DFI Lanparty NF4 UT Ultra
Mushkin Redline Xtreme Performance 2x512mb
AMD Athlon 64 Venice 3200+

NOT STABLE!!!!!!!!!!!!

With help from agw_01, I managed to get my new build to run at the above speed with the RAM at 250MHz at 3.2v with the timings 2, 3, 2, 5.

Will update this post with more details later...

Having to lower the cpu to 2.6ghz as it wont run prime at all, wierd.

edit... Been running Prime for 40 minutes at 2.53GHz, 1.5v. 281x9 FSB with the RAM at 253MHz.

Mushkin red extreme performance 2x512mb.

Dont really want to as it is running standard cooling, and even when we tried it at 1.55v we could not get it running at 2.62ghz. It ran prime for 2 1/2 hours without error at 2.53ghz so i have lowered the vdimm to 3.4v and am currently re runnig prime as i want to lower my vdimm.

whats the stepping?

To tell yopu the tuth i didnt even look before i installed it. Is there any way of finding out now?

Yeah bit scary want to keep cpu vots as low as possible.

Cheeky, it was not really stable at that point so left the pc to do what it wanted, had it stable in prime 95 for nearly 3 hours will need to shut it down soon its stoping me from closing my bedroom door.

I am happy with my overclock will post screenies soon and may enter my 2.75ghz (non stable) in the sticky at the top.

Did a 1m super pi in 33secs havent got that screenie at the moment.

Your TRC for memory should be 7 (RAS PRECHARGE + TRAS = TRC)

What would make it 14?

Probably just bios. From what i have read the above calculation i said is what a lot of tech sites say to do for TRC.

This site in particular is my favourite. Adrian's Rojak Pot - Bios optimising guide

Ok cheers will mess about with it tomorrow see if i can get it to 7.

Ok managed to get it to trc 7, runs stable still.

Idle temps are 30> and full load it hovers between 48-51, these seem ok?

temps seem ok for stock cooling but you might want to consider getting a better cpu cooler at some point.. also are you using any case fans? sometimes just having a decent airflow thorugh the case is better than having a better cpu cooler so you might want to consider that

Yeah i have 3 case fans at the moment and one on the memory will do a cable tidying up session and hopefully that will improve airflow.

Would this help temps?

Akasa 60mm to 80mm Fan Adaptor , and then buying a 80mm fan?

Possibly yes if you bought a decent 80mm fan that had a good air flow rating, but tidying up your cables definately would help the airflow.... also try and set your fans up so that they maintain a steady flow throught the case rather than just pushing hot air around the case

I will tidy up the cables when i put my other hd in, the fans at them moment i have 4

1x on the font sucking in air
2x on the rear blowing out air
1x suspended over the memory using cable ties to keep it cool.

So i will look at my temps after cable tidying, and if needs bew add anither silent 60mm fan somewhere or buy a 80mm fan and adapter to keep my cpu temp around 40-45 load. The pc has been on for 3 hours half an hour prime, installing new software running 3d mark 03 twice and 3d mark 05, and my current cpu temp is 27.

Does that seems ok?
