It's early days and im not done yet. Having now spent a lot of time on it though im dying to play some games. Got my 1300W psu in now and just reinstalled windows, so will play some games for a bit then get right back on it.
Games are for kids!!!

Ta, was getting 01 at board defaults!! Think i've screwed the bios again as ive lost a ram channel again, remedied this last time with a bios flashback.
Tried shammy's 2400 cas 7 profile but the sticks didn't like it, can go to 2500 cas8
Would there be anything to slacken to achieve 2400@cl7??

I'm a gamer first mate, but i still like a bit of benching in between.
Thanks for your guide, really helped. Think I'm almost done now, will post my timings soon to get your final seal of approval.
What's your opinion on using the straps 8pack? Better to use them or leave BCLK at 100? If so, any specific recommended settings?
Soldato

On sandy e I found 125strap enabled me too push higher clocks at a lower voltage usually around the 128.5-130 Bclk range any higher and it started to effect max gpu core speed, you should be able to gain another 50-100hz on your comfortable max voltage. With ivy-e I'm finding not much difference between the 2 straps.
For gaming I just leave it at a flat 100.

Thanks Nick. That's interesting so 125 strap could = lower core voltage on my cpu? That would be nice as my chip has a high VID.
Soldato
Yes it could but as 8Pack says in his guide you need to running around 129-131 bclk which helps with modulation, but on my cards going above 130 affects them(lowers max clock) but there all different so you have to test yours. Say your max at a flat bclk is 1300mhz you may only manage 1280mhz but as the bus speed has increased this kinda offsets that so you will score around the same, sometimes higher. You just gotta find the right balance.
You could test by running 100bclk, 2400 ram, and your max gpu clocks, run bench and note score, all 3 if running say FSX
Then switch to 125 and ram to 2333 and up bclk till ram is at 2400, which I think is around 128.75, then test gpu's and try and get your max, run bench and compare.
May need a bump to VTT and SA to help.
Work on vcore after if your happy with results, and as in the guide experiment with PLL volts 1.6-1.7v

130BCLK has been the turning point for me also with both my three Ti and Titans. Also as Nick suggests lower PLL can help reduce vcore a notch or two
You know that's what GPUs are for right mate? You spend a fortune flying across the globe making a name for yourself in the name of kids

Cheers guys. I will work on BCLK once I've got my 100 BCLK overclocks sorted. Having to retest my memory timings again as i found dram write to read delay of 4 was causing stability issues. Set it to 5 and so far so good, now reapplying my thirds.
Caporegime
Nice timings mattis that at 2133??? Have you tried cas8??
Sorry Nick missed your post on the page change.
Ram is at 2400Mhz.

Why do you think my VID is lower than yours lol try those settings I posted,
After reading the guide and asking 8pack my chip deffo preffers strap clocking
only thing is strap clocking alter ram speeds my 2400mhz actually run at 2407mhz
Caporegime
get your strap on matt

Testing out a 4.8ghz overclock with the memory timings and speed used for my 4.5ghz overclock. Yikes i need 1.456v.

ha ha just were i'm at with voltage!! apart from yours will be safer than mine, can you run firestrike(normal) i wanna see your physics?? i'm only running dual channel so wanna compare, ignore overall/gfx as there @ stock, not sure what its gonna do when i clock em up!!
Caporegime
Wil do Nick if i can get it stable enough. These are just benchmark runs so im not going for complete stability but im not even close yet. Now experimenting with the strap.
Soldato
cheers bud
appears dual channel is working well, my highest yet, still need to wire up 2nd psu so i can unleash em!!
Caporegime
Nice one. Is that fully stable, or just bench stable?
Soldato
bench stable, i can run 4.8 @ 1.41v which is fully stable but no need for 24/7
Caporegime
I'm up to 1.472v so far testing stability on 4.8. Don't think ill be going much higher with this one. Maybe 4.9 for quick bench runs.
Caporegime
Almost fully stable at 4.8ghz. 1.464v-1.480v. This is probably the maximum i will go while stress testing and will just hope and pray i make it through benchmarking tests at 4.9ghz.
