I always thought the "system" was the NB temp?

If anyone is looking for a good deal on the SR2, Tiger Direct has it for $599 minus ($79) Bing Cash Back.

I'm not sure if any of them are NB-temp, I miss a better documentation.
I've been experimenting with air flow in several days, and ended up with one fan on each PWM, and it is keeping both system-temps pretty stable. Finally all temperatures seams to be OK with IOH=1.35v in closed case in July heat.
I'm going to try IOH=1.4v soon, and I hope the cooling will hold.

Just wait till you see my next batch of pictures I post. You will for sure have a good laugh at my cooling setup

Have you posted this question on the EVGA forums. They are pretty good at getting back to you, or at least someone there will. I am between this forum and theres a few times a day.

Looking forward to see the pictures. Some pretty nice builds so far. The case is my next big expense...you can spend 600 plus on a case in no time with this motherboard. Soon I will be joining all of you!

No, I don't have a EVGA-account yet, but I've checked EVGA-forum a few times. Several people got the MB but there is not much talk about OCing there. They seams to be too busy with 48GB .

I hope they can provide a better documentation and a new BOIS, soon. You can tell them about it, for me.

I am mostly concerned with my cpu-0 pwm temps as they stay pretty high 55-58c even with one of the asus mini mobo fans attached to it I have ordered a fb block from Bei Fei and I will update with pics and temps results, both before and after

Yeah that CPU#0 PWM is a nasty one, it gets really hot. Mine holds ~62'C under load, even with a fan right on top of it. But I guess that's rated for high-temp anyways.

IOH=1.4v got it to BCLK205 . It is amazing, anything over BCLK200 scores really good for the speed.
I don't know how stable this is, but at least holds for CB . Still testing and hopefully can get it 24/7 stable.

Breaking new personal record in CB 11.5
VVT=1.33/1.34v (Idle/load)

@SR-2 owners

Can help to run the x264 bench at this site? You need to install Avisynth, download & run the benchmark. The protocol is described there.

Some interesting results for comparison
http://www.techarp.com/showarticle.a...tno=520&pgno=7 Results of different cpus
http://www.techarp.com/showarticle.a...tno=669&pgno=0 More cpus, including overclocked 1P Xeons/Gulftowns
http://forum.doom9.org/showthread.ph...45#post1386445 Intel i7 980x 3.8GHz

It'll be great to know where Westmere stands in video encoding. Please leave a link where you post the results. Thanks.

PS: Turn off ECC, as it will give poorer results for 2nd pass.

Has anyone with an SR-2 had a chance to run PiFast?

[sRHunt3r]

I will give me a couple minutes

[sRHunt3r]

Pifast was a bit of a disappointment ......... my I7 920 @ 4.5 spanked my SR-2 dual X5680's @ 4.3


y-cruncher seamed to be better, here is the comparison screenshot:

Might be the case because PIFast is a single-threaded app...

found out today that despite what evga says you can run up to 96gb of ram in the sr2.

here's 80gb...

That's sick Fits ..... my rig uses at most 5 of the 12 I have in it while crunching. There must be some crazy memory intense apps out there, you know any examples

[Fitseries3]

haha.... final cut pro editing .r3d files.

yep... i've got OSX running on it... among other OSes.

[sRHunt3r]

Congrats man that is just pure POWA!!!!!!!!!

I'm really looking forward to getting the board on water as the board temps are scary high for 24/7 load.

For the time being I have a floor fan on my test bench

[Sam_oslo]

SR-2 doesn't use the typical classified cooling. Finns are too small and this MB needs active cooling, but it gets really crowded with tow CPU-coolers and it's not easy to add active cooling to it.

I've manged to squeeze a fan on each PWM, but there is no space for a fan on NB, between tow CPU-coolers. The CPU#0 PWM gets pretty toasty ~62'C under load even with a fan right on top of it, but I guess that's rated for high-temp and it won't cause any instability.

I don't know when stsytem2 (I guess that's NB-temp) gets unstable. It is keeping to ~47-49'C (Idle/load) and it means the heat-pipe is working fine to keep the temp pretty stable, but I don't know if it's too hot already. What kind of temp are you guys getting on System2?

[sRHunt3r]

My system is at 28c and system2 is 37c under 100% load crunching. CPU#0 varies from the high 50's to low 60's.

Could anyone here please confirm the minimum requirement to achieve full score (7.9) on processor in Windows 7 Experience Index?

[=[PULSAR]=]

Well after a little bit more tweaking I'm able to get in some runs of wprime 32m @ 4.94ghz on water which I think is rather impressive. The OS I was running was junk, so I need a new install. The current WR is 1.907 secs @ 5.07ghz. I was able to pull off a 1.96 @ 4.85ghz, so I feel with enough tweaking and perseverance I can get this done and get the gold cup back to where to belongs

Sniper, both my i7 920 @ 4.5 and my SR-2 with Dual X5680's @4.3 get 7.8 on the cpu and 7.9 on the memory

[Sam_oslo]

I don't think that w7-index is something accurate and trusty for the measurement of CPU performance, CB 11.5 and vPrime are much better.

MY 1600MHZ CL8 RAM scores 7.9, but both my w3520 @4.51GHz and 2 x X5650 @3.8GHz (and i tries up to 4Ghz) never could hit that, they are always at 7.8.
