snikx Posted September 5, 2006 Share Posted September 5, 2006 HI, I own a P5LD2-VM mobo with i945G and a core2duo E6300. Everything is working fine on tiger as everything is recognized. However, i can't get more than 285Mz of FSB without having black bios scren... I tried different voltages and setup, but i can't do more than 285Mhz. I know this chipset is not known for his overclocking capabilities but i need your feedback about successful overcloclking with this chipset/board. I wonder if disabling internal GMA950 chipset in the bios and having a PCI-E graphic card instead can do better overclocking ? (I presume northbridge only is less stressfull than northbridge+graphics, so more fsb could be achieved?) Feel free to give your experience/ideas.

Guest bikedude880 Posted September 5, 2006 Share Posted September 5, 2006 As I have successfully OC'd this mobo, I will tell you that it is not the best for this, though it is possible. Obviously you know where to OC on this board, so: NOTE: THIS IS FOR MY RIG. YOURS WILL BE DIFFERENT. 1) Go to that location in the BIOS. 2) Set it to manual. 3) Set the PCI-E frequency to ~116-118 CPU freq. to ~165 PCI Clock to 33.3Mhz Memory Voltage to 1.904 (or lower) CPU Vcore to 1.3375 or AUTO 4) I am not responsible for what you do to your CPU and mobo. A rule of thumb when it comes to OCing, small increments and be careful. And finnaly, Good luck! Link to comment Share on other sites More sharing options...
snikx Posted September 5, 2006 Author Share Posted September 5, 2006 Thanks for your setup. However, i think PentiumD and core2duo are different to oc'ed (FSB is 1066 on core2duo, so at 285Mhz FSB=1140Mhz) , so i think i reached the limit ! The parameters you gave were very closed to mine... Do you try without GMA950 enabled ? (with external PCI-E card) Other question : I see you have dual HDD, do you try soft raid partition in OSX ? (not as boot device i read it's not working, but as extra partition) Link to comment Share on other sites More sharing options...
Guest bikedude880 Posted September 6, 2006 Share Posted September 6, 2006 I have not tried using another graphics card as I am too cheap to buy one for a budget computer. As for trying to do soft-raid under OS X, that would be another no. I use one HD for testing, and the other solely for OS X. As a matter of fact, right now the only thing being booted on this computer, happens to be the only OS on the thing. Link to comment Share on other sites More sharing options...

KJY9 Posted September 16, 2006 Share Posted September 16, 2006 Anyone has tried ? In your bios you have the option to lock down your PCI-E and your PCI bus speed, this will have no effect on your OC one way or the other. Link to comment Share on other sites More sharing options...
aberracus Posted September 18, 2006 Share Posted September 18, 2006 i have the Gigabyte ga-945p-s3 a 945p chipset, and right now im overclocking my 6400 to 6600 speed, look: my FSB is now 325 my PCIe is now 110 ram is 2x ram timing are 4,4,4,12 my mobo could go for 350 or more but the pcie didnt, i suspect my videocard cant whistand more than 111 or so speed. temperature under osx idle are: Core 1 34 degrees C Core 2 33 degrees C HD 30 degrees C During xbench Core 1 went to 46C and Core 2 to 40C My xbench results and more details are on my sig. cheers Aberracus Link to comment Share on other sites More sharing options...
Wallstreet Posted October 1, 2006 Share Posted October 1, 2006 I've got a P5LD2-VM 2.0 with an E6600 - My results and some info that might be helpful to you are here: http://forum.insanelymac.com/index.php?sho...c=28915&hl= Good luck! Link to comment Share on other sites More sharing options...
ChuckDSanders Posted October 29, 2006 Share Posted October 29, 2006 Hey man. It depends on how fast you want to over clock your computer. The e6300s are like 1.83ghz so thats 266*7 multiplier. Now from what I understand you can't move your multiplier unless you have an EE chip. So that means you need to OC the FSB. Those chips are crazy as far as how far you can pus the FSB. Now it more depends on the quality of ram and quality of the motherboard in conjunction with how cool you can keep the whole beast at. Now your chip as a slight advantage over the 4mb conroe chips. It has 2mb so juice to push it higher. Check what the safe voltages are on the Intel OC boards because I don't know. I have an OCed to hell 830D Smithfield chip and my chip OCed is only about as fast as yours stock. Another key thing is having a decent power supply. Something nice and dual rail should do. Hope this helped a bit and hope you have fun OCing your lil hot rod. PS the Zalman 9500&9700 are great HSFs and anything on www.fronzencpu.com is awesome pretty much. And don't push your PCI clock to 110. only Do good multiples if you can. What you are trying to do is get all the bottle necks out. If you push your FSB so high but don't compensate by tweaking the rest of the system your North bridge will geek out because of all over the routing fun Link to comment Share on other sites More sharing options...
