Question on mixing Rams

Im having trouble on my brothers rig where i tried to add more ram stick and his comp just wont boot at all

His specs are:

i5-2500k
Asus P8Z68 V pro.
G.SKILL 8GB (2 x 4GB) Ripjaws X Series DDR3 1600MHz 240-Pin PC3-12800

What i tried to do today was install an extra 8Gb so he can have a total of 16Gb of ram.

I tried to install the following:

MUSHKIN BLACKLINE FROSTBYTE 8GB (2X4GB) DDR3-1600

the comp wouldnt even post with the muskin sticks in... all i get is a red led above the ram slots. As soon as i took the muskins off the comp boots up.

Do I need to upgrade the bios on the mobo... if am i doing something that is wrong?


Secondary, I am in the process of getting parts for my rig as well. My specs are:

i5-2500k
Gigabyte UD3H
Corsair Dominator Platinum 8GB (2x4GB) DDR3 2133 MHz.

If i go out and buy another set of Corsair Dominator Platinum 8GB (2x4GB) DDR3 2133 MHz will I be having the same problem as my brother where the mobo will throw up a spasm?

You may have to manually set timings before you install the second set of memory. It's almost a sure thing that there are timings that will allow both kits to work together without issue, but if they have different SPD profiles, or aren't particularly friendly to high memory densities, the defaults may be unusable.

If you add another set of the same memory to your system, things should work automatically, but even this is not certain. Often you need slightly loser timings or more voltage for four DIMMs relative to two.

Don't get the platinum ram. They are good but overpriced so you really dont get what you pay for (you pay for the bling bling). Then better save some money to a better mobo and get a gigabyte UD5h and then get some cheaper ram that is just as good. G.ksill, Kinston or even samsung wonder ram (can OC better if you want to do that some day).

Well back to your brothers rig.
I think the problem is that the ram is not from the same manufacture. I think the rams need to be 100% identical before they work together

Corsair Dominator Platinum 8GB (2x4GB) DDR3 2133 MHz.

If i go out and buy another set of Corsair Dominator Platinum 8GB (2x4GB) DDR3 2133 MHz will I be having the same problem as my brother where the mobo will throw up a spasm?

Before I get started on the main question, let me say that in my opinion, while pricey, the high-end segment of the Corsair products, as a general rule, are very good.

Back to the issue at hand...

The problem with mixing ram is that unless you buy stuff without heat spreaders, you won't know what ICs are under the hood. It is mixing the ICs that causes the main problems, secondary issues arise if using different brands and the sub-timings are programmed differently. Again, let me be clear...timings and voltage info mean little when it comes to getting two different sets of ram to play well together. They are a starting point, but not much more.

Matching the memory ICs is key.

With GSkills, the 5th thru 8th digits of the Serial Number (not to be confused with model number) provide a clue as to the manufacturer of the ICs being used, but not the specific ones. The first 4 digits of that same S/N denotes the manufacturing year and week. If you match all 8 digits, or at least match the 5-8th and come close with the 1st four, then the odds are in your favor of having matching ICs even if you don't buy a quad kit.

Look here for more info on the GSkill numbering scheme:
http://www.xtremesystems.org/forums/showthread.php?283666-Figuring-out-G.Skill-s-SNs

Corsair uses a different approach. They use a version #, located just to the right of the timings and voltage info on the actual module label (not the box). The Corsair Dominator Platinum DDR3-2133 CL9 kit using Samsung HCH9 chips is marked as "ver4.13". If you were to later buy a second kit you would want to be sure that it matched up with the version number of the first kit that you buy. Of course, unless you buy it at a B & M store like a Micro Center, or Fry's, matching the version number with an online purchase is a bit of a gamble, except in those cases were only one version of the product was released.

Look here for the Corsair info:
http://forum.corsair.com/forums/showthread.php?t=68811

Kingston uses a different approach for identifying their modules' ICs...an IC code on the packaging's label, not on the module's label.

The following screenshot was posted elsewhere and I luckily I copied it before the site shut down



Mushkin, does not use a system, or at least one that has been identified to date. Most of the time they change the Model number, but they have on more than one occasion changed the ICs and kept the same model number.

Many of the others (Patriot, GEIL, Team, etc.) don't use any known system so you have to rely on reviewers and users that have removed the heat spreaders in order to know what is being used on a particular model.

Some of that info from reviewers and users has been compiled in the following two locations:

You're welcome and I'm glad that you consider it useful.

Much of what I've learned over the years has come from others sharing their knowledge and experiences and I try to pass it along when the opportunity arises. You don't have to look any further for an example than that last link that I provided. Many people have contributed to that knowledge base and we all benefit from it.

Edit:
Adding one more link which may be useful...and which is also a great example of someone sharing their knowledge. It is to a thread started over at XS by TaPaKaH (he is a member here that goes by Sam_OCX). In it he provides information / attributes on a variety of chips and is the best compilation that I know of. The original thread was previously hosted elsewhere and that was where the image that I posted about the Kingston IC codes originated.

lol God I love threads like that! Such threads remind me that I am not alone in my slavish devotion/obsession to, and about PC tech! I don't have to feel like I'm the only Geek around with a massive RAM collection. biggrin.gif Not to mention the information that gets shared. One simply cannot learn such things any other way. Again... much appreciated! thumb.gif

If you are into ram, and you haven't done so yet, perhaps you might want to check out this thread:

Good Lord, man! I shall be carefully checking your Posts from now on. You are a veritable font! lol seriously, I appreciate you taking the time to share this stuff. It is thanks to unnaturally generous guys like yourself that I went from a total tech illiterate, to an absolute nutcase who cuts traces, volt-mods, overclocks components almost as soon as they are out of the box, and who is currently fighting a losing battle to resist the urge to purchase a Hailea HC-500A 110V (1/2HP=790Watt cooling capacity) Waterchiller, (or something like it). So even though I now carry a terrible (and oh so costly) addiction to sweet, sweet tech... I consider myself to be the truly lucky recipient of a great store of knowledge. Knowledge which has been imparted to me in return for nothing more than my thanks and the obvious satisfaction that enlightened folks such as yourself gain from teaching. Sorry for the attempt at waxing profound... but I really think that folks like you do tremendous good for our community, and unfortunately you are often taken for granted. It is just human nature, I know. But I like to try to add a little bit of weight to the proper scale by showing some respect, and some gratitude. You certainly have both!

John
