[18th Anniversary] Asus Black Pearl - P5k-Premium Testing Report

[sesdave]

Hi there, i used the settings you gave me with the tighter timings, running at 450x8 as well. looks good, but i pumped up the Vcore to 1.485 in bios and it shows 1.448 actual under load i believe. but its still not Prime large fft stable, it runs for about 5 minutes and then autoreboots. what could be the problem, any suggestions?

run looser timmings of 5,5,5,15 with auto subtimings until you can get prime stable.Whats your q6600 vid and batch - wouldnt have thought it would need any more than 1.45 in BIOS. What is your current setup - what cooling /psu ect. what temps are you getting on load? Have you enabled damper and disabled the speed throttling settings as per list. If still not stable try giving it CPU/NB ref volt of .61v to start then .63v and 67v if not stable.

I've had none of the problems that some folks have, I had Maxtors and Seagates from the start tho...

I do have one wierd thing going on with this board. If I take out the video card, the motherboard will not see the card until I turn the monitor off and back on. Took a little while to figure out. Other than that I love this board, but I think the DFI I had in the AMD days was a better built board.

Here's the overclock page if you want to look.

Erm, i can't remember the batch no, as i don't have the boxes with me, probably will go look for the Intel id proggy later, but it's VID is 1.2500. never thought that VID would affect a chip's ocability that much - noob me lol. anyway, my PSU is a SS OP 750W, liquid cooled by an apogee GTX, the idling temps at 3.6 at the stated Vcore is around 39-44C, kinda high lol... i followed your settings, damper is enabled, is the vdroop that high? i'll try out the ref volt settings now. thanks will report back soon.

CPUs with lower vid range tend to overclock better. I would check the seating of the HS. what temps did it reach on prime before it bombed.I am idle 36c and prime 62c with an ultima-90 . I only have a .025v difference between BIOS and reported on my MB. I also have a higher vid 1.2625v on my cpu which run 3.6 okay on vcore 1.425 - 1.4 reported with the posted settings. Still they are all different otherwise it would be too easy. Still is compared to the days of opterons and DFI mB's-lol!

well, i tried the Refs you suggested after loosening timings to default, and lowered the Vcore to bios 1.45 (actual 1.418) thats some droop there, is that normal? anyway, its largefft stable for 3 mins then reboots lol, even faster. weird... i'm getting 66-69 on load, probably due to my GC which is coupled in 1 loop.

EDIT : i see. lol so i guess its to each its own in this case? anyway, i pumped up the core to 1.5 bios, its 1.472 actual, so far its done 6 tests in Prime large FFTs, temps stabilizing at 62-71 lol... thats a crazy range diff.

anyway, how many programs out there actually stress your CPU the way PRIME does with large FFTs?

on a side note, what do the ref options actually do? Thanks

Pity - thought it would do it on lower vcore - still whatever it takes - lol! They are all different - not that much of a vdroop .028v. Heres a link to another thread to explain ref volts to save me the typing http://www.xtremesystems.org/forums/...152603&page=60.
read my post and the one from RLM. You could try the setting he suggests for fun-lol!
Would have thought you would get better temps with water - I take it you are using Prime 95 v25.5 . Do a razor check on IHS and HS and lap whatever isnt flat. A lot of q6600 are concave. I use MX-2 paste - doesnt need to cure like AS5 and is just as good.
