x2 4600(939)? only one core.

Tags:
Last response: in CPUs

ok here goes.

we installed an x2 4600 socket939 into my brothers
msi k8neo4 sli mobo. It previously had a 3500clawhammer.
after the cpu swap it booted up fine no windows reinstall or nothing.

windows and cpu-z only shows one core.

have tried bios update,reinstall of widows,amd dualcore optimizer.
and just about everything i can think of.

any ideas.

i can post pics and more info if needed.


edit; also ran a few multicore benchmarks which resulted in
only one core running.

thanks.

Have you tried the cpu in another motherboard, because if the bios is updated it means one of two things, either your cpu is bad, or you mobo is bad (which I'm guessing since you have also tried reinstall of windows)

Just wondering, how'd you find the time to post 5k reviews in only a few months?


Thats a good point, how did you post 5K+ reviews in such short time?
Or is it just a system error?

Anyway, during the initial post screen when starting up your PC, can you see if your BIOS detects it as a dualie? (eg. At the initial boot screen just above my memory capacity / cas latencies, my DFI board will say it has a 4200 X2, 2 CPUs)

Windows as in the Hardware installed section or the Control+ALT+DEL method??

Regardless of what CPU-Z says, press Control+ALT+DEL and in CPU usage ~ do you see two CPU cores being monitored??

I guess since you tried just about everything, and I'm guessing that the control alt dlt won't work considering that cpu-z registers it as single core, but just wondering, does cpu-z atleast register the processor as an x2 4600, because if it doesn't, then it is a mis labled chip and you deserve an rma. Ever way, if the chip doesn't work in a seperate motherboard (try a different company, I never liked MSI, I have one myself and its pretty crappy) as different companies have different bioses, and it might just be that MSI doesn't support the 4600 the same way that when the asus crosshair came out it didn't accept the 4600 either. Either its the board or a growing trend that the 4600s have problems

I highly doubt that one core is dead, cpu companies, unlike most others, generally do not have a lot of doa products, though there always is the possiblity. As i said before, what processor does cpu-z register it as?

When I switched from single to dual core, the AMD X2 driver appeared to install but instead stuck with the single core version. Try going into device manager, uninstall the AMD CPU device, reboot, then cancel if the cpu is detected and it wants to install the driver. Then run the X2 installer.

In answer to your other question, OEM does not matter.

maybe.

my 3700 to 4400 swap went fine but it was on my asus mobo
my brother has the msi with 3500clawhammer.
and the swap to the 4600 manchester is not so good so far.

right now i have my brothers computer ready, but am having
to wait for my girlfriends sister to get off mine. :evil: 

Oops messed up my post.

I just thought of something, have you cleared the cmos? because that will cause your motherboard to remember its previous parts and switching from single to dual core coudl cause that problem

actually no that is the one thing i havent tried.

i am setting here looking at my brothers computer
with hsf off waiting for my girlfriends sister to get off my computer
so i can try a swap with my cpu, im currently on my g/f,s dell

but i guess i could shut this dell down and reinstall the hsf and try that.

OK, FYI my devicxe manager lists two items under processors.

AMD Athlon(tm) 64 X2 Dual Core Processor 4200+
AMD Athlon(tm) 64 X2 Dual Core Processor 4200+

If yours shows 2 entries, bios and driver's ok

no it doesnt show that, only one.

Usually you will have to do that beofre changing parts in your computer while keeping the motherboard.
If it works, glad to be of somehelp, if not,sry, guess there's nothing much beyond that I know. Try asking Dasickninja, spud, uber_g or Jumpingjacj. There my friends and know a lot more beyond me. Especially jumpingjacj (who is already in this fourm), he probably knows

Guess its rma time, either that or try resetting your cmos as I said

OK, try uninstalling one more time then install the new one BEFORE rebooting. Win XP may have grabbed the old one on reboot before you had a say in the matter. Even better, go into the device manager, find the filename of the driver in use, uninstall then do a search on the driver file and delete all instances of it so windows cannot go and get it. then install the new one.

thanks for all the replies but i found the problem.

the mobo is it.

msi k8neo4 sli will not recognize the x2 dual core.


Did you check to insure you are running the multiprocessor HAL in windows? Swapping the dual core in for a single core doesn't automatically change this and I don't believe installing the AMD driver changes this either. If you're not running the correct HAL, you will see this issue as well I believe. If you look in device manager and expand Computer, (on the box only reporting 1 core) what does it say? If it says anything Uniprocessor in there then that's your issue....(i just skimmed the thread so if this has been tried ignore it...)

AMD dual cores need bios updated, a microsoft hot fix, and AMD's dual core patch to work correctly.

EDIT: oops, sorry -- did not see you already tried that.... out of ideas :)  :) 


Wrong.

My dual core was recognized right on by the BIOS and Windows without any fancy patches.

If, when he first installed windows, the BIOS was not able to support dual core, then he may have to reinsatll XP to get the correct processor driver.

Nope- XP will autmatically install MS's generic version of either AMD or Intel proc drivers. I've *never* had to reinsall XP on a processor change (single-single, single-dual) What it will NOT do is adjust the HAL automatically. That you have to do yourself.

it was the msik8neo4 sli mobo.

swapped to an older msi k8neo4 none sli mobo

and it picked the x2 4600 up instanlty and works fine.
even oc,ed it to 2740mhz.

the msi k8neo4 sli (7100) sucks i have had two of them.

edit; the older mobo i mentioned is a (7125) version.

thanks for all the help.

update your bios, then enable the second core.

dork.

you seem to be the dork as you cant read.

i have already done that and so much more.

look at the post above yours.

you will find the answer there.
