Voltage settings for an E6600 at 3.6 GHz on a P5W DH

post #1 of 5
Thread Starter 
...what vcore and ram voltage would you use, given my system spec? Also, do you think my spec can handle a 3.6ghz oc?

I just got my WC installed and temp dropped anywhere from 10 to 15C. I tried OC'ing to 3.6, but system just wouldnt boot...I dunno if i had too little vcore and/or ram voltage?

The vcore setting will depend a whole lot on your exact CPU. If it's an earlier model, it may take in the range of 1.5 volts while some of the later weeks will require just a couple of notches above stock. The best thing you can do is gradually increase the OC and up vcore only as needed along the way. You would obviously want to run the lowest vcore necessary to keep the CPU stable.

Assuming you're running your RAM at 1:1, you'll need a pretty hefty OC on the RAM. Stock for that RAM is 338 MHz, and with a 9x multi, you'll be running at 400 MHz to get to 3.6 GHz. Defintely plan on running a few notches above stock vdimm to get there but be sure to stay at or below Corsair's warranty limit. As with the CPU settings, it's best to OC the RAM slowly.

You may also need to tweak some of the motherboard voltages to get to this high of an OC. While 400 MHz is well within the capabilities of this motherboard (each individual motherboard is a bit different, but this model generally tops out around 450 MHz), some care will be needed to get that high.

I'm going to move this thread from the WC forum to the Intel General one as the questions primarily relate to Intel OCing issues.

Oh sorry didn't realize i posted this in the wc forum... meant to post it in the intel one.

I think the primary reason for less successful OC is the RAMs i hvae... they suck I dunno if i should increase the ram voltage to 2.0V+ to accommodate the OC, but the 675 sticks are definitely a burden. I know there has to be a way for me to OC to 3.6 and have the system running stable. My comp HAS booted at 3.6 before, just not too many times. I know my rams can be oc'ed to 400 with the appropriate voltage. I just dn't know what to set it at... i guess trial and error is the only way to go

I tried setting my timing to 4-4-4-12 and system refused to boot. SIGH

Trial and error is the key even though it is often a slow and tedious process. You can always work on your CPU and RAM separately. Set a low divider so the RAM doesn't get stressed much, get your CPU stable at 3.6 GHz, and then work on the RAM. It would not surprise me to see the RAM needing 2.1-2.2 volts, though like I said above, be cautious of the warranty limit if that's important to you (Corsair offers lifetime warranty as long as you don't exceed their voltage limit).

K, that RAM is great for me, for up to 442mhz, which I have in my 2nd rig.......and 2.0v? That's never good for when overclocking. You should use at least a 2.20v.

For the P5W-DH which can do 400fsb on a 1:1, try setting the RAM with a 4-4-4-12 and 2.20v or 2.30v, the Vc should be either 1.55 or 1.60v.

There's a feature in the P5W-DH that you'd need to turn off, it's called: HyperPath 3, disabled it, and this is in the "advance chispet settings"

Also in the section: : "Configure System Frequency/Voltage", there's a couple of things you'd need to do, for example, lock the pci frequencies to 101 and 33.33mhz and also the Performance Mode Set To: should be AUTO.

Finally, in "Advance CPU settings", you should disable C1E and Intel SpeedStep, I think CPU Internal Thermal Control disabled as well.

So, try that. And remember, RAM at 2.20v or even the 2.30v.
