Opinions on safe daily voltage for SB

[AH64]

any idea on what the "range" is for safe daily use?

currently running prime95 with my 2500k, 4.8ghz @ 1.368v under load

[Leeghoofd]

If I said 1.3 would you lower ya clocks ?

Dunno mate, think only time till tell, settling at the moment at 4.5 at 1.28 with the 2600K. Tops at 71°C under prime95, around 62°C with Battlefield Bad Company 2... high enough for me...

1.4V should be safe. 1.45V "seems somewhat safe". Everything above... I wouldn't call safe 24/7.
Keep temps under 70C at all times as well, just in case.

watercooled, so temps aren't an issue so far..

Been running since day one linX at 5Ghz, with volts going around 1.5v, till now it's all ok. Seems pretty safe for me.

How long has it been?

[st0ned]

Yesterday I let it running with 1.52v 25 runs with All the memory, I've 8Gb it should have been like 3h's... and the rest of the night on idle. Today I've tested with 1.49v it runned till the 17th After that I had a BSOD. Thought I'm having much lower temps compared to some posted here around XS ( still I'm on water ). But I'm might have another crappy CPU I wont be very sad if it dies...

What batch # is your chip? 2500K or 2600K...

2600k. L039B470. I think of myself as a quiete experienced overclocked, but it could also be me playing wrong with BIOS settings, I hope so...

I need 1.3v for a 25 linX runs at 4.6Ghz, but from there on I've to push quiet a lot of volts to get get more Mhz

[wazoo99]

so what do you guys think of this?

[PolRoger]

Yeah not all these SB are going to be 5GHz with 1.40v to 1.45v load... I think with time will see more average chips as well.

I think it's bullsh*t, intel datasheet states VIDmax : 1.52v . This doesn't mean it's safe, but in my understanding it means that it was somewhat design to handle those. Plus it also stats that max Icc it's 112A. Mine runing at 1.52v on Linx takes around 104W, that means it's pulling around 69A, much lower then those 112A...

[dinos22]

^ nothing basically which is same for everyone else here saying this or that volt is safe

my suggestion is for a 24/7 machine find your max clocks with stock voltage or a slight bump that's it. These chips can do 4.5GHz with around stock voltage almost.

I'm doing 5.2 on 1.485 on LLC lvl2 temps are low 70's high 60's. I'll check how much I need for 5.1.

Not actually the max supported VID, just the highest value possible on the SVID encoding.

I was in your boat, but higher vcore, and was able to drop vcore .6v and LLC down to level1. For 5.1.

[skeyo]

@ sin that's what I'm testing now :P

[st0ned]

Just to warn all of you, my CPU has officially degraded. I haven't played with the other volts so it mush ( should ) be vcore related . I wouldn't say also that 1.45v is safe, since 1.5 isn't. Maybe those 1.38v wondering around the internet aint so that unreal

[zalbard]

Should've listened to me. Sorry about your CPU, though.
I think you're the second or third person on these boards with dead or degraded SB...

[GeorgeStorm]

How can people think such high voltages are safe?
1.4+ was considered high for wolfdale for 24/7
So obviously SB won't be able to cope with as much.

[Metroid]

1.375 ~7 years. 1.60 if planning to replace it soon

Don't be, I ain't. Only thing is that I've to afford another 2600k until this one comes back from RMA, still I aint abble to do it yet, he is still stable at stock volts stock freq...

If it was a gem I would be sadder

Those who forget history are to doomed to repeat its failures and not enjoy its successes! What a way to waste good tech!

If it was a gem then it would not have died.
