Official Phenom II x2 500 Club! - Page 192

post #1911 of 4289
Kinda thinking about tackling my oc problem. I had it on the settings that I'm listed as having on the first page of this thread. For some reason, while playing games I would get a BSOD with it saying something about my video card. At first I thought it was the video card oc or drivers, but nothing worked until I removed the CPU overclock. Now, without that overclock, my computer has been running fine for weeks. Any idea what might have caused the video card driver to crash (according to the BSOD) with a CPU overclock?

You need to run a multi-threaded benchmark that can make use of all four cores like CineBench 10, you will definitely see a difference with 2 and 4 cores in that benchmark.

As far as reading CPU Temp I use SpeedFan so I can display the temp in the system tray, there are others I've tried that gave same result.

Brutuz, wow then I am not sure. Your particular issue is the first I have heard of. Locking up after a few hours in memtest86 isn't normal. If there are errors detected usually it'll display them in red I believe. However I've experienced a few lockups in memtest when my memory wasn't stable but that happened within seconds.

PaperKuts, how long did you run Prime 95? Try giving the cpu a bump in voltage. It seems pretty low where it's at right now (1.248volts) especially for a quad-core. Just to clarify are you running DDR2-800 memory?

Kurt1288, an unstable overclock can display all kinds of errors especially while playing a game. Did you make sure to perform stability testing after making changes in your bios? Go ahead and make the appropriate changes again in your bios and post up some cpu-z screen shots. Hopefully we can point you in the right direction.

Good luck

Sorry for the double post. In regards to temperature readings, we posted a few pages back about the differences. The core temps for the dual-core were a few C lower than the "cpu temp" reading. I'm assuming once the other cores are unlocked the TDP goes up which also probably makes the core temps go up so using the "cpu temp" sensor to gauge is probably the right thing to do. The core temps are probably right below it.

I've found that for the 550, a CPU-NB of greater than 2.6 is very unstable, even though I have seen online that 2.8 is recommended. Also 1.3 v seems stable for me. YMMV.

Also, I always downclock like .2 from my stable desktop OC when I game. I figure why push it and BSOD right at the good part? What works fine on desktop can be problematic when gaming, in my experience anyway.

Mitchellvii, true 2600Mhz is pretty high. At that speed quite a bit of CPU-NB voltage is required. If you have a "golden chip" then you may have better luck at higher speeds but very rarely have I seen it. HondaGuy is one of the fortunate to have such a processor. I think he's hovering around 2700Mhz. A high NB Frequency with tighter sub-timings seems to be very rewarding from what I hear.

Thanks for the heads up on the various cpu temp programs. Seems none of them even recognize the existence of my cpu . It's just not listed. No worries. Unless I get crashy won't concern myself.

Hey, BTW, I have a perfectly good 6000+ I need to get rid of. Any ideas on the best place to do that?
post #1919 of 4289
Well I'm at 2600 on my CPU-NB at 1.3 v and it seems just fine. Tried some higher volts and didn't notice benches improving.

I do have a question though. I have NO IDEA what to set my HTT speed at or the voltage on that. Right now I have it at 2.2 with 1.2 volts. Have no idea if that is a good or bad thing. Any input on that would be greatly apprecaited.

P.S., One thing I have noticed. When I had only 2 cores, I was getting A LOT of HD thrashing - now with 4 cores none at all, which is welcome.

Mitchellvii, for the B50 (unlocked 550BE) it's completely normal for the temperatures not to sure up so I wouldn't worry about it. The "cpu temp" does show up. I'm thinking the core temps are about 2-4C less.

In regards to your 6000+, I'd recommend checking out the For Sale section but unfortunately you do not have 35 reps to post in there. My only other suggestion would be Ebay

Good luck
