Please help, having problem with overclocking sandy bridge and low gflop

post #1 of 16
Thread Starter 
I just got my sb up and running today and i was wondering if 54.9 gflop was normal for a 4.8Ghz overclock? That's what i am getting, what am i doing wrong?




btw the snippet was taken after ibt was done... multi was at 48, bus speed at around 99-100

Try running on Max ram instead of standard. And just to confirm it was *not* being throttled to 1596 mhz during the test as cpu-z shows.

Here it is with max, after overclocking it to 5ghz gflop went down



Firstly: this chip seems to only be stable with a 51 multi and 100 bus speed at 1.51v vcore with llc on. IS THAT SAFE for 24/7?

My temps are pretty good at my highest core reaching a peak of 64C

Secondly why is the gflop still low?? ANYONE HELP?

it got lower

+ rep to anyone that helps

Usually when speeds increase and performance decreases, its not stable.

You need to install Windows 7 service pack 1 and get a avx version of intel burn test.

Download the latest linpack files from intel and drop them into your intel burn test folder.

http://software.intel.com/en-us/arti...pack-download/

Without service pack 1 you cant use avx instruction set which uses 256 bit registers instead of normal 128 bit. My score went up by 80 percent or more with avx turned on.

You should be getting at least 105-110 at that speed. Linx test also benefit alot from memory speed and lesser extent your memory timings.


I get 120 glops with 2500k at 4.5 and 1866 memory.

I get about 122.5 at 4.6.

Turn off hyper threading, you'll get better results that way.

Also. 1.51vCore is incredibly high.

My 2500k running Linpack avx draws 1.512 , fully 100 percent stable at 4.8, its not that high as long as you have amazing cooling and/or only run it that high for a couple benches. I decrease it 1 notch and its unstable.

I suspect most people that post amazing low voltage and high speeds arent truly stable. I find most stress test do poor job of quickly crashing unstable clocks, and games actually work better. Asssassins Creed Brotherhood will crash your sandy bridge in less than 1 hour where prime 95 took 8 hours.

lol, i have pretty good cooling, but i was wondering if i could keep this for 24/7

it just seems like i would have wasted money on my water cooling if i am not utilizing it.

no?
