Help checking my OC

CPU-Zebra · 27 Aug 2007 at 15:18

I have been Ocing my E6600 for a few days and I'm pretty tired of trying to get it higher. I have it currently at 3.15ghz and I can't be bothered to get it higher for the time being. This is my first OC and I'm just looking to see if there's anything more I can do, or if I really should bother going a bit further on this chip. I got it at 1400mhz FSB, 350 x 9 = 3,150ghz, the Vcore at 1.4V got the memory in sync mode running at half the FSB speed at 700mhz (it's rated 6400 800mhz) and temps only go to about 50 normal 52 when it's hot in my room. I am just wondering if having the RAM at 100mhz less isn't really noticable and cancelled out by the CPU OC? I am just wondering this as if it is worth getting it back up to 800mhz I will try and get the CPU up to 3.4-3.6ghz to get the RAM nearer it's stock speed. I'm going to stress test this now and if it is stable I will keep it like this for now. Thanks for the help some of you gave me with OCing to get here

I'd be very surprised if you couldn't get 3.3-3.4GHz out of that CPU, but you will need to feed it a lot of volts because the Vdroop is so high on that board.

You could also run UNLINKED and just set the RAM to 800MHz, but it seems to give reboot issues with certain BIOSes.

To be honest, you probably have a pretty decent compromise where you are. Battlefield 2142 next?

Well it just froze after about 20 mins on prime95 small FFTs, but I was using the computer quickly going on here to post while the stress test was running could that have caused it to freeze? I have tried running it unlinked to keep my RAM at 800mhz but it didn't seem to want to go over 3ghz like that, unless it was just lacking Vcore. I've put the Vcore up to 1.45 and it shouldn't drop below 1.35 now. CPU-Z is saying the Vcore keeps dropping to 1.213 while idle but speedfan reports it as a steady 1.46V, is CPU-Z wrong? I am going to stress test it again now. I know OCing is a lot of trial and error and testing and the such but I didn't think it would be this much hassle to get my E6600 to just 3ghz stable. Is my board just a bit **** when it comes to steady Vcore? Thanks.

It just doesn't seem to get stable, highest I have had it at was 2.8ghz and it was stable for 2 hours on prime95 before I stopped the test. I just crashed again then while I was just on the internet. It keeps going funny booting up and taking a while etc. It just won't get stable even with 1.45V it wasn't stable just going on the internet, is it this motherboard, because I can't see what else I can do, I've tried linked and unlinked, 1.45 Vcore and even I know that should be enough for it to get to 3ghz stable. Under load is wasn't dropping below 1.4V, and the RAM was under stock speeds.

It's highly unlikely it's the motherboard. A lot of fuss is made about the Vdroop, but it's only actually a hassle because it gives high idle temperatures.

Are you using the +100mV? ie. is the 1.4V you are talking about 1.3V+100mV?

CPU-Zebra · 27 Aug 2007 at 16:35

No but will that really make a difference? Could It not just be 1.4V instead of 1.3V +100MV? Is there something I am missing?

WJA96 · 27 Aug 2007 at 17:50

Yes. As I think I mentioned before, the +100mV can either be fixed on all the time, or set to come on automatically when the CPU is under load (sort of a VDroop fix) but the BIOS sometimes can't actually spot when the CPU is under load quick enough to bring it in, so the machine become unstable.

Try 1.35V+100mV and see if it's stable then.

It just passed 10 hours of prime95 on both vores small FFTs with no errors. It's at 1350 fsb which is 337x9=3.037ghz. It seems stable but for some reason I have a feeling it will still crash while doing easy things like internet browsing etc, which it did before on similar clocks without any stress. (I'm a pessimist

).

Ok, it didn't get angry while on the internet and freeze like before when it seemed stable-ish on small stress tests at a similar clock. But once thing I did notice my RAM was at 9:8 to my CPU, and instead of being 2:1 and instead of being at 675mhz it was at 600mhz. I just checked and it was in sync mode, but I've gone up to 1400mhz FSB and testing whether with the =.100MV works with this.
