Help me push 5

[virtualTune]

Alright so I just got a 750D, H105 and fans, haven't had time to set it all up yet. I got my 4770k to 5GHz with a Noctua NH-D14 before. However, I lost her as soon as i put a load on her.
Now I wanna try it again with water. So if you guys have any tips or concernes, fire away

TBH mate they are all so different youll just have to post...LOTS of detail.

bios screenshots will be crucial tbh. getting to 5 is one thing but stable tbh will probably mean a lot more volts than you had it at before and/or working on your other voltages too. There are a surprising amount of hints and tips in our overclocking guide tbh.

TTL himself, what an honor
How can I do screenshots in-BIOS?

As far as basic info goes:
Asus Sabertooth
Corsair Hx1000
CPU is set to 110MHz and a multiplier of x43 at 1.300V under my highest stable overclock.
I'll have a look at the guide. Also, will those little fans that come with the board help me cool mosfet etc. ? I haven't used them yet cause I am afraid they will produce some whining noise.

Uhh, okay.. :lol:

Uhh, okay.. :lol:

wow. i did not think thay way until you mentioned it.


well, 5GHz haswell isn't that easy. even with an h105 your temps will be very high. i doubt it will be viable, if your chip can do it at all

dirty Remmy!

well, worth a shot Cru ^^

Also I have 32 Gigs of ram, which might hold me back as well...

Can someone point me to the guide? I can't seem to find it >.>

Can you not get 100x50 mate?

Can you not get 100x50 mate?

not with current setup (air). It will post, but as soon as I start benchmarks the system crashes.
Before I change my cooling, do you guys think I should delid?

Also, OCCT seems to be an artificial benchmark. As far as I know those actually put a bigger load on the CPU than if I was just gonna render something in Maya?

After a whopping 10 hours I finally have the new system up and running. Amazing how much more quiet it is. Anyways, I'll do some overclocking tomorrow and get back to you with the results.

So I thought tonight would be a good night to do some overclocking. But as it turns out I can not even get into my BIOS anymore.
As soon as I press DEL/F2 I get a Windows Boot Menue with "Windows 7 (Recovered) selected. With F8 I can go into advance options and chose stuff like safe mode, start normally and about 7 others, none of which get me to my BIOS. Any ideas what I might be doing wrong?

updating the BIOs solved the issue. now i just have to find out what all these new overclocking shortcuts in the BIOS mean ^^

I just did some Overclocking. Below are two screenshots.
Granted I only ran the benchmark for 10 minutes, but the point of these overclocks isn't long term stability but rather simply reaching at least short term (an hour or so) stability at 5GHz.

I was quite surprised to see how much I had to increaxe the voltage to go from 4.8 to 4.9. So far I stuck to BCLK of 100. Changing those values may allow a lower voltage?
Right now I also still have the stock thermal paste on the H105. I'll probably change it for the Noctua paste soon.

As you can see I wasn't able to get to 5 yet. At 1.4V (1.425V according to CPU-Z) I got into Windows but crashed before the benchmark even started. I didn't want to go any higher because I felt like 1.4 was already a little insane

Any ideas are greatly appreciated

So I know it has been a while since I first started the post, but I really need your experience/knowledge now.

I finally cracked 5GHz @ 1.450V with a temperature spike at the beginning of 80C but temperatures between 48C and 63C after that. I only ran the benchmark for 10 minutes though, since this was never intended to be a 24/7 Overclock. This was also without Hyperthreading to lower temps by 10-14C.
With Hyperthreading the best I got was 4.875GHz @ 1.400V and average temps at 73C.

Anyways, after the succesful overclocking, I ran into some problems which have now caused my PC to not boot properly. Since yesterday I was able to improve the results somewhat as the PC will now boot, but with a black screen (before I was stuck in a 5 second boot cycle).
I'd really appreciate any ideas you guys might have!
