You can install the utility softwares under vista using compatibility mode. right-click the .exe, properties, compatibility, etc. etc. hope this helps.

Hey! That's great news...thanks for posting it! I really just want Vista on my new PC. :)

So I upped the vcore thinking maybe it just wasn't getting enough juice but now it just reboots faster. It's really weird as I can hit 3.6GHz pretty easy with 1.42V (1.475V set in bios) and it is Orthos stable for awhile but eventually reboots. If I try to up the vcore than it just reboots again only quicker than before.

I've tested the memory timings using memtest and they run forever. I've tried different multis to get the same speed thinking maybe the fsb was limiting it but I get the same results. I'm running a good quality 600W PSU that didn't even break a sweat with my overclocked Crossfire setup (pulled 580W from the wallplate at max load) so I don't think that is the issue.

I'm kind of at a loss as to what to do. The chip seems to run great but I just get weird results when trying to raise vcore. I can game all day at 3.6GHz@1.42V (of course I'm only utilizing maybe 1.5 cores). Any ideas?

The fact your machine is rebooting quicker everytime you increase Vcore may indicate a temp issue. Those Quads can generate alot of heat. May help to diagnose the problem if you provide the CPU load temps.

For a simple test, try lowering your room temp (open some windows, etc.) and see if ORTHOS can run longer with the same voltage settings.

chipset cooling ?

I've had similar issue and a fan over the stock chipset cooler helped

I have pretty good airflow over the chipset with two 120x38mm Sanyo Denki's sitting right in front of the board. I also thought that if I tried say 11x327 instead of 10x360 that it would place less strain on the chipset and rule that out as the culprit. Am I correct in that thinking?

Temps are 55C with all four cores loaded at 3.4GHz@1.34V. Temps don't seem to vary with increasing vcore. It's kind of weird.

I tried everything you can imagine to get it to save properly and it kept resetting to 800 5-5-5-15 1.84v.

Sometimes the BIOS after 2333 will reset ram to "auto" when I first change an OC and a second attempt works to save correctly. It will tell me to check the BIOS and I enter to find 800 5-5-5-15 forced. I then change it as I wish, save, and it holds properly.

The only way I could manipulate memory and have it save with 2507 was to leave the processor section overclocking to "no" or off.

---

I'm no expert whatsoever, but I was suffering from the same problem as you. I solved it by setting my processor and memory to automatic first (so no overclocking at all). then I underclocked my memory to the desired setting. Mem Ref 266 and mem freq 533 plus desired voltage etc (I have 800 mhz memory) Restart the system and then change the fsb.
In that order the mem settings were saved and I was able to overclcok my system

Did one fresh install and one upgrade from XP Pro...

The Intel RAID, Intel Chipset, Intel Lan and Sigmatel Audio drivers from Vista all work with the following notes... The Intel Matrix Storage manager won't work because the Vista driver is newer than the Intel supplied one (no big deal). The Audio driver will have problems on upgrade if you don't completely wipe out the Intel supplied driver before the upgrade. Before you uninstall it, get the driver details, then make sure there are no traces left of those files after the unistall.

The Marvell isn't supported yet natively but the drivers supplied by Intel (including the Marvell console) work fine.

IDCC won't install even in compatability mode.
IDU is OK.
TAT is OK.

I read the first 10 pages and the last 7 pages.

So this board does not allow for multiplier adjustment.

Are there any programs that can be used to change fsb in windows?

Clockgen possibly? if so, which pll?

It's all fine now with 2507:

I turned the following off; Watchdog, C1E, EIST and VT. Watchdog and C1E may be accesssed by moving the jumper and entering the BIOS then.

Great!

I could overclock a bit more (3.6mhz) but my temps were getting higher then 63C in Orthos with full load. Am unsure if that's to high so I'm sticking to 3,2 Mhz

Not yet on Clockgen. The Intel Desktop Control Center will though.

Thanks! I'll give that a try.

Wish there was a way to access lower mults...

9 x 400 would be sweet vs. 10 x 360 :(

guys i just put this board in my system .. swapped out the 680i cuz it was dead ..

badaxe 2 rev 505 .. latest bios .. running a e6400 .. cou has done up to 3.6 on the 680i

no matter what i cannot get past bios at any overclocking ..

it always brings me to a screen that says

something about the POST having problems
press Y to enter bios or press N to try and boot with previous settings ??

no matter what i cant get past that screen

someone needs to write a guide :)

put the jumper in "maintenance mode"

then turn off C1E and Watchdog

then overclock to hearts content! :)

Took the pelt back off and all was fine again. Any help would be great. thanx

Can anyone see my posts"? cus i seem to be helping many on here but no one seems to want to help me. Its a simple question. Does anyone know what the cpu led located near the rear fan power connector on the 975xbx2 is for. what is its function"?

---

I have been digging around some of the documentation that I downloaded and all I can find is this:

In addition to the standby power indicator, the board contains two LEDs that indicate
the following:

Quote:

---

• The CPU LED indicates an elevated temperature on the processor that could effect
performance
• The VR LED indicates an elevated temperature in the processor voltage regulator
circuit that could effect performance
Figure 16 shows the locations of the LEDs.

---

My guess is that the pelt is making the sensor go out of range at startup, some fine tuning must be needed.

did that .. still no go .. dunno why

weird. i was stuck at 3.0 ghz.

after i turned off watchdog, i'm now at 3.7

can someone help me out real quick? i've been looking for that Intel sheet that has the BIOS post codes on it ("BA" "00" etc) and I can't find it. If anyone knows where it is, could you please post the link?

Thanks

you ARE the BX2 man! :)

I've only had this board for 2 days now and I'm lovin' it!

This board should hold me over nicely until I'm forced to change chipsets again... <sigh> *I HATE INTEL ONLY WHEN THEY FORCE ME TO CHANGE CHIPSETS*

There any better places to buy from other than this deal? Tempted to pull the trigger

At the moment, this is the best price. The next cheapest is tigerdirect for $199.

Wow...

I've been able to run 4ghz fine before on air, but on 1333 strap.

Last night I vmch mod

Boot up to install xp on a 40gb IDE drive to bench

normal xp pro and nlite'd xp pro black screen

xp x64 works fine

4ghz doesn't post at all

get it to run stock, flash 2507 from 2333

Watch dog at every clock

disable watch dog, stock doesn't post

post stock with 1 stick of memory and get 3.6 working again

4ghz doesn't post at all

The ability to have this board POST is just awful. It NEEDS clockgen. I love the board, it's fast, it's stable, but pushing an OC on it is a nightmare and I'm on the verge of selling it for a commando :(

keep this board mate ;)

Why should I? Every time I try to OC it I get to pissed off to think straight.

Now my old 3dmark stable clock of 3946mhz freezes idling windows. Did my CPU degrade? Wtf? My old 6600 did the same thing, 3700 ran fine 24/7 for 2 weeks then only 3600 worked.
