Hi everyone,

I'm posting in systems because this has a more system related issue because I'm not sure what's going on!

I dont know if this has anything to do with wacky performance via issues with disabling functions in the bios or what...Just got a new Gigabyte 990fxa-ud3 rev.3 board and 8GB corsair vengeance pro series (9-9-9-24, 1.5V, 1600MHz)

I just overclocked my Phenom 965 on my new 990fxa-ud3 mobo and pulled out 4.0GHz at 1.5V and 2600NB at 1.3V. System stable prime95 and IBT for hours upon hours. I simply did Multi OC technique instead of FSB.

I just started up BF3 and playing at ultra settings on my also newish Gigabyte GTX 760 windforce factory OC and OC'd on top of that , totally stable been playing for weeks at 1170MHz core and mem at 7008 MHz. This setting gives the best results in Uningine Valley and overall gaming performance in BF3, crysis 3 and Metro LL.

I am currently in game in BF3, annoyed with my fps and its bringin me down man!

before I got the new mobo/ram I was playing on ultra in BF3 and feel like i was barely hitting below 40fps when my cpu was at 3.8Ghz and 2400 NB... now with my new board and ram i'm getting in the 30's more often.

G15 LCD displaying consistently above 90% CPU usage, about 40% RAM usage in game.

I don't know whats up!? could this be diminishing returns at 4GHz since the phenom is nearing the end of its life? its a C3 stepping and I have disabled all functions in BIOS such as Cool n quiet and C1E (as per other guides suggesting to do so)

what's goin on!? my old mobo / DDR2 seemed faster in BF3... lolz!!!!!!

any more info you guys need to help w/ this problem plz lemme know

many thanks

You wouldnt expect a mb change to make any performance difference

you would expect an overclocked cpu to hit thermal throttling and turn itself down when its too hot

The good news is you can drp a steamroller cpu in that board in a few months time and kick sand in the face of the intel fanboys and their haswell processors

I did a test here's what I found out whats up but dont know the cause. I ran Uningine Valley at extreme HD settings and here's what I saw:

- at 4 GHz - average fps in valley benchmark is about 30

- at 3.8 GHz - average fps in valley benchmark is 43.7

- at 3.8 GHz w/ NB at 2400 MHz - average fps in valley benchmark is 43.7

The 43.7 fps in valley is a whopping 1 fps higher than before with old mobo (ga-ma790x-ud4p) and RAM (4GB DDR2) at 3.8 GHz for the CPU (with same NB settings as before I upgraded). Is this kind of small gain typical for just a mobo and ram upgrade?

Questions

1) Regardless of NB speed, valley which is highly GPU dependent has no effect on gaming? This score is 1fps higher than on my old setup at 3.8 GHz with same NB tests done on my old rig.

2) why the H E DOUBLE HOCKEY STICKS is 4GHz 10 fps lower !? In terms of this benchmark, that directly implies that 4GHz performs 25% worse in the benchmark than it does at 3.8 GHz ? temps are fine though...mid 50's in prime95 and IBT....does this have to do with RAM or fsb ratio? crappy phenom performance at higher temps? WHATS GOIN ON ? :(

any help would be highly appreciated, and I will personally crown you a knight of the internet!

If it helps...I've had the card at about 4.2 Ghz for most of its life 24/7. it never overheated, was in the 40-55 range in games depending on how CPU bound the title was. It started blue screening a lot months ago and I knocked back the OC on my old MOBO/RAM combo and set it back to 3.8 which is how I have the data for previous mobo/ram fps in valley.

clearly my CPU is performance is WAY worse above 3.8GHz in games...is there anything I can do? whats goin on?

/facepalm for days lol

many thanks
