that came with the motherboard is a Sempron LE1150 and its working fine. I've visited the manufacturer's website and it clearly states that it supports am2 dual core processor like the X25000. I've tested the processor on another working motherboard and its ok and no problems.

The stock bios version is 641W1P41. I decided to update it to the latest 641W1P44 thinking that it may fix the problem, and its a dead end again. I tested all other components, cleared the cmos replaced each part that might cause the no display but still no luck. There's no jumper settings that points to a processor upgrade.Hope someone helps. Tnx a lot in advance!!!

the update bios version 641w1p44 is working fine with sempron le1150 and operates in normal condition.

Hi chickmazta
While researching the MB it became apparent that BIOS issues are well documented with this MB.
Couple of questions for you;
1: Is either the MB or CPU an OEM component as in are they out of a branded machine such as a Dell, HP, Compaq etc.
2: Are you using an add on video card or MB integrated video chip.

The CPU details can be found @ http://www.cpu-world.com/CPUs/CPU.html
There is a problem with the direct link but you can access the info from the CPU World homepage above.

Tnx sir phill, Both the processor and the motherboard are not OEM. They where purchased on a computer store a few years back for a custom build pc. I'm using an add on graphics card, leadtek 7300gs 256mb. This afternoon I'll redo all the test just in case I miss something. Are there any test I may include? tnx in advance.

Please try removing the add on video card and using the MBs integrated video chip, let us know how this goes.

I already found the problem. And I'd say this is extremely very rare. The processor's pin doesn't reach the motherboard socket to the contact point. I mean I need to push the processor down so hard so that the pin clearly stick to the socket, that's how I got it to boot even if its locked with HSF. Its either the processor's pin is short or the socket surface is a little thick than usual. I used sand paper to thin the surface of the socket making it a half mm thin. Does anybody encountered something like this?

[phillpower2]

Ive not heard of this before!
Is the lever that holds the CPU in the socket ok, is the locking tab that holds the arm down and in place bent perhaps!

[chickmazta]

That's what I was thinking too but I disassemble the whole unit and looked at the socket from any point of angle. And I see nothing wrong with it but of course except for the thick surface that I just recently trimmed. I've used 3 other processors and its working fine with this motherboard. And I've tested the processor on other boards as well. Which of the two would be considered as defective?

Sorry I can`t honestly answer that I`m afraid.
