So no way to pass 315mhz fsb on that board..

I see better efficiency then mine here, very strange my rig score 200 less points with the same hardware

I can see now, my Memory window is covered by "save" window. Here are all the settings: http://hwbot.org/submission/2522506 . I have dual channel mems 6-4-4-5, good memory memset tunning and slim windows (39 MB ram idle without explorer.exe) You should try better windows tunning RTM875 has only three FSB changing legs. All combinations are 133/166/200 (others are reserved) so no way to set 266 which probably would work better. Try to find better motherboard. Had lots of fun while OCing, tunning and benching

good job

[Mat_Agnesi]

Yes, the windows I've used is uncleaned, has a lot of software installed. Clean Windows and Dual channel seems to make a good difference, but better than that, the bigger bifference is made if you find a PM45 chipset mainboard. At same clock, It seems to score a lot more if compared with our PM965 board. I have a GM45 board now, don't know if it's good as the PM45 or not, but seems to have far better efficiency if compared to pm965. However I can't mod this board now, because it's not mine

I have an Intel Q965 based mobo and it seems to be a little slower than P965 at the same frequencies. Maybe the difference between GM45 and PM45 is the same thing. I'm not going to buy other motherboard. What vCore and vNB did you used? (BTW I still do not know, why my Elpida mems are running at those timings )

 

Thanks

For vCore, I've used only a little overvolt over default, not need for more volt.

For vNB, if I remember well I've used near 1,27v. Elpida mems ?? I've tried 3 different RAMs, (Samsung, elpida) and the better for overclocking proven to be the Elpida !! My Elpida 1GB DDR2 Bank can go up to an incredible 500Mhz 6-7-7 timings. But performance seems better at 420MHz with tight timings. Unfortunately I have only one Elpida RAM, so I cannot use Dual Channel.

Do you have use pin mod or do you have have change fsb frequency by software?

[ludek]

As I wrote above:

Lots of mods here vNB, vCore, cooling mounting, swich_ON, TME mod, bsel, SPD mod (SPD tool).

 

 

Sadly, this clock generator has a wall at 315 MHz, no way to pass... RTM875T-606.

 

I was using setfsb with this:
