Guide to Overclocking the Core I7 920 or 930 to 4.0ghz - Page 147

Hey one comment to your post, try to post at the top in BOLD

Stock O/C to 3.8ghz You should be able to a bit more out of that chip I would think, otherwise switch to the Xeon like a lot of us did.

Hey man thanks for the tip, I added a header.

3.8 is way beyond what I thought I could get, so I'm not really looking to push this 930 any farther. But I did look at the specific thread for my mobo, and it looks like plenty have already switched to the x5600's. After I've gotten some mileage out of this setup, somewhere around next Christmas I'll definitely take a look at Xeons, at least if everyone hasn't snapped them all up by then. With 8 cores in the new consoles, games might just catch up to hex cores later this year or the next, which is the only reason I'd ever need one.

Hi everyone, first post in OCN.

So I'm extremely new in the art of overclocking and I'm quite noob about pretty much everything. Did some research here and there and tried oc'ing my cpu only to get blue screens after blue screens and was about to give up till I found this thread. Tried to use the first post as a guide but there's simply too much information for me to follow.

So I'm just gonna post my specs and plead for some help from you guys, I'd greatly appreciate it.





And the AI Tweaker screen is this one:



it's ok if my cpu won't hit 4ghz ish speeds, but I'm ok to try my best. I just want the cpu to hold on till skylake hits. Gonna play the likes of The Witcher 3, Arkham Knight and such and need a bit more cpu power.

Thanks in advance!

Try this. Your mobo settings are similar to my p6x58d mobo. Play around with the BCLK freq for your ghz. I think 200 is 4.2ish. Then adjust your CPU voltage as needed after stress testing with prime95, intel burn, etc. I have all my settings the same here except my CPU voltage takes 1.3. YMMV.

Great guide. I used this back in 2009 to get my 920 4GHz stable. Been running it for over 5 years. I recently messed up some ram settings trying to run my ddr3 1600 @ 1800 and had to reset cmos. I looked up this legendary guide again to get my settings back. Thanks OP!

Check out my settings shots:

I am trying to set right voltages. System boot from 1,18 up to 1.3 and higher (cpu voltage) but it is unstable. Test in prime lasts about 5s and screen freezes, then I have to make hard reset.
I setup memory (everything else too) according to the guide - at 8x, but the timings are on auto. Did I forget about sth?
Please give me an advise which setting should I change to get stable 4ghz?
TY,
kamizelka

I know you posted this 6 months ago but thought I'd chime in.

I got the same board, same chip, and almost the same settings as you. I would check your ram timings and change the command rate to 2T. That solved blue screens for me. I have my 920 @ 4GHz 1.25V IBS stable.

3.8 is honestly the best oc for this cpu. I've gone from stock clocks to 4.2 and eventually dialed it back down to 3.8. The realworld gains are not worth the additional wear and tear going any further. It's a nice sweet spot for performance and efficiency.

I followed this guide and got my d0 920 up to 3.8Ghz with the voltage at 1.225. I ran Prime95 for 24 hours straight and while the temp got up to 90 degrees C, it never crashed or froze. I went back into the BIOS and reenabled the two power saving modes I had disabled. I have an Asus Rampage II Gene board and I can't remember the exact name of the settings, but they seemed to match up to the ones that were recommended to disable when overclocking and to reenable after. The only game I've played so far is SWTOR, and one of the times I was loading up the launcher I got a BSOD on Windows 10 that said "clock_watchdog_timeout". From a little googling it seemed like this is related to an unstable overclock. I bumped up the voltage to 1.25 and it worked fine for a day. Then this morning when I was turning on my PC (I had turned it off before I went to bed last night) it wouldn't boot and told me that an overclock had failed and forced me into the BIOS. I upped the voltage again to 1.275 and it booted up fine. I'm curious what I should be doing at this point. I felt pretty confident that the overclock was stable since it lasted 24 hours without any trouble. Only thing I can think is that it is because I reenabled the power saving modes. Should I continue to up the voltage and hope it gets stable again, or should I disable the power saving modes?

Having issues overclocking my 930 D0 with an MSI Big Bang XPower as the mobo. Any time I change the bclk my rig shuts down, turns on for a second doesn't post and turns itself off, if I try to turn it back on I get a message:

"User set to boot from USB. Starting to boot from usb.... Your USB Boot function setting wrong, function will disable and reboot." then it Reboots and doesn't post, I also don't know why this message comes up because I don't set anything to make it boot from usb I was just trying to overclock



I was trying following method #1 and can never seem to get any BCLK to post above 133 x 21
Can't seem to mess with my memory settings much at all either to set to 8 or 6 with x2 the uncore.

I'm lost and am wondering if I'm leaving a bios setting enabled or disabled when I shouldn't.
For images of what the BIOS basically looks like you can refer to this if anyone can help me out.

I've been trying to push my old i7 920 further than i have before since i got a fancy cooler and have some free time, but i've run into an issue on my asus p6t deluxe v2, according to prime 95 its doing the cpu throttling thing mentioned in the OP:
Quote:
Q: What is this multiplier throttling I've heard about?

A: Some boards will throttle down the 21x multiplier if the wattage becomes too high. The culprits without public fixes are the Asus p6t deluxe and vanilla (The deluxe v1 has a bios available on the xtremesystems forum which can be crossflashed onto the v2 which will fix this problem) It really only becomes a problem at high voltages with high frequencies. Other boards have ways of disabling it.
Even worse than just impacting my performance, i suspect that this issue is also responsible for some odd problems i've had where 4-60 seconds after an intensive application closes and offloads enough memory, i get a crash, again just a guess but i can see why suddenly ramping up the ratio at a high base could kill my stability.

Im looking for some more information on whether i can safely crossflash the custom bios on the xtremesystems forum to the v2, and if it would even be worth the risk. I can push higher on 21 ratio, but 19 is useable too. Or, even better has anyone found an alternate workaround to keep the 21 ratio steady?

A: Thanks to Hammer=GOM= there is. He also provided a helpful link to software which will help you see what error code was displayed:

BSOD viewer:
http://www.nirsoft.net/utils/blue_screen_view.html

BSOD codes:

BSOD codes for overclocking

0x101 = increase vcore

0x124 = increase/decrease vcore or QPI/VTT...have to test to see which one it is

0x0A = unstable RAM/IMC, increase QPI first, if that doesn't work increase vcore

0x1E = increase vcore

0x3B = increase vcore

0x3D = increase vcore

0xD1 = QPI/VTT, increase/decrease as necessary

0x9C = QPI/VTT most likely, but increasing vcore has helped in some instances

0x50 = RAM timings/Frequency or uncore multi unstable, increase RAM voltage or adjust QPI/VTT, or lower uncore if you're higher than 2x

0x109 = Not enough or too Much memory voltage

0x116 = Low IOH (NB) voltage, GPU issue (most common when running multi-GPU/overclocking GPU)

Mother of god!!!

God bless you my son! biggrin.gifcheers.gif
