I, too, had a bad board to start with. One RMA and I seem to be ok (so far...).

So what we want is LLC to auto-enable when the CPU is working - kind of opposite of what C1E/EIST do!

So I've been reading this post for a few days and since I finally have some questions I decided to post.

My new system will arrive on Tuesday and here it is:
Q6600
Corsair XMS2 2x2Gb 7-7-7-20 @ 1066 or 6-6-6-18 @ 800- 2.0V all
WD Raptor w/ XP
750W PC&Power PSU
Zalman 9500at HS
2 120mm Rexus fans & 1 Vantec 80mm
Lian Li PC-7B case
of course the GA-EP45-UD3R (will not do gaming)
MSI N9600GT

I will do a lot of video encoding and multitasking which is why OC is an option (as well as the capacity of the board and chip)

I have my boot USB ready for the f6 bios, and will likely lap the heatsink.

What limitations may I encounter?

3.2 and 3.0 seem to be my best options- both at 8x multiplier and voltage probably set to 1.3 to start w/ 400fsb for the former and 375 for the latter.

This post is relatively vague, I know that, but the last system I built and OC'ed is the 2.4 to 3.0 that I'm typing on right now. It's been a long while but this p4s800 has held up.

Any suggestions would be great- this board really feels like I made the right choice on my budget and I want to fully take advantage of it. I hear the cooler may not be so great, but I can't take back my purchase.

Lemme know- I will post numbers as soon as it is built.

Kinda easier said than done, though i'd love to do that.

I'd have to spend all that money & then have to sell a perfectly good 8 GB of Mushkin for basically nothing...if i wanted to be buying a new mobo & RAM, i almost might as well just go i7...

Actually we've seen zero screenshots indicating quads + 8 GB Blend stable at high FSBs.
I'm not saying people are lying, but screenshots speak volumes, especially if people include their settings + ET6 in the screenie.

As i asked earlier, seeing your BIOS template would be a huge help to me, as it'd be from someone with the same RAM.

And what stability testing did it pass for how long?

I'm not trying to say this board is bad per say; there's no doubt this is a really strong board for quad clocking, no question.

But if memory is an issue, then why does it pass Memtest86+ just fine?

I will continue fighting with this mobo in the hopes i eventually find some magical settings that work.
But i'm not going to lie, when i have settings that pass 10+ hours or P95 Blend one day & then fail within minutes the next day, i lose some hope.
And the broken sleep mode, & flakiness when POSTing or sometimes not POSTing on "stable" results isn't very consoling either.

I do however greatly appreciate all the help people have provided

I had those problems with a bad PSU or video card- replaced them both and it went away completely. Don't know which was the culprit, but I did have unstable voltages from the PSU when I first bought it.

I have swapped that board out in favor of my EVGA 680i SLI as the problem was just driving me nuts. I really don't want to go through the trouble of trying to swap the Gigabyte back in unless I feel that I have a real chance at fixing this, so if you have anything more concrete, please let me know. Otherwise, I have an RMA from Newegg and it will go out tomorrow (I really don't want to ship it off :/).

Ahh - I realize this is almost a zombie topic by now, but was this ever resolved? I suppose by now the board has already gone back to Newegg.

I had a very similar problem with my UD3r - occasional system wide hiccups. By any chance were you using a PATA drive of any sort? While my hiccups were not on a 6 second timer, they were happening at least twice a minute. My primary boot hard drive and cd burner are connected via standard PATA IDE cables. The problem is caused by the JMICRON sata/pata controller. (Gigabyte calls it their "sata2" chip) With the default driver installed off the disk it is set up in "hot-pluggable sata raid" mode - which has the unfortunate side effect of confusing windows into believing that any IDE devices connected to the PATA port are "SCSI" drives, and so windows configures them as PIO devices, rather than DMA, which causes hiccups.

The solution is to download the latest standalone driver install program for the chip in question and when running it's installer select the option for GENERIC IDE mode, rather than RAID. Depending on which version of this installer you get, it may not ask you this unless you dig into it's .inf settings file and set a 0 to a 1 to make it ask.

Yes, you lose hot-swappable SATA raid on two of the sata ports, but no more hiccups for those of us using IDE drives!

I JUST bought this motherboard as a step-by-step upgrade of my machine, as I can still run my Prescott P4 on it until my E8500 arrives in a week

So no overclock yet

Durr - gotta read through the whole thread before bringing up solutions to already fixed problems. Gratz on the working second board!

Thanks for the suggestion, but no matter what I tried I could not get that board to stop giving me that problem (and, yes, that includes clearing the CMOS back to defaults as well as downloading all the latest drivers).

I had a bit of a scare on my second board where it started to do the same thing, but I was somehow able to stop it (I just took out all my PCI cards, booted and it worked. I put them all back in and it continued to work).

I just hope I don't have to worry about this anymore.

Haha, no worries. This thread has become so long and unruly that I have stopped expecting people to know what's going on. Good luck on your second board!

Just got my new E8500 E0 from guy on eBay..

WOW..

4.25Ghz the first shot stable (well I need to fully run Orthos but was stable 5 mins or so to grab screenie and post here)

Very, very nice.

Stuck sensors so can't say idle but with the AC7 Pro w/ AS5 re-applied it was loading out @ around 50c
