Why is this soo lowwwwwwwww?

I just installed this EVGA 780i and fresh windows install

I was hitting 40GFLOPs at 3.4GHz on my old Asus P5K.

What is going on here?

It explains now why I went from P16xxx in Vantage and P65xx in 3DMark 11 to abysmal scores I'm seeing:

P15021 in Vantage and P3717 in 3DMark 11.

Whatttttttttttttttttttt????????

RAM speed and timings set correctly?

Check if all 4 cores are enabled.

God, this is problems which really grinds my gears...
Tried updating the newest 780i BIOS?
EDIT: Ninja'd

Try that and if it doesn't improve performance you could go to the EVGA forum. They are pretty good when it comes to BIOS versions for their boards.
Some Firmwares are worse than the older in some boards.

What was your RAM speed and timings at before? RAM makes a pretty big impact on the GFlops in IBT.

Can you raise your RAM and loosen timings by chance?

RAM and timings were the exact same as it was in my other board, the ASUS P5K. At 800MHz 4-4-4-12 @ 2T.

I was getting like 37GFLOPS at 3.2, 40GFLOPS at 3.4GHz on that board.

Now on my new 780i i'm getting 26/27 GFLOPS at 3.6GHz.

I also couldn't find any BIOS' on EVGA's site.

Thank you.

Also, guess what, I'm 20 passes stable at 3.6GHz
ISO.

I found it easier and faster.

Follow these steps on their website. Painless update.

CD Method (Blank CD and CD Rewritable Drive Required)

* Download the following .iso file: E178_SZ17.iso
* Use a CD Burning software to burn the .iso image onto a blank CD (Nero, Alochol 120%, etc)
* Restart machine, and set the CD Drive as the primary boot device
* The BIOS flash process will begin, Press �Y� to program BIOS
* After flash remove the CD, power off PC Completely
* Turn on the PC and load defaults in BIOS

After reading the OP, I was curious how many GFLOPS my e5400 is putting out on my 780i, and it is also low I believe, about 14 GFLOPS @ 3.6Ghz. Should be more than that at stock speeds I am pretty sure. Maybe there is some type of issue with 780i and IBT? I am worried now as well, and hope you figure this out.

wow thanks so much.

What are the chances it's the BIOS that's causing the low scores.

gonna download the ISO right now.

Thank everyone who's helped so far.

Btw here's the screenie of me passing 20 runs of IBT at 3.6GHz with 1.45v

I have no idea what's causing it.

I went from a P35 chipset to a 780i chipset.

And just when I upgraded to it, it happened.

I was hitting 40GFLOPS at 3.4GHz. Now I should be hitting around 43GFLOPS.

Is my processor junk? is my motherboard to blame? I have no idea.

Fresh install, all settings the same. no idea

Try other stress tests to verify if it is stable. just because it passes one doesnt mean you are stable. Could be that you need to up the NB voltage to maintain stability.
1.45V seems a little high for only a 1GHz increase. As Pio stated before your RAM has a lot to do with it as well. Sounds like an unstable OC to me

=/ I don't think it's unstable. Let me test for 100 Passes. I'll get back to you in a few hours once it passes.

Just so you understand the scaling of this chip:

3.2GHz at 1.2875
3.4GHz at 1.40v
3.6GHz at 1.45v

I could prolly lower the 3.4GHz one, but it makes no difference if it's stable.

I just tried LinX, same GFLOPs, if not lower.
