E6600 - Happy with low volts.

GRiDlock · 23 Jan 2007 at 08:17

My E6600 is 100% stable at 400x8 3.2Ghz with only 1.225v, but even if i give it 1.45v it will not go much 3.3Ghz. The same DS3 and Geil 6400 have run a E6300 @ 500x7 3.5Ghz (but not 100% stable).

Anyone else getting good undervolting overclocking ?

Hi, is that BIOS set vCore?

GRiDlock · 23 Jan 2007 at 08:52

Yes, The default for the CPU appears to be 1.265v. Bios vCore set to 1.225v and EIST switch off.

thats interesting, it appears that there is quite a difference between the stock volts of the e6300/e6400/e6700? (my e6300 says 1.35vCore on the box).

I've not seen this broad-range of stock voltages before (well not to this degree anyway) I'm beginning to suspect that the e6600 and higher cpus are a 'purer' wafer in more ways then one . . .

Thats interesting, as the stock voltage on my 6400 is 1.325v!

Not had chance to do any overclocking yet, other things to do atm

Is that what it says on the box or?

Arthalen · 23 Jan 2007 at 10:08

Nope, thats the Vcore set to 'default' under Bios. Then below it reads 1.325 as current CPU voltage.

I believe it may be different in windows with CPU-z, but doesn't that still have issues with reading voltages correclty ?

Is it getting too hot, maybe? What are the temps?

Using TAT : Orthos loaded temps are about 55c and idle temps around 42c (using Zalman 9500). Temps get to about 62c when running 1.45v 3.4Ghz (not stable).

My e6600 box says "max 1.35v" i run it with 1.225v in bios (cpu-z shows 1.192v) at 3.2ghz (9x356) stays really cool dual orthos is around 38 degrees

Using TAT ? 38c loaded is very impressive.

JeffyB · 23 Jan 2007 at 11:32

Yes i use TAT, and thats with my tuniqs fan on low/med speed

JeffyB · 23 Jan 2007 at 11:47

Heres temps with a quick run of orthos priority 9, cpu-s showing 1.176v which is lower than usual as well.

Van Diemen · 23 Jan 2007 at 12:02

I had an E6000 @ 3.0 (333x9), 1.225vCore 100% stable

I am using CrystalCPUID to lower the voltage as my motherboard won't allow voltages lower than stock. While that is only a quick run of Orthos it seems perfectly stable running multiple programs (PS, games, video conversion etc.).

I am using a freezer 7 pro with an 850rpm 120mm fan, I decided to test undervolting as I plan to upgrade to a Scythe Ninja or similar and run it passively. Voltage was set to 1.2 however it appears to undervolt a little. Either that or CPU-z still can't read the voltage correctly.
