Ripjaws X compatibility

[dirtywhitellama]

Wondering if anyone could tell me for sure (not just speculating ) if this memory,
http://www.newegg.com/Product/Product.aspx?Item=N82E16820231428&nm_mc=EMC-IGNEFL020111&cm_mmc=EMC-IGNEFL020111-_-EMC-020111-Index-_-DesktopMemory-_-20231428-L0B

which says it is for P67 and H67, will work on a P55 board with an i5 760? Specifically probably either
ASUS p7P55D-E PRO
http://www.newegg.com/Product/Product.aspx?Item=N82E16813131621
or ASUS p7p55d-e LX
http://www.newegg.com/Product/Product.aspx?Item=N82E16813131620


Personal experience would be especially appreciated!

Thanks

I have no personal experience but can honestly tell you there is absolutely no difference between regular Ripjaws and the new X series working on an 1156 or 1155 platform.
There are still both DDR3 dual channel ram kits.
The new X series is 4gb modules and 1.5v which is kinda nice actually because that's an 1156 mobo's default ram voltage.
You won't have to change the dram voltage in the bios for it to operate at it's speed.
The main reason the new kits are being touted as p67 SB optimized is because the 1155 boards accept 32gb of ram as opposed to 1156 capacity of 16gb.
I smell 8gb ram modules.

thanks, thats generally the impression I've got but it seems nobody is really trying it (I guess nobody wants 1156 anymore, heh) I probably will end up getting them if I can, seems all the motherboards I want are out of stock now though

I would recommend the following Kits, 4GB in particular are BIOS/Chipset picky and the IC's are different in the 'vanilla' Ripjaws. You'll notice the chipset support is different; there have been other simular posts and G.SKILL themselves confirms there are IC differences and inherent compatibility issues. The cost is the same.

At SPD either 'kit' should work.

G.SKILL Ripjaws Series 8GB (2 x 4GB) 240-Pin DDR3 SDRAM DDR3 1600 (PC3 12800) Desktop Memory Model F3-12800CL9D-8GBRL http://www.newegg.com/Product/Product.aspx?Item=N82E16820231314&Tpk=F3-12800CL9D-8GBRL

G.SKILL Ripjaws Series 8GB (2 x 4GB) 240-Pin DDR3 SDRAM DDR3 1333 (PC3 10666) Desktop Memory Model F3-10666CL9D-8GBRL http://www.newegg.com/Product/Product.aspx?Item=N82E16820231311&Tpk=F3-10666CL9D-8GBRL

 

[dirtywhitellama]

The cost is not the same (for the 1600), I can get the ones in the original post for $90 right now.

I just noticed the promo code. If I was ignorant to the fact of: 1. ICs are different, 2. 4GB sticks are very picky then I was say no problem. I have personally had BIOS that required updating and 4GB sticks that simply failed, and seen way too many 4GB compatibility issues in this forum. I care about my quality of advice. At SPD I'm pretty certain they'll work, at rated I'm not certain.

If it were 'me' I would contact G.SKILL to verify 100% compatibility -> http://www.gskill.com/contactus.php

edit: BTW be leery of 'they should work' from G.SKILL; you want 'Guaranteed' to work.

 

[dirtywhitellama]

Sorry, what's SPD?

I did email GSkill already, haven't heard from them yet.

Afraid the only way I am gonna end up with 2x4gb is if they are on sale, otherwise going to get 2x2gb ECO's for about $75...
so Im just hoping

If you don't get a satisfactory reply from GSkill regarding the kit you're interested in may i suggest one?

I personally have this kit on an P55 1156 i5 760 platform and i'm very impressed.
It's also about half the price that i paid 1yr ago $120.
Worth buying two kits imo.
4GB is enough though.
Also will not cause problems with most aftermarket cpu coolers.(using with 212+)

SPD refers to the JEDEC standardized speeds, and not the Rated 1600 MHz speed. Example note the JEDEC vs RAM's speed of 1600 MHz - you need to multiply frequency X 2.

Hearing from G.SKILL is a lot better than the possibility of exchanging later, I would assume a lot of people are returning P67/H67 components so it might take G.SKILL a while to reply - you might want to call them...they're a good company.

Mushkin silverline is doing great in asrock p67 extreme4. Their heatsinks are shorter too in case you have a crazy cooler. Also, IMO no need to get ddr3 1600, 1333 wouldn't be noticeably different, promise 😉 They just add epenis tax to the RAM.

[excelerater]

I have a PC running ripjawsX on an AMD system.....bought by mistake,designed for SB LOL

Yea OK

 

[jaquith]

If you have 2GB sticks then none of this applies, and chances are the 4GB will run problem free even at rated speeds. However, 4GB sticks are a lot more - for lack of a long explanation - touchy. So the rated speed might not be obtainable.

The (2) Kits I posted above are Tested to run at rated speed.

I have seen too many times compatibility issues, so a simple check is the best advice possible. @excelerater I would recommend that even in your situation to Memtest 4 passes.

 

[dirtywhitellama]

festerovic, I'm looking for something that will work in p55, but thanks

If I cant find a suitable 2x4gb kit on sale by the time I buy I am just going to get these.
http://www.newegg.com/Product/Product.aspx?Item=N82E16820231321
The price on the higher speed and tighter timings on that 2x2GB kit is not so much that I mind (I probably wouldn't notice any difference but maybe someday I would like to overclock and figured it would be best to start with as good as I can) plus the ECO runs at 1.35V - maybe means nothing but I like that.

Don't know anything about mushkin. are they a decent company? just seemed to me that everywhere I look people recommend GSkill.

 

[jaquith]

What did G.SKILL say about the Ripjaws X?

If the $15 is too much then I would look at the F3-10666CL9D-8GBRL 1333 MHz. The sticks you linked above are okay, but the CAS disparity suggests a cheaper IC.

7-8-7-24-2N vs 9-9-9-24-2N - a tight CAS will almost always outperform a 'looser' CAS. Also, the difference between 1600 MHz vs 1333 MHz with the same IC might be 1~3 faster; whereas the with loose CAS + higher frequency can be slower than RAM with tight CAS + lower frequency.

 

[dirtywhitellama]

The sticks you linked above are okay, but the CAS disparity suggests a cheaper IC.

Not sure what you mean by this. they are 1600mhz at cas 7 , but only 4gb total instead of 8. (plus they run at 1.35v instead of 1.5v or 1.65v like most of the rest )

Still haven't heard from GSkill about it.


The item you suggest is 1333mhz, but also only cas 9. yes its cheaper, but for a good reason If I was really determined to start with 8gb I would get something like that, but I'm sure I could get by on 4gb until I get around to purchasing a 2nd 4gb set if I cant get a good set of 8gb on sale- in which case I will get something as fast and as low cas as I can.

 

[jaquith]

No, what you have is a manipulation to obtain a technical CAS 7 rating.

CAS disparity -> 7-8-7-24-2N
CAS tightness -> 9-9-9-24-2N

Example, look at the CAS + Frequency very carefully -- then look at the results {the quality of the IC is where it's at}:
Comparison Module #1: Mushkin Redline 996805 6-8-6-24 1600MHz
Comparison Module #2: G.Skill Pi Series 7-8-7-24 1600MHz
Comparison Module #3: Mushkin 998687 8-9-8-24 1866MHz
Comparison Module #4: Corsair Dominator TR3X6G1600C8D 8-8-8-24 1600MHz
Comparison Module #5: Kingston HyperX T1 9-9-9-27 1600MHz
Comparison Module #6: Mushkin Blackline 998677B 7-7-7-20 1333MHz
Comparison Module #7: Patriot Viper II Sector 7 9-9-9-27 1800MHz

My exact reply from GSkill:

Dear Customer

Should be no problem.

Thank you
GSKILL SUPPORT

now honestly on those results you posted (I'm assuming, since it doesn't say, that the first one is an fps?) I dont think any of that makes enough difference that I would even notice. I might overclock a little sometime but I am not out to get the best ever benchmarks or anything, I just want a computer that awesomely does everything I want 😉

But does that mean that
http://www.newegg.com/Product/Product.aspx?Item=N82E16820231321
and
http://www.newegg.com/Product/Product.aspx?Item=N82E16820231320
are probably basically exactly the same chip and I might as well save $5?

 

[jaquith]

LOL -> "edit: BTW be leery of 'they should work' from G.SKILL; you want 'Guaranteed' to work."

Those two G.SKILL's have different IC's, and I would rather have the 8-8-8-24-2N. People get suckered in on CAS rating, I get suckered in based upon proven performance {bench} & OC and I pay through the nose for 5~10 FPS improvements. In RAM you're lucky to see 2~8FPS from crap to big $.

You've got a 'greenish' light for the Ripjaws X from G.SKILL.

If I had your MOBO then 'I' would get 8GB Kits: Corsair Dominator CMP8GX3M2A1600C9, or G.SKILL F3-12800CL9D-8GBRL, or 4GB Kit: Dominator CMP4GX3M2A1600C8.

 

[dirtywhitellama]

Hey,
wanted to thank you a lot for your advice (even though I didn't take half of it 😉 ) Placed my order today and ended up getting the GSKill ECO at CAS8 that I linked a few posts up.
I'm not going for a benchmarking computer and don't have spare cash to pay through the nose for anything (if $105 is pricey for me, $150 is definitely pricey!) I don't think 5-10 fps out of ~200+ is enough of a percentage that I will really notice (as a user) at anything that doesn't run faster than my screen anyway.
anyhow thanks again!

Actually, there is. From what I have read, the XMP file is difference on the X model for better compatibility with the 1155 socket CPU's. One also has to watch the voltage required for SB ram. It prefers 1.5v and is in fact designed by Intel to use that voltage. Unless a person wants a lot of headaches, I suggest they: a) ensure the RAM is on the QVL for the respective mobo; b) the voltage is rated at 1.5v and c) use RAM with "Sandy Bridge" XMP code embedded or RAM without any XMP code. One should remember that RAM has been the single most common problem with new SB builds.

As for how much ram....the common recommendation these days is for 8Gb in 2x4GB DIMM's. Care has to be used as to which DIMM slots the RAM sticks are put into. ASUS usually recommends slots a2 & b2.

Hope this helps you.
