Anyone got a bum CPU before?

I just bought a AMD Phenom II X3 715 (Heka) for my Moms computer. Put it in and it starts up fine, but isnt stable at all. I finally started Prime95 on a torture test and Thread #1 quickly errors out. There is no option to disable cores or I would have done that before I had to leave across the state. Its pretty much unusable since as soon as it throws something to run on that core it BSODs.
 
I did, Its set to SPD. 5-5-5-15 2T DDR2-1066 at 2.4V. I remember I had to set that manually because it wanted to set timings tighter than SPD.
Still, its only the one core that fails. Never #0 or #2. If it was memory it would seem to me it would be random across all cores.
 
This CPU uses less power than the old one. Its 95W TDP, the old Windsor was 125W since it was a 6400+ Black..
Regardless, its a 650W PS.

Shuddap. It was already a AM2+ platform, I wasnt going to switch it out for a 1156 board with DDR3 and an i5.

Reseat the CPU. And, make sure bios is up to date and capable of supporting your new processor.

Why not? It would be faster and.... reliable

LOL!!!

Sorry, I gotta tease

did you reinstall windows?

I upgraded a amd single core 3800+ to a dual core (that was supported) and windows flaked out after "installing drivers for new hardware" and kept bluescreening randomly

till I reinstalled windows.

also is that an oc'ed ram setting.. seems to be high voltage and pretty tight timings

maybe set it to auto?

try the cpu in another system?

try it with 1 memory chip on auto settings.

is the motherboard bios updated? and that processor is supported?

you dont list enough information about the system to be more specific in answers.

No, I didnt reinstall Windows. Its only the one core that fails a hardware stress test. Core #1 or #2 depending on weather you count from 0 or 1. The other two run fine. Im sure if I had the capability to disable cores I could have got it to limp through the weekend as I am about 400miles away from the machine at the moment.
I didnt have time to run a memory test, but those are the recommended timing and voltage settings. Setting it to "Auto" causes the BIOS to call for even tighter timings and it wont even boot. I also tried giving the CPU a slight voltage bump, +.025V, to see if that would stabilize it. Noop.
I dont have another compatible system. I have another AM2 system but its not AM3 ready.
Im going to run through hardware tests after I get home Sunday night to find the source of the issue. I will use a Ultimate Boot CD to eliminate Windows variables.

AMD Phenom II X3 715 2.8GHz (Heka)
Gigabyte GA-MA770-UD3, Rev 2.0, FJ BIOS
4x 1GB Geil Black Dragon 5-5-5-15DDR21066
Diamond HD3870 512MB
Antec EarthWatts EA650D 650W (Delta sourced)
Western Digital Caviar Black 750GB
Windows 7 Home Premium 64bit

It was bum memory. I just found it odd that only the one core would fail prime95.
Booted UBCD and ran Memtest86+ and got thousands of errors in about 10 seconds.
Went into bios and loosened the timings to 6-6-6-20. No Dice. 7-7-7-24 Noop. It just WILL. NOT. DO. DDR2-1066. Which is lame because that is what I bought.
Backed off to DDR2-800 and its perfectly happy at 4-4-4-12. Which is interesting because even if I had gotten it to work 7-7-7-24 @ 1066 it probably would have more bandwidth running 4-4-4-12 @ 800.

Have you honestly ever had problems with AMD?
I've never been dissatisfied with an AMD system I've ever had, both in performance and stability. My previous Opteron system was as solid as they come, never required any attention at all, in 4 years.
That being said, my i7 clearly rocks.

Try having a few hundred, or a few thousand... You'll have problems with everything at least once. You'll also notice that AMD stuff isn't made as well as Intel, just by failure rates.

Is this RAM new or was it a carry over from the other build?

Yeah, alright.

Yes. I've worked on thousands of computers. I've experienced a distinctly higher number of issues and failures with AMD-based systems. Now, of course not all of them were CPU-related and so not really AMD's fault per se; simply the nature of using inexpensive CPU's on sub-par chipsets like those produced by SiS, ALI and VIA.

Intel makes chipsets. Superior chipsets. If Intel made chipsets for AMD CPU's, AMD would have a much higher overall reliability rating.

Instead, you end up with chipsets manufactured by companies that make graphics cards on the high-end, and companies that simply make garbage on the low-end. Neither of which and anything in between that can come close to the stability and reliability of an Intel offering.

I'm not saying every AMD offering is bad. That every system that is AMD is going to be an unstable piece of garbage. Because that obviously isn't true. I've seen MANY that work very well and are very reliable.

HOWEVER

My ex business partner was an AMD nutter. I was the "Intel Guy". He now runs Intel. Because after the umpteen bazillion computers that we serviced and built, it became quite clear that overall, the Intel systems were just "better". They weren't always faster. And during the P4 days, they weren't often faster. But they gave better reliability overall, broader compatibility, fewer quirks and were better supported under OS's that weren't Windows. They also had lower failure rates. AND you didn't have to deal with the hassles associated with chipsets manufactured by companies who just didn't do it like Intel did, and still does.

Comparing Intel to AMD is like comparing Mercedes Benz to KIA. They cater to very different segments. And while there is definitely some overlap in areas, it doesn't change the overall dynamic.

Yeah, alright.


He's right Nick. Want me to tell you how many AMD systems we've pulled from Hospitals? It is a number that hovers right around the zero mark.

When the budget is decent, the purchased product is Intel-based, no matter who the vendor is. Be it HP, Lenovo/IBM or DELL.

I don't go into a Hospital and see D-Link switches and routers either. But then D-Link isn't in the same class as Cisco and Juniper.

See where I'm going with this?
