come on stasio,with your 3000mhz ram

come on stasio,with your 3000mhz ram

Just got 2 days ago and is 2933 (not 3000).
No much time to play...yet......

Z87 has multi up to 2933 (Z77 up to 3200 !!)...so any higher value, must increase divider or BCLK.

Edit:
You using outdated AIDA64 !
And must be "golden" batch Haswell to run above...5GHz on air.

Re: Haswell Overclocking Guides / Results

its an old pic im not risking 5.3ghz again

congrats on the mem speed though,much better clocking on haswell

Re: Haswell Overclocking Guides / Results

Yea,much...much better....on 3770K, max I can squeeze DDR3 2720 (daily 2666).
On 4770K,I fill can go above 3300....(will check soon)......

Re: Haswell Overclocking Guides / Results

Today DDR3 3100 (tmr 3200).....

4.65 GHz-DDR3-3100MHz [email protected]

DDR3-3200......

Re: Haswell Overclocking Guides / Results

well this new LinX 0.6.5 with linpack 11.0.5.009 is hammering my cpu. Was running LinX 0.6.4 with last linpack that worked with it. Was good with 1.21v up till 4.2ghz, 4.5ghz im up to 1.330v and I still testing. I think I found one of my other voltages to low so I might be able to lower vcore. I might be able to break 200 gflops at 4.5ghz I am getting around 189 192 ish.

Well looks like passed 200 gflops.

Re: Haswell Overclocking Guides / Results

^Yea,seems with LinX v.0.6.5,is normal to pass 200 gflops and above....

Re: Haswell Overclocking Guides / Results

Have you run the new Prime 95 beta? Zowieeeeeee.......it put another 10* on my cores.

So I did the only logical thing I could do. DELIDDED, BABY! This time for grins I did the "vise and wood" method. Don't have any numbers yet as I still have system down working on a new light panel.

OBTW, good job Ace!

Re: Haswell Overclocking Guides / Results

just tested mine to compare 121 gflops



200gflops @ 4.5ghz is crazy

linx sure does cook the cpu

Re: Haswell Overclocking Guides / Results

With new LinX I am strugiling to get 4.7ghz. I tried all the way up to 1.450v and still crashes when cpu its full load. One thing I notice is that Temp is more effected by voltage then it is by cpu speed. At 4.5ghz with 1.33v core are at the same temp as they were when I was 4.7ghz with 1.330v testing with old linX.

Re: Haswell Overclocking Guides / Results

A very novice question, as I still don't grasp much of the OC guide. Is setting CPU core ratio only to 42 significant for OC (over the stock 34), w/o touching voltage or any other settings? I don't have intentions of OC'g memory w/c is just currently in XMP. Am I getting any advantage, or just better leaving it to stock 34? Thanks.

Not sure if I fully understand your question, but yes setting 42x cpu multi will be better over stock. I am not sure if you can set cpu multi to 42x with out touching any voltages. It should do it but the bios may over volt if voltages are left on auto as posed to manually setting voltages.

You will always get more performance from a cpu then you will get from memory. If I test ram at 2800mhz vs 2133mhz the gflop difference is probably about 2-4 gflops different. yet raising from 4.2ghz to 4.5ghz will give you something like 10 or so gflops. These are just rough estimates not true numbers.

Re: Haswell Overclocking Guides / Results

any overclock will be a performance boost over stock
