Passed all tests till 23 then failed upping to 1.46 lets see....

I have news, i noticed that in occt the test was called large ffts so i tough well this test is mainly for rams/chipset , so i run orthos cpu test, and didnt get an error , swapped the orthos test to the memory test (large test) and bang error 1 sec!
So the conclusion is that the problem is indeed in the chipset!
Now i changed the strap from 2.4 b (333) to 2.0 (400) hoping that it would relax some timings in the chipset and hell now it passes 4 tests then fail.
So i guess its more stable, btw i forgot to say that i know its the chipset cause the rams pass 4 loops on memtest96 so....
Iam running vtt @ 1.32 pll @ 1.5 cpu ref @ auto mch @ 1.38 mch ref @ 0.726
Advanced: 900 900 0 50...
Going to up volts on mch and rams to see if that helps brb!

So i upped the ram to 2.32 and mch to 2.42 it was passing every test and in the 9th i got bsod !
So iam thinking the mch isnt having enough juice uped to 1.44v lets see how that works!

lets test on same basis...dld prime 25.11 and run custom 8 to 8k...see if that passes, is so, shoot a normal BLEND

if more MCH helped then u have a clue there, if BSOD then notch vcore a bit...in my 2 GIGA boards when pushing hard timmings i always need more vdimm, more MCH and notch vcore...

also try what radaja said

"mine liked it like this.with vtt at 1.28v cpu ref at normal(0.760) and mch at 0.750 bios"

references are important, so skews

Cheers

improving

notch vcore, plz tell me at what speed are you runing and multi, and also on what mem divider /turbo/standard are you mate

turbo setting ram 4-4-4-14 1000 mhz pl8 @ 2.32 v
cpu termination voltage 1.32
pll 1.5
cpu ref -auto
mch voltage 1.46
mch ref 0.726
Advanced settings
900
900
0
50
9x500 =4500
It´s passing every test @ large in place ffts priority 9 its now doing
test 7 768k fft length @ 38 minutes , so in fact upping the mch is helping...
But without changing the strap(2.00d/400 mhz) i would still be in a dead end...
Hope it holds up till the end.
Cheers mate.

glad to help you can try 5-4-4-9 also

glad to help you can try 5-4-4-9 also

This mems hold up cas 4 pretty well...
I got some good and bad news the system its now stable for a hour , guess i nedd just a little more juice on mch maybe 1.48...
Orthos failed just after saving this SS:

It´s 00:16 here in portugal... but i will try 1.48 to see if it´s enough to pass more hours in orthos...

ANOTHER LONG NIGHT!

BAD NEWS:
Last night with the sttings above started to do some strange things like, everytime i changed a setting in bios pc shuted down back up shuts down back up shuts down , and back up with the OC settings not with the safe ones and then it booted fine....
So i was tired by so many "reboots" that i cleared cmos all night and switched to the f8 bios.
Puted the settings back on and the same thing occured .
Then i used optimized settings and the rebooting was gone then i start outing the settings one by one to find what was causing this reboots , then i concluded that the only setting that was causing this was the cpu ref!
So i must assume that the reboot was cause by some bad relation with cpu and mch ref, so now i have cpu ref @ AUTO and iam increasing the mch ref!
Andre whats the safe max 24/7 for mch ref?
BTW this is my solution to cool the MCH :

its normal on GIGA boards to reboot loop dont be scared, when you screw bad with some refs, skews or timmings will do that...just power off psu for a while if that dont work CLR CMOS

dunno what the safest i just use what it needs less than 1,56, im on 1,52 but for tight PL7 needs a bit more

cheers

yeah my pl8 was messing my mch voltage a bit now testing @ 1.460 pl 10 its 1:30 h stable , but i think i can decrease the mch voltage a bit....
Using cpu ref @ auto and mch ref @ 0.853

[MrDucky]

can annyone else do the everest test on 4.25 ghz with 500 fsb or other settings just so i can comare my scores...

[Hoss331]

Im assuming for ddr2 and what speed are you looking for?

1250 C5 PL8

4250 at 500FSB he got a 9550 hoss

[MrDucky]

omg your l2 cache speeds are so freaking high my write only goes to about 14k ....

[Hoss331]

4250 at 500FSB he got a 9550 hoss

The difference on the memory scores will be minimal, like 50mbs on the reads and ~0.3ns on latency. If hes wanting to compare cache then no it wont be very comparable.

omg your l2 cache speeds are so freaking high my write only goes to about 14k ....

14k does seem very low for your speed, I would think you would be atleast in the 20K area.

[MrDucky]

well it isnt could it be my windows install or maybe nto stable enough?? cause it is prime stable....

[andressergio]

Blending this config that i will keep for my 24/7

X3380@ 4500Mhz
ST @ 1600 6-6-6-18 trfc 52 / PL7



Cheers and GO GO URUGUAY !!! TOMORROW AGAINST KOREA

damn sergio thats a super fast p45 board that ddr 3 is running ddr 2 settings amazing fast .... can we see some i7 challenges lol im sure you made the bandwidth up

Amazing timings Sergio

I was going to have a play with my ram today, but my board is back to not posting. I don't know what it's problem is.

sorry to hear mate, did u inspect the board as we talked ?

[jjjc_93]

Yeah, I can't see any signs of physical damage at all.

It works fine when it does post, but getting it to post is a whole other story.
