x58 xeon vs z97 i7

[schmuckley]

The 4790k isn't Haswell, it's Devil's Canyon, and Devil's Canyon requires 1.35v RAM. He'd have no choice but to get new RAM.

wat?
No.
There's nothing wrong with Westmere-EP.
Haswell does have higher single-thread, though.

 

[myocardia]

wat?
No.

Tell that to Intel. They seem to be confused as to what parts they are making: http://ark.intel.com/compare/80807,75123

 

[nighty2k7]

Correct.
Incorrect. If they were the same, why would Intel call them two different names? Exactly, they wouldn't.

Someone obviously knows nothing whatsoever about Devil's Canyon...

I can only further confirm: DC is the same silicon as Haswell with different packaging/IHS/TIM. Clock per clock identical performance.

VDIMM, the voltage capabilities for DIMMs, are defined by what the chipset is able to support and the board is able to deliver.

With the upcoming Skylake/Z170 platform Intel defines "1.35V DDR3L" as supported, but I'm quite sure that even in that platform you can use 1.5V DIMMs driven with 1.5V RAM (if the board manufacturer does offer that)

I had no idea I'd create such an active thread haha, well thanks for all the info guys this is turning into a fun read

Nope, not even close. Which part of "has more capacitors" did you not understand??

VDIMM, the voltage capabilities for DIMMs, are defined by what the chipset is able to support and the board is able to deliver.

Again, not even close. The reason that the CPU manufacturers denote the maximum vDIMM you can use with any CPU is to keep from burning out/burning up the memory controller, which has not been on a motherboard in years now.

Silicon is the die itself, the capacitors to assist in overclocking are part of the package around the die, as is PCB, TIM, heatspreader.

Again, not even close. The reason that the CPU manufacturers denote the maximum vDIMM you can use with any CPU is to keep from burning out/burning up the memory controller, which has not been on a motherboard in years now.

Since moving the memory controller on die indeed the VDIMM must be withing what the memory controller can handle (haswell thumb rule for 24/7 overclocks goes around 1.7V), also you need a board that enables memory voltage tweaking capabilities. Boards coming in business desktops often lack the ability to adjust Vdimm.

 

[nighty2k7]

But to go back to the topic:
Stay with your X5650@4.0GHz!

I personally upgraded from a i5-2500K@4.2GHz to a i7-4790K@4.8GHz, the effect was quite disappointing in regards to the spped improvements you can feel on a day to day basis. It is noticeable in Photoshop and especially Lightroom with large libraries, but for the most part: I should have kept my Z68/i5-2500K

 

[escrow4]

I have a x5650 clocked at 4ghz, and was wondering how much faster a i7 4790k would be in comparison considering the heavy overclock have on the chip from its base 2.67ghz.

I mostly do gaming, but id like to still keep the capacity to do some editing and streaming work later on in the future.

So maybe I should go for the 5820k to keep the single core power and multithread performance?

Wrong comparison. You want X99 and a 5820K. That 5650 is old crap and an obsolete platform.

You're finally getting it. I'm proud. Haswell can use 1.50-1.65v RAM, but the OP never mentioned Haswell at all. He asked about the 4790k, which is not a Haswell, it's a Devil's Canyon. If you actually owned one, you would know that the range that is safe to use with a Devil's Canyon is 1.35-1.50v RAM.

That is exactly why the OP would not be able to use his 1.65v RAM with a Devil's Canyon, like has already been mentioned repeatedly. Had he asked about the 4770k, the answer would have been different, since it's a different chip, hence the differing name, not to mention the differing feature set: http://ark.intel.com/compare/80807,75123

Heh. those boards are rare.. Specifically designed for Hexcore overclocking with 2 oz of copper, 16 phase power & a Hybrid Silent Pipe cooler.. Supports up to 18 drives, 3 way Sli or Crossfire, 2X Gigabit Ethernet LAN with Teaming & has USB 3 & Sata3.. @ $140 will carry Op to Skylake

"The best CPU VRM Power design for extreme 6 core CPU overclocking
Ultra Durable 3 Technology with copper cooled quality for lower working temperature
Supports newest NEC SuperSpeed USB 3.0 with superfast transfer rates of up to 5 Gbps"

http://www.gigabyte.com/products/product-page.aspx?pid=3527#ov

Well yeah if you can offer warranty till skylake the they're not a bad buy. But throwing 140 at something so old isn't the best idea. X58 chipsets run hot and die easily.

Did you even look at the link to the board he bought?

The chipset has Extreme Cooling specifically for overclocking Hexcores & twice the amount of copper of other boards.. That was Gigabytes best X58 board & will probably out last the one you're typing on..

Don't quote the marketing hype. Boards die, even high end ones, and the older they are the higher the death rate. I've seen enough R3E's die to know that Extreme Cooling or whatever means little. Especially 'made for overclocking' boards, probably means they are overclocked and overvolted for the past 5 years. If you are so sure the boards won't die, why not back up your words with warranty? That would shut everybody up.

The 4790k supports any voltage ddr3 memory.

I've personally used 1.65v dimms on z97/4790k, as have hundreds of thousands of other builders. It works.

Please stop posting nonsense about something you know nothing about.

 

[Dave2150]

X58 is built like a tank. Very reliable. Very outdated platform at this point, though it still packs a punch with a hex-core installed.

Built like a tank? I've seen more 1366's go up in smokes than 775's, and I've seen a lot more 775 rigs!

me too on the 1.6something. xmp merrily set it to such on my 2400

The fact that X58 is over 6 years old and there are still many who are still using their X58 platform, suggests they are kinda reliable.

Look at the X58 xeon threads on popular hardware forums - so much activity there now. so many X58 boards still running strong.

You've got to look at the whole picture. Sure alot of them are still going strong but also a lot have died. As a percentage x58 is a lot more fragile than something like P35.

 

[jforce321]

My board lasted me for 6 years and I'm glad that I've run the platform, but hes right about the strength of hexacores in these boards, as overclocked it easily matches an i7 3770k.

If you are already on the platform then great. x58 has been one of the best intel platforms. But to spend good money now to invest in a 6 year old platform is not the wisest move.

Completely agree, no point anyone buying into the x58 platform at this point in time.

Getting a hex core xeon is only worth it if you already have a x58 board, even then it's questionable spending more money on it, especially since you have no warranty left on CPU or Motherboard, both of which could die at any point.

Have you even seen a Gigabyte GAX58a-UD7 Rev 2.0? Not hype, the 2 oz copper between layers is real as is the Hybrid Silent Pipe cooler & 16 phase power, all designed for high current that Hexcore overclocking requires. 11 of the 12 boards had i7-950's running @ stock, the only i7-980 he kept. They've only seen light duty as workstations, but nobody guarantees used boards. He asked for it Sat. @ noon and it's in his hands Monday.. $140 w/2 day shipping was a gift. Each of the last 7 will bring $200+ on ebay & were $400 new..

Devil's Canyon is a refresh of the Haswell microarchitecture. It's not another architecture. It's just been optimized, clock speeds bumped and features added. Still Haswell. Dimms of 1.65V are supported. It's ok to state something and say your not sure of that. mycardia, you act like an expert on the subject and you are clearly not.

quick BIOS SS
Do NOT listen to all that RAM voltage gobblety-beloved patriot.
Give your RAM what it needs to run at what you want it to run at.
Haswell/DC IMC is very strong,probably the strongest IMC for ddr3 ever.
It will not hurt your chip.
What will hurt a chip like that is running AVX Prime95 for hours...
There have been instances of chip death from that.
You need to know what ICs the RAM has so you're not degrading it, though.
I liked Westmere-EP..it's still quite viable for everything.
on X58..well..you need to keep RAM voltage in check on that platform..on that platform it can cause damage..maybe.
As for x99 vs z97..I vote for z97.
I have both..
Mainly I vote against x99 bcuz DDR4..and lower IPC.
