Niiice, what's your OC on RAMs and CPU?

I hit that score at 3,70GHz and the GPUs at stock 700/1000.

Out of the thread... aaaw, this is no longer Al Pacino's Mobo?

3D mark 27.0% gain

temps never above 61C for any core
overall CPU 41c max
did not add ice to reserator tower (although I really want to try that someday).

I have some room to play some more, and may at somepoint, b ut for now I got what I wanted to see so back to default settings for me. May stick around for a bit though. one of the calmer threads on boards I have seen.
FSB voltage is on the high side no??? I been trying to get mine stable with 900mhz ram but couldn't. I guess that's the secret huh? Im running mine at 450x8 with ram at 800mhz with 4-4-4-12 timing and 1.45v at the core and 1.4 FSB with GTRLEF's adjusted!!!. Sorry to say but this board is horrible for extreme oc's.

But TBH on these boards I've noticed the best strap ('sweet spot') is at 1470 fsb.(3.3ghz with 1066mhz ram speed) It actually feels faster than 1800fsb. My memory read is at 10 GB/s with 50.7ns latency. 1800QDR couldn't even touch that.

Well, I've been running 4.00GHz for awhile, and it was always stable in stability tests, but my steam games have been crashing a LOT. Well, I did some testing, and found it beneficial to actually lower my overclock. Not only is the system completely stable, my games are no longer crashing, and my voltages are a LOT lower.

Here are my current BIOs settings:

1333MHz
333MHz x 11.5 = 3.83GHz
vCORE = 1.3750v
FSB = 1.10v
DRAM = 2.100v
SPP = 1.40v

I'm going to do some more testing, and attempt to get the vCore even lower. Right now I am satisfied with the overclock, because being an engineering sample, it can be hard to overclock it. Also, I showed zero difference between 3.83GHz and 4.00GHz during in game stress testing.

Final update
After some long testing, I got my voltages as low as possible, and stable. Here are the results:

1333MHz
333MHz x 11.5 = 3.83GHz
vCORE = 1.36875v (1.344v after vdroop)
FSB = 1.10v
DRAM = 2.100v
SPP = 1.30v

I was hoping to get even lower than that with vCore, but being an Engineering Sample, I can't complain I guess.

I have never seen a need to put the 9600's on water, they rarely get above 75C. They stay cool enough to where (I think) there is only one compnay that makes a full cover water block for them. To me 9600 on water is more for look than effect. 9800's oh hell yeah I would, 9600 naw.

So thinking of trying to get above the 3.6 I got last weekend. I stayed pretty light on th evoltage and think I can get above it with same voltages I used before. Will see when I get inspired.

Heh, no need for a full cover block. The Hynix memory chips are not going to OC well even if kept cool. I felt a need to put them on water so I could OC the poo out of them. When I hit 850Mhz they where scoring as well as my 8800Ultra I use to have. Like to see someone hit 900Mhz with these puppies on air.

Another Update
With the last settings I listed, I ended up blue screening when I tried to shutdown the machine. It gave me a BAD_POOL_HEADER error, and would not dump the physical memory. I did a reset, and figured it to be a fluke. After bringing it back up, I started running Prime95. It ran for 2 hours no problem, so I left it to run. I came back about 3 hours later to a blue screen, so I went ahead and upped the vCore back to 1.3750v in BIOs, which gives me 1.352v after vdroop. I'm going to leave Prime95 running overnight, and hopefully not wake up to a blue screen.

Do it with Liquid Nitrogen. Cant be too hard to mod this baby.

http://www.koolance.com/water-coolin...product_id=899

also check out the CPU liquid nitrogen evap they have. Wont work too well with a tower case and the height woudl lead me to believe the case would have be open to accomidate the CPU evap. Somethign about an open tube of Liquid Nitrgen kinda bugs me. Especially with 4 VERY nosy dogs running about. I wonder what the ice buildup is around these?

question here for those that have a 750i with Q6600 G0 and use Everest.
Is everyone showing core temps at 10C below real? Everest seems to report it at 90C TJMax (which is fine for a Q6600 B3) but the G0 is 100C spec. Every other program, Nvidia sysmon, Speedfan, Coretemp all show it as what it should be. Is it just mine it shows wrong on or is this norm?

Brian

Edited to define norm (normal). Not that any program should improperly report core temps (that is just wrong) but by norm I mean is everyone with this combination of MB and CPU showign what I see?

Nop, the G0 target TJmax is 90C. Here it is from Intel's site.
