just installed AMD Bulldozer X8 FX-8150 but sytem not seeing all memory? it says 3gb 1.98gb usable?

I assume you're using the 64-bit version of Windows. Just enable 'Memory Remap' in your BIOS. Having 1.98GB of usable RAM sounds a bit weird, post a screenshot of the memory tab in resource monitor.

I hate to say but checking your mobo spec's, it doesn't support the FX chip set.

i have a GA-970A-D3 and dont see that feature in the bios.

do i have to reformat the hard drive??

 

[linnemeyerhere]

My bad I cut and pasted the mobo spec and it took me to Gigabyte. Let's try this again !

I'm still not seeing your chip on the list!

 

[linnemeyerhere]

What is your bios version?
It appears you have a F3 version bios for the Athlon and need a F7 version for the new chip bulldozer.

flashed F11 and i think i did something to the memory slot cause i took one stick out and system did not boot up, tried one single in the other slot and booted up. tried both in another slots and it sees 4gb now. nut not dual channel? What about if a cpu pin was bent? But it would'nt luck down in the scocket?

 

[linnemeyerhere]

Can you take a picture of the ram slots and ram. What makes you think that the CPU pins could be bent? you mentioned it and that concerns me. When you drop the chip in.....zero.....I mean zero force should be needed to seat it!
Looking at the manual and your ram slots are color coded 1-2 blue and 3-4 white so please refer to below.

I mentioned the bent pin as some one stated that it may be a cause of the memory issue from another forum. I have 4 verticale slots from left to right- ddr3-4 , ddr3-2 , ddr3-3, ddr3-1 the manual suggests to use ddr3-1 and ddr3-2 for dual channel. Thats were they were and working before. ddr3-1 slot works with a single stick where as ddr3-2 i get no video picture when unit boots up. Same as the slot beside it ddr3-4 doesthe same thing. the other to the right work ddr3-3 and ddr3-1

in my manual ddr3-4 and ddr3-3 are blue and other two are white. my memory has always been in the white.

 

[linnemeyerhere]

Well in the end you have the ram being seen and that's the important thing. Maybe you have another 2 matching sticks in your future for a 8 gb system or another 4 sticks of 1600 or 1866 Mhz? Ram has fallen in price and 8-16 gb is a nice zone.

 

[andjayik]

but now the proper dual channel slots can not work together. I may go get a single 8gb and run that as ganged single dual channel?

 

[andjayik]

gigabyte said that the motherboard does not support the cpu. But i got one 8 gb stick working. Looks like i have to get the next board up. any one want to buy the board?

 

[andjayik]

well just bought a sabertooth 990fx and 8gb of patriot ram and i still get that memory issue??? cpu faulty?

 

[linnemeyerhere]

Doubtful it's the memory. Can you take a picture of the error you're getting. You installed the new Sabertooth (nice mobo!) and I would use only one stick of DDR3 to then do a clean install of Windows as I don't believe you have a chance of using your current W7 from the install of the previous mobo.

 

[andjayik]

ya i did do a clean install with the new 8gb in and still this?

Its got to be the cpu???

 

[linnemeyerhere]

Everything else is good, your booting but not getting all the ram installed to be usable?

 

[andjayik]

correct and cpu does'nt seem super fast?

 

[linnemeyerhere]

Have a look at this and see if this doesn't help with the memory issue?

[andjayik]

did nothing

 

[andjayik]

so can a bad pcu effect 2 slots of ram? working in 2 and not in the other? pc is not as fast and kinda hangs waiting for internet to connect. Same symptoms on 2 different boards and ram. Thinking of taking cpu back and getting a exchange.
