You have to be gentle with the 975. Unlike the brute 965 that will take anything you throw at it, the 975 doesn't like high voltages, so you need to find the sweetspot where she'll purr for you all day long. Start out at default settings with everything on auto and gradually increase the clocks, you'll be amazed at how fast you'll get on little vcore. Then go manual and fine tune her :) After getting used to the Classy bios, the ASUS bios really sucks cause it wants to do everything for you behind the scenes. Would rather do it myself :)

I agree the classified has alot more options and seems to be the better of the two boards. I have to get the 965 on that board as it did rather well on the R2E however the board seemed to be limited with what it could do. Next LN2 session may be with the 965. Now I just have to RMA the R2E.

I had a similar confusion between the r2e and classified, they are very different beasts!
I'm currently running the nf200 version classified and loving it! it makes you work to find the sweet spots but it deffo rewards you when you do!

keep pushing it , im sure there is much more in that combo.:)

whats the batch# on that CPU
what sort of coolin and CBB & CB did you experience?

what got you past 170MHz bus speed in the end?

I will have to get the batch when I get home I spend from Sunday bight until Friday on the road with work. I can tell you I've had the CPU at 200clk however I need to play more to get any type of stability out of it. This was also on air with the intel stock cooler. I had the uncore at the lowest setting and QPI set to 4.8 setting under CPU feature.
I have yet to figure out the CB and CBB temps. This weekend it wouldboot at -95 then I would try and reboot at -75 and CBB. Heat gun to the pot bring the temp down to -68 she would boot. Reboot at -90c and it would boot. I have yet to get this CPU beyond -100C so I am unsure where the CB is.
I will test out the CB next time I have it on LN2.

I'm curious, what exactly is your RE2 doing? The Classified is great but I wanna try another board, I was thinking RE2.

When I press the power button the fans spin up and the LCD poster goes right to the time and no boot. Thiis is with both the 975 and 965 processor. I will be calling Asus Friday to set uoan RMA.

good results mate, your doing well... i find the classified a sharp learning curve also, but once you work out what works and what doesnt it is a very powerful and strong board

Just put mine up for sale today over at our site - $275 for a version 2 :) Have manuals written in Chinese and English lol

I started with a 965 on the R2E on water and the sucker screamed for me. I was posting amazing speeds at what everyone was telling me was low voltages ?? Then I got a Classy (758 w/NF200) and put it on phase with the 965. Definately was a learning curve but once I learned it I fell in love. With the 965 all you have to do is throw volts at it and it says "great, let's go faster" lol Then I got a 975 and put it on the classy under phase... it went faster, and scored higher even at the same speeds, but throw volts at it and it says "hey, what the frack you think you're doing??? turn that stuff down"

Been using the R2E with a D0 920 as a gamer, but can't get warm and cozy with a locked proc, so I decided to sell the board and bought a new Hydro copper classy to use as the gamer. Not sure if I'll sell the 965 or the 920 at this point though :Dizzy:
