What RAM can I get for a Gigabyte GA-X58A-UD5

Alright guys this is my first post on any hardware forum ever, so bear with me if I make any mistakes or blunders!

So, I'll get right down to business: I need to upgrade two parts of my pc for some upcoming contracts. One is a 3d contract for which I need the maximum amount of GPU ram available, and the other is a video editing contract for which I need a lot more ram than I currently have. I've been advised by my colleague that the sweet-spot of RAM for me to aim for is 16GBs.

My current system is as follows:

Motherboard: Gigabyte GA-X58A-UD5 (rev. 1.0)
CPU: 1st Gen i7 920 "Bloomfield"
RAM: 6GB G.Skill 1600 mhz (which apparently I've been running at 1066 for two years and had no idea)
GPU: 2 x gtx470. MSI stock + Gigabyte factory OC
HDD: 2 x 1TB seagate x7200, 1 x 2TB seagate x7200

I'm going to be getting the eVGA gtx680 GB for a new video card, but for the ram I'm kind of stuck. My problem is that my motherboard only supports DDR3 2200/1333/1066/800 MHz memory modules and I can't find any specifically 2200 MHz modules right now. Everything is 2133 or 1866.

I'm trying to avoid buying faster ram that runs at a slow speed on my motherboard because it seems like a waste of money. But I do need to get 16GB and I may as well buy a full kit to do so because i'm not even getting the most out of my current ram due to it not being supported at it's intended speed.

So, basically I need advice on what modules would work with my current motherboard. I had been looking at come Corsair Dominator kits but I can't find any that I know will work at their intended speed. I would like to stick with Corsair if possible.

Obviously my easiest solution right now would be to buy a whole new pc, and it's something I have considered (have one tentatively specced out), but that's also by far the most expensive route. I would like to avoid that for now. My plan is to just upgrade my gpu and ram for this project - and worry about getting a whole new pc (ivy bridge, ssd, etc) later.

Additionally my friend might be willing to purchase one or both of my gtx470s, which would be great as it saves me some money. My main problem with that though is if I sell both, I have no video card to put back into this machine when I eventually build a new machine and move the gtx680 over. That's why I'm thinking of keeping at least 1 of them. I would love to hear any suggestions and/or advice anyone has for what to do with my spare pc parts if I do end up selling my 470s and build a new machine (for the 680) in the coming year. Should I keep both and put one back in this machine, and use the other as a physX card alongside the 680, or is that just wasted power/extra heat generated in the case?

Recap:

My main concern right now is what RAM I can get that would be 2200mhz or similar, and work at its intended speed in my current mobo.

I would also like and appreciate advice on what to do with my current machine/parts in the event that I build a new one (for the gtx680 + new ram) in the coming year.

Corsair's own website doesn't list any 2200 ram with tripple channel support, and even if you found it, it would be too expensive. I would wait for your next board/cpu/ram upgrade. I'm not a fan of paying extreme prices for small performance gains.

Welcome to Tom's Forum! :) 

You're not stuck with the listed Frequencies, and anything >DDR3-1866 is going to require a BCLK OC to remain stable.

Q - What are the values listed under MIT and in the 'System Memory Multiplier' menu options?

I looked in the manual and it listed no information. From the specs I know (16.5, 10, 8, 6), but I would assume at least (12 & 14) are also available and 16.5 is really odd (2200/133.33=16.5) -- Support for DDR3 2200/1333/1066/800 MHz

OC Example: BCLK -> 167MHz * 12 = ~DDR3-2000.

Hey thanks for the welcome, and the reply!

Okay so if I go for 2200 I would need to OC my block (for cpu?). What if I specifically bought 1866? It would run at 1333 or 1066 because it's not supported, correct?

I'd be willing to pay more for larger modules and get 18GBs, but I'm trying to get 16GB or higher. If I could get 18GB that runs at 2200 mhz that would be ideal, I just haven't seen any kits like that in my searches. What if I bought two kits (of the same) or 8GBs for 16? There would be no issues, correct?

Before I can give you advice, boot into your BIOS and answer this question:

"Q - What are the values listed under MIT and in the 'System Memory Multiplier' menu options?"

Alright so I just fiddled around a bit with my MIT settings - I've been meaning to clock up my cpu for a little while now.

Here are my current settings (I'm not sure if I have all the ones you requested, but I hope so):

CPU Clock Ratio = x21 (3.36 GHz)
QPI Link Speed = x36 (5.72MHz)
Uncore = Auto
BCLK Frequency = x 160
System Memory Multiplier = x10

Originally the CPU Clock ratio was x20, and the BLCK Frequency was x133. Everything else was auto (which meant the system mem multipler was x8)

So my RAM, according to my BIOs, should now be running at 1600 and CPU-Z records my DRAM Frequency at 800MHz (though it is triple channel...not sure if that's correct or not).

I do need to increase the amount of RAM I have. Would I be better off getting 16 (or more) GBs of RAM running at 1333 MHZ, or should I get the amount of RAM I want of any speed and let it run slower on my mobo?

The problem is I need more RAM for this project - but I'm not ready to upgrade my whole system yet.

There is this kit I found on Newegg: http://www.newegg.com/Product/Product.aspx?Item=N82E168...

It's only 1333, but fairly cheap and two sticks of 16 GBs.

That means I'd be running the RAM in dual channel mode, correct? Or are the channels not the same as the physical modules and the slots they occupy?

Duh, what values are part of the --- 'System Memory Multiplier'???!!!!

From the specs I know (16.5, 10, 8, 6), but I would assume at least (12 & 14)...

As a preference, System Memory Multiplier -> 12 (if an option) than 10 and BCLK of 160MHz ... and yes you're running DDR3-1600 to spec ; DDR3 = Double Data Rate revision 3 ... so DRAM Frequency in CPU-z is 800MHz * 2 = DDR3-1600.

Add this to your existing ram and you'll have 12 gb (which is plenty) http://www.amazon.com/Corsair-TR3X6G1600C9-PC3-12800-16...; Check your ram label and google it. See what voltage it's supposed to run at. No point in wasting your old ram. You have lots of options for speeds less than 2200.

The values mine offers are: 6, 8, 10, 12, 14, 16, 18.

I could do 12 but at 160 BLCK it would put my RAM above 1600 so wouldn't that be dangerous territory for it?

Yeah I'm not too thrilled on my old RAM going to waste - but I can always put it in another pc of mine which has a dual core cpu.

I've heard from a lot of places that mixing different kits is not a good idea, certainly not different brands. Though obviously you did pick the same speed which is good.

If I wanted to go for 16GB though what options do I have in terms of speeds to choose from?

Here's an example from newegg http://www.newegg.com/Product/Product.aspx?Item=N82E168...

Why would Gigabyte not support 1600 inherently on this mobo when there are so many kits at 1600 and almost none at 2200 that I've seen?

An i7-920 can run DDR3-1600 EASY with a (BCLK -> 133.33MHz * System Memory Multiplier -> 12) = DDR3-1600 and it's a heck of a lot easier on the CPU and temps than a BCLK of 160MHz * 10. I have a dozen i7-930's doing it for the as 2+ years.

Don't forget to set the DRAM Voltage to rated (typically 1.64v is fine for 1.65v kits) nor DRAM Timing Selectable -> Quick and set the (CAS-TRCD-TRP-TRAS-CR) e.g. 9-9-9-27-2T, etc.

Real supported Memory with 6, 8, 10, 12, 14, 16, 18
6 * 133.33MHz = 800MHz
8 * 133.33MHz = 1066MHz ; Default
10 * 133.33MHz = 1333MHz
12 * 133.33MHz = 1600MHz
14 * 133.33MHz = 1866MHz
/anything faster would require a BCLK of 160MHz~167MHz to remain stable:
16 * 133.33MHz = 2133MHz
18 * 133.33MHz = 2400MHz

Oh okay that makes a lot more sense now. I'll definitely crank that back down in a bit and set it to 12.

In terms of new RAM should I ignore the "supported" speeds by my mobo and just get whatever (i.e. 1600, 1866, 2133) despite them not being listed as supported ?

What about this 1866 kit? http://www.newegg.com/Product/Product.aspx?Item=N82E168...

Or even this 2133 one? http://www.newegg.com/Product/Product.aspx?Item=N82E168...

Frankly, unless you're going to OC the CPU there's no point in getting anything faster than DDR3-1600 3x4GB. Gigabyte clearly isn't posting the correct specs for RAM. Further, your MOBO & CPU 9.9/10 can support 6x8GB (48GB) if needed.

It's best to purchase Tri Channel kits for the X58; 3x_GB or 6x_GB.

For the X58 my preference is Mushkin, Corsair or Kingston HyperX:
I would choose one of these kits 3x4GB (12GB) - http://www.newegg.com/Product/ProductList.aspx?Submit=E...

or 6x4GB (24GB) - http://www.newegg.com/Product/ProductList.aspx?Submit=E...

Yeah I'm not sure what is going on with the specs they listed.

I actually do have the cpu slightly Overclocked right now, though with the BLCK at 133 as you suggested I can only get it to 2.8 (from 2.67). If I move the BLCK back up to 160 I can get it to 3.37.

Frankly I'd like to overclock the cpu as much as I can while keeping the QPI link speed at 6.4.

The reason for that limitation is that the board only supports QPI up to 6.4 and I'd tried to overclock it two years back with some stability issues. It was fairly stable, but it would always run into some problems - which I realized after a while were because the QPI had been at 7.2 at the time. Too much for the board to handle.

Am I correct in thinking I can't clock my cpu passed 2.8 while leaving the BLCK at 133? (My multiplier is already at x21 - the cpu limit)

The i7-920 runs 2.66GHz to 2.93GHz (stock) and since the CPU multiplier (22 max) is fixed then only way to OC is to raise the BCLK and adjust the voltages (e.g. vCore/LLC/Phases); info - http://ark.intel.com/products/37147/Intel-Core-i7-920-P...(8M-Cache-2_66-GHz-4_80-GTs-Intel-QPI)

Also DDR3-1600 will carry you to whatever OC you can get the CPU stable. My gaming rig has an i7-980X and regular PC an i7-3930K, the X79 uses DDR3-1600. BCLK 160MHz * 10 (RAM DDR3-1600) and 160MHz * 22 (OC CPU 3.52GHz).

Okay perfect. So 1600 would be adequate even if I overclock the cpu as much as I can? (likely 3.5/3.8 IF I can get it that high and stable).

I ended up going with the G-Skill 24 GB kit. Thanks again for all your help Jaquith! I really appreciate it!

One last question for you.

So I am going to try to overclock my cpu some more to alleviate any bottlenecks with the ram and video card. Right now it's at 133 as I mentioned. If I want to keep the ram at 1600 I need to use a BLCK of 133, 160, or 200 - correct ? Those are my only options based on the memory speed multipliers I have to choose from?

If so 200 isn't even an option since it would put my QPI speed well above 6.4 which the board cannot handle. So my only options are 133 (which is a very slight overclock at x21) and 160 which is about 3.36 GHz.

Am I correct in my calculations/reasoning?

If so, are there any other methods I can use to get my CPU up or are these pretty much the limits I have to live with?

You're not locked in to a handful of BCLK, you can use any numbers that provide the best stability. I have no idea what your MOBO + CPU + RAM can handle, but I have ballpark ideas I generally steer clear of CPU OC section because to do it correctly take a lot of time and playing with all sorts of BIOS tweaks.

RAM and BCLK:
1600 / 133.33 = 12
1600 / 160.00 = 10
1600 / 200.00 = 8

1600 / 180.00 = 8.8 ; choices under or over clock the RAM ; 8 * 180 = 1440 or 10 * 180 = 1800 (play with the CAS (lower) and DRAM Voltage (+0.05~+0.10v) but you'll probably need to also raise the QPI/DRAM Voltage (1.20v~1.30v)

Here's some numbers and good info (calculations) - http://vip.asus.com/forum/view.aspx?id=2008122019104023...
