SB Overclocking Thread

See what voltage it takes to run at 5GHz and keep it at that.

you buying?

Sorry, I cannot. The assurance that comes with knowing someone else will buy you a replacement will minimize the thrill of living on the edge. You have to do this on your own. You can do it!

Some of us can afford to waste money, others just want to have fun without throwing away money.

Where are the threads from users on this site or otherwise reporting killing their CPUs? I'd like to see them.

Did you used the fixed vcore or set it as offset to get the 1.29? Also, did you adjust the long load power limit? If not, I wonder if the board automatically adjusts this up when doing the auto OC. Do the intel burn test and watch CPU z and see if your multiplier drops a little, should happen within 5-10 seconds.

I used fix vcore. Did not yet touch long load power limit or any other thing.

There are several, warning to NOT go over 1.35, and the only 5 ghz plus boxes had to use way over that.

 

[AdamK47]

Several warning. Where are the several dying?

OK, here is one... aigomorla... When he speaks, I listen

Fun to see people do it and pull it off but I'm not frying any chips.

How is this "standard" value determined? When I use the offset feature on my Asus P8P67 Pro it appears that the offset is applied to the value determined as when set to Auto.

I'm curious about this myself. Perhaps it has something to do with VID?

That is how it is supposed to work. On stock settings (normal multiplier) 'auto' will use the voltages that are identified within your specific cpu, which are indeed read from the VID table. The offset feature allows you to lock the vcore to these values.

If you'd leave the vcore on 'auto' and up the multiplier it will increase the vcore, usually much more than necessary.

Then isn't this a problem when using the offset? For example, say I set the multiplier to 40x. My VID for this multiplier is about 1.34 V, which is probably more than necessary. I can use the offset to subtract from this, but then that might create instability at low multipliers when EIST and C1E kick in. I expect this only gets worse as the multiplier increases. Am I missing something here?

I had to put 1.50v through my 2600k to get it benchmark stable at 5.3Ghz, but after i'd run all my benchmarks i put it down to a nice 24/7 overclock of 4.5Ghz @ 1.24v.

Still waiting for some passmark results? Anyone? And on stable systems if you would.

 

[scrubman]

After much trial and error my best/stable/low temp is with using the boards auto OC setting at 4.4GHz @ 1.25vcore. 4.4 is definately the sweet spot on my SB. 4.5 with manual setting may work ok but I didnt feel as good about it becasue I'm not sure of the best settings to tweak as the auto OC makes tweaks that I am unaware of.

Bottom line is after 4.4 I have to make a pretty big jump in vcore (from 1.25 to 1.32) to get stability @ 4.6 in vcore which pushes my temps using Prim95 up to 90c - Not worth the extra 200 MHz. Maybe with a new BIOS I might play again but for now I'm quite happy!

 

[Axon]

Same for my 2500k. I can get it nice and stable at 4.4 and 1.25ish, but beyond that I have to get crazy with the volts. Not worth it at all.

Is this what you want to see? If not lemme know which other tests.

 

[slag]

plugged it in, before even booting up the first time i changed the multi to 41 and it came right up. Re installed windows at 4100 and its steady so far at stock voltage. Going to play with it some more here after lunch after my inlaws leave.

 

[StinkyPinky]

I also have it stable at 4.4. That seems to be the sweet spot for most people. After that the voltage needs to be ramped up and I really can't be bothered doing that for something that has no real-life improvement.

 

[M1A]

Thanks D4 you are the first, exactly what I was looking 4

 

[Castiel]

I haven't seen any posts besides the ones from the UK about chips dying. Maybe they were overvolted by faulty mobo's

 

[AdamK47]

Just for comparison, this is my 980X @ 4200MHz.

Imo, you have to take the information out of uk overclockers with a grain of salt. Reason is, they are one of the few etailers, I know of that profit off of overclocking. They market it and charge a premium for it, and with that comes some warranty. They want people to NOT go crazy and not have NO FEAR. They probably feel its in their best interest to remind new overclockers that there can be consequences. Some people might not realize this. A combination of beta , first run bios's, voltage spikes and unmonitored heat, and core voltage's could kill the most bulletproof made electronics. Which imo, Intel cpu's are

Here is mine, but under winxp32

Still rockin XP? You're not very good at math.

 

[Xellos2099]

What setting I need to set in the bios to get my 2500k to 4.2? I try to set the cpu voltage to 1.300 and the system freeze on me after a while. What other setting I need to use? I am using the asus board btw.

 

[Bryf50]

Think I found my stable setup that ill run 24/7. I have speedstep disabled but I have C1E and the other c states enabled. Set up this way it stays underclocked and undervolted when idle and the second its under any load it goes to the maximum clock.
