Too hot to be Ocing right now i'll give it a go soon when the ac is on

I have been enjoying the Intel experience

Won't be long til winter now mate, then the proper overclocking can begin!

Here's a snip of the temps I get for the first few mins of switching the PC on in the cabin in the winter. It's so cold in there and stays that way for a good 30 mins until my little heater finally starts to warm it through.

0C is 32F. We have that in Florida.

Look at his core temp picks in that post, it reads 0*C

He's in a cabin outside without the heat on in that picture. I'd have to do it by remote desktop.

Earlier I posted some winsat scores of 31,000+ on the i5-4670K Haswell, 16GB GSkill which then dropped to under 28,000.
The system has transmogrified to a i7-4770K on an ASUS Z87-WS, work station board with a new set of the same RAM. These scores are even more shi**y, any ideas my friends?

Gary, best I can do for the moment Haswell Overclocking Thread [With Statistics] The discussions will teach a lot, but is a long read. Haswell seems to be quite different than Sandy/Ivy. Those 'rules' do not apply to Haswell. Right now, I think overclocking and BIOS settings is a work in progress, as with any new technology.

What is the exact ram you are using Gary?

Sorry, I thought I put it in there.
Newegg.com - G.SKILL Sniper Series 16GB (2 x 8GB) 240-Pin DDR3 SDRAM DDR3 2400 (PC3 19200) Desktop Memory Model F3-2400C11D-16GSR

Thanks Steve, I'll try to read it, but every time I open a OCN page the damn page locks up...all/any of them.

Right:

My problems with OC'ing using the built in OC profiles are as follows:

I am repeatedly getting BSOD's when OC'ing above 4.4 GHz. All or most of them seem to indicate that VCore is too low, or that VTT/QPI need to be increased. I have these values set at the defaults applied by the profile. CPU VCore is set by the profile to a fixed value for each OC stage, but I am considering shifting to Offset Mode.

Now my questions are:

1) At 4.4GHz, the automatically applied VCore is 1.168V, and AIDA shows the idle VID as 1.2560V. When running IBT (this is the highest speed I can get it to run at without crashing, currently), VID rises to 1.2660V max (range under load 1.2510-1.2660).
--- What is my Offset and how do I calculate it.

2) What value should I set for VTT/QPI? This board has two values for VTT (VTTCPU1 and VTTCPU2), which may or may not relate to the 2 RAM Channels.

3) What should I set my LLC value to?

BTW, these are the BSOD codes for Ivy Bridge:

BSOD Codes for LGA 1155 Ivy Bridge
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, can also be unstable Ram, raise Ram voltage
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)
0x7E = Corrupted OS file, possibly from overclocking. Run sfc /scannow and chkdsk /r

Pillainp Im on my phone so its hard to browse the thread but Kelly posted a great explanation to calculate offset. Steve did too so go back through this threaadd and the post your oc one and you should find it.

pillainp, This is the guide Dude was refering to. It is for Asus motherboards, but the principals are the same. No matter what board, the CPU works the same, just different boards have different termonology for the same thing (which is rediculous). But, a lot of the terms and the options in bios are explained. Ivy Bridge Overclocking Guide#

Also, it is generally a bad idea to use the software overclocking. Most overclockers will agree to that. Do it manually, and you will know and be able to learn the bios and the effect each setting has. Software, which are the built in profiles, are usually just good guesses at what it will take, and are usually wrong as you have found out. Plus, you have no idea what was changed or what it was changed to.

With all the issues you have been having I am glad I went the other way

Maybe Haswell is a bust I don't know but I had my share of issues but now there gone

Can't imagine what is going on the settings are totally different

Best the i7 4770K can do for me. HT is disabled, is that what most of you guys do?



I tend to agree Tommy, the do keep issuing updated UEFI/BIOS for Haswell boards.

I don't disable hyper threading. I do think Paul did on his latest run, but am not sure.

Yeah anything over 5GHz I disabled hyperthreading iirc.

That is actually very good Gary, I must admit I wasn't sure if most Haswells would go that high.

You are getting through cpu's like I have hot dinners, you are taking over the leaderboards lol.

Updated.
