EVGA 750i FTW Overclock Thread - Page 255

post #2541 of 2885
I've had bad experiences with OCCT. The latest version of prime 95 is still what I use for stability testing. it takes more time than Intel Burn Test (which is useless if your not using a 64-bit system) but if your going for a high overclock like you are, the lower cpu temps produced by P95 "blend" test is what your looking for.

1.45 CPUv is sufficient for some Q6600's, can't say it is for yours though. One way to find out for sure is use the "small ftt" test in prime 95 for 10 hours. I know that sounds like a long time. Its really not though. Increase voltage untill it passes as temps allow.

Try to pass that. then you can worry about your ram and the fact that the last 2 lanes of the GTLref's are broken. they have to be set manually. Testing it right will take a far amount time. Its a good mobo, but it won't set itself up.

One thing you should try though is to set your spp voltage to 1.45-1.5 and see if that stabalizes things. I run mine at 1.55v all the time, but I have a 60mm Rexus topmotor fan on my NB heatsink. NB temps never go over 48c.

I measure temps with Everest Ultimate. Don't know of any other apps that read the temps correctly of the NB on the 750i FTW.

Actually, the 7 series boards can't properly set any of the GTL lanes. Plus with dual-core CPU you really shouldn't have to worry about lanes 2 & 3. Though, some say to set 2 & 3 equal to your 0 & 1 settings. All lanes should be properly tested to ensure you are running the lowest vFSB you can. The board simply fails at auto adjusting the lanes properly for the signals to match up. You should click here.

I was just curious about different memory with this board. I am currently running 2x2 @ 800MHz 5-4-4-15(stock). It will run stable at 900 and default timings, but any higher it is unstable.

I was over at the local compusa and saw a 2x2 kit of 1000MHz ram for like 35$ on a bargin rack. Its OCZ Gold, cas 5 so I am ok with that part and the $.

Just wondering if this board is real touchy at higher ram freq. I know I have read bits and pieces about ram and higher freq so I just figured I would ask before spending un needed $...

As long as you are running only 2 dimms you should be good for ~1100. Boards are not going to run much over that for a 24/7 OC. It has also come to my attention that loosening tRRD can help with high FSBs, mem and QDR frequencies. These board seem to auto tRRD really low (3,4,and 5), try loosening to 10 or 12 if you are having issues with high FSBs.

I've got sad news...I accidentally broke one of the sata connectors on my board and now the board refuses to post. It just starts with the dreaded FF code immediately without going through the post sequence; I tried taking it out of my case and putting it back to make sure that the motherboard was properly grounded but no go. Is it a goner?

The SATA port was the first thing that broke on the 750i FTW for me...

Did it brake compeletly off? If so, take a close look with a magnifiing glass if you have one and make sure that the pins left are not touching each other. If you can seperate them so that non of them are grounding then you should be able to get it working.

carefully solder the piece back on and then RMA it immediately

finally got my setup complete with this board with an e5200 ready to overclock like crazy.
