@M3TAI - It's good to know they covered his blown VRM. I didn't expect that to happen.

I'll see. For obvious reasons, I won't be getting another AM3+ board. But, when I do move to a new CPU, I'll have to consider what you said. I am thinking however, that they were so easy going about the RMA, because they already knew their boards VRM have issues.


@GroovyMotion - I haven't had issues with the voltage dropping with CnQ on, and HPC off.

Are you talking about your voltage dropping while at load, or when idle? At idle that's fine. If you're worried about that, simply put your computer into High Performance power settings thought windows. Set your min/max state to 100%. When you don't need it, set it back to balanced.

As for dropping at load, setting LLC to high fixed that for me. It does drop, but rarely, and only 0.010V at the most when running prime95.

I've been able to get what seems to be a stable OC with most of my power saving features on. No throttling, or Vdrop when under load, just when idle, or doing lite tasks, such as web browsing, youtube. I don't think you want your system running wide open when doing these things.

***Oh, and my 2nd monitor... Is getting spouse jacked. I'm going to give it to my ol'lady for the rig I'm building her. So, I'm back to square one on that. frown.gif

Nah I am not worried, was just wondering if it's normal but it's obviously normal smile.gif
0.010v is very little, I have a lot more than that even with mild OC! But I will do some comparisons with the LLC and the green stuff

That sux about your second monitor! frown.gif

Ok I did some more testing and raising the multi alone doesn't work past 4.2ghz! Tried +0.1v, +0.150v and +0.250v and it would not post. So,
I went back to the 'ol trick of setting the FSB much higher and lower the multiplier and right now @ 4.365Ghz it is pretty darn stable and with vcore at between 1.392 and 1.404v! smile.gif
I tried running @ 4.5 with same stable vcore but the cpu temp was 7C higher so there is no benefit for 135mhz!

Yea, she didn't really jack it, but, I got over my temporary bout of mental retardation, and realized I'd lose it sooner or later anyway. It doesn't take a psychic to realize that when it comes time to get a monitor for the system I'm making her, where that monitor's going to come from if I have 2 or 3 of them sitting in here. biggrin.gif

Are you messing with anything else? The main time I've had my system not post, was when messing with ram speeds, or, things that affect the ram speed.

I'm wondering if you're adjusting the BCLK clock, instead of multiplier. Leave teh BCLK clock at 200. If you adjust the BCLK clock, that will also increase other things, such as your ram. That could be the reason it isn't posting.

When I say multiplier, I mean the "CPU Clock Ratio". That and voltage should do it. Set your ram to XMP profile for now, or, leave it at base while testing for stability.

7C just from a 100-150 MHz clock increase? Don't think that's been my experience. Only get a temp increase like that from more voltage usually.

No, like I said, I was just raising the multiplier...it refuses to post beyond 22x. I had my RAM to XMP profile, this is the only thing I could see but it was still very close to default speed of 1600
So far I am very satisfied with the settings I have of 236Mhz FSB (BCLK) withg a multiplier of 18.5, NB@1800 and HT@2200 and vcore +0.150 it's extremely stable and temps are all great.

@M3TAI, I ran prime 95 for 10min on each settings and at 4.3 the cpu temp was 7C hotter...what can I say!

I don't know man.

You should try to run prime95 for more than 10 min. I like at least 2 hour, but, 4 preferred. It's a good idea to stress test, at least as long as you would stress you system in normal usage. My current OC, I only did 2 hours, but, haven't had any issues. I'll most likely come back later and do 4. Some like 24 hours, but, I find that excessive. I have had tests fail 5 or 6 hours into a stress test though. Still a good 2 - 4 hours should be enough to call it stable, assuming you don't end up with issues.

I just can't help but wonder why your system won't post off of a Multiplier / voltage oc past 4.2. That chip/mobo should be able to handle that without issue. At least I'd think.

Someone with more experience have any idea about that?

Yes the boards do need some actual revision on the VRM side of things (Gigabyte where is your digital stuff to compete with Asus?) but if you take proper precautions it's fine. They're not going to design a whole new board for a dead end socket like AM3+, it would be a waste of time and money.

Even though Asus has some very nice boards I'll be staying away from them due to all the RMA horror stories (such as this is RMA # 8 my board still doesn't work right, etc). After seeing how Gigabyte handled my friend's RMA of a 970A-UD3 with blown VRM, I'll be staying with Gigabyte. They gave him no hassle Advanced RMA.

Quick and easy. He called them up said VRM is blown, do you guys cover that? Yes. Do you do Advanced RMA? Yes. We will send you a form to send back to us, give your shipping and billing address. Not to mention that call was at like 4:58 PM (they close at 5 PM). He got the new board yesterday, now he's just finishing up the custom loop tonight and will boot it up after leak testing.

Boo ! SO no GB, no Asus, whats left of cheap for decent overclocking ?? asus, msi mmh ..I've also read somewhere to avoid the MSI just because their previous board had similar troubles.. leaves with little choice.. this is the local shop I go to usually : http://www.prodimex.ch/pGroupe.aspx?FAM=COMPOSANTS&ONG=CARTES+MERES&GRP=AMD+SOCKET+AM3 .. not so much choice and according to : http://www.overclock.net/t/946407/amd-motherboards-vrm-info-database this page those 2 asrock only have 4+1 phase count.. I guess my best bet is : MSI 990FXA-GD65 at the moment.. gonna see if there is a thread about it.. or perhaps some of you know already if it's worth investing.

By the way I saw the Asrock extreme 9 looks awesome, but 200 bucks, and I'm certainly not gonna invest so much for a 160 (current swiss price of this cpu) bucksCPU.. altought I would if the socket wasn't "dead" gee.., and the more I invest the closer I get to a possible haswell LOL, since I'm gonna do mainly gaming with it.. that's where I would go if I had bit more extra cash.

I made a Google Spreadsheet with my LLC findings. Hopefully I'm able to figure out how to embed it in this post for all to see.

This is on 990FXA-UD3 Rev.1.1 FX-8350 4837.5 MHz 1.475 V set in BIOS. Every LLC except Auto. Ran 10 runs of IBT AVX Standard. Ambient was 70F for every test except Medium LLC which was 69F. All case/radiator fans were run at 100% for every test.

I've always used Medium LLC, seems it gives a little more heat but most stability? I ran Medium LLC test twice both times the GFlops were in the 89-90's and the temps were the same.
