Basic OC help w/ ivy

Prime 95 is available at XS TPU and Anandtech forums for DL.
A guy named Stasio updates it.

Please note that Prime95 x64 v.26.6 is the current one on the main site WITHOUT AVX.

Further versions incorporate AVX like linpack or IBT and will really generate some heat.

But Linx cant be used to measure temps since doing real gaming which is what I ues PC for will never hit the same temps?

So even though Linx might push 90 I will still be safe in theory?

What temps would you recommend to never go above @ full load for everyday gaming?

It's hard to say. You're probably ok hitting 90 in LinX. In gaming you will probably hit 70 or 80 which is normal for Ivy.

What kind of cooling do you have, OP?

Thanks for the link but the download links don't work there as well

They point back to the same place I should be downloading 26.6 build 3?

I have only air cooling - Thermalright True Spirit 120

If you manage 4.5ghz with that cooler I will be impressed. You might need to back down to 4.4 or even 4.3.

1.4-1.45V was the rule of thumb for SB. For Ivy it is 1.3 or so on high end air and 1.3-1.35 on H100 or so.

For 4.3 you prolly need around 1.2 or less. What cooling do you have?

 

[aaksheytalwar]

IMO I would prefer to keep OCCT load temps under 70C if possible on the hottest core. That is far more intensive than Prime 95 anyway. With my SB I get full load around 55C+- or so at 4.3Ghz.

He's fine with under 90c with stability testing. Sandy bridge has a tjmax of 100c yet everyone tries to keep it under 70c. Obviously the chip can handle the heat.

 

[aaksheytalwar]

Its more of a mentally satisfying factor. Cooler the chip, cooler your cabinet and other stuff. Just feels good. And of course lasts long. Sub 60C you can last a few years without any changes. Nearing 80C your overclock will probably last 1-1.5 years max after which you will either need to up the volts or decrease the speed by 1-2 multipliers.

90C is way too high. Worst case the max load shouldn't cross 80-85C on any core under any stress. And realistically under real world load sub 75C. This if you want your OC to last 1-2 years or so (the chip may of course last much much longer, but the exact oc settings etc may not last more than 2 years).

I finally found a working link but it for Prime95 64 bit 25.11

http://files.extremeoverclocking.com/file.php?f=205

Is this sufficient for stress and stability testing?

 

[aaksheytalwar]

Prime doesn't stress much. Try OCCT and use it for just 2-3 mins, will stress >= Prime 95.

I finally found a working link for Prime 95 x64 26.6 build3, in case anyone else is looking for it

So, i just read this thread and wanted to say, i dropped my PLL to 1.6 and set my VCore to 1.210 and my multiplier to 45...My temps on standard LinX tennis were mid 70s max. You should be able to get the same or close to it. It passed 20 passes in roughly 20-30 mins. Doing a Prime95 blend test right now. I'm also using Prime95 v. 27.7

 

[nearsite]

Hey guys, what does offset voltage do?

 

[MPiland]

Ok, crashed at the voltage so i upped it to 1.22 and running tests again. Offset is another way of controlling the voltage. Instead of being a set number, you give it a range. If you leave speedstep on, it will lower it for you at idle.

90C under IBT is NOT too high. You don't own ivy so stop spreading misinformation

 

[aaksheytalwar]

I know how how Ivy gets.
