And while I'm here I'd like to prove to everbody that there is "not" in fact an AMD CPU bottleneck with two GTX480's in SLI, for example Battlefield 3 Ultra Spec on Caspian border I get on average 80~85 FPS both GPU maxing out at 95% and the CPU only shows at most 65~70% usage! Estimated that's enough room there to quite possibly add a third 480 in there and still not be bottlenecked by this cpu. thumb.gif

That sounds like a slight bottleneck. If it was truly GPU bottlenecked, the usage would be up at 99% a vast majority of the time.

Some boards can't unlock certain chips but that's true for all chipsets, not just 990x.

I'm just posting based off my own experiences and other available information I found whilst having this problem. I switched to my current board because of the availability to update to AM3+ compatibility if I ever needed to and so I could enjoy my 960T. Not trying to force my opinion or anything just trying to warn people of the problems I and many others have had with the 990FX chipset when it comes to unlocking processors. wink.gif

Do what you will but for now I'll just steer clear of the 990FX for awhile. redface.gif

I got curious as to how CPU-NB speed actually affects real world situations.

I ran the GTA 4 in-game benchmark 3 times at each OC to get an average FPS.

960T X4 CPU @ 3000 Mhz & CPU-NB @ 2000Mhz = 38.03/36.47/38.76 = 37.75 AVERAGE FPS
960T X4 CPU @ 3000 Mhz & CPU-NB @ 3000Mhz = 39.83/38.05/38.08 = 38.65 AVERAGE FPS

I got no difference in benchmark FPS between 1600 and 9-9-9-24 and 1667 8-9-8-20 on my RAM.

Soooo ... 2.4% performance increase for a 1Ghz CPU-NB OC. I guess NB and RAM OCs (in that order) are definitely the last things you need to consider when OCing.

Kinda weird. Last AMD rig I OCed was 939 with DDR and I remember being able to notice the difference in the responsiveness of Windows XP between DDR400 3-3-3-8 and DDR400 2-3-3-6 and now theres no difference between 1600Mhz CL9 and 1667Mhz and CL8.

My 960T unlocks on a 880 MB. Its currently in a HTPC duty @ 1.2v X3 3.4GHz running FAH 24/7 along with a Geforce 210.

Same thing with my 960T except Ive only had the 960T for a month now but in my brothers board which is a 990FX it wouldnt unlock anymore? Just sayin here that you are one of the few lucky ones that got one to unlock on a 990FX board. Glad you were successful but the chances he gets lucky like you are even more slim than getting a miracle 960T to run x6 @ 4.5Ghz 1.5v stable.

990FX is great...and it's perfectly fine with unlocking cores (provided your chip has good cores).

I hear you; I just think it's rash and unwise to blame an entire chipset for a pair of unfriendly mobos. There are so many thousands of factors to take into account. I see more "few lucky ones" on 990FX than "*** THIS WORKED ON MY 880" others - in either case it's all anecdotal; innocent until proven guilty imo. Unlocking is a mysterious an unpredictable thing in any case, and it's definitely not a smart idea to BASE YOUR ENTIRE CHIPSET off of it like that. IMO, get the 990FX if you have the choice. That's what I did, and I couldn't be happier. Except if I'd gotten a Fatal1ty. lol

And sorry for the double post, but SERIALLY, who's gonna start the 960T/1605T club?!?! <3 <3 <3 regardless of chipset, we all lurve this chip! It's a monsta!

Now run the same tests but add the overclocked memory to the 3000MHz NB speed.I bet it jumps to 3.5% improvement over the stock speeds.thumb.gif

RAM speed didn't seem to be relevant at all to GTA 4 for my rig. Granted the bottleneck in games is my GPU moreso than the CPU or RAM. There was only a .2-.3FPS difference between DDR3-1066 and DDR3-1667 regardless of the CPU-NB speed. redface.gif

That being said, my chip is about average as far as OCing, but it seems to like low voltages. Any one else undervolting? Kinda hard to gauge if my chip is abnormal since everyone seems to be only OCing biggrin.gif

480


960T @ X6
1.2v in BIOS = 1.168v after vdroop
200x15.5

Gonna let run for 24 hours but all seems well so far.

But my 960T is a 1600T not a 1605T guess I can't be in the club then. frown.gif

And I'm basing my mistrust of the 990FX on several factors of which I've already explained prior to this, The 990FX chipset is awesome in plenty of other ways I'm just saying why get a 990FX anyways if you plan to be using an unlockable Phenom II and with the 990FX you'll more than double your chances of not getting a successful unlock? It just doesn't make sense to me.
