These are all the links that come to mind when sandybridge users think about overclocking or choosing RAM:
Quote:
These articles not only help 1155 users choose RAM but also show what overclocking them really does in terms of benchmarking and everday usage. I recommend reading those before overclocking RAM or choosing it for Sandy!!

This is my take on the whole sandybridge RAM:

After reading those articles I have some what come to my own conclusion about choosing and overclocking RAM. If you've read the articles you would have seen how the high speeds and low latency affect performance and general usage. With that said, I believe that a standard kit of 1.5v is good enough for general everyday usage, the difference is VERY minimal. Choosing RAM depends on how much you want to spend, how much capacity you need and whether or not you're going to be benching more or less frequently. On that note if your looking for a moderate overclock without sacrificing the amount of RAM then choose any of the ones under the 'bit of overclocking headroom', however with those, there are some with the low voltages.

You might say "what is the point of overclocking them then if the difference is minimal?" well that is because of benching ie. super pi etc. I have found that high speeds and low latency impacts benching more than anything else. Now we have found two types of 'conditions', benching and everday usage.

THIS kit is pretty decent for benching, 4GB much easier to overclock and maintain low latency, it comes at 1600mhz with 6-8-6-24 with 1.5v and costs $60.

Now pretty much the same kit but pre-overclocked to 2200mhz, THIS kit costs $150, same 4GB, 7-10-10-27 with 1.65v.

I'm quite certain that $60 one could reach 2133mhz with 1.65v with ether 7-8-7-27 or 8-8-8-27. That said don't jump straight into pre overclocked kits, some cheaper ones can probably do the same or even better. With that said, if your not looking for RAM for benhcing then the ones I mentioned aren't for you instead look for some decent 1.5v rams.

The CL9 1.5v seem to be the most popular ones amongst those that are not really interested in benching and because they have found that it doesn't make much difference in everday usage. If you want the capability of maybe benching now and again but don't want to fork out that much then I would advise you to get a 4GB and either a CL7 or CL8 kit. Not interested in benching and believe that your good enough for general everday usage then get the CL9 1.5v kits. End of the day DDR3 is DDR3, it should work across the board, the only thing to consider is voltage. Made for a particular chipset is BS, it'll more than likely work, I mean there ain't no reason not to. The G Skill, Corsair kits etc are pretty good and im sure you won't have any problems with them, unless the RAMs are rated 1.8v+ or something you should be fine.

Due to recent developements in my brain lol It has come to my attention through reading various articles, threads and receiving help for some of the member's here (badatgames, FTW 420, Bassplayer, Noguru) that overclocking capabilities lies truly with the Integrated Circuit (IC) of the RAM. There are various type of IC, HERE is a good list of them. I will try my best to explain some of the more popular ones in the benching section below for those that are not familiar.

Some examples:

For general everday usage (1.5v):

G.SKILL Ripjaws X Series 8GB (2 x 4GB) 1600mhz CL9 1.5v

G.SKILL Sniper 8GB (2 x 4GB) 1600mhz CL9 1.5

CORSAIR Vengeance 8GB (2 x 4GB) 1600mhz LOW Profile CL9 1.5v

CORSAIR Vengeance 8GB (2 x 4GB) 1600mhz CL9 1.5v ----** REVIEW & OVERCLOCKING **----

Mushkin Enhanced Blackline 8GB (2 x 4GB) 1600mhz CL9 1.5v

Mushkin Enhanced Silverline 8GB (2 x 4GB) 1600mhz CL9 1.5v

Mushkin Enhanced Radioactive 8GB (2 x 4GB) 1600mhz CL9 1.5v

Pick the cheapest from the above if you ain't fussy over the colour or whatever, there all pretty much the same spec and price. The review and overclocking for the Vengeance kit could be used for the other kits aswell, however these kit's vary so does their potential so one could do better than the other but I really don't see it going higher than 1866 with decent timings, with these kits, you could probably get away with 1.65v and those timings at 1866 but I don't think you can go higher than that without crazy votlage and loose timings. Below are ones that are a little better:

Maybe a bit of overclocking headroom these 8GB kits, little more expensive than the ones above:

G.SKILL Ripjaws X Series 8GB (2 x 4GB) 1600mhz CL8 1.5v

CORSAIR Vengeance 8GB (2 x 4GB) 1600mhz CL8 1.5v

(Below 1.5v)

Mushkin Enhanced Blackline 8GB (2 x 4GB) 1600mhz CL9 1.35v

G.SKILL Sniper Low Voltage Series 8GB (2 x 4GB) 1600mhz CL9 1.25v ----** REVIEW & OVERCLOCKING **----

These kits are could actually be pretty good for a little benching aswell, that's only if you can overclock them. Some have shown really bad overclocking capabilities, such as the CORSAIR Vengeance LP 8GB (2 x 4GB) 1600mhz CL9 1.35v. Yes the voltage is low and you would tihnk that it would overclock, but unfortunatly it wouldn't budge, Check the REVIEW of the corsair kit HERE.

That's not to say that the other lower voltage ones like the sniper 1.25v and the mushkin 1.35v would be the same, if you hit the review button on the snipers, you'll be able to see what it's capable of, not sure about the mushkin's though, but I would like to think that it does have some overclocking potential, hopefully not the same as the Corsair LP.

The RipjawX are quite appealing with the latency at CL8 and the voltage at 1.5v. The Blackline CL9 and Sniper CL9 are in that list of 'bit of overclocking headroom' because of the low voltages compared to the other's, so they definitely have potential. Going by price and potential, picking one of these may be tough so ask away....

The 1.35v Mushkins and 1.25v Sniper's are pretty decent, low voltage = win, for some it may be worth it and I certainly recommend it as you can more than likely tighten the timings with a little votlage bump. So the 1.35v mushkink's and the 1.25v Gskill Sniper's are really the ones to go for if you want just a little bit better and the capability of overclocking and tightening them. Those are great for everday usage and a little light benching now and again. Ultimatly the key aspect is the low voltage.

I would always recommend getting the low voltage ones, whether it be 1.5v, 1.35v or 1.25v, however, both the mushkins and snipers that are below 1.5v have a latency of 9 as opposed to the others that have latency 8 with 1.5v, so it's not that simple. That's a tough one to choose, do you go for the ones that are below 1.5v, say the 1.25v ones and would it do better than the cl8 1.5? Not sure but I would hope so. Price is also a factor here. But like I said, problems deciding??? ask away here.......

For general everday usage (1.5v):

CORSAIR Vengeance 8GB (2 x 4GB) 1866mhz CL9 1.5v ----** REVIEW & OVERCLOCKING **----

Apparently the Corsair's above are truly terrible for overclocking, however, it works just fine under XMP which it's suppose to.

G.SKILL Sniper Series 8GB (2 x 4GB) 1866mhz CL9 1.5v ----** REVIEW & OVERCLOCKING **----

According to the review above, again the overclocking capability was lacking, however they did mange to run it at 2133 even though the timings were 11-15-15-38, which to be honest is just crap lol.

G.SKILL Ripjaws X Series 8GB (2 x 4GB) 1866mhz CL9 1.5v ----** REVIEW & OVERCLOCKING **----

Now these are a little surprising, reviewer's above were able to overclock these to 2133mhz with 9-11-10-28, T2, at 1.56v (Stable after hours of prime blend). Max overclock of 2155Mhz, with timings at 10-12-10-28 with a command rate of 1T at 1.6v DRAM, and 1.2v QPI (VCCIO). Pretty impressive if I say so myself. Please read the review for more details.

Kingston HyperX 8GB (2 x 4GB) 1866mhz CL11 1.5v

Not so sure about those. C11 doesn't sound all that good.

GeIL Evo Two 8GB (2 x 4GB) 1866mhz CL9 1.5v

Similar timings as the Ripjaw X, however can't find any reviews on them, I'll update once I find anything.

GeIL EVO CORSA Series 8GB (2 x 4GB) 1866mhz CL9 1.5v ----** REVIEW & OVERCLOCKING **----

Same timings as the Evo Two, however the review stated atleast a 5% overclock. Read review for more info.

Crucial Ballistix 8GB (2 x 4GB) 1866mhz CL9 1.5v ----** REVIEW & OVERCLOCKING **----

Unfortunately I couldn't find any other reviews on these Ballistix RAM's, however a quick glance says that they are pretty decent and can clock to 2133mhz without any issues, not bad for a yellow kit

Mushkin Enhanced Redline 8GB (2 x 4GB) 1866mhz CL9 1.5v

CORSAIR Vengeance LP 8GB (2 x 4GB) 1866mhz CL9 1.5v

CORSAIR DOMINATOR GT 8GB (2 x 4GB) 1866mhz CL9 1.5v


For ALL benching purposes:

G.SKILL Ripjaws X Series 4GB (2 x 2GB) 1600mhz CL7 1.5v ----** REVIEW & OVERCLOCKING **----

These are the ones I got and I managed to overclock them to 2133mhz with 9-10-9-27 1T @ 1.65v. Here's my little review.

G.SKILL Ripjaws X Series 4GB (2 x 2GB) 1600mhz CL6 1.5v ----** REVIEW & OVERCLOCKING **----

As we know by now that Sandybridge has a lack of BCLK tweaking, making overclocking RAM on SB quite difficult, that and the fact that the 2400 strap doesn't seem to work on the Asus mobo's. Anyway as mentioned before the overclocking capabilites lies with the Intergrated Circuit of the RAM. The various types of IC will be talked about in the thread and the best ones will become apparent as we discover their potential with Sandy. The way you can tell what IC you have is by the timings, (courtesy of Bassplayer for helping me out here)
Quote:
The stuff you find most often in enthusiast chips are Elpida Hypers, MNH-E (the earlier revision that was prone to die) and MGH-E, as well as Elpida BBSE, PSC (Powerchip), and apparently Hynix has some performance modules.

For example, the following are Hypers:

1600 6-6-6, 1600 6-6-5
1866 7-8-7, 1866 7-7-7, 1866 7-7-6
2000 8-8-8, 2000 8-8-7, 2000 7-8-7, 2000 7-7-7, 2000 7-7-6
2133 8-8-8
2200 8-8-8
2250 8-8-8, 2250 9-9-9 (some)
2300 9-9-9 (some)
Misc reviews, 16GB included:

16GB (4x4GB) G.Skill RipjawsX (2133mhz) F3-17000CL9Q-16GBXLD 9-11-9-28-2T

8GB (2 x 4GB) Mushkin Enhanced Blackline (2133mhz) PC3 17000 Model 997015 10-11-10-28

1.65v RAM on Sandbridge
As you can see majority of the kits I have mentioned are either 1.5v or below, that's not to say that a 1.65v kits won't work, but that is the highest you should really be running these RAMS for 24/7 anyway. General consensus is lower voltage is always better, however, 1.65v WILL work if you ALREADY have it. Dopamin3 recently, bought this next bit of info to my attention (big thanks):

Just to correct the original post in this thread, the VCCIO voltage does not have to be within .05v of the DRAM voltage as TwoCables pointed out. This was only a limitation for the X58 platform (well 1366 CPUs really) and not present in Sandy Bridge.

Sandy Bridge does not require there to be a maximum of 0.5v between the VDIMM value and the VCCIO and VCCSA values when 1.65v voltage modules are used.
If you have a 1.65v keep it and use it with sandy, if you want to buy a new kit, any of the ones mentioned above for your particular usage will suffice.

Mixing RAM
One other thing, mixing RAM isn't as straight forward as you think, most RAMs are advertised by showing only the first 5 timings, command rate 1T and 2T, however there are other's to consider. That's why it's best to stick to one 'kind'.

So then they would take that into consideration when asking the question, can I add this set of Mushkin Redline, to this set of G.Skill.

Dram Timing Control
DRAM CAS# Latency: 7
DRAM RAS# to CAS# Delay: 8
DRAM RAS# PRE Time: 7
DRAM RAS# ACT Time: 20
DRAM RAS# to RAS# Delay: 5
DRAM REF Cycle Time: 90
DRAM Write Recovery Time: 13
DRAM Read to Pre Time: 8
DRAM Four ACT Win Time: 24
Back to Back CAS# Delay: Auto
DRAM Timing Mode - 2N
There are also more, but you get the picture!

I'm getting a 2500K and MSI P67 board tomorrow. A bit ashamed to admit it's only an MSI P67A-G43, but I wanted to try a budget board for a change, I've spent enough on higher-end boards for a while.
If it doesn't work out to be a good enough board, I'll give it to the neighbor's dog to chew on:p
My first crack at SB, I've been reading up on it for quite a while, and decided to go for it.
Your Sandy Stable Club has been an excellent source of information, this thread and links should also be very beneficial.

Enough praise for now:p I'm planning on using the set of GSkill ram in my sig, I know that it's a bit dated, being from a P55 build, but thought I may as well try it out. Of course I will find out soon enough if it works ok with my board and cpu, but are there any issues anticipated with using this kit?
I'll flash the board with the latest bios, as soon as I set it up.

I agree about the chipset specific hype as well. If that were the case, then those using an AMD setup would be having to find their own compatible ram.
This GSkill isn't an oddball high-voltage kit, just rated at 1.65v. like most of the earlier DDR3 was. I guess the 1.65v. vs 1.5v. difference with the newer kits isn't a problem with a P67 chipset.
Only reason I may buy a new kit is because of the low prices for ram now, an 8GB kit is cheaper than the 4GB kit was a year ago:p

Munaim, I was just thinking about which ram to get, and im stuck between a 8Gb g.skill CL8 kit at £71 and a 8gb CL9 kit at £44, the only difference is literally the 1 timing.

Would that be worth spending extra £30? I would spend it, if i knew it meant I could take an overclock higher..I dont wanna go cheap and find out that is limiting my overclock.

I personally would go for a 4gb kit that I can overclock, something like low latency and high speeds would do great in benching, super pi etc. 4GB kits are easier to overclock than 8GB kits.

As explained overclocking the RAM yields very little performance increase in everyday usage, that said get the £44, however you want to do benching now and again then go for the £71 one, but as I explained before, 4GB kits are the way forward for benching.

If you do light benching then go for these: http://www.overclockers.co.uk/showproduct.php?prodid=MY-056-GS

For gaming 4GB is more than enough these days, but if your content with 8GB then get the CL9 1.5v £44, the extra £30 would have been worth it for the other one if it was CL7, but then again it is better than the £44 one, so you need to make a decision.

Read the article above and it'll help you decide what you want.

Hope that helps.

My main concern was that if i bought a cheap ram kit, when I go to overclock the CPU, I dont want the ram to be unstable and hold it back...would that cheaper 8GB CL9 g.skill kit hold me back?

not the case, RAM is not linked to the CPU, as overclocking is done through the multi rather than the BCLK.

You should be fine bro. trust me, any CL9 1.5v kit would do just fine.

People who are very into benching, but at the same time want more RAM for regular use - Why not have one 2x4GB kit for 24/7 general use, and one 2x2GB kit for benching
wink.gif


When done benching, either use that 2x4GB kit until the next benching session, or just mix 2x4GB + 2x2GB kit for a total of 12GB and set timings manually

thanks bro
biggrin.gif


getting two kits could equal to more costs, a mediocre kit with CL7/CL8 can be had for a good price without going overboard (that's the 4gb kits), that allows the everday users to maybe hit some nice bench's once in a while. With that said, I would say there are three types, bencher's, part-time bencher's and everyday usage guys/gals.

Some people aint into the whole benching thing while some are, those that aint could just go for a regular CL9 kit with 1.5v which is not costly at all.

It's difficult to get 8GB+ and high speeds and low latency without spending a fortune so in that case two kits could essentially work out better.
