Quad Core OC Database

[theYipster]

Hi everyone,

Does anyone have any solid data on G0 Batch L734A?

I have a Q6600 from this batch with a VID of 1.275 that I'd like to get to 3.6ghz on air with a tuniq tower (and perhaps to 4ghz on water later-on.) I have an eVga NF-68-A1 board which successfully ran an E6600 @ 3.6ghz stable (x9 * 400fsb, 1.44 vCore actual) for nearly a year. I tried to get to 3.6ghz with some common settings but ran into trouble.

Over the weekend I'll have to map out this proc's OC capability in a more gradual matter, in hopes that 3.6ghz isn't a stretch. Any information on similar chips would be greatly appreciated.

Mark.

I tested two quads (a Q6600 and a QX6700) on a P35 and an eVGA 680i A1...with both procs, I was stable at up to 3.85GHz on the P35 mobo, but could only get 3.6GHz benchable with the nVidia chipset....I had to drop to about 3.2GHz for full stability.

I mention these results because I don't think you'll be limited by your CPU/CPU stepping...but rather, by your mobo. Good luck!

Here are some folks with results from your week.

Most have a VID value less than your 1.2750v


Here is one ex that can do 3.6GHz on a higher VID

Hope this gives you some confidence.

From what I read, some MB are not Quad friendly you may want to look in that direction.

Thank you kindly for the info Miahallen and Wizard. It's clear that getting this to 3.6 won't be as easy as "dialing in" speeds and voltages (as I did with the E6600 to my satisfaction.) I agree that the motherboard is most likely to put up the biggest fight. After spending a few hours on the eVga forums last night, I do think it's possible, but it'll take a few days of truly mapping out the processor's full capabilities and a lot of trial and error. Btw, the evga is an A1 revision. In fact, one of the two reasons I upgraded now (instead of waiting for the Penryn) is that I can bail out to a 780i board on the cheap if need be (the most expensive components in the rig, for better or worse, limit me to nForce.)

I do have some confidence, though. I under-volted at stock settings last night to figure out if re-seating the heat sink would be worth while (and with a delta of 14 between idle and load, I think it would...) To my surprise, the system is prime stable at 1v (and I still haven't tested for the stable floor yet.) This should at least be encouraging. Perhaps the VID isn't 100% accurate for every chip.

L737B543 ..i suppose iam one of the unlucky with the 1.3125 vid..still manage to 3600 but not prime stable..lower max tempe's need for that..

You think you're unlucky, I have the same L737B batch, but my VID is 1.325, and cannot get 3600 stable, only enough for a superpi suicide post at 3600.
