Need help unlocking i7 950 to a quad |(

T3kl0rd · Oct 10, 2010

My new i7 950 is showing as 1 core two threads in BIOS, CPU-Z, OCCT. I just changed motherboards for another ASRock X58 Extreme and it is doing the same thing! Is there a logical explanation for this or do I have a lemon? thanks all

Fourstaff · Oct 10, 2010

Wait, what? i7 950 should have 4 cores and 8 thread by default, or I haven't been following intel's lineup

eehhhhh sounds like a dead chip

did you try resetting the bios?

T3kl0rd · Oct 10, 2010

I upgraded the BIOS to the latest, 2.50 on the last mobo and it didn't change anything. I'll try it again but I'm not holding my breath. Is that what you mean (FIH) The Don?

Yukikaze · Oct 10, 2010

The only thing I've experienced that was similar was an old S939 motherboard which was not BIOS updated to recognize an Opteron 180 and showed it up as a single core, but if you've updated the BIOS you might have a bad chip.

(FIH) The Don · Oct 10, 2010

by resetting i mean either take out the battery, or load default settings

T3kl0rd · Oct 10, 2010

ASRock website states all BIOS versions for my mobo recognize the i7 950, so it's not like going AM2+ to AM3.

I'll load default settings again, already did that when I got Bad CMOS message on startup initially.

(FIH) The Don · Oct 10, 2010

i would return the chip to either the store you got it from or intel

T3kl0rd · Oct 10, 2010

Flashed BIOS to 2.50 and loaded default BIOS settings, no change in missing 3 cores. Was going to return the CPU ASAP but was hoping someone else had experienced this to save a trip.

(FIH) The Don · Oct 10, 2010

just a sec, can you find cpu options somewhere and manually set the core number?

i know you can do this in my bios, and i coul do it in many other boards

T3kl0rd · Oct 10, 2010

I was looking for that, I didn't see anything like that in the BIOS. Even if it was there, why wouldn't it be set to use all 4 cores by default?

(FIH) The Don · Oct 10, 2010

yeah idk either, i think the cpu is deadish

T3kl0rd · Oct 10, 2010

Actually, I did find something that lets me select cores but my choices are ALL, 1, or 2.

(FIH) The Don · Oct 10, 2010

try all

if that doesnt work then throw the cpu back at them

great advise, maybe it's windows fault, try a reformat?

T3kl0rd · Oct 10, 2010

I have always had it on the ALL setting but that doesn't produce the other 3 cores/6 threads that are AWOL.

T3kl0rd · Oct 10, 2010

Device Manager shows eight cores.

lisburnni · Oct 10, 2010

is your cpu heatsink too tight , ive heard of this before , also try turning HT off in bios - this happened on GB board i had once , it originally booted with HT on and cpuz etc showed 2 cores and 4 threads , once i turned it off it showed 4/4threads which was normal , and worked ok from then on in no matter if HT was on or off.

T3kl0rd · Oct 10, 2010

I turned off HT and now 2 physical cores run instead of 1 physical and 1 virtual (hyper threaded). I used this Windows 7 install with my old CPU which was a Phenom II X2 550 dual core. I installed the new mobo/CPU without reinstalling Windows 7 and reactivated by phone. You think Windows is configured to recognize 2 cores max somewhere? How do I access that without having to reinstall?

scaminatrix · Oct 10, 2010

CMIIW but when changing mobo, I've always thought you should reinstall os?

ditto reinstall OS everytime you change any major hardware. like mobo or CPU or VGA.

overclocking101 · Oct 10, 2010

wait a minut device manager shows 8 cores?? check your windows start up options m8. this happened to me. if you have it set to anything but all on your windows startup options this will happen

There is absolutely no need to reinstall the OS for a change/addition of any of the following:
1) GPU
2) CPU
3) HDD (Unless the OS was on it, duh)
4) ODD
5) PSU
6) RAM

I have also changed motherboards (between the same chipsets and between different chipsets) without any issues, as well, but this has more of a SNAFU chance.

yes??
i know your system will still work, but it will work even better after a reinstall.
i experienced it myself.
after changing my mobo and CPU to the current, i didnt reinstall, but later i reinstalled and was amazed at the true power of the Phenom II!!

It sure will, because most systems work better after a reinstall (unless they are brand new, then there will be no advantage at all). Otherwise, there is no change. There is also no reason why there would be one.
