Ideal mobo for E8400 (in 2009) - Page 2

30th April 2009, 23:38

(I apologise for blabbing too much...)

I've done some research and narrowed everything down to:

Code:

ASUS P5Q-E - £120.86

GIGABYTE  GA-EP45-UD3R - £121.09

As I said, I would like to try 8*500. Does anyone have any experience with any of these two?

I went and got the ASUS, which I think it is better because it offers additional BIOS options, which allow it to consistently hit higher OCs than the Gigabyte one. I am talking about the GTL options, as per this thread.

I will be posting OC results this weekend.

either one should do fine; P45 based motherboards with OC friendly bios tend to scale nicely towards 500, or higher

The ASUS P5Q-E is freakin' awesome

I don't know if the Gigabyte is/could be just as good but from the reviews I found online it couldn't do this:

or this...

What you see as 'Performance Level' in MemSet, is the infamous tRD timing. In the ASUS BIOS is under 'Ai transaction Booster', labelled as 'Common Performance Level'.
(I don't know why they couldn't just leave it as tRD...)

nice results

Secret of P45 is to run the rams on a divider... 600FSB is doable on both boards for benching...UD3P is the best benching mobo

I ran 500FSB too with 1200mhz on the rams...

Do NOt run auto voltages on the Asus boards plz. They seriously overvolt (PLL and FSB Term go crazy with AUTO) Also NB is best kept under 1.35 for daily use, as it's stability is very heat sensitive....

Can you check with CPU-Z (mainboard tab) which version of the P45 you got mate ? Asus boards were all Rev 1's , Giga was Rev 2

Sure...

Not to worry, my vNB is 1.18

I was hoping to try 1:1 at 600. Do you think it'd be possible?

For a benching session yes, 24/7 absolutely a no. But you will need to tweak the Skews and GTL's to get pi 32m stability. For just a screenie it's easy, stability that's something else. I went slowly 580-590-595 and finally 600FSB

This was at 4.2, I tried it due to that bad CPU

( EIST enabled )

No, I won't bother then. I want something I can run 3D games on.

Can you give us an Everest RAM bandwidth screenie?

That is a lot of voltage on the CPU. Water-cooling?

Your BIOS is rather old. Any reason?

I had a few P5Q dlx's mate and last bios I used was 15xx series. Newer bios isn't always better as we had very good results with 8 series biosses.

That CPU needed for 4Ghz (8x 500) 1.45Vcore to be stable. Once you start pushing FSB you need to give the CPU more vcore too for the same final clockspeed. Same for my Qx9650 for 4ghz ops ( 445 x 9 ) I needed 1.26Vcore, for 8 x 500 1.36Vcore.
