Starting with CPU and Memory support, the P5E3 supports all current LGA775 Intel chips along with the most recent 1600FSB 45nm parts. However, while the X48 chipset only natively supports DDR3-1600 memory, Asus have ramped up the unofficial support on the board to DDR3-2000 (memory permitting of course).
Next up on the list is Asus' "little bit for the environment" - the Energy Processing Unit (or EPU for short). The EPU is an onboard, hardware-based power saving IC controller that digitally monitors and fine tunes your CPU's power supply in real-time, providing improved VRM efficiency under light and heavy loads. According to Asus, this can provide up to 58.6% CPU power savings - but only when Intel's on-chip energy saving "C1E" technology is disabled.
Just like on the previously reviewed P5E3 Deluxe, the P5E3 Premium also supports the latest 802.11n WiFi technology while also keeping backward compatibility for the older (and more widely used) 802.11g standard. Asus have also included two WiFi antenna's in the box -but we'll get on to that over the next few pages.Most Recent Comments
yeah, thats pretty good as my x38 gets real toasty, i guess thats what aids overclocking the fact it runs cooler, as 680i boards were awful with stock but under water really rocked most of the time..
Nice review btw :) i look forward to a proper read later
It does certainly help, and even with the stock Asus aluminium heatsinks/copper heatpipes I didn't find that the NB got hot in the slightest.
Apparently the 790i is a lot cooler than the 680/708i (according to the marketing dudes), but I'll be able to say for sure in a week or so :)
Are OC3D getting one in? theyve been on show on cebit, which i spotted one in a hexus article, it looks like a heatsink about the same size as that on 780i, but hopefully your right and it is a lot cooler.
I've got one here at the moment. Been playing with it for a while but can't say anything really until the 18th when NDA is lifted :(
It IS better than the 780i tho....
i'm guessing you've got the review done, and will post it at 00:01 on the 18'th? :p
Great review once again Jim.
I am sorely tempted to get one of these. Either the P5E3 or the DFI x48lt...hmmmm.
Don't ask me to choose. I'm a sucker for lush motherboards. The P5E3 does have the edge of BIOS options/voltages tho...i'll give it that for sure!
For all you LN2 Junkies out there!


performs well
asus have been listening to people and implimenting some good ideas into their motherboards it seems...
