  1. Small FFTs

     

    FFT stands for Fast Fourier Transform and is an algorithm to compute discrete Fourier transforms for a sequence of n complex numbers (groan, more math – I’m outta here). The Small FFT test loads neatly into your L2 cache so it tests primarily your CPU. Ram will generally only be affected whenever more data has to be fetched into the L2 cache. The small FFT test is good if you’re just looking to give your CPU a good burn in or test your cooling sub-system out. This test will heat up your CPU, so watch the temps.

     

    In-Place Large FFTs

     

    Due to the nature of in-place FFTs, they do a lot of moving data and swapping to and from memory during the computations. So this test gives your CPU a work out along with some of your RAM. It will also heat up your CPU quickly so watch your temps closely.

     

    Blend

     

    Blend is my favorite since it works out everything. Blend will use small and large in-place FFTs so everything (CPU and RAM) gets a nice work out. Unless you use something like memtest to check out your memory, I recommend the Blend setting. Blend, like the other test, does indeed give your system a work out and the temps rise rapidly. Not to be repetitive, but keep an eye on your temps lest the toasty aroma of a burned CPU begins to fill your nostrils.

  2. Nice one. thanks

    Also I have an Opty 9x multi, will there be enough FSB to push that cpu far enough,

    and I am thinking of the G.skill ram 2GB HZ to go with that, also "thinking" of 1900xt, any issues?

    many thanks

  4. !st choice

    Not that I like modular power supplies but is this suitable :

    Enermax 620W Liberty Modular Power Supply - ELT620AWT

    Dual 12v rails 2x22 Amp 12v combined 36 Amp.

    I read that dual 12v rails are a better design than quad rails ???

     

    600w Seasonic S12-600 , think I read of an issue with these PSU's though.

     

    700W FSP Epsilon FX700GLN

     

    660W Enermax EPS12V EG851AX-VH

     

    600W FSP FX600-GLN Epsilon

     

    thank you .


  5. I am Wanting to build a new system and would like some advice on components that will be compatible with each other.

    I already have a Coolermaster Stacker.

    and an Opteron 144 939 cpu.

     

    I am thinking of buying the DFI expert......good choice ?

     

    I am also thinking of buying G.Skill HZ 2gb kit.....Or maybe the mushkin red line...any opinions on any of them?

     

    Also I would like a suitable PSU with enough power to run a X1900XT......thinking of perhaps

    700W or the 600W FSP Epsilon..........600w Seasonic S12-600.........660W Enermax EPS12V EG851AX-VH....or the 600W Enermax Noisetaker.

    Opinions please.

     

    And heat sink and fan suitible for that board.

     

    Thanks in advance.


  6. I have read the sticky, not sure if i understand it though.

    It states that it does not matter weather you run the memory at 1.1 Or you use dividers as long as you get there.

    So why would people buy ddr 500 and try to get 1.1 when you may as well just get ddr 400 with better latency and use dividers.

     

    I am wanting to buy some memory and not sure which to buy.

    I have an opty 144 which as you know has a 9x multiplyer so i need to push the fsb quite far,

    was going to buy G.Skill 4000 2x1gb and run 1.1 as high as possible for gaming and the like, now not sure weather to buy ddr 400 with better timmings and use dividers.

    Just a thought, would ddr500 run better than ddr 400 both using dividers both at the same FSB but obviously divided differently?


  7. @mrtell

    don't bother with these sticks, i wish i hadn't. my new sticks still wont run in 3d intencive games but my G.Skil eat games up and there only 512x2 sticks.

     

    RMA time again. Im going to ebay these new ones when they arrive and get G.Skill or OCZ

    I see you have an expert

    I will take your advice and stay clear of them i think.

    Not sure what to buy instead though, wanting good 2 gb overclocking ram

    thank you


  8. Its been mentioned the Ballistix 2gb dont have an issue with the expert, or should i say they run well on the expert, is that always or just with a lucky few.

    I want to buy a motherboard and reading the recomendations its been said the expert is no better than the DR for overclocking and the DR has a more mature BIOS, Thing is, is it better to buy the expert just so i can use the ballistix or go for the DR and buy some different ram. Not bought anything yet except an opty 144.


  9. mrtell , to that post...

     

    Two weeks ago a female at crucial said they where aware of problems with the ballastix

    memory and was currently going through research to find out why, the phone call today

    was different they where unaware of any problems at all and the low stock was just

    rushing to buy the ram..

     

    Withholding info?

    Lieing?

    Retail Bs?

     

    who knows

    TheyTell me something / they tell you something different. Do they not realize we all talk togeather, Does one hand not know what the other hand is doing or are they trying to misslead us???

    I will post a copy of my E-mail from crucial "if i recieve one"


  10. e-mailed crucial in scotland to ask is there a problem with the batch or is there a problem with architecture with there being so many problems, reply was that they were unaware there was a problem with the ballistix 2 gb kit.

    I telephoned Crucial and spoke to somebody to ask the same question, she also said there was not a problem and told me because it was high performance ram it was difficult to set up and the people having problems just did not know what they were doing! She then suggested that with this ram being difficult to set up i should perhaps consider Crucials other range, I was not at all happy with that reply so I e-mailed the european general manager to complain, I pointed her to this link and pointed out that the people with the complaints certainly do know what they are doing, she apologized, said she would retrain the person at crucial in scotland and said an expert would be in touch with me. the "expert" telephoned me to say they had followed this link and had been in touch with Crucial in America who had also then been in touch with DFI to find out if it is only a problem with DFI boards, he said he would get back to me at ther end of the week to advice weather or not there was a problem with the DFI boards and I assume weather there was a problem with the ram.


  11. got myself an opty 144 1.8gh

    know basic overclocking but not much, lowered the LTD and raised the front side bus and now that opti 1.8 runs at 2.6 prime stable with no extra voltages anyware and just standard ram, temps = 49 when usuing prime and when idol = 28. Wait till i know my stuff with a better board and ram

    Opteron 144 939 great cpu


  12. Thank you for the advice, i will follow the link.

    According to Trebaruna there is no need to have any new posting, just search all of the time!Nice.

    DFI has a good rep has having the best user forum in the hardware world, Trebaruna does not help that rep!

    I am new to this forum, still finding my way around so all the help i can get is good.

    thank you


  13. WOW impressed with the responce

    after a bit of research it looks as if the SLI-DR Expert is the one to get. coupled with an opteron 144 should be good. need some new mem and psu (best for this board) ANY suggestions
