I've been working the HTT up in 5mhz intervals with the ram at stock timings of 3 4 4 8 @ 2.8V and finding the exact vcore I need for a stable system at each setting.

I got to 225x12 (2.7ghz) with the vcore at 1.7V and the system stable but when I tried 230x12 it wouldn't even pass OCCT.

So I dropped the multi to 11 and worked up to 235x11 (2.59ghz) with no problem but when I tried 240x11 (2.64ghz) even at a vcore of 1.7V the compter wont boot into windows.

Once again I dropped the multi to 10 (2.4ghz) - can't get into windows.
Then 9 (2.16ghz) - can't get into windows.
Then set the ram on the 2/3 divider - still no luck.

I'm stumped but think either the CPU is just not up to it or I need a better PSU. I currently have an X-Pro 460W.

Any ideas?
 
I think you're talking about the LDT/FSB frequency ratio?

It's already set at x3 i.e. 235x3x2=1410mhz.

Stock for my chip is 1600mhz but anywhere between 1200 and 1800 should be okay but I'll try changing it anyway just to be sure.

Also the computer remain stable at 2.7ghz at any less than 1.7V. I've ran prime at all sorts of voltages to confirm this.
EDIT: It will boot at 2.7ghz @ 1.6V but is unstable until 1.7V.

Socket 754.

Reviews of the ram say it's good for around 280-285mhz at stock timings.

It boots until the windows loading screen then just resets. No error messages or anything.

240x10 is stock for my CPU and it's way below stock for the ram so I don't understand why it wont work.
 
Problem solved. A guy on the DFI forums helped me out.

Turns out that SATA ports 1 and 2 max out at 235mhz so I had to move the drive onto SATA 3 or 4.

Now running 240*11 no probs.
 
Up to 260mhz with the ram already. I'd settle for 270 or 275 with a 10 times multi.

Until my new case and water cooling arrives at least. ;)
