    Anyone had experience overclocking the opteron on a dfi sli-dr expert?

    Having problems, surprise surprise

    it will only oc 90mhz on the mach 2 with gskill 4800 ram :(

    if i go any higher it stops after listing the devices during boot.

    i have tried more vcore, vdimm, highest timings, 2t, lowering ldt, more chipset voltage etc etc, but nothing will make it boot above 210 htt :(

    also the cab2e's are supposed to e an ok stepping
    got the chip of rosco and it said it was @ 2.8ghz on air or water (cant remeber) :(

    Probably the mobo holding it back.

    doubt it mate, this one of, if not the best at running high htt's and good overclocks.


  • Banned (with Prison Access) Posts: 21,634 ✭✭✭✭Richard Dower


    It is on paper, but every mobo is different and does appear your one isin't behaving nice and allowing all that high HTT and VCORE to kick in.

    Thus i suggest your particular mobo (not all DFI Expert) is holding you back, do the normal stuff...update bios, check settings etc.

    do the normal stuff...update bios, check settings etc.

    thats all done mate

    looking to see if anyone with an opty and this mobo has any advice and results


  • Subscribers Posts: 6,408 ✭✭✭conzy


    lower the multiplier to like 5 or 6 and see how high you can get the Htt and ram.........

    If you cant get a high htt its the mobo im afraid:(

    Try Oc the opteron in a different board.......

    Well if your chip OCd for someone else it's almost definitely your board...

    this is 3rd expert,
    brand new from rma from komplett


  • Subscribers Posts: 6,408 ✭✭✭conzy


    I dont know how you are so unlucky.....

    Lots of people had great sucess with the Expert.

    I bet Komplett got a box of experts, and they are all a bit dodgey, everytime you RMA, they give you one from the same batch................

    Try get your money back, and buy a new Expert from OcUk

    yeh maybe, il have to play around it and try everything, next is taking out battery all night to reset it

    also i noticed wen i booted this mobo up 1st time it had the time already set, which meens it had already been used, probably wanst brand new, it was probably someone elses rma or something :(


  • Subscribers Posts: 6,408 ✭✭✭conzy


    Its probably you're original one:D :D:D

    But taking the battery out for 5 minutes or a week wont make a difference, once it clears its cleared.

    clear the cmos jumper, take out the battery, have a cup of tea, put in the battery, replace the jumper and its cleared.

    Will it not boot at all now ????

    dfi guys tell u to leave the battery out for a few hours as it holds a charge

    yeh it boots fine, everything runs grand at stock speeds
    but wont boot if htt is over 210 (extra 90mhz oc)
    no matter what settings

    il try take out battery and swapping dimms into different sockets and taking out soundcard etc


  • Subscribers Posts: 6,408 ✭✭✭conzy


    do you have any other ram??

    try one stick on a divider, kepp it at ddr400 and oc the CPU.

    Try yellow slots, orange ones drive the ram harder........

    Good Luck;)

    yeh i have corsair 4400 spare

    il have to fiddle about with this, damn u dfi.. source of lost hours


  • Subscribers Posts: 6,408 ✭✭✭conzy


    ahhh, but source of happiness when everything goes well, like my 3700 at 2.8ghz at just about stock voltage;)

    What's the week number, e.g. CAB2E 0536? CAB2E are generally not among the best o/c'ers and to make matters worse, they seem to be one of the most varying steppings in general with regards result. You might just be unlucky and got one that doesn't clock at all

    I take it you did NOT see proof of stable results @2.8 (or even just Pifast completion) before you bought?

    true

    but the week number is 0548 epaw
    which all results i have seen online seem to be good - 2.7-2.9 on stock cooler


  • Registered Users Posts: 6,630 ✭✭✭gline


    ok pulling the battery lastnight allows me to boot @ 220htt
    but 230 is no go, the windows loading screen comes up faded and doesnt go from there

    on xtremesystems forum 1 of the guys reckons its cold bug

    il have to do a bit more testing etc


  • Registered Users Posts: 6,630 ✭✭✭gline


    fails memtest @ 230, passes @ 200
    hmm


  • Subscribers Posts: 6,408 ✭✭✭conzy


    Wait are you using phase???????

    If you are its definitely cold bug, nothing else could be wrong, maybe some more startup voltage.........

    Slap a stock HSF on it and you will get 2.8ghz, maybe

    Thats what i would have tried first...

    I can gurantee this chip will clock faster than 2.8ghz.. I've seen it clocked at that speed, saw another one from the same batch clock @ 2.96.


  • Banned (with Prison Access) Posts: 21,634 ✭✭✭✭Richard Dower


    It's luck of the draw when overclocking, one guy may have had it stable @ 2.8 in his rig...but every rig is different. You could have ten motherboards of the same brand/model and they will all act differently to overclocking.


  • Subscribers Posts: 6,408 ✭✭✭conzy


    Gline will you try with the stock HSF?

    I want to know how it goes..........

    i know it aint the chip, i will try it on another rig in a week r 2
    i have a 146 coming from komplett for my 3rd rig, so il swap them over and we'll see

    is there any issues with x850 xt's on dfis? could it be gfx?


  • Closed Accounts Posts: 2,279 ✭✭✭DemonOfTheFall


    Why not try with the stock cooler to eliminate cold bug from the equation ?


  • Registered Users Posts: 6,630 ✭✭✭gline

    that will be the last thing to try, its hard to get the mach 2 stuff off and remounted


  • Closed Accounts Posts: 2,279 ✭✭✭DemonOfTheFall


    Ah yes... suppose it would be pretty damn hard.


  • Registered Users Posts: 792 ✭✭✭Dman_15


    I'd guess cold bug.

    but try playing with Max. Async and Read Preamble

    8 4, 9 6, 9 5.5, 6 4 etc.

    These two settings are often the key with the opterons. I had major instability untill i found 9 6. I know i'm on a DR but the same setting is in the expert i think.

    Auto = bad for these two settings

    Just play about with them. There is no rule as to what works. You'll have to try them all.
    Async should be higher than read preamble, but thats the only rule. 8 6 wont post for me but 9 6 is sweet as a nut. It really is just time and guesswork
