First impressions with Epox 4PEA

[GreenBeret]

Just got mine an hour ago. Here are my first impressions:

- Green PCB - ewwww
- rev 1.0
- 12V ATX - the previous one, Epox 4G4A, although was a very fast board, didn't have this so it had quite bad voltages.
- 4 phase power
- BIOS and OCing:
Vcore from -0.1 up to + 0.35
Vmem up to 3.2
Vagp up to 2.2 (this is stupid !)
AGP/PCI lock, selectable from 50 to 80MHz AGP.
3:4 divider for 400Mhz FSB CPU and 4:5 for 533MHz CPU.
Usual mem timings.

- Real voltages:

Vcore (stock): 1.488 idle, steady, doesn't move. 1.456 underload, steady, rarely moves. I like that ! The core voltage on the 4G4A and the Asus boards are all over the place.
Vmem (2.6V): 2.656 V real ! Doesn't move at idle. Full load rarely moves. goes down to 2.64 sometimes.
Vagp: 1.52 most of the time, sometimes goes down to 1.504.
+/-5V and +/-12V: stays slightly higher than 5 or 12 at both idle and full load. Almost don't change.

- Performance: no idea I'm on a thrashed OS that has been on 4 Intel boards and about 6 or 7 graphic cards (both NVIDIA and ATI ).

- OC result with 2.4B..........coming soon

What, green PCB ?
This is weird, they have been advertising it with black PCB.

Thanks for the snap shot, let us know when you've developed the picture a bit more ":O}

I love the Vdimm on this board ! 3.2 is so nice ! It overvolts a bit even !

Screw BD7-II's Vdimm.........2.7 max undervolts to 2.65
Screw IT7's Vdimm.........2.8 max stock, 3.2 max after mod BIOS but real max is 3. Still undervolts
Screw P4B533-E's Vdimm..........no Vdimm sensor
Screw 8PE667 Pro's Vdimm.......2.7Vmax in BIOS undervolts to 2.64, no Vdimm sensor

Those are the boards I've recently owned

I had a 4G4A+ before. Wasn't impressed with the Vcore - it was all over the place. so unstable ! This one is just great

I'm mainly testing the RAM atm (cos will sell it soon ). RAM @ 188 2-6-2-2 - Samsung CTL PC2700 in DIMM1. Will go higher soon.

Some Sandra mem comparison at DDR 400....(CTL Samsung, 2.75V)

Epox 4PEA: 2.5-2-2-6

Epox 4G4A+: 2.5-3-3-6

Other boards like BD7-II, IT7, 8PE667 Pro, P4B533-E don't even come close so not worth mentioning ( )

Edit: that is 97 or 98% efficiency.
