I play with Haswell 4770k 2 month ago and I like it smile.gif

I testing many motherboard : ASUS Maximus VI Hero / Gryphon / Z87X-OC / Z87-G45 and now I test over GIGABYTE MB.

My 4770K is good I think : 4.6GHz 1.18v Vcore but after is complicated... 1.24v for 4.7GHz, 1.32v for 4.8GHz and 1.40v for 4.9GHz boot but many BSOD ( 101 )

I always left the cover ratio at least 35 regardless of the CPU frequency, I have not found better performance by increasing the ratio.

My memory are G.skill TridentX 2 x 4GB 2666MHz 2800MHz which take without changing

I'm looking for advice hope lower Vcore to 4.7 or 4.8

In advance thank you to all.

 

As you go up you need more voltage, I don't see anything wrong with that. 1.32v for 4.8ghz is very, very good.

i've actually seen instability from moving from 1333 to 1600 with my CPU at the same volts. memtest are OK. since i'm at 1.29V for 4.4GHz (feel free to feel sorry for my crappy CPU), i don't want to run 1600 because it would definitely need 1.30V or more to make things stable. i wanna keep the Vcore below 1.3V.

but i wonder if running 2 sticks rather than 4 sticks might do the trick. if that is the case it would sell my RAM and get 8GBx2 sticks.

i have not changed them... should i? An i that case, what should i change it to?

Depends on how you have it set and what it is actually running at. Normally you want to keep the cache speed low while you are doing the initial overclocking just to keep that from being the limiting factor for your overclock. Sometimes Auto will stay at 38x or so, which should be fine, but sometimes it may go higher which could cause crashes. I'd set it manually at 36x until you get a stable core overclock, then worry about increasing it. You may also want to set 1.1V or 1.15V for the Cache Voltage, even with it set to 36x - that can help stability as well.

Ok, thanks ;-) when I cone home im goibg to try a 1.30 core voltage and fix those cache settings.

Hello,

Yes compared to what I see is really good.

Now I'd like to play with RAM (2666MHz CL11 TridentX 2x 4GB)

It is 2800MHz without changing anything and 2933MHz in CL12. at 1.65v

I'd like to go beyond the 3000MHz but I know not all the secondary and tertiary timings.

So if you can help me AC is super nice smile.gif

PS : I spent a wPrime1024 to 1.37v for 4.9GHz

Use Maxxmem as a quick benchmark, set it to high priority on the program. If you're making performance improvements, you'll get higher memory copy, read, write speeds, and/or lower latency. People clock RAM higher all the time and actually lose performance from it because they don't check their benchmark

Here's mine


Your Vcore just seemed overly aggressive to me, like you were having to add too much too fast. I've never seen such sharp jumps on haswell unless somebody was unstable from uncore or (big one) setting VRIN far away from optimal settings

Hello,

Yes, usually I look bandwidth with AIDA64.

Sorry, I'm french and I did not understand this:

Thank you wink.gif
