yes, 2 rads with 12 GentleThypoon + 2 Scythe slim.
I stay in one of the hottest place in Msia. ambient is 34C.
In Kelantan I got 3C cooler.

yes but SB is a lot cooler and faster than bloomfeld.
u can't clock this high with the former, and with HT enabled somemore.
and let's don't forget this is not a golden chip yet and 2pcs of OCed GTX580 in SLI, in the same loop. I'm quite satisfied migrating from the dying bloomfield.

latest bios including old BIOS dl links can be found in my 1st post as well as the latest LinX, etc...

For F5 bios onwards, pls use the latest @BIOS V2.11
hwbot links there they already said "(use @BIOS V2.10 (?)? if you're flashing from pre-F5 bios: click)"

without internal PLL overvolt ur proc will be limited to 4.7-5.0 GHz only.
but enabling it will hurt S3 sleep/hibernate from waking up.
I always enable it 5.0 GHz onwards, if disabled I got random windows boot issue.
yeah read about the serious vdroop on UD3. with that price no one can complain
vCore depends on chip, my 4.8 HT @ 1.476v load on LinX, but some might get a better chip as low as 1.4v (envy)

- max vCore on air/Water single threaded benchmarks ie. Pi etc.. : 1.6V (short term only not 24/7, risky!)
- max vCore on air with 4C/8T 1.4-1.45v (may vary on speed)
- max vCore on Water with 4C/8T 1.5V (may vary on speed)
- vdimm 1.6-1.65V is fine, also 1.7-1.8V wont fry the chip on air yet
- lower your CPU PLL under 1.8v might be better as compared to the default 1.8v when OC past 5.0 GHz
- if u hv prob running higher dram speed ie. 1866 or 2133 or better timings try adjusting VCCSA between 1.0-1.1v
- VTT depends on chip, some is best doing at stock 1.05v, some need 1.2v etc to successfully boot.
- try loosening dram timings when having issues with high mem speed, specially TRCD and TREF

stasio advised above, flash the backup BIOS chip as well by pressing ALT-F12 during boot

dual channel is 128-bit, 4 sticks are still 4 channel hence the bus is still 128-bit.
4GBx2 is easier to clock coz populated dram slot (2GBx4) would need more vdimm, vtt and/or loosen timing ie. CL8 to CL9 etc..
Like my GSkill RipjawsX, 2GBx4 needed above 1.7v vdimm, higher vtt for 32M benchable.
unless if loosen timing then only u can tame the voltages.

U might consider Corsair Vengeance 1600MHz 4GBx2 1600 8-8-8-24

Make sure that ur windows is x64 (64bit), if not the x86 32bit windows will recognize as 3GB only
4GB should be enough for those purposes, but it wont hurt if u hv 8GB. Burst speed. 8GB is not a waste.
Hardcore photoshoper should go for 8GB, if u noticed the mem usage is increasing during photoshoping. Adobe engineer recommends mem usage not exceeding 70%.
Gaming, nowadays mostly will utilize up to 1.5GB only, the only game that i encountered consumes more than 2GB is Crysis. 3GB kit confirmed crash.

G.Skill RipjawsX, Kingston HyperX Genesis, etc... dont think u can find one in msia yet. I didnt say they are da best, but at least they r certified to pair with Sandy Bridge. Corsair Vangeance is confimed available at local stores. Other compatible rams pls refer to ur mobo manual. Elpida based ram which is extinct in the market might hv compatibility issue with 1155. PSC based is fine.

Well cant really tell u how Vengeance OC. But most likely it is able to do:
1600 7-8-7 or 7-9-7 @1.65v
1800 8-9-8 @ 1.65v
2000 9-9-9 @ 1.65v
Overrvolting is another thing
How to know? Anything mr Google cant help u?

Most prolly 2000 9-10-9 yes but theres always a trick to do 9-9-9 hehe..
Arghh btw i cant simply mix up between one 2GB stick from a kit with another kit it's unstable think one of the reason why couldnt do fine on 4 sticks.

Didnt find any good chip so far. Just that one can post at 56x passing blinking cursor but stuck at logon screen. Dint hear any new stepping from design engineers.
2260MHz - 32mb ?

Maximus B3 will be ready on March 15
Expecting other Asus boards to be the same.

At what speed?

Didnt try that supposely beaten by C7.
But doing great at 2133 7-10-7 @ 1.65v

Could be true, didnt stress that for 24/7 purpose just for Pi is fine.

Finally Streamyx 4Mbps is back to normal after 4 days no signal...

Intel Core i7 2600K 5.0GHz HT ON (4C/8T)
Gigabyte P67A-UD7, F8X
2x2GB G.Skill RipjawsX 2200C7 @ 2133MHz 7-10-7-27-1T
2x MSI GTX580SLI, 930/4100Mhz
Corsair AX1200

134.5w vs 115.8w





Hottest ambient: 35C

thanks for sharing... but i had been getting BSOD 124 frequently since downgrading from 951 to 088. that was on 2nd bios since bios1 was corrupted lol couldn't recover anymore. Now i just wanna swap with B3.

Added on March 1, 2011, 7:56 pmUD7 is good for 5.0GHz and below only.
5.1GHz @ 1.55v bios set LLC2 load @ 1.608v still BSOD 101 (not enuf vcore)
on M4E 5.1GHz @ 1.51v bios set 100% LLC load @ 1.536v stable d.

Just to show LLC is bad on UD7, en route to stabilize 5.0 GHz..

Pi doesnt really stress CPU bro i can pass all 32m without changing ram settings from x50 to x53.
For sure LinX and Prime95 need more vcore, tweaking n settings especially on Win7 SP1
