First thing I did after testing the volts with a DMM was to set QPI to like 1.45 and Vcore to 1.45 and keep hitting the + until it Blue screened

Mega Shadow with two Ultra Kaze 3000's on it

But your not stress testing so even 1.4v's should be fine just to see what CPU-Z you can get.

Wholly Gale Force Batman! Can't hear ya for the wind noise!

The X58A bios had the Intel HS fan flat out by default - 2560 rpm - so for the first time ever I actually turned auto fan control ON.... Stock fan has an annoying sound ... even on auto ... goes up and down for no obvious reason too....good thing it's the depths of sub-tropical winter...frost yesterday morn..

The Corsair ram fans are rubbish! My old Dominator DDR2 ones died after two years. These Dominator GT fans vibrate. Can't be good for the RAM. Probably take them off. Not needed anyway, just bling.

Only two bluescreens, a 101 BSOD for the 4GHz button vcore which set 1.26v, and a 9C BSOD for the ram turbo / xmp profile-1 / 1.34v QPI/Vtt, so turned the turbo and xmp profile-1 off and all happy for last eight hours. Ah, new toy joy!

Footnote: Had to cut a little out of the backplate so the PSU would fit, and cut a couple of notches in the mobo tray so that heatsink bolts were accessible without removing tray. Lian Li was quite a puzzle to assemble with the bags of mixed nuts.

Question:

why do people turn hyper threading off?

only answer I can think of:

compatibility issues although I've never come across any :S

With HT off you can shoot for higher clocks and some games preffer a higher clock speed rather than lots of cores/threads.

Also if your having a bit of a heat wave in your area you can turn HT off to drop temps.

They are on a Lamptron FC5 fan controller and only used for testing.

Well depends on what you consider "compatibility issues"

As posted above, games will respond to higher clock speeds, specially when compared on a dual gpu setup like you have.
Anything that is not coded for 8 threads is technically "not compatible" however they work just fine. They just do not take advantage of the power.
To the best of my knowledge there are not many, if any games coded for more than 4 threads. If you do some testing, open task manager and leave it in the backround, then play some games and ALT + Tab out and look at your cpu usage. Not many will be pushing more than 4 cores, leaving the 4 HT threads at idle.
So if you can reduce heat and bump up the MHz it may help...


However, other testing I have seen shows that you need some serious GPU power to see any gains in a i7 past 3.8 - 4.0 GHz. If you test a 950 @ 4.0 with a 460 vs a 950 @ 4.4 with a 460 you wont see much difference in FPS in games being the 950 @ 4.0 has already maxed out your card.

However being your on a dual card setup you may get the benefit.

Hyper Threading ony helps in apps that are coded for multi threads. I run a program called DVD Rebuilder Pro, it has commercial encoders for DVD encoding that will run 8 instances and max my CPU out for video encoding, it cut my DVD encoding jobs by about 35 - 40% in times. What would take me 35 - 40 minutes with my Q9550 @ 4.25 only takes me 17 minutes with my 950 @ 4.25..

So many variables so much to tinker with. How'd you do?

Yes, the default fans are crap. I removed one side piece and installed 2 new Evercool Aluminum LED fans that I run at 7v. They work great! Used nylon thumb nuts and screws to mount them.
