gagrin77 Posted January 28, 2015 Share Posted January 28, 2015 Forgot to add that I had two of those X5460 that were going even near 5GHz but due to insufficient cooling I wasn't able to access OS and provide cpu-z validation. I have made a picture of in-BIOS cpu configuration page. Quote Link to comment Share on other sites More sharing options...
Xevi Posted January 29, 2015 Share Posted January 29, 2015 Use: 1:1, 1 or 2 cores, 1.6vcore, SetFSB code: ICS9LPRS918BKL Powodzenia Quote Link to comment Share on other sites More sharing options...
ludek Posted January 29, 2015 Share Posted January 29, 2015 (edited) Nice motherboard and CPU there ..LPRS918 is the same or similar, as in P5E3 Premium and P5E3 Deluxe and P5E64 WS Evolution BTW. Gagarin if you want, please join our team http://hwbot.org/team/overclock.pl_team/'>http://hwbot.org/team/overclock.pl_team/ (http://hwbot.org/team/overclock.pl_team/) and look at ours forum http://overclock.pl/forum/forum.php'>http://overclock.pl/forum/forum.php (http://overclock.pl/forum/forum.php) Keep pushing!

gagrin77 Posted January 30, 2015 Author Share Posted January 30, 2015 Use: 1:1, 1 or 2 cores, 1.6vcore, SetFSB code: ICS9LPRS918BKLPowodzenia  1:1 is more unstable. After a lot of tests I concluded that this motherboard with high FSB prefers second to last option of RAM frequency (last and highest option is 1:1) at 400 strap. Next in hierarchy are some options from strap 333 and after that is 1:1 on strap 400. But I will try and see what happens if I use SetFSB with 1:1.  BTW I have no idea why cpu-z and MemSet and Aida64 reported 1650MHz, BIOS setting was around 1520 or something like that.  I have c2d E4500 as my backup LGA775 because on one occasion motherboard recovered with previous BIOS version (without microcodes) and than it automatically reflashed even older one and so on with every reboot until c2d saved the day. Next week I will have a celeron 440 and I'm going to kill it Quote Link to comment Share on other sites More sharing options...
ludek Posted January 30, 2015 Share Posted January 30, 2015 There was a bug in P35/P45/X38/X48 chipsets. If you set ratio (FSB:MEM) 3:5 than it's really 2:3. Maybe this is the main reason. 1:1 on DDR2 motherboards is the most stable. On DDR3 it's little more complicated. It's all about keeping mems at just stable settings. For example FSB 500, 2:3 CL7 or 8 with my Micron D9 Mems is more than stable. 1:2 or 2:3 is also stable but it depends on your mems (so the voltages and timmings). Strap 266 for 2:3 is the best on X48 Asus I think. I don't know how it's working on P45, but think it's similar. Quote Link to comment Share on other sites More sharing options...
ObscureParadox_3XS Posted January 31, 2015 Share Posted January 31, 2015 btw a 4GB module is also more stress on the NB. Have you got a 1GB or 2GB module to put in there? Quote Link to comment Share on other sites More sharing options...
gagrin77 Posted January 31, 2015 Author Share Posted January 31, 2015 @ObscureParadox yeah, I know those P45 boards don't like 4GB modules. I would very much like to see what happens on some old 1GB performance stick that can handle higher voltage, but I don't have any. At top of that the limits on BIOS timings settings doesn't give much space - Gigabyte EP45T has much higher... and even than it still has problems related to RAM.
