I used to have an e6550 overclocked to 3.4ghz. Then I got a 4870, and it was only stable at about 3.3Ghz.
So I decided to buy an e7200 and sell my e6550, because I've seen that most people can get them to around 4Ghz. I also ordered 2 gigs of ram to go with the ram I already had.
I got everything today, and put it all together. I started overclocking, and the most I can do is 3.4Ghz, regardless of voltage. I went up to 1.4 volts, and the ram was at 2.2 volts, even though it wasn't even overclocked.
I was hoping to get to about 4.2Ghz, because I have a good cooler and a case with good airflow.
I was just wondering if this could be a power issue. Like maybe my power supply isn't enough.
I don't think this would be the case, because things aren't under load when it's first starting up. (it always crashes when vista is loading when I go past 3.4Ghz.) Can a not so good power supply limit an overclock?
Motherboard: Gigabyte GA-P35-DS3R
Memory: GeIL and A-DATA 800mhz
Cooling: Tuniq Tower and Antec 900
PSU: Rosewill 550 watt
I know that the RAM isn't exactly the same, but they can both do at least 900mhz at 2.3 volts (what I used to run my ram at) and 900 is more than enough for what I need. I didn't get the same exact ram because newegg didn't sell the ram I originally had anymore.
And I know the PSU isn't really the best brand, but it is pretty decent and has good amps.
I'm confused, because before with my e6550, I had it at 486 fsb for a speed of 3.4Ghz. The ram was running at 972Mhz. So I know my motherboard can handle the speed, and I know my ram can handle the speed. And although I haven't tried the new ram at high frequencies, they do work fine at 900 mhz at 2.2 volts. (A-DATA is the new ram)
So in the bios, I disable all the speedstep stuff, and I put the fsb at 379, with the ram at 758. Multiplier is at 9.5 so this is 3.6Ghz. I figure 1.35 volts should be enough for this. When I start it up, it starts to load, and then it either restarts, or a blue screen flashes for a tenth of a second and then restarts. The ram and the motherboard are both well within what they are capable of, and I have even tried upping the voltage on the processor up to 1.425. I just can't get it above 3.4Ghz, and I'm thinking it's a power issue, but I also think my power supply is fairly good. The only reason I think it might be the PSU is because I had to back down a little bit on the e6550 after I got my 4870.
When I go to 3.4Ghz, I set the fsb to 358, ram on a divider so it's at 790, and voltage is 1.3.
I've also tried getting to 3.6Ghz with different multipliers, like going 400mhz with a multiplier of nine, and ram at 1:1. Still doesn't work.
Oh, and also, when it restarts, it doesn't reset my overclocking settings, so it doesn't seem like it's unstable, is seems more like there's something else wrong.
And also, the temps are pretty good. Idle is 40(which is actually a little worrisome, my e6550 idled at 30 or so) but after a few minutes of stress testing it only gets to about 58, and I just want to stay under 70. So I have room there, and this is with all case fans on low and tuniq tower on lowest setting.
I read on some forum somewhere that this guy had trouble overclocking until he did the pin mod, that takes it up to 333 fsb. Then he could overclock it further. Could this also help me? I'm sure I'll try it eventually, if nothing else works.
I already have the most recent bios.
Sorry for it being so disorganized, I copied a few posts from another forum into this one, so it's a little jumbled.
Thanks everyone for your help.
