4.8 at 1.18?

that don't seem right

It's 1.4 from the central software suite, the CPUID software is obviously misreporting it.

CPU-Z 1.58 was released today. And has fixed some issues for some of us. Might be worth taking a look at it.

is anyone else seeing quite a big voltage increase needed between 4.2 and 4.4?

1.232 for 4.2 looks like it will be stable for me but 1.31 for 4.4 failed prime

I found the voltage increase from 4.7 to 4.8 was massive.

Do you have PLL Voltage enabled 24/7 for your 4.8 overclock?

These Sandy's all seem to vary a lot from one cpu to another.

Mine needs only a small increase from 4.2 to 4.4 then another from 4.4 to 4.6
4.8 & 5ghz + need larger increases.

Mine doesn't need a lot up to 4.7 but 4.8 looks like it's going to require a hefty jump to be 8 hours stable. I'm probably going to need about as much of a voltage increase to get from 4.7 to 4.8 as I did from 4.5 to 4.7, on current evidence.

what would you consider not a lot? whats your volts for 4.7?

Yep.

Geeman1979 · 25 Jun 2011 at 23:31

Your cpu seems to mirror image mine with said voltages your using.

Yeh I think 1.4 is about normal for 4.8 on the 2600k. I've yet to see any screenshots with significantly lower vcores that are Prime Blend stable. I think the 2500ks require less on average.

1.325 to get 4.7 stable for 8 hours of Prime, which is pretty reasonable from what I've seen. Looks like I'll need somewhere around 1.38+ to get 4.8 stable, though. The only reason I haven't done it is that the temperature during Prime gets uncomfortable, however since everything else I run keeps the temperature a good 10 degrees lower than Prime I'm considering living with nasty temperatures for 8 hours.

If the 2600K is switched Hyper Threading off (disabled) then vcore will be less of course.

But that makes the 2600k pointless lol.

not really, i had both option choice either HT enabled for winter and HT disabled in hot heatwave summer. Useful.

I never understood the point of turning off HT tbh. Surely you buy it for the extra threads and if it makes the CPU run too hot in the summer, just back down the overclock a bit. As someone who has opted for the CPU with the extra threads, it must be because you need them and as such a slightly higher clock speed won't be as beneficial as the extra threads when it gets hot.

bulldog147 · 26 Jun 2011 at 15:44

I never turn off HT for a year thought! It useful for someone elses. I use 4.8GHz in winter and 4.4GHz in summer both with HT enabled.

whipgeez · 26 Jun 2011 at 15:48

hows this?

the temps ok? bearing in mind it's a very hot day today

what would people consider a good temp?

is 1.32 average or good for 4.5?
