woaw ! terrific GG there, can it boot (just boot) at 500 ? and or bench via setfsb with such an fsb ?

I think is a problem of chipset X48:yepp:Quote:

Hey you guys having that mobo, what was the bios at the VERY first boot? Mine is 0115. On asus support I only found 0201. What about you out there ??
:D Here too - 0115 seems to be stock delivery version, but not to find on the ASUS homepage...............:rolleyes:Quote:

@OverClocker_gr: If I do save it to a floppy or so before you get it, I 'll upload the .rom file. but i doubt it lasts soo long before you find one
If you can :)
I cant find it on the net :(
For me the 0115 is the best bios for FSB
On nb i have the fusion block from the maximus formula.

no matter the fsb you set, just cpu frequency 3600Mhz, easier to compare. You could maybe do a 4000Mhz eitherQuote:

thx a lot man! atm I boot at 550 fsb and spi4m passes allright :) soo different from GA-X38T-DQ6... amazing in deed
I search for my reference... beback soon ;)
here you go http://pix.nofrag.com/5/e/2/2b25a664...032204bc8.html
some parameters differ from you to me, but what I got is quiet similar to your score.
indeed its quite similar.
But with 1m its hard to do a comparison ;)
yes and for exemple of complication: how is your system optimized for that particular bench? mine was a bit tweaked, not much.Quote:

When i was trying to reach max fsb the mems were @ ~850-880
@ 1-1 maybe i ll go higher.

someone ask to the compatibility with the ocz gold 7-7-7, i have one of those and the max achieved was 1340mhz at 8-7-7-20 and more than that is no go wont boot :rolleyes:
with the gskill HZ is a complety different story and iīm very glad with the performence\price of them.

Yep jpcastro, I asked for that incompatibility issue and with the initial bios 0115(which i will keep for some time again), I don't meet any issue atm, Thank you to answer to that ;)Quote:

check your inbox :up:
i use VISTA 32bits for daily use and another disk with XP 32bits for benches :)

Very stable 1T & tRFC 60 (!!!) - only 0.02 Vdimm more than the blue Cellshocks, but almost half the price..........;)
BTW - if You have the feeling somthing is a bit unstable or You have probs during boot -----------> lower the Vpll.
With 1.54 I had reboots sometimes, with 1.52 it's perfect stable.

Keep pushing man
Look.
I have water on vnb so its *cool* the 1.75v.
If you are on stock air its too much the 1.75.
Maybe with lower vnb you could go higher cause of temps ;)
And at 600mhz i m with single channel.With dual channel i stuck at 597 :p
Did someone found the vcore and vdimm measure points on this card ?
the best vdimm measure point is on the dimm socket ;)Quote:

uau thanks for the screens camouflage, i´m gonna test the HZ again to see if i also can have 1T stable.
another thing did you test a Spi32 for example? i had to rise de vdim to have stablility but also made DDR2000 with 1,94v 2T

Man, I wonder the bios you had while doing that awsome fsb? tell me it is not the original so I can flash my mobo too :DQuote:

from a little test of 0401,its better for high ram speed.
With 0115 i m not able to use the 1/2 divider.
With 0401 its ok, BUT.. 480 and 1/2(rams @ 960) i am getting errors on memtest86+.
500 and 1/2(rams @ 1000) its error free :/ doh
i ll test the 0201 soon :)
ok, that's a good thing, accepting to loose high fsb then :/
thx
I received Corsair XMS31600 4GB. The ram doesn't like high voltage (up 1,96-1,98v) and very high frequency but works 1800 C7 1T :D

Man this is for P5E3 Premium.
Here we talking about P5E64 WS Evolution
should I give it a try while playing & benching on 3870X2 ? cuz I hardly enough left the original bios, so, .. :D
:confused::confused::confused:I have a strange issue - with BIOS 0401 (didn't test anyone else so far) I can only boot 1:1 divider (i.e. 8x563) or 1:2 divider ( i.e. 9x500) but all other:( dividers don't work for me....:( - it doesn't even boot....:mad:
So I wonder why I can't run higher RAM speed @ hi FSB.............:confused:
Anyone else with the problem? Is it a bug of the 0401? How about 0115 ???
Thanks !
:welcome:
Sav, please please post detailed settings and more extensive stability testing at DDR1800. I can still not get my 2x2GB 1800 MHz Dominators stable for even af few loops of SuperPi 32 M with loose timings. xt0m have been very kind to provide me all his settings for FSB 450, DDR1800 but these settings are not at all stable on my system (of course with an appropriate CPU multiplier corresponding to what I know my CPU can handle).Quote:

Sav, which slots do you put memory in the blue or the black ones? I just read a review of the memory I got (see sig): http://www.xbitlabs.com/articles/mem...800-4gb_2.html in which they write: "these modules will only work in black DIMM slots on ASUS mainboards". I put my sticks in the blue A1, B1 slots so I will test the black slots when I get back to work. I will give an update to this ASAP.
:D Same here - every morning when I get up and have to go to work......:rofl:Quote:

also with the dividers is the same problem, 1\1 and 1\2 nothing to say but if use another divider donīt boot :shrug:
lets wait for new bios revision it seems 0401 still very green or in this case very blue :p:
SaV good to see those corsair 4gb sticks, next month iīll probably buy and upgrade to a 4gb kit but for now just wanna wait and see the kits avaiable in the market and choose one that works fine with the mobo.
:up:
Putting the memory in the BLACK slots DID the trick. At least I completed a 32M SuperPi in the first attempt at 450x8.5 DDR1800 after changing the memory from the blue to the black slots. Need to tweak and test much more to truely stabilize but I am very happy since when using the blue slots I never came close to finishing this simple test irrespective of CPU speed.Quote:

I will post settings when I can claim they are stable.

After some more testing it seems that there is nothing wrong with BIOS 0501 as compared to 0401, which I found very stabile. It also seems that at least SuperPI is benchable on higher MHz with 0501 than 0401 as I now managed to run 1 Mill. at 4,909,5 and also managed to CPU-Z verify at a higher frequency as well (4.983MHz). All runs on my 24/7 machine with a :banana::banana::banana::banana: loads of processes running in the background and with no tweaking of disk or Vista Ultimate what so ever.

3) I advice to use Memtest 86+ v. 2.01 to test when tweaking for the right settings - errors will come fast (especially test 5) and you have a good idea what is causing the errors.
4) 1N is possible.
5) You need 1.5+ NB voltage (and I suggest active or watercooling on NB).
I have spent a LOT of time (and godwill from xt0m, thanks) trying to run DDR1800 stable. I wasted a lot of time Priming (e.g. 7 h stable blend test that suddenly would give an BSOD at ordinary use) at settings that made errors within few minutes in Memtest. Therefore I will not yet brag about beeing stable at that speed. However, now I have found settings at 9x450, DDR1800 cabable of completing at least 2 full passes. Tomorrow I will tell if it is truely stable in Memtest and then I will Prime to see whether the settings are stable in Windows when the CPU is loaded as well.
I'm sure you can't wait until tomorrow to se my settings so here they are (even though I can not claim they are truely stable yet or the voltages can not be lowered):
