Hey this is my first post on this site and I'm hoping I might get some help with overclocking. I found this thread when researching how to go about this process and wanted to initially post here but the account activation took a few days. Anyway I'm pretty frustrated considering I haven't had any luck posting at sites that have overclock in their web address! So my current build is a few years old and I'm trying to see what reasonable increases I can get which to me is the point right before I have to increase the voltage a few steps just to get one more speed step etc. Mobo - Asrock 780GXE/128m CPU - AMD 7750 BE - lapped, CoolerMaster Hyper 212+ lapped, ShinEtsu NB and SB - lapped, Shin Etsu, NB has CPU stock fan on it, SB has NB heatsink from old ASUS board and case fan blowing across it Case - Rosewill Challenger - fans - 120mm front bottom, 120mm back top, 135mm top rear, added 60mm in 3.5" drive bays to pull air in, 80mm in the lower middle to help direct the front case fan airflow towards the top rear of the case and hit the SB Graphics - Onboard 3200 Ram - OCZ Gold DDR2 800 Hard Drives - ADATA SataII S599 128GB, Maxtor SataII 320GB DVD - LiteOn IDE x2 PSU - CoolMax V-600 Well I've already done a lot of messing around but I could really use some help trying to interpret some of the results and some odd ball situations. I've been isolating what ever I'm working on and then trying to find it's upper and lower limits and any patterns. So far I've done some initial testing with the NB up to 1.45v and I'm now on to the CPU again. I've also tested the Ram and settled on not increasing the speed at this point because I couldn't get it to run correctly so I've resorted to just lower the timings as much as possible at it's rated speed. The ram is currently sitting at 4-4-4-(2-4)-10-15-1T at 2.02v. This was memtested, P95 tested for a few hours, Intel Burn Tested for 5 runs and so far no problems. Now up to this point I've had very consistent results but now that I'm on to the CPU I'm getting weird situations. I've lowered the NB multiplier down between 5 and the stock setting of 9 depending on the base clock I'm using. Then I've lowered the base clock to the lowest of 150 and increased the CPU multiplier to bring me back to the stock 2700Mhz which got through some short tests fine. I worked my way up to 3000Mhz by way of the multiplier and it passed 5 IBT runs yet when I go back into the bios and increase the multiplier a half step to 3075Mhz and hit save, it will reboot but nothing shows on the screen but if I hit the reset button it boots fine and I can test it. The weird thing is that even when this happens and I think maybe it's overclocked too much it will still happen if I go drop the multiplier so the speed is down to even 1500Mhz. Now when I reset the bios and then reapply my basic settings to the memory and drop the NB out of the way and change the CPU to 150 x 20 for 3000 it works fine. If instead of going straight to 3000 I go to 3075 or even 3150 it will boot fine also but if I go to 3000 first and then try to increase the multiplier in half steps it will require me to hit the reset button. What does this indicate? I have tried to narrow it down by changing every bios option to see if it clears up because the bottom line of what is happening is that there is no consistency to when it will boot properly and when it won't even when I know the settings are ones that have worked enough to at least get into windows and pass a few tests. On a different note here are my initial results on the NB: FSB Multi Speed Volts 186 13 2418 1.325 190 13 2470 1.3375 192 13 2496 1.35 226 11 2486 1.3625 194 13 2522 1.3875 210 12 2520 1.4 232 11 2552 1.4125 214 12 2568 1.425 198 13 2574 1.4375 234 11 2574 1.45 I'm not sure if I should push beyond that, the gains are starting to cost more in voltage at this point and I think the Asrock manual online said that the mobo is 2600Mhz FSB which I'm guessing is it's max. Idle temps are around 28 mobo and 30-31 CPU, load has not maxed beyond 41 with IBT and P95 at the same time with CPU at 3000Mhz, NB at 2400Mhz and current memory timings. I have more I could put up but I've already written quite a bit but I'll at least say I've developed a pretty systematic approach thanks to having 2 2'x3' dry erase boards on my wall to keep track of all my testing. My biggest concern right now is figuring out why the computer has a hard time rebooting when I change the settings in the bios even to ones which I know have already gotten me into Windows and passed some testing. Should I just continue to hit the reset button so it will get into Windows and just use my stress testing to let me know if I'm hitting a wall? Any help is GREATLY appreciated:thumbup: Oh I'm using IBT as my initial testing because out of IBT, P95, Orthos, OCCT and Hyper Pi it got my temps the highest at 41 but mostly 40, the others kept it between 36-39.
