Arrow Overclocking Intel Core 2 Duo E6600 2.4GHz/1066

Okay, I've been trying to read around in here about overclocking this CPU. From what I can tell, I should be able to just up the FSB to at least 3.0GHz/3.2GHz. My question is this, do I need to change anything else?

My current idle temps at 2.4GHz (stock) with Tuniq Tower 120 (fan at 1700rpm/60%) are 27'/23' C.

I'd like 3.0GHz, at least. Thanks.

You'll need to up your vCore and maybe your RAM voltage if you OC it. 3.2-3.4Ghz shouldn't be a problem. Set others to auto unless you hit problems.

On my P35 board I upped the fsb til it was just barely unstable, then backed off a bit. Left all voltages at default and had a good strong 3ghz OC. This was with an E4600 which is 2.4 stock.

Like Revs said though, start bumping vcore and vdimm if you want to shoot higher.

I left the voltage the same. Adjust the ram so they won't go over their rated speed and increase the FSB to 333. Lock the PCIe clock to 100 and the PCI clock to 33. You have 3.0ghz easy. I don't go any more, I prefer overclocking that is nowhere near the limit of the CPU and always on stock voltage. I also never overclock the memory... Disable any spectrum relevant entries you see, C1E, Speedstep. Also, put your ram timings manually (ie 5-5-5-18).

1.5 vCore and 60.1*C are the limits for that CPU

FSB termination and north bridge voltage could also be considered.

With my old Xeon 3060 (Conroe 2.4GHz - same as E6600) I was able to easily get it to 3.2GHz. I dropped the multiplier down to 8, increased FSB to 400. It was stable at 1.375V. My temps never went over 40-45C, however, I am on water.

Thumbs up Re: Overclocking Intel Core 2 Duo E6600 2.4GHz/1066

So far, so good!



I do have some questions about Advanced Timing Control. I don't know if I need to change any of them and even if I do, I don't know what to change. The settings are as follows;

ACT to ACT Delay (tRRD) 4 [Auto]
Rank Write To Read DELAY 4 [Auto]
Write To Precharge DELAY 8 [Auto]
Refresh to ACT Delay 56 [Auto]
Read to Precharge Delay 4 [Auto]
Static tRead Value 4 [Auto]
Static tRead Phase Adjust 0 [Auto]

i was able to get to 3.2 on stock cooling. my chip runs about 36 degrees on the cpu 44 degrees on both cores idle . you should be able to get another 200mhz out of your chip easy.

356 mhz x 9 multiplier
1.35vcore

Yeah, for some reason I haven't had much luck with 3.2GHz, but I may toy with it some more. I'm 100% stable at 3.0GHz, but for some reason CPUz is showing my voltage at 1.312, which is weird, because in the BIOS I have it set at 1.35v. I better have a look, again...

Hey dude. My E6600 OC'd better with an 8x multiplier. Also the higher FSB will make your memory bandwidth.... wider

Weird, man, because I was thinking about going to an 8x multi when I tried for 3.2GHz or higher. LOL

Okay, I bumped the voltage in the BIOS to 1.375 and now CPUz shows this;
