pervertfreak Posted February 1, 2005 Posted February 1, 2005 I've been running my P4 3.0C overclocked to 3.5Ghz for months and it seems very stable but after reading that some people with my same CPU and mobo were reaching as high as 3.7, I decided to attempt 3.6Ghz. I've got an Asus P4C800-E Deluxe mobo with Kingston Hyper-X DDR500 ram which I know can handle it, so I think it would be entirely up to the processor whether it would be stable or not. So I overclocked to 3.6Ghz and ran PCMark04. It passed with no problems and gave me an awesome score. Then I ran AquaMark3 and it passed with no problems and it too gave me an awesome score. But when I tried 3DMark05, it crashed and rebooted. I tried it twice and it crashed both times ) : What do you think I should try? Should I up the voltage a little more? I'm presently at 1.6-1.625V. FYI - My P4 multiplier is locked at 15 so for 3.6Ghz, I'm at 240FSB X 15 = 3600 THANKS! My first post! WOO HOO! Quote Share this post Link to post Share on other sites More sharing options...
GregP24 Posted February 1, 2005 Posted February 1, 2005 Up it to 1.65v. Don't go over 1.7v unless you are watercooled. Quote Share this post Link to post Share on other sites More sharing options...

BabyBalrog Posted February 2, 2005 Posted February 2, 2005 Up the AGP voltage to max and give teh Nothbridge a little boost, You Vcore looks fine it's probably elsewear liek Vdimm Quote Share this post Link to post Share on other sites More sharing options...
pervertfreak Posted February 4, 2005 Posted February 4, 2005 Well, I upped the voltage to 1.65 and this time it didn't even make it into 3DMark05. It would crash immediately as soon as I tried to open it. Screw it, I'll just have to be happy at 3.5Ghz. Quote Share this post Link to post Share on other sites More sharing options...
HoLoDreaM Posted February 4, 2005 Posted February 4, 2005 Up the AGP voltage to max and give teh Nothbridge a little boost, You Vcore looks fine it's probably elsewear liek Vdimm 410099[/snapback] if its 3dmark... it could possibly be an AGP issue or whatnot like he said.. try that Quote Share this post Link to post Share on other sites More sharing options...
Cyberbeer Posted February 4, 2005 Posted February 4, 2005 Did you lock the AGP/PCI bus at 66/33? If not try that. I've also noticed with some Asus boards they dont like the 1.625-1.650 Vcore range try upping to the next but I wouldnt go over 1.7 unless you have awesome cooling.

anthony Posted February 4, 2005 Posted February 4, 2005 Its your motherboard's fault. the ASUS p4p800 series has droop problems, I too cant make it past 3.6 Quote Share this post Link to post Share on other sites More sharing options...
Cyberbeer Posted February 4, 2005 Posted February 4, 2005 I made it past 3.6, and I think with better RAM I could make it past 3.8, I'm aiming for 4.0. Though I may buy another mobo to make it that high. Quote Share this post Link to post Share on other sites More sharing options...
biggallo55 Posted February 5, 2005 Posted February 5, 2005 I had the same problem your having. I have come to find out that if i even give the ram the slightest amount of voltage higher than its recomended it will be unstable immediately. I say that because i was struggling to hit 3.6 stable for a long time. and according to everyone i should have hit it easily. the reason i didnt is because the voltage and timings to the ram were not at its specs. for hyperx im saying. i would recommend that you set the ram voltage to its recommended and its timings. and from my experience, i upped the cpu vcore to 1.7. although many would say that is high i found it most stable at this settings. maybe my info might help.

davidst Posted February 5, 2005 Posted February 5, 2005 make sure you have, if it's availble "spread spectrum" disabled in cmos Quote Share this post Link to post Share on other sites More sharing options...
ICON57 Posted February 5, 2005 Posted February 5, 2005 just wondering...before you tried to up your oc, were you prime95 stable? And have you run memtest? Quote Share this post Link to post Share on other sites More sharing options...
