Over clocking making my performance go down?

So I have a Phenom 965 I am using 3D Mark 11 as my main test to see how thing effect my system. I can OC with just changing the multiplier up to 3.7ghz. At that point I get my highest 3DMark scores. From 3.8-3.9 my scores go down each step I played with the voltage and it doesnt help. At 4.0 and 1.452v My score goes up a bit again but still lower than 3.7. I dont want to go past there because I still have the stock AMD cooler with 1 side fan right on top of it as well.

So does this mean the best performance im going to get is at 3.7 even though I can get it stable at 4.0 to where I can game for an hour and have it pass 3DMark and Prime 95. I have tryed different RAM set ups and the performance diff is almost unnoticible OCing my ram makes my scores go down if anything.


Thanks for any help or insite you can give :cry:

Hi.

HT Link won't give you any performance increase above 2000MHz, while CPU frequency and NB frequency does. Try to keep the HT the most possible near to 2000MHz, rise your CPU multiplier as much as you can and the NB frequency around 2600MHz-2800MHZ if you can, then you will see a difference.

Cool ill give that a shot might take me a few hours to find it. Biostar has a bios that at least to my noob self seems sort of hard to find things in :)

So just in case things are labeled all crazy and they prob will be. What do you thing the normal NB setting will be. Also will upping that make the board get hotter. I dont know how hot is to hot but it hovers arount 45-50 degrees wile gaming.
 
Yeah, all things in BIOS are marked "NB is NB", "HT is HT" you don't have way to lose the mind there.

For Thuban cores, the NB can go at 3000MHz but for Deneb cores (like your 965) the NB goes at 2600MHZ, some lucky guys can hit the 2800MHz.

45-50ºC are acceptable temps for NB.

So is 55c in the danger zone ? Because thats where it is with no OC stock lol. Not all the time but If i track min max avg I will see a max of 55c wile gaming.

Also when I hit a stable 4.0ghz at 1.452v Wile gaming the CPU temp doesnt go over 50c but prime 95 it will go way up I watched it go to 63c and stopped the test it may have went further. Should I be worried or is it ok being it wont go over 50c with normal usage (heavy gaming)

Average board temp is 47-50c.

My set up is the stock AMD CPU cooler ( looks good to me has some nice copper heat pipes lol) the stock CPU fan and one 75CFM 120mm side fan blowing right on the CPU and NB. So it comes down from highs real fast.

Well I have 1 4gb stick 1333 cas 9 and one 2gb 1333 cas 7 lol. So I prob am. Tried using just the 4gb stick and performance went down. And down even more when I tried to mess with the clock or cas settings.

Yeah Just dropped $1200 to set this up so as soon as I recover from that ill get another 4gb stick lol. The 2gb stick was from a prebuilt I had lol

So I just bumper my NB to 2400mhz seemed to help a bit at 2600mhz a start looping the win 7 boot screen lol. So would I be assuming correctly I would fix that by raising NB voltage? If so what is a safe level I tried to bump it up one level but that still caused a boot loop.

so at 2600 I bumped the voltage up 2 settings and windows would boot. But then the benchmark would not even start and some other programs where acting up does that mean I still need more or have I reached a wall at 4.0ghz CPU 2400 NB ? My cpu voltage in the BIOS is set to something like 1.465 but cpu z and the bios boot screen both state 1.452 so is that common?

Stock voltage is 1.100v after 2 bumps it will boot I think the voltage is 1.250v ish lol. and with my CPU OC and 2400 NB at stock voltage the board idles at 51c and hits 56-58c after gaming.

That was them.. lol CPU V-CORE is 1.452 NB is at 1.100v wile its at 2400mhz and 1.250 or so wile I have it at 2600mhz and at that point it will boot but I still have issues with some programs acting up. Do you think I should turn it up a bit more?
 


Too low I think, try with 1.275V or 1.3V on CPU-NB

My system may have just hit a wall. I can get the NB stable at 2600mhz with 1.2v and the CPU stable at 4.1ghz at 1.452v but now Im back to where I was the scores from 2400 go down at 2600 lol. Seems the best combo is 4.1 and 2400. 3DMark 11 gives me a physics score of about 4700-4800 give or take. But its way better than before I raised the NB it was at 4300 then :) I think when I get a second 4gb stick to match the one I have Ill try messin with the cas or ram speed to see if I can squeeze some more out lol Thanks for the NB info I asked a bunch of people and nobody even mentioned the NB before :)
