As per the temps, AMD Overdrive reports socket temps from what I've seen, and not package/core temps. I have the 990FXA-UD3 rev1.2 and that's the case with mine. As far as it's been discussed, core temps and not socket temps are the ones to keep under 62C. And usually socket temps are 11-13C higher than core temps in HWmonitor or HWiNFO32.
What are your RAM settings with the FX and what are the temps you're seeing? I don't know if you've read this but CPU-NB on the FX chips are nothing like the ones on Phenom II, especially Thubans. They don't clock nearly as fast and even if you've said the PC is not overclocked, just make sure CPU-NB and the respective voltage are at stock values.

Well, I didnt clear CMOS. But I did update to the new bios which reset everything in the bios. But I did not use the jumper....

Using Core Temp, at stock everything, the FX-8350 had a low of 37 and a high of 49. Overclocked to 4.5ghz it was hitting 51 degrees.

Ram settings were either on AUTO which set the speed to 1600mhz and timing (that was off) or I manually set the speed to 8x multiplier for 1600mhz and set the timings manually to 9-9-9-24.

I took the chip to AMD's campus and had a lab tech test it in one their reference boards, but it had the RD890 and SB850 chipsets. It passed their tests just fine. They are going to look for my motherboard in the labs and try to test on the 990 +950 chipset.

Sorry Kyad, I don't like LLC either. But my experience is limited with as I have only used one board (Asrock 990fx extreme 3) that has it. I experienced wild temperature spikes when using LLC and no real gain in stability vs manually setting the voltage to compensate for Vdroop. It's my belief that a chip is going to need X voltage to be stable with or without LLC and if the board can supply that voltage steadily you are in business. I also believe that running higher volts with out a load really doesn't hurt much because there is no heat. Could be exercising my right to be wrong here but that's the way I see things.
To each his or her own, but I prefer to control the voltage rather than letting the board do it - just my 2cents.gif

Don't know what was going on with your ASRock, but LLC keeps voltage dead on as opposed to droop (or adds voltage when under load... but why do that? I mean really... C'n'Q does that, why do you want LLC to do so as well?). Nothing harmful about it.

Not saying you're wrong for not wanting it, saying calling it a bad thing is wrong. Voltage reqs will be the same either way after you account for vdroop under load, of course, voltage is voltage. I think Red posted something about how the non-steady voltage of non-LLC hurts the CPU or something, maybe, but Ph II's lived without it, so eh.

To keep it in perspective, as far as I can tell, your argument is "it's not needed", which is very different from his "it's a bad thing".

Also, I only singled you out for the 1.6v and the ~.075v vdroop 'cause your numbers were fresh in my head, I'd have picked someone else if I could remember theirs. tongue.gif

I did CK. It's called ripple.
is the small unwanted residual periodic variation of the direct current (dc) output of a power supply which has been derived from an alternating current (ac) source.

Ripple causes heat and more 'wear and tear' on everything electronic. I think he may be referring to an article that Anandtech did on ripple. The article was done in 2007 and motherboard components and tech has changed a great deal since then namely capacitors and MOSFETS, and LLC does not create voltage spikes from high load to low load as it did then.
This article from OC.net pretty much sums things up

You can pick on me CK, without LLC, my voltage drops a full .10.

I get pretty radical voltage drops as well if i don't use LLC at ultra. Much prefer a rock steady vcore to one that droops a hell of alot biggrin.gif

When software works on one system and the exact same software is run the exact same way on another system and fails, the fault isn't in the software.

This doesn't match my experience. I have high quality memory rated at 2400 MHz and I can't get my system working (stable) at any higher overclock if I set the Ram (underclocked) as 1600 or 1866.

I also can't get my memory working at 2400, but that's another story. My CPU/MB/Ram combination doesn't seem to work past ~2350.

If you have trouble making your memory work at faster speeds, you can try upping your CPU/NB volts, but some motherboards don't seem to be able to handle fastest speeds no matter what you do. That's one reason I went with a Formula-Z instead of a Formula -- it's supposed to be able to handle 2400. For me, the combination of my CPU and MB didn't quite get there, but they've come close.
