2600k to 4790k

Hey,

I have a Maximus IV Extreme and I was considering upgrading to the Maximus VII Formula when its available here in the UK along side a 4790k.

I know the memory controller on the 2600k is not the best and it usually prevented me hitting higher cpu clocks when tuning in higher ram frequencies. has this improved for the better these days?

I would have been thinking of 2400mhz ram or at least 2133mhz ram at 4.6-4.8 cpu oc if i get a decent 4790 cpu.

Would this upgrade bring me any worth while benefits if i was doing it for CPU and RAM benefits mainly?

thanks.

Nope, The improvements since Sandybridge have been pathetic.

Wait for the next round of CPU's.

If you mainly game you will see no benefit, You will see some little benefit if you encode a lot but that's really it, Save the pennies and wait for Broadwell.

4.6 would be a good overclock dude. 2400mhz is easy peasey but you will need to know how to set things up.

If you had a 4790K at 4.6 it would be like having a 2600K at like 5ghz+
 
I'm not too sure how much of a performance increase you'll get, but to put some things in perspective for you...

I've got a 4790k on a Z87 motherboard (Upgraded from a 4670). It's OC'd to 4.5 GHz at 1.150 V in the bios (It bumps to 1.168 V so +0.018 V) perfectly stable and well under 1.300 V. I have an H100i cooling mine. Idle ~ 24 C, Gaming ~ 56 C, Ambient Room Temp ~ 22 C.

If you get a decent chip and have solid cooling 4.6-4.8 should be reasonable (Just depends on a voltage you're comfortable with).

I also have 2133 MHz RAM installed (2 x 8 Gb). I upgraded from 1600 MHz. Both G.Skill Ares.

Runs like a dream and I saw a significant gain in performance.

Also Check these links out if you haven't already:

You can search for your CPU, and compare the CPU marks (4790k: 11,441 2600k: 8,593) as well as Price per performance values

These charts might help with choosing memory.

Just suggestions, and some experience with the hardware you want to upgrade to, Hope they help.
 
Save the money, IPC improvements range from 5%-20% across multiple applications including games, synthetic benchmarks and even emulators.

Intel literally have had no reason to take it that one step further for some time now and it's really frustrating to see.

Wait for broadwell or even save up a bunch for a X99 setup!
 
Hi,

I'm not a pro at OCing. So I wanted to ask the best method with this set up. I do like some of the features and look of the VII formula which is why I've chosen this board.
(Maximus IIV Formula and 4790k)

Is it a case of just altering the Vcore and leaving everything else other than what ever the Ram needs to be set as?

After I've ran the rig a while to ensure all stock settings is fine..

Would I be better off doing the following ...
1.250v @ 4.4Ghz and finding the lowest 4.4Ghz Vcore before going for 4.6Ghz?

So the aim here is to hit what ever I can that is under 1.3v, is that right?
As I assume 1.3v on this chip 24/7 is asking for trouble?
I will be using a quad rad to cool just the CPU so cooling it should not be an issue.
Or is 1.3v safe if the temps are consistently controlled and kept below like 70?

Am I am the right lines here?

Thanks

1.3 is actually ok for 24/7 use but obviously lower is better and cooling has to be spot on, Intel recommends not going going over 1.45v *According to their Haswell spec sheet* although you should never go over 1.35 realistically as the temps will be insane and the chip will not last as long.

But hopefully you will be in the 1.2+ area with the 4790K at 4.60GHZ :)

Thanks for your help.

The other question.... if all 4 slots for ram was populated and with 2400 ram.
Could either or both of these factors effect the OC results?
 
Hi,

Well I've just watched Tom's Review on the board and I must admit I'm some what disappointing about the M2 spacing.
I was going to invest in one of those Plextor M6E cards.
Bad move Asus!

So it brings me to rethinking things.

I'm looking at a high end board. I want Sata Express and was liking the idea of CrossChill hybrid cooler option as well although I know it's not a big deal.

I was wondering what other really nice boards people would recommend to accommodate most if not all the above as well as being able to fit a longer M2 card?
 
M2 is really new and we are waiting for more releases of both the SSD form factor itself and the motherboard revisions too so you are short of options for now. Either wait until more are released or go with a sata-e 2.5" mount which are currently performing on par or slightly better at the 4K level.

Regarding your question about RAM. Yes the more you stress the memory (in both capacity and slots and frequency) the more likely it will affect your CPU clock. Core is still king for most applications depending on your uses. I would OC the core with a lower RAM freq first (say 1866) to find the best CPU clock/volt ratio and then push the RAM up after that. If you want high RAM freq first then dial that it and go for the CPU clock after.

Hi

Thanks for that info :)

So I'd be better off getting 2 x 8gb ram sticks and would I be better off getting 2400 ram then down clocking it to 1866 so I have the above head room to move up on ram frequency once thr chip OC is stable?

If that's a yes, with XMP or setting the timings manually you have that info readily avail.
How do you know what timings are correct at lower frequencies for that specific ram?
Let's say ram that would do 2400 @ 1866?
Do you just use the rated timings on all speeds you set?

I've had a look for one of these.
Would you be able to please link me to one so I can have a look at one of them?

Can anyone offer any help/advice on the last two replies I made please?

Thanks

Regarding the RAM:
Quantity- Yea get 2x8GB sticks, that will be plenty for you and the best case scenario for overclocking.

Speed- Two options. If you can afford the higher speed RAM as part of your budget then this is best and easiest option. If you want to save money then buy something like 1866MHz and overclock it but that is only an option if you know how to overclock RAM.

Downclocking RAM- Easiest way is to type in the timings on the sticks as they are at 2400MHz (assuming you buy the faster kit). Since those timings work at 2400 then they will work at lower speeds. Just leave them be and lower the frequency to 1866. If you want to tighten them later then you can - best reference to use is to look online for the same model of RAM you have but the lower speed variant and copy those.

Regarding Motherboards
Many z97 motherboards have both M.2 and Sata Express. ASUS and Gigabyte certainly do but MSI in both their Gaming and M/Xpower ranges only include M.2.

Brilliant. Thank you for your help :)

I shopped around and made a few purchases.

I was going to go with the Corsair Vengeance Pro Red 2400.
But I found G.Skill TridentX 16GB (2x8GB) DDR3 PC3-19200 2400.
Timing are a little lower and they offer good timing at lower frequencies.
So I decided to go with that. Here's hoping I don't have any incompatibility issues with that ram.

I was wondering what a good performing CPU block was these days?
I've been looking at the EK Supremacy range, but I was wondering if EK got their act together with the Nickel plating flaking issue?

And if they are highly recommended or if there is something else to consider?
