New RAM chips XMP profiles not working

[Ferrum Master]

I have checked out plenty of reviews..

I didn't read them, I loaded up my saves at same places... That applies for my system.

And.. for the sake of being a pain we shall summon @cadaveca. There is always a deviation. It just depends on the system tuning. Dunno what those chaps did do. As long the overall system latency goes down, it should bring few more FPS if a bottleneck somewhere else is not present.

Well, its not like you are missing any performance running at 1600...

i have the exact same CPU as him, and going from 1600 to 2133 definitely boosted a few benchmarks of mine. When you have a CPU that can overclock to the moon and back, the extra ram bandwidth does not go to waste.

 

[EarthDog]

Any may not have been the right word.. negligible may have been better. There are empirical tests all over the web guys... take a read... I already provided links. Again, there are a RARE FEW excpetions.. but the rule is maybe 1-2% if that. You are welcome to provide links so I can learn if my ways are wrong.. I provided a couple supporting my POV...................... Here is another from back when your CPU was new: http://www.anandtech.com/show/7364/memory-scaling-on-haswell/7

As i said, some games NOW may use it, but they are, by far, the exception.

Now, it DOES help with an iGPU (as it uses system ram) and with multiple GPUs (because of the sheer amount of data passing through). But this user is single GPU.

Might consider resetting factory defaults in bios, since u have added new ram..Might help pick it up better but you'd have to redo all your bios settings.
Check if the memory is set to a linked speed to the CPU, try unlinking it.

I've already tried resetting factory defaults believe it or not :/
Hmm how do I go about checking if it is linked? I haven't any knowledge on that whatsoever.

Or you know, just double post again......

I have checked out plenty of reviews... in fact, I am a reviewer (now, that doesn't mean I can't be wrong, please note). But that said, there are very few titles that respond to ram speed increases. You named some.

Here are some links: http://techbuyersguru.com/does-ram-speed-matter-ddr3-1600-vs-1866-2133-and-2400-games?page=1
DDR4 - http://techbuyersguru.com/gaming-ddr4-memory-2133-vs-26663200mhz-8gb-vs-16gb?page=1

EDIT: On that platform, or DDR3 in general, we always said the price to performance sweetspot was in the 1866-2133 Mhz range, above that the improvements are nill and not worth the cost.

But seriously, mostly negligible improvements with ram speed outside of a few select titles.

Ah yeah I know it's only the select few games that benefit at the moment but it is interesting to see that it's somewhat worth upgrading RAM nowadays, especially with my old i5 anyway

I managed to avoid double posting this time around haha

I'm a dual GPU user, CrossFire setup. I wish I could remember video clips that I watched on this subject but it was just after Christmas when I watched them.

Have you tired setting manually after turning off XMP profile?

I have indeed :/

 

[Ferrum Master]

It ain't that bad. We are actually arguing about few matchsticks. The problem with reviewers is that they often take one module and just change the frequency and few first order timings and maybe actually... the other timings are actually very important too(often not even being told). You have to spend a hell of time to bring out the max of your set and prove it is stable afterwards.

This chap here actually is fighting the usual problem with insufficient VCSSA, that's why he cannot boot the sticks. Sandy bridges go to 2400MHz max, with rare examples capable of 2600MHz.

You have to loose up the timings to some 14-14-14-40, up the RAM voltage to 1.65V and VCSSA 1.2V at least for a first try, then drop to 1.15 if it boots at least on 2.4GHz. if it boots, try to lower timings until it bsods, then rise up and do some intel burn test, to check calculation errors.

If it's not an obvious setting in bios, it's not on your mobo.

Have you tried clearing the CMOS. That could be the problem, always a good idea when changing Ram

Memory is not typically a/the bottleneck... let me try to put it another way... if you have a outdoor water faucet and it puts out 1GPM (data), you attach a garden hose to it with the same flow rate its still 1GPM. Now, if you hook up a firehose to the same 1GPM flow, do you magically get more flow just because its a bigger pipe (bandwidth)??? (no)

This is PART of the reason why the increase in games are typically negligible... again there are exceptions.

EDIT: As far as that testing above... Metro: Last Light getting 300FPS, even with a 980Ti, can only be done at lower resolutions than 1080... that is the point at which memory could see more significant improvements... that said, it isn't a realistic result running at such a low res or low settings (not sure how the hell he tests I can't see it in the reviews!!!).

Anyhoo, I think our points have been made.... I digress on that subject.

I literally just went through this on my i7 2700k...just upgraded from a i7 950. lol... Anyways XMP did not work at all as there is NO XMP Profile setting for 2133Mhz. I had to manually set all timings...including advanced timings. Sandybridge doesn't support anything over 2133Mhz. See if you can run at 1333Mhz...If you can go lower, then you can go higher but you will have to manually set every timing and it took me a very long time to get my ram running stable at 2133 10,11,11,28.

One other note..if you are using any BCLK overclocking (In my case even +5 MHZ) it will make the system near impossible to get the ram stable. Keep BCLK at 100 and just use CPU Multi.

 

[rtwjunkie]

Wrong! the reason why I went for the upgrade was indeed for the better performance for CPU intensive games like Fallout 4, GTAV, the Witcher etc current gen consoles use 2400Mhz RAM and most PC games are ported over to the PC, so 2400Mhz is the new 1600mhz in a sense

Actually, memory speeds above 1600 are beneficial for AMD pricessors only, which are those consoles you speak of.

It's been shown time and again that for gaming, there is nearly nonexistent benefit to go faster than 1600 with Intel processors.

Finally, as has been noted, SB IMC doesn't like to go that high.

@OP
did you set voltages accordingly for those sticks when trying over 2133(with out XMP) manually? +1 to any advantages of overclocking your memory, in game you wont notice one bit of it, that said hope you got the receipt most places will not take back memory for warranty(if its a store)

That is another good point. XMP Profiles will set the Voltages to 1.65V and QPI/VTT to 1.2. You will have to do that manually also.

Lowest settings possible.

 

[EarthDog]

Lowest settings possible.

Which exaggerates the difference quite a bit I would imagine....

Have you done this testing with the highest settings? If so, were the results similar as far as percent difference between the kits? I would be curious to see real world results.


Damnit... I went OT again...sorry OP.

Cheers for the responses lads

I got it working now after clearing the CMOS.. lovely.. RAM working now at 2133Mhz with 9 11 11 25.. not bad.. 25-29FPS increase in GTAV for starters so I am as you can imagine very happy xD

Take that EarthDog

Wut? How much did you got more?

 

[EarthDog]

Lol hahahaha "take that" ?!!! What are you, 10?

25-29 fps increase eh? Curious how you measured that...before and after. And what the before result was in the first place. Do tell...

Edit: though one thing I JUST noticed (though I mentioned it much earlier anyway) I see that you have multiple gpus. Faster memory helps more with multiple GPUs than with a single.

 

[Mussels]

Even i said i got decent gains from the higher speed ram... once OC'd, these CPU's love the faster ram

Glad you got it working, I was going to ask if the Ram was an older set designed for Sandy Bridge, or for Ivy Bridge and newer as that could affect performance.
When I bought Ram for my Z77 it stated it had to be designed for that chipset as older Ram may not function correctly.

I actually hated XMP since it came. For example on X58 XMP shot the uncore voltage to 1.35V with corsair XMS set... I know... it works on auto then... but I didn't like the idea really...

Ahhh come on I was clearly taking the piss.. don't be so serious lad.

Anyway I measured it at a specific point in the game and I noted down my results before and after, I had my brother here beside me and his initial response was "WTF seriously?.. 30Frames!!" I also got an increase in Far Car Primal where I was getting on average 40FPS before the upgrade and now I am comfortably playing at 60fps, when I take the fps cap off it went up to 65fps.

I couldn't tell you to be honest, never thought to search for that information.

 

[EarthDog]

Perhaps try running the built in benchmarking utility instead.

EDIT: Another thing, what are the ACTUAL FPS you started with? Did you add 30 on top of 150 or add 30 from 50? Big difference there in % increase.

Sounds like you found the magic unicorn if those results hold true with empirical testing!

 

[lorraine walsh]

If a board gets overloaded with RAM, the board may have to down-clock the ram in order to maintain stability.

This is extremely prevalent in cases in which you have 4 DIMS populated by high speed sticks. The controller might not like it and down-clock itself if it can't support it.

 

[EarthDog]

It doesn't down clock itself. It just doesn't work without adding other voltage. YOU can down clock it...otherwise on first boot, it uses JEDEC specs lime every other stick does. Then you switch to xmp profile and it should work. If not, you need to add SA or IO voltage to help it reach those speeds.
