Testing / comparing : Intel D975XBX2 / Asus P5B DX ***56K WARNING***

[aamsel]

Thanks, but is this SPDT switch or what?
I looked, but this was not mentioned on GTJ's BX2 page.

Andrew

I mean a clear cmos / normal mode switch

sorry for crappy quality



I used a switch and old wires from a case (Power Led)

you can mount the switch on your case also

Another thing to remember, although it was me that started the C1E thing, this is by no means a critical bug. It's an annoyance. Use RmClock and it will disable C1E whenever you reboot.

RmClock can be set to disable C1E when starting windows or do you have to manual set it each time you boot your system?

i'm not sure but there might be an option that allows you to startup rmclock on startup, else you have to enable it each time you enter windows.

You can set rmclock to start at windows startup and also set it to apply C1E when it does.

thanks..so this appears to be the only solution to C1E disable issue

[KMEI]

can someone explain what straps does? from what I've figured, the main three are 1333 1066 and 800. Which one is faster and which one is best to use?

Also, are you supposed to ADD power to that 4pin molex connector to the left of the nb? I have a fan connected atm, lol.

some good strap info located here.
strap 1066 will give you the best performance in my opinion. checkout GTJ's BADAXE2 Calculator & his BADAXE2 Guide both should help in your mission to juice this great board.

Should I disable VT/XT when OCing

I would suggest you read this BAD AXE 2 guide by gtj

So is this C1E not disabling causing overclocks to be unstable with general use..seems like it would be a big issue on this mobo and overclocking....

although everyone in general seems to be happy with the mobo and its performance/stability....just not alot of "exotic" bios options

[hotchoc]

You can try using RMclock to disable the C1E thingy and yes i have to agree on the bios options. Compared to my previous DQ6 and P5B Deluxe, i was kinda surprised at the simplicity of the bx2's bios. It is after all an Intel board

Are you suggesting that is does not work well as a "fix" for this issue which Intel could careless about

[likewhoa]

nealh it works with RMClock. just set it to disable on startup.

thanks..the impression I got(which was wrong..sorry) was that it may not work well

I am going to order this board as a replacement to the second bad RD600

yes it is a SPDT switch.

Any ideas guys:

vcore = 1.375
vfsb = 1.3
vmch/ich = 1.55
fsb = 345X9

results: error in orthos in 2h 32m, stable in OCCT, XP

vcore = 1.375
vfsb = 1.3
vmch/ich = 1.575
fsb = 345X9

results: error in orthos in 42m, stable in OCCT, XP

Why would increasing the vmch/ich decrease the stability ? What should play with next ? Higher vcore or higher vfsb.vmch ?

p.s. Would have been great if either the vmch or vich can be manually adjusted separately like the p5b

i'm just shocked by your low fsb.

even with a locked 6700 , i can get 370 to 380 with no problem orthos stable.

again, is that chip capable of 3100mhz? only reason i can see as to why orthos would keep failing unless something is wrong with your mem.

[hotchoc]

Yeah, i really don't know why am i getting such low fsbs

Ram timings are set as 5-5-5-15 with 2.2V running at 1:1

It's a week L28B some more. Hwo do you know a chp is capable of the stated speed? i.e. >3.1 Ghz

Going to try memtest86+ now. What does it mean if there's an error? Bad ram ???

if you're running SMALL FFTs and it errors it's your CPU, if you're running Large FFTS or Blend Mode it could be both. rule out one or the other. run small ffts for cpu and memtest for ram, when both pass then run Orthos Blend Mode.

Thks for the tips

[argylesocks]

yes it is a SPDT switch.

not sure if it makes a diff - but i went with a spdt MOMENTARY switch...
so i have a 1-2, open, and 2-3 option

wired it up & put the switch inside the case

My opinion: C1E being on is only a problem while you're tuning and only if the multilier changing is confusing to you. I've never had an overclock problem with C1E on. Part of the reason may be that the 1 thing that Intel did right was to not allow C1E to change the Vcore if you set it to something other than the default. In this case, it only changes the multiplier.

You're about the same place I was with my E6600. I can do about 340 with stock Vcore but no more. I'd leave the Vmch and Vfsb alone and just move up on the Vcore for now.

I tried memtest86+ v1.70 for bout 5-10 mins and once i moved my mouse the whole system reboots.

Tried the second time and the same thing occurred - system reboot after moving the mouse. I don't see any ECC errors at all. Is this normal or is my ram screwed?

Will be trying the third time for at least 5-8hrs WITHOUT moving the mouse at all.

Wait, do you have ECC enabled in the bios for memory correction?
