Hi guys, brand new on XtremeSystems.
First, excuse my poor english, Molière is easier for me than Sheakspeare (frenchies and others languages...).
Second, big, big and big thanks for all and your replies, helps me fully to find stable oc.
Third: how to get sig on this forum?
And last, screens about my system :

good stable clock there mate :) bien fait
For ya signature go to USER CP ( top of ya screen ) and edit signature there
Thanks, mate. Done for sig. Merki !

SLI @ P45. If anyone has my already SLI Patches BIOS, then go for it!
hi EVO, you mean your 1901 patched bios?Quote:

Can't wait to give these a go on this board, although I don't expect very high memory clocks with 8GB, but it'll be nice to stretch this board's legs a bit, and be able to compare against a few more rigs in this thread.... Watch this space :)
After this I'm done spending cash on it for at least 2 years!
If you get the right memory it will do 1200mhz with 8GB.
This Mobo is simply picky, I cannot even get past 1175MHZ with 1 stick but these sticks can do 1200mhz in other Mobos (older Rev Corsair Modules).
Getting off the 1:1 Ratio may lighten the load on the NB and let you get 500FSB on the new Quad.
If I were you I would have either gotten the newer 1200mhz OCZ (1.85v) or the 1200mhz G.Skill Trident (1.80v)
I did hunt around for 1200MHz ram, but the only stuff I could find that were specced at decent timings (i.e. 5-5-5-15) and were in stock were the GSkill PI's which I know are among the best DDR2, but I couldn't justify paying double the price for them. There's not much info on their ripjaws, and the timings didn't fill me with confidence either, but I do admit they would look good on the MIIF. The blades are likely to do 1200MHz according to some buyer reviews (one guy reached 1300 5-5-5-18), but with 4 sticks, and this board, who knows?! :)
The fact is that I bought all these parts on a 'buy now pay in 12 months' scheme, which meant my choice was limited to one shop, but I'm happy with what I got, and I hope it'll all be with me on friday. I'm feeling pretty confident some reasonable clocks are on the way and I will be certain to report my findings! :D
yeah, i mean my SLI patched 1901 BIOS which i made many months ago ... i think there must be a link somewhere inside this thread :p

Don't care any more but that was a great stuff to test :D ...Enjoy MIIF Ownaz ^^
Heres a pic of my MIIF running small FTT's @ 550mhz...trying to get Blend test stable with PL12/13 now.

Just curious if anyone is running over 570mhz FSB..and if so, did Skew or GTL's get the extra 'mile'..? I can boot up to ~590mhz, with NB air cooled..PL14 @ 1.55v...just trying to find some NB stability over 550mhz is tough. :(
I was doing 560. It is a really nice overclocking board. Anything more was not stable.
Seems like you're encroaching on some nice stable fsb speeds. I wasn't really going for stability when I tried an E8400 in there, but tuning the NB & CPU clock skews can really help at high fsb. They're quite easy to find, and in most cases the NB is better off being delayed more than the CPU.Quote:

I've also had lots more rounding errors rather than the reboots and hangs I used to get before, much happier now. Can't wait for my Q9650 and 8Gb of blades!
So far, the following settings have made stability a reality at 540mhz FSB..
NB clock skew- delay 100ps
CPU clock skew- delay 100ps
RAM skews as follows:
advance 100ps
delay100ps
delay100ps
delay100ps
vcore- 1.43
FSBv- 1.35
PLLv- 1.75
NBv- 1.52
SB1.1- 1.16
SB1.5- 1.51
CPU GTL's:
+50mv
+10mv
+50mv
+10mv
NB GTL- -50mv
I am currently on PL13, with booster set to 'moderate'...tweaking further with latency is crapping out the NB still..but I am getting close. Now 4hr Blend stable.
Good work, keep going, I'm sure you'll get there eventually! How did you go about tuning your ram skews? It's the one thing I never got around to doing with my last board. 100/100 on the skew actually seems about right, my suggestion to delay the NB more came from having a quad, but if I remember correctly normal/100 worked best for me with the E8400.
Your NB and DDR Refs might seal the deal if you tune those up, but they're not as easy to find as the skews.
How are you cooling the NB? Temp seems really low for 1.5v+ and I'm getting much higher temps with lower volts and a waterblock on it!?!
For the RAM skews, I was noticing the 'fine clock delay' in Everest..displaying the following for the RAM slots:
6T
2T
2T
4T
....Some bandwidth testing with 1x stick in the different RAM slots, showed me similar results with the latency of the different RAM slots @ a given speed/timing set. It was then, I started advancing the skew for the first slot, as I believe it to have a higher skew by default [maybe due to the difference in trace length in the mobo..]. It has worked great! ...and Delaying the skew on the other slots/channels has gotten me a smidge further in tightening down NB latency as well. Without RAM skews set, my NB is not stable with Clock Twister set to 'Moderate'...with skews set, I have gone just over 4hrs in Blend without errors [stopped test for moar tuning..not due to errors].
As for DDR Ref I leave mine set for +.35mv for speeds over 1100mhz..and set NB Ref to 'Auto' still.
*My NB temp is most likely false..as there is a 80mm fan sitting on it. :D I got 545mhz last night...but was having random lock-ups [no BSOD]..gonna try again later with ~1.8v PLL and see how it goes.
..quick Pi run at 556mhz FSB, PL14 and loose timings
http://i265.photobucket.com/albums/i...13sec_1mil.jpg
and a even quicker PiFast run at 570mhz FSB, PL14 no timing adjustment.
http://i265.photobucket.com/albums/i...4sec_hexus.jpg
..will push for better FSB, once my chiller is operational again.
CL3P20
Awesome. Can you show your chiller tems, just interesting :up:
....pics of the rev2 chiller ready for lead testing...then CPU and GPU will get sealed up better. Hoping for -70c with the changes I made from last time. :D

Hehe, uber-cool stuff. Did the skews help you get there at all? I got past 600fsb and managed a 1M PI run with an E8400, but couldn't bust the 10s mark.
I had a little fiddle with the ram skews though, seems like A1 at advance 150, and B1 at advance 50 gave me the least memtest #5 errors. I'm gonna try & set them tonight and see if I can push past 1200, seems pointless when CPU & RAM will (hopefully) be replaced soon.
Yes, I'm STILL waiting for my order to arrive - 3 weeks now, and it's doing my nut :(

Insane rig :up:
Hi guys, I gave that SLI hack a shot on my MIIF
Hardware used, Maximus II Formula / E8600 / 2x2 OCZ Reaper ver3 PC-8500 / XFX 9800GTX Black Edition
E8600 @ 450 4,05, 2x2 OCZ Reaper PC-8500 @ 1080 555 15 tRD 8 strong
Here´s how I did it.
1 - Install Win7 RC x64.
2 - Install System and 191.07 Win7 x64 (WHQL) drivers.
3 - Disable UAC.
4 - Restart.
5 - Run SLI String Installer v1.81 as Admin select ASUS certificate.
6 - Run HAL Mod 0.9a as Admin
7 - Copy moded nvlddmkm.sys (rev2) Win7 x64 to C:\windows\system32\drivers\
8 - Sign the nvlddmkm.sys with the Driver Signature Enforcement Overrider, select "Sign a System File", type in C:\windows\system32\drivers\nvlddmkm.sys
( Check out this for more info, Activating NVIDIA SLI on all motherboards, detailed HOW-TO )
Reboot, and we have a SLI capable system

That was it, pretty good scaling for a couple of old 9800GTX I most say
:eek: Woot!! I will have to give that a shot...and see how 8800GS SLI plays on the MIIF. :D *btw..got the chiller running yesterday.. @ -54c :up: Still tuning latency on PL12 between 540-570mhz [talk about tough] I really need a NB pot for this mobo to see decent latency at this FSB. NB is just fine with 1.48v ..but temps must be below 20c to hold 3D stable..
quick pic and bench
http://i265.photobucket.com/albums/i...x/P1060391.jpg
http://i265.photobucket.com/albums/i...x/P1060382.jpg
lowered the Pi time a bit..still tuning for 9.0/sub8's though..
http://i265.photobucket.com/albums/i...235sec1mil.jpg
..also ran AM3 with my GS and E8400 @ 4.9ghz..managed 7th overall :D ..will definitely be tuning for lower ranking now!

@ Ghostleader..bookmarked your post.. if I have any issues once I get around to the hack, I shoot you a PM.
