I just bought a DFI Lanparty Motherboard and ive OCed my Athlon 64 3800+ to 2.8 Ghz and when i play games after 10 mins i hear a high pitch noise coming from the CPU and then my FPS drop to 30-20 from around 100.

Any1 know what this is? Any help would be great cause i can notice the speed difference lol.

Thanks,

Kurt

If you're hearing noises and getting unstable performance from an OCd CPU, then chances are you are pushing it too hard. The best idea is to incrementally(0.1Ghz at a time) drop the speed on your CPU and see if you continue to get the same performance issues. If you reach a speed at which all of the problems stop, then that is the best you are going to get out of that CPU. Trial and error is often the best way to judge the OC ability of a CPU as every CPU and Mobo are different.

Have you had any luck isolating the issue?

Yeah it was CPU Throttling. Im trying to get a stable 2.8Ghz but no luck so far keeps freezing in windows. In the BIOS I changed the FSB to 232 and the Vcore to 1.56v and the RAM to DDR400 so its running around 262Mhz atm. What can I do to make it more stable. Yesterday I got it stable and playing CS:S for around 30 mins but then it frooze again.

try loosening up your memory timings...use everest home to benchmark the memory...you might be suprised to see that by doing that the read write speeds in increase...anyways its helpful to see whats going on when your changing the timings and it runs quickly...think seconds

[rumble291]

How would i be able to do that ive tryed changing the lactancys but i just get BSODs

[happyrock]

what have you got the timings set at...you can also set them to auto

2.5-3-3-7 and ive ran my CPU at 2.7Ghz stable and then memory is at 450Mhz.

[happyrock]

did you get everest and benchmark your memory...write down the results..

try 2.5 4 4 8 then run the benchmarks again...compare

The 2.5-3-3-7 gets only slighty higher Read and Write MB/s and low lactency than 2.5-4-4-8.

[happyrock]

set them to auto and benchmark again

[rumble291]

The lactancys lower at 48.8 and the read and write speeds are lower by about 40mb.

I have to leave on a trip in about a hr...i will be offline at least thru tomorrow nite...if you haven't got it figured out by then I will start helping try to figure it out...there are other people that may help while I'm gone..sorry we didn't get-er-done

[rumble291]

I think it might be the RAM cause its only DDR400 running at 450mhz stable at a 2700Mhz CPU Clock. Its alright now. Now i know of 2 things to invest in a pair of 2GB low lactancy RAM and a New mointor lol
