Okay this is in BF3 on a 64 player map, seems to me like the cpu is holding back the card quite a bit.

There's no real upgrade for me on an AM3 chipset, and going FM with Steamroller around the corner wouldnt be wise before we get some more info on the chipset they intend to use.

The PSU is pretty solid, Thermaltake make some nice psu's. I've had three of them and never had issues, so far...

our numbers are pretty similar. i don't see the cpu pegged and you said the card was at almost 100%, right? i don't see the temp for your mosfets. make sure they, too, stay below 60C. as you can see, my Phenom maintained almost 60 min fps, which is great for a maxed out BF3 in 1080.

monitor your fps using fraps.

which is your reoslution???? there with that cpu at low res(lower than 1050p) you have 20 to 15% bottleneck
post #13 of 22
Looking at that board and and your overclock, there is defiantly a lot of throttling going on. I did not know the 1090t was 95w? That mobo is only really good for 95w CPU's (1 x 4 pin power connection) and is not a good board for overclocking due to its low CPU power phase count. For a 1090T to be oced to 3.9ghz you will need 6+2 or preferably 8+2 CPU power phase mobo, and VRM cooling, which you are missing with that board.

Resolution is 1680*1050. 22"

I did some graph comparisons to CPU:GPU and whenever the GPU load dropped to the floor, the CPU load increased. If I stand in particular spots like looking up at the sky or out to sea in BF3, or in the menu of D3, the card gets maxed out and I get well over 200 FPS (450 in d3, 280 in BF3 after increasing FPS cap) and the CPU was barely under load.

Without a doubt it's a CPU bottle neck, It's a long while to wait for steamroller, think it's worth while me upgrading to a Sabertooth and keeping the 1090T, which would likely get me a slightly higher overclock, and no throttling. Or just get the 8350 as well?

I'll be overclocking whichever I can to the max, and I think my current overclock at 4ghz could be bit higher if my board was better.

It's a while before we get Steamroller's, and if I were to get the 8350, would it bottleneck two 7970's in crossfire? (assuming around a 5ghz overclock)

What do you guys think I should do?

Okay so I ran OCCT and I found out that my CPU is actually throttling hardcore.


You guys were definitely right

It would drop down to 864 Mhz every few seconds

Perhaps you should try disabling two of your cores and see how it runs then?(and as a temp fix, until you get a new board?)

I dont really want to do anything that would give me less performance, idk what to do atm lol

You're already getting "less performance" so you may as well give it a shot to see if it'll force your CPU to stay at 4GHz constantly. If it does work then it means your board is indeed throttling the CPU for sure.

Yea its the board it seems. IMO the best option is to get a new board, you could find a good 2nd hand AM3/AM3+ board quite cheaply, 4GHz x6 should still be plenty in most games, especially in BF3 multi.

BTW I had a phenom II x6 1055T paired with a cheap Asus board and @ stock 2,8GHz it was fine, but as soon as I overclocked it to 3,3GHz it started throttling in BF3...

Having a 4 pin power connector for your mb cpu is what is throttling the cpu. I have seen this many times here at OCN. I'm actually pretty surprised your able to keep a 4.0 overclock on that 1090t. In most cases I have seen the voltage will fluctuate to much to keep it stable. Most people can't hold a 3.6-3.8 overclock stable with only a 4 pin power connector.
